Answer:
It would change the nucleotide sequence of the transcribed mRNA
Explanation:
During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.
In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
Answer:
A change of the sequence of nucleotides in a DNA segment is called a mutation. This could change whether certain proteins are made that support the body or not.

A major factor in changing the frequencies of the genes in the gene pool
of a population is
A) domestication
B) migration
C) asexual reproduction
D) random mating
Answer: b
Explanation:
Genetic drift refers to these fluctuations in relative allele frequency that may occur more frequently or less frequently throughout time. Rarely occurring alleles are more likely to be lost in small populations, where genetic drift typically takes place. Thus, option B is correct.
What frequency of genes in the gene pool affect migration?Migration impacts the genetic makeup of the resident population to a greater or lesser extent, depending on the amount of migration and the difference in allele frequencies between the resident and migrant populations.
Therefore, A major factor in changing the frequencies of the genes in the gene pool of a population is migration. Gene flow is the movement of alleles through human migration from one group to another.

4. Why should patients with infections be urged to complete their prescribed course of antimicrobial drug treatment?
Answer: Anti-microbial drugs are those which are given to the patient to eradicate, reduce the abundance of pathogen inside the body of the patient either completely or limit the population to limit its infectious effects.
Explanation:
It is necessary to take the anti-microbial drug in according to the dose and tenure prescribed by the doctor as doctor or medical practitioner knows the tenure of the activity of the drug in the body required to kill and reduce the effect of the pathogen in the body completely. The intake of complete dose of the antimicrobial drug will help in killing the bacteria and will also prevent it from multiplying in the body hence will help in reducing the symptoms developed by the pathogen in the body this will help in recovery of the patient.

A student wants to use western blotting to confirm the presence of human Sonic hedgehog (Shh) in samples run on SDS-PAGE and transfered to a nitrocellulose membrane. The antibody reagent box in their lab contains Mouse anti-Shh MAb and Chicken anti-mouse IgG-HRP. What substrate will they need in order to perform colorimetric detection of Shh on their western blot
Answer:
BCIP/NBT
Explanation:
BCIP/NBT is a colorogenic substrate used for AP. AP stands for alkaline phosphatase. When they are catalyzed with this alkaline, we would have a product that has a dark blue or probably a purple color. NBT stands for nitro blue tetrazolium. Both of these work as substrate for the reaction. BCIP oxidizes BCIP to form this color.

Answer:
it may affect the animals and other tree's.
Explanation:
it may affect animals because since it is a new tree, you might not know that it may be harmful for some animals, like maybe the berries the produce are poisonous or fruits some animals are forbidden to eat. this may be a problem because some animals may accidentally eat that fruit and possibly be injured or die.
trees need sunlight and food, if another tree hopes in suddenly there would be more competition for sunlight and water, there may also be not enough water and sunlight for all the trees to share. this is a problem because if the trees can't get enough sunlight and water, they would die and this leads to a broken home for the animals living in that tree.

