Compare the three types of RNA. Note significant similarities and differences. Use the table below to record your observations. basically just finish this table lol...
Answer: (Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure
(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it
Explanation: Plato, you're welcome
(Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure.
(Function) mRNA: carries the information in the DNA to the ribosomes, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain, tRNA: acts as an adaptor molecule.
What is mRNA, rRNA and tRNA?mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.
Moreover, the three major types of RNA are: mRNA (messenger RNA) : it provides the template for protein synthesis during translation, tRNA (transfer RNA) : it brings amino acids and reads the genetic code during translation, rRNA (ribosomal RNA) : it plays a structural and catalytic role during translation.
Therefore, the main difference between mRNA and tRNA is that mRNA serves as the messenger between genes and proteins whereas tRNA carries the specified amino acid into the ribosome in order to process the protein synthesis.

Explain why meiosis is such a critical process in the inheritance traits. Be as specific as you can.
Answer:
It ensures that sexually reproduced offspring have the correct amount of chromosomes when born, this ensures that disorders such as down syndrome don't occur. It also makes genetic variation possible, by way of genetic recombination, this is so that siblings don't look exactly the same, disregarding twins.
Explanation:
Meiosis is such a critical process in the inheritance of traits, and meiosis is important because it ensures that each daughter cell receives the correct number of chromosomes from the parent cells.
What is the significance of the inheritance of traits?Inheritance of traits allows for the transfer of beneficial traits from one generation to the next, allowing populations to adapt to changing environmental conditions, and the study of inheritance of traits can provide insight into the underlying genetic causes of diseases. The understanding of the traits helps in the improvement of agriculture and in other fields of biology.
Hence, meiosis is such a critical process in the inheritance of traits, and meiosis is important because it ensures that each daughter cell receives the correct number of chromosomes from the parent cells.

The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there is no rain? What would be the long-term effects on the plant if the drought were to continue? Explain your answer.
Answer:
I guess it would not grow??
Explanation:
Answer:
When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.

Cells genetically unique is it mitosis or meisis
Answer:
Meiosis
Explanation:
While mitosis makes two identical cells with the same numbers of chromosomes, meiosis makes four unique daughter cells, from which every cell has half of the number of the chromosomes as the parent cell.
Meiosis is the specified form of cell division, making the reproductive cells, like sperm and egg cells, for example.
The equation for photosynthesis can be written as 6CO2 + 6H2O --->
C6H1206 +602. How many oxygen atoms are present in the products of
photosynthesis?
Answer:
six
Explanation:
There are 6 oxygen atoms present in the products of photosynthesis.
What is photosynthesis?Photosynthesis is a process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose (a sugar) and oxygen, using energy from light. This process takes place in chloroplasts within the cells of plants and is essential for life on Earth, as it produces the oxygen that other organisms breathe and the food that supports the food chain.
The glucose produced by photosynthesis is used by the plant as a source of energy or stored for later use. Additionally, the glucose can be converted into other sugars, starches, and cellulose, which are used to build plant tissues.

Compare the thickness of the right and left ventricles. Which ventricle is thicker the right or left. Explain the difference.
Answer:
When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.
Explanation:
In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.
To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.
The right ventricle is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs. The left ventricle has a thicker muscular wall because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater.The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.

How can fracking impact water quality? (1 point)
A.Methane leaks make the water supply flammable.
B.Power pumps drain water from rivers and reservoirs.
C.The heated water becomes unfit for consumption.
D.Smelting releases toxic metals into the water supply.
Answer:
a
Explanation:
Due to the current relationship with groundwater and surface water, fracturing fluids like return fluids might pose a risk to both, hence option a is correct.
What is fracking?It's possible for water to get contaminated during fracking owing to chemicals that are accidentally spilled,in the water during the migration of thermogenic methane gas.
Since a hydraulic fracture might intercept a natural fracture, such as a geological fault, and be connected to the surface, this presents another potential source of pollution.
Therefore, presence in the subsoil may be encouraged during the fracturing process, which may enhance the incidence of chemical reactions and the production of new contaminating substances, hence option a is correct.

This plant is Macaranga hypoleuca. Compare its leaves to those of the plants around it. What is the relationship between the leaves of this plant, photosynthesis, and competition with neighboring plants?
Answer:
Explanation:
This plant's leaves, compared to the plants around it are far larger. Their big leaves are good for photosynthesis because they are broad and flat, giving plenty of surface area for light to be absorbed. They are also thin, which means diffusion of gases such as carbon dioxide can happen quickly. As far as competition, the bigger leaves give them an advantage because they are able to absorb more light in less time than their smaller-leaf neighbors.
Macaranga hypoleuca has adverse effect on the neighboring plants because this is a tree growing up to 30 meters tall and has a dense canopy. This tree grow higher as compared to neighboring plants so harvest more sunlight and do more photosynthesis.
While on the other hand, the neighboring plants can't get sunlight due to this plant so less photosynthesis occur and experience a stunted growth so we can say that this tree has negative effect on the neighboring plants.
