Covalent Bonds: A Hydrogen Example. A covalent bond is a chemical bond that comes from the sharing of one or more electron pairs between two atoms. Hydrogen is an example of an extremely simple covalent compound. A hydrogen example.
The root cap is a small structure but one that serves a very important function for a plant. Protecting the root apical meristem allows for primary growth in the root, which paves the way for lengthening of the plant as well as cell specialization.
The question is incomplete as it does not have the options which are:
- there was no sulfur compound added to the medium, that could be used as an electron donor.
- no oxygen was added to the medium so the organism died.
- there is some inhibitory chemical that is preventing the growth of the bacterium.
- you were using the wrong type of sunlight as the energy source for the bacterium.
Answer:
There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
In the given question, the bacteria which are found in the pond uses light energy to use carbon dioxide and form the glucose molecule. These bacteria are known as phototrophic bacteria.
The process of photosynthesis requires an electron donor and an electron acceptor to use molecule.
The organism when provided the light and carbon dioxide artificially in a culture, the bacteria were not able to grow. The reason for this could be accounted as that there was no electron donor found in the media like sulfur which could donate the electron during the chain reaction.
Thus, the selected option is correct.
From the
books of Geography Seattle is well known for its rain and dark, gloomy skies, but
it may surprise many how pleasant the weather can be, particularly during the
summer months. Using data from meteorological services for the past 50 years,
we can conclude that November through March brings cool temperatures, heavy
cloud cover and rain falling on most days. The coldest month is January with
average lows in the mid to upper 30s F (about 3°C). Weather is pleasant from
April through October, with the best weather in July and August when highs
average in the 70s and rain is uncommon. Skies are mostly clear and smog-free,
though mornings can produce an on-shore flow resulting in low clouds and fog
which typically burns off by mid-day.
