Explanation:
Men are expected to do work that women cannot do. For example going outside and earning money or take decisions that effect the family. These are the thoughts of society and are mostly implemented in households.
Being masculine means that men comparatively have a strong physical ability than women. They can do heavy duty works with ease
Women are expected to sit in the house. According to society women are naive and need to be under the protection of man. Women are expected to be good mothers and obedient wives. They should be able to run the house well.
Being feminine means that women is very delicate and sensitive like a flower. A man has to nourish her and take care of her while the woman will become a beautiful flowers and fill the house with a strong fragrance.
Apart from these men and women are free to do what ever they want because in the 21st century not a lot of these old gender roles are followed. Sometimes the roles get swapped and women work outside just because they want to or because of the economic conditions.

3. Explain the role of organisms in the carbon
cycle and oxygen cycle
What organism? If its plants, they give oxygen during the day and carbon dioxide in the night. While animals give carbon dioxide but take oxygen from the air. These carbon dioxide gas and oxygen gas go to the atmosphere and affect the carbon cycle and oxygen cycle.
Here is the cycle if you want to know more
Plants (give out oxygen) -> Animals (Use oxygen) + (given our carbon dioxide) -> plants (take oxygen)
and so on
Answer:
Plants take carbon from the atmosphere in the form of carbon dioxide during photosynthesis. Plants and animals both release carbon dioxide back into the atmosphere through the process of respiration. When organisms die, some of the carbon in their bodies is stored in the soil, which can be reintroduced into the atmosphere through soil respiration.

_____ allows the cell to grow larger and replicate its DNA in order to prepare for cell division, known as _________. The __________ is the cell that divides to become two new _________.
Answer:
_Mitosis_ allows the cell to grow larger and replicate its DNA in order to prepare for cell division, known as __meiosis__. The __parent cell_ is the cell that divides to become two new _daughter cells__.
Explanation:
The excerpt explains cell division. Let us define some of the terms used:
Mitosis: Mitosis is a stage in the cell cycle where a parent cell divides/replicates into two identical daughter cells. They are identical because they contain the same number of genetic information after division. Mitosis is responsible for cell growth in all somatic cells
Meiosis: Meiosis is a type of cell division in germ (reproductive) cells where the parent cell divides into two daughter cells which contain half the number of genetic information (haploid) as the parent cell.
Parent cell: This refers to the original cell that undergoes division into two or more daughter cells
Daughter cells: The daughter cells are the resulting cells produced after cell division.
For a better understanding of the whole cell division cycle, please read-up the stages contained in both the mitosis and meiosis.

Why are stabilizing proteins neeed to keep the DNA strands separated?
Single-stranded DNA-binding proteins are protected exactly tightly to DNA, but with extremely little carefulness for individual nucleotide sequences.

They accomplish this by interacting strongly with the DNA backbone, via hydrogen bonds with the ribose and phosphates and complementary control interactions with the phosphates.
When the Proteins of DNA Replication DNA Helicases. These proteins attach to the double-stranded DNA and facilitate the separation of the two strands. DNA single-stranded critical proteins.
Although, These proteins bind to the DNA as a stable tetramer the single-stranded structure is produced by the action of the helicases.

Which answer choice accurately depicts the sequence by which blood moves from the pulmonary vein to the body tissues?
Answer:
See the answer below
Explanation:
Oxygen-rich blood flows from the lung through the pulmonary vein to the left atrium of the heart. From there, the blood is pumped through the mitral valve to the left ventricle. The contraction of the left side of the heart sends the oxygenated blood out of the left ventricle through the aortic arch to the major arteries designated to carry blood to the major parts of the body. From the arteries, blood moves to the capillaries and then to the various tissues of the body before returning back to the heart through the vein.
Thus, the sequence of flow of blood from the pulmonary vein to the body tissues can be summarized as:
Pulmonary vein -> Left atrium -> Arteries -> Capillaries -> tissues

This map shows the counties in Montana that are prone to dam failure. If you were in charge of flood control in Montana, where would your biggest areas of concern be? What other data would you collect about these areas or about local weather patterns to help you make a flood-control plan for the state?
Answer:
The focus would be the western side of the state and several counties in the central part of the state because there are many high-risk dams in these areas. Knowing what communities and structures are located around these dams, the average precipitation rate, and projected rainfall totals would be helpful in designing a flood-control plan. Knowing the age and condition of each dam would be important for setting priorities in the plan.

Which marble will experience the least acceleration?
O Marble A
O Marble B
Marble C
Marble D
Answer:
Marble D
Explanation:
According to this question, a group of four students is participating in a marble race. Each marble is said to have different mass but the same force were applied to each of them.
The relationship between the mass, force and acceleration of an object has been explained with the equation: F (force) = mass (m) × acceleration (a).
F = ma
Hence, a = F/m
Based on this, with a constant force, the acceleration is inversely proportional to the mass of an object. This means that when the mass increases, the acceleration decreases and vice versa. Based on the table showing the value for mass and uniform force for each marble, the marble with the highest mass (90) will have the least acceleration (0.66666). This marble is MARBLE D.

Some species of hover flies resemble wasps in body coloring and shape.
How does this characteristic appearance most likely serve as a useful adaptation to some species of hover flies?
a
They are able to pollinate the same flowers as wasps.
b
They can interbreed with wasps and increase species diversity.
c
They can colonize wasp nests without being detected.
d
They are mistaken for wasps and avoided by predators.
Answer:
D they are mistaken by wasps
The most likely explanation for why some species of hover flies resemble wasps in body coloring and shape is that they are mistaken for wasps and avoided by predators (Option D).
What is adaptation?Adaptation refers to the process of change in an organism's traits or characteristics over time in response to environmental pressures such as competition, predation, or changing resource availability. Adaptations can be physical, physiological, or behavioral, and they can help an organism to better survive and reproduce in its environment. For example, an organism that lives in a dry and arid environment might develop adaptations such as a deep root system to tap into subterranean water sources or a reduction in body size to reduce water loss through respiration.
Adaptations can occur through natural selection, where traits that are advantageous for survival are more likely to be passed on to future generations, or through other mechanisms such as genetic drift or mutation.
