Why is it Important that cell membrane contain openings into cell ?
Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.
Which process results in two identical cells?
meiosis
replication
fertilization
mitosis
Answer:
d
Explanation:
The process that results in two identical cells is known as Mitosis. Thus, the correct option for this question is D.
What is Mitosis?Mitosis may be defined as a type of cell division through which two identical daughter cells are produced from a parental cell. These daughter cells are genetically identical to their parental cells and are mostly diploid in nature.
While the process of meiosis typically produces four daughter cells from a parental cell. These daughter cells are not genetically identical to their parental cells. These cells are haploid in nature.
The process of fertilization may be defined as when two distinctive gametes are fused together in order to produce a zygote. While replication is the duplication or synthesis of genetic material during the S-phase of Interphase.
Therefore, mitosis is the process that results in two identical cells. Thus, the correct option for this question is D.

Explain why the failure of one organ or organ system can affect the function of other body systems in an organism.
Answer:
You start to feel bad!
Explanation: When the balance is disrupted, the body system may not function properly.
When balance is disturbed the body function will not work properly.
What is organ system?
The body is organized at many stages that progress together. Organ systems are made up of tissues, which in turn are made up of tissues and organs.
The coordinated activity of an organ system's organs determines how well it functions. To process food, for instance, the digestive system's organs work together.
The coordinated operation of all organ systems, frequently coordinated by the endocrine and nervous systems, is necessary for the organism to survive.
The body is organized at many stages that progress together. Organ systems are made up of groups of organs with linked tasks. Organs are structures made up of two or more tissues arranged to perform a certain function.

Which will increase the rate of a chemical reaction?
adding a catalyst
decreasing the pressure
decreasing the temperature
removing a catalyst
Answer:
Addition of a catalyst
Explanation:
A catalyst tends to alter the rate of a chemical reaction thereby increasing the rate of the reaction
Adding a catalyst will increase the rate of a chemical reaction. Therefore, option (A) is correct.
What are the functions of catalyst?A substance known as a catalyst is one that, without being consumed during the reaction, accelerates or reduces the temperature or pressure required to initiate a chemical reaction.
A substance which when utilized in limited quantity in responses changes the pace of a reaction without being consumed in the actual response is known as an impetus and this peculiarity is known as Catalysis.
Without actually participating in the reaction, catalyst is used to speed it up. The reaction rate is sped up by catalyst, but the equilibrium constant remains unchanged.

Students in a science class were asked to investigate how missing or damaged organelles affect cellular homeostasis for cells found in muscle tissues. Which of the following questions should they ask to determine if these muscle cells are functioning properly? A. At what rate do the ribosomes of the cell need to work to produce enough glucose to meet the high energy needs of the cell? B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? C. At what rate do the chloroplasts of the cell need to capture enough sunlight to meet the high energy needs of the cell? D. At what rate does the cell wall need to break down its carbohydrate structure to meet the high energy needs of the cell?
Answer:
B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?
Explanation:
Organelles are specific in their functioning and hence, each organelle contributes its own quota to the cell's proper functioning. According to the question, a muscle tissue is being worked on to determine the effect of a missing or damaged organelle on its cell.
Mitochondria are organelles found in all eukaryotic living cells. They are the organelles responsible for the synthesis of ATP (energy) used by the cell as a result of the glucose that gets converted in them during cellular respiration.
Therefore, to determine if the muscle cells are functioning properly, the question that: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? should be asked.
Note that, Chloroplast and cell wall are not found in muscle cells, which is an animal cell. Likewise, ribosomes are not organelles for synthesis of glucose.

What usually happens when new evidence is discovered that is not already explained in an existing theory? Group of answer choices The existing theory is discarded, and a new theory is developed. Scientists choose sides and either support the existing theory or the new evidence. The theory is adapted to account for the new evidence.
Answer:
The best answer to the question would be - The theory is adapted to account for the new evidence.
Explanation:
If a piece of new scientific evidence is discovered for an already existing scientific theory that is already not explained in the theory it would be lead to the modification of the theory in order to make the theory so it can explain the newly find evidence.
If the theory can not be modified to fit the new scientific evidence the given theory is rejected ultimately. But more often theories are modified to explain the newer findings.
Thus, the best answer to the question would be - The theory is adapted to account for the new evidence.
What usually happens when new evidence is discovered that is not already explained in an existing theory is that more scientific evidence would be gathered about it.
Needless to say, a scientific theory may be modified and rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then requiredAccepted theories may however, be modified or overturned as new evidence Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more.
