Human can produce a maximum mechanical power of 1/3 hp (horse-power).
Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)
So:
1 ph = 746 watt = 746 J/s
1/3 ph = 248.6 J/s
we're looking for the calories, so
1 joule = 0.239006 calories
So human produce a maximum mechanical power of:
248.6 J/s = 82.88 calories per second.
We're looking for the number of calories consumed in three hours, so:
82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).
The number of food calories is 895.2 food calories
Answer:
Transcriptional regulators function to regulate the expression of different genes and also to affect the expression of other transcriptional regulators, thereby the combination of a few transcriptional regulators is sufficient to modulate gene expression patterns
Explanation:
Transcriptional regulators are able to control gene expression by binding to cis-regulatory elements on the genome. For example, in plants, MADS-box proteins are transcriptional regulators that contain an evolutionary conserved DNA-binding domain (i.e., MADS-box domain) which regulate simultaneously the expression of many different genes by binding to a conserved DNA motif called CArG box [CC(A/T)6GG] located in the promoter region of many genes expressed at specific stages of plant development. Within the cell, transcription regulators function not only by controlling the expression of different genes but also by affecting each other's activity, thereby creating different combinations where the expression of a limited number of transcription regulators is sufficient enough to regulate gene expression patterns.
Answer:
The overies release progesterone and estrogen
Theres three major estrogens estradiol, estrone, and estriol, those work together to help develop female characteristics during puberty to ensure fertily.
Answer: Reduction of the greenhouse gas carbon dioxide in the atmosphere
Explanation:
phytoplankton use photosynthesis to take the sun’s light waves and convert it into energy. They also take carbon dioxide and convert it into oxygen for other organisms to breathe.
