Answer:
Glycolysis is the first step of the cellular respiration in an organism which is metabolic pathway that is completed in the cytosol of the cell that leads to the converting glucose to the pyruvate in order to produce energy in form of ATP:
1. Glucose-6-phosphate is ---> fructose-6-phosphate
2. fructose-6-phosphate ---> fructose-1,6-biphosphate
3. fructose-1,6-biphosphate ---> glyceraldehyde-3-phosphate(GAP) and dihydroxyacetone phosphate (DHAP).
4. GAP is oxidised ----> 3-bisphosphoglycerate + NADH
5. 3-bisphosphoglycerate ----> 1,3-bisphophoglycerat
6. 1,3-bisphophoglycerate ----> 3-phosphoglycerate
7. 3-phosphoglycerate ----> 2-phosphoglycerate
8. 2-phosphoglycerate ----> phosphoenolpyruvate (PEP)
9. phosphoenolpyruvate to ADP ----> pyruvic acid + ATP
Formation of ATP occurs in both pathways or process that are respiration and fermentation. Fermentation is a catabolic pathway leads to the degradation of sugars (partial) that result in the gain of energy and this energy are absorbed in ATP. There are difference of the amount of energy or ATP produce in these process in respiration 38 ATP are produced whereas during fermentation only 2 ATP are produced.

can a impact in one species over time can impact an ecosytem ?
Answer:
Yes
Explanation:
Yes, the impact on one species over time can impact ecosystem.
An ecosystem is consist of biotic and abiotic organisms. There is a major relationship between biotic and abiotic or biotic and biotic components.
The relationship between biotic and biotic components is called food chain, in which one organisms depends on others for their survival and balance the energy flow in the ecosystem. So impact on any one species in the food chain will impact the whole ecosystem.
For example: Plants are the producers in the food chain, and if plants will be impacted or destroyed over time, the consumers depending on the plants will die from starvation and disturb the energy flow in the ecosystem. Along with this, plants are also related to abiotic factors such as maintenance of oxygen and carbon dioxide in the atmosphere, so the balance of these gases will also get disturbed.

Estimate the volume of a human heart (in mL) using the following measurements/assumptions: Blood flow through the aorta is approximately 11.2 cm/s The diameter of the aorta is approximately 3.0 cm Assume the heart pumps its own volume with each beat Assume a pulse rate of 67 beats per minute.
Answer:
The correct answer is 70.92 ml.
Explanation:
Based on the given question, the rate of the flow of blood through the aorta (v) is 11.2 cm/s.
The given diameter of aorta is 3.0 cm
Thus, the radius (r) of aorta will be, 3.0/2 = 1.5 cm
The cross-sectional area of the aorta (A) will be calculated by using the formula, πr²
= π ×(1.5)² cm²
= 2.25 π cm²
The pulse rate given is 67 beats per minute, therefore, time taken for 67 beats is 60 seconds, hence, time taken for 1 beat will be 60/67 second
Now the volume of the heart will be,
= A × v × t
= 2.25 π cm² × 11.2 cm/s × 60/67 s
= 70.92 cm³
As 1 cm³ is equal to 1 ml. So, the volume of a human heart will be 70.92 ml.

