Which structure is not made up of RNA?a. mRNA
b. tRNA
c. ribosome
d. amino acids

Answers

Answer 1

Answer:
d. amino acids

The two factors that determine the shape of a protein
1. Primary structure. The sequence of amino acids. Amino acids are the building blocks of protein. It is a strong of linearity that can be thousands in length. Moreover, the formation of the amino acid and its system is influenced by its genes’ nucleotides arrangement.
2. Hence the next factor is how is the structure of the amino acids bended and folded with itself that forms the certain protein molecule and forms the larger complex structure

Answer 2

Answer: The answer is d. amino acids :)

Doug plants a few peas. After two days, he sees the shoot and the root forming. He observes that the shoot grows upward, toward the light. The root grows downward, into the soil. Why do these embryonic organs grow in a specific direction?A. The shoot is positively phototropic and positively gravitropic; the root is positively phototropic and positively gravitropic.

B. The shoot is positively phototropic and negatively gravitropic; the root is positively gravitropic and negatively phototropic.

C. The shoot is positively gravitropic and negatively phototropic; the root is positively phototropic and negatively gravitropic.

Answers

The answer is B. The shoot is positively phototropic and negatively gravitropic; the root is positively gravitropic and negatively phototropic.

Phototropism is reaction of a plant to a light stimulus. Growth of the plant or its part grow towards the light stimulus is called positive phototropism. Growth of the plant or its part away from the light stimulus is called negative phototropism.
Gravitropism is reaction of a plant to gravity. Growth of the plant or its part in the same direction as gravity is called positive gravitropism. Growth of the plant or its part grow in the opposite direction of gravity is called negative gravitropism.

The shoot is positively phototropic (grows toward the light) and negatively gravitropic (grows upward, in opposite direction of gravity).
The root is negatively phototropic (grows into the soil, away from the light) and positively gravitropic (grows downward, in the same direction as gravity).

B for plato

Explanation:

During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur, which of the following statements must be true?A.) The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.

B.) New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.

C.) New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.

D.) The new compounds that are formed must be more complex than the food molecules that were broken down.

Answers

During cellular respiration, the bonds of food molecules are broken to energy can be released to fuel other cellular processes. In order for this to occur, new compounds with lower-energy bonds must be formed when high-energy bonds in food molecules are broken.
This is due to the Law of Conservation of Energy.

Answer:

The correct answer is statement B.

Explanation:

The cellular procedures of respiration and photosynthesis involve the transformation of energy and matter. On the basis of the law of conservation of energy, energy can neither be formed nor destroyed. Thus, to attain excess energy in order to provide energy for the cellular procedures, the bonds produced in the new compounds must possess less energy in comparison to the bonds in the original food molecules.

Potatoes were the main crop in Ireland in the 1800s. Almost the entire population of Ireland was dependenton a single variety of potato, the “lumper.” These potatoes were reproduced by a method of asexual
reproduction known as vegetative propagation. In the middle of the 1800s, a disease caused by a fungus
killed almost the entire lumper crop within two years. As a result, millions of people in Ireland died of starvation.
The most likely reason the potato disease was able to destroy the potato crop in such a short time is that the
(1) potato population lacked variations
(2) lumper variety had a long reproductive cycle
(3) lumper had several variations caused by vegetative propagation
(4) potato population in Ireland utilized all of the finite resources

Answers

1 is correct. Since the potatoe population lacked variations, it was more susceptible to diseases.

Final answer:

The potato crop was likely destroyed quickly due to a lack of genetic diversity in the lumper potato population. All potatoes were virtually identical, thus none had resistance to the disease, leading to the rapid spread and devastation.

Explanation:

The reason the potato disease was able to destroy the potato crop in such a short time is likely option 1: the potato population lacked variations. In biology, this situation describes a lack of genetic diversity, meaning all individuals in the potato population were genetically identical or nearly so. Consequently, when the fungus that caused the potato blight appeared, it affected all lumpers in the same manner. If there had been more genetic diversity in the potato population, some individuals might have had natural resistance to the fungus and could have survived, allowing the population to recover more quickly.

Energy frequently changes form as it moves through biogeochemical cycles. Energy transfers in lightning fixation differ from those in photosynthesis because in lightning fixationradiant energy transforms into chemical energy; in photosynthesis, electrical energy transforms into chemical energy.

electrical energy transforms into chemical energy; in photosynthesis, chemical energy transforms into electromagnetic energy.

electrical energy transforms into chemical energy; in photosynthesis, radiant energy transforms into chemical energy.

radiant energy transforms into chemical energy; in photosynthesis, chemical energy transforms into radiant energy.

Answers

Energy transfers in lightning fixation differ from those in photosynthesis because in lightning fixation electrical energy transforms into chemical energy; in photosynthesis, radiant energy transforms into chemical energy. Thus, the correct option is C.

What is Photosynthesis?

Photosynthesis may be defined as the process through which green plants and some photosynthetic algae synthesize their own food (glucose) with the help of carbon dioxide and water in the presence of sunlight.

During lightening, the form of electrical energy is transferred into heat or thermal energy with an intermediate of chemical energy, while during photosynthesis, plants capture sunlight in which radiant energy of sunlight gets transferred into chemical energy.

Therefore, the correct option for this question is C.

Explanation:

i took the test and got this question right

I'm not sure what the question is, but the only traits that are passed down are the ones that can be found in the germ (sex) cells. Radiation exposure alters somatic (body) cells usually, but can also alter germ cells, so it depends.
