Question

The forest with a multilevel understory is tropical rain forest temperature deciduous forest coniferos forest fundra only a and b Eagles and bean food on spawning valmon. If shrimp are introduced that compel salmon for food the salmon population will decline, the eagle and bear populations will decline both a and b are correct only the shrimp population will decline Which of the following would NOT be involved in natural selection? competition for resources having successful offspring variation in DNA sequences embryological similarities Automobile exhaust nitrogen oxides, and sulfur dioxides from power plants cot to produce a weak carbonic acid and an increased number of H+ ions, re the effect known as: greenhouse effect ozone hole effect climate change effect acid rain effect

Explanation / Answer

Question 26.

Answer is d. acid rain effect

Explanation:

The pH of normal rain water is slightly acidic (5.3-6.0), but when carbon dioxide and water present in the air will combine to form carbonic acid and releases excess of H+, pH level of rain water will fall resulting in acid rain.

Question 25)

Answer d. embryological similarities

Embryological similarities are not involved in natural selection

Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.

Question 24)

c. Both a and b are correct.

When shrimp will compete with salmon for food, obviously the salmon population will decrease. The eagles and bears which are dependent on salmon will not get sufficient food, thus both eagles and bears population will decline.

Question 23

Answer is e. only a and b

The forest with a multilevel understory is tropical rain forest and temperate deciduous forest and here being understory the plant life will be seen growing beneath the forest canopy and light will not be penetrating it to any great extent

Question 22

Answer c. long growing season

In physical geography, we can see in tundra where the tree growth will be hindered by low temperatures as well as short growing seasons
