During genetic engineering, what is the function of a Ligase enzyme? A. To create a plasmid. B. To bond the target gene to the plasmid with covalent bonds . C. To create sticky ends to bond to gene to the plasmid. D. To cut the DNA at a Recognition site.
Answer:
C
Explanation:
In DNA cloning, restriction enzymes and DNA ligase are used to insert genes and other pieces of DNA into plasmids.
Genetic engineering is the field that uses technology and deals with genetic material. It uses the ligase enzyme that joins the sticky ends of genes to the plasmid. Thus, option B is correct.
What is ligase enzyme?Ligase is a protein enzyme that is involved in catalyzing the large fragments of the genetic material with the plasmids to make recombinant DNA. It establishes new chemical bonds.
In genetic engineering, the ligase enzyme links the gene of interest to the plasmid's restriction ends (sticky end). They allow the integrity of the genome by joining the phosphodiester backbone of the genetic material.
It joins the gene with the restriction ends of the plasmid by the concomitant hydrolysis (covalent bonds) process of chemicals from large molecules. It allows the formation of the complete genome that now can replicate.
Therefore, option B. ligase bonds the gene with plasmids.

Is water biodegradable or non - biodegradable?
Answer:
Biodegradable
Explanation:
Q. 35 One treatment for high blood pressure is taking diuretics that prevent the kidney collecting ducts from reabsorbing water. How would diuretics reduce blood pressure? By increasing blood volume By decreasing blood volume By increasing heart rate By decreasing heart rate
The diuretics will increase the volume of urine. That means more water is taken from the blood and excreted. According to Boyle's law, the volume is proportional to the pressure(p1v1=p2v2). It means that if we decrease the volume of blood we also decrease the pressure.
That means second option

To celebrate her recent weight loss, Lisa’s friends decide to take her out for a healthy dinner. Lisa doesn’t drink alcohol because she knows the empty calories will contribute to weight gain. One girlfriend at the dinner has four margaritas and an extra shot of tequila before the food arrives. Is this friend’s behavior considered binge drinking?
Answer:
Yes
Explanation:
In the scenario being described in the question it can be said that Yes, the friend's behavior would be considered binge drinking. This is due to the fact that consuming four drinks or more for women is considered binge drinking, and she had 5. Binge Drinking is defined as when a pattern of drinking that brings a person's blood alcohol concentration (BAC) to 0.08 g/dl or above, which for men is 5 or more drinks, and for women it is 4 or more drinks in less than 2 hours.
The function of Mitosis is to produce daughter cells that _______. have the same number of chromosomes as the parent cell but not the same genetic make-up are genetically identical to the parent cell have a random assortment of maternal and paternal chromosomes
Answer:
The function of Mitosis is to produce daughter cells that are genetically identical to the parent cells. have the same number of chromosomes as the parent cell but not the same genetic make-up are genetically identical to the parent cell have a random assortment of maternal and paternal chromosomes
(The answer is underlined above)
Explanation:
Mitosis is a nuclear division. This division results in the generation of two daughter cells that are genetically identical to the parent cells and each daughter cell contains the same number of chromosomes and all cell content inherited from the parent cell. Mitosis is involved in cell development of new cells and old one, growth of both new cells and old ones, and asexual reproduction.
The chromosomes which are the DNA molecule that makes up the fundamental genome of the cell are copied before mitosis. This made sense to explain how important it is for chromosomes of the cell to be copied first before mitosis so as to enable the separation of the chromosome copies to give each cell a full set of identity similar to the one copied from.
The function of mitosis is to produce daughter cells, which are genetically identical to the parent cell.
What is mitosis?It is the process in which two daughter cells are produced, which are identical genetically to each other, and to the parent cell. The process initiates with a diploid cell with 2N chromosomes and 2X DNA content, and at the end of the process two identical cells get produced each having same number of chromosomes and DNA content.
The replication of all the eukaryotic cells takes place by the process of mitosis, apart from germline cells, which replicate via the process of meiosis. The different phases of mitosis are:
ProphaseMetaphaseAnaphaseTelophaseCytokinesisThus, the correct statement is that the daughter cells are genetically identical to the parent cell.

