Answer:
As Jane exercises her heart rate and breathing rate increase because he muscles are asking for more oxygen and get rid of more carbon dioxide. More blood is diverted towards the muscles as they need more oxygen for respiration. She needs to burn glucose with oxygen and water to produce energy so she can run. The way she can get this oxygen into her body is through her lungs. Where oxygen from the air diffuses into the blood and carbon dioxide diffuses out.
Cyanobacteria are primitive organisms where chloroplasts are believed to be originated. Now, with the theory of endosymbiosis, this suggests that these organelle from cyanobacteria was engulfed by other organisms which has helped them process light with the help of chloroplasts.
Answer:
G, S, G2, M
Explanation:
Cell cycle refers to the orderly events that prepare the cells for cell division and finally divide the parent cells into the daughter cells. The cell cycle consists of two stages: interphase and M phase.
Interphase is the phase wherein cells prepare to enter the M phase. Interphase has three stages: G1, S, and G2.
G1 is the first gap between represents the time between the end of mitosis and the beginning of the S phase. During the G1 phase, normal growth and metabolism take place. G1 phase is followed by the S phase, the synthesis phase, during which DNA replication and synthesis of histone proteins occur.
The cells then enter the G2 or the second gap during which cells synthesize more proteins and prepare to enter the M phase.
M phase is the phase of nuclear division that divides the nucleus of the parent cell into 2 or 4 daughter nuclei (depending on the type of the cell division that the parent cell has entered).
Therefore, the sequence of the stages that the cell will go through is G, S, G2, and M.
Answer:
<em>When the rod cells become more involved, affected individuals experience a decreased ability to see at night or in low light situations and may lose the ability to see clearly to the sides </em>
The patient does
not respond adequately to fluid replacement and
was given an IV infusion of dopamine hydrochloride at 5 mcg/kg/minute. In addition, to
monitor that the drug is having the desired effect, the nurse should assess the
client for increased cardiac output. <span>At medium doses, which is between 4 – 8 mcg/kg/min, the dopamine
hydrochloride slightly increases the heart rate and improves contractility to
increase cardiac output and recover tissue perfusion.</span>
