Answer:

YES. This information is enough to assume that neither of the blood groups dominates over the other one.

Explanation:  

<u>Available data:</u>

  • A man with blood group B ----> Genotype IBIB or IBi
  • A woman with blood group AB ---> Genotype IAIB
  • Their daughter has blood group AB --> Genotype IAIB

The fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.

  • If blood type B was dominant over A or AB, then the daughter should have Blood type B.
  • If blood type A was dominant over B or AB, then the daughter should have Blood type A.
  • Blood type AB tells us that both types are being expressed, A and B.

The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.

This is enough information to assume that neither of the blood groups dominates over the other one.

Regarding human traits, which individual would most likely agree with aristotle?
fiasKO [112]

Regarding human traits,  Locke would most likely agree with Aristotle.

There are more areas where Aristotle and Locke's philosophical views diverge than where they concur. For instance, Aristotle once claimed that a person's happiness was just as important to them as it was to their political community. The political understanding of Locke, however, is different because, in his view, a government only assumes responsibility for a portion of the human rights that it is meant to protect in accordance with what people deem to be right. Individuals are therefore given priority because they have rights that are inalienable and shouldn't be manipulated by people to fit their agenda. These and other traditional philosophies have been used to analyze and comprehend early philosophy.

Answer:

Due to cell wall.

Explanation:

Scientists were able to easily  identify the cells in plants first as compared to animal cell because the plant cell has cell wall while the animal cell has no cell wall only cell membrane. The structure of plant cell is just like the compartments and the cell wall provides the boundary between two cell which enable the scientist to see the plant cell first.

Is ductility considered as a physical property or a chemical property
Elena L [17]

Ductility is a physical property.

A physical property of a material is a property that can be measured or observed without changing the composition of the material.

In this case ductility is a physical property. It is defined as the  property of a material associated with the ability to be drawn or stretched into a wire without breaking. The chemical identity of the material is not affected, that is  it does not change.

Example of ductile materials include gold, silver, copper, erbium, terbium and samarium.

Other examples of physical properties are:

1. Solubility

2. Melting point.

3. Boiling point.

4. Color

5. Density.

Are birds more closely related to mammals or to reptiles
Zepler [3.9K]
Mammals. I am no scientist, but I think that they are closer to mammals due to the fact that they are warm-blooded, and they raise their young. Reptiles are cold blooded and usually leave their offspring to fend for themselves.
