Answer:
The major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation. DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
Have a great day friend! :D
Answer:
RNA uses predominantly uracil instead of thymine present in DNA.
Explanation:
That’s what RNA has that DNA doesn’t.
Having hair is a(n) _________ trait among mammals.
Answer:
Derived trait
Explanation:
An ancestral (or primitive) trait/character is a feature inherited from the common ancestor of the species/group of interest, while derived traits are those that were absent in the last common ancestor of the group of interest. For example, considering mammals as the target group, the presence of hair is a shared derived trait relative to other vertebrates, i.e., amphibians, reptiles, and birds. However, this trait (hair) is ancestral for humans since the genetically closest species to humans (e.g., chimpanzees) also have hair.

1. Based on your observations, is it possible that bacteria can thrive in
a sealed can and cause vegetables to spoil?
Answer:
Explanation:
When bacteria and other nasty pathogens are heated beyond a certain temperature (usually the boiling point of water – 212 degrees Fahrenheit), they are neutralized or killed. Since the can is sealed before this heating process occurs, no additional bacteria or spores can make it into the can.

The breaking of a large organic molecule into smaller individual subunits involves multiple ________. dehydration synthesis reactions osmotic reactions hydrolysis reactions hydrosynthetic reactions
Answer:
hydrolysis reaction
Explanation:
Hydrolysis reactions are the reverse of condensation reactions. In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro" = water and "lysis" = break) involves adding water to one large molecule to break it into multiple smaller molecules.

If you look at the units for each graph, the lines are both going up 1 and over 1, so this means their slopes are the same.The y-intercept of y[x] is 0, because if you look at the first graph, that's where both lines intercept the y-axis.The second function's y-intercept is in fact -3 because, that's where those lines intercept the y-axis.Hope this helps you :)
Hair is largely made up of the protein keratin. Why can a shampoo containing protein not replace the protein in damaged hair
Given what we know about the protein composition of hair, the protein in shampoo cannot replace the protein in damaged hair due to the fact that it would not be giving the cells the raw material needed to create the protein.
In the human body, along with all other living things, proteins are created from amino acids. The genetic code is read using a strand of messenger RNA called mRNA. Then, a transfer version of this known as tRNA brings the corresponding amino acid based on the genetic code found in the message. These amino acids are then chained together to form proteins.
The protein in shampoo cannot replace the protein in damaged hair because cells do not use entire proteins as a substrate, they use amino acids to create proteins. This may seem counterintuitive, but there are very good biological mechanisms behind it. In order for a shampoo to fix damaged hair, it must contain the amino acids necessary to re-create the lost proteins.

1. How would you describe the movement of the sun over 30 minutes?
Answer:
The earth rotates from west to east. The sun does not move around the earth in 30 minutes. The sun is seen in a different part of the sky, but this is due to the rotation of the Earth. The intensity of light and heat changes as the Earth rotates.The speed of the sun changes the angle of the sky in 30 minutes, it is always moving from east to west, so in 30 minutes it will move further west, no matter what time you experiment.Have an amazing day friend! :D

What does the graph tell you about the concentration of salt inside the cell?
Answer:
So,
Assuming that the plasma membrane is either semipermeable or fully permeable, either diffusion or osmosis will even out the concentration eventually. Therefore, options A and B are eliminated.
The only options left both say that osmosis will take place. We know that osmosis will always move the solvent from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell). Thus, water will move into the cell through osmosis. That is option C.
If the cell cannot get rid of the water quickly enough, the cell will explode by cytolysis.

Generalized global air circulation and precipitation patterns are caused by ________.
A. solar radiation that warms moist air masses near the equator, which then cool and release precipitation as they rise, and then, at high altitude, move north or south of the tropics and sink back to the surface as dry air masses
B. air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas
C. polar, cool, moist, high-pressure air masses from the poles that move along the surface, releasing precipitation along the way to the equator, where they are heated and dried
D. solar radiation that warms dry air masses at the poles, causing them to sink toward the tropics, gain moisture, and then release it as precipitation.
Answer:
option B is the right answer
Generalized global air circulation and precipitation patterns are caused by air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas. The correct option is B.
What is differential heating?The reason we have different weather patterns, jet streams, deserts, and prevailing winds is due to global atmospheric circulation caused by the rotation of the Earth and the amount of heat received by different parts of the globe.
The earth's polar regions are both cold, owing to the fact that they receive far less solar radiation than the tropics and mid-latitudes.
Air masses that are dried and heated over continental areas cause generalized global air circulation and precipitation patterns.
This is then rise, cool aloft, as well as descend over oceanic areas, accompanied by a return flow of humid air from ocean to land, achieving higher amounts of precipitation to coastal areas.
Thus, the correct option is B.

At a fair or circus, some performers and clowns take long balloons and fold them into animals and objects as toys for children. Which statement explains why the balloon can fold, twist, and bend without bursting?
A. There is no matter that exists inside a balloon, so there is nothing that can cause the balloon to burst when it is folded, twisted, and bent.
B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
C. The balloon is made of a flexible material so it can be changed into different shapes without ever bursting.
D. The balloon is filled with air, which is a mix of gases. The pressure of the air inside the balloon makes it rigid enough to look like an animal.
Good Luck :D ! Subject: Science
The statement which explains why a balloon can fold, twist, and bend without bursting is: B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
A balloon can be defined as a flexible rubber bag that can be inflated with a gas such as air.
Generally, air can be trapped in a balloon by sealing its neck tightly.
Hence, this makes it possible for performers and clowns to fold, twist, and bend an inflated balloon into animals and objects as toys for children.
A inflated balloon can be folded without it bursting simply because air is fluid and as such, it would move around the inside of the balloon as it is folded.
In conclusion, air, which is a mixture of gases would move around the inside of the balloon as it is folded because it is also a fluid.
