Answer:
from the sun
Explanation:
producers get light energy from the sun
Answer:
The central dogma of molecular biology best describes the relationship between proteins and nucleic acid.
Explanation:
Nucleic acid such as DNA is the repository of genetic information in most organism.
The genetic information stored in DNA is Transferred to RNA by transcription which deals with the the production of mRNA from DNA.
The mRNA then undergo translation to transfer its own own genetic information in form of codons to specify amino acids of a protein molecule.
Thus the Central dogma of molecular biology relates proteins and nucleic acids.
I believe the term for an observable trait of an organism would be called or noted as the organism's phenotype.
Answer:
B- Photosynthesis
Explanation:
Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.
Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.
Photosynthesis occurs in two stages:
- The light reaction stage
- The dark reaction stage
The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.
In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.
Answer: D. Epinephrine
Explanation:
During perceived danger the fight-or-flight response includes faster heart beat, quickened breath, tense muscles and thought speed up. This co-ordinated set if physiological changes is triggered by two hormones of the adrenal gland, epinephrine and norepinephrine.
The major activities of these hormones is to increase the amount of chemical energy available for immediate use, increase the heart rate and stroke volume and dilate the bronchioles in the lungs, action the raise the rate of oxygen delivery to the cell.
Answer is epinephrine
