Answer:
✔️Facilitated diffusion does not require any of cell energy.
Explanation:
The above structure A is known as Cell Membrane. It is a permeable membrane through which materials are diffused or transported in and out of the cell.
Option A is true for structure A because facilitated diffusion does not require the cell's energy. Facilitated diffusion is passive transport of molecules or ions across the membrane which is spontaneous.
It is passive because facilitated diffusion does not directly require chemical energy from ATP hydrolysis. What happen is that molecules and ions move down their concentration gradient. This movement reflects their diffusive nature.

True or False: In Biology, Fitness refers to how fast and strong an individual is. Explain.
Answers
Answer:
False
Explanation:
The biological fitness of a person's organism is dependent on their ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population. This is how natural selection affects a population.

The nucleic acid encodes the genetic information unique for each virus, each virus has its own unique info.
The correct statement is that the nucleic acid contains the genetic information the virus needs to avoid detection.
What is the nucleic acid?They are macromolecules or biological polymers present in the cells of living beings that are carriers of cellular information.
Viruses have a protein capsid and some have an envelope, these consist of a single nucleic acid (RNA or DNA) that encodes the viral genome.
Therefore, we can conclude that the correct statement is that the nucleic acid contains the genetic information the virus needs to avoid detection.

Many cells make and use an enzyme, called catalase, to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). What is the effect of catalase on the decomposition of hydrogen peroxide? A. It decreases the activation energy needed to start the reaction. B. It decreases the total energy released by the reaction. C. It increases the total energy absorbed by the reaction. D. It changes the ratio of the amounts of the two products.
Answers
Answer:
A. It decreases the activation energy needed to start the reaction
Explanation:
Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place
When this occurs the minimum amount of energy of reaction to activate or stimulate the the atoms and molecules of the substrate to undergo chemical reaction is lowered.This energy of reaction is celled activation energy.
Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation energy.

In your answer, be sure to explain the differences between both short- and long-term adaptations. Use an example to explain your answers.
Answers
Answer:
Explanation:
Usually, adaption is triggered by the need to survive and reproduce. Short-term adaption is usually caused by a sudden change in circumstance which causes the need for behavior or tactics to change based on previous experience or knowledge. Long term adaption is different, this usually occurs naturally over the course of many decades in order for the species to have better chances of surviving in the changing environment that they are living in.

Hope this helped you :)
There are four phases in the cell cycle. Thus, the four phases are the G1 phase, S phase, G2 phase, and M phase.
What is the cell cycle?Chromosomes and other cell components duplicate to create two copies of themselves over the course of the cell cycle. Following this, the cell divides into two daughter cells, distributing one copy of the duplicated material to each.
G1, S, G2, and M are the four distinct stages of the cell cycle. DNA replication takes place during the S or synthesis phase, and the cell divides during the M or mitotic phase. The other two phases, G1 and G2, sometimes known as the "gap phases," are equally significant but less striking. Further M phase is divided into prophase, metaphase, anaphase, and telophase.
Thus, the G1 phase, S phase, G2 phase, and M phase are the four main phases in a cell cycle.

Answers
The question is incomplete. Here is the complete question.
Three red square pieces of wood, four yellow square pieces, and five boue square pieces are put into a cloth bag. four re round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.
What are the chances that the piece is red round or blue round piece?
a. Cannot be determined
b. 1 chance out of 3
c. 1 chance out of 21
d. 15 chances out of 21
e. 1 chance out of 2
Because:
a. 1 of the 2 shapes is round
b. 15 of the 21 pieces are red or blue
c. There is no way to tell which piece will be picked
d. Only 1 of the 21 pieces is picked out of the bag
e. 1 of every 3 pieces is a red or blue round pieces
Answer: b. 1 chance out of 3
e. 1 of every 3 pieces is a red or a blue round pieces
Explanation: Inside the bag, there will be:
Total of squares: 3 + 4 + 5 = 12Total of round: 4 + 2 + 3 = 9Total of pieces inside the bag: 12 + 9 = 21The question is asking for a round red piece. The probability of that happening is
P(r) = [tex]\frac{4}{21}[/tex]
And a blue round piece:
P(b) = [tex]\frac{3}{21}[/tex]
It is a "OR" probability, so:
P(r or b) = [tex]\frac{4}{21} +\frac{3}{21}[/tex]
P(r or b) = [tex]\frac{7}{21}[/tex] or [tex]\frac{1}{3}[/tex]
Which means 1 out 3 pieces taken out of the bag will be red or blue.

Which of the following correctly illustrates a dipeptide and an amino acid in the optimal position to form a tripeptide?
Answers
The options in the question are shown in the image attached to this answer
Answer:
A
Explanation:
A peptide bond is formed between a carboxylic acid and an amine group. These two functional groups must be in the correct orientation before they can react to form the peptide bond.
If we study the images closely, only the amine group and carboxylic acid in option A are correctly positioned for reaction to take place leading to the formation of a third peptide bond.
Amino acids connect by peptidic bonds to form the linear structures of proteins. In the peptidic bond, the amino group joins the carboxylic group, and a water molecule is released. Among the options, A is the correct one.
-------------------------------------------------------
Amino acids are organic molecules.
They are composed of a central carbon, one hydrogen atom, one carboxyl group (COOH), one amine group (NH₂), and one R group. The composition of the R group is what makes them different from each other.
Proteins are amino acid polymers linearly arranged and connected by peptidic bonds.
The number of amino acids composing the chain and their order determines the primary structure of the protein.
The protein is synthesized from the amino terminus to the carboxy terminus.
The peptidic bond is the union of two amino acids by their carboxyl and amine groups.
When they get together, a water molecule is released, producing a covalent bond ⇒ CO-NH.
Peptidic bonds only form linear structures, with no ramifications, known as peptides.
In this way, every peptide has a free carboxylic group in one extreme and a free amine group in the other extreme.
Among the given options, the correct position of the dipeptide and the amino acid to form a tripeptide is option A.
By looking carefully at the position of the molecules, we can see that this is the only option in which a carboxylic group and an amine group are facing. This orientation is the only one possible for the peptidic bond to form.COOH and NH₂ must get together, releasing a water molecule, and creating the covalent bond CO-NH.
