A mosquito has a diploid number of 6. How many chromosomes are in the sperm of a mosquito?
3
6
12
24
Answer:
3
Explanation:
Cells contributing to the structure of the mosquito's stomach are non-sex cells, and are therefore diploid, so the number of chromosomes would be 6.
Sperm cells, being gametes, are haploid, so the number of chromosomes present in a sperm cell is 3.

A 2-gallon container of laundry detergent costs $38.08. What is the price per cup?
Answer:
$1.19 per cup
Explanation:
So there are 32 cups in 2 gallons (16 cups per gallon) and we already know how much the whole container costs. So now all we have to do is come up with an equation, such as $38.08/32.
38.08/32 = 1.19
To solve this we must be knowing each and every concept related to gallon. Therefore, $1.19 is the price per cup when a 2-gallon container of laundry detergent costs $38.08.
What is gallon?The gallon presently has one definition inside the imperial system and two in the US customary system (liquid and dry). There have been several definitions and redefinitions throughout history.
Similarly, a Gallon is the standard unit of volume which denoted as “gal”, mainly used to measure the liquid Quantity in the customary systems of the United States and the Imperial System of measurement of the united kingdom.
there are 32 cups in 2 gallons
the price per cup=38.08/32 = $1.19
Therefore, $1.19 is the price per cup when a 2-gallon container of laundry detergent costs $38.08.

What is the definition of a hydrocarbon
Answer:
a compound of hydrogen and carbon, such as any of those which are the chief components of petroleum and natural gas.
Explanation:
A hydrocarbon may be defined as an organic compound that significantly consists of units of carbon and hydrogen in its structure. In other words, we can say that any substance which is made only of carbon and hydrogen is known as Hydrocarbon.
What are the functions of hydrocarbons?The functions of hydrocarbons are as follows:
They are principal constituents of petroleum and natural gas. They serve as fuels and lubricants.They function as raw materials for the synthesis of plastics, rubbers, solvents, fibers, etc.Hydrocarbons are colorless and odorless substances. They specifically undergo a combustion reaction with oxygen and finally deliver carbon dioxide and water.
The melting point of hydrocarbon depends on the number of carbon associated with it. Greater the number of carbon associated with a compound, the higher the melting point of hydrocarbon.
Therefore, the definition of hydrocarbon is briefly described.

PLEASE HELP The table below lists some problems associated with four organs of the human digestive system. Which organ is most likely the stomach?
Answer:
ORGAN 1 --> Acid inside the stomach begins to dissolve some of its tissue lining.
Organs are structures made from a group of the same and different tissues. The breakdown of the tissue lining from acid shows that the organ is the stomach. Thus, option A is correct.
What is the digestive system?The digestive system is an organ system that includes the stomach the organ involved in the digestion of the foods into a small particle that provides energy to the body. The acid is present in the stomach.
The nutrients from the digested food are transported into blood streams by the small intestine, and the swallowed food from the mouth enters the food pipe. The rectum is involved in the elimination of the wastes hence these options are not correct.

The Beadle and Tatum experiments were based on all of the following assumptions except that.
A. supplemented media permit growth of auxotrophic strains of Nourospora
B. X-irradiation can induce mutations.
C. two strains of auxotrophic Nourospora that grow on minimal medium supplemented with biotin have mutations in the same gene
D. auxotrophs fail to grow on minimal media In their first round of screening. Boodle and Tatum plated spores on minimal medium
Answer: C. two strains of auxotrophic Nourospora that grow on minimal medium supplemented with biotin have mutations in the same gene
Explanation: The Beadle and Tatum experiments had the exception that two strains of auxotrophic Nourospora that grow on minimal medium supplemented with biotin have mutations in the same gene. Thus they played a role in confirming the one gene, one enzyme hypothesis which is the idea that each gene encodes a single enzyme.
While correct but not exact, the hypothesis was confirmed through the use of genetic and biochemical studies of the bread mould Neurospora which were unable to make specific amino acids when mutated as a consequence of a "broken" enzyme needed to build a certain amino acid.
