Explanation:
ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.
The energy releasing equation, also called enthalpy is calculated using the formula: ΔH = Hfinal - Hinitial
What is enthalpy?Enthalpy refers to the heat content of a system combining the energy of the system with the product of its pressure and volume. When a chemical reaction or physical process occurs energy is emitted in the form of heat.
The equation used to determine the amount of heat released by a system during a reaction or physical process is known as the energy release equation.

I'm basically confused about the directions of this slide. Can someone help me?
If I am understanding correctly, the first thing they are asking you to do is match nitrogen bases.
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Then, whichever are the double strands, cut them out and put them into you notebook. (I am not sure where the notebook is, but I am assuming you know)
Then in the speech bubble next to the picture of Chargaff- talk about his rule.
What does the rule mean?
What does the rule explain?
How is the rule demonstrated?
Lastly, finding percents. What percent of the pairs has Adenine in them?
For example:
If I look at this pairing below
A →T
T→ A
G →C
C→ G
50% of the pairs include Adenine.
Hope I helped! Comment if you have questions about my answer :)
Answer:
If the sequence of nitrogenous bases of a DNA strand is ATCTAGGCCG, the complementary strand would be TAGATCCGGC, with a percentage of guanine 30%, cytosine 30%, adenine 20% and thymine 20%, according to Chargaff's rule.
Explanation:
DNA is made up of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one strand are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=T Guanine is complemented with Cytosine G≡CThe image shows a DNA chain whose chain is complementary:
DNA Strand given Complementary Strand
Adenine Thymine
Thymine Adenine
Cytosine Guanine
Thymine Adenine
Adenine Thymine
Guanine Cytosine
Guanine Cytosine
Cytosine Guanine
Cytosine Guanine
Guanine Cytosine
Therefore, in a DNA molecule there is as much adenine as thymine, and an equal amount of cytosine and guanine. In this example there are 4 molecules of adenine, 4 molecules of thymine, 6 guanines and 6 cytosines.
The proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff was able to establish that in a DNA molecule the ratio of purine:pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, according to the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
Guanine 30%
Cytosine 30%
Adenine 20%
Thymine 20%
Total ..... 100%

A pulmonary (lung) artery obstruction is referred to as an acute pulmonary embolism or embolus.
What can be diagnosis of acute pulmonary embolism?Acute pulmonary embolism (PE) causes 50,000 to 200,000 deaths per year and is a common cause of death. After coronary artery disease and stroke, it is the third most prevalent cause of mortality among cardiovascular diseases. The development of multi-detector computed tomographic pulmonary angiography (CTPA) has increased the rate of diagnosis of PE by enabling improved assessment of PE regarding imaging of the peripheral pulmonary arteries. As a result, more instances of accidental PE and isolated subsegmental PE (SSPE), two types of peripheral PE, have been discovered. Usually, patients with these two disorders have little to no evidence of the traditional PE symptoms, such as hemoptysis or pleuritic discomfort, abrupt dyspnea, or circulatory collapse.

The energy carrying molecules are made in stroma where the calvin cycle takes place.
What function do ATP and NADPH serve in light-independent reactions?In photosynthesis, light energy is utilized to cause the photosystem I molecule to make ATP by transferring electrons from chlorophyll to nicotinamide adenine dinucleotide phosphate (NADPH) (Figure 5). In the light-independent processes of photosynthesis, this metabolic energy is utilized to fixation CO2 (Calvin cycle).

A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.
B)There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.
C)There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.
D)There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.

It is believed that weed killers like 2,4-D and 2,4,5-T may
work by stimulating cell division. Why would the stimulation
of cell division make these chemicals effective weed killers?
Herbicides are a broad category of pesticides that are used to get rid of undesirable plants like weeds and grasses that hinder the development and productivity of desired agricultural crops. Both 2,4-D and 2,4,5T are also known as 2,4-Dichlorophenoxyacetic acid and
Herbicides like 2,4-D and 2,4,5-T are also referred to as auxin-type herbicides or plant growth regulators. Auxins are hormones that affect cell division and elongation in order to control cell growth.Auxins are required by plant cells in the proper concentration for growth and development. If auxin levels are too low, plant growth is not promoted at all, and if levels are too high, plant growth is excessively stimulated. Most grasses are not killed by 2,4-D and 2,4,5 T, but broadleaf weeds are. It moves to the plant's meristems after being absorbed through the leaves. These herbicides affect the tissues' cells, causing them to continually divide and proliferate. The plant finally dies as a result of this unchecked, unsustainable growth, which also causes stem curling and withering of the leaves.Thus, by promoting cell division, these compounds act as herbicides.
