Answer:

In the nitrogen fixation process, nitrogen fixing bacteria converts the N2 in the atmosphere into NH3 (ammonia). This bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil. ... From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification

*The key function of each of the two photosystems is to absorb light and convert the energy of the absorbed light into redox energy, which drives electron transport.

In PS II (the first photosystem in the sequence), P680 is oxidized (which in turn oxidizes water), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).

In PS I, the PS I primary electron acceptor is reduced (which in turn reduces other compounds that ultimately reduce NADP+ to NADPH), and P700 is oxidized (which in turn oxidizes the electron transport chain between the photosystems).

How is it that a code consisting of only four letters as in dna can specify all the different parts of an organism and account f

LekaFEV [45]

The genetic code can be defined as a set of rules used to encode information from genetic material (DNA or RNA ) into proteins. There are sequences of nucleotide triplets, -codons which specify which amino acid will be added next during translation (protein synthesis). Genetic code consists of 64 codons and this means that some amino acids are specified by more than one codon.

Genetic code has a role to determine amino acid sequence of protein (primary structure of protein). Location and the function of all those synthesized proteins is determinated by regulatory genomic regions (gene regulatory codes).

Proteins perform a wide range of functions within organisms such as catalysing metabolic reactions, DNA replication, stimuli response, structure role, transport role. So, all the diversity of organisms on this planet is due to protein variety.

vitfil [10]

Answer:

The correct answer is -

Decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

NO effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

Increase plant growth - increase CO2, increase sunlight, increase H2O

Explanation:

Decrease in exposure of sunlight to the plant or less intense light will affect the production of oxygen and glucose negatively which affect the growth of the plant. Decrease CO2 will be affect the growth of the plant similarly as light and water molecules which is decreased in plant growth.

Increase in the in production of the products which are 02, glucose, will have no effect in plant growth though increase in the carbon dioxide, water, and sunlight will positively affect plant growth.

Thus, the correct answer is - decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

no effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

increase plant growth - increase CO2, increase sunlight, increase H2O

1. Cell starts into mitosis phase of the cell cycle.

2. Helicase begins to break the hydrogen bonds between the nitrogen bases. (The double helix has to be unwound in order to expose the nucleotides)

3. DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. (this allows a new DNA strand to be made on the existing one)

4. Free floating nucleotides pair up with exposed nitrogen bases (this is what really builds the new strand, based around the template strand)

5. Two new molecules of DNA are created

Statements:

Adenine

Cytosine (Car in the Garage, Apple in a Tree is a good trick to know how they pair)

DNA

Replication
