A and C
Fungi are classified as heterotrophs like animals.
<span>Because they absorb their food instead of making it.
</span>They
lack many of the important structures, like the roots, stems and
leaves. Their cell wall contains chitin not cellulose and they absorb
their food.
<span>They lack tissue differentiation and cell walls of chitin.</span>
Answer:
The chemical element which would be the most reactive with other elements is: D. helium, #2.
A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following:
- Tarnishing.
- Heat of combustion.
- Flammability.
- Acidity.
- Chemical reactivity.
Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.
Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.
The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.
Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.
In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.

Answer
A viroid is the smallest infectious pathogen they are made of insanely small circular RNA molecules(without any protein), they are similar to a virus but they are not the same.
Explanation:
<h2>Bacterial chromosome
</h2>
The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell
