Ksju [112]2 years ago
8 0

Answer:

The options to this question are unclear but the answer is: Hh, Hh, hh, hh i.e Hh (50%), hh (50%).

Explanation:

This question involves a single Gene coding for the possession or not of Huntington's disease in humans. The disease is said to be an autosomal recessive condition i.e. it only happens in a recessive state (hh).

According to this question, when a female with Huntington disease (hh) mates with a male that is heterozygous (Hh) for the Huntington trait, the following gametes will be produced by each parent.

hh - h and h

Hh - H and h

Using these gametes in a punnet square (see attached image), the following genotypic combination of offsprings will be produced.

Hh, Hh, hh and hh

Hh = 50%

hh = 50%

If we removed the decomposers from this food web, how would it affect the balance of the ecosystem? A.)There would be an increas
Ymorist [56]

Answer:

A

Explanation:

The dead matter from organisms such as plants and animals that die need to be recycled so the nutrients in the matter are released and used up by other organisms. This is how sustainability is achieved in ecosystems through a cyclical nature of nutrients flow. Decomposition of the dead matter is done by decomposers such as fungi and bacteria. Without them, the dead matter would accumulate while the soil would lack nutrients for plants to grow and for other bacteria to utilize for energy. This would affect the rest of the food chain/web causing the ecosystem to collapse.
