Atherosclerosis, a particular type of arteriosclerosis, usually involves either complete blockage or severe restriction of blood flow due to high cholesterol and plaque buildup in the arteries. In extreme cases, constricted arteries may collapse from pressure applied outside of the arteries. This can best be explained by:
Atherosclerosis may worsen in the case where there is an increased velocity of the fluid in the already constricted sections of the arteries. This may lead to an increase in blood pressure.
Atherosclerosis is the condition where it leads to the arteries being thickened or hardened. The plaque is deposited on the walls of the artery. With the deposition in the arteries, the artery walls become thickened and lead to the reduction of the blood flow and supply of oxygen to body organs. When the vessels constrict, the flow of blood is decreased. The risk factors are increased blood pressure, obesity, and diabetes. The treatment options could be the consumption of anticoagulants, and medicines to lower blood pressure.

Meiosis II prophase is the stage of cell division in a diploid organism, each consisting of a pair of sister chromatids
There are four crucial processes that take place during prophase II of meiosis II. These include chromatin condensation into chromosomes, thinning of the nuclear envelope, centrosome movement to either pole and re-building of the spindle apparatus. Centrosomes do not exist in every cell, though.
Both of the daughter cells that were created during meiosis I go through meiosis II. The process of cell division starts right away because DNA replication does not occur during this second meiotic stage. Prophase II sets up the cell for meiosis II, which results in the production of four haploid cells, each of which has half the genetic material that was previously present in the original, duplicated diploid cell.

Besides chemical buffers and renal function, Respiratory system regulates the pH of the internal environment.
The three key processes the body employs to control pH are as follows. The first line of defense is a chemical buffer, followed by the respiratory system and, finally, the renal system. Together, these three systems help to maintain the body's pH within that certain range.Compounds that substitute weaker acids or bases for stronger ones. They aid organisms in keeping the pH of bodily fluids within the limited range required for survival by reducing broad pH changes (usually pH 6-8).The bicarbonate buffer mechanism in the respiratory system keeps the blood's pH stable.

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cells?
endoplasmic reticulum
ribosomes
cell membrane
lysosomes
peroxisomes
vesicles
large central vacuole
Golgi complex
cytoskeleton
mitochondria
cell wall
Answer:
large central vacuole
cell wall
Explanation:
Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.
Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.
ANSWER:
Both plants and animals are multicellular, eukaryotic organisms and most of the organelles in cells of animals and plants are similar, such as cell membrane, nucleus, mitochondria, endoplasmic reticulum, and ribosomes.
However, there are some organelles that are only found in plant or animal cells. Organelles that are found only in plant cells include chloroplasts, cell wall, and large central vacuoles. The cell wall provides rigidity and protection to the plant cells, chloroplast help in photosynthesis, and large vacuoles act as storage organelles.
Thus, the correct options are 'chloroplasts, cell wall, and large central vacuole.'

If [e]t was the concentration of lactase in the kinetics trials, what expression gives the concentration of lactase in the commercial preparation of this enzyme?
DF = 1/250 x 1/2
Vt = Et
Vf = final concentration of lactase in the commercial preparation
DF = Vt / Vf
Vf = Vt / DF
Vf = Et / (1/250)(1/2)
Vf = Et x 500
The commercial preparation was first diluted by 1 - 250 to prepare the stock solution, and it was further diluted by 1 -2 by mixing with the substrate stock solution to perform the kinetics experiments.
Therefore, the dilution factor is done when you take whatever you initial volume was - in this case 1mL - and divide it by the new diluted volume - 0.1mL + 25mL. Then we get is 0.1/25.1, which is more easily solved as 1/250.
Since, this was a double dilution, 1mL of the initial dilution was diluted further with 1mL of substrate. So the second dilution factor will be 1/(1+1) = 1/2.

Air displacement plethysmography (ADP) measures the volume of a controlled chamber compared to body volume to determine body fat percentage.
What is Air displacement plethysmography (ADP)?A two-component model called air displacement plethysmography (ADP) measures mass and volume, allowing for an assessment of body density (Db). This allows for the estimate of fat and fat-free mass using body density, which is calculated by dividing mass by volume (FFM).
With air-displacement plethysmography, an object's volume is indirectly determined by calculating how much air it displaces inside a sealed chamber (plethysmograph).

In the study of Gigord and colleagues using Elderflower orchids, the allele frequencies of yellow and purple flowers varied such that when the yellow allele started to become rare, the reproductive success of purple flowers decreased and the reproductive success of yellow-flowered individuals increased in a process known as frequency-dependent selection.
Frequency-dependent selection is an evolutionary process in which the fitness of a phenotype or genotype is dependent on the frequency of that phenotype or genotype in a particular population.
Positive frequency-dependent selection raises the fitness of a phenotype or genotype as it becomes more prevalent.In the case of negative frequency-dependent selection, the fitness of an increasingly prevalent phenotype or genotype diminishes.In a broader sense, frequency-dependent selection involves biological interactions that make the fitness of an individual dependent on the frequencies of other genotypes or phenotypes within the population.

Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane. Active transport is the movement of a substance against a concentration gradient.
What is Osmosis?Osmosis is the automatic net movement or diffusion of solvent molecules through a selectively-permeable membrane from a part of high water possibility (region of lower solute concentration) to parts of low water potential (region of higher solute concentration), in the order that tends to equalize the solute concentrations on the two sides.
It may also describe a physical process in which any solvent moves across a selectively absorptive membrane (permeable to the solvent, but not the solute) by dividing two explanations of different concentrations. Osmosis can be created to do work. Osmotic pressure is described as the external pressure required to be involved so that there is no net motion of solvent across the membrane. Osmotic pressure is a colligative property, suggesting that the osmotic pressure depends on the molar concentration of the solute though not on its individuality.
