What happens that makes rain start to fall from a cloud? ​
Shkiper50 [21]

Answer:

when water vapor turns into clouds

Explanation:

Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. ... In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.

Think of a change that can occur to an ecosystem and the populations that live in that area. In what ways can the different popu
Alex73 [517]

Answer:

There are several environmental factors that causes changes in the ecosystem and the population of that area such as invasive species, extreme weather, land use change, pollution and disease.

Lets take invasive species as environmental factor. Introduction of invasive species can cause a huge change in the ecosystem and affects the native population in that area. it increases the competition for food resources and decreases the survival rate of their preys.

For example: Water hyacinth (Eichhornia crassipes). It is an invasive plant species that has very bad impact of native population as well as other population, like it reduces biological diversity, oxygen loss, decreased phytoplankton productivity,  eliminate plants that animals use for nesting, and alter animal communities by blocking access to the water.

Thus invasive population can affect population by reducing biodiversity, water shortages, decreasing availability and quality of key natural resources, disturb the food chain and can cause natural calamities.

Invasive species affect the resources that native species are using and that decreases the carrying capacity of the native population as it disturbs the whole food chain.

dalvyx [7]

Answer:

True. You can get vitamin A as "preformed vitamin A" which is already active and/or you can get vitamin A as carotenoids which the body can turn into active vitamin A.

Explanation:

There are two different types of vitamin A that can be obtained from food:

1.  Preformed vitamin A, which is already active, is found in animal products such as beef, fish, poultry and dairy products.

2. Provitamin A, which is the inactive form, is found in plant-based foods, such as fruits and vegetables. The most common type of provitamin A is β-carotene, which is a carotenoid that the body can turn into active vitamin A via an enzyme named β-carotene 15,15'-monooxygenase.
