In scenarios 2 and 3, the simulation settings are such that it takes 30 days to run the vaccination campaign and 14 days to develop immunity. Explain the logic behind these setting choices. Hint: there are two reasons, one is biological and one is logistical.
The two possible reasons for these setting choices are that it takes to the body around 14 days to develop immunity and that vaccinating a lot of people is logistically demanding.
What are vaccines?Vaccines are biological substances that help the body develop immunity against a virus, bacteria, etc. This is possible because vaccines contained a weakened or modified version of the pathogen that would help the body secrete specific antibodies for the real pathogen.
What is the possible reason for the 14-day setting?Immunity does not occur immediately, indeed, it takes the body up to 14 days to build up immunity. This includes the modern vaccines.
What is the possible reason for the 30-day setting?On the other hand, giving vaccines to large populations is quite demanding and challenging. Due to this programs with multiple weeks including four-week programs are ideal.

A cell has 6 chromosomes during G1. During G2 it has
How many chromatids and
strands of DNA?
Answer:Neuronal cells in G2 phase demonstrate tetraploid (4N) DNA content or, more precisely, possess a nucleus with 46 replicated chromosomes.
Explanation:In the G1 phase, there are 12 chromosomes. In the S-phase of the cell cycle, the amount of DNA gets doubled. There is doubling of the chromatids but the chromosomes number remains same. The number of chromosomes in the G2 phase will be same as 12 chromosomes and the number of chromatids will be 24.

Neurons in the visual cortex respond to which type of stimulus?
Answer:
luminance
Neurons in the visual cortex respond essentially to the variations in luminance occurring within their receptive fields, where each neuron fires maximally by acting as a filter for stimulus features such as orientation, motion, direction and velocity, with an appropriate combination of these properties
Explanation:
Neurons in the visual cortex respond to luminance stimulus. They respond selectively to various stimuli depending on the features.
What do you mean by Neurons?Neurons may be defined as the cells which are responsible for receiving sensory input from the external world and processed in the brain.
Neurons in the primary visual cortex respond to local edges or contours at a particular orientation, motion, direction, and stereoscopic depth.
