The giant impact theory — the idea that a catastrophic collision about 4.5 billion years ago between Earth and a protoplanet about half Earth's size created a disk of molten rock, gas and debris that consolidated to form the moon — was first set forth in the mid-1970s.
The most normally invoked grounds for lunar formation maintain that a giant protoplanet is sometimes called Theia.
What is lunar formation?
When the Chemical differentiation and crystallization delivered dense material that sank to the bottom of the lunar magma ocean and a spirited crust that created the lunar highlands.
The numerous commonly invoked justification for lunar formation holds that a giant protoplanet, sometimes called Theia, struck the recently formed Earth 4.5 billion years heretofore and formed a cloud of debris that fast coalesced into the moon.
But that hypothesis has mourned from a nagging flaw. Simulations of moon-forming crashes have shown Theia would have stood as the immediate donor of lunar material.
But commentaries of Apollo moon rocks have authenticated that the moon appears in many ways a chemical clone of Earth, not Theia.

Explanation:
many cellular functions can be compared with functions that occur in organisms. which is not a function that both cell and an organism share. A stores waste material for removal B provides structure and support C learn behaviors that aid in survival D conversion of nutrients into usable energy
Answer:
learn behaviors that aid in survival
Explanation:
learn behaviors that aid in survival is not a function that both a cell and organism share because a cell is a basic unit of life and contains some organelles that perform little functions while an organism comprises of many specialised cells that work to perform similar functions. An organism have central nervous system which comprises of brain and spinal cord. Organisms learn new behavior and acquire cognitive skills through the brain development. The brain and spinal cord receive electrical impulses sent from neurons and interpret it to meaningful information.
Learning behaviors that aid in survival is not a function that both cell and an organism share.
LEVEL OF ORGANIZATION:The cell is the basic and functional unit of living organisms. This means that the cell harbors the functional characteristics of living organism.
However, some functions are performed both at the cellular and organism level. Some of these functions include;

the type of energy which has the greatest impact on the state of matter is ..
A. sound
B. Gravitational
C. thermal
Answer: Thermal
Explanation:
When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough, that they change form. This energy is usually heat or thermal energy.

2. If allele B made bacteria resistant to antibiotics, which of the following is
correct:
a. The bacteria population is more likely to be killed by antibiotics
b. The bacteria population is less likely to be killed by antibiotics
C. The bacteria population will always be killed by antibiotics
Answer:
B. Less likely to be killed
Explanation:
If it is resistant it is much harder to kill because it resits the medication/ disinfectant
If allele B made bacteria resistant to antibiotics, then B. The bacteria population is less likely to be killed by antibiotics.
Antibiotics simply mean a medication that is used in destroying the growth of bacterias or slowing down their growth.
In this case, since allele B made bacteria is resistant to antibiotics, this means that it'll be hard for such bacterias to be killed by antibiotics.
Also, when a bacteria is resistant to a particular drug, the drug won't work on the bacteria.

The illustration below represents the movement of materials involved in a process that is vital for the energy-production and energy-transfer needs of an organism.
Oxygen
Water
Mamm
Glucose Carbon dioxide
In which organelle does this process take place?
Answer:
mitochondrion
Explanation:
The correct answer would be the mitochondrion.
The process of energy production in living organisms happens through oxidative phosphorylation during respiration. The process takes place in the mitochondrion. During respiration, glucose reacts with oxygen to produce carbon dioxide and water while ATP is generated in the process. The ATP represents the energy currency of the cell.
The entire process of respiration can be summarized by the following equation:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

Which of the following is an example of a physical variable of water quality *
Answer: Physical properties of water quality include temperature and turbidity. While chemical characteristics involve parameters such as pH and dissolved oxygen. These parameters are relevant not only to surface water studies of the ocean, lakes and rivers, but to groundwater and industrial processes as well.
I hope this is the answer if not I apologize :P
Answer:
One of the physical variables that affect the properties of water is temperature
Explanation:
I assume that by physical properties you mean external factors that affect the properties of the water correct? well depending on the temperature of the air that the water is exposed to the war can shift from either a liquid to a solid if it if the air is cold or it can change from a liquid to a gas when the air is hot. I'll explain how this works when the temperature of the air is hot the water will under go an exo thermic reaction (A reaction that causes things to emit heat and become hot) and because water boils at a certain point as the water gets hotter and hotter it will evaporate into mist. If the air around the water is cold then it produces an endothermic reaction which will cause the ice to get colder and colder as time goes on until it transitions from being a liquid to a solid in the form of ice. Hope this helps:)

Two people are exercising at a gym. Person X notices a burning sensation in several muscles, while person Y does not feel any discomfort at all.
Why are these two people feeling different sensations?
Answer:
See the answer below
Explanation:
Person X is feeling a burning sensation in several muscles because of the accumulation of lactic acid due to inadequate oxygen in their system. When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.
[tex]C_6H_1_2O_6 --> 2C_3H_6O_3[/tex]
Person Y does not feel any burning sensation in their muscles because oxygen is adequate in their system and they do not need to respire anaerobically. Person X exercise regime must have been more rigorous than that of person Y.

Answer:
The correct answer is - because 3×3×3 has the highest Surface area to volume ratio, diffusion in and out of the cell would be faster.
Explanation:
It is known that if the size of a sphere or cell increases, the volume is a cube, and the surface area is squared therefore volume increases faster than the surface area. If the volume is more and the surface area is less than diffusion will be less effective. diffusion takes longer and is less effective.
The decrease in the surface-to-volume ratio leads to diffusion to get less efficient. The Surface-to-volume ratio of a sphere decreases as the sphere gets bigger.

If an organism had 20 chromosomes, how many chromosomes would the daughter cell have after mitosis? After meiosis?
Answer:
After mitosis, the daughter cell has 20 chromosomes and after meiosis, the daughter cell has 10 chromosomes.
So the answer is 20 and 10
Answer:
[tex]\boxed {\boxed {\sf Mitosis: 20 \ chromosomes}}[/tex]
[tex]\boxed {\boxed {\sf Meiosis: 10 \ chromosomes}}[/tex]
Explanation:
Mitosis and meiosis are both types of cell divisions, but they are different.
Mitosis
1 cell division that results in 2 daughter cells used for growth, repair, and developmentThe cells are genetically identical with the same number of chromosomes as the parent cell.Meiosis
2 cell divisions resulting in 4 daughter cells for sexual reproduction The cells are genetically different and have half the number of chromosomes as the parent.The organism has 20 chromosomes.
Mitosis: same number of chromosomes=20 Meiosis: half the chromosomes= 20/2= 10After mitosis, the daughter cell has 20 chromosomes. After meiosis, the cell has 10.
