Which is the final electron acceptor in the electron transport chain of cellular respiration?
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.

oxygen

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.

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.

Genetics: A geneticist is studying two genes. Each gene can be either dominant or recessive. A sample of individuals is categorized as follows. Write your answer as a fraction or a decimal, rounded to four decimal places. Gene Dominant Recessive Gene Dominant Recessive (a) What is the probability that in a randomly sampled individual, gene is recessive
Complete question:
A geneticist is studying two genes. each gene can be either dominant or recessive. a sample of 100 individuals is categorized as follows.
gene 2
dominant recessive
gene 1
dominant 56 24
recessive 14 6
(a) what is the probability that a random sampled individual, gene 1 is dominant
(b) what is the probability that a random sampled individual, gene 2 is dominant
(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant
Answer:
(a) what is the probability that a randomly sampled individual, gene 1 is dominant ---> 80%
(b) what is the probability that a randomly sampled individual, gene 2 is dominant ----> 70%
(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant ----> 70%

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.

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.

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
