Explanation:

Multicellular organisms - composed of several different cells: Cells in these organisms differ in relation to the function to be performed.

The cells in these organisms are growing, developing, and reproducing.

The cells differ in shape, size, and role they have in the organism.

In the group of multicellular organisms are animals (Animalia), plants (Plantae), and fungi (Fungi).

Cells in many-celled organisms are often quite different from each other. Therefore option C is correct.

In many-celled organisms, such as animals and plants, cells can be specialized for specific functions, leading to their differentiation and diversification.

Different types of cells have distinct structures and perform specific tasks within the organism.

For example, nerve cells (neurons) are specialized for transmitting electrical signals, muscle cells for contraction, and blood cells for carrying oxygen and nutrients.

This specialization allows for efficient division of labor, where each cell type contributes to the overall functioning of the organism.

The diversity of cell types and their functions is a fundamental aspect of the complex organization and functioning of multicellular organisms, contributing to their overall biological complexity and adaptability.

Therefore option C are often quite different from each other is correct.

Answer:

c

Explanation:

there will be way less vegetation to attract pet and many organisms will die because of the lack of resources due to the drought

If the desert experiences a prolonged drought where many of the plants die, the carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.

Due to draught, resources decreases (resources becomes limited) and many organisms would die because of starvation. This would also effect in the food chain of other organisms. The organism would now compete for the lesser amount of resource.

Hence, the correct option is C. The carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.

During DNA replication, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.

It is the process by which DNA produces a copy of itself at the time of cell division. In the process of replication, the initial step is the unzipping of the double helix structure of the DNA. This is done with the help of enzyme helicase. The unzipping creates a Y shape composition called replication fork.

Towards the replication fork, one of the strands is oriented in the 3' to 5' direction, known as the leading strand. The other strand in the 5' to 3' direction is the lagging strand, which is away from the replication fork.

The primer combines with the leading strand, and marks the intiation point of the synthesis of DNA. After this, DNA polymerase combines with the leading strand and add complementary nucleotide bases in the 5' to 3' direction.

In the lagging strand, numerous primers come and bind, later the chunks of DNA called Okazaki fragments are supplemented to the lagging strand in the 5' to 3' direction, by the enzyme DNA polymerase. This kind of replication is termed discontinuous as the Okazaki fragments are joined up later.

Thus, the correct statement is the second one, that is,  the DNA polymerase enzyme produces a complemetary strand from each of the original strands.

Experimental Vaccine Herpes Vaccine = D

Attenuated = B

Purified macromolecule Vaccine = B

Recombinant-Vector Vaccine  = A

Inactivated or Killed = C

Diphtheria Vaccine = A

Explanation:

A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.

Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).

The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses

Answer:

0.079

Explanation:

Using Hardy Weinberg equilibrium for  blood group;

p² + 2pq + q² + 2pr + r² + 2qr = 1

where;

p = allele frequency for A

q =  allele frequency for B

r =  allele frequency for O

N(p² + 2pr) = the number of allele for type A people

N(q² + 2qr) = the number of allele for type B people

N(2pq) = the number of allele for AB people

N(r²) = the number of allele for O people

N(r²) = 316

r² = 316/1000

r² = 0.316

r = [tex]\sqrt{0.316[/tex]

r =  0.56

To find the frequency of the [tex]I^B[/tex] allele;

N(q² + 2qr) = 84

q² + 2qr = 84/1000

q² + 2qr = 0.084

where;

r = 0.56

q² + 2q(0.56) = 0.084

q² + 1.12q = 0.084

q² + 1.12q - 0.084 = 0

Using the quadratic formula:

[tex]=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]

where;

a = 1, b = 1.12, c = -0.084

[tex]=\dfrac{-(1.12) \pm \sqrt{(1.12)^2-4(1)(-0.084)}}{2\times 1}[/tex]

[tex]=\dfrac{-(1.12) \pm \sqrt{1.2544-(-0.336)}}{2}[/tex]

[tex]=\dfrac{-(1.12) \pm \sqrt{1.5904}}{2}[/tex]

[tex]=\dfrac{-(1.12) \pm 1.261}{2}[/tex]

[tex]=\dfrac{-(1.12) + 1.261}{2} \ \ OR \ \ \dfrac{-(1.12) - 1.261}{2}[/tex]

[tex]=\dfrac{0.141}{2} \ \ OR \ \ \dfrac{-2.381}{2}[/tex]

[tex]\simeq 0.079 \ \ OR \ \ -1.1905[/tex]

Since our value can be negative; then the frequency of the  [tex]I^B[/tex] allele in this population is 0.079.

Answer:

B. 0 m

Explanation:

From the position - time graph, the object would have traveled a distance of 0m after 6s.

The graph shows a decrease in distance traveled with increasing time.

If we trace up the time taken to the curve, the position will be 0m.

Therefore, the position of the body after 6s is at 0m.
