Answers
Answer:
The correct answer is - the ancient observation that someone who had recovered from the plague could safely care for those newly diseased.
Explanation:
Immunological memory is the ability of the body to recognize or identify and kill or remove the antigen, very quickly and faster, the body has previously encountered and developed an immunological response.
These memories are developed due to memory B cells or, memory CD8+ T cells and memory CD4+ cells developed by the first-time immune response. If someone who had recovered from the plague must have developed memory cells for the antigen and safer than those newly diseased.

4. nonelectrolytes
Answers
Answer: what are the choices
Explanation: hi
When dissolved in water, electrolytes produce solutions of ions. The correct option is 2.
What are electrolytes?When electrolytes are dissolved in water or other solvents, they produce ion solutions that conduct electricity.
These ions, which can be positively or negatively charged (cations or anions), form when the electrolyte dissociates into its constituent atoms or molecules in the presence of a solvent.
Electrolytes include ions such as sodium, potassium, calcium, magnesium, chloride, bicarbonate, and phosphate.
These electrolytes are important in many physiological processes in the body, including fluid balance, nerve impulse transmission, and muscle function.
Food and drink, supplements, and intravenous fluids are all sources of electrolytes.
Thus, the correct option is 2.

- 22 haploid cells and an X or Y chromosome
- 23 diploid cells and an X and Y chromosome
- 22 autosomes and an X or Y chromosome
Answers
Answer:
22 autsomes and an X or y chromosome
Explanation:
Humans have 46 chromosomes. 23 from the mother and 23 from the father. The father has x and y chromosome. While the mother has two x chromosomes. 22 chromosomes each are given from both parents And the other chromosome (the 23rd) are the chromosomes for sex genes. Autosomes are all chromosomes that are not sex chromosomes. Therefore 22 autosomes are given from each parent. With reference to this questions 22 autsomes and one x or y chromosome will be given from the father.

C.chloroplast
D.cell membrane
Answers
Answer:
Explanation:
D
The structure that is found in the cytoplasm of plant cell is vacuole. The correct option is A.
What is vacuole?A vacuole is a cell organelle that is membrane-bound. Vacuoles are relatively tiny in animal cells and help to sequester waste material.
Vacuoles in plant cells aid in keeping water balance. A single vacuole can sometimes take up the majority of the interior space of a plant cell.
Within the cytoplasm of plant cells, there are also large, fluid-filled vesicles known as vacuoles.
Vacuoles typically make up about 30% of the volume of a cell, but they can fill up to 90% of the intracellular compartment.
Vacuoles are used by plant cells to regulate their size as well as turgor pressure.
Vacuole is a structure found within the cytoplasm of plant cells.
Thus, the correct option is A.

A cylindrical tin full of engine oil has a diameter of 12cm and a height of 14cm.The oil is poured into a rectangular tin 16cm long and 11cm wide. What is the depth of the oil in the tin?
Answers
Answer:
Depth = 9 cm
Explanation:
First, calculate the volume of the cylindrical tin.
Mathematically, that would be the following:
[tex]V = \pi * r^{2} * h[/tex]
Now, r = d/2 = 12/2 = 6 cm
h = 9 cm
Therefore, the volume will be:
V = 22/7 * 14 * 6^2 =1,584 cm^3
Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.
As we don't have the height of the tin so let's suppose it x, now it means that
l * b * h = 16 * 11 * x = 176x
Therefore, the depth would be:
176x = 1584
x = 1584 / 176 = 9 cm
