What interactions are occurring that allow the water to move against gravity in capillary action? Select three options.

Biology
1 answer:
solniwko [45]2 years ago
3 0

Answer:

Adhesion and surface tension

Explanation:

Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.

Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.

Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.

Susan, a mother with Type B blood, has a child with Type B blood. She claims that Craig, who has
laiz [17]

Answer:

A child with type B blood can have a mother with type B blood and a father with type O blood so the judge grants her request and decides due to Susan is right and Craig must pay child support (option b).

Explanation:

Susan is right in this case because her <u>son with type B blood may have a mother with type B blood and a father with type O blood</u>.

Blood types, according to the ABO system, depend on the existence of surface antigens A or B —Types A, B and AB— or their absence in the erythrocyte membrane.

In the inheritance of blood groups A and B are co-dominant, while the absence of antigens —type O— is a recessive trait.

Assuming that Susan has a genotype B/B and that Craig has a genotype O/O:

<em>Alleles      O     O </em>

<em>B            B/O  B/O </em>

<em>B            B/O  B/O</em>

So it is very likely that the child is Craig's son and Susan is right.

muminat

Answer:

The researchers' experimental hypothesis was that changes in actin and myosin overlap would alter the number of myosin cross- bridges that could form within a sarcomere, and specifically that (Primer Section Key Terms O)

A. Increases in overlap favor more cross-bridges to form, increasing muscle force. muscle force. effect on muscle force. fiber) lengths.

Explanation:

Physiologists Alfred Gordon and Fred Julian and Andew Huxley investigated on the strianed muscle´s contraction properties, to demonstrate the way the muscle lenght is affected by changes in overlap between myocin and actin causing the number of cross-bridges increase , increasing muscle´s force as well.

No cross-bridge disruption is caused, nor litlle differences or minimal overlap so B, C and D options are not correct.

which statement describes only one way that RNA differs from DNA? a. one is a protein, and the other is a nucleic acid. b. they
zalisa [80]

DNA stands for Deoxyribonucleic acid which means it is a nucleic acid. RNA stands for Ribonucleicacid. RNA produces proteins


DNA replicates and stores genetic information.

RNA converts the genetic information contained within DNA to a format used to build proteins.


I would have to say the answer is A based off the information above.


Please correct me if I'm wrong.

There was ________ years between the heliocentric theory and geocentric theory
MaRussiya [10]

Answer:
