A. The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.
<u>Answer:</u>
When there is excessive nitrogen then it will have negative effect on aquatic ecosystem because of the over nutrition in aquatic system.
<u>Explanation:</u>
- Nitrogen will drain away from soil and make the concentration of nitrogen high in water.
- This harms aquatic system by excessive growth of algae which will over shows the water surface and eventually block sunlight which is require for another aquatic organism.
- When those algae die, during decomposition, oxygen is consumed which will deficit oxygen for other organisms.
Answer:
B. Does not cointain a nucleus
Answer:
cephalochordates
Explanation:
Cephalochordata is one of the subphylos of the phylum Chordata with about 30 species. Cephalocords are small (centimeter long) animals, thin, laterally flattened (like the body of fish), transparent and live buried in sandy substrates leaving only their heads apparent. They are currently represented by the amphioxes. Cephalocords are the group of invertebrates that is most related to vertebrates.
The body of the cephalocordates is composed of longitudinal (horizontal) muscles that are divided by blocks called myotomes. The notochord holds in adults giving a stronger structure to the body.
Genes close to each other- Strongly Linked genes
Genes on different chromosome- unlinked genes
Genes apart from each other,but on same chromosome- linked genes
Explanation:
Linkage is defined as the tendency of genes located on same chromosome to be inherited together.
Genes located on different non-homologous chromosome are called unlinked genes.
Genes located on same chromosome are called linked genes.
Genes located close to each other are strongly linked as tend to show complete linkage.
Genes located on different chromosome tend to show incomplete linkage.
