Explanation:

If a person who looks well could still be a source of infecting  microorganisms because the microorganisms present in its body not affected him due to powerful immune system but it can cause infection in the body of those person who have weak immune system. The other reason is that microorganisms are present in dormant state due to unavailability of good growing condition but when they got good conditions they became active and causes infection.

in 6-8 sentences, explain how stream volume and speed affect the size, shape and flow of streams and rivers.
sukhopar [10]

Explanation:

The higher the volume of water in a stream, the higher its speed and the wide its size and shape which ensures a proportionate flow rate.

To quantify how the speed of stream, we use the quantity, discharge in hydrology;

 Discharge is the volumetric rate of water flow past a point at a particular time.

  Discharge = \frac{volume of water}{time}

  • We see that discharge is directly proportional to the volume of water in a stream.
  • It is inversely proportional to the time taken.
  • We know that volume is the amount of space occupied by a body. It is function of its size and shape.
  • A big water body that is deeper, wider and longer will have more wate and a greater discharge.

After a signal binds to a signal receptor, the next step is transduction. Why is the signal transduction step necessary ls7c wee
mars1129 [50]

Answer:

Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.

Explanation:

Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
