Euglena are protists that move by means of flagella, and they contain chloroplasts and an eye spot or light receptor. They are c

apable of ingesting food by phagocytosis. Being simple organisms, they can reproduce asexually.
Under what environmental condition would we expect euglena to ingest food rather than produce food via photosynthesis?

A) when light is limited
B) when light is abundant
Eliminate
C) when oxygen is limited
D) when temperatures drop

Discuss and explain the correlation between thirst and kidney function​
Pachacha [2.7K]

The correlation between thirst and kidney function is the following:

Thirst is the regulator of the state of hydration, necessary to eliminate the osmotic load, it can help preserve kidney function.

The instantaneous perception of osmolarity in the blood allows us to generate the sensation of thirst.

In other words, this sensation is in turn caused by a high concentration of osmolytes (compounds that affect osmosis, or the way it is measured, osmolality or osmolarity) or by hypovolemia.

The receptors that control cellular dehydration are called osmoreceptors and are located in the lateral preoptic area.

Osmoreceptors detect this decrease in cellular water and trigger thirst, as well as the release of Anti-Diuretic Hormone into the bloodstream.

Antidiuretic hormone helps regulate the amount of water in the body by controlling the amount of water excreted by the kidneys.

Therefore, we can conclude that the sensation of thirst appears the sodium concentration is higher than normal, when drinking water, the concentration gradient is reduced, which allows the normal functioning of kidney function.

Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you
den301095 [7]

Answer:

There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

Marissa is testing a hypothesis through experimentation. She believes that immersing ocean coral in carbonic acid will slow the
motikmotik

Answer:

The answer choices to this question are:

A) She releases cement particles into a random number of the coral samples.

B) She uses three different types of coral to establish her dependent variables.

C) She treats the coral samples identically with varying levels of carbonic acid.

D) She obtains her coral samples from coral reefs surrounding different continents.

Best Answer is:

A) She releases cement particles into a random number of the coral samples.

Theory:

It has been researched that ocean acidification caused by carbon dioxide emissions causes a decrement in the coral reef growth and this will keep slowing down unless steep and rapid reductions in greenhouse gas emissions are made. And the Coral reefs offered economic opportunities would advantage the surrounding communities from fishing and tourism.

i did this question so thats why i know the answer choices

hope this helpsss
