20. A woman has type O blood and her husband has type AB blood. Is it possible for them to have children with the same blood type as their parents? Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter.
21. Can a man with type B blood and a woman with type A blood have a child with type O blood? One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types. For example my father has an A blood type and my mother has an O blood type. My blood type is O+.
22. Cross a man that is heterozygous type A and a woman that is homozygous type B. What percentage of their children will be type AB? There is no chance of a child with Type O. If one parent is AB, there is no chance any child can be O because the AB parent doesn't have a "i" to pass on.
23. Which of the following genotypes results in the same phenotype?
a. IAIA and IAIi c. ii and IBi
b. IAIB and IAIA d. IAIB and IAIA
Anwser: IAIA and IAil

arguments can be made based on the information in the model You may select more than one correct choice.
Answer:
A, D, E
Explanation:
just did it
The arguments that can be made based on the information in the model are as follows:
The mutated DNA is a recessive allele. The mutagen altered the DNA of the worm in the parental generation. The DNA altered by the mutagen occurs in gamete cells and is passed to offspring.Thus, the correct options for this question are A, D, and E.
What is Mutagen?Mutagen may be characterized as a type of agent that possesses the capability to induce mutation within the genetic segment of living organisms. Mutagens are of two types, they are:
Physical mutagens: UV radiations.Chemical mutagens: Chemicals like ethidium bromide.According to the context of this question, mutation can only be inherited from parent to offspring, if it is induced within the gamete cells of parents. While during the course of life, the mutation also induces in the genomic sequence of an individual.
Therefore, the correct options for this question are A, D, and E.

It discourages predators from eating the plant.
It helps the plant reproduce faster in colder environments.
O It helps the plant keep its moisture in hot weather conditions.

-Phosphate-Nitrogen Base
-All sugar molecules
Answer: A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1

There are various symbiotic relationship formed between the organisms present in the environment. These relationships are Commensalism Mutualism, Parasitism, Competition, and Predation. In Commensalism relationship, one organisms gets benefits while the other neither get benefit nor harm. In mutualism, both organisms gets benefits from one another. In Parasitism, one organism get benefits and the other get harmed. In Competition, both organisms cause harm to one another and both are damaged through their actions and in Predation, one organism is benefited by killing the other organism to feed itself.

Which description explains why there are two high and two low tides in a day? (4 points)
Earth moves closer to the sun and moon twice a day.
Earth revolves around the tidal bulges created by gravitational forces.
Earth rotates in and out of a tidal bulge twice a day.
The moon's gravity increases over the oceans and decreases over the land.
Answer:
Earth rotates in and out of a tidal bulge twice a day.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

how is population dynamics affected by water pollution
