What is mitosis?Mitosis has been defined as the process by which the cell divided it has been chromosome and then to separate them and the identical nuclei that has been produced for the preparation of the division of the cell. During the process of the mitosis as a single cell divided into the identical daughter cell.
There are four stage of the mitosis and these are mentioned below:
1- Prophase
The first stage of the mitosis in which the size of the chromosome has became the short and thicken in the shape.
2- Metaphase
This is known as the second stage of the mitosis in which the chromosome lies in the mid of the cell.
3- Anaphase
During this stage of the mitosis has been chromatides will break and they have to move to the opposite poles.
4- Telophase
Telophase has been known as the last stage of the mitosis in which two nuclei formed.
Therefore, Devise as way to remember each stage of mitosis and the correct way to learn is PMAT and the full form of the PMAT is P- prophase - chromosomes appear - P, M- metaphase - chromosomes in Middle - M, A- anaphase - chromatids moved Away - A, and T- telophase - Two new cells -T.

Which of these is evidence of global warming?
OA. Stable precipitation patterns
O B. Falling global temperatures
OC. An increase in the size of glaciers
OD. Overall rising sea levels
The evidence of global warming is best seen in the overall rising sea levels.
How high are the seas?The average height of the ocean's surface above the surface of the land is referred to as sea level. It is a crucial gauge of climate change on Earth and is influenced by a number of variables, such as variations in global temperatures, ocean currents, and land movements.
This is brought on by the melting of glaciers and polar ice caps as well as the thermal expansion of warming seas. Sea levels are increasing more quickly as the earth heats, which is a direct outcome of global warming.
The other possibilities, such consistent precipitation patterns, declining global temperatures, and an expansion of glaciers in size, are not necessarily signs of global warming.

In cellular respiration, the energy for most ATP synthesis is supplied by:
A. High energy phosphate bonds in organic molecules
B. A proton gradient across a membrane
C. Converting oxygen to atp
D. Transferring electrons from organic molecules to pyruvate
E. Generating carbon dioxide and oxygen in the electron transport chain
Answer:
B. A proton gradient across a membrane.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
In cellular respiration, the energy for most ATP synthesis is supplied by proton gradient across a membrane.
This ultimately implies that, most adenosine triphosphate (ATP) is formed due to the net movement of protons against a concentration gradient in the electron transport chain.

How do simple and complex sugars compare in their effect on your glycemic index?
Answer:
The glycemic index allows you to compare the ability of foods to increase blood sugar (glucose) levels. In general, simple carbohydrates have a medium to high glycemic index. In the case of complex carbohydrates, this varies.
Explanation:
The Glycemic Index (GI) is a measure that provides information on how quickly blood sugar levels rise after eating a certain food. Low glycemic index foods are those that have a low content of sugars or simple carbohydrates and that help regulate blood glucose levels, the consumption of foods with a low glycemic index has been proposed as a prevention and / or management factor of obesity, cardiovascular diseases, type 2 diabetes mellitus and some types of cancer. Complex carbohydrates are made up of larger, more complex molecules and are found primarily in the form of starch and fiber. Foods high in fat or fiber are digested more slowly, so they also cause a slower rise in blood sugar. A food with a high GI raises blood sugar faster than foods with a medium or low GI. The GI is higher when foods do not contain fiber and they are easily digested, since they reach the bloodstream quickly, it is also higher if there is sugar or if cooking destroys part of the fiber and favors the digestion of food.

A genetic engineer wants to isolate a gene from a scorpion that encodes the deadly toxin found in its stinger, with the ultimate purpose of transferring this gene to bacteria and producing the toxin for use as a commercial pesticide. Isolating the gene requires a DNA library. Should the genetic engineer create a genomic library or a cDNA library
Answer:
The correct answer is - Yes, the genetic engineer should create a genomic library or a cDNA library.
Explanation:
mRNA isolated from the toxin extracted from the venom gland of the scorpion to create a cDNA library. The cDNA sequence is reverse transcribed by the mRNA that lacks the introns as prokaryotic organisms such as bacteria cannot splice introns.
If the engineer wants to express the toxin in bacteria then he required a cDNA sequence as a genomic clone can not use to clone for making proteins. mRNA should be isolated from the venom gland so it can synthesize cDNA library enriched with toxin protein sequence.
