Biology
1 answer:
Step2247 [10]3 years ago
5 0

Answer:

With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude. On top of Mount Everest, which is the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level.

Goryan [66]

Answer:

B) Natural selection favored rabbits that were resistant to the virus

Explanation:

Most likely, virus resistance occurred over time, as a consequence of mutation. Individuals that carried the resistance mutation become favourable by natural selection.

Natural selection is evolutionary mechanism which favours traits of an organism that help him survive and reproduce (increase organism's fitness). In the example above, resistant rabbits that survived had the favorable trait (resistance) by natural selection.

Why is the force of friction between two blocks reduced by adding dishwashing liquid between them?
DaniilM [7]

Answer:

The force of friction is reduced between the blocks by adding the dishwashing liquid because the liquid is slippery and this makes it difficult for the two surfaces to contact each other directly. Therefore the blocks slip past each other rather than grinding against each other, producing less friction.

Producers, consumers, and decomposers play important roles in the environment. Are there any organisms that would not fall into
choli [55]

Answer:

No, there are no organisms that will not fall into these categories

Explanation:

Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:

- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.

- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.

- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.

Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.
