Answer:

taking the pretest

Explanation:

A one-group pretest–posttest design is a type of research design generally used in behavioral research aimed at estimating the treatment effects on the sample. In this experimental design, the target group of participants is first pre-tested on the dependent variable and, subsequently, post-tested after the administration of a treatment. In consequence, the participants of the target group receive the same treatment and assessment. The problem of testing effects indicates that testing may become a problem when the pretest may change participant's behavior. ​When there are statistically significant differences between the pretest and posttest data, it is possible to support the working hypothesis.

Would white fur color be an evolutionary advantage if the arctic circle began to resemble a temperate forest biome?
Firdavs [7]

Answer:

White fur is only an evolutionary advantage if the creature can hide in snow.

If you live in a temperate forest biome and want to hide from enemies, you wouldn't want fur that sticks out brightly against the dark forest.

Just like, if you lived in a snowy biome, you wouldn't want black fur that would stick out against all the snow.

So no, white fur is not an evolutionary advantage in a temperate forest biome

Hope this helps!

5. The F2 generation of a cross between a parental tall and a parental short pea plant is 298 tall plants and 102 short plants.
Vadim26 [7]

Answer:

The answer is XX.

Explanation:

Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous  to have the short phenotype which means it needs to have the genotype xx or Xx.

The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.
