Alien species often displace native species because alien species _____.

Answers

The answer is they outcompete native species. When the exotic species are being introduce, the species then can grow at a high rate due to lack of predators as well as competitors thus eventually may replace the native species then.

If a tornado destroys a deciduous forest, what kind of succession follows?

Answers

The correct answer of the given question above would be SECONDARY SUCCESSION. If a tornado destroys a deciduous forest, the kind of succession that follows is called a secondary succession. Secondary succession is defined as process which is started by a specific event, whether it is a hurricane, tornado or fire, that decreases the already established ecosystem. Hope this answer helps.

The correct answer is D.) Second Sucession.

Explain why DNA has an overall negative charge.

Answers

DNA has an overall negative charge because DNA backbones are made of deoxyribose and pentose sugar which are connected in phosphodiester bond. The groups of phosphate usually have a negative charge that makes positively charged particles (histone proteins) to interact and form chromatin.

Aldosterone exerts effects on principal cells of the kidney by causing:A. increased levels of cAMP and increases in the total number of Na+ channels.
B. decreased levels of cAMP and decreases in the number of open K+ channels.
C. increased numbers of Na+/K+ pumps. decreased numbers of Na+/K+ pumps.

Answers

Answer: Option C.

Increased numbers of Na+/K+ pumps. Decreased numbers of Na+/K+ pumps.

Explanation:

Aldosterone is a steroid hormone produced by the zona glomerulosa of the adrenal cortex.

It activates sodium and potassium channels in the principal cells of distal tubules, collecting ducts. It acts as electrolytes in the distal tubules. It increase sodium reabsorption from the urine, sweat and duct.

Answer:

Acting on the mineralocorticoid (MR) receptors of the main cells in the distal convoluted tubule, which increases the permeability in its luminal apical membrane to potassium and sodium and activates the basolateral Na + / K + pumps, stimulating the hydrolysis of ATP that leads to phosphorylation of the pump, causing a conformational change in this membrane protein. The phosphorylated form of the pump has a low affinity for Na + ions, thereby expelling them into the extracellular space between each epithelial cell in the tubule. This will lead to reabsorption of these ions (and the water they carry) into the adjacent blood capillaries, thus concentrating the concentration of Na + in the blood. Similarly, the concentration of K + (potassium) ions in the extracellular space (which is precisely one of the signals collected by Aldosterone secretion); This means an intracellular K + increase, for which potassium channels are opened mainly in the apical region of the cell membrane, excreting this ion towards the luminal area of the tubule, where it will be incorporated into the urine. (Chloride anions are also reabsorbed in conjunction with sodium cations to maintain the electrochemical balance of the system.)

Aldosterone stimulates H + secretion by cells interspersed in the collecting tubule, regulating plasma levels of bicarbonate (HCO3−) and its acid-base balance.

Explanation:

Aldosterone is one of the most important pillars of the renin angiotensin aldosterone system, in this way we are saying that it is part of one of the regulators of blood pressure.

When blood pressure decreases, the blood vessel proprioceptors capture the drop in pressure and thereby activate the presence of aldosterone in the body.

Aldosterone is a mineralocorticoid that generates an increase in sodium in the lumen of vessels by dragging masses of water. By dragging water due to a difference in concentrations of said ion, the blood vessel volume increases.

By increasing the blood volume of the vessel, it generates more pressure on the walls and therefore increases the blood pressure, compensating for the hypovolemia for which this route began.
