Answer:
The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.
Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.
The ability of muscle to shorten forcibly when adequately stimulated is known as <u>contractility.</u>
Explanation:
- Contractility is defined as the ability of muscle cells to contract forcefully to bring about movement in body organs.
- The folding of arms are results of contractility of biceps and triceps.
- Contractility of cardiac muscle to regulate pumping of heart is again a result of contractility of myocardial muscle.
The umbra is the innermost and dark part of the shadow where like it’s created by any light source and is completely blocked by the occluding body. It’s a Latin term hope this helps man!
You have a population in hardy-Weinberg equilibrium for the m and n alleles. These alleles are codominant. Allele frequency of m is 0. 4. 0.48 is the frequency of heterozygotes in the population.
An allele frequency has been computed by dividing the total quantity of copies of each of the alleles at that specific genetic location in the population by the number of points of time the allele of interest has been observed in a population.
The frequency of each genotype is typically calculated by dividing the population's total count of individuals by the number of people who have that genotype.
