Which statement explains why sugar dissolves easily in water, but sand does not? Sugar has a greater buoyant force than sand. Sugar has a greater conductivity than sand. Sugar has a greater hardness than sand. Sugar has a greater solubility than sand.

  • Sugar dissolves easily in water, but sand does not because sugar has greater solubility than sand.
  • A solution is made by mixing a substance (solute) in a medium (solvent). The chemical property of the solute that describes how easily the solute will dissolve in a given solvent is known as its solubility.
  • The greater the solubility of a solute the more easily it dissolves in a solvent.
  • The solubility of different solutes varies from each other and, also varies from one solvent to another.
  • If we compare sugar and sand then sugar has more solubility in water as compared to sand and, is able to dissolve more quickly and easily.

B. The Stomata


The stomata are the pores of the leaves. They allow the exchanges of gas and contain what are called guard cells. These guard cells control the opening and closing. These pores allow for evaporated water to be released and carbon-dioxide to be collected.

Humans cannot digest food without the aid of small single-celled organisms that live in our digestive tract. These small organisms help humans digest food by breaking down complex food molecules. Which common name is associated with these single-celled organisms that help humans digest food? A) algae B) bacteria C) protozoa D) virus

Bacteria are single-celled organisms that help humans digest food.

Explanation:

The symbiotic association of bacteria and human is of importance in the process of digestion. These bacterias are found in our gut, large intestine and sometimes in small intestine also. These bacteria break down big molecules into useful forms. Bacteria are also responsible for producing vitamin k2 and vitamin B in large intestine. They also help in mobilising of xenobiotics, bile and sterols.

QUESTION POSTED AT 23/02/2020 - 11:32 PM

18. In a species of wild animal, claw size is determined by a combination of two alleles. Allele Q codes for large claws, while allele q codes for small claws. Individuals with a heterozygous genotype possess claws of medium size. Members of the species depend on their claws to be able to burrow in the ground and find food. But in an area where the ground has always been soft, gradual climate change has caused the dirt to become hard and compact. Which statement best predicts the change that will occur in the affected populations? A. Allele q will decrease in frequency. B. Allele q will become dominant to allele Q. C. Allele Q will become dominant to allele q. D. Allele Q will decrease in frequency.

Answer: The correct answer is- A) Allele q will decrease in frequency.

According to the information in the question, allele Q codes for large claws and allele q codes for small claws in a species of wild animal.

This indicates that larger claws will enable the wild animals to burrow more in the ground and find their food. As the change in the climatic conditions caused the dirt on the ground to become hard and compact.

This will result in change in the frequency of allele of the population as allele Q will increase because larger claws will provide more advantage (in context of burrowing) to the animals for getting their food, whereas frequency of q allele will decrease ( as smaller size of claws will not be that beneficial to them in hard and compact ground).

Thus, option A) is the right answer.

Answer;

-Change in a population through genetic variation over time.

Explanation;

-Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. It is the process of genetic change from one generation to the next and may be caused by several aspects including mutation, natural selection, genetic drift, thought and technology.

Which major change can occur in a small population that is the result of the genetic drift? A. recessive traits always become dominant B. new individuals add their genes to the gene pool C. large changes in allele frequencies can occur in a short time.

The answer is C. large changes in allele frequencies can occur in a short time.

Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.

The answer is D.

Dinosaurs with feathers could not fly. This was because their arms were too short, and their bodies too fat. Some dinosaurs could fly (Pteradon, Quetz, etc.) but they did not use feathers, they had skin-like flaps between their arms that allowed flight.

Answer:

B. The production of proteins based on the genetic information in DNA

Explanation:

    Gene expression is the set of processes by which information contained in genes is converted into molecules that determine cell properties, that is, the transfer of genetic information from DNA to protein.

    The expression of a gene encompasses a series of steps ranging from the synthesis of an RNA molecule, from a base sequence in the DNA molecule (gene) to the synthesis of a protein from that RNA molecule (messenger RNA).

Answer: Water can enter to the atmosphere thanks to evaporation. This is the process in which water goes from liquid to gas state.

Water have to be in gas state to enter in the atmosphere since it is the outer layer of earth made of gases which are lighter or have low density compared to other components of earth. Atmosphere is essential for life on earth because it isolates uv rays from sun.

If you were stranded on the ocean in a raft, what would happen if you kept drinking ocean water? your blood would become hypotonic your blood would become hypertonic the concentration of water in your blood would increase the concentration of water in your blood would decrease water would flow out of your body cells the excess water would flow into your cells

The correct answer is that water will flow out of the cells of the body.  

When one consumes salt water, the concentration of solutes external to the cells will enhance making the water inside the cell to move out of the cells, thus, making the cells shrink. Outside the cell, the solution is hypertonic and may result in dehydration.  

The kidneys in human can only produce urine, which is less salty in comparison to salt water. Thus, to withdraw all the extra salt consumed, one has to urinate more water than one has drunk. Hence, resulting in dehydration.

Atomic bombs send out a shock wave when they are detonated. This occurs because the bomb’s detonation superheats the air particles nearby, which cause them to bump into other air particles that further the wave. Which statement can most likely be made about the shock waves of atomic bombs? A.They are a mechanical waves. B.They are an electromagnetic waves. C.They will act like x-rays. D.They will act like light rays

Answer:

Option A, They are a mechanical waves.

Explanation:

All mechanical waves such as sound waves, seismic waves, shock waves, gravity waves etc. require some sort of medium for transmission. For instance seismic waves uses underground earth as a medium, sound waves uses water, air etc. as a medium likewise shock waves also need some medium. In the question it is mentioned that shock waves are travelling by bumping onto air particles. Air is also a kind of medium of transmission and hence, shock waves are also mechanical waves.

Thus, option A is correct
