B and D
Explanation:
I did that question
Answer:
The correct answer is B
Explanation:
describe the relationship between genotypes and phenotypes
Answer:
Genotype is the potential, it is the set of genes.
Phenotype is the expression of those genes, showing the dominant/ activated gene.
For example, my mother and members of her family are short with hazel eyes and dark hair.
My dad and his family are tall, with brown eyes and dark hair.
I will have genes for height that vary- short or tall. I will have genes for eyes hazel or brown.
I will have genes for hair- dark.
You don’t know, based on what i’ve told you, what my height or eye colour is. That’s my genotype.
I am tall, with hazel eyes and dark hair. That’s my phenotype.
This is really over simplified, but it should help you understand.
Genotype is the blueprint/ building plans. Phenotype is the building.

Which of the following molecules is an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms?
a.) Saturated fatty acids
b.) Unsaturated fatty acids
c.) Fructose
d.) Glucose
Answer:
B
Explanation:
Unsaturated fatty acids have kinks in the fatty acid chains. Every double bond is a kink.
Unsaturated fatty acids are an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms.
What do you mean by Molecules?Molecules may be defined as one or more groups of atoms held together by various chemical bonds.
On the basis of the number of bonds, fatty acids are classified into two categories, i.e. Saturated and unsaturated fatty acids.
Saturated fatty acids consist of only a single bond with long carbon chains with terminal carboxylic acid, while unsaturated fatty acids consist of double or triple bonds with long carbon chains with a terminal carboxylic acid.
Therefore, unsaturated fatty acids are an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms.

Which of the following statements is true?
Groundwater is not part of the water cycle.
Most of the earths water is freshwater.
Thermal pollution is the main disadvantage of hydroelectric power.
Refining oil pollutes the air with nitrogen dioxide.
Answer:
Im pretty sure that "Refining oil pollutes the air with nitrogen dioxide" is a true statement.
Explanation:
well,,, all the others are false because: groundwater is definitly part of the water cycle, most of earth's water is NOT fresh bc only 2% of earth's water is fresh, and hydroelectric power would contribute more to water pollution than to thermal pollution-

that directs the ribosome to build certain--------------------
as needed by specific cells or situations.
Answer:
DNA contains genes that can be read to create messenger RNA that directs the ribosome to build certain proteins as needed by specific cells or situations.
Explanation:
DNA is a nucleic acid that contains in its structure a specific sequence of nucleotides, whose quantity and order determine the genetic information of an individual. A chromosome consists of a DNA molecule, and each fragment of this molecule constitutes genes with specific instructions for determining structural and functional characteristics.
Transcription is the process by which DNA can be read and transcribed into messenger RNA (mRNA), a molecule that carries the genetic code to the ribosomes for protein synthesis, in a process called translation.
When a cell needs to synthesize a specific protein, transcription and translation mechanisms occur so that the protein can be synthesized.
Which of the following types of the cell transport moves from low to high concentration and requires energy
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Explanation:
This should be correct.

ATP and ADP both play a role in cellular reactions involving energy. How are these two molecules related?
A Adding a phosphate group to ADP produces ATP and releases energy.
B. ATP breaks down to produce ADP and a phosphate group, releasing energy
C. ADP breaks down to produce ATP and a phosphate group, releasing energy
D. Adding a phosphate group to ATP produces ADP and releases
Answer:
A
Explanation:
You can see it in the picture:
The molecules of ATP and ADP are related to one another in the sense that the breaking down of ATP produces ADP and a phosphate group, releasing energy. Thus, the correct option for this question is B.
What is the process of adding a phosphate group called?The process of adding a phosphate group to any organic compound such as glucose, ADP, etc. is known as phosphorylation. This process increases the catalytic activity and downstream process of cell signaling.
Eliminating one phosphate from ATP in order to convert it into ADP liberates energy. This is because breaking one phosphoanhydride bond liberates approximately 7.3kcal/mol of energy. While the addition of a phosphate group to ADP in order to produce ATP requires some utilization of energy.
Therefore, ATP breaks down to produce ADP and a phosphate group, releasing energy is a statement that represents a relation between ATP and ADP. Thus, the correct option for this question is B.
