Answers

Answer:

proximal tubule

Explanation:

Glucose reabsorption takes place in the proximal tubule of the nephron, a tube leading out of Bowman's capsule. The cells that line the proximal tubule recapture valuable molecules, including glucose.Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.

Explain how the body prevents particles in inspired air from reaching the gas
exchange surfaces.

Answers

Your respiratory system prevents harmful substances from entering the lungs by using: .Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean

Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.

What is inspired air?

Due to exchanges that occur in the alveoli, the amount of gases in the air that is breathed in and out varies. We only take in about 4 to 5 percent of the oxygen found in atmospheric air, and we exhale air with about 16% oxygen.

Normal air contains about 0.04% carbon dioxide, and as it diffuses from the blood into the alveoli, we exhale air with about 4% carbon dioxide. Exhaled air is hotter than that which we breathe in and includes more water vapor than that which we breathe in.

In contrast to ordinary smell, which occurs during the inhalation phase, the olfactory contribution to flavor occurs during the exhalation process. As a result, we can conclude that expired air differs from inspired air in terms of oxygen content, bacterial density, and water vapor content.

Therefore, Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.

According to the National
Institute of Health, ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. A few beats of ventricular tachycardia often doesn't cause
problems. However, episodes that last for more than a few seconds can be dangerous. Ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation.
Based on the passage above, how will prolonged ventricular tachycardia affect blood pressure?
O It will increase blood pressure because the ventricles are contracting with more force.
O It will increase blood pressure because the ventricles are filling with more blood between beats.
O It will decrease blood pressure because there is a longer rest period beats of the ventricles.
O It will decrease blood pressure because the ventricles are filling with less blood between beats.

Answers

Answer:

It will decrease blood pressure because the ventricles are filling with less blood between beats.

Explanation:

In ventricular tachycardia, the heart beats faster than normal, usually 100 or ... The chaotic heartbeats prevent the heart chambers from properly filling with blood. As a result, your heart may not be able to pump enough blood to your body

This fossil turtle and this living hawk both have a structure in their neck called the atlas bone. What best explains why both species have an atlas bone?

b) The turtle and hawk both share the same ancestor population that had an atlas bone. They inherited this structure from the ancestor population.

c) It is impossible to say. Fossils are very old; therefore, we cannot make observations of the turtle’s ancestors, and we cannot explain its body structures.

Which statement is true about a species living in a homogenous environment compared to a species living in a heterogeneous environment? A species that lives in a homogeneous environment is more likely to exhibit phenotypic plasticity. The homogeneity or heterogeneity of an environment does not determine whether a species will exhibit phenotypic plasticity. Only a large population in a homogeneous habitat can exhibit phenotypic plasticity. A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.

Answers

Answer:

A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.

Explanation:

Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.

Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.

Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.

A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.

Answers

Answer:

4.A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.

Explanation:

It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.

Let the total number employees be e.

Three fourth of the total employees is e, the total number of employees at the meeting were less than 24.

e < 24

Multiply 4 both sides.

ex 4 < 24×4

3e < 96

Divide both sides by 3.

e < 32

Therefore the value of e is less than 32.

In a number line as we approach towards left the the value of integers decreases.

Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.

Since 32 is not included in the solution set, therefore there is an open circle on 32.
