Answer:

A). Anaerobic Exercise.

Explanation:

Anaerobic Exercise is characterized as the exercise that aims to break down glucose without making use of oxygen. Such exercise involves short, quick, and intense bursts of energy with maximum efforts. This leads to the body needing immediate energy(except oxygen) to fuel itself that eventually leads to the break down of glucose. This exercise primarily aims to 'build the mass of the muscles or enhance the muscular strength, through short and intense workouts involving jumping, sprinting, running, cycling, etc. Therefore, option A is the correct answer.

Answer:

A). Hypoxia.

Explanation:

Hypoxia is characterized as the condition in which tissues are deprived of an adequate supply of oxygen. As per this definition, hypoxia would be the process that is most likely to occur in the plant's leaves when it is revealed to a minimum level of 1 or 2% of oxygen. The lack of oxygen in such states reaches the tissues. One of the advanced stages of this process is 'anoxia; where there is a complete absence of 'oxygen' that enhances the ecological stress. Thus, option A is the correct answer.

Answer:

Parasitism.

Explanation:

The relationship between a tomato plant and the hornworm caterpillar is parasitism because parasitism is a type of symbiotic relationship in which one organism get benefits and the other get harmed. We know that hornworm caterpillar feed on leaves and destroy the tomato crop. So it gets nutrients from tomato plant and the tomato plant is negatively affected. The input of this system is the vegetative part of tomato plant while the output is the conversion of hornworm caterpillar into a moth.

Explanation:

Sodium intake is important to health and most importantly, it is important to the heart. But excess sodium can lead to serious health issues. Therefore, the intake of sodium should be limited.

As per American Heart Association, an average American consumes more than 3400 mg sodium per day in their food. But the consumption must be limited to 2300 mg.

I am very much surprised to know that I consumed a lot more than this limit of sodium in my daily diet. I take up nearly 200 % of sodium intake. I am surprised by this and very much worried. If I continue to take sodium like this, it will have ill affects on my heart. So, I need to reduce my intake to less than 2300 mg of sodium a day. And also I need to do some cardiovascular exercise regularly.

Explanation:

Answer:

Scientists used the scientific method of investigation to test this phenomenon. The scientific method consists of these steps:

Make observations: Scientists observed that nerve damage causes severe pain. Scientists knew bone marrow cells seemed to decrease nerve pain, but the reason was unknown.

Ask questions and construct the hypothesis: Would injecting bone marrow cells into the spinal cord decrease pain?

Test the hypothesis: Injected bone marrow cells into the spinal cord of mice that had nerve damage. Observed changes in the cells, and monitored the pain levels in the mice.

Analyze the results and make a conclusion: Determined that the pain decreased because the bone marrow cells released a pain-relieving protein that helps damaged cells.

Test and modify: Make a plan to repeat the test in humans.

Explanation:

Answer:

Master genes tend to be conserved.

Explanation:

Master genes, which are the genes in the DNA that control major development processes such as the development of the skeleton, the organs etc and the production of the necessary proteins.

Since they take on such an important role, they don't really change much. Master genes that affect development tend to be highly conserved so embryonic development can show similar patterns.

Answer:

a. Only one of the two populations is in Hardy-Weinberg equilibrium

b. The Population of City cats is not in Hardy-Weinberg equilibrium because  the proportion of dominant and recessive genes have been forced to change by outside force of migration, selection and mutation

Explanation:

By the Hardy-Weinberg Law, we have;

p² + 2·p·q + q² = 1

p + q = 1

p = Dominant allele frequency within the population

q = Recessive allele frequency within the population

p² = Percentage of individuals that are h o m o zygous dominant

q² = Percentage of individuals that are h o m o zygous recessive

2· p · q = Heterozygous individuals percentage  

Therefore, for the country cats, we have;

p² = 0.49

p = √0.49 = 0.7

q² = 0.09

q = √0.09 = 0.3

2×p×q = 2×0.7×0.3 = 0.42 = The value given in the table

Which shows that the country cats are in Hardy-Weinberg equilibrium

For the city cats, we have;

p² = 0.52

p = √0.52 = √(13)/5

q² = 0.03

q = √0.03 = √3/10

2×p×q = 2×√(13)/5×√3/10 = √(39)/25 ≠ 0.45 which is the value given in the table

Which shows that the City cats is not in Hardy-Weinberg equilibrium

Therefore, only one of the two populations is in Hardy-Weinberg equilibrium

b. The Population of City cats is not in Hardy-Weinberg equilibrium because  the proportion of dominant and recessive genes have been forced to change by outside force of migration, selection and mutation.

Following the Hardy-Weinberg theory, we can say that the country cats population is in equilibrium, while the City cats population is not. This is probably due to the action of evolutive forces.

The Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,

The genotypic frequencies after one generation are

If a population is in H-W equilibrium, it gets the same allelic and genotypic frequencies generation after generation.

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

We are given the genotypic frequencies of each population.

Now, we need to say if these populations are in H-W equilibrium, and if not, why?

So let us analyze each population separately.

We have the following genotypic frequencies, F(xx).

Now, we need to get the allelic frequencies, p and q.

To do it, we will add half the heter0zyg0us frequency to each of the h0m0zyg0us frequencies.

        p = 0.7 ⇒ Frequency of the dominant allele

        q = 0.3 ⇒ Frequency of the recessive allele

Now, if this population is in H-W equilibrium, it will get the same allelic and genotypic frequencies generations after generation.

So now, we will get the genotypic frequencies (p², 2pq, and q²) of the following generation.

The given genotypic frequencies in one generation are equal to the calculated genotypic frequencies in the next generation.

We can conclude this country's cats population is in Hardy-Weinberg equilibrium. No evolutive events are going on.

We have the following genotypic frequencies, F(xx).

Now, we need to get the allelic frequencies by adding half the heter0zyg0us frequency to each of the h0m0zyg0us frequencies.

        p = 0.745 ⇒ Frequency of the dominant allele

        q = 0.255 ⇒ Frequency of the recessive allele

Now, if this population is in H-W equilibrium, it will get the same allelic and genotypic frequencies generations after generation.

So now, we will get the genotypic frequencies (p², 2pq, and q²) of the following generation.

The given genotypic frequencies in one generation differ from the calculated genotypic frequencies in the next generation.

          Generation 1           Generation 2

p²               0.52                         0.555

2pq            0.45                          0.379  

q²              0.03                          0.065  

We can conclude that this city's cats population is not in Hardy-Weinberg equilibrium.

Probably some evolutive events are going on.

The evolutive forces affecting the H-W equilibrium are natural selection, genetic drift, and genetic flow. The mating system might also affect the equilibrium in this population.
