Which of the following examples shows the influence coal has had on human activity? Coal use in steam engines led to easier access to goods. Coal use in steam engines allowed people to travel on planes. Coal use in steam engines led to the discovery of natural gas wells.

Explanation:

Answer:

There are 4 systems involved in this activity. these systems are: the skeletal, muscular, circulatory and digestive systems.

Explanation:

To eat a single bite of turkey it is necessary that 4 systems come into play and work together for this activity to be possible.

First, it is necessary that the turkey is brought to your mouth through the movement of its members. In that sense, the resqueletico and muscular systems will act because it is through them that the movements of the members are created.

Then you will need to bite the turkey, chew it, moisten it with saliva, swallow it and digest it. This work will be done with the digestive system that will manage all of these activities.

Finally, your body will need to absorb the elements that make up the turkey pedal that you ate and that were rescued by digestion, these elements are nutrients, proteins and others. All will be absorbed through the work of the circulatory system, which through the blood will carry the elements throughout the body.

Answer:

Hypothesis: IF light is applied, THEN the rate of mitosis will increase

Independent variable: LIGHT

Dependent variable: RATE OF MITOSIS

Explanation:

Hypothesis is a testable explanation given to solve a problem or answer a question. It is usually in the IF, THEN format. A hypothesis of this experiment can read: IF light is applied, THEN the rate of mitosis will increase.

Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the independent variable is the LIGHT.

Dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the RATE OF MITOSIS in a cell.

Answer:

C. Develop new methods to test the hypothesis.

Explanation:

Edge 2020

A scientist will have to develop new methods to test the hypothesis as a

result of humans taking long time to reproduce.

Hypothesis is an explanation for an occurrence or phenomenon in research.

It involves conducting different tests under the same and varying conditions

to confirm if the hypothesis is true which then becomes a law when

universally proven.

Testing of hypothesis is very important which is why developing new

methods which has a lesser time frame to test the hypothesis and not

quitting will be the best option.

It means that the object has color created by the computer since electron microscopes really see in black and white. ... They usually range in sizes between 5-50 micrometers, they are surrounded by a cell membrane, and usually can't be seen without a microscope.

A micrograph is said to be false-colored when there is color created by the

computer involved in the printing of the picture.

A micrograph is a pictorial representation of objects seen under a

microscope. The view of objects under  microscope is usually in black and

white color. The micrograph is therefore meant to also be in black and white.

This is the reason why when there is a color in the micrograph, it is referred

to as being false-colored.

Answer:

Mitosis, part of asexual reproduction because it produces diploids

Explanation:

Meiosis and mitosis are both kinds of cell division.

During mitosis, the DNA of a diploid cell is duplicated and passed on to two daughter cells, each with a diploid genome. This can be used as a method of asexual reproduction (reproduction without the need of a second organism).

Meiosis is a type of cell division specific to sexual reproduction. A diploid parent cell duplicates its DNA, then undergoes two rounds of replication to create four haploid cells. These haploid cells are the gametes. The gametes of two individuals (sperm and egg) fuse during sexual reproduction to create a zygote.

Mitosis, part of asexual reproduction because it produces diploids. The Option A.

Mitosis is a cellular process that involves the division of a cell's nucleus into two identical daughter nuclei. It is commonly associated with asexual reproduction because it allows for the production of genetically identical offspring.

During mitosis, the replicated DNA is evenly distributed to the daughter cells resulting in the preservation of the original genetic material. This process typically occurs in diploid cells, which contain two sets of chromosomes.

Answer:

CHLOROPLAST

Explanation:

As stated in this question, plant cells are capable of producing their own food in form of sugar (glucose) using energy from sunlight in a process called PHOTOSYNTHESIS. Photosynthesis is the process by which green plants and other certain organisms synthesize their own food using light energy.

The ability to carry out this photosynthetic function is embedded in a structure found in plant cells called CHLOROPLAST. Chloroplast contains a pigment called CHLOROPHYLL, which captures light energy from the sun. Generally, the the function of producing sugar in the presence of sunlight (photosynthesis) occurs in the CHLOROPLAST.

Enzymes speedup the chemical reaction.

Explanation:

Enzymes are the molecules which are responsible for speedup of the chemical reaction. In this picture, we can see substrate attached to the active site of the enzyme. This enzyme speedup the chemical reaction and products are formed after completion of chemical reaction. When the chemical reaction is over, the products detached from the enzyme and no decrease occurs in the size of enzyme.

Answer:

These creatures depend on the sea water for nutrients, protection and to move about. At low tide,many of these creatures are exposed to the air, leaving them at risk of predator attacks andoxygen depletion. The whole eco-system of the tide pools would simply not exist without theconstant movement of the tides

Explanation:

The grunion depends on the changes in tide for the survival of its species.

It is because the grunion comes to the beach to lay eggs with the help of high tides. Grunions spawn on the beaches when the tides are at their highest during the full moon and the new moon. The high tides ensures that the eggs will submerged which is important because it allows them to get enough oxygen which is necessary for its survival so we can conclude that grunion depends on the tide for the survival of its species.

Answer:

Transposon is a fragment or sequence of DNA that can move unregulated to any point in the cell genome, leading to a phenomenon called transposition.

Explanation:

Transposon is the name of what was previously known as jumping genes, being a DNA sequence capable of moving freely within a DNA molecule. A transposon can produce mutations by translocation, altering the total amount of nucleotide in DNA molecule.

Genetic changes that are linked to evolutionary processes can be due to the existence of transposons, since they can even induce chromosomal changes.

SIMPLE DIFFUSION transport

Explanation:

According to this question, John could smell the fragrance of his newly bought bottle of cologne all the way up the hall before he can even get into his bedroom, where he usually keeps it. However, he realizes when he got to his bedroom that he left the bottle of cologne uncovered.

The fragrance of the cologne that spreads from the bedroom all through the hall is as a result of SIMPLE DIFFUSION, a form of PASSIVE TRANSPORT. Diffusion is a form of passive transport in which molecules/fluids move from a region of high concentration to a region of low concentration until it is evenly spread. This is the case with John's cologne, which spread from the bedroom where the concentration is high to the hall, where it is low.

Answer:

As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. ... A limiting factor could be the amount of chlorophyll molecules that are absorbing the light.

Answer:

If you continue to increase the intensity of light that a plant receives, what happens? The rate of photosynthesis increases with light intensity. ... The rate of photosynthesis increases and then levels off.. As the light intensity increases the rate of photosynthesis follows (point B on the graph). This means more carbon dioxide is being absorbed by the plant for photosynthesis. So this means more carbon dioxide uptake occurs. The graph shows this increase in carbon dioxide uptake.
