fungal and protist infections, especially those that are deeper than the skin, are especially hard to treat. why?​
matrenka [14]

Answer and explanation:

Fungi and protists are eukaryotic. However, antibiotics selectively targets prokaryotic cells. Thus, the use of antibiotics for the treatment of fungal and protist infection is of no use at the first place. Secondly, if we use the other medicines that could kill the fungi/protists (e.g. fungicides), they could also kill the host's cells (animal's cells). This become further difficult if the infection is deeper in the skin. This is because, we would not be able to apply the medicine as direct application on skin but would give either intravenous or via food. This would increase the chance of imacting negatively the other organs/cells. The only option in such scenario is the surgery, which cannot be 100% effective because some spores may left even after the treatment.

Water is drawn upward from the roots through plant tissue to the leaves by ________.
Assoli18 [71]

Answer: a. capillary action.

Water is a taken up by the plants from the roots, which needs to be transferred to all the parts of the plants to conduct cellular metabolic processes like photosynthesis and respiration. The properties of water molecules are responsible for conduction of water from the root to the stem and other higher parts. The cohesion is the property of water which water molecules are combined with each other due to sharing of bonds at the atomic level. The adhesion is the property of water which allows water molecules to attach with other substances or substrate.  Adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. Capillary action occurs when the adhesive force is greater than the cohesive force between water molecules. The supply will be upward and force of gravity will also be applicable on this. Capillary action mimics the transfer of water from a tube or pipe. In this way water is drawn upward from the roots through plant tissues to the leaves by capillary action.

Radda [10]
<span>I belive the answer is D. Burbank's process did not involve environmental pressures to shape the outcome. 

Burbank process is similar to natural selection because he will select the potato based on some traits. The trait would be big potato and resistant to disease. The genetic makeup will also favor those with the selected trait. This process should be faster.</span>

Which part of a green plant makes most of the plants food?
ikadub [295]

Answer:

Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose which is sugar. This energy rich sugar is the source of food used by most plants.
