In drosophila, proper anteroposterior and dorsoventral development requires a separate set of maternal effect gene products accu
rosijanka [135]

It is true. In drosophila, distinct sets of maternal impact gene products must accumulate in the proper region of the embryo to ensure proper anteroposterior and dorsoventral development.

<h3>What makes Drosophila unique?</h3>

The use of Drosophila over vertebrate models has many technological advantages;

  • they are simple and affordable to culture in lab settings,
  • have a significantly shorter life cycle,
  • produce huge numbers of externally deposited embryos
  • may be genetically manipulated in a variety of ways.
<h3>Why is Drosophila referred to be the genetic Cinderella?</h3>
  • Drosophila, which means "dew loving," is derived from the Greek word drósos.
  • Fruit flies, or Drosophila melanogaster, are referred to as the genetic Cinderella.
  • This term was given to them because of their 12-day lifetime, ease of culture, and ability to produce numerous offspring from a single reproduction.

.(choose all which
11111nata11111 [884]

Answer:

Myogenic mechanisms

Hormones

Sympathetic nervous system  

Explanation:

Myogenic mechanisms work in the arterioles that serve the glomerulus.

They cause the smooth muscle cells in the arterioles to contract and relax in response to blood pressure changes.

The sympathetic nervous system increases blood flow through the kidneys during resting conditions.

At times of stress, it decreases blood flow through the kidneys, making it more available to the rest of the body.

The hormones angiotensin and aldosterone regulate blood volume by controlling retention of Na⁺ and water.

C is wrong. The parasympathetic nervous system mainly controls visceral organs such as glands.
