Answers

Answer 1

Answer:

hypothesis is A hypothesis (plural hypotheses) is a precise, testable statement of what the researcher(s) predict will be the outcome of the study.

Explanation:

independent variable is what u can change

dependent variable is the one u can measure

control variable is one u keep the same

control treatment In the design of experiments, treatments are applied to experimental units in a treatment group. In comparative experiments, members of a control group receive a standard treatment, a placebo, or no treatment at all. There may be more than one treatment group, more than one control group, or both

experimental treatment in research, the conditions applied to one or more groups that are expected to cause change in some outcome or dependent variable.

What is the brain?

The brain is the most important part of the body. It controls and runs all functions of the body. It is walnut shaped and present in the head of the body. The brain is divided into two hemispheres. The left and the right hemisphere.

The brain is also divided into frontal and parietal lobes. The frontal lobe is present in the front section, and it controls social interaction, problem-solving, motor functions, etc.

So if the frontal lobe will be affected, the social behavior also gets affected and the person becomes irritable and aggressive.

Thus, the correct option is D, antisocial and aggressive behavior.​

Which of these changes to the cell would cause the greatest reduction in the activity of the catalase?

CHOICES:
#1 a return of pH to the normal range

#2 A decrease in the concentration of hydrogen and oxygen

#3 an increase in the concentration of hydrogen peroxide

#4 an increase or decrease in PH beyond normal range​

Answers

Answer:

#3 an increase in the concentration of hydrogen peroxide.

Explanation:

The changes to the cell that causes the greatest reduction in the activity of the catalase would be - #3 an increase in the concentration of hydrogen peroxide.

Catalase enzyme is present in both plant and animal cells. The catalase is mainly found in aerobic organisms. The substrate for the enzyme is hydrogen peroxide which is broken down into oxygen and water.

The hydrogen peroxide is harmful to the cell and very reactive. Its buildup can kill the cellto breakdown the hydrogen peroxide, the catalase enzyme catalyzes it and convert it into water and oxygenincrease of the hydrogen peroxide leads to a reduction in the activity of the catalase.A single molecule of the catalase can break down 40 million molecules of hydrogen peroxide per minute.

Thus, the correct answer is - #3 an increase in the concentration of hydrogen peroxide.

The human body can be divided into three planes on the basis of anatomy - the sagittal plane, the coronal plane, and the transverse plane

A sagittal plane is a longitudinal plane that divides the human body in the left and right parts.

A coronal plane is an anatomical plane that divides the body vertically into the back and front, ventral or dorsal (to be more specific).

An Axial or transverse plane, it is the plane that divides in the upper part of the body and lower part of the body.

When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity?
a) the ions in the solution interact with the sugar and that interferes with its solubility
b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not
c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water

Answers

Answer:

c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules

Explanation:

A solution contains a solvent (water in this case) and a solute (sucrose in this case). A solution can either be saturated or unsaturated depending on whether it can still dissolve a solute or not.

According to this question, the 0.7 M sucrose solution does not dissolve the sucrose (solute) any longer. This implies that the sucrose solution is getting SATURATED. The saturation of the sucrose solution occurs because the amount of solutes is equating the amount of solvent in the solution.

The solubility of a solution depends upon polarity. The solute molecules (sucrose) adhere to the polar regions of the water molecules (solvent). When this occurs to the point where no other sucrose molecule can adhere, the solution becomes SATURATED so there is no room for more sucrose molecules.

Answers

Hello. This question is incomplete. The full question is:

A tRNA anticodon is 5' GAA 3'.

Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'

Answer:

a) 5' UUC 3'

Explanation:

Anticodons are sequences of nitrogenous bases that establish complementarity with sequences of nitrogenous bases in a codon.

As you know, mRNA has the nitrogenous bases Adenine (A), cytosine (C), guanine (G) and uracil (U). In this system, guanine is supplemented with cytosine and adenine is supplemented with uracil.

These bass are organized into codons, which are a set formed by 3 of these bases.

The tRNA has the same bases, but its codons must recognize and complement the codons of the mRNA, being then called Anticodons.

In this case, if a tRNA has the anticodon 5 'GAA 3', it must bind to codons 5 'UUC 3' in the mRNA.

Answer:

A. Based on our results, students who do 1 hour of chores per night

have grades that are on average 0.2 points higher than students

who do no chores.

Explanation:

In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.

From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.

The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.

A good example of muscular exercise is push up the ability to constantly do it for a long time without rest or stopping.

The push-up is the most appropriate exercise for testing muscular endurance. Therefore, the correct option is A.

Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions over a prolonged period of time.

The push-up specifically targets the chest, shoulders, triceps, and core muscles. It requires maintaining a plank position and lowering and raising the body by bending and extending the elbows.

By performing as many push-ups as possible without compromising form, an individual can assess their muscular endurance level.
