Explain how the water cycle removes pollutants from earth’s water

Biology
1 answer:
vaieri [72.5K]3 years ago
5 0

Answer:

During the water cycle, the water on the earth's surface gets evaporated leaving the impurities behind and enters into the atmosphere as water vapor. Thus, the water cycle removes pollutants from earth’s water.

Explanation:

Water cycle is the continuous movement of water on the earth's surface and the atmosphere. Some of the water from the oceans, lakes, rivers etc gets evaporated by sunlight and enters into the atmosphere as water vapor. Also from the processes like sublimation (ice and snow) and evapotranspiration (plants), water vapor reaches the atmosphere. This vapor is then condensed into clouds and later falls back from the sky on to the earth's surface as precipitations like rain, snow etc. During the evaporation, the pollutants (impurities) in the water sources are left behind. Thus, the water cycle removes pollutants from earth’s water.

A research team needs an antibody that binds to a protein of interest so that protein expression can be monitored. They use epit
antiseptic1488 [7]

Answer:

C.The added epitope disrupts the function of the tagged protein

Explanation:

When an additional sequence is tagged to a protein to use comercial antibodies, there are several reasons why this procedure wouldn't work as expected (note that we're assuming the protein is being expressed but it's not possible to detect it).

For example, the sequence of nucleotide added to codify for the tagged epitope are removed during the RNA processing. In that case, the protein would be expressed without the epitope, so it would be impossible to localize it with the antibodies.

Also, it could be that the new epitope is affecting some way the protein folding, making it not functional. This way, it would be degraded by the cell so it wouldn't be detected.

Another possibility is that the epitope doesn't affects the protein folding nor its function, but during the folding ends up in a conformation that makes it inaccesible for the antibody.

In summary, the way as the possible answers to this question are shown, the correct option seems to be C:<em> The added epitope disrupts the function of the target protein.</em>

1. Excretion is the process of (1 point)
ycow [4]
Q1. The answer is removing metabolic wastes from the body.
Excretion is the process through which metabolic wastes are removed from the body. Skin, lungs, and greatly kidney, which are the part of the excretory system, are responsible for excretion of metabolic waste in vertebrates. Invertebrates have special systems (insects, for example, have Malpighian tubules) or use skin to excrete metabolic wastes while single-celled organisms use the whole surface of the cell.

Q2. The answer is some animals live in dry or salty environments.
Kidneys are important organs in maintaining water balance. Some animals that live in dry and salty environments must preserve water in order to maintain homeostasis. They drink and eat food with more salt in it. If they lose that precious water in such conditions, the amount of different salts in the organism will increase and it will affect a normal functioning of the organism.

Q3. The answer is simple diffusion across the skin. 
Ammonia is very toxic substance and a lot of water is needed for its neutralisation and excretion. Therefore, animals that live in water excrete ammonia directly in the water. Many freshwater invertebrates eliminate ammonia through skin. In animals that do not live in the water, kidneys and liver help conversion of ammonia into urea which is then excreted.,

Q4. They both actively pump salt across their gills. 
Both saltwater and freshwater fishes use gills to eliminate nitrogenous wastes while kidneys have a little role in the elimination of this kind of the waste. Salt that is lost is replaced by active transport of salt ions into the body by the gills.

Q5. The answer is They both convert nitrogenous wastes to uric acid. 
A garden spider and a sparrow are terrestrial organisms. They do not live in the water and do not excrete metabolic wastes in the water. It is known that ammonia is toxic nitrogenous substance and a lot of water is needed for its excretion. For water organisms this is not a problem, they are surrounded by water, but terrestrial organisms, such as the garden spider and the sparrow, have no such amount of water in the environment, so their kidneys and liver must convert ammonia into urine which can then easily be excreted.

An adult female client describes the pain in her hand as having an audible grinding and cracking sound, especially in her thumb
slamgirl [31]

Answer: The correct answer to the question is option C

OSTEOARTHRITIS.

The client has a degenerative form of disease that is evidenced by osteoarthritis.

Explanation: Osteoporosis is otherwise known as degenerative joint disease.

In a healthy joint,a protective cartilage cushions the end of bones(articulating bones) and as well acting as a shock absorber.

In osteoarthritis,these cartilage that acts as a cushion to the bones wears down down or generates with time exposing the joint and the bones predisposing them to mild to moderate friction that occurs as a result of mobility of the bones/joint.

Osteoarthritis mostly affect joints of the hips, hands,spine and knees.

Some of the common symptoms of Osteoarthritis are;pain in the joints of the hands,knees,hips,lower back and neck with crackles,stiffness and tenderness of the joints which often results to difficulty in walking and deformity of the joint if left untreated.
