Answer:
The law of conservation of mass states no matter is created or destroyed. This means that the matter currently on Earth is the only matter that will ever be available to us. However, it also means that this matter will not be destroyed. So, water, oxygen, carbon, and nitrogen are all used by living things in our world and then recycled to be used again.
One example of this is the water cycle. More water is never added or taken from the world, it is just reused. First, water starts in some body of water and then evaporates into the air. Then, the water falls back to Earth as precipitation.
Once a hypothesis is tested and confirmed, and then tested again and confirmed again by many others, it may provide the basis for, or become a part of, a scientific theory.
Answer:
Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases
Explanation:
Answer:
<em>Bright white fur 3/4</em>
<em>Black fur 3/16</em>
<em>brown fur 1/16</em>
Explanation:
From the Punnet's square analysis (see the attached image);
- <em>A_B_ 9/16 </em>
- <em>A_bb 3/16</em>
- <em>aaB_ 3/16</em>
- <em>aabb 1/16</em>
A_B_ and A_bb will always give offsprings with bright white fur since allele A always mask the effect of B.
aaB_ will always give offsprings with black fur since allele a does not produce any protein.
aabb will give offsprings with brown fur since b codes for brown fur colour.
Hence, the phenotypic ratio of the offspring will be;
<em>Bright white fur 3/4</em>
<em>Black fur 3/16</em>
<em>brown fur 1/16</em>
