In pea plants, smooth (S) peas are dominant over wrinkled (s) peas in the single gene controlling pea texture. A plant with smoo
OlgaM077 [116]

Answer:

Ss and ss

Explanation:

<em>Since the smooth trait (S) is dominant over the wrinkle trait (s), the genotype of the wrinkled pea parent is definitely </em><em>ss</em><em>.</em>

<em>Also, some of the progeny had wrinkled pea texture (ss). Each of the 2 wrinkled alleles must have been donated by each of the parent. It thus means that the smooth pea parent is heterozygous for the trait (</em><em>Ss</em><em>).</em>

Now, let us look at a cross between the two parents;

  Ss   x   ss

Progeny: Ss, Ss, ss, ss.

Phenotypically, 50% of the progeny are smooth peas while 50% are wrinkled.

Looking at the population of each of the phenotype resulting from the cross. 252:247 is approximately a 50:50 ratio.

Hence, the genotypes of the two parents are Ss and ss.

Zinaida [17]
There are choices for this question namely:

a. What is your name and where do you live?
b. How much poison did you swallow?
c. How long have you been feeling this way?
<span>d. What have you recently had to eat or drink?
</span>
The correct answer is "what have you recently had to eat or drink". This will confirm the suspicion by first ruling out potential reactive foods or drinks that may have caused a similar reaction (i.e. allergic reactions). If that is ruled out, then the probing about the history of intake of poison will come next in the interview.

Explain what would occur between Oceanic crust and continental crust at the subduction plate boundary. (O.C. =more dense)
Reika [66]

Answer:

Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. (Sometimes, oceanic crust may grow so old and that dense that it collapses and spontaneously forms a subduction zone, scientists think.)

Water has special characteristics because of the nature of hydrogen bonds what are they?
Amanda [17]

Water has special characteristics because liquid water is denser than ice and ice floats on top of liquid water​.

Answer: Option A & D

<u>Explanation:</u>

A water molecule is formed by the covalent bonding between two atoms of Hydrogen atom with one atom of Oxygen. In water, the Hydrogen bonds are the one that keeps the water molecule intact.  

When the water molecule freezes the bonding becomes weak as they are separated and set apart which makes the liquid water denser than ice. Normally a substance floats if it is less dense. Ice floats because it is less dense than water.
