Answer:
The correct answer will be option-A.
Explanation:
Photosynthesis is a process which uses sunlight energy to synthesize food in the form of glucose. The process takes place in the chloroplast in two stages: light-dependent reactions and light-independent reactions.
The light-independent reaction produces to convert the carbon dioxide from the atmosphere to glucose through the Calvin cycle. The carbon gets fixed and reduced form+4 state to +1 state.
Respiration is the process which oxidizes the glucose molecule to produce energy in the form of ATP molecules. This ATP is utilized by the cell to perform various functions.
Thus, option-A is the correct answer.
Answer:
its either telophase or metaphase. i think its closer to telophase though since it has the cleavage furrow.
Explanation:
<span>prophase I. the chromosomes condense, and the nuclear envelope breaks down. ...Metaphase I. pairs of homologous chromosomes move to the equator of the cell.Anaphase I. homologous chromosomes move to opposite poles of the cell.Telophase I and Cytokinesis. ...Prophase II. ...Metaphase II. ...Anaphase II. ...<span>Telophase II and Cytokinesis.</span></span>
<h2>Cannon -Bard theory</h2>
Explanation:
- Alone in the woods, Pedro hears a noise. He thinks he sees a bear coming toward him. His heart starts pounding and then, a moment later, he realizes how frightened he is. This sequence of events is BEST explained by the <u>Cannon-Bard t</u>heory of emotion.
According to Cannon-Bard theory, all the emotional expressions occur due to the stimulation of hypothalamic structures present in brain. This theory also states that feeling and physiological effects of an emotional stimuli occurs simultaneously.
Here, James thinks that a bear is coming, this is a stimulus. His heart starts pounding that is the physiological effect of the stimulus and the next moment he feels frightened which is a feeling.
So we conclude that in this case, the physiological effect and feeling of emotion occurred simultaneously. So these sequence of events is best explained by Cannon-Bard's theory.
DNA is the molecule, which is the source of information for transcription.
• During the process of transcription, RNA polymerase is an enzyme, which is accountable for copying a sequence of DNA into a sequence of RNA.
• The RNA polymerase monitors the phenomenon of transcription.
• At the time of transcription, the information is stored within a molecule of DNA, which is further copied into a new molecule of messenger RNA.
Thus, the correct answer is DNA.
