Cells that are produced by germ cells through the process of meiosis are called ___.
-
Somatic cells
-
Gametes
-
Diploid cells
-
Binary cells
Correct Answer
A. GametesExplanation
Germ cells undergo meiosis to produce gametes. Meiosis is a specialized cell division process that results in the formation of cells with half the number of chromosomes as the parent cell. Gametes, such as sperm and eggs, are haploid cells that contain only one set of chromosomes. Somatic cells, on the other hand, are diploid cells that make up the majority of body tissues and organs. Diploid cells have two sets of chromosomes. Binary cells is not a scientifically recognized term.Rate this question:

Cells that have only one copy of an organisms chromosomes are said to be ___.
-
Somatic cells
-
Diploid cells
-
Haploid cells
-
Binary cells
Correct Answer
A. Haploid cellsExplanation
Haploid cells are cells that have only one copy of an organism's chromosomes. This means that they contain half the number of chromosomes compared to somatic cells or diploid cells. Haploid cells are typically found in reproductive organs and are involved in sexual reproduction. They combine with another haploid cell during fertilization to form a diploid zygote. Therefore, the correct answer is haploid cells.Rate this question:

A female gamete ___.
-
Is produced in the testes.
-
Is called an ovum or an egg cell.
-
Is called a spermatocyte.
-
Is called a polar body.
Correct Answer
A. Is called an ovum or an egg cell.Explanation
The female gamete is called an ovum or an egg cell. This is because in sexual reproduction, the ovum is the reproductive cell that is produced by the female reproductive system. It is the largest cell in the human body and is capable of being fertilized by a sperm cell to form a zygote, which eventually develops into an embryo. The term "egg cell" is also commonly used to refer to the female gamete, emphasizing its role in reproduction.Rate this question:

Which of the following is not true of sex chromosomes?
-
Sex chromosomes determine the gender of an individual.
-
Sex chromosomes contain information about all of your body tissues.
-
Sex chromosomes are labeled X and Y in humans.
-
Sperm cells have either an X chromosome or a Y chromosome.
Correct Answer
A. Sex chromosomes contain information about all of your body tissues.Explanation
Sex chromosomes contain information about the gender of an individual, not all of their body tissues. The sex chromosomes, specifically the X and Y chromosomes in humans, determine whether an individual is male or female. Other chromosomes, called autosomes, contain information about the body tissues. Sperm cells carry either an X chromosome or a Y chromosome, which determines the sex of the offspring during fertilization.Rate this question:

Chromosomes that have the same length, the same appearance, and the same gene loci are called ___.
-
Homologous chromosomes
-
Sex chromosomes
-
Autosomes
-
Chromosomal triploids
Correct Answer
A. Homologous chromosomesExplanation
Homologous chromosomes are pairs of chromosomes that have the same length, appearance, and gene loci. They carry the same genes, although they may have different versions of those genes (alleles). During meiosis, homologous chromosomes pair up and exchange genetic material through a process called crossing over, which contributes to genetic diversity. This exchange of genetic material ensures that offspring inherit a combination of genes from both parents. Sex chromosomes determine the sex of an individual, while autosomes are non-sex chromosomes. Chromosomal triploids refer to cells or organisms with three sets of chromosomes instead of the usual two sets.Rate this question:

- 7.
Chromosome that contain genes for non-sexual characteristics are called ___.
-
Homologous chromosomes
-
Sex chromosomes
-
Autosomes
-
Polar bodies
Correct Answer
A. AutosomesExplanation
Autosomes are chromosomes that contain genes for non-sexual characteristics. They are responsible for determining traits such as hair color, eye color, and height. Unlike sex chromosomes, which determine the individual's sex, autosomes are present in both males and females. Homologous chromosomes refer to pairs of chromosomes that carry the same genes, one from each parent, while polar bodies are small, non-functional cells produced during oogenesis. Therefore, the correct answer is autosomes.Rate this question:

The process by which two gametes fuse and offspring that are a genetic mixture of both parents are produced is called ___.
-
Sexual reproduction
-
Asexual reproduction
-
Binary fission
-
Sexual maturation
Correct Answer
A. Sexual reproductionExplanation
Sexual reproduction is the correct answer because it involves the fusion of two gametes, or reproductive cells, from two parents. This process results in offspring that inherit a genetic mixture from both parents, leading to genetic diversity. Asexual reproduction, on the other hand, involves the production of offspring without the involvement of gametes or the combination of genetic material from two parents. Binary fission is a form of asexual reproduction in which a single organism divides into two identical offspring. Sexual maturation refers to the development of reproductive maturity, but it is not the process of producing offspring through the fusion of gametes.Rate this question:

