Which is a homologous chromosome pair?
chromatid
zygote
gamete
tetrad

Answers

Answer 1
Answer:

The correct answer is option D, tetrad

Tetrad consist of two homologous chromosomes resulting into a foursome of DNA formed during meiosis. The 46 chromosomes in humans replicate during the process of meiosis. The original chromosomes and the replicated chromosome get attached to form conjoined twins, known as sister chromatids. During the prophase of meiosis, a four - part structure is formed which consists of two homologous chromosomes with two sister chromatids in each chromosomes.

Answer 2
Answer: I just took a test on this subject and the correct answer is D Tetrad.

The goals of biodiversity conservation include all of the following EXCEPT (1 point) protecting individual species. introducing exotic species into new environments. preserving habitats and ecosystems. making sure local people benefit from conservation efforts.

Answers

Introducing exotic species into new environments is not recommended for biodiversity conservation because it can cause proliferation of invasive species. This can cause ecological problems, a threat to native organisms and it can affect the economy and human health.

How do products of meiosis I differ from those of meiosis ll?

Answers

Meiosis I is dedicated to forming two Haploid(half chromosome) cells bby separating each pair of chromosomes (one of each type in each cell) and the recombination, or shuffling of genes on each chromosome with its pair by crossing over, While Meiosis II is meant to split the individual chromatids in the haploid cells to create a total or 4 daughter cells

A cell forms glycogen from simple sugars when food is plentiful. Which statement describes this process?A It is a catabolic reaction that is endothermic.
B It is an anabolic reaction that is endothermic.
C It is a catabolic reaction that is exothermic.
D It is an anabolic reaction that is exothermic.

Answers

Answer: The correct answer is-

B It is an anabolic reaction that is endothermic.

A cell forms glycogen from simple sugars when food is plentiful. In human beings, carbohydrates ( glucose) are stored in the form of glycogen in muscles and adipose tissue.

The formation of glycogen from glucose is called as glycogenesis and it requires large amount of energy ( endothermic reaction) as a larger molecule is formed from simple glucose molecules, which shows an anabolic reaction.

Thus, option B) is the right answer.

Which statement correctly distinguishes photosynthesis and respiration?Photosynthesis occurs in animal cells and not plant cells.

Cell respiration occurs in animal cells and not plant cells.

Photosynthesis uses chemical energy as energy source, and cell respiration uses light energy.

Photosynthesis uses light as energy source, and cell respiration uses chemical energy.

Answers

Correct answer: Photosynthesis uses light as energy source, and cell respiration uses chemical energy

Photosynthesis is a light dependent process in which green plants and certain other organism convert light energy in to chemical energy. In this  process sunlight is uses to to convert water and carbon dioxide into ATP molecule which are needed for growth.

Cellular respiration is metabolic process that occurs inside the mitochondria of the cell to convert biochemical energy which is derived from nutrients into ATP (Adenosine triphosphate) and removal of waste products.







Photosynthesis uses light as an energy source, while cell respiration uses chemical energy. Therefore option d. is the correct answer.

The correct statement that distinguishes photosynthesis and respiration is:

Photosynthesis uses light as an energy source, and cell respiration uses chemical energy.

In photosynthesis, plants convert light energy into chemical energy, specifically glucose. This process occurs in the chloroplasts of plant cells.

On the other hand, cell respiration is the process by which cells break down glucose to release energy in the form of ATP (adenosine triphosphate).

This process occurs in both plant and animal cells, specifically in the mitochondria.

Therefore, photosynthesis uses light as its energy source, while cell respiration uses chemical energy.

Therefore option d. is the correct answer.

The mismatch of a DNA base pair during duplication can result in a mutation.True
False

Answers

The answer is true. Mutation is the result of the mismatch of a base pair during the duplication. Mutations are neither the results from errors during the replication of DNA or other types of damage to DNA. In simpler words, DNA errs to copy accurately.
The statemnt is true. Mismach is base pairs is one of the common types of mutations, that occur. This may be due to substitution caused by purine by purine, and pyrimidine by pyrimidine. The other type is transversion, in which, purne is replaced by pyrimidine, and pyrimidine by purine.
