What processes are made possible by the cell membrane?

Answers

Answer 1
Endocytosis. Endocytosis is the process in which cells absorb molecules by engulfing them. The plasma membrane creates a small deformation inward, called an invagination, in which the substance to be transported is captured. Diffusion is the movement of particles from high concentration to low concentration in a substance. This process is essential for life on Earth, allowing for the movement of molecular compounds into and out of the cell.

Endocytosis. The endocytosis process occurs when the cell introduces molecules or particles.

Phagocytosis. If endocytosis captures particles, then the process is known as phagocytosis.

Pinocytosis. In the event that these captured particles are liquid, the process is known as pinocytosis. exocytosis.

Finally, when the vesicles reach the cytoplasm and fuse with the cell membrane, releasing their contents, this process is called exocytosis.
Answer 2

Diffusion, pinocytosis, carrier-mediated transport, and transcellular transport are the mechanisms that control the movement of molecules across membranes.

What is diffusion ?

Diffusion is the overall net movement of anything from a higher concentration to a lower concentration. A gradient in the Gibbs free energy or chemical potential drives diffusion.

The process by which cells take in molecules by engulfing them is known as endocytosis. The substance to be carried is caught in a little invagination that the plasma membrane forms that extends inward.

The terms "concentration gradient," "pressure gradient," and "temperature gradient" are used to describe changes in concentration, pressure, and temperature over a given distance. The Latin term diffundere, which meaning "to spread out," is the root of the English word diffusion.

Thus, Diffusion, pinocytosis, carrier-mediated transport, and transcellular transport are the mechanisms that control the movement of molecules across membranes.

A significant shift in the environmental conditions over a very short period of time caused most groups of dinosaurs to become extinct because of their inability to adapt fast enough. This allowed for a variety of niches to open providing current organisms new opportunities. Mammals were one group of organisms that took advantage of this environmental change, filling niches that were unoccupied and eventually developing new species that were specifically adapted to their particular environment.

Then it was time to transplant the plant into the family yard so it could continue growing. When the soil in the container was weighed, its mass was 50 kg. Over the years Jasmine's parents neither added nor removed soil from the container with the plant in it. How did the plant increase in mass by 74 kg while the soil did not change in mass and never needed adding to over the years?

Answers

Answer:

Following are the solution to the given points:

Explanation:

In point a:

When a light absorption dye was to be introduced to optimize the plant's absorbing capacity, the paint could absorb wide different wavelengths besides the observable light spectrum. It must also absorb the UV only at IR light rate to maximize the fluorescence intensity.

In point b:

Its molecule in the production of pentose sugar is the nitrogen and hydrogen atoms of carbon dioxide and water ions of air. Its water oxygen atoms are emitted through oxygen atoms during this phase.

In point c:

Its plant increased with weight while decreasing the weight of the earth, so because manufactured goods needed for plant growth are carbon dioxide from water and air, provided to a plant every day and nitrogen extracted from of the atmosphere through means of microbial materials into nitrogen. So, even if the plant raised its weight, the soil does not change the weight.

A scientist wanted to formulate a pill to attack a specific type of bacteria that infects the throat. Which biological component would be best to use as a model for the pill’s function?
bacteriocytes
phagocytes
complement system
antibodies

Answers

Answer:

thx but the answer is D

Explanation:

A pill formulated to attack a specific type of bacteria that infects the throat would best follow the operations of antibodies.

What are antibodies?

Antibodies are chemicals produced by the immune system of the body in response to external attacks by foreign substances.

In other words, antibodies are like weapons deployed to defend the body from external attacks.

A pill designed to attack a specific type of bacteria that infects the throat will be most effective if it follows the operations of antibodies.

Since different antibodies are produced for different external invasions, the pill will also be most effective by being specific in its actions.

Multiple sequence alignment is a method that can be used to compare three or more biological sequences to determine homology and evolutionary relationships between species. This is done by selecting a target protein or DNA sequence (consensus) and comparing it across other species’ sequences. Conservation is a statistical analysis that describes how much the target sequence is observed across the selected group of species. A higher conservation score indicates that the protein or gene is more ancient or more critical across species.

What information can be gained about the structure and function of plants by ring barking?​

Answers

Answer:

About its different layers and their functions in the plant body.

Explanation:

By studying the structure and function of the plants by ring barking, we find out that the ring barking is very important for the plant because it provides support as well as protection to the inner part of the stem against environmental conditions such as temperature and intense light etc. These barks are responsible for the storage of water which can be used during drought conditions. This ring barking provides information about different layers of stems such as  periderm, cortical and phloem tissue that has a specific function in the plant body.

How are photosynthesis and cellular respiration connected as a cycle?

Answers

Answer:

Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off).

glucose  +  oxygen  + (energy)  →  carbon dioxide  +  water

C 6 H 12 O 6  +  6 O 2  →  6 CO 2  +  6 H 2 O

Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (thus making it exothermic).

carbon dioxide   +  water  +  energy  →  glucose  +  oxygen  

6 CO 2  +  6 H 2 O  →  C 6 H 12 O 6  +  6 O 2

As you can see from the equations, they are essentially the reverse of each other.

Another difference is how they are used. Respiration occurs in the mitochondria of all living cells, whereas only plants photosynthesize.

In plants, they make their own glucose using the sun's energy, then respire to allow them to use the glucose for the energy they can use. The glucose can also be stored and used in many other ways other than in respiration.

Use two examples for plants to explain how the development of new technologies such as radioisotopes has increased our knowlegde of reactions in plants.​

Answers

Answer: The radioactive isotopes can be used to track many physiological functions and chemical reactions occurring within the cells of the living organisms including plants.

Explanation:

Phosphorus uptake by the plants: Phosphorus is an essential mineral required by the plants for their growth and metabolism. The radioactive phosphorus-32 can be used to track back the rate at which the plant absorbs the phosphorus from the soil. This can help scientists to identify plants that can absorb phosphorus more quickly.

Pesticides levels in the plants: The pesticides levels in the plants can be traced by using radioisotopes such as chlorine-36. This can be used to trace the fact that how much of pesticide is present in the soil and how much of it is utilized by the plants. This is helpful identifying the fact that which pesticide is useful for the growth of the plants.
