Answer:
As a cell grows in size, the surface area gets bigger, but the volume gets bigger faster. Thinking about this as a ratio (division), the volume is the denominator and the surface area is the numerator. If the volume is getting very big, then the ratio itself will be getting very small.
Answer: Drainage or absorption of amniotic fluid
Explanation: Amniotic fluid act as a cushion to a growing foetus and provides the foetus with nutrients and biochemical products from the mother via the blood vessels of the placenta. When the date of baby delivery grows closer the lungs absorbs some of the fluid. Soon after birth the newborn's first step to independence begins with breathing on its own.They gasp and cry taking in air that fills the lungs. This expels the remaining amniotic fluid that was in the lungs and begins its own independent breathing.
<h2>Active and Passive Immunity</h2>
Explanation:
- Immunity can be obtained distinctly and Recovery from clinical tetanus doesn't bring about assurance against future disease by <em>active or passive immunization</em> and recovery from the clinical<em> for example, immunization, immunoglobulin treatment, or move of maternal antibodies through the placenta</em>
- Active inoculation stimulates the <em>immune system to deliver antibodies against a specific irresistible specialist</em>
- <em>Active immunity</em> can emerge normally, as when somebody is presented to a pathogen.<em> For example,</em> a person who recuperates from a first instance of the measles is <em>insusceptible to advance immunity</em>
