b. They are substrates for aerobic metabolism and if increased in the blood show that the cardiac muscle is not functioning normally.
c. These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.
d. They are by-products of anaerobic metabolism (glycolysis) and if increased indicate that the heart is not receiving oxygen.
Answer:
c.These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.
Explanation:
Answer: A
Explanation:
A agrees with the original statement, so if Fred cannot swim it must be absolutely true that he is not one of Kay's brothers. Dave being able to swim would support that he is one of Kay's brothers, not refute it. Walt being able to swim does not automatically mean he is related to Kay, so that is not necessarily true. Pete being unable to swim also refutes the original statement. Mark not being Kay's brother has no correlation to his swimming ability.
DNA is considered a good storage house for storing information due to the presence of nucleotide which helps in providing each cell a piece of information.
Further Explanation:
Genes are present in DNA and defined as the linear sequence of the nucleotides that are responsible for encoding a protein that has a particular function. The alleles are defined as the variant type of the gene. DNA is mainly made up of the nucleotides and also contains genetic information in the genes. Phosphate group, deoxyribose, and nitrogenous base altogether make up a nucleotide. DNA is mainly composed of four distinct types of nitrogenous base:
The arrangement of nucleotides in the DNA is mainly required for the structural and functional activities of an organism. That’s why DNA can be considered as a storage house for all the hereditary information of an organism. The sequence of nucleotides gives a specific function to the cell. Each nucleotide present in the DNA is specific to their functioning.

Keywords:
DNA, cytosine, guanine, thymine, adenine, hereditary information, arrangement, chromosome, gene, function, base, sequence, nucleotide, organism.
Its bases can be joined together in any order, like the letters of the alphabet can be strung to form different words. Option A
Due to the flexibility with which its bases—adenine, thymine, guanine, and cytosine—can be organized and linked along the DNA strand, DNA (deoxyribonucleic acid) is a good molecule for storing information. Similar to how the alphabet's letters may be put together to make various words, phrases, and paragraphs, this allows for the encoding of a wide variety of information.
DNA carries the genetic instructions for the growth, operation, and reproduction of living things in a precise order of nucleotide bases. Each base sequence holds a distinct piece of knowledge, such as the guidelines for constructing proteins or the management of different cellular operations.

A controlled experiment is crucial for isolating the effects of a single variable, making it easier to interpret the results.
All variables save the one being researched (the independent variable) are held constant in a controlled experiment. This enables researchers to draw more precise conclusions regarding the link between independent and dependent variables.
It would be difficult to identify whether the outcomes were attributable to the variable being examined or some other factor without control groups and uniform circumstances. Controlled experiments improve the reliability and validity of data obtained, laying the groundwork for scientific ideas and applications.

B. recognize infected body cells.
C. discover antigens in body fluids.
D. are made in the red bone marrow.
The correct answer is (c) discover antigens in body fluids.
B lymphocytes act as antigen presenting cells that recognizes and displays the antigen to the white blood cells. These cells process the antigens that are present in body fluids. Professional antigen presenting cells includes B-lymphocytes, macrophages, dendritic cells, etc.
