Cellular respiration is a series of chemical reactions that convert the energy in food molecules into energy stored in the molecule ATP. Aerobic respiration requires the presence of Oxygen and releases water and carbon dioxide as waste products.

Explanation:

A sharp increase in capillary hydrostatic pressure would directly cause an increase in fluid movement to the interstitial spaces.

Capillary hypertension causes the production of a protein-poor ultrafiltrate, which when it enters the interstitial space increases the amount of the interstitial fluid.

A rise in small artery, arteriolar, or venous pressure raises capillary hydrostatic pressure, which favors filtration. Fluid filtration will be reduced if the hydrostatic pressure gradient (PC - Pi) reduces due to an increase in interstitial pressure. Large rises in tissue interstitial pressure, on the other hand, can cause tissue damage and cellular death.

Edema occurs when plasma oncotic pressure falls, hydrostatic pressure rises, capillary permeability rises, or a combination of these variables occurs. When lymphatic flow is impeded, edema can develop.

While giving a warning call may put the individual squirrel at risk, the benefits of warning the rest of the group can outweigh this cost. Additionally, some research has suggested that animals that give warning calls are less likely to be targeted by predators, as the calls can alert the predator to the presence of the group and make it more difficult for the predator to catch any individual member of the group. Overall, giving warning calls can be an effective strategy for increasing the survival chances of the group as a whole.

Based on the theory of island biogeography, the statement that is most likely true about small islands when compared to large islands is that the rate of immigration is lower for small islands than for large islands.

Island theory of biogeography explains differences in species diversity based on island size (for example, large islands tend to have more of a given species category than small islands). This means that the number of species found on an island will be determined by the area of ​​the island.

a) The mass of the oxygen is 1.97 g

b) The percent yield is 90.4 %

c) The mass of the oxygen is 1.55 g

We know that the percent yield has to do with the amount of the reactants that has been converted into products in the given reaction. In this case, the reaction that we are dealing with is the decomposition of the potassium oxo chlorate V molecule.

Now we have that;

a) Number of moles of the chlorate = 5 g/122.5 g/mol

= 0.041 moles

If 2 moles of the chlorate produces 3 moles of the oxygen

0.041 moles of the chlorate produces 3 moles * 0.041 moles/ 2 moles

= 0.0615 moles

Mass of the oxygen produced = 0.0615 moles * 32 g/mol

= 1.97 g

b) Percent yield = Actual/Theoretical * 100/1

=  1.78/1.97 * 100/1

= 90.4 %

c) For a percent yield of 78.5% =

% yield = (1.78 g / theoretical yield) × 100%

To calculate the percent yield, you need to know the actual yield and the theoretical yield of the reaction.

In this case, the actual yield is given as 1.78 g of O₂. The theoretical yield represents the maximum amount of product that can be obtained under ideal conditions.

To calculate the theoretical yield, you need to know the balanced chemical equation for the reaction. Assuming the reaction is complete, the coefficients of the balanced equation can be used to determine the stoichiometry of the reaction.

For example, if the balanced equation is:

2 A + 3 B → 4 C + 2 D

Then, you can use the stoichiometry to find the theoretical yield. Let's say the molar mass of O₂ is 32 g/mol. In this case, we need to calculate the moles of O₂ using the given mass of 1.78 g:

moles of O₂ = mass of O₂ / molar mass of O₂

Next, we need to use the stoichiometry to find the moles of the desired product. Let's assume that O₂ is the limiting reactant and that it is completely converted to the product. From the balanced equation, we can see that 4 moles of C are produced for every 2 moles of O₂:

moles of C = moles of O₂ × (4 moles of C / 2 moles of O₂)

Now that we have the moles of C, we can calculate the theoretical yield of C in grams by multiplying the moles by the molar mass of C.

theoretical yield of C = moles of C × molar mass of C

Finally, we can calculate the percent yield using the formula:

% yield = (actual yield / theoretical yield) × 100%

Substituting the values we calculated:

% yield = (1.78 g / theoretical yield) × 100%

Please note that without the balanced chemical equation and additional information, it is not possible to provide a specific numerical answer for the percent yield.

The restriction enzymes when combined with the DNA containing restriction sites lead to cuts at those sites yielding restriction fragments. The second statement is correct.

The restriction enzymes are the enzymes that recognize specific sites known as restriction sites. These are enzymes that are found in bacteria and this feature is used as a modern biotechnology tool for genetic editing.

There are two ways the ends are formed after the action of a restriction enzyme. It can form blunt ends or sticky ends. The sticky ends have a region at the end that is single-stranded. This region can then join according to the complementary base pairing with another strand having complementary sticky ends.  

If it is assumed that the RE (restriction) enzyme is not interrupted during the generation of restriction fragments, the resulting restriction fragments would not yield more restriction fragments when re-incubated with the RE enzyme.

Darwin proposed a theory which describes that a species can change over time, that a new species come from the pre-existing species, and that all the species share a common ancestor. In this model of Darwin, each species has its own unique set of heritable or genetic differences from the common ancestor, which have been accumulated gradually over a period of very long period of time.
