Answer: Rheumatoid Arthritis
Explanation:
In patients suffering from rheumatoid arthritis, accumulation of urates occur in the joints due to the deficiency of a vital enzyme, as a result the immune system produces antibodies that attack these joints or organs where urates are found.
This eventually leads to inflammation & degeneration of the joints, characterized by painful swelling and stiffness
Answer and Explanation:
<u>Available data:</u>
- New breeding occurred between two different cats.
- Both cats were heterozygous hairy cats,
- One parent loved sinks and the other parent disliked sinks.
Let us say that:
- the gene for the cat hair trait is H, being "H" the dominant allele expressing hair, and "h" the recessive allele expressing hairless.
- the gene for the sinks-liking trait is S, being "S" the dominant allele expressing sinks-liking, and "s" the recessive allele expressing sinks-desliking
If both cats are heterozygous for the hair trait, then their genotypes would be Hh in both animals.
One of the cats likes sinks, so its genotype would be S-. The "-" symbol means that we do not know if this is a homozygous or heterozygous animal. The other cat disliked sinks, so its genotype for the trait would be ss.

a) List the genotype of each parent based on the information above.
Parent 1: HhS- ---> there are two possibilities: HhSs or HhSS
Parent 2: Hhss
b) Determine how many of the potential offspring would be hairless and love sinks
If parent 1 is HhSs, the potential offspring that would be hairless and sinks-loving would be 2/16=1/8. Its genotype would be hhss.
HS hS Hs hs
Hs HHSs HhSs HHss Hhss
Hs HHSs HhSs HHss Hhss
hs HhSs hhSs Hhss hhss
hs HhSs hhSs Hhss hhss
But if parent 1 is HhSS, there would not be any individual hairless and sinks-loving. All of them would be heterozygous for sinks-liking.
HS hS HS hS
Hs HHSs HhSs HHSs HhSs
Hs HHSs HhSs HHSs HhSs
hs HhSs hhSs HhSs hhSs
hs HhSs hhSs HhSs hhSs
Answer:
The alleles for MADS-box genes get expressed at different levels. They form the “L” complex and the “SP” complex. These are a group of proteins that determine the shape of the petals. The more they L complex is expressed, the high the probability that the petals of the flower will form the ‘lip’ and the high the SP complex is expressed then the high the likelihood of dominant petals.

Answer:
Humans participate in 1 and 3, so the answer is C. We burn fossil fuels and use our respiratory system to produce carbon. We do not, however, go through photosynthesis like plants.
