A scientist conducted an investigation about the effects of diet on disease resistance in mice and made surprising observations. The mice with a genetic ear mutation seemed to show similar patterns of resistance compared to mice with normal ears. Based on this information, what will the scientist most likely do next?
Explanation:
When there is alteration in the DNA sequence in the chromosomes of an organisms which affects the protein expression and therefore the organism involved,the genetic condition is called mutation. its effects can be positive or negative,But,negative effects is most common.
It can be germline in which the genes is affected,or somatic in which the protein expression of the body cell is affected.
Answer:
The fact that the mice with genetic mutation shows similar patterns of inheritance show that some genes in the mice might be playing a dominant role in diseases resistance in this animals.This is evident since the patterns were peculiar to mice with mutated ears,and not observed in normal ears.
Therefore the experiment should be carried out again to confirm the influence of these genes on the resistance
Being able to respond to change (irritability) is one of the necessary life functions. Which body system is mostly responsible for this function

Winding mills are made on hills. Why?
Answer:
Winding mills are made on hills because of air flow and currents.
Explanation:
Winding mills capture wind to turn blades and produce energy. In order to do so, it needs winds! Strong winds, in order to turn the blades. You will notice that if you ever scale a mountain or go higher, it starts to become windier/the wind blows harder.
If the wind mills are placed higher, it can capture these windier conditions, thus moving the wind blades to produce energy. The higher the hill, the stronger the wind current, the more energy it produces.

Amino acids is to protein as nucleotides is to nucleic acid.
Thank you
Amino acids is to protein as nucleotides is to nucleic acid.
What is the composition of nucleic acid ?
Nucleic acids are biomolecule major component of cell which carry genetic material, these are up two types of nucleic acid such as deoxy ribose nucleic acid or DNA and ribonucleic acid or RNA.
DNA is the carrier of the genetic material which is passed from the parents to offspring and nucleic acids are composed of the monomers of nucleotides, these nucleotides are composed of nitrogenous base, phosphate and pentose sugar.
The nitrogenous bases are uracil, cytosine, thymine, adenine, and guanine, pentose sugar such as ribose sugar and deoxyribose sugar and phosphate group.
DNA contains thymine instead of uracil which is present in RNA; Adenine and guanine are the purines having double ring structure while the rest are pyrimidines have a single ring structure. The phosphate group is negatively charged.

Which one of the following molecules would be most likely to travel by facilitated diffusion? A. sodium ions B. glucose C. oxygen atoms
Answer:
The correct answer is : the sodium ion and glucose both shows the facilitated diffusion.
Explanation:
Facilitated diffusion is form of diffusion of molecules of solutes with the help of transport proteins along their concentration gradient on the plasma membrane, however it is a passive transport as its does not require energy to move in or out of cell.
Oxygen can move through the membrane directly by simple mean of diffusion. however, Other molecules like amino acids, ions, glucose and many more need a integral pore, channel or transport molecule to pass through the membrane or with facilitated diffusion.
Glucose transporters involves to help in movement of glucose through the membrane along the concentration gradient it shows facilitated diffusion. Sodium ions also move through along concentration gradient by protein channels formed by transport proteins through hydrophobic membrane.
Thus, the sodium ion and glucose both shows the facilitated diffusion.
Answer:
B. Glucose
Explanation:
Facilitated diffusion is important for the living organisms as there are lipid insoluble, polar and large molecules that needs assistance to diffuse across plasma membrane. These molecules are large and polar in nature so they need assistance. The ion channels or carrier proteins allow such molecules ( glucose) to cross the membrane. The two classes of protein that facilitates the diffusion are channel protein and carrier protein.

The _____ was a direct result of the Industrial Revolution.
O improvement in quality of life
O shift to domestic foods over wild foods
O decrease in urban areas
Answer:
Option: Improvement in quality of life
Explanation:
The industrial revolution resulted in a significant improvement in the quality of life for the working class. However, it was slow, irregular, and sometimes missing through many years. The evidence of increasing incomes and improving mortality rates indicate significant improvement took place in the pattern of living of the working class. These factors suggest that the quality of life at least continued firm, and presumably developed. This progress took place with constant warfare with factory owners and government intervention. The Industrial Revolution introduced new machinery, the transformation of cities. The rapid growth of cities and towns beginning to take place with a change in society.

Carrie is conducting an experiment on a solution. The solution's initial pH is 3.2. Then, as Carrie gradually adds Compound X into the solution, the pH increases to 9.8. Which is the most likely identity of Compound X? A. a strong acid, such as hydrochloric acid (HCl) B. a strong base, such as sodium hydroxide (NaOH) C. a salt, such as sodium chloride (NaCl) D. a solvent, such as water (H2O)
Answer:
B
Explanation:
The correct answer would be a strong base, such as sodium hydroxide (NaOH).
The pH of a substance represents the degree of acidity or basicity of the compound. The pH scale ranges from 0 to 14 with 0 being the most acidic, 14 being the most basic, and 7 being a neutral pH. a pH below 7 is acidic and above 7 is basic.
A solution with an initial pH of 3.2 is acidic and in order to raise the pH to 9.8, it will require a strong base. Hence, compound X must be a strong base such as sodium hydroxide.
Correct option: B
Answer:b
Explanation: trust me
