Answer:
Photosynthetic cotyledons remain on the plant until the first true leaves appear and can begin to perform photosynthesis. This is generally just a few days and then the seed leaves fall off. They remain to help direct the energy stored in the seed to new growth, but once the plant is self-sufficient, they are no longer needed.

Ans: D
Chemical changes:-
occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

I think its C. but i could be wrong. I hope this helps u
Explanation:
A reasonable conclusion supported by these observations is that the animal was endothermic and had a high metabolic rate.
<u>Explanation:</u>
With reference to warm-blooded species is preferred the endothermic are the species that preserve a steady body temperature regardless of the ambient temperature. Endothermic species mainly include animal kingdom birds and mammals. Many shrimp, however are endothermic too.
If a variation occurs, i.e. if the heat produced is less than the heat loss, the metabolic rate increases to compensate for that loss. Shivering is another method used by people and many other warm-blooded organisms to boost their body temperature. But in case the heat loss is smaller than the heat produced, the process of panting or suddening occurs to increase the heat loss.
