A recent clinical study demonstrated a possible connection between coffee consumption and heart health. The researchers performed
a 6-week trial with 191 individuals, all of whom were heavy coffee drinkers (average of 5 cups/day) prior to the experiment, but none of
whom were smokers. They divided the 191 participants into three groups: no coffee consumption, 1-3 cups/day, and 4 or more
cups/day. They measured blood levels of cholesterol and homocysteine as indicators of heart health Only the no-coffee group showed
a significant drop in both indicators. Previous studies had demonstrated that decreases of the magnitude observed in the no-coffee
group could cut the incidence of heart disease by 10-15%.
a) What is the problem/question being studied?
b) What is the hypothesis?
c) What is the experimental variable?
d) List the controls
e) What is being measured to test the hypothesis?​

Answers

Answer 1

Answer:

The summary as per the issue is summarized in the following portion of the clarification.

Explanation:

(a)

The association regarding coffee intake and insulin sensitivity is being tested and the results. This procedure is intended to examine whether unnecessary coffee intake is positive or negative again for the heart. Or if there are any cardiovascular problems it may induce.

(b)

The hypothesis seems to be the consequence of such a hypothesis. This illustrates inside such an outcome the association between the factors and response variable. It is stated to provide an understanding of the experiment's response.

(c)

Any conditions that may be adjusted, calculated, or influenced during an analysis constitute variables. Three research variables have become primarily present. Variable autonomous, variable dependent including variable power. They are those variables that can only be modified in an experiment by a researcher. Independent variables are essentially the cause for the effect, as well as a shift of independent variables impacts the variables (dependent) accordingly.The independent variable throughout this analysis is the number of coffees, in which 3 categories are given separate amounts of cups of coffee. The researcher decides the coffee which should be offered to all the participants.

(d)

Through an analysis, monitoring variables are those variables most of which are maintained stable. Variables under regulation throughout this experiment include body temperature, ambient moisture.

(e)

To verify the theory, the ratio of cholesterol including homocysteine throughout the blood would be calculated. The theory indicates that a rise in cholesterol levels, as well as homocysteine levels, can be caused by increased coffee intake, thus raising their risk of cardiovascular diseases.

The main difference between the water cycle and the other chemical cycles is that water



never changes its structural form (H2O) .


is much slower than the other cycles.


creates completely new substances.


is made from matter that has been here since the world was formed.

Answers

Answer:

The answer is A.

Explanation:

Other cycles change their structural form often, but water does not change it's structural form in the water cycle, which is H2O so that is one main difference between the water cycle and oither checmical cycles. So, your answer is A.

The main difference between the water cycle and the other chemical cycles is that water never changes its structural form (H2O). Thus, the correct option for this question is A.

What is the water cycle?

The water cycle may be defined as a type of biogeochemical cycle that significantly involves the gradual and continuous movement of water and its derivative products within the Earth and atmosphere.

The water cycle remarkably consists of three major processes. They are as follows:

Evaporation: a process through which a liquid converts into gas.Condensation: a process through which gas converts into liquid.Precipitation: a process through which liquid water falls on the earth's surface.

The most important concept of the water cycle is that the structural form of water remains constant and the same throughout the process. This property of water differs from other chemical cycles because such cycles involve the alteration in their fundamental component.

Therefore, water never changes its structural form (H2O) is the main difference between the water cycle and the other chemical cycles. Thus, the correct option for this question is A.

Explanation:

Which would probably have the greatest effect on a protein's function—a change to the primary, secondary, or tertiary structure? Explain your answer.

Answers

Answer:

There are 20 different standard L-α-amino acids used by cells for protein construction. Amino acids, as their name indicates, contain both a basic amino group and an acidic carboxyl group. This difunctionality allows the individual amino acids to join in long chains by forming peptide bonds: amide bonds between the -NH2 of one amino acid and the -COOH of another. Sequences with fewer than 50 amino acids are generally referred to as peptides, while the terms, protein and polypeptide, are used for longer sequences. A protein can be made up of one or more polypeptide molecules. The end of the peptide or protein sequence with a free carboxyl group is called the carboxy-terminus or C-terminus. The terms, amino-terminus and N-terminus, describe the end of the sequence with a free α-amino group.

The amino acids differ in structure by the substituent on their side chains. These side chains confer different chemical, physical, and structural properties to the final peptide or protein. The structures of the 20 amino acids commonly found in proteins are shown in Figure 1. Each amino acid has both a one-letter and three-letter abbreviation. These abbreviations are commonly used to simplify the written sequence of a peptide or protein.

figure1-Protein-Structure

Depending on the side-chain substituent, an amino acid can be classified as being acidic, basic or neutral. Although 20 amino acids are required for synthesis of various proteins found in humans, we can synthesize only ten. The remaining 10 are called essential amino acids and must be obtained in the diet.

The amino acid sequence of a protein is encoded in DNA. Proteins are synthesized by a series of steps called transcription (the use of a DNA strand to make a complimentary messenger RNA strand – mRNA) and translation (the mRNA sequence is used as a template to guide the synthesis of the chain of amino acids which make up the protein). Often, post-translational modifications, such as glycosylation or phosphorylation, occur which are necessary for the biological function of the protein. While the amino acid sequence makes up the primary structure of the protein, the chemical/biological properties of the protein are very much dependent on the three-dimensional or tertiary structure.

A change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

The primary structure of a protein refers to the linear sequence of amino acids within a polypeptide chain.

A change in the protein primary structure will change protein properties and likely will also alter their functions.

The secondary structure of a protein refers to the specific arrangement of groups of amino acids. The most common types of secondary structures in proteins include alpha helix and beta sheets.

The tertiary structure refers to the three-dimensional shape of the protein. There are two major main classes of protein tertiary structure: fibrous and globular.

The quaternary structure refers to the association of different protein subunits to form a multimeric protein.

In conclusion, a change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

the molecule that is formed as a result of the acceptance of hydrogen ion and the final acceptor molecule.

Answers

Answer:

H2O (Water)

Explanation:

Oxygen (O2) is the final acceptor molecule after the process of aerobic respiration. Specifically, it accepts hydrogen ions at the end of the electron transport chain, the main energy-generating stage of cellular respiration.

This is why oxygen is needed to form large amounts of cellular energy, as without it, the electron transport chain cannot proceed. When oxygen accepts hydrogen ions, it forms water, a byproduct of aerobic respiration.

The cell membrane serves many functions. One of the cell membranes functions is to help the cell maintain homeostasis. How does the cell membrane do that ?

Answers

Answer:

The cell membrane help to maintaining homeostasis by regulating the flow of substances through it and by recognizing potentially harmful agents to the cell.

Explanation:

Cellular membrane is constituted by a lipidic bilayer, whose characteristics allow it to behave as a semi-permeable membrane to the passage of substances.

The selective permeability of the membrane makes it possible to regulate the passage of water, molecules and ions through it into the cell and from there into the extracellular space, a characteristic that allows the maintenance of homeostasis.

Additionally, the cell surface can identify foreign and potentially harmful agents, which can affect the internal balance, preventing in most cases their passage into the cell.
