Answer:
2A. central deafness
2B. sensory adaptation
2C. sensorineural deafness
2D. conduction deafness
Explanation:
2A. Listening to excessively loud noises every day over the years that causes loss of stereocilia is an example of central deafness.
Central deafness could lead to deafness either partially or completely of one or both ears due to persistent exposure of the eardrum to loud noise every day for years. when it happens in years that is gradual damage which is usually common compared to sudden deafness. Stereocilia can be damaged with a persistent loud noise.
2B. Hearing construction outside when it first begins but no longer noticing the sound minutes later is an example of sensory adaptation.
In sensory adaptation, the sensory system tends to get adapted to a change in the sound that comes from the environment usually with that sound remaining constant over time. The sensory system get used to the constant stimuli, in this case, the construction outside and with time the system tends to make the stimuli less sensitive.
Sensory adaptation does not fall under the categorization of deafness because, though prolonged exposure of the hears to loud noise could lead to deafness, Sensory adaptation is just an adaptive feature of the hearing system and it could be a loud or low sound or noises.
2C. Difficulty understanding speech, but no damage to ears or ability to understand nonverbal sounds are an example of sensorineural deafness.
Sensorineural deafness involves the ability to hear sound but not to understand speech. Sounds may not be clear but the sufferer could hear a loud noise and it is usually caused if the part of the hearing that collects impulses and sends them to the brain become damaged.
2D. A hole in the tympanic membrane caused by an ear infection is an example of conduction deafness.
The tympanic membrane is also known as the Eardrum, the vibration of this membrane after being hit by stimuli from sounds is part of the fore process to allow the interpretation of sound by the brain. So when there is a hole in the eardrum conduction deafness would occur as the sound wave from the environment is blocked failing to be conducted through the eardrum.

true or false all cells living or dead can produce new living cells
Answer:
TRUE!
Scientist use dead cell embryos to produce living cells
All cells living or dead cannot produce new living cells. Only the living cells can produce new cells. Therefore, the given statement is false.
What is Cell division?Cell division is the process by which a parent cell divides into two new daughter cells. Cell division usually occurs as a part of a larger cell cycle in which the living cell grows and replicates its chromosome before undergoing division.
Cell division occurs in living cells through mitosis and meiosis. The cell division occurs through karyokinesis and cytokinesis. Cell division is a part of the cell cycle. Cell cycle is divided into different phases such as G1 phase, S phase, G2 phase, and M phase.

One of the favorites to win a marathon to be held at sea level has been invited by a sponsor to train in Bolivia (very high altitude place) for three weeks before the race. The sponsor has promised to fly him to the race a day before the race. Based on your understanding of hemoglobin function, would you advice the athlete to accept the invitation or continue with his/her plans to train at low altitude
Answer: At high altitude the body will get prepared for marathon.
Explanation:
The human body is able to adapt the high altitude by long-term and immediate acclimatization. At high altitude the lack of oxygen is sensed at the carotid arteries. It causes the increase in rate of breathing or hyperpnea.
In addition at high altitude the heart beats faster, gradually the body will also compensate itself for low availability of oxygen and get prepared for marathon.

of water. The ecosystem dries up by late summer. What term BEST describes this ecosystem?
A. pond
B. estuary
C. wetland
D. stream bed
Answer:
The correct answer is C. Wetland.
Explanation:
A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.
Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.
When you stop growing, your cells stop dividing.
True
False
Help please
Answer:
Absolutely not mitosis and meiosis don't stop until your heart stops beating.
It is false that When you stop growing, your cells stop dividing.
When you stop growing, it does not mean that all your cells stop dividing. In fact, cells in the human body continue to divide and replenish throughout life, albeit at different rates depending on the type of cell.
The human body is composed of various cell types that have different lifespans and rates of cell division. For example, cells in the skin, gastrointestinal lining, and blood undergo continuous division and turnover to replace old or damaged cells. These tissues are constantly renewing themselves.
However, some cells, such as neurons in the brain and muscle cells, have limited or no capacity for cell division after a certain stage of development. These cells primarily grow in size rather than dividing to create new cells. Therefore, not all cells in the body continue to divide once growth stops.

Earth's climate zones is surrounded by the horizontal belts of different climates such as tropical, dry, temperate, continental, and polar zones.
Firstly, Tropical climate zones which present near the Equator of earth and have high temperatures and high precipitation, while Dry or arid climate zones shows high temperatures and little annual precipitation.
Similarly temperate climate zone observed Earth’s middle latitudes and shows wider temperature and seasonal variations are more distinct.
Continental climate zone observed in mid-latitudes, shows swing of temperatures from cold in winter to warmer, where as polar climate zones shows harsh climate which cannot to support vegetation.

what satellites are used to study expanses of the oceans surface
Answer:
The Geostationary Operational Environmental Satellite-16 (GOES-16) is the first of NOAA's next generation of geostationary weather satellites. Among the many missions of this satellite, it will collect ocean and climate data.
Explanation:
Using satellites, NOAA researchers closely study the ocean. Information gathered by satellites can tell us about ocean bathymetry, sea surface temperature, ocean color, coral reefs, and sea and lake ice. Scientists also use data collection systems on satellites to relay signals from transmitters on the ground to researchers in the field—used in applications such as measuring tidal heights and the migration of whales. Transmitters on satellites also relay position information from emergency beacons to help save lives when people are in distress on boats, airplanes, or in remote areas.
