Answer: C) the genes of this phage were made of DNA.
Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.
<span>The lynx population will increase. Then the hare population will drop because they're being eaten by all the lynxes and so the lynx population will drop too because they won't have much food. These things can be modeled with differential equations.</span>
Answer:
a. Through the leaves
Explanation:
the plant absorb carbon dioxide through their leaves.
The correct answer is: B) alcohol-acetone
Gram staining includes next steps:
• Fixation- usually by heating or by using methanol
• Primary stain (crystal violet)- it stains all cells blue/purple
• Mordant- added to form a crystal violet iodine
• Decolorization- distinguishes gram-positive from gram-negative cells. Acetone or ethanol are usually used. Acetone/ethanol extracts blue dye from Gram - bacteria (the lipid-rich, thin wall) more than from the, Gram + bacteria (lipid poor, thick walled). The Gram -bacteria appear colorless and Gram + bacteria remain blue.
• Safranin-the red dye stains the decolorized Gram- bacteria.
Since crop pests damage plants, plants without worms grew better than plants with worms as seen in the graph.
<h3>What is the effect of crop pests on plant growth?</h3>
Crop pests refers to organisms that cause harm to crops as a result of their actions which result in stunted growth or death of plants.
Crop pests usually feed on plant parts such as leaves roots or stems.
Some examples of crop pests include; aphids, worms, termites, etc.
In the graph, the growth of plants with and without worms is compared.
It can be concluded that plants without worms grew better than plant with worms.
