Photosynthesis is the process.
The answer is ‘in the dermal papillae of hairless skin’. Dermal papillae is the layer of the skin (upper dermis) with numerous blood vessels and nerves that serve the epidermis of the skin. Tactile corpuscles (nerves) are mostly found in this region and occur mostly in hairless thick skin such as in finger and toe tips.
Answer:
The correct answer will be option-A
Explanation:
A scientific experiment is designed in a way that it tests the predicted hypothesis and so contains the three different types of variables namely: independent (can be modified), dependent (to be studied) and the control (kept constant and unchanged).
In the given question, since the scientists studied the effect of nitrate and phosphate in which he provided the plant samples with nitrate and phosphate but he missed the control sample which should lack the variable to be tested that is nitrate and phosphate. This control variable helps the scientist to study the relationship between other samples.
Thus, option-A is the correct answer.
Answer:
1.- The protein RDA is 0.8 g/Kg of body.
Explanation:
1.- This is a standard value.
2.- If a pound = 0.45 kg
so 141 pounds = x
x= 141 pounds x 0.45 kg = 63.45 Kg
If the healthy body needs 0.8 g protein = 1 kg body
x = 63.45 kg
x= 63.45 kg x 0.8 = 50.76 g of protein every day.
3.- If 1 g protein = 4 Kcal
50.76 g = x
x= 50.76 g protein x 4 cal = 203.04 cal
If her diet is based in a 1200 cal so...
(203.04 cal / 1200 cal) x 100 % = 16.92 % of her total energy intake
