What are the characteristics of muscle?
Answer:
-It thrives during times of intense, or sustained, physical activity.
-The need for increased carbohydrates to sustain that extra level of exertion.
-It's the primary tissue in the human body with herculean strength which makes it very efficient at doing heavy work.
-It becomes rigid when it becomes depleted of oxygen, which is what causes cramping around muscles during intense bouts of exercise where you are doing something like sprinting or weight lifting too fast for your body to keep up through oxygenation alone. This is called anaerobic glycolysis - where there isn't enough oxygen present to use all the sugars being metabolized by your muscles even NEEDED by their quick contractions.
When investigating competition between two organisms what is important that they both have/require

Pseudopodia is temporary .........
a. cell
b. cilia
c. part of cell
d. locomotary organ.
Pseudopodia are temporary projections of the cell membrane of eukaryotic cells. And by temporary, it means that it is not a fixed structure. Single-celled organisms characterized by the ability to form arm-like protrusion that can be protracted or retracted are referred to as amoebae.

There are many points during the cell cycle when the process of division may stop because of a problem. Sometimes the process doesn’t stop. Summarize the function of apoptosis in the cell cycle.(1 point)
to destroy damaged or old cells
to destroy damaged or old cells
to facilitate cell reproduction before the cell cycle restarts
to facilitate cell reproduction before the cell cycle restarts
to allow the cell to rest before the cell cycle restarts
to allow the cell to rest before the cell cycle restarts
to repair damaged or old cells
to repair damaged or old cells
The function of apoptosis in the cell cycle is to destroy damaged and/or old cells. In this case, we can consider that the first answer option is the correct option.
Apoptosis is a programmed death, where the cells promote massive destruction when they "realize" that they can create problems for the organism.
This process takes place as follows:
A cell retraction begins so that the cell cannot adhere to other cells or substances.The chromatin becomes condensed.The cell membrane elongates, forming structures known as "blebs."The cell nucleus disintegrates completely.The blebs break off, forming an apoptotic body.The apoptotic body is unprotected from the action of phagocytes that can destroy the molecule.More information:

Which of the following is a complementary base pair for DNA?
Adenine and thymine
Guanine and adenine
Guanine and uracil
Cytosine and thymine
Answer:
adenine and thymine
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.

The number of bacteria in saliva samples was determined by collecting the saliva, making serial dilutions, and inoculating nutrient agar by the pour plate method. The plates were inoculated aerobically for 48 hours at 37°C.
What can you conclude from this data? Why?
Answer:
3.7808=5c
Explanation:
According to the given data, mouthwash A decrease the growth of the bacteria in saliva due to antiseptic ingredients, B decrease the maximum, and C is the least effective.
How bacteria present in the saliva are collectively removed?In the saliva, there are some enzymes that can remove by killing certain types of bacteria, by using mouthwash it can be removed according to the efficiency of the mouthwash.
In the experiment number of bacteria in saliva samples was determined by collecting the saliva, after serial dilution, bacteria are inoculating in nutrient agar by the pour plate method, and these plates were inoculated aerobically for 48 hours at 37°C.
The complete data is attached in the image below.
Therefore, Mouthwash B > Mouthwash A > Mouthwash C is effective to remove bacteria.

What benefits do you see in genetic testing, if any?
What concerns do you have about genetic testing, if any?
Would you want doctor prescribed genetic testing/screening done?
Would you want voluntary genetic testing/screening done (e.g. 23 and me)?
Answer:
Genetic testing has potential benefits whether the results are positive or negative for a gene mutation. Test results can provide a sense of relief from uncertainty and help people make informed decisions about managing their health care. For example, a negative result can eliminate the need for unnecessary checkups and screening tests in some cases. A positive result can direct a person toward available prevention, monitoring, and treatment options. Some test results can also help people make decisions about having children. Newborn screening can identify genetic disorders early in life so treatment can be started as early as possible.

A scientist is researching the biochemical reactions that take place during digestion in frogs. The scientists is simulating frog digestion in a lab setting and adds the enzyme, lipase, to the substance to be broken down.
How will the enzyme speed up this chemical reaction?
A.The enzyme will lower the activation energy of the chemical reaction.
B.The enzyme will be reproduced as a result of a chemical reaction.
C.The enzyme will increase the activation energy of the chemical reaction.
D.The enzyme will add heat to the chemical reaction.
Answer:
Your answer should be A.) The enzyme will lower the activation energy of the chemical reaction. I hope this helps you! :D
The enzyme will lower the activation energy as it will increase the rate of the reaction. So the correct option is A.
What is the activation energy of enzymes?A chemical reaction's rate and activation energy are tightly correlated. Particularly, the chemical reaction will occur more slowly the greater the activation energy. This is due to the fact that molecules can only finish the reaction after climbing the activation energy barrier. Less molecules will have enough energy to cross the barrier at any one time as the barrier rises.
Similar to the hydrocarbon combustion example, the majority of chemical reactions that occur in cells have activation energy that is too high for the processes to progress considerably at room temperature. This first appears to be a concern since a spark inside a cell cannot be ignited without inflicting harm.
Fortunately, it is feasible to reduce a reaction's activation energy and so speed up the process. Catalysis is the process of accelerating a reaction by lowering its activation energy, and a catalyst is a substance that is introduced to do so.
Therefore the correct option is A.
