The correct answer is:
A. leaves and dermal
Explanation:
The dermal tissue system protects the soft tissues of plants and handles interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells comprising the younger parts of a plant. It conceals a waxy layer named the cuticle that inhibits water loss. Plant parts that become woody no longer have dermal tissue as their outer layer because it is followed by periderm or cork. Just as our own covering assists to defend our bodies, the dermal layer of a plant has the same function.
Viruses are at the heart of this century-old debate. Viruses<span> are parasites that infect plants, animals, fungi and bacteria. They consist of genetic material surrounded by a protein coat and are unable to grow or reproduce without a host. The classification of viruses has confused scientists for nearly 100 years. Originally they were viewed as poisons. In fact, the word ''virus'' is Latin for ''poison.'' They have since been viewed as living creatures, then mere bio-chemical compounds, and, most recently, somewhere in between chemical compounds and lifeforms.</span>Non-cellular life<span> refers to organisms, such as viruses, that exist without any cells, and it is a very controversial topic. The cell theory, which is one of the fundamental tenets of biology, states that all living things are composed of cells and that cells are the basic units of life. So the idea that something can be considered alive without having cells is an issue that is up for debate.

Complete question:
A researcher had 15 pure-bred wild mice which were brown and all were females. They were all mated with a male called Bob. All the offspring were brown. These were then crossed among themselves with the following results: 293 brown and 115 white.
(i). Determine the color of Bob.
(ii). Determine which color is dominant.
(iii). Work out the ratio of brown to white in the ‘grandchildren.’
(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring.
Use the Punnett square to work out your answers
Answer:
(i). Determine the color of Bob. BOB IS WHITE
(ii). Determine which color is dominant. BROWN IS DOMINANT
(iii). Work out the ratio of brown to white in the ‘grandchildren.’
PHENOTYPIC RATIO BROWN TO WHITE 3:1
(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring. THE WHOLE PROGENY WILL BE WHITE
