Answer:
687millimoles
Explanation:
To calculate the amount of K reabsorbed in the kidney of an individual, we say:
Amount reabsorbed = Amount filtered + Amount secreted - Amount excreted
Based on the provided information,the respective amount of K is:
Amount filtered = 720 millimoles
Amount secreted = 42 millimoles
Amount excreted = 75 millimoles
Hence,
Amount reabsorbed = 720 + 42 - 75
Amount reabsorbed = 762 - 75
Amount of K reabsorbed = 687millimoles
Consider a scenario where a person eats a cupcake composed of glucose molecules. The person has digested the cupcake, and the glucose has been absorbed into the bloodstream. Based on this information and your knowledge about biology, select true or false for each of the following statements.
a. Some of the energy stored in glucose will eventually be transformed into heat.
b. Carbon atoms from glucose could be exhaled by the person as carbon dioxide.
c. Carbon atoms from glucose could later be found in a plant cell.
d. Carbon atoms from glucose could be converted into oxygen during metabolism.
Answer: a.b.c-true.
d-false.
a. Some of the energy stored in glucose will eventually be transformed into heat.
This is through the process of Glycolysis (and Krebs's cycle )where the Carbon atoms in the glucose(substrate level phosphorylation) undergo metabolism with the liberation of ATPs as heat during metabolisms. The glucose serves as the substrate for the generation of heat.However,largest amount of ATP's is expended as heat during oxidative phosphorylation,due to the glucose used as substrate in preceding stages of glycolysis and Kreb Cycle.
b. Carbon atoms from glucose could be exhaled by the person as carbon dioxide.
Yes, this is through glycoylsis and kreb's Cycle where CO2 is given off as during metabolisms as one compound change from one form to another.E.g from Citric acid(6C) to Succinate(5C),some Carbon atoms are lost as C02. Like during glycolysis.
C. Carbon atoms from glucose could later be found in a plant cell.Yes this is because the CO2 expired by human could be trapped by green plants and react with water in the presence of sunlight trapped by chlorophyll to form carbohydrate in plants.This is photosynthesis.
Explanation:
Carbon can't not be converted to oxygen,big FALSE.

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage.
The mutation of sickle cell anemia. Red blood cells.
Which type of mutation causes sickle cell anemia?
silent

Which statement best describes cancer cells?
A.cells that go through mitosis successfully
B.cells that continue to replicated even when not needed and does not stop
C.cells that move to G0,the resting phase
D.cells in hypotonic, solution to burst
Answer:
B!
Explanation:
Cancer is a essentially a mistake in a cell's DNA. This is very gradual, and takes a while. The immune system deals with most of them, but some slip out of reach and continue to mutate until they grow into tumors, or large pockets of cancer cells. Since their genetic code is very messed up at this point they have no limitations on growth.

A fish of genotype a/a ; B/b is crossed with a fish whose genotype is A/a ; B/b. What proportion of the progeny will be heterozygous for at least one of the genes
Answer:
Proportion of heterezygous progeny = 3/4
Explanation:
According to Mendel's law of independent assortment which states that the alleles of two (or more) different genes get sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele received for another gene.
Gametes produced by the fishes assuming independent assortment:
Fish 1 = aB, ab, aB, ab
Fish 2 = AB, Ab, aB, ab
Progeny from cross:
aBAB, aBAb, aBaB, aBab
abAB, abAb, abaB, abab
aBAB, aBAb, aBaB, aBab
abAB, abAb, abaB, abab
Proportion of heterezygous progeny = 12/16 = 3/4
In modern taxonomy, species are the most

Species are the most specific in modern taxonomy.
Taxonomy is defined as the scientific method of classifying, identifying and naming living organisms.
In the hierarchy of living organisms, the largest group of organisms is the Kingdom. This is followed by:
Phylum
Class
Order
Family
Genus and
Species (which is lowest in hierarchy).
The species is the smallest unit of classification.
It is the most specific because the individuals within a species are:
Identical in appearance,Closely related and Can mate with one another to produce fertile offspring.Therefore, species are the most specific in modern taxonomy.

The atmosphere exerts a force on earth. Why does yhe atmosphere exert pressure on earth?
Answer:
The atmospheric molecules have energy because they have a quantifiable temperature. It vibrates and circulates, and bumps into other gas molecules. Most of them are elastic, which means that the molecules bounce off more than they stick together. The "bump" is a strength. It becomes pressure when applied over an area, such as your skin or earth's surface.
Explanation:
How much is the pressure of the atmosphere?
Pressures are determined by height (mostly by the volume of water vapor), temperature, and weather. The average air pressure, however, is 14.7 pounds per square inch, 29.92, or 1.01 to 105 paschal in regular conditions at the marine level. At 5 km altitude, atmospheric pressure is just about 50%. (about 3.1 miles).
Why is the Earth's surface under pressure so much higher? It's because the weight of all the air at that location really is measured. There's not much air around you to press down while you are high in the atmosphere. The whole atmosphere is heaped above you on the surface of the Earth. While the gas molecules are extremely light and distant, they are many!

Explanation:
Answer:
Invasive species
Explanation:
An invasive species is an animal imported from another country. For example: the Giant African Snail. Hence their name, the Giant African Snail came from Africa. They first came into Florida as pets, and were then released into the wild. Since then, they have spread across the state. These snails eat plants voraciously, damaging crops and competing with local wildlife. They will also eat stucco, wood, and plaster, causing thousands of dollars in damage.

A eukaryotic cell has 6 chromosomes, explain what you would get at the end meiosis.
Answer:
If a eukaryotic cell has 6 chromosomes, the end result after meiosis is two daughter cells with 3 chromosomes each.
Explanation:
Meiosis is the process of cell division by which sex cells or gametes are formed. It is a mechanism of reductive division, since the chromosomal charge of a eukaryotic cell —diploid— is reduced by half, that is, haploid cells are obtained.
A diploid eukaryotic cell with 3 pairs (6) of chromosomes, after meiosis produces two haploid daughter cells, with 3 chromosomes each.
This process of reductional division, where the gametes are obtained, aims to ensure that when the gametes of each parent join together they form a diploid cell, the zygote.
