Two forces are applied on the rope of the magnitude 400N to the right and 600N to the left, as a result of these forces the net force on the object will be 200N. Thus, the correct option is A.
What is Net force?Net force is the resultant force of the total force which is being applied on an object. It is the sum total of the effect of all the forces on an object. Forces which are applied in opposite directions cancel out each other.
If the net force applied on an object is not zero, then it can be said that the object is not in equilibrium, and thus Newton's Second Law can be used to determine the motion of the object.
Here, two forces of different magnitudes and in opposite directions are applied on the rope to pull the rope. The forces are 400N to the right and 600N to the left.
As a result of these forces, the net force applied on the rope can be calculated by:
Net force = Difference between the forces applied in opposite directions or the sum of the forces which are applied in same direction
Net force = 600N (force applied to the left) - 400N (force applied to the right)
Net force = 200 N and the direction will be left as the magnitude is more in left direction than right
Therefore, the correct option is A.

Write a paragraph explaining how adhesion, cohesion and capillary action all enable water to go from the roots to the top of a tall tree.
Answers
Answer:
Capillary action helps bring water up into the roots. But capillary action can only "pull" water up a small distance, after which it cannot overcome gravity. To get water up to all the branches and leaves, the forces of adhesion and cohesion go to work in the plant's xylem to move water to the furthest leaf.
Explanation:
Hope This Helps!
Water is moved up through the plant by capillary action from the soil.
Hydrogen connections between water molecules give them a sticky property that allows them to form droplets. Droplets can stick to the plant because of adhesion.
what is capillary action?Capillary action is the movement of liquid along a solid's surface induced by the attraction of the liquid's molecules to the solid's molecules.
The movement of a liquid across the surface of a solid induced by adhesion between the two is known as capillary action.
The higher the water climbs on its own, the narrower the tube becomes. Water is forced up the columns of cells in the xylem and through fine tubes in the cell wall by adhesion in plants.
The transport of water through the plant is known as capillary action. When the adhesion is stronger than the cohesion, this movement happens. The attraction between water molecules is natural. The transient hydrogen bonds that they form are the source of their attraction.
what is adhesion and cohesion?The act of attaching one thing to another is known as adhesion. Water adheres to the organic tissues of plants thanks to adhesion.
Cohesion is the property that allows molecules of the same substance to stick together.
Water molecules are held together by cohesion in plants. Intermolecular attraction leads liquids to create a top or outer layer that acts like a thin film.
The shape of water drops is determined by surface tension, which also holds structures together as they absorb water.

Answers
Epistasis is genetic phenomenon that is defined by an interection of genetic variation loci
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
The interplay of genes that determines phenotype is known as epistasis. Genes may either hide each other, making one "dominant," or they can mix to create a new characteristic. It's the conditional link between two genes that can determine a single phenotype for certain features.
Epistasis is a term used in genetics to describe the interaction of genes at two or more loci, as a consequence of which the gene's impact is influenced by the presence of one or more modifier genes. One gene or allele in the interaction is obscuring the phenotypic expression of the other genes or alleles. Epistatic refers to the gene or allele that masks the impact. The other gene(s) or allele(s) being masked, on the other hand, is/are referred to as hypostatic. Epistasis can be dominant or recessive. The fur colour of Labrador retrievers, which is a polygenic feature, is an example of epistasis. Its fur colour is determined by the interaction of two genes.

Answers
In order for an organism to decompose to the point that only dry bones will remain, it is estimated that in warm and humid environments the process will take roughly three weeks, In which case the options of Days 26-43 as well as after day 50 are correct.
Decomposition is what happens to any dead organic material. Decomposition is when the organic material is broken down into smaller compounds, organic or not. This process is affected by a variety of conditions including:
TemperatureHumidityPresence and species of insectsElements to which the material is exposedand so on. Each of these factors can greatly impact how fast something will decompose.
The question at hand gives us the conditions for the fastest decomposition, given that this process is accelerated in warm and humid conditions. When in these conditions, it is estimated that an organism can take a minimum of three weeks to reach the stage in which all that is left is the skeleton (dry bones).
Three weeks consists of 21 days, however, option 6 that states "Days 18-25" is not being included given that during days 18-21, elements other than bones may still be present. For this reason, the correct answer is any day after day 21, that is, days 22-50+. Therefore, options 5 and 3 can both be considered correct as in those days only dry bones will remain.

Over 99.9% of the solar system is composed of hydrogen and helium. How does this help to explain the size differences between the terrestrial planets and the gas giants?
Answers
Explanation:
Gas giants/Jovian planets are also called the outer planets, they are made of gases, they are large and less dense, more moons. Terrestrial/Rocky planets are also called the inner planets. They are made of rocky surface, denser than Jovians, and small, little or no moons.
The information about the composition of solar system has great significance in providing data about size between the terrestrial planets and the gas giants planets.
The size differences occur between the terrestrial planets and the gas giants due to the presence of different concentration of gases in their compositions. Gas giants planets are also called the outer planets which are made up of gases.
They are large in size but having less density and more moons while on the other hand, terrestrial planets are made of rocky surface. They are also called the inner planets. They are more denser than gas giant planets, small in size and less or no moons so we can conclude that there is a great size differences between the terrestrial planets and the gas giants.

Looking for input and other opinions with the following statement. 'environmental factors influence the rate of natural selection." I am to make a claim on whether I agree or not and why. I agree with the statement. This is because all literature states that with natural selection it's basically the best man/woman wins. I feel that with that statement it directly refers to the environment if food is scarce then the best hunter the best runner is going to get the food first if the weather is changing and it's time to move on or hibernate then the one with the best intuitions will move on or assume hibernation and wont be left to the cold as well as if they are the prey to something else as everything is the best one to keep alert and observant to their surrounding would be the one to survive longer. Although I think that the only downfall to that would be if something happened and the appearance was to change and made them less desirable in that manner but then would in turn help themselves to camouflage to hide better.
Answers
I agree completely.
Environmental factors control evolution through surivial of the fittest, or natural selection. This is not nearly as much the case with humans as wild animals, or early on humans, but it does still come into play. For example, lactose intolerance was erradicated in areas where milk was a primary source of nutrients during a famine. The famine was environmental, causing natural selection to elimate lactose intolerant people in the area.
A more basic example is fur color of certain animals. They were selected by their environment to survive and pass on their genetics, causing the species to evolve.
