Answer:No one knows exactly how many species live in the world's tropical rainforests — estimates range from 3 to 50 million species — rainforests are the undisputed champions of biodiversity among the world's ecosystems, containing far higher numbers of species on a per-area basis relative to sub-tropical, temperate, and boreal ecosystems. For example, whereas temperate forests are often dominated by a half dozen tree species or fewer that make up 90 percent of the trees in the forest, a tropical rainforest may have more than 480 tree species in a single hectare (2.5 acres). A single bush in the Amazon may have more species of ants than the entire British Isles. This diversity of rainforests is not a haphazard event, but is the result of a series of unique circumstances.

Explanation:
If 4 grams of water vapor are present in a cubic meter of air that can hold a maximum of 10 grams, what is the relative humidity?
Answer:
40%
Explanation:
The relative humidity refers to the ratio of water vapor present in the air and the maximum amount of water vapor that the air can hold at a given temperature.
Mathematically, it can be expressed as;
Relative humidity = amount of water vapor in the air/maximum amount of water vapor the air can hold x 100%
In this case,
Amount of water vapor in the air = 4 grams
Maximum amount of water vapor the air can hold = 10 grams
Relative humidity = 4/10 x 100%
= 40%
Hence, the relative humidity is 40%.

Is the Amazon Rainforest Resilient or Fragile to change and why?
I thought Resilient because the rainforest has changed over time because it was fragile before.
Answer:
Resilient.
Explanation:
Amazon Rainforest is more Resilient to change because Amazon rainforest has evolved over millions of years. Amazon rainforests may be more resilient to climate change induced by carbon dioxide due to storing a lot of carbon as living biomass. The climate change is unable to change the Amazon rainforest due to their dense vegetation but if the rainfall patterns changes means the Amazon rainforest experience less rainfall due to climate change so it has a change this Amazon rainforests.

Volcanic deposits occurs as a result of materials that is emitted from a volcanic eruption which can be used as a building materials.
State two differences between respiration and breathing
Answer:
1. Respiration results in the production of energy and Breathing doesn’t provide energy.
2. Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation while respiration is a biochemical process to release energy from organic compounds which are then used for performing different physical activities.

Explanation:
a predator population suddenly decreases even though the prey population stays the same. Besides disease, what could explain this change?
Answer:
hunting, the predator is in the middle of the food chain
Explanation:
hunting can WIPE OUT species as shown by the dodo bird in the past.
food chains often work as 1-2-3 or 1-2-3-4 in levels.
A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.
What happens if in a particular food web a new prey animals are introduced?If in a particular food web a new prey animals are introduced, that will most likely result in the increase of the populations of the predators in that food web. The reason why the populations of the predators would increase is that there will be more pray to hunt, and more food means that the predators can increase in numbers and not suffer from food shortage.
Still, while this the most likely scenario, it has to be taken with a little bit of reserve, as it also depends on what kind of prey animal would be introduced in the food web, and what kind of predators are there in the food web. The predators in that food web are small to medium sized predators like the serval, honey badger, than there will be no increase in the predator populations as they will not be able to hunt the introduced pray animal.
Therefore, A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.

What is the benefit of using sunscreen when working outside every day?
Answer:
Not only does it protect from UV rays, it also works to reduce the appearance of pores and fine lines over time, so you're actually improving your skin while wearing it.
Explanation:
Answer:
It prevents cancer.
Explanation:
UV rays penetrate the many layers of the epidermis, reaching the deep layers of our skin, which is meant to be protected. This activates pigment cells, releasing Melanin and darkening the skin.
When the UV rays penetrate these deep cells, it reacts similarly to radiation, denaturing and breaking apart DNA. If enough damage is done and the cell becomes irreparable a tumor forms.
Consistent exposure to UV rays has detrimental effects because it puts your skin cells through this same stress every day.
