When comparing proteins and polysaccharides, the following similarities
can be identified: *
Both consist of linked monomers via the process of dehydration reactions.
O Both consist of linked monomers via the process of hydrolysis.
O Both consist of linked sugars via the process of dehydration synthesis.
O O
Both consist of linked amino acids via the process of hydrolysis.
Answer:
The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.
Explanation:
Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.
The process of polymer formation is called polymerization, and one of the reactions that this process allows is polycondensation, where a water molecule is lost in the union of monomers.
The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.
The other options are not correct, because
Hydrolysis produces the rupture of molecules, with the intervention of water.Only polysaccharides are sugars bound by the dehydration synthesis process.Only proteins consist of amino acids linked through the process of hydrolysis.Choose the best definition for the vocabulary term: Specificity

A population of mice in a field contains 5000 individuals at the beginning of a study. During the course of 1 year 2500 new individuals are born and 1000 individuals die, such that the population size after 1 year is 6500. Assuming that annual per capita birth rate (b) and per capita death rate (d) do not change, what will the population size be after another year has passed
Answer:
The population size would be of 8,450 mice.
Explanation:
While the initial population of mice was 5,000 and there were 2,500 new births, the birth rate is 50% (2,500 / 5,000 = 0.5). Now, the 1,000 deaths, in turn, represent a mortality rate of 20% (1,000 / 5,000 = 0.2). In this way, at the end of the year, the number of mice became 6,500 (5,000 - 1,000 + 2,500).
Maintaining the same population growth rates, the number of new births would be 3,250 (6,500 x 0.5), and the number of deaths would be 1,300 (6,500 x 0.2), with which at the end of the second year the number of mice would be 8,450 (6,500 - 1,300 + 3,250).
DNA molecule has 100 cytosine 850 thymine base write the base pair
Answer:
cytosine always pairs with guanine and it always have the same molecule
so, if cytosine is 100, guanine is also 100
thymine also has the same number of molecules as adenine cuz it pairs together
so, if thymine is 850, adenine is also 850
total-->200+1700=1900

stay safe from the virus
Explanation:
A classmate tells you that comic books are full of superheroes with powers caused
by mutations. Therefore, all mutations must be beneficial. Decide whether or not you agree. Write a
paragraph to argue your position regarding the benefits or harm caused by mutations.
Answer:
No because that is just one example, and a completely fictional example at that, used for entertainment.
Explanation:
Mutations could cause health problems and abnormalities that could prove fatal. Though there could be benefits, like immunities to diseases, inherited or contracted, just the opposite could happen as well. And even if some benefits could be gained, a whole new set of problems could result from that change that weren't there before.

Like DNA, RNA contains four nitrogenous bases.
Three of them are the same as those found in
DNA. The one that is different is called
The five-carbon sugar in RNA is called
DONE
Answer:
1. Uracil
2. Ribose
Explanation:
DNA and RNA are both types of nucleic acids. Although they are made up of similar constituent molecules, they are slightly different. All nucleic acids have three major constituents viz: nitrogenous base, pentose sugar and phosphate group.
The four nitrogenous bases found in DNA are Adenine, Guanine, Cytosine and Thymine. However, three of this bases are found in the RNA molecule but one different one called URACIL, which replaces Thymine is found. Also, the pentose (five-carbon) sugar found in DNA is deoxyribose while that of RNA is RIBOSE.
where stem cells transform to T cells
Answer:
Scientists from the UCLA AIDS Institute and the Institute for Stem Cell Biology and Medicine have derived T-cells from human embryonic stem cells, raising hopes for a gene therapy to combat AIDS. The Proceedings of the National Academy of Sciences reported the findings in its July 14, 2006, online edition.
“We may be able to use human embryonic stem cells to treat T-cell and other blood diseases,” says lead author Zoran Galic, assistant research biologist. “This could be a very important weapon in the fight against AIDS.”
The researchers cultured human embryonic stem cells and incubated them on mouse bone-marrow cells, which in turn converted them into blood-forming cells. Those cells were injected into a human thymus that had been implanted in a mouse. The thymus transformed the bloodforming cells into the T-cells that HIV targets for destruction.
“Our results indicate that it’s possible to decipher the signals that control embryonic stem cells’ development into mature T-cells,” says Jerome Zack, associate director of the UCLA AIDS Institute and professor of microbiology, immunology and molecular genetics. “This way we can eventually repopulate the immune system of patients needing T-cells.”
One of the body’s main defenses against disease, Tcells are manufactured in the thymus. The organ shrinks as we age, weakening the immune system. The scientists anticipate that their findings could give rise to gene-therapy approaches for other diseases related to T-cells such as severe combined immunodeficiency, or “bubble-boy disease.”
Explanation:
Explanation:
T cell progenitors originate in the bone marrow and, through a series of defined and coordinated developmental stages, enter the thymus, differentiate, undergo selection, and eventually mature into functional T cells.
The sensor or detector tells the integrating center what needs to be done
True
False
Answer:
True
Explanation:
It is true because a sensor or detector is an organ that detects external stimuli from the environment or changes in both internal and external environment, it then send the information to the integrating center.
The integrating center receive stimulus or information from sensor and activate responses to the stimulus.

