I think it would be phase 1 (sorry if I’m wrong)
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.

Nature refers to your genetic predisposition to be a certain way and nurture refers to the effects that our parents or people who raised us have on us
Answer:over time as our evidence improves. The more experiments we do, and the more data we collect, the better our scientific ideas become.
Explanation:
Answer:
See the answer below
Explanation:
The Chi-square (
) is calculated by the formula:
= 
where O = observed frequency and E = expected frequency
A standard dihybrid cross is expected to give 9:3:3:1 phenotypic ratio.
Phenotype O E
Round yellow 104 9/16 x 160 = 90 
= 2.18
Round green 27 3/16 x 160 = 30 
= 0.30
wringled yellow 27 3/16 x 160 = 30 = 0.30
wrinkled green 2 1/16 x 160 = 10 
= 6.40
Total value to two decimal places = 9.18
Degree of freedom = (n-1) = 4 -1 = 3
Critical value at 95% probabillity level = 7.815
<em>Since the calculated </em><em> si more than the critical </em><em> value, </em><em>the null hypothesis is rejected. </em>
