Symbioses are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called mutualisms.
In mutualism the relationship benefits the two organisms, the relationship can be within the species, between living things fro two different species among others. Example is the digestive bacteria and humans; Some food cannot be digested, therefore when these foods are consumed, the bacteria in the digestive tract feed on these foods, therefore the bacteria stays alive and humans gets helps in digestion.
Sunlight. Based on the sunlight you receive you have three zones.
1. Sunlight zone- There is enough sunlight here and photosynthesis can happen. More than 90% of marine animals live in this zone.
2. Twilight zone- A small amount of light is here and no plants grow here. The fish who live here are the ones who have adapted to the little light. Lantern fish is an example.
3. Midnight Zone- 90% of the ocean is in this group. It is entirely dark and the temperature is freezing.
Answer:
B. A group that is treated the same as other groups except for the variable being tested.
Answer:
All the puppies have black hair because albino alleles are found in two different genes.
If we let the letters A and B represent the two different pigmentation genes, the one of the dogs is AAbb, and the other is aaBB.
Their offspring are AaBb and so there are not albinos because they have one dominant copy of each gene.
