Answer:
Chemotrophs are a class of organisms that obtain their energy through the oxidation of inorganic molecules, such as iron and magnesium
Explanation:
Answer:
Yeast cells are eukaryotic which means that they have a membrane-bound nucleus that holds their genetic information.
Eukaryotic cells also contain membrane-bound organelles such as:
- Mitochondria responsible for energy production
- Ribosomes responsible for protein synthesis
- Cell wall that protects the cell from the environment
- The Golgi apparatus that packages proteins
It also means that their cellular complexity is different from Prokaryotic organisms which lack membrane-bound structures for example the nucleus. Prokaryotic cells are mostly small and simple and Eukaryotic cells are typically a lot bigger and more complex.
Examples of other Eukaryotic cells:
- animals
- plants
- protists
- fungi

Xylem are tubes in the stem that transport water and minerals upward, from the roots to the leaves. Phloem are tubes in the stem that move food made in the leaves to other parts of the plant. ... Chlorophyll is a pigment that helps plants use energy from the sun to produce sugars.
Answer:
Sugars and phosphates
Explanation:
DNA is deoxyribonucleic acid.
The backbone is based on a repeated pattern of a sugar group (deoxyribose) and a phosphate group.
The image below shows one straightened-out strand of DNA with a backbone of alternating sugars and phosphates.
A is wrong. There is no ribose in DNA.
B is wrong. The nucleic acids A, C, G, and T join one strand of DNA to the other.
C is wrong. There is no RNA in DNA.
