Materials Computer 25 non-germinating peas

Vernier computer interface 250 mL respiration chamber

Logger Pro Thermometer

Vernier CO2 gas sensor Two 100 mL beakers

Bio Chamber 250 Paper towels

25 germinating peas

Procedures

1. Connect the gas sensor to the computer interface.

2. Obtain 25 germinating peas and blot them dry between two pieces of paper towel.

3. Place the germinating peas into the germination chamber.

4. Place the CO2 sensor in the respiration chamber as shown in figure 1

5. Wait 4 minutes, then begin collecting data. Record the CO2 concentration readings every minute for 10 minutes.

6. Fill the respiration chamber with water and then empty it. Thoroughly dry the inside of the respiration chamber with a paper towel.

7. Obtain 25 non-geminating peas and place them in the chamber. Repeat steps 3 – 7.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
