Which of the following is considered a abiotic 

A : algae bloom
B : fish life
C : animals waste
D : sediment deposition

Answers

Answer:

sediment deposition

Explanation:

Abiotic factors are the non-living pieces of the climate that can regularly affect living creatures. Abiotic factors incorporate water, daylight, oxygen, soil and temperature.

Brainliest?

Answer:

D: sediment deposition

Explanation:

An abiotic factor in an environment is a factor that is not, nor has ever been alive, and it didn't come from a living organism. The opposite of abiotic is biotic; a biotic factor is alive. So, sediment deposition would be abiotic because, unlike the other options, it was never alive and did not come from a lining thing.

A doctor has diagnosed a patient with atherosclerosis. When listening to the blood flow through
might the disease diagnosis affect the sound being detected by the physician?
The blood flow sounds different because the blood is flowing through
vessels with a narrowing of the inner walls of coronary arteries due to
buildup of fatty materials.
The blood flow sounds different because there is a widening of inner walls
of blood vessels due to a high salt diet.
B)
The blood flow sounds different because the walls of the heart have been
stretched due to a heart attack
D
The blood flow sounds different because there is an increased circulation
to the heart.

Answers

Answer:

The blood flow sounds different because the blood is flowing through vessels with a narrowing of the inner walls of coronary arteries due to buildup of fatty materials.

Explanation: Atherosclerosis is characterized by cholesterol deposits in the walls of the arteries. This can be hereditary but is often impacted by increased fatty diets.

The disease diagnosis affect the sound being detected by the physician is when the blood flow sounds different. hence, the first option is correct.

Impact on the sound that being detected:

Since the patient was diagnosed with atherosclerosis so here the flow of the blood should be sounded different since the blood is flowing via the vessels that have the narrow inner walls because of fatty materials.

Also, Atherosclerosis should be contributed by the cholesterol that is deposited into arteries walls.

hence, the first option is correct.

Define the process of germination.​

Answers

Answer:

Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule.

or

Germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.

Germination is the process by which an organism grows from a seed or similar structure. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm

Researchers allow bees to feed from a feeder located 500 meters due south of the hive for several days in a row. They then place a new feeder due south of the hive and place feeders in several other directions from the hive as well, but all are now 450 meters from the hive. They leave the original feeder empty. Next, they determine which feeders that new bees from the hive now visit. What information can they learn from this experiment alone

Answers

Answer:

they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know.

Explanation:

From this experiment they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know. Since they have been accustomed to feeding from the feeder that is south they may continue to do so, but since it is not the farthest from the hive and there are other feeders located closer they may chose the new feeder. If they do decide to change feeder, then it tells the researchers that the Bees are able to calculate the distance and know that the new feeders are closer, while which feeder they choose might give them information on how bees determine direction.

A student remarks that it is a good thing that humans discovered how to use industrial processes to fix nitrogen because this ensures that the nitrogen cycle can remain intact if nitrogen-fixing bacteria ever go extinct. Evaluate the accuracy of this statement. A. The statement is accurate because humans are able to fix nitrogen on a large scale that rivals the rate of the process carried out by bacteria. B. The statement is inaccurate because the nitrogen cycle does not depend on nitrogen-fixing bacteria, and their loss would not cause a problem. C. The statement is inaccurate because the product of nitrogen fixation through industrial processes does not have the same biological properties as the product of nitrogen fixation by bacteria. D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.

Answers

Answer:

D. The statement is inaccurate because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now.

Explanation:

Nitrogen fixing bacteria has the responsibility in nature to trap and fix atmospheric nitrogen in ecosystems. They are very important components of the nitrogen cycle and play an important role in maintaining the balance  of nutrients in nature.

If humans discover industrial processes to fix nitrogen, the process will be unsustainable in the long run if nitrogen-fixing bacteria ever go extinct because humans would not be able to distribute the product of nitrogen fixation from industrial processes in the same way that bacteria are able to distribute it globally now across several ecosystems all over the world.

Which phylum to not have an internal or external skeleton or shell?

Answers

Answer:

exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton"[1]) is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells". Examples of animals with exoskeletons include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters, as well as the shells of certain sponges and the various groups of shelled molluscs, including those of snails, clams, tusk shells, chitons and nautilus. Some animals, such as the tortoise and turtle (shell page), have both an endoskeleton and an exoskeleton.
