The balance between the discharge and recharge for a groundwater supply is called the
A) restoration
B) cation exchange capacity
C) ecological footprint
D) water budget
E) Fujita scale
Answer:
Water budget? I thought Water Table would have been one of the answers because I’m taking the test right now
Explanation:
In hydrology, a water balance equation can be used to describe the flow of water in and out of a system. A system can be one of several hydrological domains, such as a column of soil or a drainage basin. Water balance can also refer to the ways in which an organism maintains water in dry or hot conditions.

Answer:
Oxygen.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
Oxygen is the final electron acceptor in the electron transport chain of cellular respiration. The oxygen accepts electron when it passes through ATPase and the electron transport chain of cellular respiration.
Answer:
oxygen

Can a nucleus with three chromosomes successfully
divide by mitosis?
Please help me with this!!
Answer:
I am sure they can
Explanation:
Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.

If an organism cells all contain the same DNA why does one cell become bone while another cell becomes lung tissue
Answer:
very interesting question. it all has to do with DNA, which is a long strand of molecules. basically, only certain parts of the DNA, called genes, are used to in every cells. for instance, a bone cell will only use genes that allow it to build or break down bone

An mRNA that is readily transported into cytoplasm should have all of the following
EXCEPT
a. exons
b. a poly-A tail
c. a 5’-cap
d. introns
Explanation:
In eukaryotic cells, pre-mRNA has to undergo 3 stages of RNA processing before being transported into the cytosol. Specifically during RNA Splicing, small nuclear RNAs (snRNAs), small nuclear ribonucleoproteins (snRNPs) and other proteins form a spliceosome which excises introns and splice together exons. Introns are considered junk material and does not stay with the mRNA.
The answer is Introns. (D)
Answer:
d. introns

Nerve impulses are carried to another part of the body by a neuron’s:
(1) dendrites
(2) axon
(3) synapse
(4) neurotransmitter
Answer:
1.
Explanation:
Dendrites is the neuron's that receives nerve impulses and carry it to another part of the body.
Nerve impulses are the messages that are transferred from one part of the body to the another. These messages are carried across the body with the help of neuron's named dendrites.
Dendrites are branched like projections of in the nerve cell. Through these projections, message passes across the body.
Therefore, option 1 is correct.

Explain the changes that occur as a tadpole becomes an adult frog or toad.
Answer:
Well one of the first changes it the tadpoles start growing legs. Then it will continue to grow, changing and changing as it goes. Then it will start to live on land, and it will live on land as a tiny frog until it is completely grown up.
Answer:
Tadpoles have fins, gills, and a two-chambered heart, similar to fish. As tadpoles grow up, they develop legs, lungs, and a three-chambered heart. The tail is reduced in size and lost completely as they prepare to leave the water.

What events in sexual reproduction contribute to genetic variation in a population that contributed to evolution
of the species on our planet? Explain.
Answer:
Meiosis is the first step in sexual reproduction during which crossing over and recombination develops new combinations of genes on chromosomes. When gametes are produced they under go random fertilization and offsprings with great genetic variations are produced.
This leads to evolution of species on the planet.

describe in detail Alfred Wegener's idea of continental drift
HELPP
Answer:
Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

Why does soil lose its fertility from time to time?
Answer:
The soil losses its fertility when we grow many crops again and again on it as the consume all the nutrients present there. it can be restored by growing legumes in the soil or leave it barren for some months
Soil loses its fertility or when topsoil is lost due to erosion. ... The cotton took all the nutrients from the soil, and the nutrients were not replaced. Loss of Topsoil: Wherever soil is exposed, wind and water can erode it. Plants can cover and protect the soil in many ways.
