Answer:
There you have it. Jill's parents are IAi & IB
Explanation:
one brother: Type B, one of the parents must have the IB allele
other brother: Type A,
other parent must have the IA allele & have a genotype of IAi.
Jill's parents are IAi & IB
Jill's parents have the genotypes IAi and IBi.
What is blood type?Blood type refers to the classification of blood based on the presence or absence of certain antigens on the surface of red blood cells. The most common system used for classifying blood types is the ABO system, which has four types: A, B, AB, and O.
If Jill's blood type is O, then she inherited an O allele from each of her parents. Since her two older brothers have blood types A and B, we can conclude that her parents are both heterozygous for the A and B alleles (IAi and IBi). This means that each parent contributed an i allele to Jill, resulting in her blood type O.

Explanation:
Which prediction will most likely describe how friction will affect her findings? The distance for Trial 3 will be greater than the distance for Trial 1 partly because the weight difference of the balls will affect friction. The distance for Trial 2 will be greater than the distance for Trial 1 because the difference in surface roughness will affect friction. The distance for Trial 4 will be greater than the distance for Trial 2 partly because the weight difference of the balls will affect friction. The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.

The _____ refers to the specific combination of versions of genes that an organism has inherited.
A. Genotype
B. Phenotype
C. Chromosome
D. Allele
Answer:it’s genotype
Explanation:
A. Genotype
Genotype of an organism refers to its genetic makeup. By genetic makeup, it is meant that the genes responsible for specific traits that are inheritable. Genes in an organism are often in alternate versions called ALLELES.
Two or more ALLELES make up a gene. Hence, all the alleles of an organism refers to that organisms GENOTYPE. According to this question, the specific combination of versions of genes (ALLELES) that an organism has inherited is a GENOTYPE.

What trends do you see with regard to CO2 concentration? What about average global temperature trends?
Answer:
The CO2 concentration in the air increased, and temperatures increased too.
Explanation:
PLATO answer
The temperature change shows a relationship with the carbon dioxide concentration in the atmosphere. The carbon dioxide concentration in the air increased, as a result the temperature of the atmosphere increased too.
What are the global temperature trends?The global temperature trend is the average rate of increase or decrease in the temperature at the grid points over the specific time period of interest. Global temperature trend is determined by the simple linear regression through the data which is available for each of the grid points. These are expressed in degrees Celsius per decade.
The carbon dioxide concentration in the atmosphere shows a linear relationship with the temperature of that region. When there is more carbon dioxide in the atmosphere, it makes the atmosphere warmer through heat trapping. Since, humans are adding more carbon dioxide the atmosphere continuously, that helps to explain why the temperatures are increasing around the world continuously.

How do choroplast in guard cells control the turgidity of the guard cells. Controlling the stoma. (i know that water flows in and the guard cell becomes turgid, but how does the guard cell control the water flow?)
Answer:
The correct answer is letter A. Potassium makes guard cells become turgid when water flows within this protective barrier. This happens so that the plant can perform photosynthesis even without the presence of direct sunlight. The pores of the cells start to contract and conserve water so that the plant can use it later on.
