Genes code for specifically structured
sugars.
acids.
lipids.
proteins.

Answers

Proteins is the answer

Genes code for specifically structured proteins. The majority of genes have the necessary instructions to produce the useful molecules known as proteins, hence option D is correct.

The segment of DNA needed to make one protein is known as a gene, because they code for proteins consisting of hundreds or thousands of amino acids, genes often have hundreds or thousands of base pairs.

The ribosome, a specialized complex that "reads" the sequence of mRNA nucleotides, interacts with the messenger RNA (mRNA). A codon is a group of three nucleotides that typically codes for one specific amino acid.

Without the microscope, we would not know about the existence of cells or how plants breathe or how rocks change over time. Cell theory was discovered by Robert Hooke in 1665 with the help of a microscope.

Exercise cannot be sustained when anaerobic respiration takes place in muscle cells.
Explain why.​

Answers

False. Exercise can be sustained when anaerobic respiration takes place in muscle cells, but in addition to aerobic respiration.

Exercise and anaerobic respiration

Anaerobic respiration, also known as fermentation, can occur in muscle cells when there is not enough oxygen available to support aerobic respiration.

This process generates ATP by breaking down glucose without using oxygen. However, it is much less efficient than aerobic respiration and produces lactic acid as a byproduct.

Thus, in addition to aerobic respiration, anaerobic respiration in muscle cells can help sustain exercise.
