Answer:
Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
Explanation:
your welcome
Answer:
The correct answer is - 20000, 25,000 genes.
Explanation:
Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.
According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.
Thus, the correct answer is - 20000, 25,000 genes.
Answer:
A.it pumps hydrogen ions inside the cell
Explanation:
Principally, the main role of electron transport chain is to maintain the electrochemical gradient of hydrogen ions (H+) inside the mitochondrial matrix. This is the last step in aerobic cellular respiration and performs a series of redox reactions. Overall, it allows accumulation of H+ inside the mitchondrial matrix. This increased gradient or accumulation of hydrogen ions (H+) is essential because H+ would accept the electrons producing during the reactions. Without this, the flow of electron will be stopped because of high gradient, and production of ATP will not happen as well.
Indeed ETC helps in production of ATP but that is not the main function of electron transport chain rather it is a function of mitochondria.
The first step I believe is B. Enzymes break down the protective layer of the egg cell.
Answer:
The genes that are newly expressed after the stem cell has received the Self Renewal signal are: ID genes, DET genes and DIV genes.
Explanation:
Stem cells have the capacity of turning into different types of cells according to the needs of the tissue they're in. When these genes are expressed, the stem cell loses this potential.
