Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.

A. Equal
B. Higher
C. Lower
D. None of the above

Answers

Answer 1

Answer:

lower

Explanation:

Answer 2

Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.

What is diffusion?

Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.

If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.

This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.

Therefore the correct option is C.

What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?

Answers

Answer:

Please mark as brainliest!!!

Explanation:

Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.

It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.

How do active and passive transport help a cell respond to changes in the environment?

Answers

- both transport things across the cell membrane
- help the membrane maintain homeostasis

Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.

What is Cellular transport?

Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.

The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.

Which domain includes organisms that are called extremophiles (organisms which live in extreme environments)?

Answers

Answer: archaea

Explanation:

Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.

Archaea domain includes organisms that are called extremophiles (organisms which live in extreme environments).

What are the characteristics of archaea?

Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.

The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.

If there is an overgrowth of another organism called Archaea, then the symptom picture can be very different. There can still be bloating, abdominal pain and cramping, but Archaea usually cause constipation, not diarrhea.

What are the identifying features of carbohydrates

Answers

Carbohydrates are one of three macronutrients, besides protein and fat, that you need in fairly large quantities to maintain your life and important body functions. They are revered for their ability to energize you quickly but also blamed for thickening waistlines in the rise of so-called low-carb diets. Nutritionists and public health officials still encourage you to get most of your calories from this nutrient, so it's important to learn to identify high-quality, healthy carbohydrates.
