Answer:
Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid—either DNA or RNA—never both.
Explanation:
Rainfall will increase due to rising temperatures which will increase the risk of flooding.
Answer:
Due to their hole size.
Explanation:
Some molecules can pass directly through the phospholipid bilayer because of their small size which can easily pass through the small holes of phospholipid bilayer, while those that are too large or too charged need to pass through a membrane protein because membrane protein has a large holes through which large molecules can easily pass through the semi-permeable membrane of the cell by active or passive transport.
The DNA in our cells nucleus is wrapped around proteins called histones, forming chromosomes which in turn codes for our genes.
