When human skin suffers a cut, the process of healing rapidly begins allowing for wound closure and healing within a few days. Keloids occur when skin around wounds continues to grow after the skin has healed. A disruption in the regulation of which cellular process is probably responsible for this condition
Options
A. Mitosis
B. Meiosis
C. Apoptosis
D. Phagocytosis
Answer:
A
Explanation:
Mitosis is a type of cell division which takes place in living organism during growth and development.Therefore it is ensures the regenerations of cells and tissues during healing.
Therefore the restoration of new cells to the skin following injuries is due to mitosis.Since this is a multiplication division(2n) in which the daughter cells are exactly like the parents' cells the new tissues of the skin by mitosis, look exactly like the previous one that was injured.
In cases where the mitotic growth control is lost, the scare tissues of the injured part overgrows with granulation tissues and this leads to Kaloids.
Its is a mass of Collagen Type 1.(Collagen is an fibrous proteins which has largest proportion in mammals).
Keloids is characterized with pink or red coloration and elevation of the area,excessive growth of the area, with irritating patch skin

After school, Kai feels hungry and tired. He finds some sugar cookies in the cabinet and finishes the whole package.
Which statements best describe the role of glucagon and insulin in this scenario?
O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin
was secreted after he ate the cookies because his blood glucose was high.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. Glucagon
was secreted after he ate the cookies because his blood glucose was high.
O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he
ate, insulin from the cookies increased his blood sugar levels.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he ate,
glucagon from the cookies increased his blood sugar levels.
Answer: Option A) Glucagon was secreted by his pancreas before he ate the cookies because blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.
Explanation:When Kai was hungry and his blood glucose level was decreasing, glucagon is the hormone which was secreted by the islets of pancreas to increase the blood sugar levels in his body. Glucagon forces the liver to release the stored glucose in it, which increases the blood glucose level in the body. When Kai ate the sugar cookies there was enough of blood glucose available for his body, also it exceeded the requirement and went high. Insulin was then secreted to control this excess glucose from the islets of pancreas. As it helps the body cells to absorb the glucose and lowers the amount of glucose in the blood. It makes the cell available with the glucose to produce energy and perform their activities.
In short, glucagon and insulin both are secreted by the same organ which is islets of pancreas. But they differ in their function, glucagon increases the blood glucose when the body needs it, whereas insulin helps to absorb the excessive glucose and stores that in the body. Both are the hormones which help in regulating the body glucose levels.
During process of digestion which takes place in digestive tract statement which describes role of glucagon and insulin is glucagon was secreted by pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate cookies because his blood glucose was high.
What is digestive tract?It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

The evidmence can support the Hypothesis or invalidate the Hypothesis.
Explanation:
Drag each label to the correct location. Classify the interactions as being direct or indirect competition. Two eagles fight over a salmon carcass. All the gray foxes in a habitat prey primarily on penguins. Two colonies of black ants clash over a wasp. Gray squirrels in an area rely on nuts for food.
Answer:
Two eagles fight over a salmon carcass- DIRECT
All the gray foxes in a habitat prey primarily on penguins- INDIRECT
Two colonies of black ants clash over a wasp- DIRECT
Gray squirrels in an area rely on nuts for food- INDIRECT
Explanation:
Living organisms of same or different species tend to interact with one another in their natural habitat. One of those interactions is competition, which occurs when living organisms share the same limited resources or occupy the same niche in their habitat.
However, competitive interaction between organisms can either be direct or indirect. Direct interaction is that which involves a physical interaction between the organisms i.e. a confrontation. A struggling for the limited resource is evident. For example, two eagles fighting over a salmon carcass and two colonies of black ants clashing over a wasp shows the form of physical confrontation for the limited resource between the organisms involved. Hence, they are examples of direct competition.
On the other hand, indirect competition involves the competition for a limited resource without a physical confrontation or struggle. Organisms make use of the limited resource until it becomes unavailable to competitors. For example, gray foxes in a habitat that prey primarily on penguins and gray squirrels in an area relying on nuts for food shows a competition for a scarce resource without any physical interaction between them. Hence, they are examples of indirect competition.

