Aquifers but since there is no answer choice I say groundwater .

Hope this helps .

Water located in wells underground is ground water. Therefore, the correct option is option C.

Water that is found below the earth's surface in cracks in rocks and the crevices between soil particles is known as groundwater. It is essential for maintaining ecosystems on our planet and supporting human activities. Groundwater is created and made available by precipitation and surface water that seeps into the ground. It gathers in subterranean aquifers, which are enormous water reservoirs contained in permeable rocks or sediments. The thickness and depth of these aquifers vary. Groundwater supply is influenced by elements like rainfall, geology, and human use. Groundwater is an important resource since it is necessary for a variety of purposes. It provides over half of the world's population with their main supply of drinking water.

Therefore, the correct option is option C.

eselson and Stahl relied on equilibrium density gradient centrifugation to resolve the DNA containing 14N from the DNA containing 15N.They started off with DNA in media containing the heavy isotope, then switched to media containing the lighter isotope and allowed DNA replication to take place. Under semiconservative model of DNA replication, after THREE rounds of replication, how many bands of DNA would you see and which band would contain more DNA molecules

Answers

Answer:

The correct answer would be - two bands ( one intermediate, and one light)- the light band contains more DNA molecules.

Explanation:

After the switching to the lighter isotope by the second round of replication where light strands are used as template strands, produces the light band of 14N.

After three rounds of semiconservative replication, where template strand contains both heavy and new formed light bands or nitrogen and produces so in a Density gradient, there will be 2 bands one light band and the other intermediate band.

A BISC 220 student went swimming at the Uytengsu Aquatics Center. Having missed an important lecture on the respiratory system, he thought it would be a good idea to hyperventilate for a minute before diving into the pool and swimming vigorously underwater. Shortly after he began swimming, he lost consciousness and would have drowned if not for the quick action of the lifeguard. Which one of the following best describes what happened?
A. Hyperventilation increased the Poz in his blood, which inhibited the brainstem respiratory center.
B. Hyperventilation decreased blood Pco2, which reduced respiratory drive at the same time that exercise increased the demand for O2
C. Skeletal muscle activity caused an increase in blood pH, which suppressed brain function and made him faint.
D. Hyperventilation increased the saturation of hemoglobin with O2, but vigorous exercise caused the bound O2 to be replaced by CO2

Answers

Answer:

B. Hyperventilation decreased blood Pco2, which reduced respiratory drive at the same time that exercise increased the demand for O2.

Explanation:

Hyperventilation is a breathing at an abnormal rate. There is an increased rate of loss of carbon dioxide which causes an increased demand for the oxygen. The respiration process is affected due to hyperventilation.

What do you mean by cellular respiration?

Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.

Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Briefly explain the nature of scientific inquiry. Include discussion of the role that evidence and falsifiability play in the process. Is this a strength or a weakness of the scientific mode of
thinking?

Answers

Answer:

Science is a process that involves proof and error. Scientific hypotheses are used to find evidence supporting scientific statements, but new evidence can be used to reject previously accepted ones in order to get closer to the truth.

Explanation:

Scientific inquiries refer to the processes by which scientists study phenomena of the natural world and propose alternative explanations (hypotheses) useful for understanding such mechanisms. When hypotheses are supported by many evidence and studies from different sources, scientific theories associated with these hypotheses become accepted by the scientific community. In science, a scientific statement may become falsifiable when it is contradicted by new lines of evidence and/or new observations.

Which of the following best describe gas particles?
SELECT ALL THAT APPLY
a moving randomly
b collide into each other
Cmove slow
d high kinetic energy
moving orderly
e moving orderly

Answers

Answer:

a, b, d (see below)

Explanation:

So, looking at the 3 states of matter:

Solid - holds a shape and is made up of particles that vibrate in place (because particles are always moving no matter what)

Liquid - holds shape of its container and has particles with some space in between them that allow them to flow

Gas - holds shape of its container and has particles with huge gaps of space between them that are always, constantly moving and zooming around

Refer to the image below for a better visual understanding.

So, now, looking at the answer choices:

a) moving randomly

Yes. They are—they're speeding around super fast all the time.

Every time heat is added to something, the particles start loosening up and moving. A lot.

So when you add heat to a solid, it starts loosening up and moving around until it becomes flowy enough to be a liquid. Then, if more heat is added, the particles moving faster and loosen up even more until they're a gas.

Imagine doing that one more time, and you'll have plasma. As you may have guessed it, plasma moves super fast

b) collide into each other

Yes. Because they're moving so fast and uncontrollably all the time, they're bound to have rammed into one another a few or more times.

Imagine bumper cars at a carnival, except the speed of each car is sooo fast that you could be on a highway. You're probably going to hit someone, which is why bumper cars are not that fast in reality. For safety reasons.

c) move slow

No. Since we know that they're always zooming around (refer to my bumper car example above, in bold), they obviously can't be slow.

d) high kinetic energy

Yes. Anything moving (a.k.a. in motion) has kinetic energy. If gases zoom super fast 24/7, they will have high kinetic energy.

Having high kinetic energy means that the something is moving really fast or a lot. In this case, gases are both.

e) moving orderly

No. They're moving everywhere and really fast, so they have no control over how they move because of how fast they are.

(refer to my bumper car example in answer b, in bold)

Name two types of proteins that regulate the cell cycle.How do these proteins work?

Answers

Answer:

Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.

Explanation:

Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur while external regulators speed up or slow down the cell cycle.

What are Proteins?

Proteins are large and complex molecules which play many critical roles in the body. Proteins do the work in cells which are required for the structure, function, and regulation of the body's tissues and organs.

Proteins are made up of many smaller units called amino acids, which are linked together in long chains. There are 20 different types of amino acids that can be linked to make a protein.

The sequence of amino acids determines each protein's unique 3-dimensional structure and its specific function. Amino acids are coded for by a combination of three DNA building blocks (nucleotides), which are determined by the sequence of genes.

Thus, internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur while external regulators speed up or slow down the cell cycle.