Which of the following is not true of fertilization?
-
Fertilization results in a diploid cell.
-
Fertilization results in a cell called a zygote.
-
Fertilization is the fusion of an ovum and a spermatozoa.
-
Fertilization occurs in all life forms.
Correct Answer
A. Fertilization occurs in all life forms.Explanation
Fertilization is the process of fusion between an ovum and a spermatozoa, resulting in the formation of a diploid cell called a zygote. However, it is not true that fertilization occurs in all life forms. Some organisms, such as bacteria and certain plants, reproduce asexually and do not require fertilization for reproduction. Therefore, the statement "Fertilization occurs in all life forms" is not true.Rate this question:

A cell that has two copies of each chromosome is said to be ___.
-
Diploid
-
Haploid
-
Triploid
-
A gamete
Correct Answer
A. DiploidExplanation
A cell that has two copies of each chromosome is said to be diploid. This means that the cell contains a complete set of chromosomes, with one copy inherited from each parent. Diploid cells are found in most organisms, including humans, and are responsible for the growth and development of the organism. In contrast, haploid cells have only one copy of each chromosome and are typically involved in sexual reproduction, while triploid cells have three copies of each chromosome and are often the result of genetic abnormalities. A gamete is a specialized haploid cell involved in sexual reproduction.Rate this question:

A form of nuclear division that divides a diploid cell into haploid cells and produces gametes is known as ___.
-
Mitosis
-
Meiosis
-
Cellular regeneration
-
Binary fission
Correct Answer
A. MeiosisExplanation
Meiosis is the correct answer because it is a form of nuclear division that specifically occurs in diploid cells and results in the formation of haploid cells, such as gametes. Unlike mitosis, which produces identical daughter cells, meiosis involves two rounds of division, resulting in genetic variation and the production of genetically unique cells. Cellular regeneration refers to the process of replacing damaged or lost cells, while binary fission is a type of cell division that occurs in prokaryotes.Rate this question:

A process by which gametes are produced through the combination of meiosis and other maturational changes is known as ___.
-
Gametogenesis
-
Sexual reproduction
-
Fertilization
-
Binary fission
Correct Answer
A. GametogenesisExplanation
Gametogenesis refers to the process by which gametes (sperm and eggs) are produced through the combination of meiosis and other maturational changes. This process is essential for sexual reproduction, as it ensures the formation of genetically diverse gametes that can fuse during fertilization to create offspring with unique genetic characteristics. Binary fission, on the other hand, is a form of asexual reproduction commonly observed in single-celled organisms, where the parent cell divides into two identical daughter cells. Therefore, gametogenesis is the most appropriate term to describe the process mentioned in the question.Rate this question:

A haploid cell produced during meiosis in the ovaries that disintegrates and is reabsorbed is called a(n) ___.
-
Ovum
-
Polar body
-
Spermatozoa
-
Oocyte
Correct Answer
A. Polar bodyExplanation
During meiosis in the ovaries, a diploid cell divides to produce four haploid cells called oocytes. However, only one of these oocytes develops into an ovum, while the remaining three are called polar bodies. These polar bodies are small, non-functional cells that disintegrate and are reabsorbed by the body. Therefore, the correct answer is polar body.Rate this question:

The cells in the ovaries and testes that actually go through meiosis to produce haploid cells are called ___.
-
Germ cells
-
Oocytes
-
Spermatocytes
-
Gametes
Correct Answer
A. Germ cellsExplanation
Germ cells are the cells in the ovaries and testes that undergo meiosis to produce haploid cells. Oocytes are immature eggs in the ovaries, spermatocytes are immature sperm cells in the testes, and gametes are the mature haploid cells that are produced through meiosis. However, the cells that actually go through meiosis are called germ cells.Rate this question:

