28 find that the cell spends in prophase (number of cells in prophase divided by the total # of cells (36) multiplied by 100)
Answer:
Difference is living and nonliving nature whereas similarity is both depends on environment.
Explanation:
Differences between type of vegetation and form in degraded and non degraded area is that vegetation is living whereas the degraded area is nonliving while on the other hand, similarities between vegetation type and form in degraded and non degraded area is that both depends on the environmental conditions such as temperature, moisture etc. Vegetation needs solar radiation and water to grow and to make their on food whereas the factors of environment causes degradation of the area if the environmental conditions are harsh.
Answer:
X inactivation
Explanation:
The female mammals have double the number of X-linked genes as compared to their counterpart males. During early embryonic development, either the maternal or paternal X chromosome in all the cells of a female is inactivated by the process of heterochromatinization. The inactivated X chromosome is present in the form of a Barr body. This inactivation of the X chromosome is a random event.
The inactivated X chromosome of a cell remains in the same state in all of its progeny cells. In this way, the process of X inactivation balances the dosages of X-linked genes between males and females.
Facilitated transport refers to a type of transport which does not require energy to occur. An example of facilitated transport is faclitated diffusion in which molecules just diffuse from one point to another across a membrane. For instance, glucose use facilitated transport to move in and out of cells.
Active transport refers to a type of transport in which energy is needed for it to occur. Example is the uptake of glucose in the small intestines of humans.
Answer:
The cerebellum (back of the brain) and the brainstem (middle of the brain)
Explanation:
Muscle movement coordination can be<em> voluntary</em> or <em>involuntary</em>. There are different sections of the brain responsible for the two;
- Voluntary movement of muscles is coordinated by the brainstem in addition to other functions such as sneezing, swallowing, vomitting, etc.
- Involuntary coordination of muscles is controlled by the cerebellum in addition to maintaining posture, balance and body equilibrium.
Hence, both the cerebellum and the brainstem are responsible for coordinating muscle movement.
