Why do different individuals of the same species have different traits?
OA. Individuals have differences in their genes that result in protein variations.
OB. Individuals have proteins that produce genes with completely different functions from other individuals.
OC. Individuals have different proteins that cause variations among their genes.
OD. Individuals have different genes that produce proteins with completely different functions from other individuals.
answer : a
explanation : a species shares ALMOST all of the DNA with each other with just small differences
Different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.
Why do individuals of different species exhibit different characteristics?
The species is a group of individuals that can reproduce among themselves and can produce fertile offspring. Individuals of a species have genetic variation among them as they are formed by the process of meiosis.
In meiosis, genes cross over and recombination takes place, resulting in the formation of offspring that show some variation from their parents. These characters or traits are encoded in the gene. When these are expressed in the process of translation, the variation is seen.
This genetic variation doesn't make them reproductively isolated. Example: In humans, there are variations based upon the skin color, face size, height, etc. The variation is seen in genes among individuals but not genes are different.
Hence, different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.

Which is not true about mitosis A. The chromosomes in the daughter cells are half the number from the parent cell B. The chromosomes in the daughter cells are the same number as the parent cell C. Each nuclei is identical to the parent nucleus D. The four main stages of mitosis are prophase, metaphase, anaphase, and telophase
The chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).
What is Mitosis?Mitosis is defined as the part of the cell cycle in which the duplicated chromosomes are divided into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes remains the same. Hence, it is also known as Equilateral Partition.
The phases involved in the mitosis are :-
ProphasePrometaphaseMetaphaseAnaphaseTelophase.Mitosis occurs in somatic cells which occurs in all types of cells that are not involved in the production of gametes. Each mitotic division contains one copy of each chromosome, thus a complete set of chromosomes is found in the nucleus of each new cell.
Thus, the chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).

Why are cells are able to harvest about 34% of the available stored potential energy in a glucose molecule? What happens to the other 66%?
Answer:
Why are cells are able to harvest about 34% of the available stored potential energy in a glucose molecule is because of the process of cellular respiration. And what happens to the other 66% is that it's used to make water from hydrogen ions and oxygen that converted to heat and used directly for energy to store as fat

Which statement best describes what happens during translation?
Answer:
B
Explanation:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
During translation, the ribosome reads the mRNA and uses the information to assemble a protein.
Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.
Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.
The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.

Which statement best compares the amount of fossil fuels formed each year to the amount used each year? The amount of fossil fuels formed is exactly the same as the amount used. The amount of fossil fuels formed is approximately the same as the amount used. The amount of fossil fuels formed is much less than the amount used. The amount of fossil fuels formed is greater than the amount used.
Answer:
The amount of fossil fuels formed is much less than the amount used.
Explanation:
Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.
One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

If a strand of DNA has 45% A, what percent will be C?
Answer:
55%
Explanation:
Answer:
[tex]\boxed {\boxed {\sf C=5\%}}[/tex]
Explanation:
There is a method to calculating base percentages known as Chargaff's Rule. It states:
[tex]A+T+G+C=100\%[/tex]
We know the DNA has 45% Adenine or A.
Adenine always pairs equally with Thymine. In other words, the percentage of adenine equals the percentage of thymine (45% Thymine or T).
[tex]45\%+45\%+C+G=100\%[/tex]
[tex]90\%+C+G=100\%[/tex]
Subtract 90% from both sides.
[tex]90\%-90\%+C+G=100\%-90\%[/tex]
[tex]C+G=10\%[/tex]
Cytosine(C) and Guanine(G) pair equally and their percentages will be equal. We can divide 10% by 2.
[tex]C+G=10\% /2[/tex]
[tex]C/G=5\%[/tex]
The percentage of Cytosine or C is 5 percent.
