<h2>(c) is Right Answer</h2>

Explanation:

    (c) is Right Answer.

  1. A<em> </em>repressor is a DNA-or RNA-restricting protein that restrains the outflow of at least one qualities by authoritative to the operator or associated silencers.
  2. A RNA-restricting repressor ties to the mRNA and forestalls interpretation of the mRNA into protein. This hindering of articulation is called repression.
  3. Transcribing a gene, RNA polymerase ties to the DNA of the quality at an area called the promoter.
  4. It contains acknowledgment locales for RNA polymerase or its aide proteins to tie to.
  5. The DNA opens up in the advertiser district with the goal that RNA <em>polymerase can start translation.  </em>
  6. Interpretation factors are an exceptionally assorted group of proteins and by and large capacity in multi-subunit protein edifices.
  7. They may tie legitimately to <em>uncommon “promoter” locales of DNA, </em>which lie upstream of the coding area in a <em>quality, or straightforwardly to the RNA polymerase atom.</em>

How did Darwin arrive at the idea about species variation
jeyben [28]

Answer:

We can see some of the most important patterns Darwin noticed in distribution of organisms by looking at his observations of the Galápagos Islands off the coast of Ecuador. Darwin found that nearby islands in the Galápagos had similar but nonidentical species of finches living on them.

arsen [322]

Answer:

Explanation:

The more similar the two species are, the more their niche overlaps and the more competition there is.

<em>The most interesting results obtained in animal models of passive immunotherapies developed according to the “amyloid-beta cascade hypothesis” and the “Tau hypothesis” are monoclonal antibodies that directly or indirectly target Aβ plaques or neurofibrillary tangles. Unfortunately, these therapeutic antibodies cannot replicate their promising effects on humans at the clinical phase. Despite this, we still hope to learn from these failures and to explore new pathways. The great effects obtained in animals with passive immunotherapy suggest that this technology may be an important key to curative treatment. The remaining challenge is to find a way to achieve the same encouraging results for humans. Alzheimacy expects to join hands with global partners to focus on the development of therapeutic antibodies for Alzheimer’s disease (AD) and continue to fight against this disease.</em>

Answer:

It is called feedback regulation.

Explanation:

It is used when a product of the reaction is used for regulate the reaction. Therefore when there is enough product like ATP in this situtation, there is no need to run the reaction.

Dietary fats, specifically cholesterol, have been given a bad image in the popular media; however, they are essential for energy
Maslowich

Dietary fats are necessary for providing energy to your body and supporting cell activity. They also aid in the protection of your organs and the preservation of your body's heat. Fats aid in the absorption of certain nutrients and the production of key hormones.

<h3>What is cholesterol?</h3>

Cholesterol is a waxy, fat-like molecule found in all of your body's cells. Cholesterol is required by your body for the production of hormones, vitamin D, and chemicals that aid digestion. Your body produces all of the cholesterol that it requires.

Fatty acids provide an ideal anisotropic solution for other membrane constituents due to their existence in bilayer membranes. They give the membrane bilayer fluidity, allowing membrane-bound receptors, enzymes, and other proteins to diffuse laterally along the bilayer membrane's surface.
