Answer:
B. The materials used in building cities retain heat
Explanation:
The metropolitan region where the heat island effect is most pronounced is much warmer than the surrounding, natural, rural lands. The materials used in building, along with energy emissions from industry and transportation (cars), are to blame for the effect. For instance, because asphalt is impermeable, heat is reflected back into the air rather of being transferred to the ground like it does by flora and trees. Typically, heat islands are 2 to 6 degrees F warmer. Urban areas stay warm in the nights while the nearby rural regions drop down; the difference can be as high as 20 degrees F.
Communities may experience a rise in heat-related sickness and death, air pollution, air conditioning expenses, and water quality during the summer months due to heat islands.

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.
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.

Explanation:
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.

When a tastant enters the mouth, what are all the structures it passes on its way to
becoming a fully
processed neural signal? Fill in the blanks below.
The food enters the mouth, passing the [1] (tip) of the tongue. It is moved around by the
motion of the tongue and teeth as the food is chewed. Its movement is facilitated by [2]
on the tongue, which are jagged, aiding them in their ability to move food. [3], on the [4]
of the tongue, and [5], located [6], come in contact with the [7].
Both types of papillae have [8] that have receptors for the individual tastes-sweet, sour,
salty, umami (savory), and bitter. Once a tastant is bound to the receptor, it creates a
signal that travels through one of three cranial nerves, depending on the location of the
taste bud. For a taste bud located on the front of the tongue, the signal travels through
the [9]. For a taste bud located on the back of the tongue, the signal travels through the
[10]. For a taste bud located on the middle and back of the tongue, the signal travels
through the [11]. These signals travel to the [12] of the brainstem, where they are
relayed to the [13] for higher processing.
The information given about taste and the tongue is explained below.
How to explain the tongue?
The food enters the mouth passing the TOT (tip) of the tongue. It is moved around by the motion of the tongue and teeth as the food is chewed. Its movement is facilitated by the taste buds on the tongue which are jagged, aiding in their ability to move food.
Fungiform papillae on the side of the tongue and filiform papillae located on the dorsal surface of the tongue come in contact with the tastant.
Both types of papillae have taste buds that have receptors for individual tastes -sweet, sour, salty umami (savory), and bitter. Once a tastant is bound to the receptor it creates a signal that travels through one of the three carnival nerves depending on the location of the taste buds. For taste buds located on the front of the tongue, the signal travels through the facial nerve.
For taste buds located in the middle of the back of the tongue, signals travel through the glossopharyngeal nerve. The signals travel to the nucleus of the solitary tract of the brainstem, where they are relayed to the thalamus for higher processing.
