Cell walls are made out of cellulose and they give a sturdy structure to the cells (if you notice they have a rectangular shape)
Answer:
1- DNA replication: two identical DNA strands
2- Transcription: mRNA
3-Translation: proteins
4- Mitosis: two identical diploid somatic cells
5- Meiosis: four different haploid gamete cells
Explanation:
1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created
2- Transcription: the process by which DNA becomes mRNA
3-Translation: the process by which mRNA becomes proteins
4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells
5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells
D. both plants and animals need freshwater to live
The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex.
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.
<span>These are viroids. They are some of the smallest types of matter that have been shown to take on the properties of living beings. They have the ability to replicate, while not having many of the mechanisms that are commonly found in DNA and required for them to replicate.</span>
