The atmosphere remains trapped with hot air
<span>The component of human milk that caries out the phagocytosis of bacteria is macrophages. Macrophages are also responsible for the production of complement proteins within human milk. Furthermore between 40% and 80% of breast milk is made up of macrophages, making it the most abundant cell type within human milk.</span>
Answer:
2.256
Explanation:
This is a percent change problem. The CO2 emitted by a car using gas is 4.7 MMt per year. The CO2 emitted by a car using corn ethanol made from biomass is 52% less than 4.7 MMt.
Find 52% of 4.7 MMt:
0.52 × 4.7 = 2.444.
Subtract 2.444 MMt from 4.7 MMt:
4.7 − 2.444 = 2.256.
The solution is 2.256 MMt.
Answer:
Because there is a mutation in region one that causes high level expression even in the absence of ethanol, region 1 must bind a transcriptional repressor and regulation of gene X must occur by relief of repression. Since a mutation in gene 2 results in a uninducibility of the gene, region 2 must bind a transcriptional activator. in the absenece of an activator the reprssor becomes irrelevant and the gene is in active regadless of conditions. Mutations in both regions 1 and 2 have the same effect as a single mutation in region 2, because in the absence of a bound transcriptional activator the repressor is irrelaevnat and the gene is inactive regardless of the presence or absence of ethanol
