Answer;

(3) the concentration of the substance is greater outside the cell than inside

Explanation;

-When a substance is of low molecular weight and has a higher concentration of the substance outside the cell as opposed to inside the cell then it is most likely to diffuse into a cell.

-Diffusion involves the movement of molecules from a region of high concentration to a region of low concentration, therefore if molecules are highly concentrated outside the cell then they are likely to move into the cell. Additionally, the size or the molecular weight of the molecules determines whether they will move into to the cell as the cell membrane only allows movement of materials in or out of the cell selectively.

natali 33 [55]

If you were to compute this, Angle C should be equal to 100°.

In a triangle, all angles sum up to 180°.

In triangle ABC, where the m∠A =30° and m∠50°:

m∠A + m∠B + m∠C = 180°
30° + 50 + m∠C = 180°
80° + m∠C = 180°
m∠C = 180° - 80°
m∠C = 100°

The triangle should look like the picture attached.

Answer:

Semantic Encoding

Explanation:

Encoding is the process of getting information into memory for storage. It involves associating it with objects, sound, visions etc

Semantic encoding is a specific type of encoding in which the meaning of something is encoded as opposed to the sound or vision of it. Research suggests that we have better memory for things we associate meaning to and store using semantic encoding

The process of breaking the information down into a form we understand is the process of encoding

What would be the ploidy of the viable gametes produced by a tetraploid individual if nondisjunction of all chromosomes occurred

sattari [20]

Answer:

Tetraploid

Explanation:

Ploidy:

Ploidy is a biological term used for the presence of number of chromosome sets in a cell. Cells can be haploid (gametes), diploid (two chromosomal sets) and polyploid (more than two chromosomal sets).

Polyploidy:

A condition that entails the possession of more than two sets of chromosomes in the cell. Normal cells are diploid (2n) i.e they contain two sets of chromosomes, one from each parents. Polyploid individuals contain three (triploid, 3n), four (tetraploid, 4n), five (pentaploid, 5n) number of chromosomes and so on.

Under normal disjunction of chromosomes, a tetraploid cell will produce two diploid daughter cells each with two sets of chromosomes.

However, in the case of non-disjunction of all chromosomes in a tetraploid individual, two tetraploid daughter cells will be produced at the end of meiosis 1.

Non-disjunction of all chromosomes means that one daughter cell has received all 4 sets of chromosomes while the other is null i.e. contains zero chromosomal sets.
