hydrogen and oxygen to electricity.
A) compact fluorescent
B) energy efficient
C) hybrid vehicle
D) consumer
E) fuel cell
F) mandated
Answer:
Explanation:
Answer
A fuel cell works on the principal of converting hydrogen and oxygen to electricity. It works on the principle of breaking down the hydrogen into a proton and an electron. When electrons have passed through a passage (having created electricity) they are united with elements in the atmosphere producing heat and electricity and water.
What is the amount of heat energy needed to raise the temperature of
200 g of water from 10°C to 40°C? (water = 4.18 J/g°C)
Answer:
25116 J
Explanation:
Q = m × c × ΔT
c = 4.186 J/g°C
M=200 g
So,
Q = 200 × 4.186 × (40-10)
=200 × 4.186 × 30
=25116 J
state the difference between the synthesis and the breakdown of a protein. thanks!
Synthesis of protein is the building up of protein molecule while the breakdown of protein is the degradation of the protein molecule.
What is protein?Protein is one of the biological molecules that present in living organisms and contain it's building blocks known as amino acids.
The synthesis of protein is the process used by living organism to produce proteins from amino acids (that is the building block).
The breakdown of protein is the degradation of protein molecule which is also called catabolism.
Therefore, the difference between protein synthesis and breakdown is that synthesis of protein is the building up of protein molecule while the breakdown of protein is the degradation of the protein molecule.

A genius IQ is considered anything over 144. Let's pretend that
this is a genetic condition and that it is recessive. Genius IQ
is found in approximately 1 in 625 people worldwide (this is a
true statistic). Calculate the following:
1. The frequency of the recessive allele (genius IQ).
2. The frequency of the dominant allele (normal).
3. The percentage of heterozygous individuals (carriers).
According to the question, The percentage of heterozygous individuals (carriers). Thus, option "C" is correct.
What is the Hardy-Weinberg equilibrium theory?The Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
p is the frequency of the dominant allele,
q is the frequency of the recessive allele.
The genotypic frequencies after one generation are
p² (H0m0zyg0us dominant genotypic frequency),
2pq (Heter0zyg0us genotypic frequency),
q² (H0m0zyg0us recessive genotypic frequency)
Thus, option "C" is correct.

Molecules can have each of these forms of energy except light energy. The correct option is A.
What are molecules?A molecule is the smallest unit of a substance that keeps its content and properties. It is made up of two or more atoms that are joined together by chemical bonds.
Chemistry is built on molecules. The element symbol and a subscript indicating the number of atoms are used to identify molecules.
Single, neutral particles make up an atom. As neutral objects consisting of two or more atoms joined together, molecules are. A positively or negatively charged particle is called an ion.
There are three different kinds of molecules: atom-sized molecules, element-sized molecules, and compound-sized molecules.
Except for light energy, molecules can possess all of these types of energy.

If you placed blood tissue in a hierarchy pyramid, what hierarchical levels would go directly above and
below it?
O
Above: cardiovascular system
Below: heart
Above: heart
Below: organ system
Above: heart
Below: red blood cells
Above: cardiovascular system
Below: red blood cells
If you were to place blood tissue in a hierarchical pyramid, the hierarchical levels would be directly Above: cardiovascular system, Below: heart
What is the cardiovascular system?The cardiovascular system is made up of the heart and blood vessels. The heart works like a pump, allowing blood to be pumped. Arteries are blood vessels that carry blood from the heart to the body. Veins are blood vessels that ensure the return of blood to the heart.
With this information, we can conclude that if you were to place blood tissue in a hierarchical pyramid, the hierarchical levels would be directly Above: cardiovascular system, Below: heart

If a people consume more protein than their body needs, the excess protein is __________. excreted in their urine deaminated and used/stored as glucose or fat stored in their muscles excreted in their feces
When you consume more protein than your body needs, the excess protein is used to provide your body with energy or turned into fat.
How is protein essential for the body?The protein need for the body depends on the age, physical activities, development and changes. For all these processes, body need a large amount of protein. Our body is at the phase of breaking and building muscles, so high amount of protein is not harmful. Excess amount of protein is stored in the body in form of fats and break down when need for body energy requirements. So if the amount is increase it will result in weight gain and body size.
Even a high amount of proteins is healthy and safe, but massive increase in amount can cause harm to the body.
Thus,harmful effects of massive amount of protein depend on patient health.
