Answer:
The organisms have a common ancestor
Explanation:
Homologues structyres conclude that organisms of different species share structures, making them all have some sort of common ancestor
It would be 100%. As you can see in my punnet square, there are no boxes with ww, which means that ll of the flies would have curled wings. (this is because you have to have two recessive genes for that gene to show)
So it would be
A. 100%
Answer:
The correct answer is option C, that is, increase the concentration of the enzyme.
Explanation:
Biological molecules or proteins that enhance the rate of a chemical reaction taking place within the cell are known as enzymes. These proteins play an essential part in the proper functioning of the body, as they help in the process of metabolism and digestion.
In the given case, if the enzyme gets saturated with the substrate, and is working at optimum pH and temperature, then to enhance the rate of the reaction the only thing that can be done is to enhance the concentration of the enzyme. However, further stimulation of some of the enzymes can be done with the addition of allosteric activators in the reaction, otherwise, enhancing the concentration of the enzyme is the only way.
The answer I came up with is Echinoderms and Chordates.
Happy studying!
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
<u>Bb X Bb cross
</u>
alleles B b
B BB Bb
b Bb bb
Where the result is:
<u>Genotypes</u>:
<u>Phenotypes</u>:
- Brown feathers, 75%
- Red feathers, 25%.
In this case, the probability of having brown or red feathers is 3:1.
