What makes predicting a volcanic eruption difficult?
A. Since there are so many volcanoes, and many only erupt every few hundred years, it is impossible to monitor them all at the right time.
B. All of these
C. Monitoring potential eruptions is expensive.
D. Even if magma movement is detected, it often cools underground and no eruption occurs.

Answers

Answer 1

The Factor that makes predicting a volcanic eruption difficult is : ( B ) All of these

Frequency of volcanic eruptions

Many volcanoes erupt once every one or two centuries, therefore it can be difficult to monitor all these volcanoes simultaneously, also financial constraints leads to unavailability of adequate data to monitor volcanoes, and not every magma movement leads to a volcanic eruptions as some volcanoes have one seismometer

Therefore we can conclude that The Factor that makes predicting a volcanic eruption difficult is : ( B ) All of the options listed in the question

If the optic nerve of a frog is cut and the eye is rotated 180 degrees, the frog will _______ that eye a few months later.

Answers

If the optic nerve of a frog is cut and the eye is rotated 180 degrees, the frog will have inverted vision with that eye a few months later.

The Chemoaffinity hypothesis was proposed by Roger Wolcott Sperry, and it states that the chemical signals produced by target-matching cells are differentially recognized by axons. In this manner, neurons only connect to particular cells or cell types.

Sperry concluded this hypothesis based on his experiments on the visual system of frogs. He cut the connection between the eye and optic nerve and rotated the eye 180 degrees before re-implanting it.

After a few months, it was found that the functional synapse was re-established by the regeneration of axons that were cut. He concluded that this was possible because of the neural specificity or chemical affinity between the retinal ganglionic cells and the tectum. The regeneration of the optic nerve restored the vision of that eye but it became inverted due to the rotation of the eye.

A large grassy field had a large number of moles. the first sample pulled out 129 moles. a second sample pulled out a total of 137. seventy two of them had been marked. calculate the estimated population.

Answers

The estimated population size for the given question is 246 (approx.).

When it would be impracticable to count each individual in a population, the Mark-Recapture method is utilized to make an estimate of the size of the population. The fundamental strategy entails capturing a small sample size of individuals, applying a non-lethal mark on each of them, and then releasing them back into the general population. After some time has passed, we go after another small group and keep track of how many of them have a mark. When we have a small population, the likelihood of recapturing marked individuals is higher, but when we have a huge population, the likelihood of doing so is lower. The following equation can be used to provide a mathematical expression of this idea:

N = (M*C) / R

N = Number of individuals in the population

M = number of individuals captured and then Marked

C = total number captured the second time

R = the number of individuals that were recaptured (those with a mark)

According to the given question,

M = 129

C = 137

R = 72

N = (129 X 137) / 72

If the contents of a cell have a solute concentration of 0.04 percent, which of these solutions would cause it to swell?

A.
10–percent solute concentration
B.
1–percent solute concentration
C.
0.1–percent solute concentration
D.
0.01–percent solute concentration

Answers

In osmosis phenomenon, water moves from the hypotonic solution to the hypertonic one. Option D is correct. 0.01–percent solute concentration.

What is osmosis?

Osmosis is the phenomenon that occurs when two dilutions of different concentrations are separated by a semipermeable membrane. The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.

Water tends to go from the hypotonic solution to the cell interior and keeps doing so until concentrations are equal in the cell interior and exterior.

As water enters the cell, the cell begins to enlarge and becomes bigger-sized. And because cells can not limit the amount of water moving into it, the cell keeps swelling until the membrane can not stretch anymore, and lysis occurs. It bursts.

Under natural conditions, the body regulates the extracellular fluids to avoid cells swelling until they burst.

In the exposed example, the cell have a solute concentration of 0.04 percent. For water to move into the cell, we need to find a solution with a lower solute concentration.

Among the options, the solution with 0.01 percent of solute concentration is the one that would cause water to move into the cell.

The cell content is hypertonic to the solution, and the solution is hypotonic to the cell interior.

Option D is correct. 0.01–percent solute concentration

when the kidney's own blood supply decreases, they release _ which leads to secretions of aldosterone from the adrenal cortex

Answers

When the kidney's own blood supply decreases, they release renin, which leads to secretions of aldosterone from the adrenal cortex.

Renin is an enzyme produced by certain kidney cells. It is a component of the renin-angiotensin-aldosterone system, which regulates blood pressure through a chain of reactions. Specifically, renin regulates the adrenal glands' synthesis of the hormone aldosterone.

Renin transforms angiotensinogen (a liver-produced precursor to angiotensin) into angiotensin I. Angiotensin is a hormone that causes constriction of the blood vessels.Angiotensin I is then converted to angiotensin II. Angiotensin II constricts blood vessels and promotes aldosterone release.Aldosterone helps the kidneys retain water and salt, thereby boosting the body's water content. This causes the blood pressure to rise.

For each glucose that enters glycolysis, _____ NADH enter the electron transport chain. For each glucose that enters glycolysis, _____ NADH enter the electron transport chain. 0 4 2 6 10

Answers

For each glucose that enters glycolysis, 10 NADH enter the electron transport chain.

NADH and FADH, which function as electron transporters as they move through the inner membrane region, are involved in the processes of the electron transport chain. Electrons are transferred from NADH to the electron transport chain at complex I, where they transit through the other complexes. In this mechanism, NADH is oxidized to NAD.The four protein complexes of the electron transport chain use this energy to oxidize NADH and FADH2 (ETC). Each of the three previous stages of respiration—glycolysis, the conversion of pyruvate into acetyl-CoA, and the citric acid cycle—contributes two of the ten NADH molecules that enter the electron transport. The citric acid cycle contributes six of the molecules. The citric acid cycle is where the two FADH2 come from.
