Answer:
Based on their body <u>structure</u><u>,</u> flatworms and rotifers were not thought to be closely related. However, <u>bilateral symmetry and body texture</u><u> </u>showed that they are a <u>soft-bodied</u> group.
Explanation:
- Flatworm belongs to phylum Platyhelminthes and Rotifera belongs to phylum Rotifera.
- Their body structure may be different but both of them have a bilaterally symmetrical body.
- Both are aquatic animals.
- Flatworm is made up of ectoderm endoderm and mesoderm and has circular and longitudinal muscles. Rotifera is made up of skeletal and visceral muscles. So, they are soft-bodied animals.
course of action is obtain a tube of water filled to the same volume to place across from the specimen

Why do blood samples need to be centrifuged?</h3>
The effect of heparinized blood sample centrifugation time on clinical chemistry and immunology results has rarely been studied. The WHO recommended a 15-minute centrifugation time without citing any scientific publications. The time spent centrifuging has a significant impact on the turnaround time.
On a Roche Cobas 6000 system, we examined 74 parameters in samples from 44 patients to see if there was a statistically significant difference in test results between specimens centrifuged at 2180 g for 15 minutes, 2180 g for 10 minutes, or 1870 g for 7 minutes. For each centrifugation condition, two tubes with different plasma separators (both Greiner Bio-One) were used. Deming fit was used to make statistical comparisons.

Answer:
It is caused by infection with protozoan parasites belonging to the genus Trypanosoma. It is a vector-borne parasitic disease transmited by the Tse-tse fly.
Explanation:
African sleeping sickness, named human African trypanosomiasis, is a vector-borne parasitic disease transmited by the Tse-tse fly (that belongs to the Glossina genus). These flies can acquire the parasite by biting infected humans or animals.
The causative agent is a protozoan of the genus Trypanosoma,
It is caused by infection with protozoan parasites belonging to the genus Trypanosoma. It can be Trypanosoma brucei gambiense or Trypanosoma brucei rhodesiense. Trypanosoma brucei gambiense has a prevalence of 98% of the reported cases, while Trypanosoma brucei gambiense accounts for the 2%.
It accelerated your heart rate so you feel as if you’re in a rush/ need to rush, you’ll feel tense, your pupils dilate to let more light in to see better in darkness, your digestion rate decreases, more blood flows to your muscles so you can fight or take flight (run away)
