A. Independent Variable=
B. Dependent Variable=
C. Control=

Answers

Answer:

it is an independent variable as it can be changed by studying and also a dependent variable as you can measure her results and see its increase or decrease

Explanation:

hope this helps

could u pls help me with my latest questions pls pls pls pls pls

The variables in the given situation would be as follows:

A). Independent Variable: Amount of time given on study

B). Dependent Variable: Grade in Science

C). Control: Additional Study of 30 minutes

In an experiment or research, an independent variable is described as a variable that remains unaffected by the change in other but rather a manipulation or change in it can affect the other variables. Dependent variables are the variables that receive a direct effect of change in the other variable and therefore, it is the variable that the researcher aims to measure or study.While control helps in making the comparison of the results with or without it. Thus, the given variables are classified in this situation as mentioned above.

Answer:

[tex]\boxed {\tt D. \ Denaturing \ the \ enzyme }[/tex]

Explanation:

Enzymes are special proteins that speed up chemical reactions. They have specific shapes that correlate to their functions. They also have optimal temperature and pH ranges. They should be in the range for the best results.

If an enzyme is placed in an extreme temperature or pH, the enzyme will become denatured. The enzyme will fold in a different way and its unique shape will be altered. As a result, the enzyme will slow down or stop working.

Therefore, the correct answer is D. denaturing the enzyme.

Answers

Answer:

mitochondria contain membrane folds called cristae, whereas chloroplasts contain vesicles in stacks called grana

Explanation:

Mitochondria are composed of two membranes (i.e., the inner and outer membranes), which are separated by the intermembrane space. The inner mitochondrial membrane is composed of several folds that form the cristae, which extend into the mitochondrial matrix. On the other hand, in chloroplasts, the inner membrane consists of interconnected stacks of sacs named thylakoids, whose arrangement is known as grana.

Which of the following statements concerning ribosomes is true?
A. Several ribosomes are often attached to and translating the same MRNA.
B. Ribosomes join amino acids together to form a polypeptide.
C. Ribosomes have one binding site for MRNA and three binding sites for 1RNA molecules.
D. Ribosomes are the organelles responsible for protein synthesis.
E. All of the above statements are true.

Answers

Answer:

E. All of the above statements are

Explanation:

Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.

A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).

Ribosomes are complicated macro molecules composed up of nucleic acids and proteins. They are important as they perform a major role in protein assembly and transportation.

The correct answer is:

Option E. All of the above statements is true.

The explanation for the above option is:

The ribosome is located either free or is connected to the endoplasmic reticulum(RER).

Ribosomes assist in the translation of the information from mRNA.

Polysomes are numerous ribosomes connected to a single mRNA molecule.

Ribosomes have one binding position for mRNA and three binding positions for tRNA molecules.

The three binding sites for tRNA is (A- site) amino acyl site, (P-site) peptidyl site and (E site) the exit site.

Ribosome assembles amino acids to form a polypeptide chain. These polypeptides get transported to the cytoplasm.

Therefore all the above statements are true for ribosomes.

Answer:

A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails. ” The phosphate group is negatively charged, making the head polar and hydrophilic, or “water loving.” The phosphate heads are thus attracted to the water

Age structure diagrams show the distribution of people of various ages. The diagrams also show the number of people in the prereproductive, reproductive, and postreproductive years. Research and note what else you can infer from age structure diagrams.

Answers

Answer:

Age structure diagrams show the following.

The height of the graph indicates life expectancy.

The width of the base shows birth and fertility rate.

The slope of the pyramid-shaped diagram indicates death rate.

Bends in the graph indicate reductions in birth rate or increases in

death rate.

The overall shape of the diagram indicates whether it is an economically developed country or not.

Explanation:

In a stable human population, the age structure diagram looks like a pyramid with a narrower base. The narrower base depicts that the birth rate is low. A stable human population also has a high number of older individuals. A greater number of older people in a population shows that quality of life is high in that area/country and the population has access to nutritional diet, medical care, and healthcare services. These features of the age pyramid in a stable population indicate a developed country. Age pyramids of underdeveloped countries have a wider base (high birth rate) and narrow tip.

The answer to the question is true

Yes, Your white blood cells account for only about 1% of your blood, but their impact is big. White blood cells are also called leukocytes. They protect you against illness and disease. Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness.

Answers

Answer:

DNA unzips between base pairs.

Explanation:

This is the first step of protein synthesis.

The first step of protein synthesis is attachment of mRNA to ribosomes. Option A is correct.

Protein synthesis:

It is known as translation. In this mRNA is translated in to the sequence of amino acids which ultimately form protein.

First mRNA attach to ribosome,tRNA bring amino acid to ribosomes and attach to mRNA.Amino acids bond together via peptide bond.
