Explanation:
different types of cells use different amounts of energy
Some cells, such as human nerve and muscle cells contain many more mitochondria than do cells such as skin cells, some cells have more mitochondria than others as they use more energy. Thus option A is correct.
What are the characteristic feature of mitochondria ?
Mitochondria is commonly called as the “Powerhouse of the cell, these are double membrane-bound organelle present in most eukaryotic organisms located in cytoplasm and function as cell's “digestive system.”
They involve in break down of nutrients and generate energy-rich molecules, cellular respiration occur within the mitochondria, was first described by a German pathologist named Richard Altmann in the year 1890.
The mitochondrion is rod-shaped structure found in both plant and animal cell, size ranges from 0.5 to 1.0 micrometre in diameter, consist outer membrane, an inner membrane, and a gel-like matrix.
The outer and inner membrane are composed of proteins and phospholipid layers which is separated by the intermembrane space.

1. Which of the following is an example of a mutation?
ANSWER: a. A red blood cell loses its nucleus
b. A zygote receives two X chromosomes
c. A strand of mRNA is produced from DNA
d. A nucleotide is missing in a replicated DNA
Answer:
A
Explanation:
Quite simple actually. When a blood cell loses its nucleus it has no type of genetic code in order for it to function. With no DNA or Nucleus, the organelles inside the cell serve no purpose. This causes the cell to either swole or shrink. This is a form of mutation. This happens when there is no activity in the cell and it loses its proteins in the cell membrane, which leads the cell to use passive homeostasis more often than active. With no genetic code for it's cell transport, the cell gives out more necessary molecules, or takes in more necessary molecules.
If a nucleotide is missing in a replicated DNA, it would lead to a change in the gene expression which would lead to mutation. The correct answer is option d.
An alteration in the DNA sequence is known as a mutation, which can happen spontaneously or as a result of toxins or radiation. An organism may experience no effect, negative consequences, or positive effects as a result of a mutation.
Option d here refers to a mutation in which a nucleotide is absent from a DNA molecule that has been duplicated. The building components of DNA are called nucleotides, and if one is absent, the genetic code can be changed. This alteration in the DNA sequence may have serious repercussions, including the development of hereditary illnesses or disorders.
Therefore, a nucleotide is missing in a replicated DNA is an example of mutation i.e. Option D.

What are the two main types of cells and where are they found in the human body?
Answer:
They are prokaryotes and eukaryotes and prokaryotes are single celled and eukaryotes are multi celled
Explanation:
Hope that helps! Have a fantastic day!
The two types of cells found in the human body are blood cells and immune cells.
What are cells?Cells are the fundamental foundations of all life. Trillions of cells make up the human body.
They support the body's structure, absorb nutrients from food, repurpose those nutrients into energy, and perform specialized functions.
Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic compounds found in all cells.
A cell is made up of three parts: the cell membrane, the nucleus, and the cytoplasm that lies between the two.
The cytoplasm contains complicated accommodations of fine fibers as well as hundreds or even thousands of tiny but distinct structures known as organelles.
Thus, there can be many cells in a human body, the most important perhaps are blood cells and immune cells.

Answer:
B
Explanation:
Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.
What are genes made up of?Genes are made of DNA and code for proteins.This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.

Which of the following statements about muscles and the muscular
system is true?
O The three types of muscle tissue are skeletal muscle, smooth muscle, and involuntary
muscle.
O Muscles always work independently to move parts of the body.
All muscle action is voluntary, or able to be consciously controlled.
OSmooth muscle moves food through the digestive system.
Smooth muscle moves food to the digestive system, which is the true statement about the muscle and muscular systems. Hence, the fourth option is the correct answer.
What are different types of muscles?In the human body, there are three types of muscles: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle is called voluntary muscle.
Voluntary muscles move in response to commands. Examples are the muscles of the hand and legs. They move when an organism wants to move. Cardiac muscle and smooth muscle are involuntary in nature.
The contraction and relaxation of involuntary muscles don't depend on the individual's wish. Smooth muscles are present in the internal organs such as the intestine, stomach, etc. When food reaches the stomach, the stomach muscle contracts and relaxes to digest the food. The cardiac muscle is present in the heart. It always works.
Hence, option 4 is the correct answer, as smooth muscle moves food through the digestive system.

What's the exact path of a deoxygenated blood cell?
The question:
Trace a deoxygenated Red Blood Cell from your leg muscle on its path to picking up oxygen and then bringing some oxygen to the brain. Continue to trace that same RBC from the brain then to supply the bicep muscle with oxygen.
Answer:
This is the pathway of the RBC from the leg into the brain and then to the bicep muscle.
Explanation:
The RBC in the leg with run up from the axillary vein into the inferior vena cava into the right atria. Then it is pumped into the right ventricle and is pumped into the pulmonary arteries to the lungs. The RBC meets the alveoli in the lungs, through the capillaries, and Type 1 cells help with the gas exchange of Carbon Dioxide and Oxygen into the RBC. The RBC then travels up and to the pulmonary veins into the left atria of the heart. It them gets pumped into the left ventricle where it is pumped up the aortic trunk and travels through the either the brachiocephalic trunk into the right common carotid artery or enters the right common carotid artery. The artery then bifurcates into the left/right internal common carotid and then supplies the brain with oxygen. It then runs back into the superior vena cava, into the right atria, into the right ventricle, and back to the pulmonary arteries. Then to the alveoli, and to the pulmonary veins. Then the RBC with enter the left atria and then enter the left ventricle and be pumped into the aortic arch and enter either the brachiocephalic trunk or enter the left subclavian artery and will enter into the brachial artery, which supplies the bicep muscle with blood, and will drop the oxygen at the bicep muscle.

Flooding also can happen when a levee or other water-controlling structure, sort of a dam, fails. Loss of human life is one among the negative outcomes of flooding. Infrastructure and property destruction. Dangers of landslides, erosion, and road closures. Damage of crops and loss of livestock.The most vulnerable areas to flooding are river floodplains and coastal regions, although flooding can also happen in places with exceptionally lengthy periods of heavy rain.

nonsense
point
silent
frameshift
Answer:
The type of mutation that occurs when one nucleotide in the DNA strand is replaced by another, but the change results in the same amino acid to be placed next in the protein is a silent mutation.
Explanation:
Silent mutations are molecular mutations where, despite a change in one of the DNA nucleotides, this change has no impact on the amino acid sequence that a synthesized protein will have.
An example of a silent mutation is the change in a DNA sequence TTC where a thymine replaces the cytosine, obtaining the TTT sequence:
Normal With mutation
DNA TTC TTT
mRNA AAG AAA
Amino Acid Lys Lys
There was a nucleotide change in the DNA, but the encoded amino acid was the same, which is a silent mutation that does not affect the amino acid sequence of a protein, its structure or function.

So meiosis produces egg or sperm
Answer:
Your answer is correct, it is eggs
Explanation:
In meiosis in females is called oogenesis while in males it is called spermatogenesis so it does produce a little bit of both because it needs to produce the chromosomes for the offspring half male and half female. It also produces 4 gamete cells and around that time can form the offspring which then can form whatever reproductive organ either it's going to be a girl or a boy. But in meiosis, it mostly produces the eggs because the sperm fertilizes the egg hence the whole Meiosis I and II processes.
