Answer:
Greenhouse gases absorb radiation from the sun and re-radiate it back toward the <u>atmosphere,</u> which helps to maintain a normal range of <u>temperature</u> on Earth.
Greenhouse are glass house which are used to grow crops in regions exhibiting extreme cold temperatures and snow fall. The soil in these regions are frozen therefore, are not suitable for plant growth. These glass houses trap the sunlight which is used by the plants for photosynthesis and growth. Some gases like methane, carbon dioxide, carbon monoxide, sulphur and nitrogen dioxide are released into the atmosphere. These gases maintains the range of temperature of atmosphere.

Explanation:
Inquiry about nocturnal muscle spasms would be most significant when taking the musculoskeletal history of <u>older adults.</u>
This is because older adults often get up at night due to pain and cramps in their bodies, because their muscles are spasming from time to time. The other options, adolescents, infants, and children, as well as middle adulthood, do not experience these problems as much, which is why they wouldn't be suitable for this research.
This is not a concern to scientists because this is an indication that a new species may be formed or in progress from the interbreeding.
Explanation:
We know that species are the populations that can mate to produce fertile and viable progeny. Speciation occurs when new species is form by a population which has separated and become reproductively isolated.
The two dogs living in Africa and America can mate and produce healthy offsprings and they are phenotypically different.
The mating of horse and donkey are different species because they produce infertile mule.
When two population of species that are phenotypically different mate they have overcome the mechanism of reproductive isolation.
