Answer: Water. The pH level is 7.
Explanation: The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic.
I believe that the answer is that a chromatid is one half of a replicated chromosome, whereas chromosome consist of DNA wrapped around proteins in a highly organized manner. A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.
Answer:
Attachment stage
Explanation:
Viruses are organisms that are incapable of replicating on their own, instead they infect a living host in order to make use of its transcriptional, replication and gene expression abilities to multiply. This process of infection characterizes the reproductive life cycle of the viral cell.
Normally, viruses are specific when infecting their hosts but they generally commence the infection cycle with ATTACHMENT. In this stage, the viral cell with the aid of its proteinous capsid binds to specific receptor site on the cell membrane of its host cell before making entry by incorporating its genetic material.
Answer: Trail 1
Explanation:
They apply the least amount of force
The answer is B because:
Cell walls are made of cellulose and proteins (hence II).
Animal cells don't have cell walls (only cell membrane) but plant cells do so IV
They must be semipermeable since materials for example carbon dioxide and water for photosynthesis have to go into the cell <em>some</em> way.
