Answers
Answer/Explanation:
Recall:
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1

Hydrogen bonding is primarily responsible for the high ______ of water.
a. freezing point
b. boiling point
c. conductivity
d. polarity
Answers
The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds
Explanation:
Therefore, option b is correct.Hydrogen bonding is primarily responsible for the high boiling point of the water. Thus, the correct option is B.
What is Hydrogen bonding?Hydrogen bonding is an interaction which involves a hydrogen atom that is located between a pair of other atoms such as nitrogen, oxygen, and fluorine which have a high affinity for electrons, and such a bond is weaker than an ionic bond or a covalent bond but are stronger than van der Waals forces and dispersion forces.
Hydrogen bonding is primarily responsible for the high boiling point of water solvent. Hydrogen bonding is a strong affinity. Hydrogen bonding is created when a hydrogen atom is bonded to an electronegative atom by approaching a nearby electronegative atom.
Therefore, the correct option is B.

Why is diffusion such an efficient process
for all cells?
A. It does not require energy.
B. It occurs so quickly.
C. The high amount of energy used during diffusion is offset by
the amount it creates.
Answers
Answer:
A.
Explanation:
Diffusion does not require energy. It's depends on the concentration gradient of the two molecules.
Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the migration of substances from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
Diffusion does not require any type of energy for the movement of ions, molecules, or substances. It is a very feasible form of migration of substances.
Diffusion is a type of passive transport and hence takes place in a dropping manner without any expenditure of energy.
Therefore, Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.

A biologist studies a population of anteaters living in a large nature reserve. The reserve is surrounded by farms where anteaters are not safe, but the reserve is a perfect place for anteaters: there are few predators and lots of ants. The biologist counts the number of anteaters in the reserve every year for twenty years and finds the size of the population does not change much. Which of the following is the best description of what life in this reserve is probably like for these anteaters?a. The anteaters have little or no difficulties obtaining food and raising offspring. ants. Their tongues are 24 inches long and covered with sticky saliva. Anteaters cannot open b. Adult anteaters compete for food and many young anteaters die. theirmouth, and do not have teeth. Even the stomachs of anteaters are unique: unlike most mammals,c. It is impossible to know without actually observing anteaters in the reserve.
Answers
Answer:
Adult anteaters compete for food and many young anteaters die
Explanation:
As there are not many predators and the number of ants is abundant, the population of anteaters should grow on a large scale, however, this is not what happens, since the size of the population is the same for twenty years. This shows that the anteater population itself is regulating the size of the population through internal disputes, where anteaters, due to the high birth rate, end up competing for food and shelter, causing the most young and inexperienced individuals to be killed.

The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete
Answers
Answer:
Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%Explanation:
Available data:
order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apartThe genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).
We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.
We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.
We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,
DCO prob = recombination frequency A-B x recombination frequency B-C
= 0.1 x 0.03 = 0.003 = 0.3%
DCO prob = 0.3%
According to this, we would expect to find
0.15% AbC0.15% aBcNow we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.
SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%
SCO prob A-B = 9.7%
we would expect to find
4.85% Abc4.85% aBCSCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%
SCO prob B-C = 2.7%
we would expect to find
1.35% ABc1.35% abCThe total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,
TCO= SCO A-B + SCO B-C + DCO
TCO prob = 9.7% + 2.7% + 0.3%
TCO = 12.7%

What if cellular respiration did not occur
Answers
Answer:
cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.
Explanation:
THE ANSWER IS FERMENTATION!!!!
Answer:
If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.
