Sari and Jon disagree over who needs more calories (proportionately) per day to survive a three-month-old baby or a
grown adult San argues that a grown adult is bigger and needs more calories per pound of body weight Jon believes
the baby would require more calories per pound of body weight
he is most likely conect and why?
San, because it takes more energy to move the larger muscles that adults have, so they need more calories
Jon, because babies grow at a much berate than adults and require more cabries to support this growth
Jah, because babies are more active than grown adults and need more energy from calories
San because adults have more to do during the day and need more calories to sustain their activities
Answers
San is correct , because it takes more energy to move the larger muscles that adults and is denoted as option A.
What is Calorie?This is referred to as a unit of energy in food substances such as carbohydrates, fats etc.
Adults have larger muscles composed of bigger tissues which requires more energy for their functioning in our daily activities which is why San was correct.

A plant is homozygous for the production of yellow seeds (YY) and homozygous for wrinkled seeds (r). What possible gametes will this plant produce?
OA. Yr only
OB. YY and rr only
OC. Y, y, and r only
OD. YR, Yr, yR, and yr
Answers
A plant is homozygous for the production of yellow seeds (YY) and homozygous for wrinkled seeds, possible gametes will this plant produce (r) Y, y, and r only. Thus, option "C" is correct.
How, explain your answer?The plant is heterozygous (Yy) for the color of seed and homozygous (rr) for the shape of the seed.
For the color of the seed, there are two alleles that will take part in gametes formation are (Y) n (y) while for the shape of seed is have only two recessive alleles (r).
So, by the assortment of (Y) n (r) the first gamete will be (Yr) and an assortment of (y) n (r) second gamete will be (yr).
Thus, the correct answer is option C. Yr and yr only.

Because one of the two strands of a replicated DNA molecule is newly synthesized and the other is the original template, DNA replication is said to be a semi-conservative process.
What is DNA replication?DNA replication may be defined as the biological process that involves duplicating a DNA molecule comparable to the construction of two DNA molecules.
DNA replication is proceeded by the semiconservative model, which means that the parental double helix is half conserved, and each parental single strand remains intact.

Answers
(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.
How temperature effects the rate of a chemical reaction
Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.

e) The allele for small size is recessive, and the allele for normal size is dominant. The frequency for the normal-size allele is 0.72. What percentage of the rats are normal sized? (3 points)
Answers
Answer:
51.84%
Explanation:
p² + 2pq + q² = 1 and p + q = 1
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
p = 0.72 => p² = 0.72² = 0.5184
=> Percentage of the rats are normal sized: 51.84%

Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen).
During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise. As byproducts, carbon dioxide and water are produced.
What are the three stages of cellular respiration?The Krebs cycle, oxidative phosphorylation, and glycolysis—an anaerobic process—are the three phases of aerobic cellular respiration.
All forms of cellular respiration begin with glycolysis, which is anaerobic and oxygen-free. The pathway will go on to the Krebs cycle and oxidative phosphorylation if oxygen is present. However, some species may engage in fermentation to continuously manufacture ATP in the absence of oxygen.
Total amount of ATP molecules generated during aerobic respiration from a single glucose molecule.
During glycolysis:
As 2ATP
From 2NADH 5ATP (oxidation phosphorylation)
In pyruvate oxidation;
From 2NADH 5ATP (oxidative phosphorylation)
