Answer:

This compression increases the pressure inside cooker to more than atmospheric pressure which in turns increases the boiling point of the remaining water.

Explanation:

This compression increases the pressure inside cooker to more than atmospheric pressure which in turns increases the boiling point of the remaining water. ... Higher temperature of water means higher transfer of heat to food kept in it and hence the faster cooking.

In corn, small pollen (sp) is recessive to normal pollen (sp+) and banded necrotic tissue, called zebra necrotic (zn), s ssive t

alex41 [277]

Answer:

Option B

Explanation:

Please see the attached image

Given -

Allele for small pollen is "sp"

Allele for normal pollen is "sp+"

and "sp+" is dominant over "sp"

Allele for zebra necrotic tissue is "zn"

Allele for normal necrotic tissue is "zn+"

and "zn+" is dominant over "zn"

Cross is carried out between

sp+ sp zn+ zn x sp+ sp zn+ zn

The gametes of the parent cells are -

sp+ zn+, sp+zn, spzn+, spzn

The cross would be as follows

sp+ zn+ sp+zn spzn+ spzn

sp+ zn+ sp+ sp+ zn+ zn+sp+ sp+ zn+ znsp+ sp zn+ zn+ sp+ spzn+ zn

sp+zn sp+ sp+ zn+ znsp+ sp+ zn znsp+ sp zn+ zn sp+ sp zn zn

spzn+ sp+ sp zn+ zn+sp+ sp zn+ znsp sp zn+ zn+ sp sp zn+ zn

spzn sp+ sp zn+ zn sp+ sp zn zn sp sp zn+ zn sp sp zn zn

Hence, option B is correct

A student claims that the four types of macromolecules make up all of the

svet-max [94.6K]

I will support the notion that the human body is made up of the four types of macromolecules which can be seen below:

Carbohydrates.

Lipids.

Proteins.

Nucleic acids.

<h3>What is a Macromolecule?</h3>

These are referred to the large molecules which are involved in the biochemical activities of the body and examples include protein, lipid etc.

All cells in the body however contain all the macromolecules because Protein acts as the building block for the cells while carbohydrates are usually stored in cells as glycogen. Lipids form part of the membrane and nucleic acids such as DNA are present in all parts of the body.

One parent has type A blood and the other has type B. What are their genotypes if they produced children whose blood types were

zhenek [66]

Answer:

iAiA and iBiB

Explanation:

Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:

iAiA or iAi - type A

iBiB or iBi - type B

iAiB - type AB

ii - type O

According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.
