Answer:
Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.
That light energy will be absorbed and converted to heat. Then it will radiate out into space as infrared thermal radiation. It will travel in that form for a long time, once it gets out of the Earth's atmosphere.

What drives surface currents?
differences in air temperature
differences in climate
differences in water density
differences in water salinity
Answer:
WHAT DRIVES SURFACE CURRENTS?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
DIFFERENCES IN AIR TEMPERATURE.
Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.
DIFFERENCES IN CLIMATE.
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
DIFFERENCES IN WATER DENSITY.
High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.
DIFFERENCES IN WATER SALINITY.
As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.

Collagen has: Group of answer choices pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable). rings of glycine, which can stabilize helices and proline residues at every third position (because only proline residues can fit inside of the super-helical cable). rings of proline and glycine residues at every second position. pyrrolidine rings, which can push off and destabilize the helix and glycine residues at every second position (because only glycine residues can fit inside of the super-helical cable).
Collagen has: A. pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable).
Collagen can be defined as the main or most abundant structural protein found in the bones, tendons, connective tissues, skin and muscles of a living organism such as a human being.
Basically, collagen is a chemical substance (protein) made up of amino-acids and it holds the human body together.
Hence, collagen typically makes up about 30% of the proteins contained within the human body.
Additionally, collagen comprises the following specific amino-acids:
Hydroxyproline.Glycine.Arginine.Proline.Each of the three chains of a collagen triple helix with 3.3 residues per turn, is normally stabilized by the steric repulsion between the pyrrolidine rings of hydroxyproline, glycine and proline residues.
Therefore, the pyrrolidine rings of collagen helps in the stabilization of helices and glycine residues, at every third position because the only residue that fits inside of the super-helical cable is the glycine residues.

Astrologers relate the location of the stars and planets to events in human lives. Many years ago,people classified astrology as a science. Why do modern scientists consider astrology to be a pseudoscience?
Answer:
C.
Explanation:
yes, astrology doesn't offer conclusive proof of its claims. astrologers predict the future with the location of planets and stars but they don't have a concrete theory that the location of a particular planet has an impact on human life. they believe in something called universal energy.

Which process must occur for a muscle to be able to relax?
A. A nerve must initiate an action potential in the muscle fiber.
B. The amount of ATP in the neuromuscular junction must increase.
C. The concentration of calcium in the myofibril must decrease.
D. Myosin and actin must attach to each other.
Answer: C. The concentration of calcium in the myofibril must decrease.
I hope this helps.
Answer:
c
Explanation:
Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax.

In the Bird Beak Gizmo, how did the bird beak depth change in drought conditions?
O No change
O Beaks got shorter beacuse the birds had to scrape more to find seeds.
Beaks got longer because the only birds that survived had larger beaks that could crack the hard seeds
Answer:
I think it would be #3, Beaks got longer because the only birds that survived had larger beaks that could crack the hard seeds
Explanation:
In years of extreme drought, the small, delicate seeds get eaten up quickly, leaving behind only the largest, toughest seeds.

How do your sensory organs help you to maintain homeostasis?
Answer:
Hi
Explanation:
“Sensory cues influence homeostasis by modulating hormone secretion. ... In step 1, sensory cues change the activity of sensory neurons. In step 2, the sensory information is processed and transmitted, which leads to step 3, where neuro- or nonneuronal endocrine cells secrete hormones required in maintaining homeostasis.”
the tensor fascia latae is involved in hip __________.
Answer:
Abductor Muscle.
Explanation:
The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).

in the figure, which number represents dna synthesis?
The number that represents DNA synthesis in the figure would be II.
DNA synthesis happens at the S phase in the interphase of the cell cycle, just after the G1 or cell growth phase and before the G2 or protein synthesis phase.
During the S phase, the amount of DNA in the cell doubles as replication of DNA takes place. However, the number of chromosomes remains constant.
The doubling of the amount of DNA is responsible for the sharp rise in the line that represents the amount of DNA in the figure. Thus, the region of a steep rise in the amount of DNA would represent the DNA synthesis phase.

red-green colorblindeness occurs more commonly in men than it does in women. using this information, which chromosome do you suppose the gene for red-green colorblindness resides on, and is the trait dominant or recessive?
Answer:
Usually the Y chromosome. It is recessive because if one Y chromosone is mutated with red-green colorblindness and the X is not, the child will have colorblindness. But, if one X chromosome has the mutation and the other X does not, they will cancel out, meaning the child will not have colorblindness.
