Human Genome researchers discovered transposons. What are these structures?
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.
How does cellular respiration demonstrate
the conservation of mass?
Cellular respiration is the process by which cells obtain energy from glucose. It can be represented by a chemical reaction which, when balanced, obeys the Law of Conservation of Matter:
C6H1206 + 6O2 ---- 6CO2 + 6H2O
Th number of atoms of reactants equals the number of atoms of products:
six carbon atoms, 12 hydrogen atoms, 18 oxygen atoms
No atoms are created or destroyed in this process, they're just rearranged into different molecules.
We often hear the term "burn" to describe glucose being used by living things for energy. When a substance burns, matter is conserved. It might seem like the burned substance is completely consumed because the products, CO2 and water, are both produced in the gaseous form and are colorless and invisible. The French chemist Antoine Lavoisier was the first to show that mass is conserved in chemical reactions by carrying out combustion reactions in a closed system and capturing the gaseous products.
Cells use cellular respiration to convert glucose into energy for cellular function. A chemical process that, when balanced, complies with the Law of Conservation of Matter might serve as a metaphor for it:
6CO2 + 6H2O = C6H1206 + 6O2
What is cellular respiration?
Cellular respiration converts glucose into ATP, which powers various physiological functions. Cellular respiration involves glycolysis, the citric acid cycle, and oxidative phosphorylation.
Glucose fuels cellular respiration. A balanced chemical reaction represents it:
6CO2 + 6H2O = C6H1206 + 6O2
Reactants and products have equivalent atom counts.
This technique rearranges atoms into molecules without creating or destroying them. Living creatures "burn" glucose for energy. Burning conserves matter. Because CO2 and water are gaseous, colourless, and invisible, it may seem that the burnt material is totally consumed. Antoine Lavoisier was the first to demonstrate mass conservation in chemical reactions by conducting combustion processes in a closed system and catching the gaseous products.

Question: Does light have an effect on the rate of mitosis in a cell?
Hypothesis: If
then
Independent variable:
Dependent variable:
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.
why does the rate of photosynthesis increase when the light intensity increases.
please don't say "because there is more light available to drive the reactions of photosynthesis. "
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.

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

John just bought his favorite kind of
cologne! Every morning, John sprays just a
little on his arm before leaving for school
One day after school he can smell his
cologne all the way up the hall before he
can even get into his bedroom! John is
upset because he is certain this little brother
stole it and sprayed the cologne
everywhere, wasting the whole botse
When he goes into his bedroom he sees
the bottle is still on his nightstand He forgot
to put the lid on this morning. What type of
transport does this represent?
Answer:
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.
The cell cycle is the regular sequence of growth and division that cells undergo.
True or false?
Answer:
True
Explanation:
The regular sequence of growth and division that cells undergo is known as the cell cycle. During the cell cycle, a cell grows, prepares for division, and divides into two new cells, which are called “daughter cells.” Each of the daughter cells then begins the cell cycle again.
Answer:
True
Explanation:
The cell cycle is the sequence of events involved in a cell's growth and division.
The cell spends most of the time in the interphase stage, where it can prepare for cell division by replicating chromosomes.
Then, it undergoes mitosis, where it splits into 2 daughter cells.
So, this statement is true, because cell division is the regular process that cells undergo to grow and divide.
Which of these pairings is correct? PLEASE HURRY
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.
Is mitosis a part of asexual reproduction?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.

"Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next."
Through his work, Mendel published his experiments to explain his findings.
What did his laws of inheritance state?
A.Parental genes are randomly separated from the sex cells so that sex cells contain only one gene of the pair.
B.Each trait of an organism can contain multiple alleles of that trait.
C.Organisms with alternate forms of a gene will express the dominant form of the gene.
D.The inheritance of one trait is not dependent on the inheritance of another.
E.Genes can be transferred from the parent generation directly to the offspring based on the environmental factors surrounding the offspring.

how many body systems are in eating a single bite of turkey? PLSS HELP its duo in abt 6 mins!!
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.

The cells of a plant help the plant maintain its life functions. What part of a plant cell has the function of producing sugar in the presence of sunlight?
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.
