Answer:
sprint runners rely on lactic acid fermentation as there main source of energy,printing takes a lot of effort and a lot of big movements and a lot energy on demand . cellular respiration makes ATP at a slower rate than lactic fermentation therefore it is anaerobic
Explanation:
the sprinter uses ATP already in muscles as well as ATP produced by lactic acid fermentation. A long-distance runner gets its ATP solely off of cellular respiration
hope this helps
Answer:
The development by scientists of a new color in a rose is the result of genetic modification
Explanation:
The development of new colors in the species of roses is given by the genetic modification by means of the introduction of genes of other species that express other colors absent naturally in the roses. The genes that are inserted are those that encode pigmentation for a certain color.
In a hen house, the length of daylight is prolonged by using indoor lighting. the stimulus for egg laying is
(a) food
(b) warmth
(c) light
(d) amount of water.
The correct answer is option (c) light.
Light is found to have a significant effect on egg laying by hens in the hen houses or poultry. Photoperiod is the length of the time within a day to which the hens are exposed to sunlight or artificial source of light. Egg production is reduced if the light intensity and duration is reduced. A peak production of hens is observed with the photoperiod is lengthened or a longer photoperiod.
Natural day light exposure to hens results in the production of not more than 40 eggs. Whereas, a prolonged day light of 12- 14 hours by indoor lighting increases the number of eggs layed to around 60 eggs. Thus, the stimulus for egg laying is the light.
Thus, In a hen house, if the length of daylight is prolonged by using indoor lighting, the stimulus for egg laying is light.
