In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
Answer:
A
Explanation:
mtDNA is inherited from the mother of a child, this is because mitochondria are in the cytoplasm and the father's gamete (sperm cell) contributes very little or no cytoplasm to the zygote. We know that mitochondrial Eve came from Africa because the mutations in the mtDNA occurred before the <em>out-of-Africa dispersal</em>.
Answer:
This is the specific heat capacity
Explanation:
The specific heat capacity of water is the quantity of heat energy needed to raise the temperature of 1 g of water by 1 degree.it is due to the aggregation of hydrogen bonding holding water molecules together.
Therefore,large quantity of heat energy is needed to be supplied to raise the temperature of water.
This is an advantage for earth temperature because a significant rise in the earth temperature,would not affect the earth because the ocean would have absorbed the heat.Therefore regulating the earth temperature within the narrow limits
However,during summer little heat is released by the ocean and this cools the earth,this is because the specific heat capacity of the ocean is higher than that of the land,thus as the ocean warms up slowly its warms the earth.
If the pH/temperature fluctuates, the enzyme conditions would no longer be favorable, meaning the enzyme would no longer be able to perform its assigned function. If the conditions become too unfavorable, the enzyme would change shape (denature).
Answer:
Living Cells created from the dead grass
Explanation:
Because the water has nutrients.
