3. A branched diagram showing relationships between organisms is a/an– a. amino acid sequence. b. fossil record. c. cladogram. d. DNA sequence.
Answer: your answer would be B
Explanation:
A branched diagram showing relationships between organisms is a cladogram. The correct option is c.
What are the uses of cladogram?An evolutionary tree that depicts the relationships between species' ancestors is called a cladogram.
In the past, cladograms were created using similarities among species' phenotypic or physical characteristics. Today, cladograms can also be created using similarities among organisms' DNA sequences.
A cladogram employs lines that diverge and then converge at a clade, a collection of creatures with a recent common ancestor.
Cladograms come in a variety of shapes, but they all contain lines that diverge from other lines. It is possible to follow the lines back to where they split off.
Cladograms provide a framework for comprehending the rate of evolution of groupings of animals as well as the relationship between their evolutionary history and the planet's changing climate and geography.
Thus, the correct option is c.

Answer:A
Explanation:
Trust me bro
CO2 + H20 + light energy --> C6H12O6 + O2
In the chemical reaction above, what does CoH12O6represent?
Answer:
In the chemical reaction , [tex]C_6H_1_2O_6[/tex] represent glucose.
Explanation:
This chemical reaction is used in the process of photosynthesis . A plant absorbs water, carbon dioxide, and light energy when producing glucose and oxygen during photosynthesis. Since glucose is required for cellular respiration, it is extremely essential. The chemical energy in the glucose molecule is transformed into a shape that the plant can use for growth and reproduction during cellular respiration.
Hence , the answer of the given question is Glucose.

Before a cell divides, the DNA is checked to make sure it replicated correctly. This
piece of DNA is an exact copy of the DNA from which it came. When the parent cell
divided to create two cells, the cell's DNA also divide creating two identical copies of
the original DNA. What will happen if the DNA does not copy itself correctly?
Answer:
the cell will die
Explanation:
its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death

In the liver, excess amino acids are broken down into ____________ and rapidly combine with ____________ to produce urea, which is much less toxic to cells.
Answer:
In the liver, excess amino acids are broken down into ammonia and rapidly combine with carbon dioxide to produce urea, which is much less toxic to cells.
Explanation:
The correct answer to the given quested about Urea Cycle is Ammonia and Carbon dioxide respectively and the complete statement will be "In the liver, excess amino acids are broken down into Ammonia and rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells."
What do you mean by Urea Cycle?The urea cycle, commonly referred to as the ornithine cycle, is a series of metabolic processes that converts ammonia into urea (NH2)2CO (NH3).Highly poisonous ammonia is transformed into urea by rapidly combining with carbon dioxide via the urea cycle for elimination. Five years before the TCA cycle was found, this cycle was the first to be identified as a metabolic process. Later, Ratner and Cohen provided a more thorough explanation of this cycle.Thus we can conclude that in the liver, excess amino acids are broken down into Ammonia which is highly toxic to cells and that ammonia rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells.

15. Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 30 percent solute solution. Would the blood cell get bigger or smaller? Why? In your explanation, you must tell me which area has the hypotonic solution (inside the blood cell or outside the blood cell), which area has the hypertonic solution (inside the blood cell or outside the blood cell), and which direction the water would be moving (into the cell or out of the cell).
Answer:
Smaller
Explanation:
The human blood cell has a smaller percentage of solute concentration than the solution it was placed into. This means that the cell is hypotonic in comparison to the solution, and the solution is hypertonic compared to the cell. When a cell is placed in a hypertonic solution it undergoes crenation, meaning it shrivels up. Water moves from the lower solute concentration to the higher solute concentration. The water inside the cell moves outside to the hypertonic solution. This causes the cell to become smaller.
Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. Explain the results shown in your diagram.
Answer:
Because the offspring of a male and female are always going to be xx, xx, xy, or xy.
Explanation:
Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.
So we can write the this out in a punnet square as(link down below).
After you see the visual, you will find that the genotypes are xx, xx, xy, xy.
As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.
So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.

3. The presence of Malaria in many countries has been eradicated and even in parts of Africa, the incidence of Malaria has been reduced substantially. Without endemic malaria from Africa, the sickle cell mutation is purely disadvantageous. What do you think will happen to the percentage of people carrying the Sickle Cell gene over time under the pressures of natural selection
Answer:
The percentage of people carrying sickle cell gene increases.
Explanation:
People carrying the Sickle Cell gene have low chance of Malaria because the sickle cell enables the body to detoxify abnormal red blood cells from the body. When the malarial parasite attacks on the cells of the body, the molecular machinery for cleaning up the waste is already present in the body. Those places where malaria is common, the people having sickle cell because the sickle cell show resistance against malarial disease.

An isometric exercise is one in which the joint angle does not change during the application of muscle force. For instance, you can join your hands together, pushing down with one hand and pushing up with the other. In each arm, the muscles that provide the force are connected to the bones of the arm by tendons. If you increase the forces but keep the angles the same, the muscles will still contract. Explain how this is possible.
The disease multiple sclerosis makes it more difficult for signals from the brain and spinal cord to travel along nerve fibers. How will multiple sclerosis
affect other body tissues?
O Connective tissue will increase its fat storage.
O Muscle tissue will contract uncontrollably.
Epithelial tissue will lose the ability to protect against infection.
Tendons and ligaments will become brittle and break.
Answer:
O Muscle tissue will contract uncontrollably.
Explanation:
Multiple sclerosis, also known as encephalomyelitis disseminata, is a disease that affects the brain and spinal cord. Some of the most common symptoms of multiple sclerosis include vision problems, arm or leg movement and balance. This disease occurs when the immune system attacks the myelin sheath that covers nerve cells in the brain and spinal cord, causing inflammation and subsequent damage of the sheath and the nerve fibers it surrounds. Multiple sclerosis may cause muscle twitches when nerve fibers are damaged, thereby disrupting the signaling between nerves and muscles.

What are the two main ways bacteria cause illness?
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
C. By changing the genetic material inside your cells
D. By breaking down your cells for nutrients
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.
