Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.
Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.
A hydrogen bond is a strong dipole-dipole attraction which occurs between:
the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electronsHydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.
When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.
Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

What will be the effect on protein function if each polypeptide adopted only a single, inflexible shape based on its primary structure?
A) The protein ability to catalyze would be impaired. The tertiary structure could not appear, so those proteins could not perform their function.
B) The ability to regulate protein activity would be impaired. The peptide bonds would not be so stable compared to linkages in other types of macromolecules, so those proteins could not perform their function.
C) The ability to regulate protein activity would be impaired. The proteins would be either permanently active or inactive, depending on how they are folded.
D) The proteins would perform their functions normally.
The ability to regulate protein activity would be impaired. The proteins would be either permanently active or inactive, depending on how they are folded (Option C).
Proteins are complex biomolecules composed of linear chains of amino acids that interact to produce a final three-dimensional (3D) protein structure.Protein folding refers to the cellular mechanism by which proteins are folded to render a biologically active protein.Different heat shock proteins (Hsp) are involved in protein folding.If a protein or its subunits are not correctly folded, then it remains inactive because there is no interaction with its corresponding molecular partners (e.g., another protein in protein-protein interactions or DNA in the case of a transcription factor).Learn more in:

Animals perform cellular respiration and photosynthesis, but plants only perform photosynthesis.
Plants and animals perform cellular respiration and photosynthesis.
Answer:
Plants perform cellular respiration and photosynthesis, but animals only perform cellular respiration.
Explanation:
i took a test and it said it was right
Plants perform cellular respiration and photosynthesis but animals only perform cellular respiration. So the correct option is A.
What are photosynthesis and cellular respiration in plants?
Photosynthesis and cellular respiration are both processes that occur in plants. These processes are the reverse of each other.
In the process of photosynthesis, plants use inorganic materials, like carbon dioxide and water to produce their food by the process of photosynthesis. This process uses light energy and it is converted to chemical energy.
Following is the reaction of photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
In the process of cellular respiration, the glucose produced by plants is broken down to produce energy in the form of ATP. ATP is the energy currency of all cells including plant cells. Therefore, plants need to convert their food to ATP in the form of ATP as well.
Following is the reaction of cellular respiration in plants.
C₆H₁₂O₆ + O₂ → CO₂+H₂O+ ATP.
Thus plants perform cellular respiration as well as photosynthesis.
Therefore the correct option is A.

The chemicals in tobacco smoke harm your blood cells. They also can damage the function of your heart and the structure and function of your blood vessels. Atherosclerosis is a disease in which a waxy substance called plaque (plak) builds up in the arteries. Over time, plaque hardens and narrows your arteries. What is the MOST IMMEDIATE result of atherosclerosis listed here? A) stroke B) heart disease C) constricted blood flow D) peripheral artery disease
Answer:
C) Constricted Blood Flow
Explanation:
Atherosclerosis means when your arteries narrow due to plague and build up. The immediate effect of atherosclerosis would be smaller and smaller amounts of blood passing through your arteries.
The most immediate result of atherosclerosis listed in the given information is C) constricted blood flow.
What is atherosclerosis?
Atherosclerosis is a common and potentially serious medical condition characterized by the buildup of plaque in the arteries. It is considered a type of arteriosclerosis, which refers to the hardening and narrowing of the arteries. Atherosclerosis specifically involves the accumulation of fatty substances, cholesterol, cellular waste products, calcium, and other substances in the inner lining of the arterial walls.
Over time, this plaque buildup can cause the arteries to become narrower, reducing blood flow to vital organs and tissues. It can affect various arteries throughout the body, including those supplying the heart, brain, legs, and other organs. The narrowed arteries may limit the delivery of oxygen and nutrients to these areas, potentially leading to various complications.
Atherosclerosis is a progressive disease that often develops over many years or decades. Factors such as smoking, high blood pressure, high cholesterol levels, diabetes, obesity, and a sedentary lifestyle can contribute to its development. Additionally, genetics and family history may play a role in increasing the risk of developing atherosclerosis.
If left untreated, atherosclerosis can lead to serious health problems, including coronary artery disease, angina, heart attack, stroke, peripheral artery disease, and even death. Management and prevention strategies typically involve lifestyle modifications, such as adopting a healthy diet, engaging in regular exercise, quitting smoking, managing blood pressure and cholesterol levels, and taking medications as prescribed by healthcare professionals.

Certain meteorites have been examined and found to carry samples of which molecules? Select all that apply. lipids nucleotides polypeptides amino acids monosaccharides
The correct answer as to which molecules some examined meteorites contain would be lipids, nucleotides, amino acids, and monosaccharides.
Meteorites are considered to be pieces of rocks or metals that fall into the earth from outer space. These rocks/metals have been extensively studied/analyzed by some researchers, especially those seeking to prove/disprove the Panspermia theory that life originates from other planets.
Several studies conducted found compounds such as lipids, DNA, RNA, and amino acids. There has been no evidence for monosaccharides for a long time until 2019 when an international team discovered sugars such as xylose and arabinose in certain meteorites. No polypeptide has been discovered in meteorites, but its precursor, amino acids, have been discovered.Therefore, the correct answer to the molecules that have been found in some meteorites would be lipids, nucleotides, amino acids, and monosaccharides.

A mint plant grows many horizontal branches along the ground from which new plants can arise. How can this be harmful to the growing plants?
Answer:
The aromatic aroma of mint isn’t as pleasing to many crop pests, so planting crops next to mint can deter these plant nemeses.
Explanation:
Mint can suffer from several plant diseases such as verticillium wilt, mint rust, mint anthracnose. If these strike, the best thing to do is get rid of your mint plants and get new, healthy ones. Just don't place them in the same spot or potting soil because that increases the chances that the disease will spread to the replacement plants as well. In Other Words, If you're feeling kind, you can call mint plants aggressive. If you don't like thugs taking over your garden, you will consider mint invasive. Because it grows by underground root runners, mint spreads easily and quickly. To contain it, grow mint in a 12- to 16-inch-wide pot so it can't ramble through your landscape.
