The blood cells likely placed in a "hypotonic solution".
<u>Option: A</u>
<u>Explanation:</u>
When human blood cells are immersed in a solution with a low concentration of solute than is present in cells, osmosis allows water to pass through the cells, allowing the cells to get swollen; such a fluid is hypotonic to the cells. But when held in a solution with a greater concentration of solute, osmosis allows water to pass out of the cell, the cell is smaller and crenated in form; then a solution is hypertonic to the cells.
Healthcare facilities preserve human blood cells in a plasma solution that has the proper salt and protein ratios. Such solution is formulated to be mildly hypertonic to the red cells, thus maintaining the integrity of the cells and avoiding hemolysis.

Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>
Answer:
B. AUU CGC AUC UUG AAC
Explanation:
<em>According to the rule of base pairing in DNA, the pyrimidine bases always pair with purine bases. Specifically, adenine (A) always pair with thymine (T) while Guanine (G) always pair with cytosine (C). In RNA, thymine is replaced by uracil (U).</em>
Hence, TAA GCG TAG AAC TTG will give
AUU CGC AUC UUG AAC.
The correct option is B.
Answer:
A. spiral galaxies are not pinwheel-shaped
Explanation:
There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.
Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.
Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.
Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.
Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
