Answer:
C. The process occurs in the mitochondria of Eukaryotes.
Explanation:
In eukaryotes: glycolysis takes place within cytosol, Krebs cycle within mitochondrial matrix & ETC within inner mitochondrial membrane. Prokaryotes undergo binary fission(only cytokinesis) & conjugation.Prokaryotes undergo binary fission(only cytokinesis) & conjugation. Eukaryotes perform mitosis, meiosis(both karyokinesis and cytokinesis).Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.
Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

meiosis and cell differentiation.
Question 5
Why do some organisms reproduce aseggsually?
Question 5 options:
To rapidly produce like offspring
To increase genetic diversity
To have a variety of offspring at the same time
To get rid of genetic problems while reproducing
A) Crossing over occurs in : Meiosis I ( D )
B) DNA replication would occur : Prior to meiosis I and meiosis II ( B )
C) The embryo's development represents ; meiosis and cell differentiation ( D )
D) Some organisms reproduce aseggsually ; To rapidly produce like offspring
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
The development of an embryo in the missing diagram represents meiosis and cell differentiation.

HELP, define genetic engineering and Describe how DNA is modified for use in genetic engineering.
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.

Explanation:
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.
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
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.
