<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.

The correct answers are as follows:
1. During cytokinesis, THE CELL MEMBRANE PINCHES IN TO FORM TWO NEW CELLS.
Cytokinesis is the physical process of cell division, it divides the cytoplasmic content of the parental cell into two new daughter cells. Cytokinesis takes place in both mitosis and meosis.
2. The correct order of the phases of mitosis are as follows: PROPHASE, METAPHASE, ANAPHASE AND TELOPHASE.
Mitosis is the process of cell division by which a cell is divided into two new cells. The process occurs in four basic stages and result in the formation of two new cells.
3. The following terms are related to sexual reproduction: MATING SYSTEM, GAMETE FORMATION AND AMPLEXUS.
Amplexus refers to the mating positions of frogs and toads during sexual reproduction. Mating system refers to the number of mating partners that an animal has during the mating period. Gamete formation is the process by which sex cells are made and it occurs in both male and female animals.
4. As a cell is preparing to divide by mitosis, the DNA MUST BE COPIED.
When a cell is getting ready to divide by mitosis, it will undergo a stage called interphase, during which the cell prepare for cell division. During interphase, the cell undergo some process and these include the copying of the DNA. The cell copies its DNA so that it has two copies of each strand.
