Answer:
250 nm
Explanation:
Data provided in the question:
Length of the bacteria cell = 2.5 micrometers (µm)
Now,
We know that,
1 m = 10⁶ µm
or
1 µm = 10⁻⁶ m
also,
1 m = 10⁹ nm
or
10⁻⁹ m = 1 nm
Therefore according to the above results we get,
2.5 micrometers (µm) = 2.5 × 10⁻⁶ m
and,
2.5 × 10⁻⁶ m = ( 2.5 × 10⁻⁶ ) × 10⁹ nm
= 2.5 × 10³
= 250 nm
Phycomycetes is an obsolete[1][2][3] polyphyletic taxon for certain fungi with nonseptate hyphae.[4] It is used in the Engler system.[5]
The class Phycomycetes has been abolished and in its place exists Zygomycetes, Chytridiomycetes, Plasmodiophoromycetes, Hyphochytridiomycetes, Trichomycetes (including Harpellales, Asellariales, Eccrinales and Amoebidiales) and Oomycetes. Still, "Phycomycetes" can be used to refer to all the above-mentioned classes as a whole.
The members of this group are found in aquatic habitats and on decaying wood in moist and damp places or as obligate parasites on plants. The mycelium is aseptate and coenocytic. Asexual reproduction by zoospore or by aplanospore. A zygospore is formed by the fusion of two gametes. Examples are <em>Mucor</em>, <em>Rhizopus</em>, and <em>Albugo</em>.
The guidelines suggest 3 to 5 servings of vegetables a day
Answer:
1) Stem cells can renew themselves by dividing into more stem cells more than once.
2) There are two types of stem cells: adult and embryonic stem cells.
3) Stem cells are not specific to one area in the body and can turn into skin, bone, blood or brain cells.
