Why does ice float on liquid water

Answers

Answer 1

Answer: Ice can float on liquid water because the ice is less dense so it has an ability to rise to the top of the glass of water.

Answer 2

Answer: A single water particle (a molecule) is made up of two hydrogen atoms bonded to an oxygen atom. The oxygen will attract the negative charges in the hydrogen towards it. This will cause the oxygen atom to be negatively charged and the hydrogen atoms to become positively charged. When a liquid freezes, liquid particles move closer together and form strong bonds with one another. There are now more particles in the same area, the solid is denser than the liquid. When water freezes the negative charges on the oxygen push the particles apart. This means that the water becomes less dense with freezing.

The enzymatic hydrolysis of sucrose by the enzyme sucrase will result in the formation of its two monosaccharide components, glucose and fructose, as seen in the model above. The activity of an enzyme is affected by many factors including temperature and pH. Each enzyme has an optimum temperature and pH at which its reaction rate is fastest. The optimum pH range for sucrase activity is 4 - 8.Imagine the pH of the environment in which the hydrolysis of sucrose is to occur has dropped to 2. How will this drop in pH influence point D in the model?A)The enzyme (B) will allow less of the substrate (A) to move into the active site (C). B)More of the substrate (A) will fit into the active site (C), so more products will be produced. C)The substrate (A) will no longer fit into the active site (C) because the enzyme has changed shape. D)There will be no change to the components of point D with a drop in pH; only temperature can denature the enzyme.

Why is DNA called semi-comparitive

Answers

DNA is called semi-comparitive because each helix that is created has one strand from the helix which is why it is copied

Hope this helps you know where to fine me ^-^

Because each cell that is created has one strand from the cell it was copied from. The replication of the cell results in two daughter cells which contains one of the origninal parent cells.

What would the climate be like without the greenhouse effect? Back to normal with no threat of global warming
Too cold for many living organisms
Mostly temperate near the equator and extremely cold at the poles
Extremely dry with no moisture in the air

Answers

The correct answer is option B

The temperature could have been too cold for some of the organisms without greenhouse effect.

The average temperature of the earth could have been much lower than what is today.

It is the green house effect that the temperature is optimum for the survival of all the organism otherwise only that organism could have survived who can live at lower temperatures.

it would be to cold cuz

The structures found in a living cell can be compared to the parts of a factory that produces cars. Which part of the factory is the most similar to the nucleus of a living cell?(1) A conveyor belt that transports materials
(2) A storage bin that holds the pieces needed to
assemble the car
(3) The computer room that controls the assembly process
(4) The generator that produces energy for the factory

Answers

The generator that produces energy for the factory. The nucleus serves as the core, the executive branch, and the brain of the cell. The correct option is D.

Thus, It regulates the cell's growth and reproduction and holds the genetic information. The genetic makeup of a cell is contained in the nucleus, which has been explained in detail as a membrane-bound structure.

In addition to serving as a DNA storage space, it also serves as the location of various significant cellular functions. In the nucleus, one's DNA can be duplicated first and foremost. DNA replication is the process that creates an exact duplicate of the DNA.

Cell division begins with the creation of two identical copies of the body or host, with each new cell receiving a unique set of instructions. Second, transcription takes place in the nucleus. Different RNA types are produced by transcription from DNA.

Thus, The generator that produces energy for the factory. The nucleus serves as the core, the executive branch, and the brain of the cell. The correct option is D.

A population of bacteria is treated with an antibiotic. It is estimated that 5,000 live bacteria existed in the sample before treatment. After each day of treatment, 40% of the sample remains alive. Which best describes the graph of the function that represents the number of live bacteria after x days of treatment?A. f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0

B. f(x) = 5000(0.6)x, with a vertical asymptote of x = 0

C. f(x) = 5000(1.4)x, with a horizontal asymptote of y = 0

D. f(x) = 5000(1.6)x, with a vertical asymptote of x = 0

Answers

"f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0" is the one among the following choices given in the question that best describes the graph of the function that represents the number of live bacteria after x days of treatment. The correct option among all the options that are given in the question is the first option or option "A".

Answer:

The correct option is A.

Step by step explanation:

The exponential function is defined as

$f(x)=ab^x$

Where, a is initial value and b is growth factor or decay factor.

The initial population of bacteria is 5000.

After each day of treatment, 40% of the sample remains alive. It means the growth factor or decay factor is

$(40)/(100)=0.4$

Therefore the required function is

$f(x)=5000(0.4)^x$

The horizontal asymptote is y=0 because

$f(x)\rightarrow 0\text{ as }x\rightarrow\infty$

Therefore option A is correct.

What are three ways the atmosphere helps support life on Earth?

Answers

The three ways by which the atmosphere helps support life on Earth are as follows:

It protects the earth from incoming ultraviolet radiation from the sun.
It prevents the excess between the temperatures of day and night.
It delivers the need for oxygen for all living entities.

What is Atmosphere?

An atmosphere may be defined as an envelope of numerous gases that surrounds any celestial body like earth. It is considered the safety armor of the earth that protects living entities with numerous concerns.

The most important function of the atmosphere is to block out the passage of incoming harmful radiations from the sun. It also maintains a balance between the temperature during the day and night significantly.

As the atmosphere is the envelope of numerous gases, it contains one of the most precious gases that furnish life to living beings is oxygen which is utilized by the organisms to accomplish metabolic and cellular activities for their survival.

Therefore, it is well described above.