Answer:
C. 2 short, 2 long
Explanation:
In addition to the natural loss of muscle mass that occurs as we move into our older years, changes in lifestyle, such as transition from employment to retirement, also account for a decrease in ___________.
a. stress response
b. energy needs
c. hormones
d. brain activity
Answer:
B. Energy needs
Explanation:
As an individual ages there is a characteristic natural loss of muscle mass that occurs and increases as they move into older years. Changes in lifestyle, such as transition from employment to retirement, also account for a decrease in energy needs. This is because there is less amount of work done during retirement than when an individual is actively working.
The less amount of work is the reason why there is also a corresponding decrease in the energy needs.
Pedigrees are used to help geneticists understand how traits are inherited between generations. The Romanovs, a Russian royal family, had a history of hemophilia, a sex-linked disorder that is determined by a recessive allele on the X chromosome.
A genetic pedigree is shown. Irene is a carrier. Her husband is not a carrier. Her children Waldemar and Henry have hemophilia.
What is the best evidence to prove that Irene was heterozygous for hemophilia?
Alice carried the recessive allele.
Alexandra carried the recessive allele.
Frederick carried the recessive allele.
Waldemar carried the recessive allele.
Answer:
Waldemar carried the recessive allele.
Explanation:
The carrier is the individual that has the affected allele or mutation but does not express the trait, or might express it in different levels. Although, as the person carries the mutation, she or he might transmit the genetic mutation associated with a disease to the progeny. In general, these diseases are inherited as recessive traits.
So, in the exposed example we know that:
hemophilia is a sex-linked disorderhemophilia is determined by a recessive allele on the X chromosome.Irene is a carrier.Her husband is not a carrier.Her children Waldemar and Henry have hemophilia.If Irene is a carrier, this means that she is heterozygous and that her genotype is X⁺X⁻ (Being the symbol + the dominant allele, and - the recessive one for that expresses the trait)
The fact that Irene´s husband is not a carrier means that his genotype is X⁺Y
Their boys Waldemar and Henry have hemophilia, so both their genotypes are X⁻Y
The best evidence to prove that Irene was heterozygous for hemophilia is that Alice carried the recessive allele.
Alice is Irene´s Mother, and she is a carrier as well. Irene´s father, Louis, is not a carrier, so she could have inherited a dominant allele from her father and a recessive allele from her mother, X⁺X⁻, or she could have inherited two dominant alleles from both her parents X⁺X⁺. This is not proof enough of Irene being heterozygous. The fact that Alexandra, Irene´s sister, was also a carrier does not say anything about Irene´s genotype, because they could both share the same genotype or not. This is not proof of Irene being heterozygous.Frederick (her brother) was hemophilic. He received a recessive allele from Alice, but this does not say anything about Irene´s genotype. The fact that Waldemar (her son) was hemophilic, is the best evidence to prove that Irene was heterozygous for hemophilia. Walderman received the Y chromosome from his father and an X chromosome from his mother. The X chromosome that he received from his mother carried the recessive allele for the trait, and this is why he had hemophilia. This means that there is no best evidence for Irene´s genotype than her son´s genotype.

The medulla oblongs ya controls the contraction and relaxation of the blank causing the lungs to inflate and deflate during breathing.
Answer:
This question includes some errors, the question should be written as:
The medulla oblongata controls the contraction and relaxation of the ______ causing the lungs to inflate and deflate during breathing.
Although there are no options, the answer is generally RESPIRATORY MUSCLES i.e. diaphragm and intercostal muscles
Explanation:
Breathing is an involuntary action required to take place in order to get oxygen into the system and carbon dioxide out of the system. However, the process of breathing is neurally controlled by brain portion called RESPIRATORY CONTROL CENTERS.
The Medulla oblongata located in the hindbrain is one of the two respiratory control centers (the other being the PONS). The medulla sends nerve signals to the muscles responsible for bringing about the ventilation process i.e. the DIAPHRAGM and INTERCOSTAL MUSCLES.
This nerve impulse brings about the contraction of the diaphragm, which is the major respiratory muscle, and intercostal muscle causing the lungs to inflate and allow the entry of oxygen-containing air. On the other hand, it also brings about the relaxation of these muscles causing the lungs to deflate allowing the expelling of air.
Please help me come up with an answer for this question thankyou so much! Compare and contrast the processes of cellular respiration and photosynthesis. Think of as many similarities and differences as you can (things to consider: inputs and outputs, the role of energy, the types of organisms that do each process, the location within cells)
Explanation:
The end result is glucose, with oxygen being the waste product. The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.
Suggest an intracellular regulatory molecule (from your text) that growth factors might stimulate to control cell division. Please describe how it works.
Answer:
E2F transcription factors
Explanation:
The E2F transcription factors (TFs) encode intracellular factors associated with the control of the cell cycle. E2F are TFs that bind to promoter consensus sequences in order to activate transcription. These TFs control the expression of target genes involved in cell proliferation including, among others, genes for DNA replication and mitotic activation. Moreover, the E2F proteins also may act as a link between cell fate and the cell cycle. The retinoblastoma (Rb) is a protein that modulates the activity of the E2F family of TFs, and it has been shown that the Rb/E2F pathway is a key molecular mechanism associated with cell proliferation.

