Answer:1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Assume a phenotype is determined by one gene with a dominant allele and a recessive allele. If one parent is homozygous recessiv

d1i1m1o1n [39]

<h2>Phenotype probability</h2>

Explanation:

In the given question,let say A is dominant allele and a is recessive allele
Homozygous recessive parent(having both alleles recessive) will be denoted by aa genotype whereas heterozygous parent(one allele is dominant while other is recessive) will be denoted by Aa
When a cross is made between both the parents then the probability of offspring having the recessive phenotype will be 1/2 or we can say 50%

if a person who is blood type O marries a person who is blood type A, what are the possible blood types their children could hav

Galina-37 [17]

Answer:

The possible blood types their children could have are A or 0.

Explanation:

The I gene determines the blood type of a person. I is the dominant allele, while i is the recessive allele.

IA dominant over i. The person presents A type of antigens.

IB dominant over i. The person presents B type of antigens.

IA and IB are codominant. The person presents both types of antigens, A and B.
i is the recessive allele. The person does not present any antigen.

Cross: a person who is blood type O with a person who is blood type A

Parental) ii x IA-

Gametes) i i IA -

Punnet Square) IA -

i IAi -i

The - symbol represents the possibility of either IA allele or i allele. This is, the parental with blood type A might have the genotype IAIA or IAi

F1) 2/4 = 1/2 IAi

2/4 = 1/2 -i (-i could be either IAi or ii, depending on the genotype of the parental with blood type A)

<u>Option 1</u>: ii x IAIA

F1) 100% IAi (The whole progeny will have blood type A)

<u>Option 2</u>: ii x IAi

F1) 50% IAi (Half of the progeny will have blood type A)

50% ii (Halfa of the progeny will have blood type 0)

The possible blood types their children could have are A or 0.

Answer:

The circuit breaker trips when too much electricity flows through it or when it cannot handle the excess current load. This means that the flow of electricity is cut off to keep your circuits from overheating or causing more damage.

b. When a very strong current passes through it.
