Centromeres split apart during what phase of mitosis

In your own words, explain the organization of the

Illusion [34]

Answer:

Zygote is formed by fusion of 23 chromosomes from female and 23 chromosomes from male

This fusion happens through a process of fertilization to form an egg

The human zygote consist for 46 chromosomes and is diploid in nature

During the process of fusion,the sperm combines with the membrane of the ovum

Later the zygote is formed and become activated for the cell division for the formation of embryo

Embryo is form by undergoing different stage of development namely :-

1)morula

2)blastula

3)gastrula

How do enzymes work?

motikmotik

Enzymes speed up all of the reactions that happen inside cells. They help with digestion and our metabolism. Enzymes can do a few different things like:

Break up big molecules into smaller pieces, so they can be absorbed more easily by the body.

Enzymes also are very picky catalysts, and will only “speed up” certain types of reactions.

Hope this helps you!! (:

Describe how climate would be influenced if:

madam [21]

The rate of energy coming from the Sun changes slightly day to day. .It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes.
The axial tilt angle affects climate largely by determining which parts of the earth get more sunlight during different stages of the year Likewise, during winter for the northern hemisphere, there would be fewer hours of daylight because the northern hemisphere would essentially be pointed away from the sun.
If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere, blocking the radiation from the Sun. This would cause the global temperature to decrease drastically.
The Sun's irradiance has its greatest effect on Earth's upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth's warming, one would expect to see that upper atmosphere getting increasingly hot.\
have a nice day sorry if wrong T_T

If sunlight is the source of energy for most organisms on earth, how are humans and other animals able to utilize this energy if

mixas84 [53]

Humans get D vitamin from sunlight. the plants perform photosynthesis and grow , we eat those fruits and vegetables grown in the plants. so indirectly we humans and other animals are benifitted from sun sunlight . flesh eating animals eat herbivores animala so they are also benifitted
