organisms must be capable of avoiding, and/or defending against, various types of environmental threats to survive. respond to each of the following:

a) describe what mimicry is and how it can be used as a defense against predation. include two examples in your answer.

b) describe one way in which plants can protect themselves against predation.

c) explain two types of nonspecific defenses that prevent the entry and/or establishment of a pathogen in the human body and give a specific example of each.

A) Mimicry is when an organism resembles another organism or an object. This method can be used to avoid predators. The prey can conceal itself and mimic the surroundings, protective mimicry. For example: the stick insect resembles a twig. Another way prey can protect itself against predators is to mimic a poisonous organism, warning mimicry. For example: the king snake resembles the highly poisonous coral snake in order to ward off predators.

B) Plants can develop thorns or inflict poison on predators. For example: stinging nettles release a mixture of toxins that cause pain when touched.

C) A barrier for pathogens would be skin and the process of coughing or sneezing. Which releases most bacteria and pathogens from the body.

I hope this helps, happy to help a fellow BTS Army

Explanation:

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
