A potato core was placed in a beaker of water as shown in the figure below. Which diagram best represents osmosis? (NOTICE: Starch is TOO LARGE to move through a membrane on its own
Answers
Answer:
The correct answer is - option A.
Explanation:
Osmosis is the movement of the solvent in a solution into the higher concentration are of solute through the semipermeable membrane such as cell membranes.
The movement of the solvent (water) through a semipermeable membrane is always from a high water conentration to a low water concentration. Solute molecules do not move through a semipermeable membrane during the osmosis process

What is the function of a seed's endosperm?
a) it divides to become the plant's first root
b) it will become the plant's seed leaves
c) it protects the plant embryo
d) it provides nourishment for the growing plant
Answers
Answer:
It's D
Explanation:
I had it on my quiz
Endosperm regulates seed development and facilitates the transmission of maternal nutrients to the embryo. Therefore, option (D) is correct.
What is endosperm?The endosperm is a type of tissue that develops during fertilization and is found inside the seeds of most angiosperm plants. It gives the embryo the nutrients it needs to grow.
Endosperm is produced when the two sperm nuclei that are contained within a pollen grain make their way into the interior of a female gametophyte.
The endosperm contains carbs, protein, and minor amounts of B vitamins and minerals. These components affect our bodies differently: Bran and fiber inhibit starch digestion, preventing blood sugar increases.

What is the question?
Explanation:
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?
Answers
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.

photosynthesis?
Answers
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.

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.
Answers
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.

(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

(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.
