Answer:

A. iron level of the blood

Explanation:

All of the other properties are physical properties that can be detected by vibrations picked up by the stethoscope. The chemical property, iron level, will not necessarily be detected by the stethoscope but may contribute to poor cardiac health.

Will a wound will take a longer time to heal if an individual is lack of carbohydrate?
mezya [45]

Answer:

Carbohydrates Role in the body:

Glucose is necessary in wound healing for a number of reasons. These include: Providing energy for leucocytes and macrophages (white blood cells). Stimulates fibroblast growth etc

Wound healing implicates several biological and molecular events, such as coagulation, inflammation, migration-proliferation, and remodeling. Here, we provide an overview of the effects of malnutrition and specific nutrients on this process, focusing on the beneficial effects of curcumin. We have summarized that protein loss may negatively affect the whole immune process, while adequate intake of carbohydrates is necessary for fibroblast migration during the proliferative phase.

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

<h3><u>Gene A</u></h3>

AA x Aa

  • F1 genotypes: 1/2 AA, 1/2 Aa
  • F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>

BB x bb

  • F1 genotypes: 1 Bb
  • F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>

Cc x Cc

  • F1 genotypes:  1/4 CC, 2/4 Cc, 1/4 cc
  • F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:

<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>

Prostaglandins: A. stimulate smooth muscle contraction. B. have four-membered rings and are derived from arachidonic acid. C. ar
nevsk [136]

Answer:

The correct answer is option A, that is, stimulate smooth muscle contraction.

Explanation:

A group of lipids and a hormone that plays an essential role in monitoring the process of the formation of blood clots, stimulation of labor, the flow of blood and inflammation is known as prostaglandins. The hormone prostaglandin takes part in various kinds of body functions like the relaxation and contraction of the smooth muscles at the time of childbirth, monitoring blood pressure, dilation and constriction of blood vessels, and produce inflammation at the site of infection or tissue damage.  

Prostaglandins possess five-membered rings and are obtained from the fatty acid, arachidonic acid. At the time of blood vessel injury, thromboxane, that is, a form of prostaglandin enhances the process of blood clot formation so that the injury site gets heal quickly.
