Answer:
Explanation:
The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.
Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.
Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.
Assuming the genotype of the father is AA:
SS x AA
AS AS AS AS
<em>All the children would be normal in this case.</em>
Assuming that the genotype of the father is AS
SS x AS
AS SS AS SS
<em>50% of the children would have sickle cell while the remaining 50% would be normal.</em>
<u>Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.</u>

Answer:
This process of making sugar and oxygen is called photosynthesis. Pond weed uses the carbon dioxide which is dissolved in the water it is in. The amount of dissolved carbon dioxide can be varied by adding sodium hydrogen carbonate (carbon dioxide solution) to the water.

Answer:
Show that life can only come from life (rather than spontaneous generation)
Explanation:
Pasteur boiled a broth in a flask with an S-shaped neck. Thebend in the neck prevented particles from the air reaching the broth, but still allowed air to get in. No bacteria grew in the flask.
When the flask neck was broken so that particles could get inside, the broth became cloudy, showing that microorganisms were only able to grow from other living things from the outside, and not spontaneously from nothing
