If a scientist is studying a coral reef, including both the biotic and abiotic components, he/she is studying ecosystem ecology.
Ecosystem ecology is the interdisciplinary study of the biotic (living) and abiotic (non-living) elements of ecosystems as well as their interactions. This branch of science studies how ecosystems function and how chemicals, bedrock, soil, plants, and animals connect to these components.Ecosystem ecology explores the biological and physical components of an ecosystem as well as their interactions. In the end, this clarifies how to preserve high-quality water and profitable commodities production. Ecosystem ecology places a lot of emphasis on ecological mechanisms and functional processes that keep ecosystems' structure and services functioning. These include trophic interactions, breakdown, and primary productivity (the creation of biomass).Studies on ecosystem function have significantly increased our understanding of sustainable forage, fiber, and water production.Therefore, ecosystem ecology is the correct answer.

Found throughout the nervous system, __________ aid and support the function of neurons. a. neurotransmitters b. somas c. glia d. reuptakes please select the best answer from the choices provided a b c d
Answer:
C: glia
Explanation:
I got it right on edge
Functions of neurons supported by glial cells, which provide support and also help increase action potential, hence option c is correct.
What are glial cells?Neurons are the basic functional units of the nervous system, and they create electrical impulses referred to as action potentials, which allow them to transmit data swiftly over large distances.
Glia is also essential for nervous system function, although they primarily serve to support neurons. Despite the complex nature of the nervous system, the nervous system consists of only two main types of nerve cells: neurons and glial cells.
Glial cells clearly provide "support" both for cells such as neurons and structures such as blood vessels, they can also function to increase action potential conduction.
Therefore glia provides support to the function of neurons and helps to generate an action potential, hence option c is correct.

When you get a scratch, the cells in your body will multiply until?
When you get a scratch, the cells in your body will multiply until they reach the cells gathering at the other side of the wound.
What is a wound?A wound is a cut that occurs on the body. When the scratch or the wound occurs, the skin cells that are around that area are destroyed. When this occurs, the person would feel pain as the blood vessels in that area become affected and the individual begins to bleed. The bleeding that the individual experiences is in proportion to the extent of the wound that the individual has.
Having said this, we know that the cells are affected when there is a scratch on the body. The scratch depends on the impact of the object that caused the injury in the body.
Immediately the scratch occurs, the cells that are around the affected area begins to multiply. The multiplication of the cells is in order to cover the area and cause the wound to heal.
Thus, when you get a scratch, the cells in your body will multiply until they reach the cells gathering at the other side of the wound.

Why are thick or dense smears less likely to provide a good smear preparation for microscopic.
Thick or dense smears less likely to provide a good smear preparation for microscopic because it will diminish the amount of light that can pass through making it difficult to visualize the morphology of single cells under the microscope. Some times the stain can't penetrate all of the bacteria.
What is a microscopic smear?A smear is a microscopic specimen.A swab or loop, or the edge of another slide, is used to spread the sample to be examined, such as blood or microbial culture, thinly and unevenly across the slide.Smear preparation involves spreading a small amount of sample on a slide and air drying the film before staining and microscopy.The conventional method, blood film method, drop and rest method, and water-wash method are the four types of smearing methods.Smear microscopy entails collecting a biological sample (typically sputum or other clinical material), fixing it thinly on a glass slide, and staining it with a dye that binds specifically to mycobacteria (making them easier to identify under a microscope).To learn more about microscopic smear :

Based on cell theory, the statements that can confidently be made regarding these unidentified plants and seeds are: Living cells inside the seeds divide to generate the new plant cells and Tissues in both the plants and the seeds are made of cells.
The cell theory has 3 main aspects which are that all living cells arise from the cells before, all living things are made up of one or more cells and cells are the building blocks of life. The cell theory helps to differentiate living cells from non-living ones.
Based on this theory, we know that the plants which are grown from the seeds and the seeds themselves are made up of cells. Both the plant and the seeds are living cells.
As all cells arise from pre-existing cells, we know that the new plant cells were made from the division of the cells present in the seeds.

revolution of the earth around the sun
The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (usually 21 or 22 December) and in the Southern Hemisphere, this is the June solstice usually 20 or 21 June.
2. The Sun lies directly over 23 1/2o south. Occurring during the astrological sign of Capricorn, 23 1/2o south latitude is called the Tropic of Capricorn. Continuing to March 21st (i.e. spring equinox) the Earth has positioned itself similar to that which occurs in September, only on the other side of the Sun.
3. June 21
The latitude of 23 ½ degrees north is known as the Tropic of Cancer, and it is the northern boundary of the tropics. Question: On June 21, the subsolar point is at about 23 1/2 degrees north.
4. In 2020, the Sun will cross the celestial equator from north to south on September 22, at 13:30 UTC. Because of time zone differences, the equinox will take place on September 23, 2020 at locations that are at least 10:30 hours ahead of UTC.
5. December 21st was the Winter Solstice in the northern hemisphere. That's the day when Earth's north pole was pointed completely away from the Sun. If you lived north of the Arctic Circle, like Santa Claus, you would have experienced 24 hours of darkness. It was the day Sun never rose.
6. The farthest south that the sun's rays shine directly is latitude 23 ½ degrees south, the Tropic of Capricorn. This is the southern boundary of the tropics. On this day, the area north of the Arctic Circle gets no sunlight, and the area south of the Antarctic Circle gets 24 hours of light.
7. Tropic of Capricorn, 23 1/2 degrees S. Tropic of Cancer, 23 1/2 degrees N. Arctic Circle, 66 1/2 degrees N. Antarctic Circle, 66 1/2 degrees S. North Pole, 90 .
8. Tropic of Capricorn: 23.5 degrees south of equator. ... at midday on December 21 is 90-36-23.5 = 30.5 degrees; on March 21
9. equator
The equator is an imaginary line drawn right around Earth's middle, like a belt. It divides Earth into the Northern Hemisphere and the Southern Hemisphere. Another imaginary line drawn straight through Earth connecting the North Pole to the South Pole is Earth's axis of rotation.
10. A day is the amount of time it takes a planet to finish one rotation on its axis. It takes Earth approximately 365 days and 6 hours to orbit the Sun. It takes Earth approximately 24 hours — 1 day — to rotate on its axis. So, our year is not an exact number of days.

A cell containing a certain concentration of salt is placed in a solution. the cell neither shrinks nor swells. therefore, the solution is said to be:________
A cell with a certain salt concentration is immersed in a solution. The cell does not shrink or swell. The solution is thus said to be isotonic to the cell.
What exactly is an isotonic cell?A cell in an isotonic solution is in harmony with its surroundings, which means that the concentrations of solutes within and outside are comparable (iso means equal in Latin). Because there is no concentration gradient in this state, hence there is no substantial movement of water in or out.
What exactly are hypotonic cells?A solution outside a cell is said to be hypotonic if it contains a lower solute concentration than the cytoplasm. Water diffuses into cell as a result of osmotic pressure, and the cell frequently appears turgid, meaning bloated.
What is the distinction between isotonic, hypotonic, and hypertonic fluids?Hypotonic fluid has less fluid, carbohydrates, plus salt than blood. Hypertonic fluid contains more fluid, carbohydrates, and salt then blood. Isotonic fluid, carbohydrates, and salt concentrations are similar in blood.
