During photosynthesis, molecules inside chloroplasts in plant cells absorb energy from the Sun. Which statement best describes how photosynthesis follows the law of conservation of energy?
a. Light energy from the Sun is converted into kinetic energy in plant cells.
b. Chemical energy from the Sun is converted into light energy in plant cells.
c. Light energy from the Sun is converted into chemical energy in plant cells.
d. Chemical energy from the Sun is converted into thermal energy in plant cells.
During photosynthesis, the law of conservation of energy is followed when light energy from the sun is converted into chemical energy in plant cells. So the correct option is C.
What is photosynthesis?During the process of photosynthesis, the chlorophyll present in the chloroplasts of plant cells performs the function of trapping sunlight.
The sunlight trapped by the chloroplasts represents light energy. In plant cells, the light energy is converted to chemical energy. The chlorophyll molecule is photochemically excited and loses an electron. Thus it performs an oxidation reaction.
The chemical energy causes hydrolysis of water. The water molecule produces oxygen and hydrogen molecules. The oxygen molecule is released as a product of the photosynthetic reaction.
The hydrogen molecule is used for the reduction of carbon dioxide to form glucose which is a six-sugar molecule.
Therefore the correct option is C.

Explanation: Hope this help :)
Hello?? Can anyone help me??! PLEASE
Answer:
The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.
I don't think I put enough detail into that explanation but I hope this helps your problem.

Assume that a DNA double helix contains 100 base pairs (one pair is A-T or C-G) and there are 45 cytosines.
a. How many guanines are there?
b. How many adenines are there?
Cytosine(C) binds with Guanine(C)
Adenine(A) binds with Thymine(T)
a.From here we can deduct that there are the same number of nucleotides of guanine that as cytosine=>G=45 base pairs
b.2A=100-G-C
2A=100-90 2A=10 A=5 base pairs

A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.
What is cellular respiration?Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.
Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.
Disorders that interfere with cellular respiration typically affect one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.
Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

Compare and contrast lactic acid fermentation and alcoholic fermentation. Include examples of organisms that use each type of fermentation.
Answer:
Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.
Explanation:
The comparison between lactic acid fermentation and alcoholic fermentation-
1. Lactic Acid Fermentation:
pyruvate changes to lactic acidused by muscle2. Alcoholic fermentation:
pyruvate changes to alcohol and carbon dioxideused in bread by yeast, wine, and biofuelsLactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into ATP which is cellular energy and the metabolite lactate, which is the lactic acid in solution.
Alcoholic fermentation is a biological process by which sugar is converted into alcohol and carbon dioxide with heat.both happen under anaerobic conditions and produce a little amount of ATP.Alcoholic fermentation gives CO2 while lactic acid does not.1. Lactic Acid Fermentation:

Which best explains the genetic similarities between species? A. More closely related species will have identical dna B. More closely related species will have fewer dna similarities C. More closely related species will have more similarities in dna D. There is no link between the relationships of species and their dna
Answer:
C
Explanation:
The correct answer would be that more closely related species will have more similarities in DNA.
The DNA stores the genetic information of organisms and contains a set of instructions that defines how organisms look. It is usually used to delimit species with closely related species of organisms having similar DNA. The more related species are, the more similar their DNA would be and vice versa because the similarity in the DNA of organisms is often used as an indication of descending from a common ancestor.
The correct option is, therefore, C.
Genes are the hereditary unit of life, which carries the information from parent to daughter cells. The organisms belonging to the same species will have the same genetic sequence.
The correct answer is:
Option C. More closely related species will have more similarities in DNA
The DNA stores the genetic information of the organisms and codes for the traits of the organism.
The genes delimit the species' relativity of the organisms. The species that are closely related will have more similarities in the genetic sequence.
The similarity of the genes or DNA is often used as an indication of descending of species from a common ancestor.
Therefore, option C is correct.
