Functions of different cell organelles:
Nucleus: contains all the genetic material, acts as information center and tells all the organelles what to do, RNA transcription.
Mitochondria: generates energy through respiration
Endoplasmic recticulum (rough): transport and storage of material; (smooth ER): creation of lipids and fats
Ribosome: protein creation by RNA translation
Golgi apparatus: responsible for synthesis, packing and processing of proteins
Chloroplast: responsible for glucose creation (by photosynthesis)
Cytoplasm: is region where all chemical reactions take place and is the jelly like fluid that holds all the organelles in place inside of the cell
lysosome: responsible for breakdown of larger molecules
Flagellum (or flagella): tail like organelle, assists motion
Vacuole: helps in maintenance of homeostasis and stores waste products or other materials like water / food
cell membrane: separates cell from the rest of the environment and controls what comes in and out of the cell
cytoskeleton: supports cell structure

a. natural selection
b. sexual selection
c. runaway selection
d. an invasive species
e. disruptive selection
Answers
Answer:
The correct answer is option B. sexual selection.
Explanation:
Sexual selection is a special type of natural selection proposed by Charles Darwin. According to this type of natural selection in which a particular sex organism chooses the opposite sex member of the species to mate with on the basis of the preferable traits and compete with the other members of the opposite sex.
Here female birds choose those male birds who build the best nests, it is an example of natural selection.

D. Carbohydrates are the main component that makes up cell membranes
Answers
Answer:
D. Carbohydrates are the main component that makes up cell membranes
Explanation:
The main component of the cell membrane is a double layer of phospholipids - molecules with a phosphate head and fatty acid tail. Therefore D is incorrect. There are some carbohydrates in the cell membrane, but they are not the main component.
The statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).
Carbohydrates are biopolymers composed of monosaccharide units linked by glycosidic bonds.Complex carbohydrates (e.g., starch) consist of large branched or unbranched chains of monosaccharides, while simple carbohydrates (e.g., glucose) are monosaccharides.Complex carbohydrates serve as sources of longer energy storage for the cells, while monosaccharides provide energy quickly.The main component of the cell membranes are lipids (i.e., phospholipids and cholesterol).In conclusion, the statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).

Why should muscles not be dissected at the points of origin and insertion
Answers
Answer:
The muscles should not be dissected at the points of origin and insertion due to the fact that the cell structures present here are a typical in nature .
Explanation:
The origin is where the muscle joins the stationary bone. The insertion is where it joins the moving bone. ... At the bone, the fibres of the tendon are embedded in the periosteum of the bone. This anchors the tendon strongly and spreads the force of the contraction, so the tendon won't tear away easily.

1. Form hypothesis: How does temperature affect oxygen concentrations?
If you're correct then I'll give you brainliest! c:
Answers
Answer:
Hello!!! Princess Sakura here ^^
Explanation:
First things first if we are going to form a hypothesis it doesn't matter if it is correct hypothesis are supposed to get tested.
So anyways....
I believe that the solubility of oxygen will decrease as the temperature increase.
I believed that because as temperature increases molecules start to move faster and move farther away from each other.
Temperature can have a significant impact on the concentration of oxygen in various environments. 1) Solubility of Gases, Oxygen Dissociation, Biological Processes.
Here's a step-by-step explanation of how temperature affects oxygen concentrations:
1. Solubility of Gases: The solubility of gases, including oxygen, in a liquid like water is affected by temperature. Generally, as temperature increases, the solubility of gases decreases. This means that at higher temperatures, less oxygen can dissolve in water or any other liquid.
2. Oxygen Dissociation: In the context of the human body, temperature affects the dissociation of oxygen from hemoglobin in red blood cells. As temperature increases, the affinity between oxygen and hemoglobin decreases. This means that oxygen is more readily released from hemoglobin and made available to tissues and organs. Conversely, as temperature decreases, the affinity between oxygen and hemoglobin increases, making it more difficult for oxygen to be released.
3. Biological Processes: Temperature also affects the metabolic rates of organisms. Generally, as temperature increases, metabolic rates increase, leading to higher oxygen consumption. For example, in aquatic ecosystems, warmer water temperatures can enhance metabolic rates of aquatic organisms, leading to increased oxygen demand. Conversely, lower temperatures can slow down metabolic rates and reduce oxygen demand.
It's important to note that the specific effects of temperature on oxygen concentrations can vary depending on the system or environment being studied. Different factors such as pressure, salinity, and the presence of other substances can also influence the relationship between temperature and oxygen concentrations.

When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?
Answers
Answer:
The new solution has a higher concentration than the isotonic saline solution
Explanation:
Here, we want to deduce what has happened in the question.
We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.
Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.
What has occurred is the process of Osmosis
Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.
So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

Laboratory techniques for randomly linking together amino acids typically generate an insoluble polypeptide, yet a naturally occurring polypeptide of the same length is usually soluble. Explain.
Answers
Answer:
The answer has been explained below
Explanation:
The polypeptide has a natural selection due to an optimized sequence. It folds properly. At the outside it has hydrophobic residues. Inside it has polar residues. Now the random sequence of the synthetic peptide is going to be unable to give a good direction to a folding process. This will cause aggregation of hydrophobic side chains on various molecules. Bringing about the polypeptides precipitation from solution. Polypeptides that occur naturally have have the same length when they are in aqueous solution because of amino acid side chains that are present and are large with reactive functional groups.
Why must a forensic anthropologist be able to distinguish between antemortem and perimortem pathology
Answers
Answer: Antemortem describes injuries or pathologies inflicted on the victim before the death. Perimortem refers to any injury associated with the manner of death.
Explanation:
A foresen anthropologist is a person who is dedicated to identifying and studying skeletonized human remains and trying to determine markings on the bones that can elucidate the causes of death. In this way, the anthropologist seeks to learn about the events that occurred by studying the injuries and analyzing evidence left at the scene.
The term antemortem is used to describe injuries or pathologies on the victim before his or her death, which, however, have not caused the person's death. On the other hand, the term perimortem refers to injuries or pathologies associated with the manner of death. That is, it is necessary to distinguish between the two to determine the cause of death of the person. Not only has an antemortem injury or pathology not led to death, but it has no relationship to the event. And a perimortem injury or pathology is fatal, it must be focused on in order to clarify the facts and know how the person died.
Confusing an antemortem pathology with a perimortem one or vice versa, can lead to an erroneous diagnosis of the cause of death.
