Answer:

Cnidarians represent a more complex level of organization than Porifera. They possess outer and inner tissue layers that sandwich a noncellular mesoglea. Cnidarians possess a well-formed digestive system and carry out extracellular digestion.

g100num [7]

If a heterozygous male with the genotype Ww is mated with a homozygous recessive female with the genotype ww, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are Ww, Ww, ww, and ww.

<h3>What is Genotype?</h3>

A genotype may be defined as the ultimate combination of the alleles of those genes which are selected for specific studies.

If a heterozygous male with the genotype Ww is mated with a homozygous dominant female with the genotype WW, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are WW, WW, Ww, and Ww.

Therefore, it is well described above.

Answer:

Deforestation negatively impacts the carbon cycle as trees play an important role in balancing the amount of carbon in the atmosphere.

Explanation:

Deforestation is one of the most damaging activities to the environment due to different reasons but mainly because it releases important amounts of carbon dioxide to the atmosphere due to the logging and burning of forests and also leads to the reduction of fauna populations because of habitat destruction.

In this case, cutting white and red pines and then setting a pine acreage on fire disrupts the carbon cycle because:

a) [As stated above] Trees play an important role in balancing the amount of carbon dioxide (CO2) in the atmosphere as there is less photosynthesis carried out by plants - important part of the carbon cycle.

b) When trees (wood) are burned, the carbon that was formerly stored is released into the atmosphere as CO2, leading to another disruption in the carbon cycle.

Answer:

PART B: My Own Masterpiece!

Activity 1: What are your true colors?

Use the given fictional genes of different colors to predict the phenotype ratio

and genotype ratio. Color each tile in the Punnett square corresponding to its

phenotype. An example is already given as your guide.
