Which of the following is carried out by vesicles?
O Synthesizing proteins
O Facilitated diffusion
Breaking down substances within the cell
Organizing organelles prior to division
Answer:
breaking down substances within the cell
Explanation:
there are many different types of vesicles, Peroxisomes and lysosomes are both types that break down substances in the cell
The correct statement about vesicles is "Breaking down substances within the cell"
Vesicles are an organelle isolated from the cytoplasm by a membrane-like lipid layer.
Its function is to store, move and process products and cellular waste.Endocytosis and exocytosis transports are characterized by the fact that the substances move through vesicles.The vesicles incorporate substances (endocytosis) and through degradation, they expel large particles that cannot cross the plasma membrane, this mechanism is exocytosis.Therefore, we can conclude that the cell incorporates, inside the vesicle, particles from the extracellular environment and also through the vesicles it releases degradation products to the extracellular environment.

What is the argument against taking persistent vegetative state patients off of life support?
Answer:
An argument could be that there have been many instances where people on life support or in a vegatative state have 'woken' up and gotten better after many years. So, taking someone off life saving machines could be taking away their chance of getting better and their chance of surviving. Since the person is not dead, some may even see it as murder.

how and why does DNA change during meiosis
Answer:
When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.

In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. It results in a pattern change between expiratory and inspiratory flow. Explain changes you observed in the recordings you obtained. 1 pts Enter your answer here
Answer:
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.
The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive basically depends on the inhalation because of elastic recoil that causes a decrease in volume.
During this, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle whereas quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.
What is Breathing?Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

Writing Assignment So, you have learned about how the denaturation of proteins works during lecture, and you have seen examples in these videos. Now you will write a 2-3 page discussion of protein denaturation putting all that together Make sure you cover both the academic side (lecture knowledge) and practical side (what is done and observed in the lab). Make sure the answers to the following questions are contained in your report. Do NOT just answer them separately, but rather incorporate them seamlessly in your writing. This is a very broad topic, so comprehensive coverage is hardly expected, but you should demonstrate a good beginner's understanding. As usual, reference any and all resources you use.
a. What are the various levels of organization that any protein structure may have that gives it its 3-dimentional shape?Which of these changes during denaturation?
b. For each change made to a protein solution that you have seen or read about how might it affect the interactions that are involved in a protein's shape?
c. What is the difference between precipitation of a protein and its denaturation? How might you tell the difference?
d. If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if it were the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (Consider the enzymes that are active in your stomach, such as pepsin-discussed in Wikipedia.)
e. For changes that precipitate a protein, are some more likely than others to be denaturation?
f. Etc. If you find one aspect of what you've see more interesting, go ahead and learn more and expand that section of your report and keep the other sections more basic.
Solution :
Denaturing may be defined as the process where the protein they lose their shape and their function because there is a change in the pH level or in the temperature. Although the amino acids sequence also known as primary structure, it does not change. But the shape of the protein might change a little bit so much that it can become dysfunctional in which protein is considered to be denatured.
The enzyme, Pepsin, the breakdown protein in our stomach only operates at a very low pH level. At higher pH level, the pepsin's configuration the way the polypeptide chain is being folded up in a 3 dimension begins to change. The pH level of the stomach is maintained at a low level to ensure that pepsin continues for the digest protein and that it does not denature.
There are 4 levels of the protein structure --- they are the primary, the secondary, the tertiary and the quaternary.
The primary protein is a particular sequence of amino acids in each of the polypeptide chain that makes the protein. The final protein structure depends on this sequence.
Secondary structure arise from the interactions between the neighboring or nearby the amino acids as polypeptide starts folding into 3D form.
The tertiary structure is the most important of structural levels in determining.
The quaternary structure also applies to the proteins made from more than one polypeptide chain.
To approximate the actual concentration of enzymes in a bacterial cell, assume that the cell contains equal concentrations of 1,000 different enzymes in solution in the cytosol and that each protein has a molecular weight of 100,000. Assume also that the bacterial cell is a cylinder (diameter 1.0 m, height 2.0 m), that the cytosol (specific gravity 1.20) is 20% soluble protein by weight, and that the soluble protein consists entirely of enzymes. Calculate the average molar concentration of each enzyme in this hypothetical cell.
Answer:
2.4 × 10⁻⁶ M
Explanation:
Molar concentration = no of moles of solute (enzymes)/volume of solvent(cystosol)
Let V = volume of solvent = volume of cystosol = πd²h/4 where d = diameter of cell = 1.0 m and h = height of cell = 2.0 m
Concentration of enzymes, C = n/V where n = no of moles of enzymes
Also, n = m/M where m = mass of all enzymes and M = molecular weight of protein = 100,000
Note that the solvent for the enzymes is cystosol, since they are dissolved in it.
Density of cystosol,ρ = specific gravity of cystosol in g/cm³ = 1.20 g/cm³.
Now, ρ = m'/V where m = mass of cystosol and V = volume of cystosol
m' = ρV
m' = 1.20V
Given that 20 % of the cystosol is protein and all protein are enzymes, the mass of enzymes is thus m = 0.2m' = 0.2 × 1.20V = 0.24V
C = n/V
= m/MV
= 0.24V/100000V
= 2.4 × 10⁻⁶ mol/cm³
= 2.4 × 10⁻³ mol/dm³
= 2.4 × 10⁻³ M
This is the concentration of all the 1000 enzymes.
So, the concentration of one enzyme is 2.4 × 10⁻³/1000 M = 2.4 × 10⁻⁶ M

Why aren't there many large carnivores?
Answer:
Technically, the largest ever marine predator known thus far - the blue whale - is, for now, alive and well, but I know what you mean. You’re not talking about filter-feeders, or fish-eaters, you mean macropredators.
The last truly enormous macropredator in our oceans was probably Carcharocles megalodon, which went extinct about 3.6 million years ago. Other recent examples include the terrifying sperm whale Livyatan melvillei (which disappeared 8.9 mya) and other megatoothed sharks like C. chubutensis.
So, why did the giants go away? The answer, in truth, is likely multi-faceted. Here are some major promising hypotheses, or at least contributing factors:
Whales have declined. Giant sea carnivores like C. megalodon and Livyatan relied on marine mammals - specifically baleen whales. During the Pliocene, the Americas connected and the Central American Seaway was closed. This seems to have triggered a significant decline in the diversity of tropical whales, and would thus limit food availability for huge, energy-hungry predators.
Things got too cold. The extinction of megalodon and other giant ocean predators roughly coincides with the trend of decreasing temperatures the Pliocene brought. Giant sharks in particular, not being fully warm-blooded, would suffer from this, and it would also mean a decline in food supply. You can even see a sudden cold snap just about when Carcharocles went extinct, 3.6 mya.
Smaller predators outcompeted them. The niche of Carcharocles and the macroraptorial sperm whales is arguably still filled today - by the killer whale. Many orca pods specialize in hunting whales or other marine mammals. However, killer whales and their ancestors were perhaps more opportunistic, fast, intelligent and indeed adaptable than the massive, solitary hunters.
Ironically, the largest ever marine predator owes its existence to the demise of the largest ever marine macropredators. Since the extinction of macroraptorial sperm whales and Carcharocles megalodon, baleen whales have been gradually increasing in size, for they no longer need to be as fast and agile. Because of this, we have the privilege of sharing our world with the largest animal known to have ever lived - the blue whale.
