Answer:
C
Explanation:
The cottontail population will experience rapid growth without predators but will eventually stabilize due to a lack of resources.

Answer:√√</h2>
...................................
The development of multi-cellular organisms begins from a single:::celled zygote, which undergoes rapid cell division to form the blastula. The rapid multiple rounds of cell division are termed cleavage.
<h3><u>Answer and explanation</u>;</h3>
- DNA ligase is a DNA-joining enzyme. If two pieces of DNA have matching ends, ligase can link them to form a single, unbroken molecule of DNA.
- DNA ligase usesATP as an energy source to catalyzes a reaction in which the phosphate group sticking off the 5’ end of one DNA strand is linked to the hydroxyl group sticking off the 3’ end of the other.
- The reaction produces an intact sugar-phosphate backbone of the DNA strand.
The correct answer is the law of segregation or the law of purity of gamete.
Meiosis results into the formation of gametes. The gametes are always pure for a particular trait because each gamete carries either the dominant or the recessive factor but not both as we find in F1 individuals. This follows the 'principle of segregation', the law proposed by Mendel. This law is also called 'law of purity of gametes'. The ratio 3:1 in F2 generation of a monohybrid cross suggests that alleles are segregated and the test cross confirmed it.
Answer: 49%
Explanation:
* long hair = P
* shirt hair = q using the Hardy-Weinberg equation for genotypic frequencies
* p^2 + 2pq + q^2 =1
*first use the equation to solve for the known value 18% hh
.18 = q^2
Square root .18 = q
So q = .42
* plug this allelic frequency in to p+q = 1
Which will give you the frequency of dominant alleles
1 - .45 = p So P = .58
Then just plug the P and q values found into the portion of the equation for heterozygous offspring.
2(.58)(.42)
Which is .49 or 49%
The entire population should be 33% homozygous dominant 49% heterozygous and 18% homozygous recessive.
