Answer:
Obese
Explanation:
Obesity can occur at any age but in recent times more and more children are becoming obese. They develop an unhealthy relationship with food from a young age. Food rather than being a source of nutrition becomes just a source of sensory stimulation.
These children often chew very fast and swallow food without properly breaking it down. Thus they are not able to realize when they are full. They ignore the internal cues for hunger or fullness and keep eating to satisfy their palate. As a result, they become obese.
Answer:d.are eventually replaced by electrons from photosytem 11
Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen
Answer:
All colour except which is already present in the body.
Explanation:
The plant leaf has green colour so the plant absorb all the colour except green. The presence of green colour causes reflection of green colour so that's why we can see the green colour of the leaves. Every material or substance have a specific colour which can be seen when they absorb all light except the colour which is already present in it so we can say that that colour is not absorbed by the body which is already present in it.
