Which of these statements about ocean water is always correct?
a.) Its area is less than the area of freshwater.
b.)Its salinity is less than the salinity of freshwater.
c.) Its density is greater than the density of freshwater.
d.)Its temperature is greater than the temperature of freshwater.
Answer:
c.) Its density is greater than the density of freshwater.Explanation:
Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume.
The freezing point of seawater decreases as salt concentration increases.
Answer:
C.) Its density is greater than the density of freshwater.
Explanation:
Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases.

Vesícula e vacúolo são a mesma coisa ?
Answer:
Vesículas e vacúolos são sacos ligados à membrana que funcionam no armazenamento e transporte. Os vacúolos são um pouco maiores do que as vesículas, e a membrana de um vacúolo não se funde com as membranas de outros componentes celulares. As vesículas podem se fundir com outras membranas dentro do sistema celular
In a flower, red is dominant to white. If two
white flowers are crossed, what are the
chances that any of the offspring will be red?
Answer:
The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. This situation occurs due to the blending of both the alleles

Two distinct bands appear in a single lane at the completion of an SDS-PAGE analysis of an unknown protein. Select one: a. These bands represent two subunits of a homodimer. b. Each band represents a different sized subunit of a multimeric protein. c. Each band represents a protein subunit with different charge to mass ratio. d. These bands represent two subunits of a heterodimer. e. These bands represent two separate subunits of identical size.
Answer:
b. Each band represents a different-sized subunit of a multimeric protein.
Explanation:
SDS-PAGE analysis allows the separation and discrimination of proteins according to their molecular weight. The technique separates proteins in an electromagnetic field.
The SDS-PAGE technique makes proteins move in solid support -gel- by the action of the electric field. The distance reached by each protein is proportional to their molecular weight. The protein separation from a mixture results in bands that reflect their size.
SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be. The speed of displacement in the electromagnetic field is inversely proportional to the protein size.
What is the reason water has so many special properties?
Answer: Water has many unusual properties
Explanation: Water has many unusual properties because of its polar covalent bonds. Oxygen has a larger electronegativity than hydrogen, so the electron pairs are pulled in closer to the oxygen atom, giving it a partial negative charge. Subsequently, both of the hydrogen atoms take on a partial positive charge.

As a responsible student, what practical thing can you do to contribute to the global effort against global warming?
a. using plastic cups in experiments
b. using a car instead of a bike to go to school
c. turning the lights off when not in use
d. washing clothes only in the afternoon
e. taking a shower only in the morning
Answer:
Its B(and c if it you could answer 2 )
Explanation:
a. Sure your using plastic less but still you could have avoided the use of cups in all.
b. (we already know this is the answer but let me explain) If you use a car of course it would pollute the air so if you use a bike you would both be exercising and polluting the air less.
c. It would cocerve energy so the main reason i asked if it was multi answer.
d.what would that do, your still using water?

How is the temperature range on Earth affected by Earth's atmosphere?
Answer:
Temperature of atmosphere: The Earth's temperature range in Fahrenheit is from 2,700 degrees Fahrenheit (1,500 degrees Celsius) in the uppermost atmosphere to a global average temperature of around 59 degrees Fahrenheit (15 degrees Celsius) near the surface.
A mutation in the gene coding for a single-polypeptide enzyme results in the substitution of the amino acid serine, which has a polar R group, by the amino acid phenylalanine, which has a nonpolar R group. When researchers test the catalysis of the normal enzyme and the mutated enzyme, they find that the mutated enzyme has much lower activity than the normal enzyme does. Which of the following most likely explains how the amino acid substitution has resulted in decreased catalytic activity by the mutated enzyme?
A The substitution decreased the mass of the enzyme so that the mutated enzyme binds more weakly to the substrate than the normal enzyme does.
B The substitution altered the secondary and tertiary structure of the enzyme so that the mutated enzyme folds into a different shape than the normal enzyme does.
C The substitution caused many copies of the mutated enzyme to cluster together and compete for substrate to bind.
D The substitution caused the directionality of the enzyme to change such that the amino terminus of the normal enzyme has become the carboxy terminus of the mutated enzyme.
Answer:
Bats have few natural predators -- disease is one of the biggest threat. Owls, hawks and snakes eat bats, but that’s nothing compared to the millions of bats dying from White-Nose Syndrome. The disease -- named for a white fungus on the muzzle and wings of bats -- affects hibernating bats and has been detected in 33 states and seven Canadian provinces. More than 6.5 million bats have died so far from White-Nose Syndrome. Scientists are working to understand the disease. You can help -- avoid places where bats are hibernating, and if you do go underground, decontaminate your clothing, footwear and gear.

What would be the immediate consequence if a neurons sodium-potassium pump was disrupted?
Answer:
Option A.
Explanation:
The sodium pump in the neuron is electrogenic,there are three Na+ from every K+ that enter the cell . If there is a blockage to all sodium pump activity in a cell, there would be an instant change in the membrane potential which will not allow the action potential to take place because a hyperpolarizing current was removed, which means that the membrane potential becomes less negative. Therefore the electrogenic contribution of the sodium pump to the membrane potential will be small which lead to small depolarization.
how would blockage of the pancreatic duct affect the digestive system
a) The food in the small intestine would be more basic (alkaline
b) It would have little effect because liver enzymes would take over
c) The small intestine would contain acidic, mostly undigested chyme.
d) The stomach would be unable to function
Answer:
D
Explanation:
The stomach would eventually shut down (stop working) cause it could not digest anymore

Which of the following best describes the connection between cardiovascular disease and age?
Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known.
Research this issue, and summarize what’s known so far. In your summary, include information about the energy of radio waves. Be sure to only use credible sources. Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
Answer: Yes.
Explanation: Because if it causes disease or problem then why continue to do it?
Answer: Well, from what my research is saying. cell phones emit low levels of non-ionizing radiation when in use. It can also referred to as radio frequency (RF) energy. And as stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. So, it has not been proven weather or not you could get a tumor or cancer from the energy waves.
Some information about a radio wave is that we can have an energy of around 4 x 10-10 eV.
Okay so, I do think people should limit their cell phone use for other reasons. For one, Phones can be overly addicting, I do speak from experience. Phones can also take up way to much of your time is you're just scrolling around on them.
Explanation: So at least that's what I would say. Hope this helped! :)
