What is DNA?
DNA is defined as deoxyribonucleic acid and it is a polymer made up of two polynucleotide chains that arranged in helical structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.There are four nitrogen bases of DNA nucleotides are such as adenine, thymine, guanine and cytosine.
Friedrich miescher discovered DNA in the year of 1860.The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA. The shape of DNA is double helical structure. Siblings share only about 50% of same DNA due to the reason of recombination. The life span of DNA is 521 years.
Therefore,In the 'Hershey Chase Experiment' DNA macromolecule did the bacteriophage inject into the bacterium. Thus, option A is correct.

Explain how the hydrogen ion concentration gradient is generated and how it is used to make ATP
Answer:-
ATP Synthase: ATP synthase is a complex, molecular machine that uses a proton (H+) gradient to form ATP from ADP and inorganic phosphate (Pi). Chemiosmosis is used to generate 90 percent of the ATP made during aerobic glucose catabolism. The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation.
Explanation:
Humans sweat, which is triggered by high body temperatures after exercise or hot days in order to
Answer:
Cool the body down by evaporation
Explanation:
Sweat helps cool you down by releasing moisture onto your skin. When this moisture evaporates, releasing heat energy from the skin.
This happens most effectively in dry environments because evaporation happens more efficiently.
Answer:
maintain homeostasis
Explanation:
To maintain homeostasis, animals may sweat in order to release heat from the body.

Which statement best describes the movement of water into or out of a plant during photosynthesis?
A. It is given off into the soil.
B. It is taken in from the air.
C. It is made in the plant.
D. It is taken in from the soil.
Answer:
D
Explanation:
One reactant of photosynthesis is water, meaning it is needed to start the process. So, it must be taken in. It is more logical for water to be taken in from the soil since we water plants' roots, so it is D.
The statement 'it is taken in from the soil' BEST describes the movement of water into or out of a plant during photosynthesis (Option D).
Photosynthesis refers to a series of metabolic reactions by which plant cells use the light energy from the sun, carbon dioxide and water to produce simple sugars (e.g., glucose) and oxygen.In consequence, during photosynthesis, water is a reactant taken from the soil.The photosynthetic reactions involve the oxidation of water (these molecules lose electrons) and the reduction of carbon dioxide (these molecules gain electrons).In conclusion, the statement 'it is taken in from the soil' BEST describes the movement of water into or out of a plant during photosynthesis (Option D).

How do decomposition and synthesis reactions work
to serve the needs of individual cells of your body?
Answer:
Because those chemical reactions help the cell to dispose useless substance after they are used and synthetize substance they need or the body needs through them.
Explanation:
Hello.
In this case, since the overall processes inside the cell are constantly producing and getting rid of several substances such as nutrients, proteins, lipids and other, we can say that decomposition reactions serve as a mechanism that the cell uses in order to obtain energy or dispose a substance that is no longer important for it. Moreover, since the cell is the fundamental part wherein the most of the useful substances the body needs are synthetized, we can infer that synthesis reactions must occur in order to allow the body to perform lots of functions, for instance, proteins associated to the hair or nails growing are synthetized inside the cell via the protein synthesis mechanism.

Which base pairs with cytosine (C) in RNA?
Answer:
guanine
Explanation:
The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn't contain thymine bases, replacing them with uracil bases (U), which pair to adenine1.
The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

NEED HELP ASAP!!!!!!!!!!!!!! Place these organisms (I have used the scientific names) in order from the least to most number of cells: Sorex minutus, Homo sapiens, Bacillus anthracis, Sequoia sempervirens. Look up these organisms' names if you don't know what they are.
Answer:
Bacillus anthracis
Sorex minutus
Homo sapiens
Sequoia sempervirens
Explanation:
Cells of different organisms are usually around the same size - so the larger the organism, the more cells.
Bacillus anthracis is a single celled bacteria, so it has the least amount of cells - one.Sorex minutus is a small shrew, so has less cells than a human or giant tree.Homo sapiens are humans - which have more cells than a small shrew.Sequoia sempervirens are huge trees, and likely havethe most cells.in what part of the day do plants produce more carbon dioxide than oxygen

How can poor nutrition affect individual cell functions?
Answer:
Nutritional imbalance is a major challenge for living organisms to achieve systemic homeostasis and maintain normal physiology. Mammals have developed processes to control systemic nutrient utilization and storage. For example, excess nutrients are converted and stored in adipose tissue, liver, and muscle during times when nutrients are abundant. By contrast, stored nutrients are metabolized to provide energy and building blocks to maintain vital physiological processes when nutrient availability is low.
From these processes, adipose tissue volume changes in response to under- or overnutrition. This change in adipose tissue volume, in turn, influences the secretion of hormones and cytokines from adipose tissue (adipocytokines). Many of these adipocytokines have important immune signaling functions which can influence immune cell biology and alter the immune response.
At the end of this phase, two new daughter cells that are exact replicas of the beginning cell will be completed.
A. metaphase
B. prophase
C. telophase
