The correct answer is I and IV
In the Basidiomycetes, the spores are produced externally on the end of specialized club-shaped structure called basidia. Whereas, In ascomycetes, spores are produced internally, in the sac-like structure called an ascus. Some members of ascomycetes cause plant diseases such as powdery mildew of grape (<em>Uncinula necator</em>), chestnut blight (<em>Cryphonectria parasitica</em>), and apple scab (<em>Venturia inequalis)</em>. Memers of basidiomyctes cause smut of corn (<em>Ustilago maydis</em>), brown root rot, and coffee rust.
Answer:
controlled experiments
Explanation:
Experiments in which all variables are identical except for one are called controlled experiments. This where an observer tests his hypothesis by looking on changes that were brought about by one variable. The results are always dependent on one adjusted variable.
Answer is a. he projections are trichocysts, released for the self-defense of the <em>Paramecium</em>.
When <em>Paramecium</em> is stimulated by chemicals such as picric acid or an injurious enemy, it responds by throwing out transparent spine-like projections called trichocysts. The discharge of trichocysts forms an effective barrier round the animal and protects it from acid or enemy.
The use of restriction enzymes is evidenced by the statement 'cut site mCYCF3E 685' (Option A).
<h3>What are restriction enzymes?</h3>
The restriction enzymes are proteins (enzymes) that cut specific sites in the nucleotide sequence.
In this case, the enzyme cuts the gene mCYCF3E at the position number 685 (nucleotide base).
In conclusion, the use of restriction enzymes is evidenced by the statement 'cut site mCYCF3E 685' (Option A).
