Answer:
No work was done because the boulder was not displaced.
Explanation:
Even if a person is pushing with a force of 50N and for 10 min, zero work is done and there's no acceleration. Zero work means when the force or displacement on the object is equal to 0 J, and since the boulder never moved it would be 0 J. If the person was pushing with 50 N or even higher and the the object didn't budge, the velocity hasn't changed from rest and that would mean no acceleration occurred.

Use mutation in a sentence
Answer:
A mutation is any change in DNA.
Explanation:
There are plenty of mutations on the world. Some of them are useful.
For example, freckles and red hair are because of a mutation in the MC1R gene.
I hope I didn't hurt your feelings:)
It's a pleasant one. As long as you don't have them all over your face. Or red hair like Anne from Anne from the Green Gables.
If you sleep for only 4 hours, it's also an example of a mutation (sorry I don't know the gene)
6 fingers/toes is an example of a mutation.
I have 5+5fingers and 5+5 toes. And you?
Albinos also have a mutation.

which term describes water that picks up chemicals and pollutants as it moved over driveways, streets, and lawns?
A) septic water
B) runoff water
C) pure water
D) arctic water
Answer:
A or B
Explanation:
a) The term "septic" refers to the anaerobic bacterial environment that develops in the tank that decomposes or mineralizes the waste discharged into the tank.
b) Runoff is nothing more than water "running off" the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
WHAT IS HOMESTASIS???? SOMETHING I CAN UNDERSTAND PLEASE!
Explanation:
Homeostasis, from the Greek words for "same" and "steady," refers to any process that living things use to actively maintain fairly stable conditions necessary for survival. The term was coined in 1930 by the physician Walter Cannon.
Examples include thermoregulation, blood glucose regulation, baroreflex in blood pressure, calcium homeostasis, potassium homeostasis, and osmoregulation.
PROCESS OF HOMEOSTASIS IN THE HUMAN BODY
Homeostasis refers to the body's ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.). ... As the body works to maintain homeostasis, any significant deviation from the normal range will be resisted and homeostasis restored through a process called a feedback loop.
Answer:
Hi there :)
Explanation:
HOMEOSTASIS
A property of cells, tissues, and organisms that allows the maintenance and regulation of the stability and constancy needed to function properly.
- In simple terms, Homeostasis is any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival. If homeostasis is successful, life continues; if it's unsuccessful, it results in a disaster or death of the organism.
Hope it helps :)

Formulate a prediction explaining how a cell may be affected if it does not undergo
cellular transport. (A prediction is in the “If... , then..." format)
If a cell is unable to undergo cellular transport, then the cell will inevitably die.
Cellular transport can be summarized as a series of processes and methods used by cells to transport ions, smaller molecules, and macromolecules like proteins, from one side of the membrane to the other. This can be divided on a large scale into:
Active transportPassive transportbased on whether or not the cell in question needs to invest energy for the transport to happen. Each of these then have many subdivisions to account for the numerous kinds of transports a cell is able to undergo.
Most of the cellular transports that happen in the human body are essential for the life of that cell. The most common and essential cellular transport is the passive transport of water and oxygen through osmosis and diffusion. Water provides the cell with the ability to maintain basic structure and carry out necessary functions. Oxygen is required by all cells to break down sugars in order to obtain energy in the form of ATP. This is done through a process known as cellular respiration. The waste produced by this is carbon dioxide, which in the absence of cellular transport would not be able to leave the cell.
If a cell is unable to undergo cellular transport, then the cell will inevitably die due to it being unable to transport water, oxygen, carbon dioxide, and numerous other ions and molecules that are necessary for the cell to complete even the most basic of functions.

Answer:
A camel's humps are incredibly important for the animal's survival in a tough environment like a desert. Without its humps, a camel would be more likely to overheat and sweat—but it's still the oval-shaped blood cells that help the camel retain so much water, not the humps.
Camels are usually between 6 and 7 feet in height and 9 to 11 feet in length. They can weigh up to 2,300 pounds. Other physical characteristics of camels include long legs, long necks, and a protruding snout with big lips.
