Here is a Answer to your question:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
I am sorry if this was not helpful
Hope this was helpful
DNA also known as Deoxyribonucleic Acid is a double stranded macromolecule. The two strands of DNA are complementary to each other. For replication, the DNA double helix opens at one end, making the two strands free to which new strands begin to form and the process continues in a sequence for the whole length of the DNA.

Answers
Answer:
A. Adrenaline
Explanation:
adrenaline is a hormone

A female mosquito can produce 50-500 offspring in a two-week period of time. This rapid reproduction can also result in fast
evolution for this small insect species. For example, pesticide resistance occurs rapidly in insects, including mosquitos. Insecticides
that were once effective at eradicating mosquito populations are no longer effective. Which component of natural selection is
Likely playing a role in this rapid evolution for mosquitos?
A)
Mosquitoes pass only advantageous traits on to their offspring during
reproduction. This ensures increased survival and reproduction.
B)
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
Mosquitoes that learn to avoid pesticide exposure can pass that
information on to offspring. This increases the survival of those offspring
as well.
D)
Mosquitos have the ability to detect areas with high pesticide loads and
can avoid those areas. This allows mosquitos to survive and reproduce with
more success.

What are mosquitoes?Mosquitoes are ectoparasites, which live on the blood of different animals.
They suck blood from the skin of animals and leave red spots, which are itchy.
Mosquitoes lay their eggs in water and live in dirty, moist, dark places.
They are also responsible to cause malaria in humans.

HELP, define genetic engineering and Describe how DNA is modified for use in genetic engineering.
Answers
Answer:
Genetic engineering is deliberate modification of genome to gain desired traits.
The main steps of genetic engineering:
Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.

What is Crossing over and DNA replication
Crossing over involves the swapping of genetic materials, and it occurs in prophase I of meiosis before meiosis II the crossing over of genetic materials are over. while DNA replication is the process whereby DNA make an exact copy of itself during the process of cell division and this process occurs prior to meiosis I and meiosis II

Answers
As organisms became more active, a four-chambered heart was selected for because of its ability to separate oxygenated and deoxygenated blood.
Why is a four-chambered more efficient in oxygen delivery than a two-chambered heart?A four-chambered heart is a heart consisting of four chambers, namely;
upper ventricle lower ventricle upper atrium and lower atriumA four-chambered heart is more efficient in oxygen delivery than a two-chambered heart because it does not allow for mixing of oxygenated and deoxygenated blood.
