The process of diffusion occurs when
A. all molecular movement stops.
B. molecules move from areas of lesser concentration to areas of greater
concentration
C. sugar molecules move into a cell.
D. molecules move from areas of greater concentration to areas of lesser
concentration.
Answer:
d
Explanation:
The process of diffusion occurs when molecules move from areas of greater concentration to areas of lesser concentration. The correct option is D.
What is diffusion?The movement of essential, small molecules across the cell membrane as well as the movement of materials within cells both depend on the process of diffusion.
The exchange of gases in the lungs and gills is regulated by this process. As a byproduct of biological metabolism, carbon dioxide is released by all cells.
For example, when you pour a red color drop into the water, slowly the color molecules are evenly distributed in the whole water. It does not need any energy because it works according to the concentration gradient.
Thus, the correct option is D. molecules move from areas of greater concentration to areas of lesser concentration.

Pea plants can have yellow seeds or green seeds Which conclusion about the meaning of Y is correct if the allele
combination Yy is for yellow seeds?
O yellow and dominant
O green and recessive
O yellow and recessive
Ogreen and dominant
Save and Exit

Submit
Mark this and retum
Answer:
yellow and dominant
Explanation:
Gregor Mendel has stated that a gene comes with two alleles. According to his law of dominance, one of the alleles called DOMINANT allele is capable of masking the phenotypic expression of another allele called RECESSIVE allele.
In this question involving a seed color gene, which has two alleles Y and y. Y, which represents the dominant allele codes for the YELLOW trait while y, which represents the recessive allele codes for the GREEN trait. Therefore, a plant with Yy will have YELLOW SEEDS because the dominant allele (Y) is present.

1)What is it about the structure of ATP that contributes to its ability to act as an energy currency?
2)When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
Answer/Exlanation:
1) ATP (adenosine triphosphate) can be hydrolyzed such that it loses a phosphate group to form ADP (adenosine diphodphate). This is called ATP hydrolysis. This property allows ATP to act as energy currency because ATP hydrolysis releases the energy stored in the high energy phosphate bond.
2) Transporting molecules against their concentration gradient requires energy. When ATP loses its phosphate group, it can phosphorylate another molecule. This converts the molecule into its active state, giving that molecule the energy to pass through against the concentration gradient.
1) The ability of the ATP compound structure to act as an energy currency has been explained in the answers.
2) The method used by ATP to allow protein transport molecules against their concentration gradient has been explained below.
1) ATP is an acronym that stands for Adenosine triphosphate. This compound called ATP is divided into three phosphate groups with phosphate bonds that possess very high energy. Now, when water is added to ATP, the phosphate bonds that possess high energy will be broken down thereby releasing energy and producing adenosine diphosphate (ADP).
2) We saw above that when ATP undergoes hydrolysis, the phosphate bonds are broken down to form ADP and releases energy. However, it can undergo further phosphorylation to form another molecule which becomes energized when it goes to a higher energy state.
Now, In this higher energy state it gets to, it will be observed that the protein will possess enough energy to transfer molecules against a concentration gradient that requires energy.

Click on "Embankment dam at a gold mine." Of the two opinions to consider in this case, which one presents a stronger argument? How does that help you make your final decision as the consulting dam engineer? What was your decision for this dam, as the consultant? How can you accomplish this and still stay within your budget? (Site 1)
Answer: The strongest argument is the one that refers to security of people. This helps me to make a final decision, to ensure that there will be no accidents and guarantee that the mine will be used to generate moeny. So my decision is to repair it but choose to repair only the most urgent parts, to still stay within the budget.
Explanation:
A gold mine is a place where gold is extracted from the ground. Because of its value, the extraction of gold generates economic and social benefits all over the world, which has made this activity one of the most important in the world. There are also many ways of extracting this mineral.
The best argument will be the one that indicates the greatest concern for the safety of the citizens of that city or town. If there is a dam, it should be repaired in the best possible way. This will ensure the safety of the town and guarantee that the mine continues to be used, to generate economic benefits. Then, if the gold mine continues to be used even if it is not productive as it was, it must be repaired. However, in order not to make large expenditures and have a low budget for repair, I can choose to repair only the most urgent or necessary part.
So, the strongest argument is the one that refers to security of people. This helps me to make a final decision, to ensure that there will be no accidents and guarantee that the mine will be used to generate money. So my decision is to repair it but choose to repair only the most urgent parts, to still stay within the budget.

assignment is due at 6:30 its 6:09
Answer:
1 : the living together in more or less intimate association or close union of two dissimilar organisms (as in parasitism or commensalism) especially : mutualism. 2 : a cooperative relationship (as between two persons or groups) the symbiosis
Symbiosis is the type of relationship or interaction between two different living organisms that share a similar kind of habitat. This is of three types including mutualism, commensalism, and parasitism.
What is Symbiosis?Symbiosis can be defined as a type of relationship or interaction between two different living organisms which share a similar habitat. There are three different types of behaviors that were observed in symbiotic relationships, namely mutualism, commensalism, and parasitism.
In this type of interaction, the organisms live in a close physical association with each other. In the case of symbiosis, both the organisms are benefitted from the interaction. This type of interaction provides an advantage to both the organisms. The common example of symbiosis is the Rhizobium bacterium species and the leguminous plants.

Why flower produces only a small amount of nectar (food for insects) at a time
Answer:
Nectaries are usually located at the base of the flower stamens, which draw animal visitors into contact with the pollen to be transferred. Most flowers secrete only relatively small amounts of nectar, which encourages cross-pollination, since animals must visit several flowers in order to receive a full meal.

Which of the following is released from ATP and therefore provides “energy”?
A) water
B) Pi
C) glucose
D) ADP and Pi
E) ADP only
Pi or inorganic phosphate is released from ATP and therefore provides energy.
What is ATP?It is the energy-carrying molecule found in the cells of all the living things. It is a nucleotide, which comprises three main parts, that is,
The nitrogenous baseAdenineRibose sugarA chain of three phosphate groups combined to riboseThe tail of phosphate is the actual source of energy, which is tapped by the cell. The accessible energy is present within the bonds between the phosphates and is discharged when the bonds are dissociated. It takes place via the supplementation of a water molecule, the process known as hydrolysis.
Generally, only the outer phosphate is withdrawn from the ATP to produce energy, when this takes place ATP get transformed to ADP or adenosine diphosphate.
Thus, the correct answer is option B, that is, Pi.

What characteristic of viruses distinguishes them from cells?
Answer: Viruses, although not living things, do show some characteristics that they are living. Because they can't reproduce by themselves (without a host), viruses are not considered living. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA.
They are acellular, that is, they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.
