What is an biotic organism in a Forrest?
Read the scenario and examine the table.
Ivan wants to test how the amount of water consumed each day affects the number of facial blemishes people receive over a month. He gathers 12 people and divides them into 3 groups. He keeps everything the same for each group except for daily water and food intake. Throughout the month, Ivan tallies the number of facial blemishes each individual receives. The table details how Ivan changed the independent variables for each group.
Note: Group 1 is Ivan's control group.
What error did Ivan make in the design of his investigation?
A.) Ivan did not record the results for the dependent variable in a data table.
B.) Ivan did not determine the average number of blemishes received.
C.) Ivan tested more than one independent variable at a time.
D.) Ivan had the individuals in the control group consume water.
The answer is C.) Ivan tested more than one independent variable at a time.

Chromatin coils tightly around itself to make chromosomes as the cell gets ready to divide.
What do human chromosomes do?Long segments of DNA are carried by chromosomes, which are organelles that can be found within the nucleus of cells. The material that houses genes is called DNA. It serves as the base for the human body. Additionally, protein found in chromosomes aid in the appropriate structure of DNA.
What are chromosomes and what do they do?The highest possible level of both protein and DNA organization is seen in chromosomes. Chromosomes' primary mission is to carry DNA & pass genetic material from one generation to the next. Cell division involves the critical function of chromosomes. They guard against tangles & damage to the DNA.

describe the interior structure of a mitochondrion. HELP ME PLEASE !!!!!
Answer:
mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and it contains it like a skin. The Inner membrane folds over many times and creates layered structure called cristae.
Figure 1 represents a segment of DNA. radiation can damage the nucleotides in a DNA molecule. to repair some types of damage, a single nucleotide can be removed from the DNA molecule and replaced with an undamaged nucleotide. which of the four labeled bonds in figure 1 could be broken to remove and replace the cytosine nucleotide without affecting the biological information coded to the DNA molecule?
Answer:
This question is incomplete as it lacks options; the options are:
A) Bond X only
B) Bond W only
C) Bonds Y and Z at the same time
D) Bonds W and Z at the same time
The answer is C. Bond Y and Z at the same time
Explanation:
A DNA molecule is a double-stranded molecule made up of nucleotide units. According to this question, radiation can damage the nucleotides in the DNA molecule. However, the cell can repair this DNA molecule by removing the single damaged nucleotide and replacing it with an undamaged one.
In this case, the cytosine nucleotide is the damaged nucleotide. To repair this DNA in the image, the covalent bond holding the one nucleotide to another in one of the DNA strands must be broken.
The sugar-phosphate bonds as represented by letters Y and Z are the bonds that could be broken to replace the cytosine nucleotide by an undamaged one, without affecting the biological information coded to the DNA molecule. The bonds holding the neighboring nucleotides are also broken during the repair process. Note that, this form of repair is called BASE EXCISION REPAIR
The bond in figure 1 could be broken to remove and replace the cytosine nucleotide without affecting the biological information coded to the DNA molecule is C. Both Bond Y and Z at the same time.
It should be noted that a DNA molecule is simply referred to as a double-stranded molecule that's made up of nucleotide units. Radiation can damage the nucleotides that are in the DNA molecule.
Through the removal of the single damaged nucleotide and then replacing it with an undamaged one, the DNA molecule can be repaired. Based on the diagram, the cytosine nucleotide is the damaged nucleotide, therefore, in order to repair it, the covalent bond that's holding the nucleotides together must be broken.

Describe the differences in strength between ionic bonds, covalent bonds, hydrogen bonds, and Van der Waals interactions.
Answer:
A hydrogen bond (or H-bond) results when a hydrogen atom that is covalently bound to an electronegative atom (e.g. O, N, S) is shared with another electronegative atom. ... They are stronger than the van der Waals interactions, but weaker than covalent or ionic bonds.

What happened to the eggplant after adding salt?
Answer:
Salting eggplant is often explained on two points: The first point contends that eggplants can be quite bitter, and salting helps cut the bitterness. (No, salt doesn't draw out bitterness. It just helps hide it.) Second, salting eggplants reduces the sponginess and leaves you with a creamy, silky texture.

What would happen to the fruit fly population in the locker if the apple were removed from that ecosystem?
Fruit flies are the insects that belong to the order, Diptera and are attracted to ripe and decaying fruit sources. If apple is removed from the ecosystem then the population of flies decreases.
What is an ecosystem?An ecosystem is said to be a biological community that is defined by the presence of both abiotic and biotic factors. It involves the interaction between living and non-living things that are linked through the food chain or the biogeochemical cycle.
The population of the fruit flies in the ecosystem depends on and interacts with the fruits that are ripe and decaying. They feed on those fruits. If the fruit like apples is removed then it will affect the fly population decreases as they were dependent on them for survival.
Therefore, the population of fruit flies decreases.
