17. _______Is a process that could be used to separate dissolved particles from the liquid in a solution.

Answers

The process of separation of the dissolved particles from the liquid in a solution is known as  distillation. In the process of distillation, the particles are separated from the liquid solution by the method of condensation and selective boiling. The separation from this process may be complete or partial. This method is used in the production of alcohol, gasoline, distilled water etc.

Hence, the blank can be filled with 'distillation'.

Distillation is a process that could be used to separate dissolved particles from the liquid in a solution.

23. How many total chromosomes are in a germ cell in the testis of this organism that is in Metaphase of Meiosis II?

Answers

There are 46 chromosomes in each cell at metaphase II in meiosis in humans. Normal human body cells each have 46 chromosomes. Prior to meiosis, the DNA replicates and each cell gets 92 chromosomes.

Final answer:

A germ cell in the testis in Metaphase II of Meiosis has 23 chromosomes.

Explanation:

In Metaphase II of Meiosis, the chromosomes line up at the equator of the cell and are ready to be separated into two daughter cells. Each daughter cell will receive half the number of chromosomes as the parent cell. In humans, the diploid number of chromosomes in a somatic cell is 46, while the haploid number of chromosomes in a germ cell is 23.

Therefore, in Metaphase II of Meiosis, a germ cell in the testis would have 23 chromosomes.

A student examines a cell under the microscope and determines that it is a eukaryote. All but one structure could help the student come to this conclusion. Which structure is of no help?A) cell wall
B) Golgi body
C) mitochondrion
D) membrane-bound nucleus

Answers

Answer:

A) cell wall

Explanation:

The cell wall does not help differentiate prokaryotic cells from eukaryotic cells, since both have the cell wall (formed by polysaccharides and amino acids).

The other structures help identify the eukaryotic cell due to the fact that only this type of cell has them, while prokaryotic cells lack organelles such as mitochondria and the golgi complex.

In addition, prokaryotes do not have membrane-bound nuclei, and due to their less complex structure, their genetic material is dispersed in the cytoplasm.

Answer:

the answer must be A.

What is a string of nucleotides called?

Answers

A string of nucleotides that hold information is called a gene

Final answer:

A string of nucleotides is called a DNA sequence. DNA sequences are composed of four different nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). These sequences are the building blocks of genes and determine the genetic information of an organism.

Which of the following is not a risk factor for water intoxication?a.a low body mass
b.heat stress
c.resting
d.overexertion

Answers

The answer is c. resting. Water intoxication, also known as hyperhydration or water poisoning, is a fatal condition caused by too much electrolytes in the body from drinking too much water in a short period of time. The rest of the choices are results of this condition. Additionally, water intoxication can be caused by psychiatric conditions, endurance sports, and iatrogenic care.
