Obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. Typically, the idea was that certain forms such as fleas could arise from inanimate matter such as dust, or that maggots could arise from dead flesh.
The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus.
A single piece of coiled DNA is called a plasmid.
Osmosis occurs as water can cross the lipid bilayer through specialized channels for water movement called aquaporins.
Aquaporins are integral membrane water channels which form tetramers and have a function in transport of water between cells. <span>Mutations in aquaporin genes have been associated with several human diseases, for example, diabetes insipidus.</span>
Answer:
Tt - 1/2
tt - 1/2
Explanation:
<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>
Tt x tt
Offspring = Tt Tt tt tt (50% tall and 50% short)
If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):
Tt x tt
Offspring = Tt Tt tt tt
Genotype ratio = 2Tt:2tt
Hence,
Tt = 1/2
tt = 1/2
