Methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.
What is the importance of methylation in the cell?Methylation has many functions, such as in gene expression, where it can turn genes on or off by altering the way that DNA is packaged, such as by tightening or loosening the gene so that enzymes can access it; in DNA stability, methylation can help protect the genome from damage by stabilizing the DNA structure; and in epigenetic regulation, where it plays an important role.
Hence, methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.

This is a structure of a plant cell which unlike animal cell has a cell wall as well as plasma membrane. It also contains large vacuoles present in the center of the cell. The green color of the plants is due to the presence of chlorophyll which is present in an organelles called chloroplast.
Organelles which are labelled in the cell are
A:Cell membrane
B:Vacuole
C:Nucleus
D:Cytoplasm
E:Chloroplast
F:Cell wall
The given figure represents a plant cell. So, the correct option is C.
What is Plant cell?Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.
In the given figure, labelled organelles function are as follows:
Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.
Thus, the given figure represents a plant cell. So, the correct option is C.

What are some geological characteristics of glaciers in Glacier National Park?
Answer:
The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.

Which two atoms form an ionic bond?
A.sodium and bromine
B. two sodium atoms
C. two oxygen atoms
D fluorine and chlorine
Answer:
sodium and bromine
Explanation:
The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.
Which two atoms form an ionic bond?
Answer : A
Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).
Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.
Thus, the correct answer is option (C).

what factors determine if a species is fit to survive?
Answer: variation, reproduction, and heritability.
Explanation: Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.
Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.

Which type of resources form much more slowly than we use them? A: reusable B: renewable C: nonreusable D: nonrenewable
The type of resources from much more slowly than we use them is non-renewable resource. The correct option is D.
What are nonrenewable resources?A non-renewable resource is a natural resource that cannot be replaced quickly enough by natural means to keep up with consumption.
Carbon-based fossil fuels are one example. With the help of heat and pressure, the original organic matter is converted into a fuel such as oil or gas.
Nonrenewable energy sources are not only affecting our planet's atmosphere by increasing greenhouse gas emissions.
Coal and oil combustion emits particles that can pollute the air, water, and land. Some of these particles are captured and stored, but many are released into the atmosphere.
The use of fossil fuels also disrupts Earth's "carbon budget," which balances carbon in the ocean, earth, and atmosphere.
Thus, the correct option is D.

how do you propagate trees
Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.
Why is it important that mitosis occurs like this
Answer: The cell divides upon these processes during a process known as mitosis. In mitosis, two daughter cells are formed.

How many minutes are there in a 40-hour week?
A:2,000
B:2,400
C:1,400
D:1,200
There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.
What is Unit conversion?
Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.
Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).
The week of 40 hours can be converted into minutes by:
Number of minutes in 1 hour = 60
Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes
Therefore, the correct option is B.
