Answer:
Blood cells are responsible for constant maintenance and immune protection of every cell type of the body. This relentless and brutal work requires that blood cells, along with skin cells, have the greatest powers of self-renewal of any adult tissue.
The stem cells that form blood and immune cells are known as hematopoietic stem cells (HSCs). They are ultimately responsible for the constant renewal of blood—the production of billions of new blood cells each day. Physicians and basic researchers have known and capitalized on this fact for more than 50 years in treating many diseases. The first evidence and definition of blood-forming stem cells came from studies of people exposed to lethal doses of radiation in 1945.

1. You and Tim, who is larger than you are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull
it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating
from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force
that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon
when it had the greatest acceleration during start up? Why? Use Newton's second law to explain.
2. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls
with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton's second law.
Answer:
2. Sarah
Explanation:
because she is stronger, she is able to pull faster and easier because of the amount of weight she can carry vs the amount of weight you can carry. Although you are the same height, she has more muscle.

How are atoms and electromagnetism related?
Explanation:Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. ... These electrons in these atoms are then in a high energy state.

This shows that in 2018 the number of nests increased while the number of eggs per nest increased at the minimum and decreased at the maximum when compared to 1780. We can see that by looking at the graph. The blue curve represents 2018 and the dotted 1780. The Y-axis represents the number of nests while the X-axis represents the number of eggs. The dotted one is shorter but wider and the blue one is taller.
If you are working out and your oxygen supply is not meeting the demands of your cells, what process will your cells undergo?
Answer:
Fermentation
Explanation:
But when you sprint, your lungs and bloodstream can't supply oxygen fast enough to meet your muscles' need for ATP. In such situations, your muscle cells use another process, called fermentation, that makes ATP without using oxygen.
What “rule” or reasoning did you use to decide if something is a rock?
Answer: Anything that has an Origin, composition, and texture.
Explanation:
May be Minerals, feel rough or smooth, and can be hundreds or thousands of years old.
A rock is a naturally occurring compound which is made up of one or more minerals. They are found in the Earth's crust which undergoes transformation with the changing environmental conditions.
What qualities define a rock?
A rock can be defined as a solid mass of geological materials. The geological materials include individual mineral crystals, inorganic non-mineral solids such as glass, pieces broken from other types of rocks, and even the fossils.
The physical properties of rock include density, porosity, and permeability, etc. The mechanical properties of rock mainly include the elastic modulus, Poisson's ratio, and its strength. These parameters can be obtained through the laboratory experiments of core samples or by the in-situ tests.
A rock is a naturally occurring group or compound of one or more minerals that stays together. A rock is anything which has an origin, composition, and a texture.

I need help with this question somebody answer!!
Answer:
The essential factor to increase the number of cells in a growing organism is that each and every cell has a complete copy of DNA.
Explanation:
The development and growth of an organism is based on the multiplication of its tissue cells. Cell multiplication in somatic cells occurs through mitosis, a process that allows obtaining two identical daughter cells from a progenitor cell.
DNA contains all the genetic information belonging to a living organism. In the process of mitosis, the DNA of each cell must be replicated so that each daughter cell has a complete copy of the original DNA. This ensures that each cell resulting from mitosis has the same structure and function as the original cell.
The other options are not correct because:
The size of the cell is important, since each cell has defined characteristics, according to the tissue it must form. Each and every cell needs to have a complete DNA. In somatic cells, DNA does not vary from one cell to another.Briefly describe what happens in Telophase 1

Shoot the Golgi Apparatus. Fill in the blanks: Golgi receives ANSWER containing ANSWER that were sent by the ANSWER Then it modifies ANSWER and send them where they need to go.
Answer:
Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.
Explanation:
Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are packaged into vesicles and sent to the Golgi complex, where it occurs the final association of carbohydrates with proteins. The Golgi complex sends proteins to their different destinies. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.

Carbon dioxide is used by plankton during photosynthesis to make organic molecules containing ( lead / carbon / argon / chlorine )
Answer:
Carbon
Explanation:
Photosynthesis is a process carried out by the cells of autotrophic organisms in order to synthesize their own food in form of sugars (glucose). As rightly stated in this question, Carbon dioxide (CO2) is a major ingredient for this process to occur. Inorganic CO2 enters an organism like plankton and is used to make organic molecules.
The organic molecules produced via the photosynthetic process are in form of sugar (glucose) i.e. C6H12O6 whose principal elemental component is CARBON. In other words, the organic molecules contain carbon in their structure, got from the CO2 source.

Answer:
The answer is F.
Explanation:
The reason why is the Mitochondria converts glucose to energy. If it were to be removed, protein production would stop, normal functions would cease, homeostasis would be off balance. also because activities going towards the Nucleus. No control center, no protein production since ribosomes are made there. Thus, destroying that cell completely.

After the enzyme and substrate bind together and perform the reaction, what does the substrate become?
Answer:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process.
After the enzyme and substrate bind together and perform the reaction, the substrate becomes a PRODUCT of that chemical reaction.
Enzymes are biological catalysts that bind specific substrates to speed up the rate of a given chemical reaction. Substrates are molecules upon which the enzymes act.Products are molecules formed from chemical reactions.Enzymes function by lowering the energy of activation of different chemical reactions.In conclusion, after the enzyme and substrate bind together and perform the reaction, the substrate becomes a PRODUCT of that chemical reaction.
