Answer:

B The progeny of a cross between two different lizard species fail to develop properly.

Explanation:

Two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

  1. Habitat isolation: Two species occupy entirely different and distant habitats.
  2. Temporal isolation: Two species  procreate at different times of the year.
  3. Behavioral isolation: Two species exhibit different mating behaviors.
  4. Gametic isolation: The gametes of the two species cannot fertilize.
  5. Mechanical isolation

Option B states an example of post-zygotic barriers. The two different species of lizards have mated, but their progeny will either face severe developmental issues and/or be sterile.

Answer:

Option D = 3.4 g/mL

Explanation:

Given data:

Volume of water = 21.2 mL

Volume of water + object = 27.8 mL

Mass of object = 22.4 g

Density of object = ?

Solution:

First of all we will calculate the volume of object.

Volume of object = Volume of water+ object - volume of water

Volume of object = 27.8 mL - 21.2 mL

Volume of object = 6.6 mL

Density of object:

d = m/v

d = 22.4 g/ 6.6 mL

d = 3.4 g/mL

Why the children in a family may have different genotype and phenotype than predicted by the punnet squre
Vadim26 [7]

Answer: Probability/mutations

Explanation: A punnett square predicts the probability that a child or the offspring will receive specific genes or look a certain way. The genes with the highest percentage or usually the ones that show, but sometimes recessive genes are the ones that show through, which may be what you mean by a different genotype/phenotype being different that what was predicted by the punnett square.

a mutation may also occur that messes up all of this.
