Answer:
the rate of change of velocity with time is called acceleration.
it can also be defined as the increase in velocity per second.
The S.I. unit of acceleration is meter per second square or ms−2.
formula; a = Δv / Δt
where a is acceleration,
Δv is the change in velocity,
and Δt is the amount of time it took for that change to occur.
No it shouldn’t, it should be lead by the purity of someone and the genuine intent of good purpose.
A cell is the smallest life unit
Answer:
Yes; this difference from bacteria is unimportant, because the many similarities between bacteria and mitochondria provide sufficient evidence in favor of the hypothesis.
Explanation:
The passage speaks about the protein synthesising ability of bacteria and mitochondria. The bacteria are single-celled microorganism and they are prokaryotic. They lack membrane bound organelles such as mitochondria. But both mitochondria as well as the bacteria has certain similarities.
The structural similarities between the cell organelle and the organism shows favourable evidence that most proteins in present-day mitochondria are made by cytoplasmic ribosomes from mRNA transcribed from nuclear genes.
I) According to FDA there are about 38 toxic contaminants of bottled water may include, Chloride, Coliform, Arsenic, Iron, Manganese, phenols, Dissolved solids, Zinc,and Flouride. It is the work of FDA to allow certain levels of these contaminants in bottled water. Higher levels than the recommended levels may be toxic and dangerous to human beings.
ii) These contaminants are from different sources, for example chloride ions or chlorine is from the disinfectant used to treat water since the compounds are chloride compounds and also other byproducts of chlorine based disinfection. The CfCs is from the plastic making the bottle if water is exposed to sunlight.
