Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries.

Uplift or sinking can be due to tectonic movements of plate or the gravitational adjustment of the Earth's crust.

For example cascadia subduction zone and southern alaska are the sites of ongoing subduction in which pacific and juan de fuca plates slide beneath the north american plate. This is the major movement of rocks that can transform the region . This movement will lead to formation of Aleutian island .

In general uplift means vertical elevation of the Earth's surface in response to natural causes. Example of uplift may include tectonic plate that collide, and push up plate  and land, forming mountains.

When two species compete for resources, (b) both species will decline in fitness. This is because competition takes up energy and resources that could otherwise be used for reproduction and survival.

The better competitor may be able to survive and reproduce more successfully than the poorer competitor, but both species will be less fit than they would be if they did not compete.

Competition for resources is a zero-sum game. This means that one species' gain in resources comes at the expense of the other species' loss of resources. As a result, both species will have to expend more energy and resources to compete, which will leave them less energy and resources for reproduction and survival. This will lead to a decline in the fitness of both species.

The decline in fitness may be more pronounced in the poorer competitor, but both species will be less fit than they would be if they did not compete. For example, two species of birds competing for the same food source may have to spend more time and energy searching for food, which will leave them less time and energy for reproduction and survival. This will lead to a decline in the fitness of both species, even if the better competitor is able to survive and reproduce more successfully.

In some cases, competition for resources can lead to the extinction of one or both species. For example, two species of bacteria competing for the same antibiotic may become resistant to the antibiotic, which will make them more difficult to treat. If one of the species is unable to develop resistance, it may become extinct.

Overall, competition for resources is a negative interaction that can lead to a decline in the fitness of both species involved.

Option 2 (Population of organisms change over time.

Answer:

There are three different types of adaptations:

Behavioural - responses made by an organism that help it to survive/reproduce.

Physiological - a body process that helps an organism to survive/reproduce.

Structural - a feature of an organism's body that helps it to survive/reproduce.

The three types of adaptations are structural adaptations, behavioral adaptations, and physiological adaptations.

Structural adaptations refer to physical features or body structures that help an organism survive and thrive in its environment. Examples include camouflage, sharp claws, or long beaks.

Behavioral adaptations are actions or behaviors that organisms exhibit to improve their chances of survival. This can include migration, hibernation, or social behaviors.

Physiological adaptations are internal changes or processes that aid in an organism's survival. For instance, the ability to regulate body temperature or produce venom.

Adaptations are essential for species to adjust to their surroundings, enhance their chances of survival, and successfully pass on their genetic traits to future generations.

In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.

A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.

Let the fixed charge for the first three days be x and the charge for each extra day be y.

From the given information, we can set up two equations:

For Saritha: \(\rm 3x + 4y = 27 -----(equation 1)\)  

For Susy: \(\rm 3x + 2y = 21 -----(equation 2)\)

We can solve for x and y by using elimination or substitution:

Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:

\(\rm 3x + 4y = 27\)

\(\rm - (6x + 4y = 42)\)

Solving above equations, we get:

\(\rm -3x = -15\)

\(\rm x = 5\)

Substituting x = 5 into one of the equations, we can solve for y:

\(\rm 3(5) + 4y = 27\)

\(\rm 15 + 4y = 27\)

\(\rm 4y = 12\)

\(\rm y = 3\)

Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

Tornadoes and downbursts are two of the most destructive weather phenomena on earth. While both of them can create strong winds, it's important to distinguish between the two to avoid confusion.

To differentiate between the two, the following steps can be taken:After the event has occurred, check the damage path. Tornadoes can leave a relatively narrow, twisted path that can be hundreds of yards long. On the other hand, the damage from a downburst is often straight-lined and can be more widespread in terms of coverage area.Check the direction of the damage. In a tornado, the damage will generally be aligned with the direction of the wind, but in a downburst, the damage will often be perpendicular to the direction of the wind.

Check the atmospheric conditions before the storm. If a tornado is expected, the atmosphere will be charged with energy and very unstable. A downburst, on the other hand, can be caused by a simple thunderstorm. So, if the atmospheric conditions were calm and there was no warning of a tornado, then it was probably a downburst.Vorticity is a term used to describe the rotation of air masses around an axis or an imaginary line. It is a crucial component of supercell formation. When wind shear is present, vorticity can be created in a supercell.

A supercell is a thunderstorm with a rotating updraft. When this happens, a horizontal tube of spinning air is created, and this tube can be stretched and rotated vertically, forming a mesocyclone. A mesocyclone is the precursor to the formation of a tornado. The strength of the vorticity in the mesocyclone is what determines whether a tornado will form or not. The stronger the vorticity, the more likely a tornado will form. Therefore, vorticity plays a significant role in the formation of supercells.

Yeast transformation using LiAc/SS Carrier DNA/PEG method introduces foreign DNA into yeast cells by utilizing chemical treatments and PEG-mediated entry.

Yeast transformation using the LiAc/SS carrier DNA/PEG method is a commonly employed technique to introduce foreign DNA into yeast cells. In this method, yeast cells are treated with lithium acetate (LiAc) and single-stranded carrier DNA, which helps to stabilize and protect the foreign DNA during transformation. Polyethylene glycol (PEG) is then added to facilitate the entry of the DNA into the yeast cells.

The PEG treatment creates temporary pores in the cell membrane, allowing the DNA to enter. Following transformation, the yeast cells are typically subjected to a recovery period before being selected for the presence of the desired DNA. This method is valuable for studying gene function, protein expression, and genetic manipulation in yeast.

One reason why the flagella staining procedure might increase the apparent size of the flagella is because the stain or dye used in the procedure binds to the flagella and makes them thicker.

The flagella themselves are very thin and can be difficult to see under the microscope without staining. When the stain or dye is applied, it binds to the flagella and makes them thicker, which in turn makes them appear larger under the microscope.

The flagella staining procedure is a technique used to visualize the flagella of bacterial cells. The procedure involves applying a stain or dye to the flagella, which then binds to the flagella and makes them more visible under the microscope.

Another reason why the flagella staining procedure might increase the apparent size of the flagella is because the stain or dye used in the procedure enhances the contrast between the flagella and the background. This makes the flagella stand out more and appear larger than they actually are.

Overall, the flagella staining procedure is a valuable tool for visualizing the flagella of bacterial cells. However, it is important to keep in mind that the procedure can increase the apparent size of the flagella due to the binding of the stain or dye and the enhancement of contrast.
