Pull-downs are essential to a fast breaststroke race. Without a good pull-down, you have a major disadvantage. You don’t want to start the race behind your opponents! 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.
When substances are constantly moving
back and forth across a cell membrane, the
cell is said to be in a state of?
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.

Meiosis produces which type of cells?
O Haploid somatic cells
Diploid somatic cells
Haploid gametes
Diploid gametes
Answer:
Explanation:
Haploid somatic cells
Answer:
Haploid because during meiosis one cell divides twice to for four daughter cells.
Explanation:
During cellular respiration, the chemical energy from food is transferred into which of the following molecules that can be used as an energy source by enzyme throughout the cell?
A
Ribonucleic acid (RNA)
B
Adenosine triphosphate (ATP)
C
Deoxyribonucleic acid (DNA
D
Triglycerides
Answer:
The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP. The organelle called a mitochondrion is the site of the other two stages of cellular respiration

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.

Where does gravity come from? How does an object's mass shape the fabric of
spacetime?
Answer:
Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
Every object in the universe pulls on the space around it, drawing the fabric of space-time toward its center.
Answer:
gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight.
Every object in the universe pulls on the space around it, drawing the fabric of space-time toward its center. The more massive the object, the more it pulls. ... The physicist John Wheeler captured these odd notions

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.

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.

What is the protozoan and who is the first to observe one?
Answer:
Protozoa is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Anton van Leeuwenhoek was the first person to see protozoa, using microscopes he constructed with simple lenses. Between 1674 and 1716, he described, in addition to free-living protozoa, several parasitic species from animals, and Giardia lamblia from his own stools.
