Answer:
A and C
Explanation:
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?
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
What is a map? How are maps used, and what is their purpose?
Answer:
Reference maps show the location of geographic boundaries, physical features of Earth, or cultural features such as places, cities, and roads.
Explanation:
Answer:
It is a representation of a place in which the relationship toward time and space is perceived. The purpose of maps are to provide visual representations of the physical features of the Earth to teach and guide. Maps are used to navigate from one place to another, to know the location of an area or region, and to measure distances from certain locations.

In which phases is chromatin condensed?
Answer:
In stage 2
Explanation:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).

Answer:
The answer is D Each part is connected to all the others
Explanation:
While each part is different they interact with eachother to exchange matter and make life possible :) Hope this helps!
The true statement among the given options of the many parts of the biosphere is option D. Each part is connected to all the others.
The biosphere is the ecosphere consist of air, land, water, and rocks all parts where life is found or possible. It is made up of parts of all ecosystems where life exists on earth.
The biosphere has three major parts that interact with one another where life is found:
The lithosphere - the outermost layer of the crust of the earth,The hydrosphere - all the water bodies, ponds. ocean, rivers, and lakes,The atmosphere - includes gases and the air of the earth.All these parts are interconnected with other parts of the biosphere there are no isolated parts.
Thus, the correct answer is - D. Each part is connected to all the others.

The diffusion of water molecules a secectively permeable membrane.
What is Diffusion?The net passive movement of molecules or particles from areas of higher concentration to areas of lower concentration is known as diffusion. There needs to be a concentration gradient for diffusion to happen.
The dissimilarity in the quantity of solutes, particles, or molecules between the two locations will drive them to travel between the two regions.
The gradient created by the uneven particle concentration between two fluids will cause the particles to move in order to balance the discrepancy in concentrations. However, solutes do not migrate in a single direction during the diffusion process.
Therefore, The diffusion of water molecules a selectively permeable membrane.

Many male birds will expend a great deal of energy building nests. Females will mate with the males who build the best nests. This is best described as an example of ____.
a. natural selection
b. sexual selection
c. runaway selection
d. an invasive species
e. disruptive selection
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.

If you’re looking to improve your breaststroke time, mastering the pull-down is a great way to do it. This guide is filled with easy steps to strengthen your race through a powerful pull-down.
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.
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
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.
