Answer: The correct answer is -

D) They have the same number of chromosomes.

Gametes can be described as reproductive cells or sex cells that are haploid ( that is having half the number of chromosomes from their diploid parent cell).

They are produced through a process of cell division, which is known as meiosis (also called reductional cell division). During this process, a diploid parent cell undergoes two rounds of cell division (meiosis I and meosis II) to produce four haploid, daughter cells (called gametes, such as egg produced females).

The haploid gametes all have the same number of chromosomes, which is 23 chromosome in case of human beings.

Thus, option D) is the right answer.

Firdavs [7]

Answer:

B) Multicellular Simple gland

Explanation:

Exocrine Glands:Glands that secrete their products onto the apical(or epithelia) surface directly or via epithelial ducts or tubes that are connected to the apical surface. These Exocrine glands are composed of highly specialized epithelial cells..

Exocrine glands can either be branched or Unbranched based on the arrangement.

*Multicellular simple glands*:Glands that have an *unbranched duct* into which cells secrete. Each secretory portion empties separately on an epithelial surface.

Which of the following has the most potential of experiencing background extinction based on the natural disruption described?

Neko [114]

The option that has the most potential of experiencing background extinction based on the natural disruption is : ( C ) A species that will not grow during a specific season every year

<h3>What is Background extinction </h3>

Background extinction is the gradual extinction of species due certian environmental factors such as change in weather conditions, disease, competitive disadvantage and habitat loss.

A population that will not grow during a specific season every year will experiences a gradual extinction process while other options will experience a fast and sudden extinction process.

Hence we can conclude that the most potential of experiencing background extinction based on the natural disruption is : A species that will not grow during a specific season every year.
