Answer:
There was no change in the number of days with poor flower availability
Explanation:
When replicating a study, the researcher develops the exact same study (experiment/treatment) in different places (experimental unit). In this case, as the researcher replicates the study in the Appalachian Mountains and gets similar results, that means that there was no change in the number of days with poor flower availability.
Answer:
The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen ... It sends out an electrical signal to start the contracting (pumping) of the heart muscle.

22 pairs of autosomes, 1 pair of sex chromosomes, I notice that the X and Y chromosomes are sex chromosomes and that they are different in length and size., The sex of this organism is male, as the genotype XY can only mean a male gender; female gender is denoted by the genotype XX., You didn't put in Karyotype A., The special circumstance is with group 21 of chromosomes. There are 3 instead of 2 in that group., This circumstance results in a condition known as trisomy 21, or Down Syndrome. Down syndrome causes a distinct facial appearance, intellectual disability, developmental delays, and may be associated with thyroid or heart disease.
, Name the karyotype "Down Syndrome Karyotype?" (I'm not sure on the last one)

Peyer's patches (aggregated lymphoid nodules)
Explanation:
Peyer's patches are anatomical regions located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine. These patches are nodules or cumulus of lymphatic tissue and other accessory cells, and this is why they represent a huge part of the mucosa´s immunity system.
Peyer's patches belong to the group of lymphoid tissue associated with the intestine, composed of lymphoid follicles distributed along the gastrointestinal tract.
A lymphoid follicle is a cumulus or aggregate of lymphoid cells that do not have a well-defined structure nor organization. In general, these follicles are isolated from each other in the intestine. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque. The Peyer´s patches are formed principally by lymphocytes B that synthesize immunoglobulin A, which has an important role in immunity.