What has a greater influence on protein levels?
(1 point)
Protein degradation has a greater influence because outside factors like antibiotics can
cause it, and it is difficult to recover from.
O
Protein degradation has a greater influence because they are denatured faster than the cell
can produce them.
mRNA destroyer concentration has a greater influence because it is destroying mRNA before
proteins can even be produced.
mRNA destroyer concentration has a greater influence because mRNA is destroyed right
after the proteins are produced.
Answer:
mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced.
Explanation:
Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.
Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.
What are intermediate species? in an easy way to understand. And some examples?
Answer:
An intermediate is a species which appears in the mechanism of a reaction, but not in the overall balanced equation. Examples: Amphibian/land vertebrate (Pederpes)- Intermediate form between primary aquatic Upper Devonian amphibians and early tetrapods. Lizard/snake (Pachyrhachis)—Intermediate form of snakes and an extinct lizard-like reptile. It was a primitive snake with limbs.
Explanation:
Answer: These are certain species that create “connecting links” or something like that, between the fossil record of life which help to show the slow process of speciatin.

How are the proteins inside your body affected by the presence of water and other molecules?
Answer:
Our body is constitute of several essential molecules such as proteins, fat, carbohydrate, water, and other molecules.
Each molecule has some of the impact of other molecules in the body. Impact of water and other molecules on proteins inside the body are as follows:
Proteins have ligand-binding site and water provide stability to the ligand-binding site of proteins through its hydrogen bonds.Conformational flexibility and transitions of proteins are due to the presence of water molecules in it.Disbalance in the pH of body due to changing concentration of sodium-potassium ions can denature the protein. Enzymes present in the body can control the rate of formation of proteins in the body.

Menstrual Phase
Follicular Phase
and Luteal phase
Thanks!!!
Answer:
(menstrual phase) this is the phase where the unfertilized ovum and endometrium that was formed in readiness for implantation slough off or come out due to a sudden drop in progesterone levels
(follicular phase) this is where the graafian follicle in the ovary develops. from primary follicles due to secretion of follicle stimulating hormone by the pituitary gland and matures there after due LH hormone which will also stimulate the ovary to release the ovum
(luteal phase)this is the phase after the ovum has been released where the remains of the ruptured graafian follicle undergo reorganization to form a corpus luteum/yellow body which now produces progesterone which causes thickening of endometrium in readiness for implantation
hope this helps
Answer:
The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. 2) The follicular phase is a phase of the estrous cycle during which follicles in the ovary nature from primary to a fully mature grafian follicle.It ends with ovulation.3) The luteal phase begins during the second half of a menstrual cycle normally lasting around 12 14 days after the ovulation and it is responsible for producing progesterone.

Evaluate this statement: Gene flow increases the genetic divergence of populations. Evaluate this statement: Gene flow increases the genetic divergence of populations. This statement is true. This statement is false. Gene flow is not able to influence the genetic divergence of populations. This statement is false. Gene flow reduces the divergence of populations. This statement is false. Gene flow increases the number of genes in populations.
The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.
Explanation:
In biology and related areas, genetic divergence occurs if populations with a common ancestor develop unique traits, which are the result of genetic changes over time. On the other hand, gene flow occurs when traits including genes flow from one population to another, usually because the populations are in contact. In this context, gene flow reduces divergence because if genetic material flows between populations is less likely each population can develop unique traits, instead the populations involved will have similar traits after some time.
The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.
The following information should be considered;
In terms of biology and related areas, genetic divergence arise at the time when the populations are with a common ancestor that created unique traits, due to this there are genetic changes over time. While gene flow arise at the time when traits involved genes flow from one population to another, normally due to the populations are in contact. In this given situaton, gene flow reduces divergence since genetic material flows between populations is less likely every population can create unique traits, rather the populations involved will have similar traits.Learn more: https://brainly.com/question/5303391?referrer=searchResults
