B is the answer
muscle cells are usually long and have many fibers that can contract and relax.
I'm 100% sure about my answer because I just learned about it :)
The aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.
What is muscle cell?Muscle cell is defined as a unique animal cell that can shrink in size by utilizing a number of motor proteins that have been strategically placed inside the cell.
The cells that make up muscle tissue have the unique capacity to shorten or contract to cause movement of the bodily components.
There are three types of muscle cells.
Cardiac muscleSmooth muscleSkeletal muscleProtein filaments found in muscle cells slide across one another to create muscular contraction.
The configuration of these filaments gives skeletal and cardiac muscle their banded look.
They have a large number of mature mitochondria that supply the energy for muscular contraction.
Thus, the aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.

Atoms with full valence electron shells are chemically stable. Most noble gases have eight valence electrons. So, one model for chemical bonding is the octet rule. This states that atoms will _________ or __________ electrons in order to reach the more stable arrangement of eight electrons in their valence shells. A) lose, gain B) conduct, share C) transfer, share D) conduct, transfer
Answer:
A - Gain or Lose
Explanation:
Atoms with full valency electron shell are usually very stable. Most noble gases with full valency shell are usually very stable . The valency electron are fully occupied(8) for all noble gases this is what makes them hard to react with other element.
During chemical bonding elements strife to attain the octet rule. The octet rule is to have a full valency electron through bonding . When this atom bond they either transfer electron or share electrons.
The case of transferring electrons forms an ionic bonding. One atom gain electrons while the other lose electrons during ionic bonding. One atom form cation while the other forms anions.
For covalent bonding atoms are shared to attain the octet rule. This kind of bonding exist between a non metal and another non metals
Answer:
Explanation:A: gain or lose

HELP PLEASE!!!explain how Earth is heated through conduction
As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.
It must be known that conduction happens mostly near the earth's surface.
Answer:
Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.

energy. What did the wise wizard mean?
Answer: in humans, we don't use light energy to make ATP but in plants however, they create ATP in a proccess called photosynthesis, this process requires light to be absorbed twice, once in each photosystem, and it makes ATP. In fact, it's called photophosphorylation because it involves using light energy (photo) to make ATP from ADP (phosphorylation)

Explain how a lack of carbohydrates will impact cellular functions and why?
Answer:
Carbohydrates they say is the major classes of food and don't forget they are stored by stach in the body and gives your body energy
Carbohydrates are degraded into sugar which, as a primary source, is required for the brain, muscles and other parts of the human body to function normally.
When you don't get enough carbohydrates, the level of sugar in your blood may drop to below the normal range (70-99 mg/dL), causing hypoglycemia.

Explanation:
Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty and take a drink of seawater (3.5% salt). What do you think happens to your stomach cells (1% salt), and why?
Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.
Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.
The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.
However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.
