Answer:
D- The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Explanation:
The conservation of mass during cellular respiration can be explained by the fact that after cellular respiration which occurs due to the oxidation of glucose to produce carbon dioxide and water, the number of atoms on the right hand side (RHS) of the reaction remain same as of left hand side (LHS) of the reaction.
The balanced chemical equation is mentioned as under:
C₆H₁₂O₆ + 6 O₂ -> 6 CO₂ + 6H₂O + Energy.
(Glucose) (Oxygen) (Carbon (Water)
dioxide)
If we will see carefully, the number of atoms of each element on RHS & LHS of the equation are same i.e. there are 6 atoms of C, 18 atoms of O and 12 atoms of H on both the sides.

Which two stages are part of the cell cycle but not part of mitosis?
Answer:
Interphase is one of the two
Explanation:
Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis
The mitotic phase and inter phase are the two primary stages of the cell cycle. The cell develops and DNA replication occurs during interphase. The duplicated DNA and cytoplasmic components are segregated and the cell splits during the mitotic phase.
What are the different phases of the cell cycle?The four stages of mitosis are prophase (sometimes known as early prophase and prometaphase), metaphase, anaphase, and telophase. The mitosis movie contains more information about these phases. In cytokinesis, the cell's cytoplasm splits in two to create two new cells.A cell cycle is the sequence of events that occur in a cell as it grows and divides. A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely. Prophase, prometaphase, metaphase, anaphase, and telophase are the stages. Cytokinesis is the final physical cell division that occurs after telophase and is thus sometimes considered a sixth mitotic phase.To learn more about phase of cell refer to:

Sustainability is the ability to sustain production of goods today without impairing our ability to produce goods in the future. Managing resources for their continued use, not just conservation is the ultimate goal of sustainability. Aquaponics is a relatively new branch of food production which utilizes both plant production and fish production in one. In essence, it combines aquaculture and hydroponics (raising plants without soil) in which fish and plants are grown together in one integrated system. The waste from fish provides an organic food source (fertilizer) for the plants and the plants naturally filter the water for the fish. Aquaponics is becoming a popular way to grow both fish and plants because of the advantages it provides to society. What would NOT be an advantage of aquaponics?
A) Evaporative losses are significantly reduced, so water is conserved.
B) Since the fish supply the nutrients needed for plant growth, costly fertilizers are not needed.
C) Vegetables can grow in a climate controlled environment, preventing farming losses from a bad season.
D) Aquaponic systems require electricity to run the system which can be difficult in developing countries.
Answer: Aquaponic systems require electricity to run the system which can be difficult in developing countries.
Answer:aquaponics would create further divide between the rich and poor as electricity is needed to run the system. Underdeveloped countries would essentially be socially excluded from this system

One of the big challenges for a nucleic acid vaccine is actually getting the DNA or RNA to go inside the host cell's membrane. One way to do this is to wrap the nucleic acid up in a little package of macromolecules just like how the golgi body packages things up things we want to export. Based on this description, you would guess that the best thing to package the genetic material would be:
Question Completion:
- a large carbohydrate with partial charges
- a phospholipid
- a nucleic acid carrying
- a negative charge
- a highly polar protein
Answer:
Based on this description, you would guess that the best thing to package the genetic material would be:
- a phospholipid
Explanation:
Since phospholipids work to provide pathways for various substances across cell membranes, they appear to be the best agents or packages for exporting the genetic material of a nucleic acid vaccine. As cell membranes, phospholipids can allow selective passage of some substances into and out of the cells, even though they act as barriers to other molecules and ions.

Difference between pure tone and speech audiometer
Answer:
Speech audiometry was performed on 15 children with secretory otitis media pre-and post-operatively and the findings compared with the pre-and post-operative pure tone audiograms. The results showed that in 30 per cent of cases pre-operatively the speech audiogram suggested a significantly worse hearing ability than that suggested by the pure tone audiogram (PTA). Where a PTA gives a borderline threshold disproportionate parental concern should be taken seriously as the hearing ability may well be worse than the PTA suggests.
A virologist has a cell-free extract of herpes simplex virus (HSV) that has a titer of 6 x 106 infectious virus particles/mL. This virus forms plaques on monolayers of the monkey kidney cell line, CV-1. Following completion of a 10-fold dilution series, the virologist plates 100 microliters of each sample in duplicate.
Required:
What experimental results did he MOST LIKELY observe in the duplicate plates corresponding to his 1:10000 dilution?
Answer:
61 for Plate 1 ,
59 for Plate 2
Explanation:
Given that the original stock has a concentration of 6 * 10^6 infectious virus particles /mL
and it was diluted by 1:10000
New concentration = ( 6 * 10^6 ) / 10000 = 600 infectious virus particles/ mL
Also given that the virologist plates 100 mL of each sample
therefore; 0.1 mL has a count of 60.
The experimental results that he is most likely to observe in the duplicate plates will be ;
61 for (Plate 1) ,

1.If rTMS is deemed a success, this treatment could be applied to other disorders by doing what?
2.Your aunt has Parkinson's. Which of the following treatments is most likely to help her?
Answer: B
Explanation:
1) If rTMS is deemed a success, it could be applied to other disorders by;
Option C; Increasing activity in the brain region involved.
2) The treatment most likely to help your aunt who has parkinson's is;
Option B; DBS
1) rTMS is an acronym that means repetitive transcranial magnetic stimulation. The way it is used is that a coil is held above a part of the brain and recurring high magnetic pulses are targeted at specific brain structures.
This means that the activity of the region of the brain involved is stimulated.
Thus, when applied to other disorders, it could also be a success by increasing the activity in the brain region that is involved.
2) Parkinson's disease is a neurological movement disorder. Now the best way to treat it is to transmit electrical impulses to a specific area of the brain that is responsible for the movement/motor symptoms that Parkinson's disease caused. This is done because electrical impulses interrupt the abnormal activity that occurs in the brain's circuitry which causes the symptoms of the Parkinson's' disease.
The treatment that goes through this process is called Deep Brain Simulation (DBS)

The population of birds will change over time with regard to its beak frequency due to directional selection.
What is natural selection?
Natural selection is a mechanism of evolution that occurs when individuals with certain advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring. This process leads to a gradual change in the genetic makeup of a population over time, as beneficial traits become more common and less advantageous traits become less common.
Natural selection occurs because resources in nature are limited, leading to competition for survival and reproduction. The individuals with traits that best suit them to their environment will have a higher chance of success, while those with less suitable traits are more likely to die or fail to reproduce. Natural selection is a key driver of evolution and is responsible for the diversity of life on Earth.
