Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area.The loss of biodiversity has two significant impacts on human health and the spread of disease. First, it increases the number of disease carrying animals in local populations. ... At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease carrying species.Participating in Biodiversity Conservation. Identify locations of critical wildlife habitat for species at risk and the threats to these areas. ... Keep vehicles on main roads to reduce the spread of weeds and disturbance to wildlife. Monitor and assess your pets' impact on biodiversity.

Answer:
The number of liters, or amount of blood that circulates through all the systems of the human body is always a constant one. However, how much of the total amount of blood in the human body passes through the two major circuits (systemic and pulmonary) depends not just on the volume of blood, but also on other factors such as the size of the vessels through which the blood flows and the amount of muscular layers, or any form of tissue, that will offer resistance to that flow. Because pulmonary vessels are smaller in size, and because the need for speed in flow in that circuit is not paramount, as its purpose is to load oxygen and unload CO2 to the lungs, the mean pressure is smaller thain in the systemic flow.
Using, however, the equation on the question, to prove that mean pulmonary blood pressure is 5 times less than that of systemic blood pressure, we would have the following:
1. F= pressure/ systemic resistance
2. Flow= pulmonary flow.
3. Systemic resistance = 5x pulmonary resistance
4. Systemic pressure/ systemic resistance = pulmonary pressure/ pulmonary resistance.
5. Systemic presure x pulmonary resistance/ (5x pulmonary resistance) = Pulmonary pressure.
6. Pulmonary pressure= systemic pressure/5
Answer:
d) passage of a solute against its concentration gradient
Explanation:
When a solute is transported against its concentration gradient, the cells use metabolic energy. To move a substance from the region of its lower concentration to that of its higher concentration, the energy of ATP hydrolysis is utilized. These types of transport mechanisms are called active transports. If ATP hydrolysis is inhibited in a cell, it would not be able to perform the uphill movement of solutes due to the lack of any source of energy to drive the process.
