The answer is D. learned behavior.
A change in behavior of an organism takes place due an experience is called learning. Animals learn behavior in many ways. On such way is given the question that anole lizard ate bright red butterfly instead small insects which are its normal food and became ill. Anole lizard learned through experience that bright red insects are not its food. Thus, a learned behavior is one that an organism develops by encountering experience.
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation. The next generation will have the things they will need to survive and the longer the generation goes the more fetchers they will have.
Answer:
No
Explanation:
This tool does not effect the environment because it doesn't contain any harmful chemicals that would interfere with the environment's well being.
Meiosis produces cells (germ cells or gametes) with only half the DNA, or chromosomes, as normal cells (somatic cells). This is called haploid or referred to as "n" number of chromosomes. Normal body cells have doubke that, called "2n," or diploid. For humans our n = 23, so germ cells (haploid) have only 23 chromosomes, while somatic (normal body) cells have "2n" or 46 chromosomes. It is important to only carry half the number of chromosomes or DNA (n), because it is going to combine with another half (n) when sperm meets egg during fertilization. This n + n = 2n restores the diploid number of chromosomes (DNA) in a zygote, the first cell of a future embryo, fetus, and new human being.
