Answer:

absorb heat from the sun

Explanation:

Greenhouse gases are specific type of gases that possess the ability to trap and emit heat/thermal energy in the atmosphere. They are able to do this because of their structure. Examples of greenhouse gases are carbon dioxide (CO2), methane (CH4), chlorofluorocarbon (CFC) etc and are mostly produced via anthropogenic activities.

Greenhouse gases are therefore, produced both artificially (by burning fossil fuels) and naturally and functions to absorb heat from the atmospheric surroundings.

Answer:

absorb heat from the sun

Explanation:

Greenhouse gases absorb heat from the sun.

Answer: Enzymes

Explanation:

Enzymes are those proteins which participate in a chemical reaction without being consumed in the reaction. These enzymes work as a catalyst which speed up the rate of the chemical reaction. The enzyme is responsible for converting the substrate into a product. Pepsin is an enzyme present in the stomach it is activated by hydrochloric acid it is a peptic enzyme which converts proteins into peptones, trypsin and chymotrypsin are the enzymes secreted by the pancreas and it is responsible for digestion of proteins.

Answer:

B.

Explanation:

When you touch something the sensory nerves carry it to the brain while your motor nerves tell you to touch it. So being carried to and from. I also got it right on the quiz.

Sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS. Therefore, the correct statement is option B.

The central nervous system (CNS) includes the brain and the spinal cord responsible for processing information received from peripheral nervous system (PNS) to generate appropriate responses. The brain is the most complex organ of the CNS, carries various functions, including sensation, perception, movement, etc.

Sensory nerves transmit information from sensory receptors, such as those in the skin, muscles, etc. to central nervous system (CNS) and sensory nerves are activated by various types of stimuli.

Motor nerves transmit signals from the CNS to muscles, and other effectors throughout the body. These signals are responsible for activation of muscle contractions, produce movements, and other responses.

Therefore, sensory and motor nerves both work together to perform physiological functions where sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS.

Answer:

XX

Explanation:

ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.

ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres.  XX of the ACTN3 genotype will be advantageous for marathon athletes.

ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance.  This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.

The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.

Therefore, XX of the ACTN3 genotype is advantageous for athletes.

Answer:

Your answer would be "B) They pass oxygen from the air into the blood."

Explanation:

They certainly don't coordinate the movement of the heart, so A isn't an option.

The lungs also don't pump blood through the body, that's the hearts job.

And the lungs do not filter carbon out of the air, which eliminates D.

Therefore your answer is B.

The lungs function in the human body by passing oxygen from the air into the blood.

Gaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.

A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.

In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.

number 4 is node

In the given cladogram the number 4 is node.

A phylogeny, or hypothetical link between groups of creatures, is depicted in a diagram known as a cladogram. A phylogenetic systematics researcher will use a cladogram to depict the groups of organisms being compared, their relationships, and their most recent shared ancestors.

A cladogram might be quite complicated and compare every known form of life, or it can be extremely simple and compare just two or three groups of creatures.

Cladogram design is straightforward but ubiquitous. The creatures being examined, lines, and nodes where those lines intersect make up a cladogram.

Therefore, In the given cladogram the number 4 is node.

Changes  to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

Changes in the genes can affect humans in several ways, such as through genetic mutations that result in changes to the regulation of gene expression and result in the addition or loss of entire genes from the organism. Not all of the genetic mutations lead to expressiable changes, but they may change the protein sequence by changing the polypeptide sequence.

Hence, changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

Answer:

Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade.

Answer is option (C) older, older.

Explanation:

Fossils found in the older layers of a rock (i.e) that are deposited in a deeper position of the Earth, are usually older when compared with the fossils seen in the upper layers of the rock.

Due to the fact that the fossils get accumulated layer upon layer, the older fossils are seen in the bottom layers of the rock.

Answer:

1. A low- pressure weather system can cause a thunderstorm to develop.

2.Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it creates a channel. Once the light is gone the air collapses back in and creates a sound wave that we hear as thunder.

3. One condition that is necessary for a thunderstorm include warm air and moisture.

4. The dangers of a blizzard include getting lost in the snow and freezing to death.

5. In my opinion, a hurricane would be the most difficult storm to face because hurricanes can severely impact your life due to their damage.  For example,winds can damage houses, trees, and any other property. Even if your home is safe, flooding aftermath can occur. When homes are destroyed, people may have to rebuild homes and towns.
