Answer:
Bar graph.
Explanation:
But what are you wanting to do? That might help.
Answer:
She should ensure that subjects are randomly chosen from the sample group to prevent biases. She should ensure that there are no confounders in her study or that confounders are accounted for, for example, age or year of study. Older students would be more likely to consume alcohol and also be more likely to have better academic performance, for example.
That phrase is an example of Alliteration.
The correct answer is: There are 20 primary teeth, and by 24 months of age most children have all 20.
Primary teeth also known as deciduous teeth, milk teeth, are the first set of temporary teeth in the growth development of humans. They develop during the embryonic stage of development, become visible in the mouth during infancy (erupt) and usually get replaced by permanent teeth around age six (the first tooth). The primary teeth consist of 4 central incisors (one in each quadrant), 4 lateral incisors, 4 canines, 4 first molars, and 4 secondary molars.
A) Scale: 1 mm² = 1 organism
The base of the pyramid will be a square that is 1 mm by 1 mm
The next tier of herbivores will be 100 mm by 100 mm
The next tier of carnivorous insects and spiders will be 50 mm by 10 mm
The final tier of birds will be 3 mm by 1 mm
b) Biomasses:
Tree = 4000 kg
Herbivores = 10,000 x 0.05/1000 = 0.5 kg
Carnivores = 500 x 0.2/1000 = 0.1 kg
Birds = 3 x 10/1000 = 0.03 kg
Scale: 1 mm² = 0.1 kg
The bottom tier will be 400 mm by 100 mm
The next tier will be 5 mm by 1 mm
The next tier will be 1 mm by 1 mm
The final tier will be 0.3 mm by 0.1 mm
The pyramid of numbers and pyramid of biomass are the opposites of one another because energy is lost as we go up the tiers of a food pyramid. Only 10% of the energy in a trophic level is passed to a higher one. This is why the overall numbers may increase, due to smaller organisms, but the main place where organisms utilize energy, production of biomass, reduces drastically.
