Answer:

Endangered species can be described as the species of animals or plants which are at the verge of extinction. Scientists tend to recognize the importance of every species in an ecosystem and make the world aware of the species which might go extinct. Nowadays, governments and citizens of a country pay much more attention to protect the endangered species.

Although, the wolves were a threat to some ecosystems but scientific researches have shown that these organisms can be beneficial in a number of ways. Hence, measures should be taken to protect these species. However, we can introduce species of wolves where the number of preys is more so that the ecosystem can be balanced.

DENIUS [597]

If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.

With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.

With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.

With a <span>heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.</span>

Compare and contrast the reasons cell division is important for unicellular and multicellular organisms. 2. Provide an example o

Ganezh [65]

(1)

For unicellular organisms, cell division is important for the reproduction of the population, Unicellular organism mainly use cell division, also called binary fission, for pollution growth. This is because unicellular organisms are only composed of one cell.

Multicellular organisms use cell division for growth and reproduction. Cell division causes increase in the number of cells composing the organism hence its growth in size. Cell division is also used to create gametes that are used in reproduction by fertilization.

(2)

Even in fully developed organisms, cell division is important in tissue repair. In tissue homeostasis, there is a balanced rate of cell division and cell death . An example in muscles. Due to the stress experienced by muscle cells, they usually have a lower life span and therefore the damaged cells are often replaced with new ones by cell division. This prevents tissue wastage.

(3)

Growth factors signal the growth of a cell. They usually bind receptors on the cell surface and indicate how the cell should grow and divide base don environmental stimuli. An example is during regular exercises. Growth factors indicate that the muscle cells should divide regularly and grow bigger to accommodate the higher stress in the muscles from the workout. This is how your muscles grow bigger and stronger with more exercise.

(4)

Differentiation of cells occurs through the silencing of some gene allowing the cell to produce particular proteins (and other biomolecules) that align with its functions in the body. This especially critical in multicellular organisms. An example is that while al the cells in your body have the same DNA, some cells differentiate into liver cells while others into lungs, stomach, heart, and etcetera.
