Answer:
D and B
Explanation:
We know that seeds need optimal amounts of water, oxygen, temperature, and light to germinate. Therefore the student would need to provide warmth because its winter and water because that would satisfy the need for moisture. Hope this helps!

Anabolic steroids are synthetic forms of the male hormone testosterone that are used to cause muscle hypertrophy.
It is properly knowns as anabolic-androgenic steroids (AAS). They are anabolic in nature and increases the protein found within the cells especially in the skeletal muscles. It also has varying degrees of androgenic and virilizing effect which includes inducing the development and maintenance of male secondary sexual characteristics such as facial and hair body growth.
In the 1930s AAS were synthesized and are recently used as a therapeutic medicine to stimulate muscle growth, increase appetite, induce puberty in males and treat wasting conditions among cancer and AIDS patients. It was also acknowledged by the American College of Sports Medicine that AAS, when joined with an adequate diet, can contribute to increasing the body weight, often as lean mass increases and the gains in muscular strength are achieved by doing high-intensity workout and proper diet.

Climate change is the greatest global threat to coral reef ecosystems. Scientific evidence now clearly indicates that the Earth's atmosphere and ocean are warming, and that these changes are primarily due to greenhouse gases derived from human activities.
</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
As temperatures rise, mass coral bleaching events and infectious disease outbreaks are becoming more frequent. Additionally, carbon dioxide absorbed into the ocean from the atmosphere has already begun to reduce calcification rates in reef-building and reef-associated organisms by altering seawater chemistry through decreases in pH. This process is called ocean acidification.

Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns. When combined, all of these impacts dramatically alter ecosystem function, as well as the goods and services coral reef ecosystems provide to people around the globe.
