Bee hummingbird, zunzuncito or Helena hummingbird (Mellisuga helenae) is a species of hummingbird which is the world's smallest bird and the smallest known dinosaur. It is native to Cuba.
In rheumatoid Arthritis patients, NK cell levels were abnormally elevated, possibly due to high serum levels of IL-2.
Rheumatoid arthritis (RA), is an autoimmune disease that means our own immune system attacks self healthy cells in the body by mistake, causing inflammation (painful swelling),mainly attacks the joints.
The given study is to investigate the relationship between serum interleukin-2 (IL-2) levels and disease activity.
This study also showed the relationship between absolute numbers of peripheral lymphocyte subsets, autoantibodies, and associated cytokines in patients with rheumatoid arthritis (RA).
The results showed that the number and percentage of NK cells were positively correlated with serum IL-2 levels so, IL-2 can be a reason for elevated level of NK cells

Answer:
A solution could be made by listening to each other thoughts and their sides of the story
Explanation:
You did not give me any statements to pick from but if any could relate to this one it will be right I hope this helps :)
Answer:
Simple organisms, such as theamoeba and earthworm, have a moist, permeable external surface. Oxygencan pass into them through this surface by diffusion. A large surface area is needed for effective gas exchange - so larger, more complex, organisms have special organs such as gills and lungs.
Explanation:
Answer: The blank can be filled correctly by "if the seeds contain the gene or allele responsible for large size of the tomatoes"
Explanation:
In plants also, characters or traits of characters are defined by genes. Different alleles produce different traits of the same character.
For example, in classic Mendelian genetics, T was the allele responsible for tall plant trait while t was the responsible for dwarf trait.
Similarly, there would be a gene(s) responsible for size of the tomatoes. In addition, seeds are the products of sexual reproduction of plants. So, they may carry genetic combination different from parent plants (due to meiosis, crossing over, independent assortment, et cetera).
So, if the seed contains the gene or allele responsible for large size of tomatoes then only they will produce same kind of tomatoes.
