Tundra
Explanation:
Tundra is a biome that has low Precipitation. Precipitation is a form of water that fall from the atmosphere to the Earth surface. Which could be inform of snow, sleet e.t.c.
Tundra is the coldest of all types of biomes. It has low temperature, little precipitation,low nutrients. It is located near the north Pole of the Earth. It is characterized by permafrost, permanent frozen layer on its surface.
The answer to this question is the "Retrograde Amnesia". When Justine was involved in an automobile accident and sustained a serious and critical injury to his sensitive part of the body which is the forehead. When he is being asked about the accident, Justin could not remember what happened on how the accident occurred. So Justin seems to be suffering from RETROGRADE AMNESIA.
Answer:
Mitosis is the division of somatic cells in which the genetic content or number of chromosomes remain intact in daughter cells.
So the correct option is ' Eighteen'.
Explanation:
Answer: 2 cells, Prophase 1, chromosomes lining up at equator of cell, anaphase 1, four times
Explanation:
Answer:
The correct answer would be 10.
The cell cycle can be divided into four phases namely gap 1 (G₁) phase , synthesis (S) phase, gap 2 (G₂) phase, and mitosis (M) phase.
DNA (deoxyribonuceic acid) content is only replicated and doubled in the S phase. However, the chromosome number remains the same. It can be explained as the number of chromosomes remains the same (2n) but number of chromatids doubles (4n) after S phase.
The number of chromatids restores to 2n in daughter cells after completion of mitosis.
Hence, if number of chromatids in metaphase was 20 i.e. 4n then the number of chromosomes (2n) would be 10.
Hence, 10 chromosomes or 5 pairs of chromosome would be present in the cell during its G₁ phase.
