Fertilizer grade is the relative ________

An 85 kg object is moving at the constant speed of 15 m/s in a circular path which has a radius of 20meters what centripetal is

yanalaym [24]

Answer: F = M A. Centripetal acceleration = V-squared / R. So F=M V-squared/R. =. 85 x 225 / 20. = <u>956.25 Newton's</u> (about 215 pounds). That's the force required to keep that mass moving at that speed around that circle. If the force is less, or not there, then the 85 kg moves slower, or leaves that path.

How do coral reefs help with climate stability?

DedPeter [7]

The coral reefs help with climate stability because they serve as homes for species that build exoskeletons from carbon.

Carbon in the form of carbon dioxide has been reported to be a major factor in the climate instability of the planet. This is because they are parts of the greenhouse gases that form a blanket layer over the atmosphere and prevent reflected sun rays from escaping back to space.

Thus, greenhouse gases cause the earth's atmosphere to warm up, a phenomenon known as global warming. The warming, in turn, leads to the unpredictability of several climatic factors.

With the majority of the species living in coral reefs helping to make use of carbon dioxide to build their exoskeleton, they are helping to reduce the concentration of the gas in the atmosphere and thereby reducing warming and erratic climatic changes.

Biology help, please!!! 30 points!!

Nina [5.8K]

B): Energy is radiated more than absorbed near the poles

D): Energy is absorbed more than radiated near the equator.

E): Energy is carried from the equator to poles in surface currents.

Explanation:

Thermal energy is a form of energy carried by heat as a result of temperature differences between two places or bodies.

At the equator the sun is overhead and directly bursting energy from space. Areas around the equator have very low albedo because the bulk of radiation is absorbed. The surfaces here are like black bodies.

At the poles, the ice caps and bodies causes the reflection of the bulk of these radiations. Such regions have a very high albedo. Most of the energy here is radiated.

Warm water in the equator due to absorbed energy are rises to the surface and are carried away to the pole.
Colder water moved from the pole towards the equator by deep ocean currents.

Tammy is using a treadmill, and when she puts her hands on the bar, sensors read her heart rate. Today, the sensors are telling

marishachu [46]

<span>The answer for this question is D. Use the machine to increase the incline and intensity. The reason for this is the fact that increasing the incline will cause her to work against gravity and the increase in intensity will result in her having to work harder. The difference between this and her running speed increasing is the fact that mentally she can determine what her running speed is, but if the machine is at an incline and the intensity is set higher, she physically has no choice but to push her body, thus resulting in a more effective workout.</span>

A particular protein largely lacks both secondary and tertiary structure. which factor, if any, is mainly responsible for the re

NemiM [27]

Entropy, is mainly responsible for the resting state of this protein.

Hydrogen bonds, disulfide bonds, and dipole-dipole interactions produce the complicated folding styles seen in secondary and tertiary structure. however, if a protein does not have these elements of structure, it'll undertake a kingdom in which its entropy is maximized.

Secondary shape is determined through hydrogen bonding within the amino acid chain backbone. Tertiary structure is the entire protein's form, decided Entropy Interplay and hydrophobic forces. The tertiary shape of a protein is the 3 dimensional shape of the protein. Disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions all affect the form a protein takes.

The nonpolar amino acids have formed the nonpolar center of the protein, weak van der Waals forces stabilize the protein. furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids make a contribution to the tertiary structure.

Disclaimer: your question is incomplete, please see below for complete question

A. Entropy

B. Hydrogen bonds between amino acid residues

C. Dipole-dipole interactions

D. None of the above
