What is neutralism

Discuss aquatic,terrestrial and aborreal habitat in relation with adaptation and survival of organisms with these habitats 

12. Mapping of DNA allows scientist to compare the genes of organisms from the past and organisms present today, the evidence of evolution used is:

a. Fossil record

c. Analogous structures

b. Molecular Biology

d. Comparative Anatomy

14.How will you use biogeography as an evidence to infer evolutionary relationship?

a. Organisms living closer at each other and sharing the same niche are also closely related to each other.

b. The unique characteristics of the organisms living on a secluded area is indicative of their ancestry and speciation.

c. Biogeography revealed that organisms with similar developmental pattern even if found at different places might once live together before they were separated due to natural events or forces.

d. All of the above 

Ecosystems have the ability to "self-regulate". Explain the concept of self-regulation as it applies to ecosystems

In 5 points, Discuss aquatic, terrestrial and arboreal habitats in relation with adaptation and survival of organisms in these habitats

The increased use of wind turbines and solar collectors to generate electric power will...

Choices:

a- negatively affect ecosystems by increasing biodiversity

b- negatively alter the chemical composition of soil and water

c- reduce the amount of pollution that comes from the burning of fossil fuels

d- increase oil consumption for business and industry

• List the analytic and synthetic character of biological community explain in one or two lines the information provided by each character about the community

(a)   Some GM crops that are available to farmers are resistant to herbicides (weedkillers). Other GM crops are resistant to diseases caused by viruses and to damage by insects. Some people are for the use of GM crops because they may be beneficial to ecosystems. Some people are against the use of GM crops because they could harm ecosystems. Discuss these opinions for and against the use of GM crops.
