I Need Help With This Can Someone Help Me?

Answers

Answer 1

Explanation:

Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

Which level of organization is represented by the skeleton of the snake?

А.organ

B.organism

C.tissue system

D.organ system

Answers

The answer for this question is C

Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.

What level of organization are present in snake?

The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.

The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).

A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.

This enables the snake to move forward by pushing against the ground while bending and curling its body.

Therefore, tissue system  level of organization is represented by the skeleton of the snake.

ASAP IMAGE IS ATTACHED THIS IS NOT DIFFICULT


There are only 4 types of nucleotides in mRNA and 20 types of amino acids in proteins. This figure shows how 4 types of nucleotides can provide a unique code for each of the 20 types of amino acids.

6a. The mRNA code for each type of amino acid is a

sequence of _______ nucleotides, called a codon.
(2 / 3 / 4)

6b. In the figure, which mRNA codon codes for the amino acid Phe?

Answers

Answer:

The mRNA code for each type of amino acid is a  sequence of three nucleotides, called a codon.mRNA codon that codes for the amino acid Phe es UUU.

Explanation:

The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:

An amino acid can be encoded by more than one codon. From these combinations the three STOP codons are obtained.

A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.

Phenylalanine (Phe), according to the image, is formed with the UUU codon.
