it is curcial the process of mitosis is error free. this is because otherwise healthy cells can
Answer:
It is really crucial that the process of mitosis is error free, otherwise, health cells can grow into giant super cells, also known as cancerous cells.
The process of mitosis and the cycle of the cell is highly regulated so that uncontrolled division of cells do not occur. Mitotic cell division also needs to be error free so that normal daughter cells are produced.
This is why there are different checkpoints in the cell cycle and mitotic cell division itself. Without regulation and checkpoints, health cells might divide uncontrollably and form giant super cells. In reality, these cells are known as cancer cells.
Obviously charged objects attract each other this attraction holds electrons and atoms and holds atoms to one another in many compounds however earnestructs model of the atom field to explain why electrons not pulled into the automatic nucleus by this attraction what change to the atomic model helps solve the problems seeing Rutherford's model
The fact that electrons occupy certain specified energy levels in which they are radiation less solves the problems associated with the Rutherford model.
What is the Bohr-Sommerfeld Model?According to the Bohr-Sommerfeld Model of the atom, the electrons in an atom tend to occupy certain specified energy levels in which they are radiation less.
Recall that following from the Rutherford model and the and the Maxwell's laws, an accelerating charge radiates energy. Thus, the bottle neck is removed by assuming that electrons occupy specific energy levels in which they do not move about an loose energy.

Based on the model simulation of the carbon cycle, what happens when you decrease the plant biomass
Based on the model simulation of the carbon cycle, the atmospheric CO2 increases when you decrease the plant biomass.
What is the Carbon cycle?The carbon cycle may be defined as the biogeochemical cycle by which carbon and its derivatives are swapped among the different zones of the Earth such as the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere.
It is only the plant that uses CO2 for the production of food via the process of photosynthesis and converts it into atmospheric oxygen.
Once the biomass of the plant decreases, the atmospheric level of CO2 increases because now no one on the Earth has the ability to convert carbon dioxide into oxygen.
Therefore, based on the model simulation of the carbon cycle, the atmospheric CO2 increases when you decrease the plant biomass.

Explain the evidence that scientists use to support the Big Bang Theory.
Answer:
See below.
Explanation:
A lot of the evidence is related to the fact that light takes time to travel, one of the core principles underlying relativity.
Space itself is expandingLight has characteristics resembling waves, particularly the wavelength (or frequency), which humans see as color. The doppler effect occurs when an object emits light while moving, compressing or stretching the wavelength and altering the color of the light. The light from a galaxy traveling away from us will look "stretched out," or redshifted, to observers on Earth. A moving object's light is either compressed or blueshifted. This nomenclature is based on the fact that blue light has the largest wavelength and red light has the smallest wavelength for visible light. More frequently than not, invisible light like x-rays or radio waves are used to measure the impact of galaxies.
When we do gaze up at the galaxies in the sky, we notice something unsettling: it seems as though everything in the cosmos is frantically attempting to get away from the planet. Everything is far more redshifted than we would anticipate if galaxies were just randomly cruising through space. It is highly improbable that the earth is at the heart of a galaxy explosion that spans the entire universe in the post-Copernican era of science. Instead, we come to the conclusion that space itself is expanding and that the redshift effect would apply everywhere in the cosmos, not only on Earth.
The fact that space is expanding implies that everything was more compacted in the past. Theoretically, there must have been a time in the past when everything was maximum compressed if space has always been increasing.
We can see the remnants of the big bangSince light travels slowly, whenever we gaze into the remote reaches of the cosmos, we are also doing so in the past. By the turn of the 20th century, technology had evolved to the point where humanity had seen everything inside the observable universe. We discovered that a thick plasma "fog" of stuff from the early cosmos surrounds us on all sides in the form of cosmic background radiation. This suggests that the cosmos did not always exist in its current form. Stars and galaxies were created from a sort of primordial soup that subsequently cooled and concentrated.
We can learn some details about the characteristics of the cosmic background radiation, which will help us understand what the early cosmos was like. The evidence suggests that it was extremely hot and that stable stuff, such atoms and molecules, needed some time to form.
It can be used to explain known phenomenaOne of the best tests for a theory is if it can explain a well-known but yet unrecognized phenomena that is unrelated to the original motivation behind its development. Because the first nucleosynthesis only produced the lightest atoms, the big bang hypothesis, for instance, explains why there is a considerably greater abundance of hydrogen and helium in the universe than heavier elements.
Appendix: Problems and open questionsThe fact that both quantum and relativistic physics apply to the big bang is one of the challenges in researching it. These two models don't work well together, as you may be aware. One issue is that gravity is fundamentally weaker than the other forces, making it very hard to measure gravitational effects at the quantum level. As a result, there is no known quantum explanation of gravity.
Dark matter and dark energy are further issues. Simply put, dark matter is "additional" stuff with gravity but no other interactions. Since dark energy is in charge of space's perpetually accelerating expansion, it is much more intimately associated with the big bang idea.
The baryon asymmetry, an issue with antimatter, is another issue. When matter and antimatter come into contact, they completely destroy one another and transform into energy. When the great bang happened and subatomic particles first started to form, there was only a tiny bit more matter than antimatter; as a result, all that was left was matter. The galaxies are currently made up of this small amount of additional stuff. It is not understood why different amounts of matter and antimatter are produced.
However, the big bang theory is by far the most reliable hypothesis for the early universe's development. It is at the leading edge of contemporary science, therefore it's critical to grasp what evidence is actually being given and to accept new discoveries with a grain of salt.

Fish populations and other aquatic resources are likely to be affected by changes in all of the above i.e., water temperatures, disease and water quality.
a) Water temperatures: Warm water released from industries into the rivers has lesser BOD (biological oxygen demand) than cool water. The marine species which are unable to migrate will die due to the unavailability of oxygen while frequent algal blooms will be present due to no availability of oxygen.
b) Diseases: Increase in toxins and chemicals will increase in the river as a result of the industrial dump. This will cause industrial animals to acquire toxicants in their bodies and will cause several diseases, wounds, and eventually the death of the organism.
c) Water quality: due to warm and toxic water many marine animals will migrate to places with cooler water. there will be increased algal blooms. This will affect the whole food web and hence there will be a loss of biodiversity.
hence all of the above factors will affect Fish populations and other aquatic resources.
