Vascular plants help maintain the water cycle. Which property of these plants enables them to carry out this function?

1 answer:

4 0

A.)Well–developed vascular system
Vascular plants help maintain the water cycle. The property of these plants enables them to carry out this function is their well-developed vascular system. These type of plants are more evolved and developed than nonvascular plants because of its specialized characteristics like xylem, which is a tissue that is responsible for its framework and not only that, it is also has a greater mechanism for water transference. Another is phloem, which is responsible for food conduction.

Answer:

Atherosclerosis would be the occlusion.

What anastamosis is maintaining blood supply to the brain and by what routes?

●Collateral Circulation

●Collateral Willis

Explanation:

Atherosclerosisis affects arterial blood vessels by causing a thickening of the arteries by multiple plaques within the arteries.

Collateral Circulation best shows why there was adequate and necessary blood flow to the brain.

In Collateral Circulation closed smaller arteries links and connect to two bigger arteries or certain points of the same artery acting as another way of blood supply.

Collateral vessels are often closed but in people with coronary heart disease or stroke, it will expand and increase.

Note: there is something called collateral Willis referring to the choice of it remain close in some people and being open in some people.

Answer: A Fixed Action Pattern

Explanation:

A fixed action pattern is an ethological term and off course a natural activity pattern that causes animals to act in a specific behavior pattern distinctive to their species. It is a pattern that is relatively unchangeable within the species and usually ends even when it is interrupted. You can say that, it is innate releasing mechanism or network where sign stimulus exists, once released from neural network; fixed action pattern leads to completion as well.

What affect does binding a gas to a hemoglobin have on homeostasis

frutty [35]

Explanation:

Haemoglobin acts as a protein buffer.

Haemoglobin- oxygen binding in the blood is part of acid-base homeostasis. The cells within the brain or CNS ensure that more oxygen is taken into the lungs at a faster rate while carbon dioxide is removed; this aids in gaseous exchange and maintaining the pH of the blood- oxygen concentrations are kept high within the blood stream as blood circulates through the body.

Blood pH levels are typically within 7.35 --7.45. it is regulated by coordinated activity controlled by the brain, and carried out by the kidneys and lungs; along with red blood cells. When the body needs more oxygen, CO2 (as waste from cellular respiration), in the blood is converted to biarbonate increasing acidity; at the same time, H released in the reaction, and buffered by haemoglobin.

-The haemoglobin undergoes reduction by oxygen, and the pH level is maintained.

Further Explanation:

A typical oxygen disassociation curve shows haemoglobin’s percentage saturation at different oxygen concentrations (partial pressures). This shows the equilibrium between oxyhaemoglobin (haemoglobin in its oxygen bound state and haemoglobin (free of oxygen molecules). The saturation generally increases with increased partial pressures of oxygen.

Haemoglobin is an oxygen binding protein comprising four iron-based peptide subunits: two α subunits and two β subunits. Each molecule of haemoglobin has the ability to bind up to four oxygen molecules at a time; this occurs via cooperative binding- meaning that with increased haemoglobin- oxygen binding at the protein haemoglobin’s subunits,(where oxygen is a ligand) there is an increase in its affinity for oxygen.

This is because there is a conformational change in the hemoglobin molecule due to the altered orientation of the protein’s secondary structures, making it easier for a second molecule of oxygen to successively followed by more O2-Haem binding until the molecule is saturated- at this point the curve plateaus- it reached its carrying limit.

Hormones bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis. It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions.

Answer:

The difference between mitosis and meiosis is that....

Mitosis produces two daughter cells with the same number of chromosomes as the parent cell. 

Meiosis results in four daughter cells harboring only half of their parent's chromosomes, which underwent recombination.
