Answers

Answer 1

Answer:

The correct answer would be immunisation.

Immunisation refers to the process of developing immunity against a particular pathogen or disease.

In this process, a vaccine consists of attenuated or heat killed pathogen is administered into a person.

The body produces a primary immune response against the weakened pathogen or antigen. It also develops memory of the pathogen due to which body is able to recognise the pathogen easily if it encounters the same in near future.

It helps the immune system to produce quicker and amplified immune response against the pathogen and our body becomes immune to that particular disease or pathogen.

Thus, immunisation is required before travelling to Africa as yellow fever is very common there.

Which of the following best explains ways in which fish and mammals differ? (2 points)Fish are invertebrates and have scales and paired fins, while mammals are vertebrates and have fur or hair.
Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring.
Fish are endothermic and have gills, while mammals are ectothermic and have lungs.
Fish have streamlined bodies and three-chambered hearts, while mammals are bipedal and have four-chambered hearts.

Answers

The answer is Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring.

Through the elimination process:
* Fish are invertebrates and have scales and paired fins, while mammals are vertebrates and have fur or hair. - Fish are vertebrates!
* Fish are endothermic and have gills, while mammals are ectothermic and have lungs. - Fish are ectothermic (cold-blooded), and mammals are endothermic (warm-blooded)!
* Fish have streamlined bodies and three-chambered hearts, while mammals are bipedal and have four-chambered hearts. - Fish have four chambered hearts and not all mammals are bipedal!

This leaves choice: Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring. All of this is true, but it should be taken into consideration that some fish give live birth and some mammals lay eggs, but this is the most possible choice among all mentioned.

Answer: Fish are ectothermic and lay eggs to reproduce, while mammals are endothermic and give live birth to offspring.
