Answer: 1. principle of uniformitarianism, 2. worms have no hard parts

The principle of uniformitarianism suggests that the geological processes occurring in the past were in the same manner and with the same intensity that as they occur in the present. Therefore, the phrase "The present is the key to the past" rephrases the principle of uniformitarianism.

A worm cannot be fossilized because it does not possess hard parts like bones, shells, teeth as other organisms exhibit. They have tube like body with soft tissues, which gets completely decomposed by microbes after death.

In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t
Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² +  2pq+ q²  = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = \sqrt{0.35} = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.
