Answer:

a) when cells are small the movement of food and waste can be efficiently handled by the cell membrane

Explanation:

Cells need to get their nutrients and waste in and out of their cell membrane every quickly. Cells are hard workers anyway! The other options also don't make much sense. The cell shape doesn't mean much to their function, and size doesn't impact shape. The cell's internal parts (mitochondria, vacuole, etc) don't support the cell membrane, they have their own functions to focus on. Cells don't work together in tissue but they can interact with each other when needed.

Answer:

The statement (a) correctly describes that why cells are so small.

Explanation:

Cells are formed of cytoplasm enveloped by a phospholipid bilayer. In the cells of plants, a supplementary cell wall also prevails. The cytoplasm accommodates various metabolic activities that need a spontaneous supply of nutrients. During the same time, metabolic wastes originate from these reactions, which are required to be eradicated. All this uptake and discard of nutrients and waste components occurs by mediation across the cell membrane via passive, active, or facilitated transport.  

In the absence of any circulatory system, these cells depend entirely on the process of diffusion through the membrane. The brisk interchange of molecules can only take place if diffusion occurs over brief distances. Thus, this rate of uptake of nutrients within the cells and discarding of wastes into the external surroundings hugely relies upon the cell surface, which is restricted by the cell membrane. Thus, surface area of the cell is one of the limiting factors to monitor the rates of diffusion of these molecules. Therefore, when the cells are small, their wastes and food can be handled effectively by the cell membrane.

Chemicals called ________ are stored in neurons and released when the cell is stimulated by a signal.
Papessa [141]

Answer:

Neurotransmitters

Explanation:

Neurotransmitters are the chemicals present in the body used for the propagation of action potential. These neurotransmitters are also known as the body chemical messengers.

Neurotransmitters are stored in the neural cells. These chemicals are generally released when the cell is stimulated by the specific signal. The effect of neurotransmitter may be excitatory or inhibitory.

Thus, the answer is option (4).

Klio2033 [76]

Answer:

The answer to your question is ACUCTTCUGGUCCCAACA

Explanation:

Base sequence

                         TGAGAAGACCAGGGTTGT

Nitrogenous bases change from DNA to RNA

                   DNA                      RNA

                      Adenine                 Uracil

                      Thymine                  Adenine

                      Guanine                 Cytosine

                      Cytosine                 Guanine

Then from left to right, the new sequence the RNA is
