Explanation:
The structure of the leaf is adapted for gas exchange. The cells in the spongy mesophyll (lower layer) are loosely packed, and covered by a thin film of water. There are tiny pores, called stomata , in the surface of the leaf. Most of these are in the lower epidermis, away from the brightest sunlight.
The stomata control gas exchange in the leaf. Each stoma can be open or closed, depending on how turgid its guard cells are.
In the light, the guard cells absorb water by osmosis, become turgid and the stoma opens.
In the dark, the guard cells lose water, become flaccid and the stoma closes.
Diffusion of carbon dioxide, oxygen and water vapour into (or out of) the leaf is greatest when the stomata are open.
B. they make ATP from glucose molecules and use when necessary
Sedimentary rocks are 'built up' over time, and if something dies overtime, lets say an animal, it will get buried and minerals will fill it and it becomes a fossil. fossils are important because they tell us about the past and what is was like way back when.
A true Coelom develops completely within the mesoderm. It is also referred to as a body cavity passing down the trunk of some organisms <u>which originates through the splitting of the mesoderm during the initial stages of embryonic and later fits inner to it</u>. Organisms that have a Coelom contain complex structures and are found higher in the taxonomic order. i.e. the Coelomates
Answer:
15
Explanation:
Since the law of conservation of mass applies to all the chemical reactions this will also end in 10+5 equalling 15 grams
