Answer:
Food is rearranged through chemical reactions, forming new molecules that release energy as this matter moves through an organism. Molecules are broken apart and put back together to form new substances, and in this process, energy is released.

Answer:
all of their children would have a widow's peak hairline
Explanation:
Chris's genotype consists of two dominant widow's peak genes and Janet has two recessive widow's peak genes so the each of the children will inherit one dominant and one recessive widow's peak genes from each parent, making them exhibit "v" shaped hairline and also being carriers for straight hairline.
DNA replication occurs in the 5 prime (5') to 3 prime (3') direction.
I'm sure you've heard this many times. I tutor in genetics, and all of my students can rattle that off. Less understand what it means.
First, understanding what 5' and 3' mean is important. DNA is composed of a ribose sugar, a phosphate group, and a base (A,T,G,C). The sugar has a phosphate group attached to its fifth carbon, and a hydroxyl group on its 3rd carbon. Nucleotides (separate components of DNA) are linked by the phosphate group and the hydroxyl group. So, every nucleotide is linked at the phosphate group and the hydroxyl group besides two - the two nucleotides at either end of the strand of DNA. The one that leaves a phosphate group exposed is called the 5' end of DNA, and the one that leaves a hydroxyl group exposed is called the 3' end of DNA.
<span>A problem with many students just memorizing that replication occurs in the 5' to 3' direction is that there are two strands of DNA involved in replication. DNA polymerase (the major enzyme responsible for replication) reads the already existing strand of DNA in the 3' to 5' direction, and creates the new strand of DNA in the 5' to 3' direction (meaning that it adds nucleotides to the 3' end of the new strand).</span>
Answer:
The correct answer is option- It brings in only a specifically targeted substance.
Explanation:
Endocytosis is the process by which cell engulfs or internalized the metabolites or molecules in the cell. Endocytosis is of three types phagocytosis, pinocytosis, and receptor-mediated endocytosis.
Receptor-mediated endocytosis is the process in which specific metabolite or hormone molecules are internalized in the cell. where is the phagocytosis all macromolecule or faulty cell or dead cells
Thus, the correct answer is option - It brings in only a specifically targeted substance.
