Biology (reproduction)

Asexual reproduction does not allow for genetic diversity or mutations, which limits the potential for the offspring to adapt to changing environments or evolve over time.

Regeneration refers to the ability of multicellular organisms to regrow or repair body parts. This process is commonly seen in organisms like starfish, where if a part of the body is broken off, it can regenerate into a new organism.

Budding is a form of asexual reproduction in both unicellular and multicellular organisms where a new organism develops as an outgrowth or bud from the parent organism.

The correct answer explains that runners and rhizomes are specific parts of plants used for reproduction and growth.

The correct way to identify the plant is by referring to a labelled diagram, which provides detailed information about its various parts.

The stamen is the male reproductive structure of the plant, with the anther responsible for producing pollen and the filament acting as the stalk of the stamen to support the anther. The incorrect answers provide inaccurate information about the functions of the stamen parts, demonstrating the importance of understanding plant anatomy.

External fertilization is a reproductive strategy where gametes are released into the external environment for fertilization to occur. This process is common among aquatic animals like fish and amphibians. While it allows for the production of a large number of offspring, the downside is that many of these offspring may not survive due to environmental hazards such as predators.

Internal fertilization involves the protection of the developing embryo within the mother's body, which increases survival chances and allows for continued care of offspring. On the other hand, external fertilization occurs outside the organism's body. Providing little to no protection to the developing embryo and lower survival rates. The number of offspring is not necessarily higher in internal fertilization, and mothers do not always die as a result of the process.

Courtship is a behavior or series of behaviors designed to attract a mate for reproductive purposes, but it does not involve actual copulation. Instead, courtship typically includes specific actions or displays to induce the female to accept the male's sperm without immediate mating.

Copulation refers specifically to sexual intercourse among animals for reproductive purposes. The term does not refer to surgical procedures, plant communication, or meditation practices.

Mitosis is a process where a single cell divides into two identical daughter cells with the same number of chromosomes as the parent cell. It is crucial for growth, development, and tissue repair in multicellular organisms.

Mitosis consists of four main stages - prophase, metaphase, anaphase, and telophase. Interphase is not a stage of mitosis but rather the phase before mitosis begins. Cytokinesis is the process of cell division following mitosis. There is no 'prophase 2' in mitosis.

Mitosis is a type of cell division that occurs in somatic cells of multicellular organisms, except for sex cells (eggs and sperm). It is essential for growth, repair, and asexual reproduction in organisms.

Mitosis is the process of cell division that produces two identical daughter cells. Sex cells need to undergo meiosis, which is a different type of cell division that produces haploid cells with half the number of chromosomes. This ensures genetic variation in offspring.

Crossing over is a phenomenon that occurs during meiosis, specifically during prophase I, not during mitosis. Crossing over plays a significant role in genetic variation.

DNA replication occurs during interphase, specifically during the S phase. Prophase, metaphase, and anaphase are stages of mitosis, not where DNA replication takes place.

In mitosis, the parent cell has 46 chromosomes, and it produces 2 daughter cells. During mitosis, the genetic material is equally divided between the two daughter cells, each having the same number of chromosomes as the parent cell.

Meiosis is a specific type of cell division that results in the production of gametes for sexual reproduction in organisms.

Meiosis is the process of cell division specifically for the production of gametes with genetic diversity. Mitosis is a process of cell division for growth and repair, while transcription is the process of creating RNA from DNA, and glycolysis is the metabolic pathway breaking down glucose for energy.

Meiosis is a type of cell division that occurs in all sex cells, which are the cells involved in sexual reproduction. It is responsible for producing gametes with half the number of chromosomes as the parent cell.

The spindle fibre is responsible for separating the chromosomes during cell division, specifically during the metaphase stage of mitosis. Centriole, flagellum, and Golgi apparatus are cellular organelles with different functions.

Crossing over, the exchange of genetic material between homologous chromosomes, occurs during Prophase 1 of meiosis.

During meiosis, the diploid cell divides into daughter cells with half the number of chromosomes, hence each daughter cell will contain 12 chromosomes.

During meiosis, the resulting gametes have half the number of chromosomes as the parent cell due to the process of chromosome reduction division.

The correct answer highlights the key differences between sexual and asexual reproduction in terms of number of parents involved, genetic variation, fertilization, involvement of gametes, and mixing of hereditary material.

Asexual reproduction involves the process of mitosis, where a single parent cell divides to produce two identical daughter cells. Sexual reproduction, on the other hand, involves the process of meiosis, where two parent cells combine genetic material to produce offspring with a unique combination of traits.
