If your power could have been harnessed and the energy converted to electricity, how many 100-w bulbs could you have kept burning during your climb?
When the power is harnessed and the energy converted to electricity, the person could have climbed using only one 100-W light bulb.
What is power?Power is defined in physics as the amount of energy transferred or converted per unit time. The watt is the unit of power in the International System of Units, equal to one joule per second.
It can be defined as the rate at which work is completed in a given amount of time. Watt (W) is the SI unit of power, which is joules per second (J/s).
And, because our estimate is very rough, we can say that the person's power output is comparable to the power output of a 100 W light bulb. Let's say that the mass is 80kgbabs it takes 30 seconds to climb 5 meters of stair, the energy will be:
= mgh
= 80 × 9.81 × 5
= 3924J
Power will be:
= 3924 / 30
= 130W
Based on the results obtained, we can conclude that the person's power output is comparable to the power output of one 100-W light bulb, and that the person could have continued to burn only one 100-W light bulb during the climb.

When a man who is a carrier for sickle cell anemia mates with a woman who is also a carrier for sickle cell anemia then the probability that the couple will have a child who is homozygous for the sickle cell anemia allele and thereby affected by the disease is 25%.
What is sickle cell anemia?Sickle cells that block the flow of blood to organs deprive the affected organs of both blood and oxygen. In sickle cell anemia, blood is chronically low in oxygen and this lack of oxygen-rich blood damage nerves and organs including kidneys, liver and spleen, and can be fatal.
There is a 25% chance that a child, regardless of sex, will have the disease if man and woman both are carriers of disease. Since, sickle cell anemia is an autosomal recessive trait, therefore female and male offspring are affected equally.

periods in which new species appear relatively quickly are associated with the theory of . a. punctuated equilibrium b. reproductive isolation c. microevolution d. mutation
New species appear relatively quickly are associated with the theory of . (a) punctuated equilibrium. So option (a) is the correct answer.
A pattern of rapid evolutionary change followed by long periods of stagnation is a pattern explained by an interrupted equilibrium. Punctuation equilibrium states show that organisms do not change much as they appear in the fossil record.
Interrupted equilibrium predicts that many species evolutionary changes occur on short time scales associated with speciation events.
An intermittent equilibrium occurs as genetic variation passes more rapidly, increasing the rate of evolution and speciation. Tyrannosaurus fossils and mollusks species from the Turkana Basin are examples of intermittent equilibrium.

6. Why do you think that changing the temperature changes the rate of
photosynthesis?
The quantity of enzyme-substrate collisions limits the pace of photosynthesis at low temperatures. The rate of photosynthesis rises as a function of temperature because there are more collisions as a result.
Why does the rate of photosynthesis first rise with temperature and then fall?Photosynthesis is a specialized enzyme-based process. The enzymes involved in this process operate best at a certain temperature.
Enzymes denature if the temperature rises over the maximum optimal temperature, which slows the rate of photosynthesis.
The rate of photosynthesis grows as the temperature rises, much as other chemical processes.
Enzymes, which regulate photosynthesis, get denatured at high temperatures. The rate of photosynthesis therefore reaches its peak.

The frequency of the recessive allele (gg) in a population where 25% individuals exhibit albinism is 0.5.
According to Hardy weinberg principle, the frequencies of the genotypes can be determined by an equation: [tex](p+q)^{2}[/tex] = [tex]p^{2}[/tex] + 2pq + [tex]q^{2}[/tex], where [tex]p^{2}[/tex] represents the frequency of homozygous dominant allele and [tex]q^{2}[/tex] represents frequency of homozygous recessive alleles. As albinism is caused by recessive alleles ([tex]q^{2}[/tex]), the frequency would be half of the total frquency, that is 0.5 of 1, because p + q = 1.
Making one of the many proteins involved in the manufacture of melanin is controlled by a number of genes. Melanocytes, which are cells present in your skin, hair, and eyes, are responsible for producing melanin. A change in one of these genes leads to albinism.

When a mutation first appears, the selection would occur against it as it lowers the inclusive fitness.
A technique for gauging the effectiveness of evolution is inclusive fitness. It is the capacity of an individual to pass on genes, including those shared with relatives, to the following generation.
However, advantageous mutations will proliferate and boost the population's overall fitness. They produce unique protein variations that help organisms adapt to changes in their environment. Most of the time, natural selection boosts evolutionary fitness and causes organisms to adapt to their environments. Thus, in this case the selection would be against the mutation.
Positive mutations are essential for evolution to occur. They increase an organism's likelihood of surviving or procreating, so they are likely to spread over time and become more widespread.
