Answer:
They’re perfect for growing all kinds of greens like lettuce, spinach, peppers, tomatoes, flowering crops in the vegetative stage and many others.
Neon is a member of the noble gas family. Other elements in this family includes <span>helium, argon, krypton, xenon, </span>and <span>radon. </span>These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.
Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.

Answer: B) The experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Explanation:
The most logical third step in Connell's experimental procedure, permitting him to either accept or reject his hypothesis of competitive exclusion is the experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Balanus is a species of crustacean, as know as sea acorns, whereas Chthamalus is a species of barnacles that can easily be found in the northern hemisphere's coasts.
Answer:
Replicate itself into the cell host
Explanation:
Visus is made from a protein capsule and inside a fragment of RNA. Sometimes they also have some feet of filament to get attached to the cellular membrane.
Once attached, the virus injects its RNA into the cytoplasm and travels to the nucleus and insert this fragment of RNA into the cell DNA and start making copies of itself.
When the cell is full of virus, the membrane breaks and releases all the new virus to the neighbor cells, and the process starts again.
Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
