The answer is: Organisms will not pass acquired physical traits to the next generation.
In his theory, Lamarck proposed how species adapted to the changed environment by passing down <span>acquired physical traits to the next generation. But, after Charles Darwin published his theory of evolution, Lamarck's theory was rejected. Now, it is known that acquired physical traits could not be inherited and epigenetics is a good proof for that.</span>
Answer and Explanation:
Mutation:
It is the sudden variation that occurs in the sequence of our DNA either due to factors related to environment or mistakenly. These are inheritable changes in our genes.
Effects:
a. It results in the ability of an organism to adapt to the environmental variations.
b. It can also cause disorders and diseases in an organism.
c. It results in the evolution of organisms.
d. It also results in the variation in an organisms' phenotype.
d. It helps to carry out scientific research.
Patterns of Inheritance:
The inheritance in mutation only occurs when it is in germ cells which leads to the production of gametes and this mutation is known as germ line mutation.
Data analysis:
As only few cells are effected mostly in mutation it can not be detected.
The correct answer is c. smoke stacks.
Smoke stacks are chimneys or funnel shaped structures which emit smoke from a factory, vehicles and industrial set ups. Smoke stacks mostly discharge carbon dioxide and water vapor and oxides of nitrogen into the atmosphere. The exhaust released from smoke stacks cause air pollution. Air pollution can cause ailments like asthma and cancer. Thus, smoke stacks are not a source of water pollution.
Answer: A. Autotrophs supply food for the heterotrophs.
Explanation: A deer is a heterotroph and a plant is a autotroph. Examples of heterotrophs are animals and humans, and examples of autotrophs would be plants and algae. Therefore, because a deer consumes plants that means that autotrophs supply food for the heterotrophs. And by the way I did the exam myself and got this answer correct!
