Answer:
<em>The correct option is d) an ecotone</em>
Explanation:
An ecotone can be described as an area of transition between two different biomes. An estuary can be described as an ecotone where the river water meets the seawater. The freshwater biome mixes with the seawater biome in an estuary. Unique plants and animals are grown in an estuary which are adapted to live in such an environment. The water present in an estuary is termed as brackish water. Hence, the correct option is d.
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.
The only answer that could be considered an advantage is C. Increasing the amount of crops harvested.
Answer:
Yes, 75%
Explanation:
Since the first offspring produced between the ram and the ewe was black you can determine that both sheep have a recessive and dominant allele. Both of the parent's genotypes would be Ww, this is because they both have the white phenotype and they were able to produce a black offspring. Since both parents have a genotype of Ww the probability of a black offspring being produced is 25% and 75% for a white lamb.
