Chart that tracks which members of a family have a particular trait
Correct Answer
A. Pedigree
Explanation
A pedigree is a chart that tracks which members of a family have a particular trait. It is commonly used in genetics to study the inheritance patterns of traits or genetic disorders within a family. By mapping out the presence or absence of a trait across multiple generations, a pedigree can provide valuable information about the mode of inheritance and help identify individuals who may be at risk for inheriting or passing on a specific trait or disorder.
2.
If a parent has type A blood, the other parent has type B bloodwhat are the possible blood types of the baby?
Correct Answer
D. All of the above
Explanation
If one parent has type A blood and the other parent has type B blood, the possible blood types of the baby could be AB-, A, or B. This is because the baby can inherit either the A allele from the type A parent, the B allele from the type B parent, or both alleles (AB) if both parents pass on their respective alleles. Therefore, all of the above blood types are possible for the baby.
3.
Where are sex linked jeans located
Correct Answer
B. Chromosomes
Explanation
Sex-linked genes are located on chromosomes. Chromosomes are thread-like structures found in the nucleus of cells that carry genetic information. They contain genes, which are segments of DNA that determine specific traits. Sex-linked genes are genes that are located on the sex chromosomes, specifically the X and Y chromosomes. These genes can be responsible for traits or disorders that are more commonly seen in one sex than the other. Therefore, it is correct to say that sex-linked genes are located on chromosomes.
4.
What symbol is a male on a pedigree?
Correct Answer
C. Square
Explanation
In a pedigree, a square symbol represents a male individual. This symbol is commonly used to indicate the gender of an individual in a family tree diagram. The square shape is chosen to differentiate males from females, who are typically represented by a circle symbol. Therefore, the correct answer is square.
5.
An organisms particular role in an ecosystem- how it makes its living....
Correct Answer
B. Niche
Explanation
The correct answer is "niche." In ecology, a niche refers to an organism's specific role or position within an ecosystem. It encompasses how the organism interacts with its environment, including its habitat, food sources, and interactions with other species. An organism's niche determines how it obtains resources, survives, and reproduces within its ecosystem.
6.
Most consisten biome, lots of rain
Correct Answer
B. Rainforest
Explanation
The correct answer is rainforest because rainforests are known to be the most consistent biome with a high amount of rainfall. Rainforests receive a significant amount of precipitation throughout the year, which creates a consistently wet and humid environment. This abundant rainfall supports the growth of diverse plant and animal species, making rainforests one of the most biologically rich and diverse ecosystems on Earth.
7.
Put these in order from simple to complex in an ecosystemorganism, ecosystem, population, community
Correct Answer
organism, population, community, ecosystem, organism population community ecosystem, organism,population,community,ecosystem
Explanation
In an ecosystem, the basic unit is an organism, which refers to an individual living thing. Multiple organisms of the same species make up a population, which is the next level of organization. Populations of different species interacting with each other form a community. Finally, all the communities in a specific area, along with the non-living factors, make up an ecosystem. Therefore, the correct order from simple to complex in an ecosystem is organism, population, community, ecosystem.
8.
Cold/driest, treeless, land of midnight sun
Correct Answer
C. Tundra
Explanation
The given answer, tundra, accurately describes the characteristics mentioned in the question. Tundra is known for its cold and dry climate, lacking trees, and experiencing the phenomenon of the midnight sun. This biome is characterized by low temperatures, short growing seasons, and a lack of trees due to the harsh conditions. Therefore, tundra is the correct answer based on the provided information.
9.
What is mutation
Correct Answer
B. Tumor
Explanation
The term "mutation" refers to a change in the DNA sequence of an organism. In this context, a tumor is an abnormal growth of cells that can be caused by mutations in the DNA. Therefore, the answer "tumor" is the most relevant option as it directly relates to the concept of mutation.
10.
Competition can be reduced when there is enough.....
Correct Answer
B. Food
Explanation
Competition can be reduced when there is enough food because when there is an abundance of food, individuals have access to the necessary nutrients and energy to survive and thrive. This reduces the need for individuals to compete with each other for limited resources, as there is enough food available for everyone. With ample food supply, individuals can focus on other aspects of survival and reproduction, leading to a decrease in competition for food resources.
11.
What advantage does specialized cells have over others?
Correct Answer
B. Unique function
Explanation
Specialized cells have an advantage over others because they have a unique function. This means that they are specifically designed to perform a specific task or carry out a particular function in the body. This specialization allows them to be more efficient and effective in performing their designated role, compared to cells that have a more general or generic function. By having a unique function, specialized cells can contribute to the overall functioning and health of the organism in a more specialized and targeted manner.
12.
Tiny hairlike structure that help cells move
Correct Answer
A. Cilia
Explanation
Cilia are tiny hairlike structures that help cells move. They are found on the surface of many types of cells and are involved in various functions such as moving fluid, sensing the environment, and facilitating the movement of reproductive cells. Cilia have a characteristic structure and motion that enables them to beat in a coordinated manner, propelling the cell or moving substances across the cell surface. Flagella, on the other hand, are similar to cilia but are longer and typically found singly or in pairs, helping cells move in a whip-like motion.
13.
Has a whip like tail, cells have only one maybe 2
Correct Answer
B. Flagella
Explanation
The correct answer is flagella because flagella are whip-like tails that certain cells have. These flagella help the cells in movement and propulsion. Unlike cilia, which are shorter and more numerous, cells usually have only one or maybe two flagella. Therefore, flagella is the most suitable answer based on the given information.
14.
Two functions of the nucleus
Correct Answer
D. Control center and make ribosomes
Explanation
The nucleus serves as the control center of the cell, regulating various cellular activities. It contains the cell's genetic material, DNA, which controls the synthesis of proteins through the production of ribosomes. Ribosomes are responsible for protein synthesis, and they are made in the nucleus before being transported to the cytoplasm. Therefore, the two functions of the nucleus mentioned in the answer are accurate: serving as the control center and producing ribosomes.
15.
Chromosomes are.... (click all)
Correct Answer(s)
A. Red
C. Structure carrying genes
Explanation
Chromosomes are not red or blue, so those options can be eliminated. Chromosomes are the structures that carry genes, which is the correct answer provided. There is no mention of chromosomes carrying ribosomes in the given options.
16.
Male sex cell
Correct Answer
A. Sperm
Explanation
Sperm is the correct answer because it is the male sex cell responsible for fertilization. Sperm is produced in the testes and is released during ejaculation. It has a tail that helps it swim towards the egg for fertilization to occur. On the other hand, an egg is the female sex cell and is produced in the ovaries. Fertilization occurs when a sperm penetrates the egg, resulting in the formation of a zygote.
17.
Female sex cell
Correct Answer
B. Egg
Explanation
The female sex cell is called an egg. It is produced in the ovaries and is necessary for sexual reproduction. When fertilized by a sperm, the egg develops into an embryo and eventually a fetus. The egg contains genetic material from the mother and provides the necessary nutrients for the early stages of development. Therefore, the answer to the question "female sex cell" is egg.
