Answer:
Tall(Tt), Tall(Tt), Short(tt), Short(tt), 50% Tall stems, 50% Short stems
Explanation:
If the Tall plant is heterozygous it means that there is a dominant allele for Tall (T), but the short (t) allele is still present. Therefore the genotype for this parent would be Tt. Homozygous means that there are two of the same allele, so in this case Homozygous recessive would be tt.The probability of offspring from these two parents can be determined from a Punnet Square or the Foil method ( which I have shown further ). Equation: Tt*tt
First- First Terms of each parent; T*t
Outer- First Term of first parent and Last Term of second parent; T*t
Inner- Last Term of first parent and First Term of second parent; t*t
Last- Last Term of first parent and Last Term of second parent; t*t

Answer:
a) Humans depend upon other organisms for food and oxygen
Explanation:
Biodiversity refers to the richness in the species of organisms on Earth i.e the variety of biological organisms on the Earth. The importance of biodiversity cannot be overemphasized because of our dependence on the sustainability of biodiversity in our ecosystems.
The loss of biodiversity, which is becoming rampant by the day, is a major concern to us because we humans depend upon other organisms for food and oxygen. Humans are strictly heterotrophic and hence are reliant on variety of organisms for food. Plants also release oxygen gas via their photosynthetic process, which is key to our survival as a population.
