Explanation:
Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?
The parts of the molecule whose bond must be broken to form an ADP molecule would be between C and D. Thus, option A would be correct.
The image is an illustration of the structure of ATP, Adenosine Triphosphate. The hydrolysis of the terminal phosphoanhydridic bond in ATP yields energy for metabolic reactions in biological systems and ADP (Adenosine Diphosphate) is formed as a result.
In this case, the terminal phosphoanhydridic is D. Thus, the bond between D and C must be broken for ADP to result.

What does the SAGE instrument measure?
Answer:
The SAGE instrument measures the amount of ozone and other trace gases that are in the atmosphere by measuring the amount of sunlight that comes through the atmosphere at different altitudes.
Explanation:
The structure labeled "A" open and close the sites where the gases, carbon dioxide and oxygen, are exchanged during photosynthesis. What is the structure labeled A?
The structure A in the question seems missing but the given answer is based on the description given in the question.
Answer:
The gaseous exchange of carbon dioxide(CO2) and oxygen(O2) occurs through small, regulated openings called stomata during photosynthesis.
Therefore the Structure A is Stomata

In your own words describe how genetic diversity is increased through the processes of crossing over, independent assortment, and random sexual reproduction.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made
Answer:
D)NADPH is made
A)ATP is used
Explanation:
Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]
The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:
Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.
First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).
Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

Explanation:
Cells with 46 chromosomes are called _______ cells because they have two sets each.
Answer:
Cells with 46 chromosomes are called diploids cells because they have two sets each.
Explanation:
In the human being, somatic cells contain 46 chromosomes (23 pairs), representing the complete chromosomal charge, so they are called diploid cells.
Ploidy is based on the total number of chromosomes contained in a cell:
If the cell has the full charge of chromosomes —like somatic cells— is called diploid, and its formula is 2n. Cells with half the chromosome charge are called haploid, their formula is n, and corresponds to sex cells or gametes.Two haploid cells can unite during fertilization, to give rise to a diploid cell, the gamete, which represents the basis of sexual reproduction. In humans, Cells with 46 chromosomes are called diploids cells because they have two sets of chromosomes each.
