Answer:
The correct answer is B. The virus can infect the host.
Explanation:
- As the host and the virus both remain in the agar plate, the virus is capable of infecting the host cells.
- The host cell multiplies and grows by utilising the nutrient from the agar medium.
- After the virus particles infect the host, they replicate inside the host and produce new progeny virions which get released out of the host cell by killing it.
- The newly formed virions infect other host cells and the process continues.
- The killing of the host cells by the viruses result in the generation of clear zones on the agar plate which is also known as the zone of exclusion.
- In the zone of exclusion region, the host cells have been killed by the viruses.
Answer:
Sister chromatids on the top and Chromosomes on bottom
Answer:
Because of different abiotic factors (Temp, humidity, ect.)
None of the above.
Erosion is more likely to increase when the amount of vegetation decreases. The potential for soil erosion increases if the soil has no or very little vegetative cover of plants.
Plants and their residue form a cover that protects the soil from direct raindrop impact and splash, tending to slow down movement of runoff water and allows excess surface water to infiltrate, preventing erosion by water.
Plants root systems tend also to anchor top soil in place such that it is firm and cannot be easily blown away by wind thus preventing erosion by wind.
The function of acetylcholinesterase in the synaptic left is to bind Ach receptors on the post-synaptic membrane and relays signal from the nerve. Acetylcholinesterase is an enzyme that catalyzes the breakdown of acetylcholine. Some other cholines functions as neurotransmitters. ACHE gene is found in the chemical synapses and neuromuscular junctions of cholinergic. Acetylcholinesterase belongs to carboxylesterase group of enzymes. During the time of neurotransmission Ach which is released from presynaptic neuron to synaptic cleft. Acetylcholinesterase is also found in red blood cells membranes whereby different forms constitute the Y blood group antigens.