Describe the energy transformation that takes place as the roller coaster moves up the hill and explain how each form of energy changes.
Answer:
A roller coaster ride is a thrilling experience which involves a wealth of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor (or other mechanical device) exerts a force on the train of cars to lift the train to the top of a very tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation.
sedimentary igneous and metamorphic rocks are all formed in the same way true or false
Answer:
False
Explanation:
The way they are formed is in the name. Sedimentary are built from layers of materials being compacted over huge timespans. Igneous are formed as lava or magma cools into a solid material. Metamorphic are rocks that are changed from other types of stone due to high heat and pressure in the Earth.
When given an unknown bacterial sample the first step is to expand the current bacterial population. Which type of media best suites this need and Why
A. MSA agar
B. LB media
C. MacConkey agar
D. Columbia CNA agar
Answer:
The correct answer among the given options is - LB media
Explanation:
The type of bacteria is unknown so can not be determined precisely what media should be best for such population however, on the given information the best media would be LB media for this population due to the fact that all other media forms that are selective will inhibit its growth and it is a nutrient-rich medium which favors the growth of bacteria.
Hence, the bacteria population should be placed in LB media for growth and after expanding its growth one should place in its selective media plate.

If there is 24% adenine present in a dna helix how much thymine would be present
Answer:
24 % Thymine (T)
Explanation:
Chargaff's rules indicate that in double-stranded DNA, the proportion of Adenine (A) is equal to the proportion of Thymine (T), while the proportion of Guanine (A) is equal to the proportion of Cytosine (C). Since double-stranded DNA has 24% A, it means there will be 24% T.
Moreover, in this case, the A + T content in the double-stranded DNA is 24 + 24 = 48%, while the G + C content is 48 - 100 = 52%, i.e. G = 26% and C = 26% (26 + 26 = 52).

What are the charges both inside and outside of the neuron before you click the stimulate neuron button?
Answer:
The charges inside and outside of the neuron before receiving a stimulus are negative and positive, respectively, which corresponds to the transmembrane rest potential.
Explanation:
Neuron is the specialized cell of the nervous system in charge of transmitting electrical impulses. The generation of a nerve impulse in the form of an electric current is due to a change in the transmembrane potential.
Outside the neuron cell, electrical charges are predominantly positive, and the ion with the highest concentration is sodium. In the intracellular space, a great quantity of proteins provide negative charge, and there is a predominance of potassium ions. Under these conditions, the ionic channels are closed.
For this reason, a neuron at rest, before receiving a stimulus, presents positive charges on the outside and negative charges on the inside, and the membrane potential in this condition is estimated at a value of -65 mV.
Once a stimulus is produced, the ionic channels open and Na+ ions enter the cytoplasm, exchanging them for K+, which implies a change in the membrane potential which, on reaching the threshold, produces an action potential and the nerve impulse is produced.
