Biology

Answer:

C.  sharp thorns

Explanation:

The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.

Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.

The gene for petal color in a flower has incomplete dominance, so that individuals with two A1 alleles (A1A1) are black, individ
Verdich [7]

Answer:

The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.

Explanation:

<u>Available data</u>:

  • The gene for petal color in a flower has incomplete dominance
  • Two A1 alleles (A1A1) express black color
  • Two A2 alleles (A2A2) express white color
  • One of each allele (A1A2) express mottled color

In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:

Parental)    A1A1    x    A1A1

Gametes)  A1   A1       A1   A1

Punnet Square)     A1         A1

                   A1    A1A1     A1A1

                   A1     A1A1     A1A1

F1 Phenotypes: 100% black flowers

F1 Genotype: 100% A1A1

There are 0% of probabilities of getting a mottled offspring.

What is a control value?
Inga [223]

Answer:

The value of control is a quantitative measure of the value of controlling the outcome of an uncertain variable. Decision analysis provides a means for calculating the value of both perfect and imperfect control. The former value, informally known as the value of wizardry, is an upper bound for the latter. Obtaining meaningful value-of-control measurements requires an awareness of important restrictions (concerning the nature of free will and the meaning of counterfactual statements) on the validity of this kind of analysis.
