<span>Calcium<span> is the element responsible for most of the material found in teeth.
Calcium plays a vital role in the formation and maintenance of healthy teeth and gums. Calcium makes the jawbones healthy and strong in order to hold the teeth in place.
Dairy foods such as cheese and yogurt, beans, cabbage and brown rice are good sources of calcium.</span></span>
Answer:
Spore
Explanation:
Most of the fungal species reproduce through spores. Spores are the reproductive structures of fungi that help in the survival of fungal species under unfavorable conditions and their dispersal to new habitats. Fungal spores are very light in weight and are dispersed with wind currents.
For example, ascospores are the sexual spores produced by fungal species of the group ascomycetes and are carried with the wind.
B because when the positive feedback happens it increases the temperature and when the negative feedback occurs the temperature lowers itself
Light excites the electron in the electron transport train and once it goes down the train water replaces the missing electron. the electron transport chain brings it down, hydrogen gets pumped across then when it slides back down the other side, energy is created. chlorophyll is the goo stuff that lets it absorb the light. carbon dioxide goes into the calvin cycle and it rearranged uses energy from the first part. the products of this part is sugar (C6H12O6) and oxygen.
water and carbon dioxide go in, oxygen and sugar come out
Answer:
This statement is false.
Explanation:
Ionic bonds have relatively high melting and boiling points, compared to that of covalent bonds.
Ionic compounds have strong electrostatic bonds between oppositely charged ions. Covalent bonds, on the other hand, have weaker attractions between molecules.
Remember, the melting point, is simply the amount of heat (energy) it takes to break apart the molecular bonds. The stronger the bonds, the harder it will be to separate them!
Hope this helps! :)
