Answer:
Hello! Sorry i am late! Here is my best answer below.
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

Why was the evolution of cyanobacteria such a significant event in Earth's history?
Answer:
Cyanobacteria are blue-green algae that produce chlorophyll and undergo photosynthesis. Oxygen, a byproduct of that photosynthesis, was released into the atmosphere, changing it in such a way that it may have allowed the evolution of more complex forms of life.

What kind of inheritance do you think the trait for the pedigree shows
Answer:
The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked. To start reading a pedigree: Determine whether the trait is dominant or recessive. If the trait is dominant, one of the parents must have the trait.

Which of the following is NOT a correct base pair?
A-C
T-A
C-G
A-T
Answer:
A-C
Explanation:
Hello There!
Remember these are the complementary base pairs
Adenine and Thymine (so the 2nd and 4th one are correct base pairs)
Cytosine and Guanine ( so the 3rd one is a correct base pair)
Hence, A-C would be the incorrect base pair because like stated previously Adenine pairs with thymine not cytosine

What is the last phase of the Cell Cycle? (This is when the genetic material has already been duplicated and what is left to do is to physically split up the rest of the cell - organelles, cytoplasm, etc. - into two separate, identical cells.)
Answer: mitotic phase
Explanation:
The cell cycle has two phases the Interphase and mitosis. Interphase is the growth phase where the cell prepares itself for the cell division. It is divided into three phase G1 phase( Cell growth),S phase ( DNA synthesis) and G2 phase(cell growth).
Mitotic phase has a multiple steps this is where the duplicated chromosomes are aligned or arranged, separated, and move into two new, identical daughter cells(cytokinesis)
The first step in the mitotic phase is called karyokinesis or nuclear division where the chromosomes are separated and move in opposite direction and the second portion of the mitotic phase, called cytokinesis which is the physical separation of the chromatids into the two daughter cells.

Explanation:
if a vector not have origin of replication result in what
Answer:
What will be the consequence of not having an origin of replication (ori) in the vector? Explanation: In the case ori is absent, the vector won't be able to replicate
Explanation:
As the replication won't take place, only one of the daughter cells would be having the vector. A colony of transformed colonies won't be obtained.
if a vector does not has the origin of replication result in not doing replication as the unit of replication is Ori.
In the case Ori is absent, the vector may not be capable of replicating. As the replication may not take place, the handiest one of the daughter cells might be having the vector. A colony of converted colonies may not be obtained.
What is transgene?
Of these, the maximum usually used vectors are plasmids. Common to all engineered vectors have a foundation of replication, a multi cloning site, and a selectable marker. The vector itself is normally a DNA series that includes an insert (transgene) and a bigger series that serves as the "backbone" of the vector.
Thus it is clear that if a vector does not have an origin of replication result in nonreplicating.

Explain and illustrate using chemical pathways how excessive alcohol intake can lead to; 1.Hypoglycemia
Answer: Alcohol can influence the blood sugar levels causing hypoglycemia.
Explanation:
Hypoglycemia is a condition in which the body experiences low blood sugar levels. Alcohol abuse can be one of the reasons for hypoglycemia. The occasional drinkers are affected negatively by this. It increases the secretion of insulin hormone which is a hormone necessary for keeping a balance of blood sugar levels in the body. The excess secretion of insulin can lead to decrease in blood sugar concentration and resulting in hypoglycemia. This can lead to type 1 diabetes.
Which of the following BEST describes the primary goal for meiosis:
Answer:
D) Daughter cells are produced with only half the chromosomes of the parent cell.

When humans perspire, water, urea, and salts containing sodium are removed from the blood. Drinking water during extended periods of physical exercise replenishes the water but not the sodium. This increase in water dilutes the blood and may result in the concentration of sodium dropping low enough to cause a condition known as hyponatremia. Symptoms of hyponatremia include headache, nausea, and lack of coordination. Left untreated, it can lead to coma and even death. The body has a variety of feedback mechanisms that assist in regulating water and sodium concentrations in the blood. The kidneys play a major role in these mechanisms, as they filter the blood and produce urine. The best way to reduce the symptoms of hyponatremia would be to
Answer:
The best way to reduce the symptoms of hyponatremia is to replace the body's sodium.
Explanation:
As seen in the question above, sweating causes the body to lose water and salts, such as sodium. We know that the excess of sodium in the body is harmful, however, the lack of sodium is also harmful, and can cause hyponatremia.
The loss of water in sweating can be reversed with water intake, but the loss of sodium must be reversed with sodium intake and the best way to do this is by eating salty foods. Sodium is one of the components of the salt used in the preparation of foods. In that case, when an individual eats salty foods, after having lost sodium molecules in perspiration, he will be replacing the lost sodium.

Which statement is accurate about natural selection?(1 point) A. Natural selection cannot inactivate genes. B. Natural selection does not impact reproduction rates. C. Natural selection does not change the alleles an organism has. D. Natural selection cannot occur through mutations.
Answer:
B
Explanation:
The correct option is "B" Natural selection does not impact reproduction rates according to the theory of Natural selection.
What are the factors of natural selection?Natural selection is the process through which populations of living organisms adapt and change. There are four factors are required for natural selection are reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.
Hence, the option is "B" Natural selection does not impact reproduction rates according to the theory of Natural selection.
