Answer:

The correct answer is option A, Blood pressure would drop during a heartbeat

Explanation:

When the arteries get constrict, the walls of arteries reduces  the space/volume  with in the arteries which causes blockage for a very minute time period. When the flow is blocked the blood pressure increases, while when the walls are released the pressure reduces but the flow increase.  

This process is also refered to as Vasoconstriction and it is a normal process which stabilizes the blood pressure.

agasfer [191]

Answer:

The options

A)Damage to cellular mitochondria

B)Increased ATP levels

C)Activation of the p53 protein

D)Apoptosis

The CORRECT ANSWER IS D

D)Apoptosis

Explanation:

The extrinsic pathway of apoptosis includes extracellular signaling proteins which adhere to cell surface molecules known aa death receptors which in turn activates apoptosis.

The aftermath activates endonucleases prompting division of DNA and ultimately cell death.

Apart from the TNF and Fas ligand, primary signaling molecules also promotes the extrinsic pathway, examples of such are the TNF-related apoptosis-inducing ligand (TRAIL); the cytokineinterleukin-1 (IL-1); and lipopolysaccharide (LPS), the endotoxin located in the outer cell membrane of gram-negative bacteria while the activation of the p53 protein, and decreased ATP levels in the intrinsic pathway results in DNA damage.

There are multiple lines of evidence that provide support for common ancestry and evolution. Write 3-4 paragraphs describing at
Colt1911 [192]

Though I cannot write this essay for you, I can provide some information to get you started on the relationship between ancestry and evolution.

<h3 /><h3>How are ancestry and evolution related?</h3>

Ancestry and evolution share a close relationship in that we can use one to learn about the other. Evolution can be <u>traced </u>using ancestry. By analyzing the genetic information of ancestral species and using information gathered about the environment in which they lived, we can deduce the impact of evolution on said species. One possible example is that penguins used to be capable of flight, but given their mostly aquatic environments, have evolved wings more suited for swimming, and lost the ability to fly as a result.

Therefore, we can say that ancestry and genetic information can be used to support the theory of evolution by examining how two species can be very different but share a common ancestor, and evolution can explain these changes.
