Answer:
False, Chemical, Chemical, Physical, True
Explanation:
You had most of the brain cells you would ever have, but the wiring was immature on the day you are born.
- In a human body at prenatal age their are maximum number of brain cells or neurons.
- At the time of birth these neurons reduces but still the maximum in all age groups.
- But the wiring which connects these neurons or brain cell is few that means the connection between one neuron to another is poor that is why the brain control and coordination ability in synchronous with the muscles is poor.
- The wiring can be characterized by the synapse. It is a junction between one and another neuron where the information is transferred.
- At the time of birth the number of synapses per neuron is 2500 but in the age of 2-3 the number of synapses increases to 15000 per neuron that promotes neural and muscular coordination.
- Thus it can be said that newborn will have maximum number of neurons but the wiring or neural coordination via synapse will be immature.

False.
Most of the cell's organelles<span> are in the cytoplasm.</span>
1) In prokaryotes, which have cytoplasm, there are no organelles.
2) In eukaryotes, the nucleus (which is an organelle) is surrounded by the cytosplasm, but is not contained within the cytoplasm. The cytoplasm is the region of the cell outside the nucleus, out to the plasma membrane, so the nucleus is excluded from the cytoplasm
post-exposure prophylaxis. PEP for short. It involves taking medicine after contact with HIV.
Treatment must begin within 72 hours. PEP is only available from a healthcare provider, emergency room, urgent care clinic, or HIV clinic.
It is not 100% effective. And follow-up
HIV testing is required
