What powers the carbon cycle?
Answer:
[tex] \: [/tex]
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks. Carbon sinks in the land and the ocean each currently take up about one-quarter of anthropogenic carbon emissions each year.

3. The doctor tests the patient's field of view with an astigmatism chart and finds that the patient states that there are blind spots and distorted lines in both eyes he never noticed before. These blinds spots and distortions remain constant. What structure within the eye could cause these distortions? How can you verify your suspicion?
Astigmatism is also a eye condition which is usually evidenced by distorted visions and leading to the creation of an image that is not perfect.
The structure within the eye that would cause the distortions is caused by a deviation in the shape of the lens of the eye or the cornea.
A change that occurs in the shape of the cornea/lens where it is not completely round as it should be usually leads to seeing distorted lines in one's vision and it can occur maybe from birth, even from injury to the eyes.
One can always verify this suspicion by going to seen an optometrist and doing a comprehensive eye examination to verify the condition. The condition is also treatable.

There is a strong relationship between organism complexity and genome size in eukaryotes. Select one: True False
The statement 'There is a strong relationship between organism complexity and genome size in eukaryotes' is FALSE. The genome of an organism is all genetic information of that individual.
The genome is represented by all nucleotide (DNA) sequences that form the genetic makeup of an organism.
The genome is composed of protein-coding genes and non-coding sequences, which often exhibit regulatory functions.
The proportion between protein-coding sequence and non-coding sequence is not linear, thereby the complexity (i.e., the amount of different types of proteins encoded by the genome) and genome size in eukaryotes is variable among species.

Bacterial and viral infections of the brain are rare because the ________ prevents most viruses, proteins, and bacteria from entering the cerebrospinal fluid.
Answer:
blood-brain barrier
Explanation:
The brain is well protected against microbial invasion by cellular barriers, such as the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB). In addition, cells within the central nervous system (CNS) are capable of producing an immune response against invading pathogens.
why do biomes differ
Answer:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
Explanation:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
For example, the types of organisms found in the subtropical desert differ drastically from the organisms found in a tropical rainforest. Each organism is well-adapted to its environment, and a subtropical desert and tropical rainforest are two very different biomes.
If you look at the graph below, you can see that the tropical rainforest has high average temperatures and high precipitation, whereas subtropical deserts have much lower precipitation and great variation in average temperature.

Which is NOT
involved with an
inflammatory
response?
A. fever - increased temperature
B. slowed blood flow
C. white blood cells move to the area of infection
D. inflammation in area
Out of the given answers B. slowed blood flow is not involved with an inflammatory response.
During an inflammatory response, several physiological changes occur in the body to combat infection or injury. Let's briefly discuss the other options to understand their involvement in the inflammatory response:
A. Fever - increased temperature: Fever is a common feature of an inflammatory response. It is caused by the release of certain chemicals called pyrogens that act on the hypothalamus in the brain, raising the body's temperature. The increased temperature helps to enhance the immune response and inhibit the growth of certain pathogens.
C. White blood cells move to the area of infection: Inflammation triggers the recruitment of white blood cells, such as neutrophils and macrophages, to the site of infection or injury. These immune cells play a crucial role in identifying and eliminating pathogens, as well as removing damaged tissue and promoting tissue repair.
D. Inflammation in the area: Inflammation is a hallmark of the inflammatory response. It involves localized redness, swelling, heat, and pain at the site of infection or injury. Inflammation helps to isolate the area, prevent the spread of infection, and promote healing.
B. Slowed blood flow: Slowed blood flow is not a characteristic of the inflammatory response. On the contrary, inflammation often leads to increased blood flow in the affected area, resulting in redness and heat. The increased blood flow facilitates the delivery of immune cells, oxygen, and nutrients to the site, aiding in the immune response and tissue repair.
In conclusion, slowed blood flow is not involved in the inflammatory response, while the other options (fever, white blood cell recruitment, and inflammation) are key components of the inflammatory process. Therefore, the correct answer is B.

Answer:
it flows by the centeral dogma
Answer:
Explanation:
DNA →RNA→ Protein
in the nucleus protein synthesis is copied from DNA onto mRNA thru transcription
messenger mRNA leaves nucleus & goes to cytoplasm attaching to ribosome.
tRNA (transfer RNA) decodes & translate info on the attached mRNA via translation &
gets amino acids corresponding to this information from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are joined together into a chain and thus the protein is formed

which is colder 0 C or 32 F
Answer: we know that the same temperature was named 0°C and 32°F. We write it 0°C = 32°F, and read it: "A temperature of zero degrees Celsius is the same as a temperature of 32 degrees Fahrenheit." Similarly, 0°F = 160/9°C. ... 23°C is 23°C above 0°C. But 23°C = 23*1.8°F and 0°C = 32°F.
Explanation: Mark me brainly please
Answer:
They are the same
Explanation:

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statement into the correct box. some statements may apply to more than one type of microscopes. Some statements may not be used.
Answer: Light microscope:
use a beam of light to produce magnified images
can be used to examine living cells and tissues
Scanning electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Transmission electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Explanation: Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.
Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:
1. Scanning electron microscope(SEM): an electron beam passes over the specimen's surface and displaces electrons which are then focused on a screen to form an image. Images appear in 3-D
2. Transmission electron microscope: electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D