Homologous chromosomes exchange information from time to time through a process called crossing over. During which stage of meiosis does this occur?
-
Prophase I
-
Metaphase II
-
Prophase II
-
Telophase I
Correct Answer
A. Prophase IExplanation
During Prophase I of meiosis, homologous chromosomes pair up and exchange genetic information through a process called crossing over. This is a crucial step in meiosis as it leads to genetic variation by shuffling genetic material between chromosomes. Prophase I is characterized by the condensation of chromosomes, formation of the spindle apparatus, and the pairing of homologous chromosomes. Therefore, Prophase I is the stage where crossing over occurs.Rate this question:

An immature ovum is called a(n) ___.
-
Oocyte
-
Spermatocyte
-
Gamete
-
Polar body
Correct Answer
A. OocyteExplanation
An immature ovum is called an oocyte. This term is used to describe an egg cell that has not yet undergone maturation and is still in the early stages of development. The other options, spermatocyte, gamete, and polar body, do not specifically refer to an immature ovum. Spermatocyte is a term used to describe a cell in the male reproductive system, gamete refers to a mature reproductive cell, and polar body is a byproduct of oocyte maturation. Therefore, oocyte is the correct answer in this context.Rate this question:

An immature spermatozoa is called a(n) ___.
-
Sperm cell
-
Gametetocyte
-
Spermatocyte
-
Polar body
Correct Answer
A. SpermatocyteExplanation
An immature spermatozoa is called a spermatocyte. Spermatocytes are the cells that undergo meiosis to produce haploid sperm cells. They are the precursor cells to mature spermatozoa.Rate this question:

Which of the following does not describe Metaphase I of meiosis?
-
The homologous chromosomes line up in the middle of the cell.
-
The homologous chromosomes pair up.
-
A metaphase plate is present.
-
Both copies of chromosome 4 line up on the same side.
Correct Answer
A. Both copies of chromosome 4 line up on the same side.Explanation
In Metaphase I of meiosis, the homologous chromosomes pair up and line up in the middle of the cell. A metaphase plate is also present during this phase. However, both copies of chromosome 4 do not line up on the same side in Metaphase I of meiosis.Rate this question:

Which of the describes Anaphase II of meiosis?
-
Sister chromatids are pulled to opposite sides of the cell.
-
Homologous chromosomes are pulled to opposite sides of the cell.
-
The nuclear membrane disintegrates.
-
A cleavage furrow forms.
Correct Answer
A. Sister chromatids are pulled to opposite sides of the cell.Explanation
Anaphase II of meiosis is the stage where sister chromatids, which are the replicated copies of chromosomes, are pulled apart and moved to opposite sides of the cell. This ensures that each resulting daughter cell receives a complete set of chromosomes. The separation of sister chromatids is facilitated by the spindle fibers that attach to the centromeres of the chromatids and pull them apart. This process is crucial for the production of genetically diverse haploid cells in meiosis.Rate this question:

Which of the following could describe either Telophase I or Telophase II?
-
A cleavage furrow forms
-
The nuclear membrane disintegrates
-
Chromosomes are pulled to opposite sides of the cell
-
The DNA is replicated
Correct Answer
A. A cleavage furrow formsExplanation
During both Telophase I and Telophase II, a cleavage furrow forms. Telophase is the final stage of both meiosis I and meiosis II, where the nuclear membrane disintegrates, and chromosomes are pulled to opposite sides of the cell. However, the formation of a cleavage furrow is a common characteristic of both Telophase I and Telophase II. The cleavage furrow is a constriction that occurs in the cell membrane, indicating the initiation of cell division. Therefore, the given answer is correct.Rate this question:

Which of the following cells is diploid?
-
A sperm cell
-
A somatic cell
-
A gamete
-
An oocyte
Correct Answer
A. A somatic cellExplanation
A somatic cell is diploid because it contains two complete sets of chromosomes, one from each parent. In contrast, a sperm cell and a gamete (such as an oocyte) are haploid, meaning they only have one set of chromosomes.Rate this question:

In humans, a ___ cell has ___ chromosomes.
-
Haploid ... 46
-
Haploid ... 23
-
Diploid ... 50
-
Diploid ... 23
Correct Answer
A. Haploid ... 23Explanation
In humans, a haploid cell has 23 chromosomes. Haploid cells are sex cells (sperm and egg) that contain half the number of chromosomes found in other body cells. This is because during the process of meiosis, the number of chromosomes is halved to ensure the correct number is restored when the sperm and egg combine during fertilization. Therefore, the correct answer is haploid ... 23.Rate this question:
