how do cell theory, cells, and organelles link and connect?
PLEASE HELP BY 9/20-9/21/20
Answer: They are all connected .
All living organisms on Earth are divided into cells. The main concept of cell theory is that cells are the basic structural unit for all organisms. Living things may be single-celled or they may be very complex such as a human being. There are smaller pieces that make up cells such as macromolecules and organelles. A mitochondrion is an example of an organelle. If you were only made of one cell, you would be very limited. You don't find single cells that are as large as a cow.
Explanation ; easier so you can understand :)
We are made up of cells . The cell theory is that cells are what we are made of and the other animals and things in the world. Everything is made out of cells. The things that make up cells are orgenelles. That is how they are all linked up. Human > cells > oragenelles.
hope that helped :)
Answer:
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.

What is the difference between aerobic and anaerobic cellular respiration?
Answer: Explanation:
Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.
The main difference between aerobic and anaerobic respiration is that the former takes place in the presence of oxygen while the other is in the absence of oxygen.
Aerobic respiration refers to respiration in the presence of oxygen according to the following equation:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O + 32 ATP[/tex]
While anaerobic respiration refers to respiration in the absence of oxygen according to the following equations:
[tex]C_6H12O6 ---> 2CO_2 + 2C_2H_6O + 2ATP[/tex]
Thus, another difference is that aerobic respiration generates more energy (32 ATP) than anaerobic respiration (2 ATP).

Which type of weather do we associate with low pressure systems? (select all that apply)
a
happy weather
b
clear skies
c
sunny days
d
lousy weather
e
rain
f
clouds
Answer:
F
Explanation:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with large diurnal temperature changes due to greater radiation at night and greater sunshine during the day.

How is the rate of a chemical reaction related to temperature
Answer:
An increase in temperature typically increases the rate of reaction.
Explanation:
An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision

Construct an Explanation Is the importance of an element in the body related to its percentage of body weight? Cite the evidence in the table to support your explanation.
Answer:
The osmosis processes are spontaneous processes in our body, these processes have a high enthalpy, tend to disorder, and it is necessary if or if a permeable or semi-permeable membrane to water between two spaces with different concentrations of solutes.
Explanation:
The osmosis processes occur spontaneously, this means that their onset in the process is natural, an example of this is the edema of the lower limb on hot days, or in inflammatory situations, or the example that was cited with the chicken's egg.
The water that passes through the permeable membrane will always go from the zone with the lowest concentration to the one with the highest concentration, in order to equalize and equalize the concentrations and molarities of the compartments that interact with each other.
2. Describe the property of water that is indicated
by the data. How is this property explained by the
structure of water molecules and the bonds
between them?
Answer:
The correct answer is - high specific heat.
Explanation:
Water atoms are polar, so they structure hydrogen bonds. This gives water remarkable properties, for example, a moderately high specific heat, density, adhesion, and cohesion.
A water particle comprises of two hydrogen iotas clung to an oxygen molecule, and its general structure is bowed. Oxygen even bonding with hydrogen have two sets of unshared electrons. The entirety of the electron pair and unpaired repulse one another.
Water's high specific heat is a property brought about by hydrogen holding among water particles. At the point when warmth is assimilated, hydrogen bonds are broken and water atoms can move uninhibitedly. At the point when the temperature of water diminishes, the hydrogen bonds are shaped and discharge a lot of vitality.
Thus, the correct answer is - high specific heat.
The property of water described by the heating curve is high specific heat capacity.
The specific heat capacity of a substance refers to the quantity of heat required to raise the temperature of 1 Kg of the substance by 1°C. The higher the heat capacity of a body, the greater the quantity of heat required to raise the temperature of 1 Kg of the substance by 1°C.
Looking at the heating curve, we can see that water has a very high heat capacity because a large quantity of heat is required to raise its temperature by 1°C. This is because of strong intermolecular hydrogen bonding between the molecules of water which leads to molecular association and high boiling point.

How are metamorphic rocks formed
Hey friend your ans is here
I hope it will helpful for you
Mark as brainest answer✅
Thank you
Answer:
Metamorphic rocks are formed from other rocks that are changed because of heat or pressure.. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure . They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.
