How is glucose broken down in cellular respiration?
Answer: Glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria.
Explanation:
Glucose is broken down in cellular respiration into carbon dioxide and water.
What is cellular respiration?Cellular respiration is a series of metabolic processes that take place inside cells to transform biochemical energy from meals into a substance known as adenosine triphosphate (ATP).
A glucose molecule gradually decomposes into carbon dioxide and water during cellular respiration. In the process of transforming glucose, some ATP is directly created. But far more ATP is later created through a procedure known as oxidative phosphorylation.
Glycolysis is the process by which glucose is metabolized in the cytoplasm of the cell. The pyruvate molecules are delivered to the mitochondria in stage two.
Therefore, during cellular respiration, glucose is converted to carbon dioxide and water.

Answer:False
Explanation:All viruses do not cause diseases,instead some are very beneficial,the help to prevent infections from the plague bacteria.But some viruses cause infectious diseases like HIV/AIDS,Ebola,Corona e.t.c and viruses are not called parasites because parasites are different from bacteria or viruses because their cells share many features with human cells and some parasites only replicate within a host organism but some multiply freely in the environment.
Which is part of the theory of evolution by natural selection?
A. All animals in a population are able to reproduce.
B. Animals have no variation among themselves.
C. Adaptations cannot be passed along to later generations.
D. Small changes add up over many generations.
Answer:
D. Small changes add up over many generations.
Explanation:
It's not A because not all animals in a population can always reproduce. Some may be infertile.
It's not B because genetic variety is something that occurs naturally. Because of genetic variety, random mutations can occur (these mutations later become adaptations).
It's not C because adaptations can be passed down to later generations. These adaptations can lead to natural selection which eventually leads to evolution.

from the atmosphere to
The atmospheric temperature decreases when snow starts melting because the snow
melt
Answer:
The atmospheric temperature decreases when snow starts melting because the snow absorbs thermal energy from the atmosphere to melt.
Explanation:
The temperature of the air, the intensity of the sun, the speed of the wind, and the amount of humidity are the factors that influence the melting of the snow. The thermal energy in the atmosphere is absorbed by the snow because the temperature of snow is less than the temperature of the atmosphere. When the flow of temperature takes place, the energy also flows. The thermal energy helps the snow to melt because the snow requires warmth to melt.

When Engelmann exposed photosynthetic algae to light in the presence of aerobic bacteria, he found that some wavelengths of light produced a higher rate of photosynthesis, as evidenced by the number of bacteria gathered near the algae. Based on his results, what color of light did Engelmann find associated with the highest rate of photosynthesis?
A. Red and blue
B. Yellow and green
C. Yellow
D. Red
Answer:
A. Red and blue
Explanation:
Theodor Wilhelm Engelmann, born in 1843 and died in 1909, was a German scientist. He was the scientist who detected which wavelengths of light produced the best photosynthetic activity in green alga. In his experiment, Engelmann exposed the photosynthetic algae to different wavelengths in the light spectrum. He then added aerobic (oxygen-dependent) algae to see where they will accumulate the most in order to detect the best wavelength for algae photosynthesis.
He discovered that the aerobic bacteria accumulated in the parts of the algae exposed to red and blue wavelength of light. This is because the algae exposed to the red and blue light produced more oxygen due to increased photosynthetic rate. This attracted the aerobic bacteria, which needs oxygen, to that particular area with that wavelength.
If carbon in the atmosphere increase will carbon on earth increase too?
Answer:
When carbon dioxide concentrations rise, air temperatures go up
When carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.
A scientist has sequenced a gene from a multicellular eukaryotic organism. Brendan claims that by analyzing the gene sequence and applying
the genetic code, he can conclude the sequence of amino acids in the protein that forms after the gene is transcribed and translated
Which statement provides the strongest evidence against the validity of Brendan's claim?
A. Regulatory proteins may activate or deactivate a gene, often by very complex mechanisms.
B. During transcription, a strand of mRNA is synthesized from complementary base pairs, with the substitution of uracil (U) for thymine
(T)
C. During translation, anticodons on tRNA bind to codons on mRNA as part of the process that forms the polypeptide.
D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.
Answer:
D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.
Explanation:
According to this question, a gene was sequenced by scientists from an eukaryotic organism. Brendan claims he can conclude the resulting protein after the transcription and trans of the gene.
It is true that transcription and translation are the processes that a gene undergo in order to be expressed i.e. produce protein. However, a gene sequence contains both the coding and non-coding regions in it. The coding regions code for a protein and are called EXONS in the mRNA while the non-coding regions do not encode proteins and are called INTRONS in the mRNA.
These introns are removed from the mRNA molecule that results from the transcription of a gene. The mRNA undergoes a process called SPLICING, which removes the non-coding part of the mRNA (introns) and joins the coding parts (exons).
Hence, if this occurs, Brendan will not be able to accurately conclude the resulting protein from that gene sequence because a portion of that gene will still be removed during SPLICING of post-transcriptional processing.

Organisms may contain up to five levels of organization within their bodies. Which level of organization is best represented by
the liver?
Answer:
ORGAN
Explanation:
The liver is a very important organ in the system of multicellular organisms e.g humans. It performs various functions in the body e.g. detoxification, metabolism etc. As rightly said in this question, multicellular organisms are made up of five levels of organization.
Firstly, all living organisms are made up of CELLS, which are the basic unit of life. Cells come together to form the TISSUE. Tissues that perform similar functions come together to form the ORGAN, the organ that specifically play a similar role in the body are collectively called ORGAN SYSTEM. The various organ systems make up the whole ORGANISM.
In this five level of organization, the liver falls under the ORGAN category because it is made up of cells called Hepatocytes, which come together to form tissues. The tissues collectively make up the LIVER.

Based on the information in the graph, explain what physical process causes the cell to change size.
Answer:
Osmosis
Explanation:
Osmosis is the process in which solvent molecules move from lower to higher concentration through a semipermeable membrane.
When a cell is placed in a hypertonic solution, the cell loses water and moves from higher concentration to lower concentration that is from inside the cell to the water solution and causes shrinking of cell.
Shrinking of cell means decrease in size of the cell along with the passing time and cell loses all its water.
Hence, the correct answer is osmosis.
