At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

How does diversity in traits arise over generations? How can we determine the probability that an organism's expressed version of a trait will be passed on to its offspring?
Answers
Answer:
Diversity in traits arise over generations through mutation which cause evolution and speciation. We can determine the probability that an organism's expressed version of a trait will be passed onto its offspring through Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium helps us understand and know genotype and allele frequencies.
Through mutation, which leads to evolution and speciation, diversity in features develops over generations.
What is diversity?The variety of human distinctions that make up diversity includes, but is not limited to, racial or ethnic origin, gender, gender orientation, age, socioeconomic class, physical ability or traits, and political ideas.
Over generations, diversity in traits emerges through mutation, which causes evolution and speciation.
We can calculate the probability that an organism's expressed version of a trait will be passed on to its offspring using the Hardy-Weinberg equilibrium.
The Hardy-Weinberg equilibrium is used to explain genotype and allele frequencies.
Thus, this way, we can determine the probability that an organism's expressed version of a trait will be passed on to its offspring.

As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting from this soil called?
Answers
Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.

B. False, it should read, "Some people who carry a faulty allele develop a disease, some
are carriers."
C. True
D. False, it should read, "No one who carries a faulty allele becomes a carrier."
Answers
The statement "Everyone who carries a faulty allele develops a disease" is absolutely false. This is because some people who carry a faulty allele develop a disease, some are carriers. Thus, the correct option is B.
What is an Allele?An allele may be defined as one or two or more alternative forms of a gene. An individual always inherits two alleles, one from each parent that shows characteristic traits for any given genomic location where such variation exists.
If the two alleles are the same, the individual is homozygous for that allele. While, if the two alleles are non-identical, the individual is heterozygous for that allele.
It is not possible that everyone who carries a faulty allele develops a disease because it depends on the expression of the disease, whether it is dominant or recessive, sexual or autosomal, etc.
Depending on the same principle, some are affected by the disease when both alleles have the same traits while some are carriers.
Therefore, the correct option for this question is B.

The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answers
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1

Answers
Answer:
a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized.
Explanation:
Metabolic acidosis is an electrolyte disorder characterized by a pH of less than 7.40 and low bicarbonate (HCO3) levels in the blood. This disease may be due to 1-an increasing acid production, 2-loss of HCO3 (which acts as an acid buffer agent), and 3- by a decreasing ability of the kidneys to maintain normal acid levels. The kidneys contribute to maintaining the acid–base balance by excreting hydrogen ions (H+) into the urine and absorbing HCO3 from the urine. In metabolic acidosis, kidneys are unable to remove enough acid and conserve sodium ions (Na+), which is normally done by excreting ammonia in the urine.

B. It is a reflex response that causes various muscles to contract in order to move away from the object.

Answer:
B. It is a reflex response that causes various muscles to contract in order to move away from the object.
Explanation:
I just took the Test
It is a reflex response that causes various muscles to contract in order to move away from the object. Therefore, option (B) is correct.
What is reflex response?A reflex response is an automatic, involuntary response to a stimulus that does not involve the conscious part of the brain. In this case, the reflex response causes various muscles to contract in order to move away from the sharp object, which helps to minimize further injury. Reflexes are a protective mechanism that can operate without the need for conscious control or decision making.
The reflex response described in this scenario is not a learned response, a conditioned response, or a voluntary response. It is an innate, automatic response that occurs in response to a specific stimulus, and it occurs in both infants and adults.
