Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.

Given the formula D=M/V, a substance with a Density of 50 gm/cc, with a Volume of 10 cc, has a Mass of
Answer:500
Explanation:density=mass/volume.
Just substitute 50 and 10 in your equations and you’ll get your answer (mass).
50=m/10
(10)50= m/10 (10)
500=mass
Answer:
500
Explanation:
M=D*V, so 50 times 10.

Explain the relationship between photoshnthesis and cellular respriation. Be sure to include the main purpose of both and where they occur inside the cell
Answer:
photosynthesis occurs in the chloroplast of plant cells. cellular respiration starts in the cytoplasm then reacts in the mitochondria. if you look at the chemical equation of both photosynthesis and cellular respiration they are reverse of each other. in cellular respiration sugar goes in with oxygen, what comes out is ATP(energy), water, and carbon dioxide gas. in photosynthesis energy, water, and CO2 goes in and what is made is sugar and oxygen. The main purpose of cellular respiration and photosynthesis is to make energy and to store energy for later use.
Explanation:
What is the evidence scientists have to support endosymbiosis and the evolution of prokaryotes to eukaryotes?
Answer: The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Compare and contrast characteristics and use his own diodes and triodes
Answer:
Comparison of characteristics and use of diodes and triodes is given below:
Diode and triodes both are electrical components but diode allows the flow of current in only one direction while triode has three electrodes.Diode consists of two terminal (anode and cathode) while Triodes have three terminals (cathode, anode, and grid). A diode is an electrical component used to control voltage while triode is a current controlled device. Diodes used in modern electronics such as LED while triodes are used in RF heating systems.Answer:
1. Conditions that result in the emission of electrons from a conductor:
Heating the conductor to a suitable temperature
Exposing the conductor to a strong light
Subjecting the conductor to a very high applied voltage
Subjecting the conductor to high-speed electrons from another source
2. Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.

Which student, if either, is most correct in their claim regarding the ATP/ADP cycle?
A. Brianna's claim is correct - the removal of a phosphate group (or the breaking of
a chemical bond) supplies a great deal of energy from the cell and the ATP/ADP process is not continuous.
B. Neither student is completely correct. Oscar is correct in that this process is a
cycle and Brianna is correct in that the removal of the phosphate group supplies the most energy
C. Oscar's claim is correct - the addition of a phosphate group (or the making of a
chemical bond) supplies a great deal of energy from the cell and the ATP/ADP
cycle is continuous.
D. Both students are correct - Oscar's claim is correct for the process of
photosynthesis and Brianna's claim is correct for the process of cellular
respiration.
Answer:
A
Explanation:
because it is the the ATP/ ADP does not process which is true.

ANSWER QUICKLY
The average size of a grocery store chicken has more than doubled in the past century. What is the most likey reason for this change?
A. Natural selection resulted in a larger species of chicken.
B. Artificial selection created a larger breed of chicken.
C. Mutations occur less frequently in chickens than they did a century ago.
D. Grocery stores used to sell younger chickens.
Answer:
B, artificial selection resulted in a larger species of chicken.
Explanation:
People breed the largest animals (in this case chickens) or plants to improve agriculture.
Hope this helps! ;)
The average size of grocery store chicken has more than doubled in the past century because artificial selection created a larger breed of chicken. The right option would be B.
Artificial selection refers to deliberate actions by humans to selectively breed organisms based on desired traits.
Because big size chickens are desirable for their meats, breeders and genetic engineers would select this trait and favors it over other alternate traits using appropriate scientific procedures (such as controlled mating). Thus, chicken with undesirable traits gradually fades off the population while those with desirable traits are made to thrive.

a student observed a food sample that’s left a greasy spot on paper and also gave a positive test for starch. which two organic compounds are present in the food sample ?
Answer:
The correct answer is - fats and carbohydrates are two organic compounds that are present in the sample.
Explanation:
The greasy spot present on paper shows that there are fats present in the food sample that can be butter, ghee, or oil. Fats are the organic compound that provides energy to the organism that eats fat, however, more than a limit fat is harmful to any person.
The starch test suggests that food samples have starch present in the sample, starch is nothing but a polymeric carbohydrate. Carbohydrate is a basic organic compound that provides energy to the body or different organism.
Thus, the correct answer is - fats and carbohydrates.
