The term "greenhouse gas" refers to a group of gases that also includes carbon dioxide, methane, nitrous oxide, ozone, and organic substances known as chlorofluorocarbons (CFCs).

What role does ozone play in the greenhouse effect?

Two things happen to the Earth's temperature equilibrium as a result of atmospheric ozone. The UV energy from the sun is absorbed by it, warming the stratosphere. Infrared light from the Earth's surface is also absorbed by it, which effectively traps heat in the troposphere.

Carbon dioxide, methane, nitrous oxide, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and ozone in the lower atmosphere are the principal greenhouse gases whose concentrations are growing.

Shira is analyzing samples of red blood cells using a microscope. Her observations are shown.


Shira observes that the shape of Cell A appears normal, while Cell B appears swollen and Cell C is shrunken. The apparent shrinking of Cell C indicates the reaction of the cell to what?

Answers

The shrinking of cell indicates that the solute concentration outside the cell is high is called Osmosis.

Osmosis is one of the important parts of the transportation o minerals and nutrients and tells about the physiology of the plants and osmosis means the transportation of water from higher concentration to lower concentration that is down the gradient and also it can be defined as the movement of water from lower concentration of solute to higher

concentration of solute which is gains the gradient but in terms of solute and this transport takes place in the presence of semi permeable membrane without which osmosis is not possible so according to this in the given situation the cell C shrinks because the concentration of the solute is higher outside the cell than inside the cell which means the concentration of water inside the cell is high and as water moves from high concentration to low concentration so water will move from inside the cell to outside the cell and as water is reduced the cell will shrink and this water can be replaced by any solvent it will behave the same and it can also be said as the process of diffusion or spontaneous net movement of the solvent and this can have different effects on red blood cells.

To reflect the triangle across the x-axis, we'll have to plot the following points:

Given,

A (4, 5)

B (-2, 7)

C (-6, 3)

A' (4, -5)

So, points B' and C' will also be equidistant from the x-axis, similar to the distance of points B and C from x-axis.

Therefore,

B' will be plotted with the coordinates (-2, -7)

and, C' will be plotted with the coordinates (-6, -3)

According to the meaning of a point reflecting through any axis, a point's perpendicular distance from any axis selected as the line of reflection from the image and pre-image is constant.In order to make a mirror image of a point, line, or figure in the X axis, the image has to be reflected over the X axis. The x axis in this situation would be referred to as the axis of reflection.

In order to reflect over the x axis, values of y-coordinates are negated while keeping the value of x-coordinate the same.

So, the correct answer is B' (-2, -7) and C' (-6, -3).

Bottleneck Effect- The bottleneck effect is a phenomena that occurs when a population's gene pool suddenly shrinks as a result of a natural environmental occurrence, a natural disaster, a disease, or human activity. A bias that wasn't there in the initial population will probably result from this shrinkage of the gene pool.
