Answer:
option c. viroid control
Explanation:
The chestnut tree in Europe is infected by a fungus called <em>Cryphonectria parasitica </em>that<em> </em>causes a disease called chestnut blight. The disease is controlled by a biological control method called hypovirulence.
The hypovirulence is a virus that attacks the fungal pathogen (<em>Cryphonectria parasitica </em><em>)</em> of chestnut tree. This fungal virus decreases the ability of fungal pathogen to cause chestnut blight disease. This technique prevents the chestnut plant after huge destruction of it in Europe.
The pathogen that have virus is introduced naturally over the plant. This reduces the infection and allows the natural growth of trees. Thus, option C is correct.
Answer:
Asexual is reproduction with one parent (single celled organisms)
Sexual is reproduction with two parents
Explanation:
<h2>
<u>Asexual reproduction</u> </h2>
is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaebacteria, eubacteria, and protists.
<h2>
<u>Sexual Reproduction</u></h2>
Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells.
