Answer:

“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”

Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.  

Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular structures called cell organelles are suspended in the cytoplasm.

Prokaryotic cells have no nucleus. Instead, some prokaryotes such as bacteria have a region within the cell where the genetic material is freely suspended. This region is called the nucleoid.

They all are single-celled microorganisms. Examples include archaea, bacteria, and cyanobacteria.

The cell size ranges from 0.1 to 0.5 µm in diameter.

the hereditary material can either be DNA or RNA.

Prokaryotes reproduce by binary fission, a form of sexual reproduction.

Eukaryotic cells are characterised by a true nucleus.

The size of the cells ranges between 10–100 µm in diameter.

This broad category involves plants, fungi, protozoans, and animals.

The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cells. It is also responsible for cell to cell communication.

They reproduce sexually as well as asexually.

There are some contrasting features between plant and animal cells. For eg., the plant cell contains chloroplast, central vacuoles, and other plastids, whereas the animal cells do not.

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.

Any solvent can undergo the process of osmosis including gases and supercritical liquids.

An isotonic solution: is one that has the same concentration of solutes both inside and outside the cell.

A hypertonic solution: is one that has a higher solute concentration outside the cell than inside.

A hypotonic solution; is the one that has a higher solute concentration inside the cell than outside.

Osmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.

An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.

The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure

Answer: The nucleus.

Explanation: In an atom, there are two main parts, the nucleus and the electron cloud/electron shells. The protons and neutrons are located in the nucleus, and the electrons are located in the electron shells/cloud/whatever.

Answer:

A.

Explanation:

When a power plant is made they all have these pies that come out of the buildings to extract the smoke but what most people don't know is that smoke is put out in the air and is taken to the clouds which mixes with the rain and since it is toxic it eventually leads it to be acid rain the more smog it picks up. Acid rain is very dangerous it burn down a whole forest, so yes, your answer is A.  

Hope this helps :)

When coal is burned in a power plant for electricity in one city, it might significantly affect a forest that is located many miles away by contributing to acid rain falling on the forest. Thus, the correct option for this question is A.

The disadvantages of burning coal are as follows:

According to the context of this question, when coal is burning, it deposited a high amount of carbon dioxide in the environment due to which carbonic acid is produced which is fallen on the earth along with precipitation. It causes a severe threat to all forms of living organisms in each ecosystem.

Therefore, the correct option for this question is A.

Answer:

Millions in the tri-state area lost power during the height of Superstorm Sandy on October 29, 2012.

Answer:

The correct answer would be - GG and gg.

Explanation:

As it is given that all the 1000 offspring having the same allele Gg which is only possible in one condition that is cross between GG and gg because it is a heterozygous condition in the offspring. So there must be both allele present and it can not be heterozygous parents as there would be a different combinations of offspring in that case.

If the parents either GG only all the offspring would be GG the same with gg than all the offspring will be gg, thus the correct answer would be GG and gg.

Answer:

Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.

Explanation:

An igneous rock is a rock that has been created via cooling of magma.

A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.

A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.

Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.

There are two ways for a rock to become metamorphic under extreme pressure or extreme heat. and there are two types of metamorphic rocks, contact metamorphism and regional metamorphism.

Those mean pretty much exactly what they say.

chemical reaction- The process by which atoms of one or more reactants are rearranged to form different products is called chemical reaction.

         as example a figure is provided below.

so the answer is Atoms of the reactants which changes in a chemical reaction.

Answer:

Stay the Same, Increase, Decrease

Explanation:

Glycolysis produces pyruvate which is functioning normally if only the ETC (electron transport) stopped working because the ETC happens AFTER glycolysis, hence pyruvate is being produced and used at a normal rate (no change). NADH is produced in the cellular respiration stage PRIOR to the ETC so it is being created at a normal (or average) rate, however, it is not being used and split properly (meaning, not enough) in the ETC stage hence it's concentration increases. H+ decreases because it cannot be made if the prior step(s) were not complete.

What would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:

Conclusively, we can therefore say that what would happen to the concentrations of pyruvate, NADH and intermembrane H+ if the ETC stopped working are:

Explanation:

Answer:

The correct option is Polar

Explanation:

The polar region/arctic are located/extend from 66.5 degrees N (north) and also S (south) latitude to the north and south poles of the earth. From this, it can be deduced that the polar region is located between 60-90 degrees of N and 60-90 degrees of S.  Polar regions are far from the equator as a result of this and are characterized by very low solar radiation.

Polar or artic region is located between the coordinates 60-90N and 60-90S. The polar regions are extremely far away from the equator, which is situated at 0-degrees latitude.

The correct answer is:

Option B. Polar

The polar region is defined as the region situated 60-degrees north or south of the equator. The solar radiation in the polar region ranges from only 18 hours and 5 hours during winters.

The middle latitudes are situated between 30N and 30S of the equator. It is characterized by moderate sunlight.

Tropics or tropical rainforests are situated near the equator and usually experience a warm climate.

Therefore, option B is correct.

Stem cell term applies to muscle cells.

Stem cells are the cells that develop into blood, brain, bones, and all of the body's organs. They have the potential to repair, restore, replace, and regenerate cells, and could possibly be used to treat many medical conditions and diseases.

While they can regenerate themselves in an animal or person they are generally very difficult to grow and to expand in the laboratory. Because of this, it is difficult to obtain sufficient numbers of many adult stem cell types for study and clinical use.

Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.
