Large vacuole

Explanation:

I think if not im sorry!!

Answer:

A centriole

Explanation:

is a small set of microtubules arranged in a specific way. There are nine groups of microtubules. When two centrioles are found next to each other, they are usually at right angles. The centrioles are found in pairs and move towards the poles (opposite ends) of the nucleus when it is time for cell division.

Answer:

C.) The variable that is observed or measured by the experimenter.

Explanation:

The dependent variable is the variable that is being measured or tested in an experiment.

For example:
In a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores, since that is being measured.

Answer:

Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. ... The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

Answer:

Low absorption of nutrients into the bloodstream from digested food.

Explanation:

This question is regarding the small intestine of a cow, which is said to be similar in general structure and function to the small intestines of humans. The small intestine is an organ found in the digestive tract of the cow or human in this case. Its primary function is to absorb the nutrients from the food, that has undergone series of digestion, into the bloodstream.

The small intestine is able to do this with the aid of the finger-looking extensions found on its wall called VILLI. The villi further contains MICROVILLI, which together helps the small intestine absorb nutrients into the blood. Hence, in a case whereby damage in the wall of the small intestine of the cow reduces the number of villi, resulting in weight loss and weakness.

This damage to the intestinal wall will cause a disruption in the absorptive function of the small intestine due to the reduced number of villi. Therefore, THE INABILITY OR LOW ABSORPTION OF NUTRIENTS INTO THE BLOOD THAT THE DAMAGE CAUSES is responsible for the weight loss and weakness in the cow.

The reason for the weight loss and weakness is as a result of decreased

absorption of nutrients from digested food.

The villi is a finger-like structure found in the small intestine which helps in

the absorption of nutrients from digested food into the bloodstream. When

the villi are reduced, the absorption of nutrients are reduced.

This thereby brings about weight loss as a result of nutrient deficiency

caused  by low absorption into the bloodstream of the animal(cow)

Answer:

The statement "It is a waste of product of photosynthesis" is incorrect about the role of glucose.

Answer:

They must also be able to gather energy through photosynthesis.

Explanation:

Some algae are considered protists and have photosynthetic pigments in the body, such as certain species of Chlorela, Chlorogonium, Euglena and Navicula are able to grow normally in the dark or in a carbon-deficient environment provided they are supplied with substances. high energy and easily metabolizable chemicals such as fatty acids, acetates, carbohydrates, etc.

For this reason, we can say that Euglena and several other protists, as well as plants, must also be able to collect energy through photosynthesis.

Answer:they must also be able to gather energy through photosynthesis

Explanation:

Answer:

The global conveyor belt's circulation is the result of two simultaneous processes: warm surface currents carrying less dense water away from the Equator toward the poles, and cold deep ocean currents carrying denser water away from the poles toward the Equator.

Answer:

Aerobic respiration and photosynthesis are both part of a cyclic process of biochemical reactions. Photosynthesis requires the products of aerobic respiration (carbon dioxide and water), while aerobic respiration requires the products of photosynthesis (glucose and oxygen).

Crown me as brainliest:).

Answer:

1) In cellular respiration, water and carbon dioxide are products. According to the graph, the products have a lower energy level than their reactant counterparts. - ANSWER IS C

2)

3)

4) Cellular respiration releases carbon dioxide into the atmosphere. - ANSWER IS B

5) Anna is correct that all cellular processes that require energy require ATP, but those that do not require energy occur without ATP. However, the process of glycolysis requires the input of ATP energy.

For each cell of the body to perform its normal cell functions, ATP is the primary energy-driving molecule that must be present in the cell. As a result, ATP is referred to as the "energy currency" of the cell.

However, there may be some processes that do not necessitate the use of energy. Diffusion, osmosis, and other processes that occur along a concentration gradient are examples of such processes.

ATP is required for the processes of glycolysis and the Krebs’s Cycle. - ANSWER IS B

I hope this at least gets you a good start. I am still working on the other two answers, but had something come up that I needed to do. So I will be back with the other two answers in a bit!

Answer:

Ammonia, nitrite and nitrate at higher levels are toxic to fishes in the aquarium.

Explanation:

Ammonia,nitrates and nitrites are all byproducts gotten from organic wastes which is biodegraded in the aquarium. These byproducts are gotten from fish and plant wastes, uneaten algae , bacteria e.t.c. There are bacterias in the aquarium that help to break down nitrogenous wastes in the aquarium.

Therefore, the waste from fish and plants are breakdown by bacteria into ammonia.

Ammonia at high levels are very toxic to fishes. Then the nitrifying bacteria then help to convert ammonia to nitrite.

Nitrite also at high levels is very toxic to fishes in the aquarium.

Nitrite is also converted to nitrate by nitrifying bacteria.

Nitrate is not very toxic and it is use by algae or plants for growth in the aquarium.

Answer:

The dendrites are important for receiving action potential or other stimulation in order for neurons to become activated. Dendrites are electrical signals that receive extensions of the cytoplasm. These signals come in two fundamental forms: inhibitory and excitatory.

Explanation:

just did it on Edge hope this helped :)have a great life bros

The function of dendrites is to receive signals and information from other cells. They have roots like structure.

Thin structures that emerge from the cell bodies of neurons are called dendrites. A neuron gets information from neighboring cells on its dendrite, or "tree branch." Like tree branches, dendrites branch as they advance toward their tips.

In order for neurons to become engaged, the dendrites are crucial for receiving action potentials or other types of stimulation. Electrical impulses are received via dendrites, which are cytoplasmic extensions. The two basic types of these signals are inhibitory and excitatory.

Therefore, dendrites have the ability to take in signals and data from other cells. They have structures-like roots.
