1. DNA is double stranded, while RNA is single stranded
2. DNA contains the sugar deoxyribose; while RNA containers the sugar ribose
3. The four nitrogenous bases that are a part of DNA are guanine, cytosine, adenine, and thymine; in RNA, the four nitrogenous bases are guanine, cytosine, adenine, and uracil (the uracil in RNA replaces the thymine in DNA)
Hope this helps :)
The Virus is a single molecule of nucleic acid surrounded by a protein coat, and the capsid.
<h3>
Why virus is a cellular agent that possesses membrane-bound organelles?</h3>
The above statement is totally False because the Virus are the non-living agents and they required a host cell to complete their life cycle. The Virus can not be classified under and classification system. Lister first promoted the use of disinfecting agents prior to surgery. Virus are very small agents that rely on living cells to multiply. The Virus may use an animal, plant, or bacteria as a host to survive and reproduce the same virus inside the body of host.
So we can conclude that the Virus is a single molecule of nucleic acid surrounded by a protein coat, and the capsid.

Answer:
c. The flea beetle can become an invasive species
Explanation:
An invasive species is a non-native species that is introduced to the population (for example by humans). Because they are non-native, they can disrupt the 'natural order' of things. I.e., they can change the function of the ecosystem, which develops naturally to result in a harmony.
In this example, the leafy surge is a good example of an invasive species, it was accidentally introduced and has grown out of control, damaging the range land. In an attempt to control this, we deliberately introduced <em>another non-native species</em>.
This is in an attempt to fix the original mistake. If it works, then great! But if the flea beetles don't actually eat the leafy spurge, and they reproduce so quickly... it means we have introduced an additional species that could also disrupt the ecosystems. This could then mean that the flea beetle becomes an invasive species.
Answer:
b) Glutamate's negatively charged R group mimics a phosphorylated serine residue. The Vmax is reduced because the carboxyl group is smaller and less charged than a phosphate group.
Explanation:
Vmax is the maximum velocity of a reaction. It is achieved when all the binding sites of an enzyme are occupied. Glycogen phosphorylase enzyme has a serine residue on position 14. Serine is important for its activity because serine's phosphorylation activates it. Hence, phosphorylated Glycogen phosphorylase is active.
Serine has a hydroxyl group which acts as a nucleophile leading to its phosphorylation and addition of negative charge. Glutamate is already a negatively charged amino acid so it repels the phosphoryl group. However because of its negative charge it acts like phosphorylated serine, making the enzyme functionally active. But due to lesser negative charge and smaller size as compared to phosphoryl group, it is not able to fully restore the wild type Vmax.
Answer:
Photosynthesis releases oxygen
Explanation:
and oxygen is used for breathing if you didn't know :D
