The best description of the bonds that form polypeptides and the difference between polypeptides and proteins is.

Answers

Answer 1

Answer:

Explanation:

A peptide is two or more amino acids joined together by peptide bonds, and a polypeptide is a chain of many amino acids. A protein contains one or more polypeptides. Therefore, proteins are long chains of amino acids held together by peptide bonds.

hope this helps :)

Answer 2

Polypeptides are collections of amino acid chains linked by what are known as peptide bonds. The carboxyl group of one amino acid and the amino group of another amino acid condense, forming these peptide bonds and releasing a water molecule in the process.

The size and complexity of polypeptides and proteins primarily differentiate them from each other. Polypeptides are amino acid chains that are usually less than 50 amino acids long. On the other hand, proteins are larger and more complex molecules made up of one or more polypeptide chains folded into certain three-dimensional (three-dimensional) structures known as tertiary and quaternary structures of proteins .

EXPERIMENT: MASS OF GAS
Here is your goal for this lesson:

Write a report on the mass of gas

We often do not think of gas in terms of having mass. The atmosphere is something we live in and breathe. In this experiment, we will investigate whether gas does truly have mass.

Hypothesis: If gas does indeed have mass, then different volumes of it will have a different mass. This could be demonstrated by using a simple balance and comparing the two different volumes, captured by means of balloons.

Materials needed:

two balloons of the same size
meter stick
string
paper clips

Procedure:

1. Suspend the meter stick from the middle in such a way as to be able to move the string to balance. See the diagram below.



2. Attach each balloon to either end of the meter stick, making the apparatus balance.
3. Blow up each balloon to different volumes, thus measuring out different volumes of gas.
4. Attach the balloons as shown in the diagram below using the paper clips. Be careful to attach the balloons in the same place as where the apparatus balanced.



5. Answer the following questions in the writing space provided in this assignment.

Did the suspended balloons balance?
If they did not, which balloon tipped the scale down?
Did your results validate the hypothesis?
Give an explanation for your results, including a discussion of how the data collected either validated, or disproved the hypothesis.

Answers

The suspended balloons did not balance. The bigger balloon tipped the scale down. And yes, it validated the hypothesis that gas does have mass, as the bigger balloon weighed down the scale.

Gases have mass. Gas particle gaps are completely empty. Chemical reactions can produce gases as a byproduct. Under some circumstances, bonding between gas atoms is possible.

Loosely packed molecules can be found in gases. Gases have weight because the molecules that make them up have mass. Because of this, a balloon with air inside weighs more than one with none.

After combining the vinegar and baking soda, one of the paper bags will be "poured" with gas from the pitcher, which will cause the scale to tip toward that end even though nothing actually was poured into the bag. It is demonstrated by this that gas has mass and is heavier than oxygen.

The development and spread of a new gene for antibiotic resistance in a population of bacteria that are exposed to that antibiotic would mean that trait is a(n) adaptation.

In the field of biology, an adaptation can be described as a particular feature or characteristic that allows an organism to survive in an environment.

Organisms that can better adapt to changing conditions are more likely to survive and reproduce.

When a colony of bacteria incorporates a gene for resistance against a certain antibiotic, then this action is an example of an adaptation of the bacterial colony. The bacteria can now grow in that antibiotic medium because they have antibiotic resistance gene for it. This makes the bacterial colony more adaptable to survive in the antibiotic medium.

The graphs below show the effect of light intensity on the rate of photosynthesis at different carbon dioxide concentrations.Explain what the graphs show.

Answers

The rate of photosynthesis rises as light intensity does (point B on the graph). Thus, there is a greater intake of carbon dioxide. This rise in carbon dioxide uptake is depicted on the graph.

What effect of light intensity on the rate of photosynthesis?

As long as other variables are abundant, photosynthesis will proceed at a faster pace as light intensity rises. Another element will eventually become scarce as the rate rises.

Water and carbon dioxide are converted by photosynthetic pigments using light energy into carbohydrates and oxygen.

Greater starch reserves and enhanced auxin biosynthesis may result from leaves containing more non-structural carbohydrates due to increased photosynthesis.

From the big bang theory, after cooling the debris, allowed the formation of the following

Answers

Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.

What is big bang theory?

The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.

Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.

The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.

By releasing chemicals known as hormones and neurotransmitters, respectively, as a form of communication, the endocrine and neurological systems both regulate, coordinate, and integrate many physiological processes and bodily activities. A stimulus activates the neurological and endocrine systems, which then send messages and produce responses.

The endocrine and neurological systems are different:

Endocrine glands secrete hormones that act for a much longer period of time than the neurological system's ability to produce a neural response. Hormone action moves more slowly than neuronal response. A nerve or neural impulse may move through the body almost instantly and in a matter of seconds.

While the neurological system employs electrical impulses to transfer signals across neurons for signaling pathways, the endocrine system uses chemical signals or hormones to accomplish so. The neuronal reactions are transient and reversible, whereas the hormonal impulses are permanent.
