Answer:
Skeletal system provide strength and protection to heart and also produces essential blood cells such as RBC and WBC
Explanation:
All organ systems in our body work in co-ordination with each other. Skeletal system comprised of bones and cartilages while cardiovascular system comprises of hearts, blood and blood vessels. Firstly the skeletal system protects the heart and also assists in its pumping along with muscle. Secondly, the blood cells such as RBC and WBC are circulated by the blood throughout the body. However these cells are produced in the bone marrow (inside the bones)

Answer:
Heterozygous for the gene
Explanation:
Alleles are the possible alternative forms of a gene. An organism having two identical alleles of a gene is said to be homozygous for that gene. On the other hand, an organism having two dissimilar alleles for a gene is heterozygous for that gene.
For example, let's suppose that I^A and I^B are the two alleles for ABO blood type in humans. Here, an individual with one copy of I^A and one copy of I^B would be heterozygous for ABO blood type. On the other hand, genotypes I^AI^A and I^BI^B are homozygous for the ABO blood type gene.
Answer:
B. Both mussels and barnacles live in the tidal ecosystems.
Explanation:
Mussels are <u>small bivalve molluscs that are adapted to both marine and freshwater ecosystems</u>. Barnacles, on the other hand, <u>are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and </u><u>tidal</u><u> zones</u>.
Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.
As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment.
