Answer:
cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.
Explanation:
THE ANSWER IS FERMENTATION!!!!
Answer:
If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.

brief explain the roles of the following in photosynthesis 1 NADP 2) Ribubose diphostate 3) photosytem 1 ad 2
Answer:
1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.
3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II
● PhotosystemSII acts first during the light transformation process in photosynthesis.
● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from
plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.

During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?
Explanation:
Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.
Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.
The overall equation for this pathway is:
1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O
Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.
Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.
What does glycolysis process?Glycolysis is the method of breaking down glucose. Glycolysis can take place with or without oxygen. Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water.
Glycolysis occurs in the cytoplasm.
Thus, Glycolysis is the method of breaking down glucose. Glycolysis occurs in the cytoplasm.

what was the speed of a car that traveled 240 m in 12 s
Answer:20
Explanation: Because when you divied 240 by 12 you get 20.
240/12=20
Answer:
20m/s
Explanation:
Speed is equal to distance/time. Since we know that the distance is 240m and the time taken to travel 240m was 12 seconds, we can divide them 240/12 and once we do this we can get our final answer of 20m/s.

the structure labeled A in the figure below is called the
Answer:
Centromere
Explanation:
Connects sister chromatids
The structure labelled A in the figure is a centromere.
What is a centromere?The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.
The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.
Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted
The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

Explanation:
prostate cells usually require testosterone and other androgens to survive. but some prostate cancer cells thrive despite treatments that eliminate androgens. one hypothesis is that estrogen, often considered a female, may be activating genes normally controlled by an androgen in these cancer cells. desribe one or more experiments to test this hypothesis
One can check for the translation and transcription of genes of interest in the absence of androgens, one can check whether the estrogen is involved in the expression of oncogenic proteins of interest by depleting the estrogen, and one can also examine the existence of estrogen receptor complex in the prostrate cancer cells nuclei.
• One can check for the translation and transcription of genes of interest in the non-existence of androgens and if these genes are expressed then this suggests that apart from androgens other factors also affect their expression.
• One can deplete the estrogen from cancer cells and if the involvement of estrogen is there in the expression of oncogenic proteins of interest then its reduction will result in diminished multiplication rates in cancer cells.
• One can also test the existence of estrogen-receptor complex in the prostate cancer cells nuclei to confirm that estrogen is taking part in the regulation of gene expression.
Thus, various experiments can be conducted to check that whether the expression of genes controlled by the androgens under normal conditions are affected by the presence of estrogens in prostate cancer cells.

Inversion of DNA sequences within chromosomes is a common process in evolution. The following gene arrangements in a particular chromosome are found in four different species: First sequence: STUVWX Second sequence: UVXTSW Third sequence: UVWSTX Fourth sequence: SWVUTX Assuming that the arrangement in the first sequence is the ancestor/reference arrangement, in what evolutionary order did the four species arise, such that the fewest number of inversions occur between each species (place the first sequence as the earliest species in your ordering)2341
Answer:
The correct answer is - 1, 4, 3, 2.
Explanation:
It is given that the first sequence represents the earliest or ancestor species therefore, the first sequence would be - STUVWX
After the inversion, the highlighted sequence of the first sequence STUVWX gives rise to the second sequence as:
STUVWX
SWVUTX
Thus the second sequence after Ist inversion would be SWVUTX
2nd inversion, Third sequence:
SWVUTX
UVWSTX
Thus the third sequence after 2nd inversion is UVWSTX
3rd inversion, fourth sequence:
UVWSTX
UVXTSW
Thus, the fourth sequence after 3rd inversion is UVXTSW

Antibiotics can be used to kill the specific pathogenic bacterium, Mycobacterium tuberculosis, that causes tuberculosis. The appearance of antibiotic-resistant strains has made it more difficult to cure M. tuberculosis infections. These antibiotic-resistant bacteria survive and pass on the genes to their offspring, making the resistant phenotype more common in the population. DNA analysis indicates that the genes for antibiotic resistance are not normally present in bacterial chromosomal DNA. Which of the following statements best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA?
a. The antibiotic-resistant bacteria release a hormone that signals neighboring bacteria to become resistant.
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
c. The antibiotic-resistant bacteria are the result of bacteria that specifically modify their own chromosomal DNA to neutralize the antibiotics
d. The antibiotic alters the bacterial genome of each bacterium, which results in an antibiotic-resistant population.
Answer:
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
Explanation:
Transformation is a genetic process by which bacteria take up foreign genetic material from the surrounding environment. In consequence, this process does not involve direct cell-to-cell interaction. Transformation allows the occurrence of horizontal gene transfer (HGT) events among different bacteria capable of exchanging extrachromosomal DNA plasmids, thus increasing genetic diversity in bacteria. Many different types of bacteria can acquire foreign genes, including antibiotic resistance genes, by HGT events involving plasmids, transposable elements, bacteriophages, etc.

It helps in determining the occurrence and existence of particular kind of species on planet earth. It can also be used to trace the development and passage of a particular kind of trait from one generation to the another. It can also be used to trace back various geological events that occurred on planet earth like volcanic eruption, plate tectonics, and others. The geologists used it for tracing the geological activities that occurred in the history of earth. Archaeologist study about rocks and fossils to trace back the geological time scale. Paleontologist study the existence of a particular species via studying the fossil evidences and reconstructing the primitive conditions by developing a geological time scale. They trace the evolutionary history of organisms.
