Answer:
d. He did not but instead proposed an erroneous evolutionary mechanism known today as inheritance of acquired characteristics.
Explanation:
Lamarck believed that organism changes as the environment change, and that those changes are passed to offspring ( inheritance of acquired characteristics). He also believed that if a certain structure isn't used by an organism it will gradually disappear through time.
According to Darwin's theory of evolution, natural selection is the main evolutionary mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).
Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.

A sex-linked trait is a trait that is carried by the X chromosomes in females but it is not expressed(the phenotype). Females are only carriers because they have two copies of the X chromosome [one of them carries the trait and the other does not]. Males who inherit one copy of the X chromosome often get the trait (because the trait is in either one copy or the other of the X chromosome) and express it while their Y chromosome would became recessive. Thus, only males express sex-linked traits such as hemophilia or color blindness
Answer: True
Explanation:
There is something called Skin flora. This refers to a group of microorganisms that reside on the skin. Staphlococcous aureus and Staphlococcous epidermidis are common examples. The Skin flora protects the skin from pathogenic organisms.
Answer:
Heterotrophs or consumers
Explanation:
This are organisms that cannot produce their own food. They rely on autotrophs ( plants or producers ) for food. Most of the times these are normally animals.
