If a bacterium cell can move around in its environment, it probably has which type of structure?

Which of the following is true of cells in batch culture? Cells never reach exponential growth rates. Metabolic wastes do not ac

Nataly [62]

Answer:

Option (3).

Explanation:

Batch culture may be defined as a type of culture which are refereed as stack and operated as influx of the reactant up to the maximum level. This technique is generally used to grow the micro organisms.

The cell mass do not decrease or increases as the cell divides in the batch culture. The new batch are added during the culturing process. The cell mass remains constant in batch culture.

Thus, the correct answer is option (3).

Answer:

Paget's disease

Explanation:

It is a chronic condition of bones understood as a disorder of the normal bone remodeling and recycling processes.

Paget's disease results in irregular thickening of bone tissue due to new bone tissue gradually replaces old bone tissue.

Paget's disease commonly affects pelvis, skull spine and legs, causing pain and deformity in them.

It also produces broken bones, hearing loss pinched nerves in the spine due to this disease increases with age.

_____ that are not reabsorbed drift out of the synaptic gap, through diffusion. This is how the synaptic gap is cleared, in prep

BigorU [14]

Answer;

-Nuerotransmitters

Neurotransmitters that are not reabsorbed drift out of the synaptic gap, through diffusion. This is how the synaptic gap is cleared, in preparation for the next release of a new batch of these chemical messengers.

Explanation;

-The majority of neurotransmitters drift across the synaptic gap and come into contact with receptor sites of the receiving neurons dendrites. Receptor site is the location where neurotransmitters attach on the receiving side of the synaptic gap. Because there are a variety of neurotransmitters a variety of receptor sites also exist.

-It is necessary for the right neurotransmitter to fit a corresponding receptor site to convey the message.

-When the neuro transmitters latch onto the receptors of the dendrites of the receiving neuron tiny gates in the receiving cells membrane fly open ushering positively charged particles into the cell and restarting the cycle of action potential.

-The firing of one neuron contributes to the potential for neighboring neurons to fire as a result of its chemical message. Reuptake process by which neurotransmitters are reabsorbed by the sending terminal bud. Neurotransmitters that are not reabsorb drift out of the synaptic gap through diffusion
