what is an acid? What is a base?

Answer:

An acid is a substance that donates hydrogen ions. Now there are more hydrogen ions than hydroxide ins in the solution. This kind of solution is acidc. A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions moves the other way.

Explanation:

Answer:

An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH.

Explanation:

An acid is a substance that donates protons or accepts a pair of valence electrons to form a bond.

A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

If there has been a drought for 6 month's what is the likely response of a seed?​

In the United States, alcoholic beverages that are sold in stores display a government warning stating that pregnant women should not drink alcoholic beverages. This is because
it prevents cleavage division from occurring, so a zygote cannot become a blastocyst.
if a woman drinks alcohol while she is pregnant, she may not be able to ovulate again after childbirth.
studies have proven that alcohol consumption causes long-lasting disorders in the fetus.
the science of chemistry has shown that alcohol is a reactive substance that may interfere with the mother’s food digestion.

Describe the effect of increasing the number of tablets dissolved in water on the number of new leaves in four weeks. 25 points

Plants may grow faster if they have more
carbon dioxide.
Clear plastic bag
Indigestion tablets dissolve in water to form a
solution.
This solution slowly gives off carbon dioxide.
A student set up an investigation to see what
concentration of carbon dioxide is best for
increasing the growth of geranium plants.
Dish containing water
and one tablet
The student:
put a geranium plant in a clear plastic bag
put a dish containing water and one tablet in the bag and sealed the top of the bag.
The student:
set up 5 more experiments each with water and a different number of tablet and left all
the plants in a well-lit place for four weeks.
The student used a clear plastic bag, not a black plastic bag.
Explain why.

how do organisms generate energy when oxygen is ot available​

In Hawaii, new land forms when lava erupts from Kīlauea volcano and hardens. The new land is without any living things. The first organisms to populate the surface of that new land are known as species. With time, a series of changes called succession occur on the new land through which it becomes colonized by a variety of organisms.
