The passage of IgG antibodies from mother to fetus illustrates passive immunity.
- Antibodies produced outside the body can protect a person from contracting a disease, or they can give passive immunity.
- Because antibodies are not regenerated as frequently as they would be in a person with a functioning immune system, passive immunity is typically transient.
- Immunity that is transferred from mother to kid is known as maternal passive immunity or natural passive immunity.
- Antibodies are transferred to the unborn child by the placenta while they are still in the womb and can offer protection against the corresponding infections in the weeks and months after delivery.
- An infant's passive immunity to disease is maintained after birth due to antibodies contained in breast milk, particularly in colostrum, the protein-rich milk produced in the first few days after birth.
- The importance of maternal passive immunity for safeguarding infants until their own immune system is mature enough to protect them.

As their name suggest, the light dependent reaction requires light to occur while the light independent reaction can take place with or without light. But the light independent reaction requires the products of light-dependent reaction to start.
1.They reproduce sexually.
2.Their traits are easily observed.
<span>-He formed a five-part hypothesis, a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable.</span>
The answer is; seeds that store energy in sugar
Sugar is the main source of energy for most life. Oils and fats are used to store excess starch energy for later. Therefore seeds that store oil has to re-convert the oils to carbohydrates so as to respire, However, those that store sugars would just retrieve them from storage and directly use them in respiration.
The answer is; YES
Temperature is an important factor in germination and respiration rate. Optimal temperature range will enable the enzymes to be active and hydrolyze stored energy sources (such as oils and carbohydrates) for energy. Higher than optimal temperatures may denature the enzyme while low temperatures will deactivate the enzymes.