Speckled trout and red drum both prey on mullet along the Texas coastline. Dead zones are caused by excessive nutrient pollution, along with other factors that deplete the oxygen from the water. What likely effect would increasing dead zones have on the populations of speckled trout, red drum, and mullet?
Answer:
All Three Populations Would Decrease
Explanation:
Dead zones have little to no life in them, and besides the fact that this would mean the popoulations of all of them would just be down because of this, mullet will die out due to nothing to feed on, which will make drums and trout also die out, so all of the populations would go down.
The effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.
What do you mean by Prey?Prey may be defined as an animal that is hunted and killed by another for food.
Dead zones lead to a decline in biodiversity of that area, due to the excessive nutrient pollution and depletion of oxygen. If the members of mullet species get reduced in an environment, species of speckled trout and red drum feel the shortage of food, and hence they also get eliminated or die from the surrounding.
Therefore, the effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver.
a. True
b. False
Answer:
The correct answer is A. The statement is true.
Explanation:
Muscle obtains ATP from glycolysis. When exercise conditions are anaerobic, glucose is degraded to lactate. Lactate is exported into the circulation and is taken up by the liver. The liver synthesizes glucose again from lactate via the gluconeogenic pathway. These two metabolic pathways that allow the coupling of the function of two tissues is what is known as the Cori cycle. The energy cost is 4 P bonds / each glucose that travels both glycolytic-gluconeogenic pathways.
For each of the following terms related to regulation of the cell cycle, briefly describe how that term functions in normal cells. Then, describe how that term may be disrupted in the context of cancer cells. a. density-dependent inhibition i. normal cells – ii. cancer cells – b. anchorage dependence in. normal cells – ii. cancer cells – c. growth factors i. normal cells – ii. cancer cells
Answer:
- Density-dependent inhibition refers to the mechanism by which cells limit their density due to cell-cell contacts. Cancer cells may not undergo density-dependent inhibition, while normal cells exhibit density-dependent inhibition.
- Anchorage dependence refers to the mechanism by which cell stop their division after they form a single layer on a substrate. Cancer cells may not undergo anchorage dependence and therefore they continue to divide, while normal cells undergo apoptosis (programmed cell death)
- Growth factors are signaling molecules (often proteins and peptides) that promote cell division. Overexpression of these factors may lead to carcinogenesis (i.e., the proliferation of cancer cells), while the expression of these factors is normal in normal cells.
Explanation:
Density-dependent inhibition is the mechanism exhibited by normal cells which stops cell division once a threshold density value is reached. In general, cancer cells lost the density-dependent inhibition of growth and therefore they continue dividing. Anchorage dependence refers to the increase in the proliferation of cells that are attached to a solid surface. Most normal cells display anchorage dependence and therefore they need contact with a solid surface to proliferate, while cancer cells are independent of this attachment, proliferating and invading tissues (metastasis). Finally, growth factors are molecules capable of stimulating cell proliferation and cellular differentiation. In consequence, overexpression of growth factors may lead to cancer due to the uncontrolled division of cancer cells. Some examples of growth factors are Epidermal growth factor (EGF), Fibroblast growth factors (FGF) and Vascular Endothelial Growth Factor (VEGF).

Answer and Explanation:
Hormones are substances that administer the human body having several different and essential functions for the proper functioning of the body. There are several different types of hormones and they are classified into four groups called peptides, steroids, amines and eicosanoids.
Peptides are hormones that have 3-20 amino acids. Among these hormones we can mention insulin, glucagon and somatostatin.
Steroids are hormones produced from cholesterol. Among them we can mention Cortisol, Aldosterone and Testosterone.
Amine hormones are those that are released into the thyroid and adrenal glands. These hormones circulate freely in the blood. Among them are epinephrine and norepinephrine.
Eicosanoids are the hormones derived from arachidonate. Among them are the hormones called prostaglandins, thromboxanes and leukotrienes.

An increase in heart rate will most likely result in
O (1) a decrease in metabolic rate
O (2) an increase in pulse rate
O (3) an increase in cell division
O (4) a decrease in body temperature
Answer:
O (2) an increase in pulse rate
An increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).
What is Heart?Heart is a fist shaped organ which pumps blood throughout your body present in the centre of the chest tilted slightly towards the left. It is the primary organ of the circulatory system which pump blood around the body as the heart beats. The blood sends oxygen and nutrients to all parts of the body and carries away unwanted carbon dioxide and waste products from there.
Heart has four chambers (lobes) made up of muscles- two on the left side and two on the right made up of three layers of tissue -epicardium, myocardium and endocardium. These layers are surrounded by the pericardium which a thin outer lining protecting the heart.
It circulates abut 5-8 liters of blood. Heart, blood and blood vessels together make the cardiovascular system. Blood is pumped around your body through a network of blood vessels- Arteries, Capillaries and veins. Heart has four valves which act like gates which keep the blood moving in the right direction.
Thus, an increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).

Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.
