Answer: DNA bases are A,T,C,G and here we have U which is not a DNA base therefore being an RNA strand. RNA bases are A,C,U,G.
Answer:
C
Explanation:
Hyphae is the vegetative growth of fungi.
it is long and filamentous in nature and is
analogous to the rhizoids of runner plants. A
network of many crisscrossing hyphae is called
mycelium, When a hyphae branches vertically
upwards to give rise to a sporanguim, it is
called sporangiophore (such as the case in
the attached diagram

Explanation:
Meiosis is known to be a process of reducing the number of chromosomes in a diploid to half.
And it should be noted that , meiosis requires the pairing of two chromosomes sets.
Therefore in this case, before meiosis can occur in the haploid, it must involves two haploids. This means that two individual haploid will fuse together to form diploid meiocyte, which will allow meiosis to occur.
This is the reason why meiosis can only takes place on haploid species.
In summary, it should be noted that, meiosis can only takes place in a diploid and two individuals haploid [ haploid species] that can fuse together to form diploid, but not in a haploid individual.
Answer:
If a neurotransmitter attaches to a ligand-gated channel and creates a potential that causes the inside of the excitable cell membrane to become less negative, and this potential travels only a short distance before dying out, it is considered to be a <u>Graded or local potential</u>
Explanation:
<em>Graded potentials, also known as local or generator, are generated by an excitatory neurotranmitter, usually a ligan gated channel</em>, they occur at a localized place on the cell and their potentials are smaller (from 1-50mV) and its magnitude depends on the strength of the stimulus.
