<span>The process whereby neutrophils and other white blood cells are attracted to an inflammatory site is called as <u>chemotaxis</u>. It is a process by which inflammatory cells migrated or attracted towards other cells in the blood. It's like a phenomena of negative cells attracted to positive cells. Technically speaking, it's a movement of cells in response to chemical cells. It's an important response common in cellular biology. It's also a process by which cells translate chemical information.</span>

Explain why cells regulate the synthesis of enzymes
Degger [83]

Answer:

Here's Why:

Explanation:

In living cells there are hundreds of different enzymes working together in a coordinated manner, and since cells neither synthesize nor break down more material than is required for normal metabolism and growth, precise enzyme regulation is required for turning metabolic reactions on and off.

Explain the respiratory system of a frog and the importance of "vacularization" of the skin and the mesentery
fredd [130]

 The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels. The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.

A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. The mechanism of taking air into the lungs is however sligthly different than in humans. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in.

In order to draw air into its mouth the frog lowers the floor of its mouth, which causes the throat to expand. Then the nostrils open allowing air to enter the enlarged mouth. The nostrils then close and the air in the mouth is forced into the lungs by contraction of the floor of the mouth. To elimate the carbon dioxide in the lungs the floor of the mouth moves down, drawing the air out of the lungs and into the mouth. Finally the nostrils are opened and the floor of the mouth moved up pushing the air out of the nostrils.

Frogs also have a respiratory surface on the lining of their mouth on which gas exchange takes place readily. While at rest, this process is their predominate form of breathing, only fills the lungs occasionally. This is because the lungs, which only adults have, are poorly developed.

Alexxandr [17]
What is clear here is that sedation was provided by a physician or other qualified health care professional. Read at the CPT Coding Changes For Moderate Sedation in 2017. It states there will be several codes for moderate sedation. Your statement of the case is not complete, as age is important. The codes for moderate sedation is 99151 to 99157.

A geneticist crossed pure breeding black mice with pure breeding brown mice. All the 992 mice in the F1 generation had black coa
uysha [10]

Answer:

C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele

Explanation:

Assuming the black genotype is BB and the brown genotype is bb.

At F1:

                 BB   x   bb = All Bb (black)

At F2:

                  Bb   x   Bb = BB (black), 2Bb (Black), bb (brown)

Th ratio of black to brown is 3:1

961 black : 317 brown is approximately 3:1.

Hence, the correct option is C.

<em>An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele</em>

Which of the following is an example of reproductive isolation? two populations of finches that cannot produce viable offspring
OverLord2011 [107]

The correct answer is A. Two populations of finches that cannot produce viable offspring

Explanation:

Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.
