Answer:
True
Explanation:
The deep parts of an ocean receive minimal or no sunlight. Hence, the survival of phototropic organisms like plants and algae is impossible or minimal here. Hence, there is a very little diversity in deep oceans. The organisms living here have to feed on dead decaying matter or on each other for survival. Mostly, the organisms living here use dead organisms as food. No other food source is available here.
Answer:
Somatic cells include a all except skin cells
A)
size = (number of minor spaces x 10μm) / number of ocular spaces
= (2 x 10) / 1
= 20μm
b)Since the RBC has a size of 8μm and the bacterium 20μm, the bacteria is bigger. The Bacterium is bigger than the RBC by 20μm / 8μm
Hence the bacterium is 2.5 times bigger than the RBC.
Answer:
ecosystem, and biosphere
organelle and cells
tissues, organs, organ systems, organisms, populations, communities,
Explanation:
In terms of the hierarchical scales of biological organization, ecosystem, and biosphere are a very large scale, organelle and cells are a very small scale, and tissues, organs, organ systems, organisms, populations and communities, are present between them. The biological levels of organization of living things arranged from the simplest to most complex are organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
