Answer:
The correct answer is: Hydrophobic, Hydrophobic.
Explanation:
- Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
- The amino acids can be broadly classified into non-polar and polar.
- The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
- The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.
When we talk about meiosis I and II we talk about gametes formation.
The objective is to create cells with half DNA charge, called haploids.
At the meiosis I, in prophase I, crossing over happens and anaphase separated homologous chromosomes.
In the end, you still have cells with all DNA charges (2n).
To start meiosis II cells does not duplicate its DNA. When anaphase II happens sister chromatids split, and you end with half DNA charge cells. Haploids or (n).
Answer:
A tissue
Explanation:
Cells are grouped together to carry out specific functions. A group of cells that work together form a tissue.

4, Radiated heat from the Sun being absorbed by the ground.
Answer:
It is black on white.
Explanation:
Zebra have white bodies, with the black (and sometimes brown) strips of fur.
You can tell because the stripes end at the belly of the zebra, which is white.
