Answer:
Because it plays a major role in regulating body temperature.
Explanation:
The hypothalamus is the heating regulating center of our body which is placed in the hypothalamus. It plays a major role in regulating body temperature, acts as a thermostat and also helps to maintain homeostasis in lots of different ways, for example, by controlling our blood pressure.
When our body cools below the normal temperature it helps to switch up the heat-generating processes and when the body gets overheated it helps to switch off the heat-generating processes.
Answer:
A
Explanation:
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.
If nearly 79% of atmosphere is nitrogen, how could there be a shortage of nitrogen in some soils? Nitrogen must be converted into nitrates before organisms can use it. If soil lacks nitrogen fixing bacteria, then it has few nitrates for the plants to take in.
Answer:
All cells have a nucleus, which acts like the brain of the cell
Explanation:
prokaryotic cells don't have a nucleus
Answer:
C. The red and blue pigment alleles are codominant.
Explanation:
This pattern of inheritance described in the question is referred to as CODOMINANCE, which is a non-mendelian pattern of inheritance in which one allele of a gene is neither dominant nor recessive to the other allele, hence, both alleles are phenotypically expressed in the heterozygous state.
This is the case of the red and blue pigment alleles in this question. When two true-breeding parents (red and blue pigment) are crossed, they produce some offsprings that simultaneously expresses both of their phenotypes (red and blue stripes). This is because the alleles of those pigments are both dominant in the pigment gene, hence, they are said to be CODOMINANT
