Answer:Acer represents the genus name while
saccharum represents the species.
Explanation:
In a way to classify organisms, biologists used certain important common features to structure them into groups. The arrangement of living organisms in this hierarchy from the highest level to the lowest is as follows:
Kingdom--> phylum-->class-->order--> Family-->genus--> species.
The largest group of organisms is kingdom while species is the smallest unit of classification.
The common name of the plant used in the question above is sugar maple. Biologist, however, use a standard system to name living organisms. Each kind of organism is given two names, hence the term BINOMIAL NOMENCLATURE.
--> The first name is the name of the genus to which the organism belongs.
--> The second name is the name of the species to which it belongs.
Both names are printed in italics with only the genus name having an initial capital letter. Hence, the scientific name of sugar maple is Acer saccharum( in italics).
Answer:
The genotypic ratio and phenotypic ratio are different when a monohybrid cross is done because multiple genotypes often result in the same phenotype.
Its skin so it protects the internal organs and systems
Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.
Explanation:
When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.
As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.
Thanks to its memory cells, the virus will remain much less time in the body.
Answer:

Explanation:
An element only has <u>one</u> type of atom and cannot be broken down by chemical means.
Let's analyze the answer choices.
1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.
2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.
3. This has one type of atoms, so it is an element.
Therefore the best answer choice is 3.
