<span>For photosynthesis to occur, the necessary parts are sunlight, water and carbon dioxide or CO2. The role of ATP in the reaction is that it is itself generated by the first stage of photosynthesis, and is therefore a product of the reaction. It provides energy for the next stage.</span>

The probability of a ___________ channel being open is controlled by the membrane potential.
Anna11 [10]

Answer:

(b) Voltage gated

Explanation:

The cell membrane acts as a barrier that separates two aqueous media of different composition, the extracellular and the intracellular, regulating its composition. Most of the liposoluble drugs and solutes, when not ionized, directly cross the cell membrane through a passive diffusion process, which facilitates the passage of the medium where it is more concentrated to the one that is more diluted. The difference in concentration between the two media is called the concentration gradient, and diffusion will continue until this gradient is eliminated. According to Fick's law, the speed of this process will be much faster the higher the concentration gradient and the liposolubility of the molecule and the smaller its size.

More hydrophilic molecules, such as ions, are immiscible in membrane lipids and pass through specific specific transport mechanisms. In some cases, ions pass through hydrophilic pores called ion channels, and in others a favor of their concentration gradient is transported by binding to the transporter or transporter proteins. Both transport systems are passive and therefore do not consume energy. The great advantage is that the ion channels allow the flow of ions through a much higher speed than that of any other biological system. The flow of ions through each channel can be measured as an electric current, which is capable of producing rapid changes in membrane potential.

hram777 [196]

Answer;

-A teenager teaches her brother how to text (same generation).

Explanation;

-Cultural trait is a characteristic of human action that's acquired by people socially and transmitted via various modes of communication.Culture is the integrated pattern of human knowledge, belief and behavior. Every society has its own particular culture.

-Vertical transmission occurs from parents to offspring and is a function which shows that the probability that parents of specific types give rise to an offspring of their own or of another type. Horizontal transmission is cultural transmission taking place among peers in a given population.

Which group of organic compounds stores genetic information?
vaieri [72.5K]
I got D, C, A, B, C, B, D, C. 

C (proteins) instead of D (nucleic acids) because if you look at a nucleic acid structure, you'll see that sulfur is not found in it. Sulfur is found in two amino acids (methionine and cysteine), which means it could be found in proteins since amino acids build proteins

Which of the following is a part of the cell theory?
Neporo4naja [7]

Answer:

The correct option is D. New cells are produced from existing cells is a part of the cell theory.

Explanation:

Cell theory can be described as one of the earliest theories of biology which states that cells are the basic unit of life out of which all living things are made. The modern cell theory comprises of three main parts:

  1. All the living forms of life are manufactured from cells.
  2. Cells are the main unit which are involved in properly organizing a living organism.
  3. New cells arise from pre-existing cells.
