Answer:
D
Explanation:
Because if you look at the pattern and location of each shading you cant tell that they are the exact same. No 2 people have the same fingerprint hence that has to be from the same person.
Hope it helps
Cutting down trees results in loss of habitat for many animals in the wild, because over 70% of animals that live on land live in trees! Cutting down trees can also reduce our oxygen.
Answer:
1 DDRR - Red, non-dexter
2 DDRr - Roan, non-dexter
2 DdRR - Red, dexter
4 DdRr - Roan, dexter
1 DDrr - white, non-dexter
2 Ddrr - white, dexter
Explanation:
Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.
Roan are also heterozygous.
If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.
If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.
Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.
Crossing the two: DdRr x DdRr
Progeny:
1 DDRR - Red, non-dexter
2 DDRr - Roan, non-dexter
2 DdRR - Red, dexter
4 DdRr - Roan, dexter
1 DDrr - white, non-dexter
2 Ddrr - white, dexter
<em>Others that are either aborted or stillbirths include:</em>
<em>1 ddRR </em>
<em>2 ddRr </em>
<em>1 ddrr</em>
Answer:
You did not write the concept, so i will try to answer in a general way.
Why sometimes we really need to model concepts?
Well, sometimes the things are really complicated, or we just do not have the knowledge or tools to fully understand them.
Here is where the models came to be handy, we can somewhat "simplify" the things, and explain them with models.
For example, the movement of a particle as the wind pushes it can be really complex, so this can only be explained with a model.
Now, once we have a model (supported by theory and experiments) we can start to investigating furthermore in the given subject.
So for example, we could model how a given therapy acts on a given disease, and with that model, we could extrapolate the effects of the therapy in a similar disease (for example, testing how radiotherapy acts on a given tumor in some organ, can give information on how the same therapy can act on other types of tumors)
Concluding, models simplify some concepts, which allow us to understand them and work better with them
