Organisms adapt to their changing environment. When there is some pressure in the environment (for example, increased competition for food), then species with the most advantageous adaptations will survive. Because environments change pretty frequently, the organisms living there must cope with this change. This leads to ever changing and evolving species and increased biodiversity. Lastly, a high level of biodiversity leads to a healthy ecosystem because of the vast variety of organisms in that space. Many species allows niches to overlap and therefore no one organism occupies one niche.
Mycology is the study of fungi.

I took this class, but if I remember so it is true
Answer:
Concentration gradient.
Explanation:
Diffusion may be defined as the process of the movement of solute particles down the concentration gradient. This process does not require the expenditure of energy.
The main driving force in diffusion is the concentration gradient. The molecules generally move from its region of the higher concentration towards the region its lower concentration.
Thus, the correct answer is option (3).
Answer:
25%
Explanation:
From the description;
The parents: half shaded circle and square = heterozygous parents
The offspring:
unshaded square = homozygous normal
half shaded circle = heterozygous normal
half shaded circle = heterozygous normal
completely shaded square = affected (homozygous abnormal)
The unshaded and half shaded offspring are normal and do not have sickle cell anemia. The completely shaded square represents a male offspring with sickle cell anemia.
<em>Out of 4 offspring, 1 is affected for sickle cell anemia. Hence the percentage of the offspring that have sickle cell anemia is 25%.</em>
