pychu [463]
In the open ocean, especially around the surface, one of the main sources of food for fish would be the algae that grow at the surface & photosynthesize with the sun. Without fish to regulate the amount of surface algae, they overgrow and block the sun from the organisms on the coral reef.

Without sun, the reef is not able to sustain themselves & it's down hill from there.

I hope this helps!

Novay_Z [31]

Ans.

The first pass effect is defined as a phenomenon of metabolism of drug, in which drug concentration is greatly decreased before reaching the systemic circulation. It represents that fraction of drug lost, at the time of absorption of drug in gut.

Thus, the client is not receiving all the dosage of ingested drug (aspirin) because of the 'first pass effect.'

Since each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber.
timama [110]

Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens

Mechanism :

Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.

To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.

Supply the appropriate labels for all numbered parts of the illustration.
tatiyna

Answer:

This diagram depicts the phenomenon of DNA translation in the central dogma of life. Here are the labels

1. <u>RNA strand</u> because it is a sequence of four nucleotide A, G, C, U. It has Uracil, this is why it is RNA. Further, translation takes place when DNA is already transcribed.

2. <u>Ribosome</u> is a machinary for protein formation. This is because it provides right environment to transfer RNA to decode RNA strand into a protein sequence.

3. <u>Amino acid</u>: Each amino acid is carried by a transfer RNA (tRNA). The type of amino acid depends on type of tRNA. All proteins are mostly formed with 20 amino acids and so there are at least 20 tRNA.

4. <u>Polypeptide (protein) chain made up of amino acids</u>: It depicts multiple amino acids, which tRNA carries, and are bonded together through peptide bonds.

5. <u>Transfer RNA (tRNA)</u>: tRNA has a complementary sequence to RNA strand and thus it binds with right sequence. It carry an amino acid which is then bonded to another amino acid amino acid to make a polypeptide chain.
