Answer:
For a codominant trait, a heterozygous organism will actually express both alleles. This means that the distinct phenotypes produced by each allele can both be observed.
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.

The French biologist Lamarck hypothesized that “organisms could acquire traits making them better adapted to their environment and pass these on to their offspring” which is not the same theory stated as Darwin. Why does Darwin make a more sound argument for his support of the process of evolution than Lamarck?
Answer:
Darwin suggests that the strongest survive and adapt to produce even stronger more adaptable offspring
Which process must the cell undergo to have genetically different cells at the end of cell division?
Answer:
meiosis (soso srry if im wrong)
Explanation:
Which of these is NOT an example of a pure substance? A a tablet of the element known as calcium
B a glass of muddy water
C a glass of ice and water
D a chemical compound known as aluminium oxide
Answer:
a glass of muddy water
Explanation:
Pure substances contain only one element or compound.
Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.
The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.

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.

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'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.

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.

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.

Describe as you travel through the different types of blood vessels (capillaries, arteries, and veins) as you make your journey through the different types of circulation (pulmonary/lungs, coronary/heart, and systemic/body) and reach the cells of the body.
Answer:
Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body. The journey might begin and end with the heart, but the blood vessels reach every vital spot along the way. These arteries, veins, and capillaries make for a vast network of pipes. If you were to lay out all the blood vessels of the body in a line, they would stretch for nearly 60,000 miles. That’s enough to circle the earth almost three times!
1. The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries
The different types of blood vessels and their layers
Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances. The capillaries also connect the branches of arteries and to the branches of veins. The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima. These layers surround the lumen, the hollow interior through which blood flows.
2. Oxygenated Blood Flows Away from the Heart Through Arteries
The major arteries and branches of the body
The left ventricle of the heart pumps oxygenated blood into the aorta. From there, blood passes through major arteries, which branch into muscular arteries and then microscopic arterioles. The arterioles branch into the capillary networks that supply tissues with oxygen and nutrients. The walls of arteries are thicker than the walls of veins, with more smooth muscle and elastic tissue. This structure allows arteries to dilate as blood pumps through them.
3. Veins Carry Blood Back Toward the Heart
The superior and inferior vena cava
After the capillaries release oxygen and other substances from blood into body tissues, they feed the blood back toward the veins. First the blood enters microscopic vein branches called venules. The venules conduct the blood into the veins, which transport it back to the heart through the venae cavae. Vein walls are thinner and less elastic than artery walls. The pressure pushing blood through them is not as great. In fact, there are valves within the lumen of veins to prevent the backflow of blood.
4. Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries
Click to play an animation of blood flow through capillaries
Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation. Elsewhere in the body, oxygen and other nutrients diffuse from blood in the capillaries to the tissues they supply. The capillaries absorb carbon dioxide and other waste products from the tissues and then flow the deoxygenated blood into the veins.
5. The Constant Pumping of the Heart Maintains Blood Pressure and Supply Throughout the Body
Click to play an animation of blood pressure measurement
The blood moving through the circulatory system puts pressure on the walls of the blood vessels. Blood pressure results from the blood flow force generated by the pumping heart and the resistance of the blood vessel walls. When the heart contracts, it pumps blood out through the arteries. The blood pushes against the vessel walls and flows faster under this high pressure. When the ventricles relax, the vessel walls push back against the decreased force. Blood flow slows down under this low pressure.
