The net movement of molecules from a region where their initial concentration is higher to a region where their initial concentration is lower is called.

Answers

Answer 1

The net movement of molecules from a region where their initial concentration is higher to a region where their initial concentration is lower is called Diffusion.

Diffusion- A material diffuses when it moves from a region of high concentration to one with a lower concentration. When particles in gases and liquids randomly collide and disperse, diffusion takes place. For living organisms, diffusion is a crucial mechanism because it governs how molecules enter and exit cells.

Cell- The fundamental units of all living organisms are cells. There are many billions of cells in a human body. They provide the body structure, absorb nutrients from meals, turn those food into energy, and perform certain tasks.

What is biotechnology ?

The application of organisms, cells, their components, and molecular equivalents for goods and services is known as biotechnology, which is the merging of natural sciences and engineering sciences. In 1919, Károly Ereky coined the phrase "biotechnology," which he used to describe the utilization of living organisms in the manufacturing of goods from raw materials.

The term "biotechnology" refers to a broad range of practices for altering living things for human benefit, dating back to the domestication of animals and the cultivation of plants, as well as "improvements" made to these through breeding programs that use artificial selection and hybridization. The technologies of cell and tissue culture, as well as genetic engineering, are also used today.

Biological fluids regulate ph values using __________. This is achieved by accepting _________ when ph is low and donating _________ when ph is high.

Answers

Biological fluids regulate pH values using buffers. This is achieved by accepting H⁺ ions when pH is low and donating H⁺ ions when pH is high.

pH is the potential of hydrogen, that gives an idea about the acidity of basicity of a solution. The value of pH ranges from 0 to 14. The pH value of 7 is considered to neutral. Any value below 7 is acidic and any value above 7 is basic.

Buffers are the solutions that resist that change in pH when any acidic or basic component is added to them. A buffer solution consists of a weak acid and its conjugate base or vice versa. The human body consists of natural buffer, which is blood.

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.
