Answer:

Option D

Explanation:

Mutations are changes that occur in the DNA sequences as a result of environmental factors like exposure to some certain chemicals or radiation that can be passed down to the offspring and this increases genetic variations which can prevent permanent fixation of an allele.

The chief force pushing water and solutes out of the blood across the filtration membrane is A) the ionic electrochemical gradie
Marysya12 [62]
<h2>C) option is correct </h2>

Explanation:

  • Glomerular filtration is the process which kidneys uses to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so that they may be eliminated from the body
  • The rate at which kidneys filter blood is called the glomerular filtration rate
  • The main driving force for the filtering process, or outward pressure is the blood pressure as it enters the glomerulus, this is counteracted to some extent by inward pressure due to the hydrostatic pressure of the fluid within the urinary space, and the pressure generated by the proteins left in the capillaries that tend to pull water back into the circulatory system (colloidal osmotic pressure)
  • The net filtration pressure is the outward pressure minus the inward pressure

Anastasy [175]
I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.

Bacteria that lack fimbriae are less likely to ________.
nikdorinn [45]

Answer:

The correct answer will be option- adhere to cell surfaces.

Explanation:

The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.  

The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.

Thus, option- adhere to cell surfaces is the correct answer.

<span>The barn owl's right ear opens slightly upward while its left ear opens slightly downward. this difference enables the owl to detect the location of a sound. It would actually depend on the location of where it would be at, and based on this, depending where it would then be located, this would then be able to differentiate where it would be located.</span>