What type of transport occurs in the cell membrane when a person does sports and is consuming alcohol?
Cellular transport: it is the exchange of substances through the plasma membrane, which is a semipermeable membrane. Transport routes are through the cell membrane
It allows the metabolism waste to be expelled from its interior It allows the movement of substances that it synthesizes as hormones. Metabolic energy: is the way in which it acquires nutrients through processes of incorporation into the cell of nutrients dissolved in water.
Therefore, when the person consumes alcohol in excess the ce transport is part of the disincorporation of toxic waste, while when the person does sports, and is supposed to have a balanced diet, the cellular transport uses it for his metabolic energy.

Which mode of genetic recombination is matched correctly with its description? transduction—virus transfers genes from one bacteria to another conjugation—involves splitting of one cell and results in two identical cells binary fission—requires direct cell-to-cell contact of bacteria transformation—uses a pilus to transmit genetic information between bacteria
Answer:
transduction—virus transfers genes from one bacteria to another
Explanation:
Transduction is a mechanism of recombination where DNA fragments are inserted into bacteria by a viral vector. The mechanism of transduction is commonly used by molecular biology laboratories to insert gene fragments into both bacterial and mammalian cells.
Conjugation is the genetic mechanism in which bacteria transfer genetic information among them by direct contact.
Binary fission is the most common type of asexual reproduction in bacteria. In binary fission, the DNA molecule is replicated and, subsequently, the bacterial cell is divided into two daughter cells with identical genetic material.
Finally, the transformation is the mechanism of horizontal gene transfer in which one bacterium takes up genetic information into the surrounding environment and incorporates it into its genome.

There are two primary models of the universe. One is the expanding model, which says that the universe is constantly increasing in size. The other is, the steady state model, which says that the universe is approximately constant in size and shape. What evidence would you expect to see if the expanding model were correct?
Answer:
Ok, suppose that the universe is expanding:
If the universe is expanding, then the distance between "fixed" points in the universe (we can set the fixed points as planets, galaxies, etc) would change with the time.
This means that, if the distance between the Earth and a given star or planet (that is not in our nearby region) should change as time goes by.
Now, this was actually observed:
There is something called the doppler effect:
In a short way, if an object is moving away, the light that comes from that object will have a red shift (it seems a little more reddish than it actually is)
If the object is moving towards us, the light that comes from the object will have a blue shift (it seems a little more blueish than it actually is)
Those shifts can be observed from the Earth, so from that is safe to conclude that the expanding model is actually correct.
Answer:
Observing objects in the sky that gradually move away from Earth could prove that the expanding model is correct.

kidney.
A pancreas
B urethra
C kidney
D gall bladder
Answer:
C. Kidney
Explanation:
The kidney is a vital organ in the human body. It is bean shaped and helps in the filtration of toxic substances and wastes from the body fluids which is then reabsorbed into the bloodstream.
The kidney also controls the level of water, pH and sodium levels. It however controls the blood pH by excretion of hydrogen ions and forming bicarbonate which ensures the blood pH is within its optimal and normal range.
Answer:
kidneys
Explanation:
The kidneys are the body's filtration system, and are responsible for filtering out the fluids in the body. The biproduct of this is called urine and is removed from the body
