Answer:
adsorption, penetration, biosynthesis, maturation, release
Explanation:
The virus after infecting the cell produces several progenies which after reaching a certain number cause the lysis of the cell and are then released out from it. This process of entering the host by the virus and then lysing the cells to be released is termed as a lytic cycle.
There are 5 stages involved in this lytic cycle:
1. Adsorption - when the virus finds its attachment site on the bacteria it gets attached to the viral receptor and then is adsorbed on the bacteria, this is the first step required to gain entry into the host.
2. Penetration - once the virus is attached to the host the next step is to penetrate it and enter inside the cell. For this, the virus secretes lysozyme and then inserts its genetic material inside the cell.
3. Biosynthesis - this stage involves the utilization of the enzymes and nucleotides of the host to make up the DNA of the phage.
4. Maturation - once the phage DNA is made the next stage is to assemble the phage DNA with the capsid and this is termed as maturation.
5. Release - this step involves the breakage of the plasma membrane of the host cell and the release fo the phage particles.
Answer:
Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.
the answer is B. The cell would not be able to get enough of the gases and nutrients it needed. I just answered this question on the lesson and it said it was correct. I hope this helps!

The cardiovascular system is also known as the circulatory system.It is made up of the heart, the blood vessels namely arteries, veins and capillaries, and approximately five liters of blood.The circulatory system's major functions are to transport oxygen, hormones, and nutrients to every cell in the body, and to tale away cellular waste products from the cells such as carbon dioxide and bring them to excretory organs where they are expelled out of the body.
