Body cells divide by mitosis, and gametes are formed by meiosis.

A. True
B. False

Answers

Answer 1
Answer: True

This would help!
Answer 2
Answer: When a cell divides by way of meiosis, it produces four cells, called gametes.Gametes are more commonly called sperm in males and eggs in females. Unlike in mitosis, the gametes produced by meiosis are not clones of the original cell, because each gamete has exactly half as many chromosomes as the original cell.

Given the number of oscillations a wave completes in a period of time, you can determine the amplitude. wavelength. frequency. equilibrium.

Answers

The answer is; frequency

One period is the time taken for a particle in a wave to make a complete cycle, for example from one distinct  point in the phase to the exact same point again. The period can be used to infer the frequency of the wave. The shorter the time it takes to complete this cycle, the higher the frequency of the wave. This is given by the following equation;

T = 1/f
I believe it is the frequency, because when a oscillation occurs that is the starting point to determine when another wave is to come.

Which event occurs in photosystem I? A. Water molecules are broken apart B. Light energy excites electrons C. Oxygen is released as waste D. Electrons are transferred to ferredoxin

Answers

I think the correct answer from the choices listed above is option D. The event that happens in photosystem I is that electrons are transferred to ferredoxin. This is a part of photosynthetic light reactions which makes use of light energy to transfer electrons from plastocyanin to ferredoxin.

from the choices listed above is option D.

A biologist collects DNA samples from two sisters. The younger sister has blond hair. The older sister has red hair. The sisters have different traits because their DNA contains different —A---order of nucleotides
B---types of sugar molecules
C---sized phosphate groups
D---types of nitrogenous bases
PLZ ANSWER IF U ARE ONLY SMART AT THIS STUFF

Answers

The sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).

DNA is a double helix composed of two long chains of nucleotides.

In DNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Thymine and Cytosine.

During gene transcription, a fragment of DNA called gene is used as template to create an mRNA, which is in turn used as template to create a protein.

The order of nucleotides in a given gene sequence determines the sequence in mRNA and ultimately also the protein sequence that's synthesized from this sequence.

In conclusion, the sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).

Why can yeast be considered a parasite?

Answers

Yeast are also found on the surface of the skin and in the intestinal tracts of warm-blooded animals, where they may live symbiotically or as parasites. The common "yeast infection" is typically caused by Candida albicans.

If the heart becomes damaged or weakened, how will this affect the body’s systems? A. The muscular system will strengthen the heart. B. Only the nervous system will be unable to function. C. The circulatory system will not function well, which will affect all other body systems. D. Only the circulatory and respiratory systems will be affected.

Answers

If the heart becomes damaged or weakened, then the circulatory system will not function well, which will affect all other body systems (Option C).

  • The heart is a fundamental organ that forms part ofthe circulatory system.

  • This system (circulatory system) consists of blood, blood vessels (i.e., veins, arteries, capillaries), and the heart, which work together to carry out oxygen and nutrients to all body cells.

  • The heart is an organ responsible for pumping blood through these vessels to all cells of the body.

In conclusion, if the heart becomes damaged or weakened, then the circulatory system will not function well, which will affect all other body systems (Option C).
