The question lacks the multiple options. The options are as follows:
A. After 1 hour of moderate-intensity exercise (60% to 85% VO2 max), when blood glucose levels dwindle
B. After 1 to 3 hours of continuous moderate-intensity exercise (60% to 85% VO2 max), when glycogen becomes depleted
C. After 5 to 6 hours of continuous low-intensity (50% to 60% VO2 max), when blood glucose levels dwindle
D. After 30 minutes of continuous high-intensity (70% to 90% VO2 max), when glycogen becomes depleted
Answer:
Option (B).
Explanation:
Glucose is the monosaccharide and the single momoneric unit and when repeated again and again can leads to the formation of polymer. The glucose acts as the primary source of the energy.
The glucose is breakdown to form the ATP. The glucose is continuously used in the exercises. If the glucose is not taken, the individual be only able to perform the moderate exercise only for 1-3 hours. The individual feels fatigue and needs rest if glucose consumption is decreases in the body.
Thus, the correct answer is option (B).
The answer is B. circulatory, respiratory, and nervous systems
Although all systems in the body are interrelated and impact one another, the systems that have the most important roles in regulating blood pressure are the ones in B. The circulatory, obviously, is the most important because it consists of the heart, blood vessels, and blood. When the heart pumps blood, it creates pressure on your arteries. These processes are communicated throughout your body using the brain or nervous system. The respiratory system also works closely with the circulatory system because when oxygen enters the blood, it travels to the heart and is pumped to the rest of the body.
Answer:
6. Prophase 1
7. Interphase
8. Metaphase 2
9. Prophase 2
10. Anaphase 1
11. Anaphase 2
12. Telophase 1
13. Metaphase 1
14. Telophase 2
Explanation:
Following is a summary of the events of meiosis:
Interphase:
Prepares the cell for division. Duplication of DNA, duplication of centrioles occurs and the cell grows in size. At this stage the cell is diploid (2n).
Prophase 1:
First stage of Meiosis 1.The centrioles move to the poles of the cell, the nuclear membrane disintegrates, homologous chromosomes pair up (in the form of tetrad), form a chiasmata and then exchange segments of chromosomes with each other. This process is called crossing over.
Metaphase 1:
Involves the arrangement of the crossed over, homologous chromosomes on the metaphase plate which is sort of like a web of spindle fibers that originates from the centrioles.
Anaphase 1:
The tetrads arranged on the metaphase plate are pulled apart by the spindle fibers. This is the result of tension that build up in the spindle fibers as they grow towards opposite poles.
Telophase 1:
The last stage of meiosis 1. Involves the arrival of the chromosomes at the poles, the nuclear membrane starts to form and the chromosomes start decondensing. Telophase 1 yields 2 daughter cells with half the number of chromosomes as that in the parent cell.
Meiosis 2:
Meiosis 2 is exactly similar to mitosis. The only difference is that the haploid cells entering meiosis 2 do not duplicate their DNA. Meiosis 2 just involves the separation of the sister chromatids of homologous chromosomes.
- As mentioned above, interphase does not occur before meiosis 2.
- Prophase 2 involves the disintegration of nuclear envelope, centrosomes start moving to the poles.
- Metaphase 2 arranges the chromosomes on metaphase plate.
- Anaphase 2 separates the sister chromatids from the chromosomes.
- Telophase 2 develops the nuclear envelope and separates the nuclei of the daughter cells into 2. Nuclear division id followed by cytokinesis (division of cytoplasm). Telophase 2 result sin 4 haploid daughter cells with one chromatid from each chromosome.
