Which of the following is mostly likely to result from an error during transcription A. it is formed by a particular sequence of amino acids B. it is read in groups of three nitrogenous bases C. it is made of the same components in all living organisms D. it is found in the base sequence of nucleic acids
Answer:
So I think you're trying to ask where transcription errors take place, which I would say is A.
Explanation:
DNA transcrption is when DNA is converted to RNA, which is then sent to ribosomes in the cell to make specific protiens(this is how viruses destroy cells, they use this system to make more viruses by causing viral RNA or DNA(transcripted)to be given to ribosomes) Anyway, transcritpion makes certain sequences of Amino acids for protiens, so an error is going to affect this area first, which can cause large systematic problems later.

A person can eat when hunger is absent because: a. the conscious mind of the cortex can override the body's signals b. the digestive tract sends messages to the hypothalamus c. the hypothalamus signals the availability of food in the environment d. the stomach intensifies its contractions and creates hunger pangs e. the glands start supplying epinephrine to the brain
Answer:
a. the conscious mind of the cortex can override the body's signals
Explanation:
Physiologically the satiety center in the hypothalamus control hunger is the lateral hypothalamus,while the ventral hypothalamus ensures satiety,urge to stop eating.Therefore the sensation to eat is involuntary. Mammalian brain is made up of the higher brain centers,located in the Cerebral cortex. These are regions of the brain used for judgemental cases,and conscious reasons to meet the demand for immediate needs.
Once the urge of thirst and hunger has been met,the satiety center stimulation is stopped.However,if one wishes to eat despite the stimulation of the hunger center,The crave for this is control by the conscious cerebral cortex,which allow the person to make the decision,without the involuntary region of the brain.
Hence the need to it is no longer done for nourishment,but rather to meet up or carried out the habits of fulfilling the passion to eat.
A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all.
Answer:
C
Explanation:
The complete question: A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all. In the experiment described in the scenario, which group represents the control group? A. Plant B B. Plant A C. Plant D D. Plant C?
The control group here would be plant D.
Control groups are usually used to minimize the effects of extraneous variables in the course of experiments and to ensure that the differences observed in different experimental groups are due to the effects of the independent variables.
In this case, all the plants were exposed to music except the control group because the aim of the experiment is to measure the effects of music on plant growth. Any difference in growth observed between those exposed to music and the control group can reliably be considered to be due to the music.
The correct option is C.

A rabbit breeder has rabbits that exhibit three different coat colors: dark gray, chinchilla (a lighter gray), and albino. When cross breeding rabbits with these different coat colors, he finds that dark gray is dominant to chinchilla and albino, whereas chinchilla is dominant to albino. These phenotypic outcomes indicate that there are more than two alleles of rabbit coat-color genes and that they exhibit
Answer:
Multiple allelism
Explanation:
Multiple alleles occur whereby three or more alternative form of a gene which in this case study are dark gray, chinchilla (a lighter gray), and albino; are all present at a locus but only two of the alleles can be present in just one organism.
Trace what happens to a piece of bread as it enters the mouth to the large intestine. Be sure to mention each organ of the digestive system and what happens to the bread in each part. ( can you put it in high school level)
Answer:
Bread is a carbohydrate.
Digestion of carbohydrates begin from the mouth.
As the bread is eaten and it is been chewed, the salivary amylase act on it.
This is also called mastication which is the breaking down of large pieces of bread into smaller pieces.
The salivary amylase break the monomeric bond between the dissacharides and starches by breaking amylose and amylopectin into smaller glucose.
When it's get to the stomach there is no further breaking down in the stomach because amylase do not get to the stomach because of stomach acidity. The strong peristaltic contraction of the stomach make it to form uniform chyme.
When the chyme entered the small intestine, the pancrease releases the pancreatic juice which contain amylase that breakdown dextrins into shorter carbohydrates. Additional enzymes are released which break maltose into two glucose and this enzyme is called maltase.
Sucrase breakdown sucrose into glucose and galactose.
There are cells in the small intestines which contain membranes that have protein transport which get monosaccharides and other nutrients to be absorbed in the blood.
The liver receive glucose, fructose and galactose and store them which is later use by the cells.
Explanation:
Digestion is the breakdown of large complex food into smaller pieces which can be easily absorbed by the body.
The goal of carbohydrates digestion is to breakdown complex carbohydrates and dissacharides into monosaccharide that can be absorbed into the body.

Which is one place that glaciers are found?
A) in the ocean
B) in the tropics
C) at low altitudes
D) at high latitudes
Answer:
I believe it is at high latitudes
Explanation:
I say this because many glaciers are found in Greenland and Antarctica which are both located in higher latitudes
Glaciers are found at HIGH latitudes (Option D).
Latitude refers to the geographic coordinates which are used to indicate specific north-south positions on the Earth's planet.
Low latitudes are geographic coordinates found between the 0 degrees (Equator) and 30 degrees north-south, whereas high latitudes are found between 30 degrees and 90 degrees north-south positions.
At low latitudes, the energy from the sun is able to melt the polar ice.
Thus, glaciers are found at high latitudes because the highest latitudes get a minor amount of energy from the sun compared to low latitudes.
In conclusion, glaciers are found at HIGH latitudes (Option D).

A student is collecting the gas produced
from the reaction of 1.5 grams of Mg with
excess HCI. When the reaction is
complete, how many moles of H2 should
have been produced?
Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.

Gastroparesis is a condition that causes a partial paralysis of the stomach. The stomach has reduced ability to contract to move food through the digestive system. Some common symptoms of gastroparesis are abdominal pain, nausea, and feeling full after eating a small amount of food. What would be the most likely cause of this condition? A. damage to nerves that control the stomach B. lack of pancreatic juices and bile C. lack of enzymes in the small intestine D. damage to the mucus lining of the stomach
Symptoms of this condition include paralysis of the stomach muscles. Muscles are controlled by nerve impulses, therefore the most likely cause for this condition is (A.) damage to nerves that control the stomach
B. lack of pancreatic juices and bile -> this will lead to food not being chemically brokend down properly in the stomach and oils not mixing with water leading to malnutirion
C. Lack of enzymes in the small intestine -> this will also lead to food not being chemically digested and malnutrition
