Answer:
When the sun heats water at the surface of the ocean, some of the water will evaporate and increase the concentration of salt in the water at the surface. ... This process, combined with fresh water flowing into the ocean from river and changing the salt concentration of the water, contributes to ocean currents.

what's the importance of microscope in the study of animal
Answer:
It is important because biology mainly deals with the study of cells, genes, and all organisms. Some organisms are so small that they can only be seen by using very strong magnifications, which can only be achieved by a microscope.
Which statement describes the function of nucleic acids during the synthesis of proteins ?
Answer: sheesh
Explanation cuz i said
Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
b. False
Answer:
Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
Explanation:
A woman's estrogen levels become highest towards the end of her ovulation. At this point, the woman is naturally prepared for a possible pregnancy. The occurrence of the highest estrogen levels coincides with the luteal phase, a stage of a woman's menstrual cycle, which occurs after ovulation (or the release of eggs from the ovaries), and before the start of the normal period. This luteal phase has been observed to be within 14 days for all women. By the end of the luteal phase, the corpus luteum function declines.

Explanation:
The PO2 and PCO2 of blood leaving the lungs is kept remarkably constant. This homeostasis is maintained by adjusting the magnitude, or volume, of respiration. Thus, it follows that changes in the magnitude of respiration are influenced by changes in P_O2 and P_CO2 in the body.
Of these two gases, changes in ____(1)___ are the most important in regulating the magnitude of ventilation. A rise in the partial pressure of this gas triggers the body to __(2)____ the magnitude of ventilation. Which of the following statements correctly describes the major mechanism by which this has is monitored?
(1) PO2 or PCO2
(2) decrease or increase
A. Peripheral chemoreceptors in the carotid arteries monitor changes to CO_2 levels in the arterial blood.
B. Peripheral chemoreceptors in the carotid arteries monitor changes to P_CO2 levels in the arterial blood.
C. Central chemoreceptors in the medulla monitor changes to H^+ levels in the extracellular fluid
D. Central chemoreceptors in the medulla monitor changes to CO_2 levels in the extracellular fluid.
Answer:
1. Partial pressure of Carbon dioxide or PCO₂
2. A rise innthe partial pressure of Carbon dioxide triggers the body to increase the magnitude of ventilation.
A. Peripheral chemoreceptors in the carotid arteries monitor changes to CO2 levels in the arterial blood.
Explanation:
Breathing or ventilation refers to the process by which the gases oxygen and carbon dioxide are exchanged in the body through the lungs.
The most important function of breathing is to supply oxygen to the body as well as the removal of the the carbon dioxide produced in the body during respiration. Since oxygen and carbon dioxide are both gases, their concentration in the lungs are given as their partial pressures. The partial pressure of carbon dioxide (PCO2) in the lungs, or its concentration in the body, controls the magnitude or rate of respiration.
The peripheral chemoreceptors located in the carotid arteries detect and monitor changes in the levels of carbon dioxide in the arterial blood. An increase in arterial levels of CO2 when detected, is passed as signals from the peripheral chemoreceptors along nerves to the respiratory groups of the respiratory center, which then induces an increase in the movement of the respiratory muscles especially the diaphragm. Thus, respiration rate is incresed to remove CO2 and bring in oxygen.
What type of macromolecule would be responsible for giving a child brown eyes when both of his parents have blue eyes?

Why do plant cells need a cell wall and chloroplasts but animal cells do not?
Answer:
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . ... So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.
