Compare and contrast what happens in mitosis and meiosis and discuss the importance of each process to a living organism.
Semenov [28]

In mitosis, the first stage is prophase. The nucleolus disappears and the two centrosomes begin to form the mitotic spindle. The spindle xtends between two opposite poles f the cell. Next is the metaphase. The centromeres of the chromatid pairs align at the center of the miotic spindle. Then anaphase, the centromeres will split that separates the chromatid pair. They are now called chromosomes. The last phase is the telophase. The chromosomes will then form a thread-like chromatin and for ache envelope, a nucleoli appears. <span>The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.</span>

A bird is flying in the air at a 4 m/s. If the mass of the bird is 7kg what is it’s kinetic energy
yaroslaw [1]

Answer: The kinetic energy of the flying bird is 56 Joules.

Explanation:

Mass of the bird  = 7 kg

Velocity of the flying bird = 4 m/s

Kinetic energy of the bird will be given by :

K.E.=\frac{1}{2}mv^2

K.E.=\frac{1}{2}\times 7 kg\times (4 m/s)^2=56 Joules

The kinetic energy of the flying bird is 56 Joules.

According to the competitive exclusion principle, two species cannot continue to occupy the same A) habitat. B) niche. C) territ
levacccp [35]

Answer:

Niche

Explanation:

Niche basically is the lifelihood of a species that involves feeding on what, drinking from what....

If both species are competing for the same resources, they would compete until a certain species is eradicated. (think of it as 2 species of ants in 2 colonies that are close to each other, take the same leaves, prey and stuff. They would fight with each other in other until one colony is eradicated.) hence, unless a species and adapt and change its niche, both species would fight until one is eliminated. Thus, the principle states that 2 species cannot continue to occupy the same niche, not living environment.
