Question

NEED HELP WITH TWO QUESTIONS! WILL FAN AND MEDAL!

Questions 1) Organisms use a variety of mechanisms and behaviors to defend against environmental threats, predation, and disease. Respond to each of the following:
1. Discuss how the human immune system responds to an initial pathogenic exposure and how this initial exposure can lead to a quicker response following a second exposure to the same pathogen.
2. Discuss two types of animal behaviors that help defend against predation. Include specific examples for each.
3. Discuss one way in which plants can protect themselves against predati

Answer 1

Question 2) You set out to observe the symbiotic relationship between a species of fly. This species of orchid is only pollinated by this one species of fly, and the flies seem to prefer that orchid over any other flower for its nectar supply.

A. Propose two questions you would need to ask to determine the proximate causation for the species-specific preference of this fly.

B. Select one of the questions written above and write a hypothesis that could be tested experimentally.

C. Design a controlled laboratory procedure to test your hypothesis.

Answer 3

Questions 1) Organisms use a variety of mechanisms and behaviors to defend against environmental threats, predation, and disease. Respond to each of the following:
1. Discuss how the human immune system responds to an initial pathogenic exposure and how this initial exposure can lead to a quicker response following a second exposure to the same pathogen.

Your humoral or B-lymphocytes will make antibodies that would make Memory B cells to help if the infection comes back again. 1st time infected: Takes 20 days for full strength. 2nd time infected: 5 days to achieve maximum protection.

2. Discuss two types of animal behaviors that help defend against predation. Include specific examples for each.

Octopus will squirt a black ink to help it escape.
Puffer fish will inflate itself to have spikes to ward off predators.

3. Discuss one way in which plants can protect themselves against predation:

Plants can make secondary messages to give off a bad smell (Goo stuff on pine trees) or taste, or even poison (Poison ivy)
