Answer:
The most appropriate explanation would be the presence of two types of melanin in hairs.
In human hairs, two types of melanin are present: eumelanin and pheomelanin.
Eumelanin determines the darkness of the hairs, that is, it would determine if the hairs of a person would be black or brown.
Pheomelanin is responsible for orange or red colors of the hairs. In addition, on breaking down, it provides the hairs with colors like red, orange, yellow and white (complete breakdown of pheomelanin).
DNA to 8. the genetic blueprint for all cells
Nucleus to 5. acts as the "brain" of a cell
Connective cells to 9. tendons, blood, and fat are examples of these cells.
Epithelial tissues to 6. designed to regulate temperature, secrete lubricants, and protect the body from harmful substances.
Cytoplasm to 7. fluid like substance in a cell
Organelles to 3. structures that perform special functions within a cell
These are the only ones I know.
I think the answer would be mid-noon.
Answer:
Winter and Summer season
Explanation:
The season occurs on earth because of the tilt of the earth's rotational axis. There occurs variation in season from one place to another depending upon various factors, in both the northern and the southern hemispheres.
In the higher latitudinal areas, in both the hemispheres, there occurs winter and summer season. During the time of winter in the northern hemisphere, the earth comes closer to the sun, but because of the tilt of the earth's rotation axis, it can reflect the majority of the incoming solar radiation back into space. The winters are usually characterized by the occurrence of low average temperature and the duration of daylight is much shorter.
On the other hand, during the time of summer, the earth is at the furthest from the sun, but most of the solar radiation easily enters the earth's atmosphere. It is due to which the average temperature increases and the duration of daylight are longer.
