Answer:
Red Blood Cell lacks a nucleus, it would be unable to carry oxygen efficiently.
Explanation:
The absence of a nucleus is an adaptation of the red blood cell for its role. This allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its own distinctive bivalve shape, which promotes diffusion.
Answer is;
The animal population in the environment will increase.
This is because the grass is the main producer in a habitat. Its plentifulness directly influences that of the consumers up the food web. Increase in grass population means reduced competition for primary consumers and their population will therefore increase. This will also reduce competition for secondary consumers and tertiary consumers up the chain.

The two major contribution in forensic science made by Hans Gross are the following:
1. He is one of the founders of criminalistics for his research on the subject and the release of his book criminal investigation in 1891. The book was the first of its kind to be published which helps establish the science of forensics especially in terms of a cross transfer evidence from criminal to the victim.
2. He detailed the assistance that investigators could expect from the fields of microscopy, chemistry, physics, mineralogy, zoology, botany, anthropometry and fingerprinting. He later introduces the forensic journal, which improves methods of scientific crime investigation.
