The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.
What can happen if a mutation results in aberrant cell division?Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. A tumour can form as a collection of malignant cells enlarges.
hence, skin cancer
Proteins are made from information found in genes, and proteins regulate a number of vital processes, including cell growth. Protein function can be altered by genetic alterations. Certain kinds of genetic changes to proteins result in healthy cells can become cancer.

Note: Your teacher will grade your responses to questions 24‒25 to ensure you receive proper credit for your answers. What circumstances would cause an organism to adapt? In your answer, be sure to explain the differences between both short- and long-term adaptations. Use an example to explain your 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.

Which of the following correctly illustrates a dipeptide and an amino acid in the optimal position to form a tripeptide?
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.

What are ice cores and how are they useful in giving us info about the past?
Answer:
Ice cores are cylinders of ice drilled from ice sheets/glaciers. ice cores tell scientists about temperature, volcanic activity, atmospheric composition, precipitation, and wind patterns.
Explanation:
the thickness of each layer in the core allow scientists to determine how much snow fell in the area during a particular year. the layers are formed by layers of different types of snow. During the summer, when it is light for 24 hours, the snow on the top layer changes texture. When winter arrives, it turns dark and cold again and more snow falls on top of the summer snow, creating distinct layers.

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.
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.
True or False: In Biology, Fitness refers to how fast and strong an individual is. Explain.
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.

Three red square pieces of wood, four yellow square pieces, and five blue square pieces are put into a cloth bag. Four red 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.
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.
What is true about Structure A
please answer if not then that’s fineee
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.

Write a scientific explanation detailing the transfer of energy through an ecosystem. Using the energy pyramid below, determine how much energy will be transferred to each level of the pyramid if the producers have 1 million kilocalories, and explain where the rest of the energy will go.
Answer:
I cannot do math but i can tell you that less than 1 percentage of eneegy is transfered from the primary plant down the pyramid
The amount of energy that will be transferred to each level of the pyramid if the producers have 1 million kilocalories is as follows:
Producers = 1000000 kcal.Primary consumers = 100000 kcal.Secondary consumers = 10000 kcal.Tertiary consumers = 1000 kcal. What is an ecosystem?An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
According to the 10% law given by Lindemann, only 10% of energy gets transferred from one trophic level to the next while the remaining energy is utilized for various life processes of the organisms and some are lost as heat.
The left 90% of the energy is utilized in order to live, grow, reproduce, etc. While some energy may also be lost as heat in the environment.
Therefore, the amount of energy that will be transferred to each level of the pyramid if the producers have 1 million kilocalories is well described above.
