Answer:
The correct answers are B and C. Walter Sutton and Theodor Boveri were the first to suggest that growth of cancerous cells was a result of abnormal chromosomes.
Explanation:
The chromosomal theory of inheritance is a scientific theory that relates chromosomes with the transmission of inheritable characters. It is also called the chromosomal theory of Sutton and Boveri in honor of the two people who independently developed it in 1902, Theodor Boveri and Walter Sutton. This theory states that the alleles, the Mendelian genetic factors, are on chromosomes.
Theodor Boveri and Walter Sutton independently developed the chromosome theory in 1902, Boveri, studying embryonic development in sea urchin and Sutton in this work on meiosis in grasshopper.
Sutton and Boveri's proposition in 1902 that chromosomes are the factors of Mendelian inheritance was controversial until its demonstration in 1915 by the work of Thomas Hunt Morgan in the Drosophila melanogaster fly.
Answer:
negative feedback loop involving insulin and glucagon help to keep blood glucose levels within a narrow concentration range. If glucose levels get too high, the body releases insulin into the bloodstream.

Betta fish are also known as Siamese fighting fish.They flare their gills when they are ready to fight. This makes them appear larger since fish do not have very good eyesight. They also fan their gills when they are trying to court a female Betta. ... Bettas are one of the few fish that can get air from above the water.
Answer:
C) Interaction increases the survival and reproductive rates of mutualistic species.
Explanation:
A) Mutualism offer more biodiversity to a community.
Biodiversity is the different species living in one environment. Since mutualism is only involving two species, it wouldn't increase the biodiversity of one ecosystem, making it incorrect.
B) Individuals partaking in a mutualistic relationship relationship are more resistant to parasites.
Mutualism is only benefiting two species, not their immunity to diseases and parasites. These two have no correlation with each other, making it incorrect.
D) Mutualistic interaction lessens competition in communities where it is present.
Since mutualism is only benefiting two species, they have no correlation since the relationship doesn't affect the different species in the environment.
E) Mutualistic relationships allow organisms to synthesize and use energy more efficiently.
Although there could be some relationships involving energy transfer between the species, that would sound more like commensalism or even paratsitism if you think about it. However, it is very uncommon and usually energy has no relationship with species relationships, making it incorrect.
Hope this helps! My deepest apologies if I got in incorrect!