O Wave A has a higher frequency because it has a
shorter wavelength.
The waves have the same frequency because they
have the same wavelength.
O The waves have the same frequency because they
have the same amplitude.
Answer:
O. Wave A has a higher frequency because it has a shorter wavelength.
Explanation:
Wavelength refers to the distance between two crests while frequency refers to the number of waves passes through a specific point per second. Frequency and wavelength are inversely proportional to each other. Inversely proportional means if one increases, the other decreases and vice versa. If the frequency of the wave is higher so its wavelength becomes shorter and if the frequency of the wave is shorter so its wavelength is higher.
Answer: B.
Explanation: Wave A has a lower frequency because it has a longer wavelength.

If DNA replicated conservatively instead of semi conservatively, what would the banding pattern look like in a tube containing heavy nitrogen DNA (15N) grown in regular, or light, nitrogen (14N) for 1 generation? A. There would be one band of heavy DNA and one band of light DNA. B. There would be one band of intermediate DNA, and one band of light DNA. C. There would be one band of heavy DNA and one band on intermediate DNA. D. There would be one band of intermediate weight DNA.
Answer:
A. There would be one band of heavy DNA and one band of light DNA.
Explanation:
First, we must exclude that a 15N DNA is related to a heavy nitrogen, while a 14N DNA is related to a light nitrogen.
After that, it is important to understand what conservative DNA replication would be. This type of replication implies that the strands of the parental DNA would not be separated to form the daughter strands. Thus, the replication occurs with the DNA strands together, the daughter strands of newly formed DNA are also formed together, in this case. Thus, the parental 15N DNA would form another 15N DNA molecule, the same goes for the 14N molecule. With that we can say that the answer to your question would be "there would be a heavy DNA band and a light DNA band."

Predict what would happen if we had no system of lymphatic vessels, and tissue fluid was moved directly back into the circulatory system throughout the body.
Answer:
If there was no system of lymphatic vessels, there would be no drainage of excess fluid from the tissues and the lymphatic fluid would accumulate in the tissues, causing them to swell.
Explanation:
The lymphatic vessel is made up of tiny vessels that are closed at one end and can be found in the spaces in the cells, except the central nervous system and the non-vascular tissues.
The main function of the lymphatic vessel is to move lymph which is a fluid that contains infection-fighting white blood cells to every part of the body.
So, if there was no system of lymphatic vessels, and tissue fluid was moved directly back into the circulatory system throughout the body. the lymphatic fluid would accumulate in the tissues, causing them to swell.

Describe how the water cycle moves water between the tree, the lake, and the sky in the picture below. Describe at least three of the water cycle processes you have learned about in the course. (10 points)
Answer:
The heat from the sun warms the water in the lake which evaporates and turns into water vapours. The water in the tree also rises into the atmosphere through a process, transpiration.
The water vapours rise into the atmosphere and forms clouds.
The water vapours in the clouds than condense into liquid water. Soon they'll get heavy and the water will fall down as rain, sleet, or snow.
Some of the rainwater sinks into the ground and is taken in by the roots of trees and plants.
This process keeps going on and on, and the water keeps shifting between the lake, tree and the sky.

Proteins play key roles in olfaction. One kind of protein, called ___________, attaches itself to hydrophobic odorant molecules so that they may dissolve in watery mucous. A second class of proteins, to which odorant molecules become bound and initiate transduction, are coded by the largest family of genes in mammals and are called ___________ . Group of answer choices
Answer:
The correct answer is "Odorant-binding proteins (OBPs); Olfactory receptors (ORs)".
Explanation:
Odorant-binding proteins (OBPs) are low-molecular soluble molecules that are secreted in high amounts in the nasal mucus layer. The precise biological activity of OBPs remains unclear, however, its solubility and ability to attach to hydrophobic odorant molecules suggest that they acts as carriers. A second class of proteins called olfactory receptors (ORs), act at the genetic level by initiating transduction once odorant molecules attach to them. ORs are coded by the largest family of genes, which include more than 100 genes and pseudogenes that represent around 3% of the genome.
