Answer:
The mitochondria is the powerhouse of the cell
Answer:
parasitism
Explanation:
In parasitism, one species(host) is harmed and another species(parasite) is benefitted.
Answer:
In the resulting offspring the correct proportions are for the genotype 1:1 and for the phenotype 1:1 (first option).
Explanation:
According to Mendel's Laws, the product of the cross between a heterozygous individual and a homozygous recessive for a character will always be a hybrid or recessive offspring as the Punnett square shows on image.
For the character -tall and short- of the pea plant:
Alleles t t
T Tt Tt
t tt tt
<u>For the genotype</u>: probabilities that in the offspring there are hybrid individuals with genotype Tt is 50% and recessive tt 50% .
<u>For the phenotype</u>: the probabilities of tall plants in the offspring are 50%, and 50% short plants.
A 50:50 ratio, for genotype and phenotype, is equivalent to saying that both phenotypic and genotypic ratio is 1:1.

Answer:
Natural selection produces changes most quickly in species with short reproductive cycles.
Explanation:
Natural selection implies a process of changes in the genome of species, induced by their environmental conditions, which allow them to survive. The processes of natural selection usually manifest themselves after long periods of time and are synonymous with adaptive evolution.
Since natural selection depends on the changes observable in successive generations within a species,<u> in organisms with short reproductive cycles the changes promoted by natural selection could be observed most quickly</u>.
