Answer:
Mitosis only
Explanation:
Mitosis and meiosis are both types of cell division. Mitosis allows cells to proliferate for growth and repair. So this is how skin cells form new cells.
Meiosis is a type of cell division specific to reproduction. It forms the gametes, which are the egg and sperm. It generates haploid cells that fuse via fertilization to create a zygote.
Answer:
Photosynthesis is defined as the process by which plants make their own food in the presence of sunlight by utilizing water and carbon dioxide and produces energy.
The whole of process of photosynthesis can be represented by the following chemical formula:
6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2
CO2 - carbon dioxide
H2O - Water
C6H12O6 - Glucose
O2 - Oxygen
During photosynthesis glucose is formed from water and carbon dioxide and produces energy which is further converted into pyruvate that releases adenosine triphosphate (ATP) through cellular respiration. Oxygen is also formed.
The process takes place in two sequential stages Light dependent reactions and light-independent reactions.
<span>The sunspots are eruptions of heat and light energy emitting from the surface of the sun. These can increase our energy absorption many times above normal. Especially if it is pointed directly at the earth. These have been known to disrupt several bands in the radio spectrum and have knocked out communications of satellites. Naturally all this energy would have a great effect on our earth in many ways, climate included.</span>
Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.
