The characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat
<h3>What are viruses?</h3>
Viruses are microscopic non-cellular structure consisting of a core of DNA or RNA (nucleic acid) surrounded by a protein coat (capsid).
A virus is considered as by non-living because it requires a living host cell to replicate, and often causes disease in the host organism.
Therefore, the characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat

Answer: allele, gene, DNA, chromosome, nucleus
Explanation: An allele is a variant of a gene or a different form of a gene. A gene is a segment of a DNA that codes for an RNA or a protein. A DNA is a genetic material that contains all the genetic information of an organism. A DNA is packaged and condensed into a threadlike material known as chromosome and chromosomes are found in the nucleus of a cell.
Mangrove forests were traditionally viewed as A. unproductive wastelands. People therefore reasoned that their removal would improve the health of their ecosystems, leading to their degradation.
Course alteration is the first to be utilized to find the example, and just with the low power objective. When seeing an example, you should dependably utilize the lower control target focal points first. Low power focal point gives the most stretched out field of view and makes it less demanding to discover the example when you look through the magnifying lens. Finding the example at high power, without first focusing it in the field of view at low power, is almost outlandish.
