Answer: The primary motor cortex for control of voluntary muscles is found in the precentral gyrus of the frontal lobes.
Explanations:
The primary motor cortex is one of the important brain areas involved in motor function. It is found in the precentral gyrus of frontal lobes. It control voluntary muscles and generate impulses needed for movement execution.
Voluntary muscles are muscles that we can control consciously or we can control them at will and we can choose when we want to use them. They are also refers to as skeletal muscles and are attached to bones. The are majorly use for locomotion.
Hi there!
Regulating species and plants in a certain area is beneficial for a lot of reasons. Below I'll list one of the most important reasons for regulating.
- Invasive species. As a direct result of the danger invasive species pose, regulating animals and plants in an area can help reduce the risk of a non-native species wrecking havoc on the environment. In the past and as of today many pet owners buy plants and animals from across the globe. Once they get too big some release them into the environment without any regards for the potential disaster it could bring. An example of this would be the Burmese Python which completely upset the ecosystem of souther Florida once let loose.
Answer: Please refer to:

Explanation:
Not sure but hope it helps.
Answer:
Objects able to block all the light are called opaque and will form a shadow. ... The closer an object is to the light source, the larger the shadow it casts. This is because an object closer to the source will block a larger area of the light, increasing its shadow size.
Explanation:
Yes. During meiosis Diploid (2n) mother cell produces fou haploid(n) daughter cell.
Explanation:
- Meiosis is also known as Reduction division.
- It is type of cell division by which a diploid mother cell produces haploid daughter cell.
- It is termed as reduction division because the number of chromosomes are reduced to half in daughter cell.
- Meiosis occurs only in sex cells to produce gametes.
- Significance of meiosis lie in the fact that it reduces the number of chromosome into half and thus helps to maintain the chromosomal number of the species in the zygote after fertilisation .
- Meiosis has two steps : Meiosis I and Meiosis II. There is a time gap between two steps, called interkinesis.
- Meiosis I involves replication , crossing over etc.
- Meiosis II is similar to mitosis however, no DNA replication occurs prior to meiosis II and the DNA content is thus halved in Daughter cell.
