During diffusion, molecules move

Answers

Answer 1
Answer:

Answer:

The correct answer will be- the molecules move from high concentration  to low concentration.

Explanation:

Diffusion represents the movement of solute particles that is ions or molecules. The movement is driven by the concentration gradient that is from the higher concentration to lower concentration.

The diffusion can be categorized into two types: simple and facilitated diffusion.  In biology, diffusion plays an important role as the important solute particles move into and out of the cell through this process.

Thus, the molecules move from high concentration to low concentration is the correct answer.

Answer 2
Answer:

Final answer:

During diffusion, molecules move from area of high concentration to an area of low concentration to achieve equilibrium.

Explanation:

During diffusion, molecules move from an area of high concentration to an area of low concentration. This happens due to the random motion of the molecules. The goal of diffusion is to achieve equilibrium, where the concentration is equal throughout the space.

Proteins have a variety of functions within a living cell. Describe at least three of the possible functions of proteins, and explain how proteins can be so diverse when there are only a limited number of different amino acids.

Answers

anonymous  3 years agoProteins are involved in almost all of the cell's functions. They can act as: Transportation: they can transport hydrophobic molecules in blood for example Regulation: protein hormones and enzymes Receptor: can act as receptors on cell surface and in the subsequent signal transduction (G-protein for instance) It is true that all proteins are made up of up to 20 amino acids, but there are several reasons for their diverse actions: -One reason is the possible sequence and number of amino acids: Met-Ser-His is different from Met-His-Ser for example. Besides, you have different chain length, for a protein is made up of long chain of polypeptide (longer than 50-70 amino acids) and can have any of the 20 amino acids with repetition, so using simple probability, this can provide up to practically unlimited combination with proteins that have chains of thousands of amino acids. -Another very crucial reason for the diversity of protein action is the conformation. A protein passes by at least 3 conformational stages before becoming mature. The straight amino acid chain is the primary structure of the protein that can never be active. Spatial modification of this primary structure results in a secondary structure, Helix or Beta-pleated sheets (or other coiling structure), that is also inactive. Further coiling and bending of the secondary structure produce a 3-dimentional conformation that is the active form of the protein. Moreover, many proteins can undergo further conformational rearrangement and combination with other protein sub-units producing a quaternary structure.

Insects are most likely found in which aquatic zone?a.
pelagic
b.
littoral
c.
benthic
d.
all of the above

Answers

Answer: b. littoral

Insects are most likely found in the littoral aquatic zone. Littoral zone are rich in oxygen and has abundant and diverse food resources. Therefore, this zone supports high diversity of insects. Large taxa of insects like aquatic beetles and bugs, caddisflies, dragonflies and damsflies are important littoral zone communities.

Henry eats rice for lunch, which contains starch. Which enzyme catalyzes the reaction that takes place and which product is the result of this reaction? Amylase catalyzes the reaction; glucose is the product Pepsin catalyzes the reaction; lactase is the product Lactate dehydrogenase catalyzes the reaction; lactate is the product

Answers

amylase catalyzes the reaction; glucose is the product

Answer:

Amylase catalyzes the reaction; glucose is the product

Explanation:

In the process of digestion, polysaccharides like starch are broken down into monosaccharides before being absorbed. Digestion of starch is catalysed by amylase enzymes which are salivary amylase and pancreatic amylase. Salivary amylase begins digestion of starch inside mouth during chewing process. The digestion is further carried out by pancreatic amylase in small intestine. The starch is hydrolysed in digestion process and the products are glucose, maltose, maltotriose and α-dextrins. Disaccharides like maltose are further converted into monosaccharides by enzymes like maltase which are present in brush border of small intestinal cells.

3a. Scientists think some organisms have eyespots on their bodies to help them lure in prey. Choices True False

Answers

Answer:

False

Explanation:

The eye spot instead creates a disguise and used to misdirect predators. The eyespots are a defense mechanism for the organism. Scientists have tested this by painting eye spots on a gake prey and a fish was used a s the predator. The predator was discovered to have attacked the fake eyespots more often as it thought it was the prey's head.

Eyespots on a prey can also make the predator to think that it is facing a larger animal. An example is the butterfly which have large false eyes on its wings.
