What your cells have to help overcome a problem of high activation energy are called enzymes. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
Enzymes make things easier for your cells to work properly and help chemical reactions occur. There are hundreds of different kinds of enzymes in your cells, which all participate in different types of reactions. Enzymes can break molecules apart, build or add molecules, and even rearrange them.
In lowering the activation energy of a reaction, enzymes decrease the barrier to starting a reaction. It's important to note, however, that the change in energy remains the same between the start and end of a chemical reaction.
Rainforest plants have evolved waxy coatings on their leaves that allows moisture to drip off them. their roots are shallow to help them gather nutrients from the surface of the ground or directly from other plants.
Answer:
Yes, 75%
Explanation:
Since the first offspring produced between the ram and the ewe was black you can determine that both sheep have a recessive and dominant allele. Both of the parent's genotypes would be Ww, this is because they both have the white phenotype and they were able to produce a black offspring. Since both parents have a genotype of Ww the probability of a black offspring being produced is 25% and 75% for a white lamb.
Answer:
2:2
Explanation:
<em>The genotypic ratio of expected of their offspring would be 2</em><em>:2</em><em>.</em>
From the illustration, the genotype of the man with male pattern baldness is while the genotype of the woman without the baldness allele is .
Crossing the two genotypes in marriage:
x
Progeny:
<em>Hence, the genotypic ratio of the offspring becomes:</em>
2:2
