The role of a keystone species is..
A. To kill off invasive species in the area
B. To maintain biodiversity in the ecosystem through complex interactions with other animals in the area
C. To be able to make the environment safe

Answers

Answer 1

Answer:

The answer is B

Explanation:

A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.

Read the excerpt from How Hurricanes Form.

Hurricanes are often compared to engines. Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.

Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.

The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing. The system rotates faster and faster until the eye of the storm forms in the center area. Ironically, the eye of the storm is the calmest part, and it has very low air pressure. The higher pressure above the hurricane continually flows down into the eye.

(5) If the coral dies, the reef becomes bare rock and sand no longer full of life.

Answers

Answer:

(5) If the coral dies, the reef becomes bare rock and sand no longer full of life.

Explanation:

The atmosphere is a part of coral reef because a large population of organisms lives in these coral reefs. It provides habitat to the biosphere of the  ocean as well as oxygen to the marine organisms. It can greatly affected with the increase concentration of carbondioxide due to acidification of water that kills the algae that is lives on the surface of these coral reef. So if these algae die due to lowering of pH, a large portion of marine organisms also removed from the environment due to unavailability of suitable environmental conditions.

A can of antifreeze spills near a clump of Dryopteris dilatata, a type of fern. The chemical seeps into the ground, endangering the plant's roots. The plant roots grow as far away from the chemical as possible to absorb only fresh water and minerals.
During this process, the roots primarily work in conjunction with which system? a) The immune system to defend against the toxic chemicals
b) The vascular system to reduce the absorption and transport of toxic chemicals
c) The reproductive system to make more root cells
d) The digestive system to create enzymes that break down the toxic chemicals​

Answers

Answer:D

Explanation:

I got it right on my test

Dryopteris dilatata is in family Dryopteridaceae. The movement of plant away from spill the roots primarily work in conjunction with vascular system to reduce the absorption and transport of toxic chemicals.

What is Dryopteris dilatata?

Dryopteris dilatata is a fern mainly located in deciduous or semi-evergreen family, native of Europe.

It can be grown in most cool, moist and light shaded areas. It is also called as broad buckler-fern.

As to avoid antifreeze spills, the plant roots grow far away from the area of spill. During this process roots primarily work with vascular system to reduce absorption and transport of toxic chemicals.

Thus, the correct option is b.

Polar bears live in the tundra. They obtain their energy almost exclusively from eating other animals, although they do eat some vegetation. Black bears that live in temperate forests tend to be more omnivorous, eating a wide variety of plants and animals for energy.

An adaptation is a behavior or an anatomical structure that can help an organism survive in its environment. Why are diet choices important adaptations for these animals’ survival in their biomes? Based on the images, what other adaptations do these animals display?

Answers

Answer:

In the tundra, vegetation is rare, so polar bears had to adapt to eat a heavily animal-based diet. In the temperate forest region, a wider variety of plants is available, so black bears can eat a more omnivorous diet. The bears’ colors are adaptations. The polar bear blends in with the snowy background, and the black bear blends in with the trees of the temperate background. The bears’ coloring could help them hunt for prey.

how can a predator prey relationship cause coevolution

La coevolución impone presiones selectivas. Éstas a su vez llevan a una carrera armamental de adaptaciones mutuas progresivas

Explanation:

Explanation:

Coevolution

Coevolution is a cyclic process in which the adaptations of one organism in an ecosystem drive the adaptations of another organism. These adaptations then cause the first organism to adapt to keep up (Brockhurst & Koskella, 2013). Coevolution is very environmentally specific so you will not see it develop between generalist species (Abrams, 2006; Aslan, et. al, 2013; Becklin, 2008; Chu, 1985) though it may develop communally. Similarly, coevolution does not account for wide-scale adaptions among groups of organisms better attributed to environmental shifts such as habitat destruction and climate change (Chu, 1985).
