Question

Answer Q1-Q4 choose a, b, c,d and e for each questions to Answer

Q1.If you find a group of organisms that all appear to have similar appearances, you could say that they belong to the same species within kingdom Animalia if ____.

a. they are eukaryotic, regardless of whether they are multicellular or single-celled

b. they are multicellular eukaryotes that look different from other organisms in the area.

c. they are multicellular eukaryotes that look the same.

d. they are eukaryotic and not found elsewhere

e. they are multicellular eukaryotes that can mate and produce fertile offspring.

Q2.Why are frogs a good indicator species?

a. They are resistant to increases in ultraviolet light.

b. They are of considerable economic importance.

c. Their numbers can be manipulated easily with minimal effects on other species.

d. They are increasing in number, suggesting that they are resistant to environmental degradation.

e. Their eggs do not have hard shells to protect them from environmental contaminants.

Q3.What is a reason that it is particularly important to protect amphibian species?

a. They are especially resilient and likely to survive even if others don’t if environmental conditions are degraded.

b. They are unusually abundant and therefore extremely important to protect.

c. They are able to rapidly increase in number.

d. They are well-adapted to survive changing environmental conditions.

e. They are often important in their communities and other species may go extinct if they are not present.

Q.4An animal that has very specialized requirements and only lives in a very small area of habitat ____ compared with an animal that has a wider range and more diverse requirements.

a. has a lower risk of extinction

b. has a higher rate of evolution

c. has a lower risk of losing its habitat

d. has a higher rate of migration

e. has a higher risk of extinction

Answer 1

1- Correct option is (c): They are multicellular eukaryotes that look the same.

All members of kingdom Animalia are multicellular; eukaryotic and heterotrophs.

2- Correct option is (e): Their eggs do not have Hard shell to protect them from environment contaminants.

Frogs are considered as indicator species, as they are the first to be affected by degradation in environment, they are amphibians that is live in aquatic as well as terrestrial ecosystem so any decrimental change in both the ecosystem directly affect frogs , their eggs are also not hard thus degrade when their is environmental degradation.

3- Correct option is (e): They are often important in their community and other species may go extinct if they are not present.

Amphibians play important role in ecosystem, specially in wetland and forest ecosystem. They are integral part of food webs .

4- Correct option is (e): Has a higher risk of extinction.

If an organism has a very specialized requirements and has very small range of habitat, it's likely to be that it will extinct due to exploitation of limited resources; intraspecific competition for food, mating etc.
