This diagram shows pH ranges from 0 to 14, with 7 being neutral, less than 7 as acidic, and greater than 7 being alkaline (basic). How does pollution affect the pH of a stream?
A. When the acid rain finds its way into the stream, the pH in the stream can increase.
B. When the acid rain finds its way into the stream, the pH in the stream can decrease.
C. Pollution corresponds with decreased photosynthesis, which may cause long-term stability in pH.
Answers
Answer:
B. When the acid rain finds its way into the stream, the pH in the stream can decrease.
Explanation:
The diagram shows the pollution effect of the pH of a stream is: “When the acid rain finds its way into the stream, the pH in the stream can decrease.” Hence, Option B is correct.
What is acid rain?Acid rain refers to precipitation that is unusually acidic, which means that it contains a lot of hydrogen ions. It can refer to rain or any other type of precipitation.
Acid rain often has a pH level between 4-5, which is lower than the neutral pH range that present in most water, including drinking water, which is between 6.5 and 8.5.
Both humans and animals experience respiratory problems as a result. Aquatic ecosystems are impacted when acid rain falls from the sky and into rivers and ponds. The pH of the stream may drop if the acid rain makes its way into it.
Therefore, Option B is correct.

Let O, P, and Q be distinct collinear points with PQ=3. Let P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4.
What is the length of the image segment P′Q′?
Answers
Given:
O, P, and Q be distinct collinear points with PQ=3.
P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4.
To find:
The length of the image segment P'Q'.
Solution:
We know that,
[tex]\text{Scale factor}=\dfrac{\text{Side length of image}}{\text{Corresponding side of original figure}}[/tex]
P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4. So, Segment P'Q' is the image of segment PQ and the scale factor is 4.
[tex]4=\dfrac{P'Q'}{PQ}[/tex]
It is given that PQ=3.
[tex]4=\dfrac{P'Q'}{3}[/tex]
Multiply both sides by 3.
[tex]4\times 3=P'Q'[/tex]
[tex]12=P'Q'[/tex]
Therefore, the length of the image segment P'Q' is 12 units.
A segment in the image is proportionally longer or shorter than the corresponding one in the pre-image.
The length of the image segment P′Q′
Given Information:
O, P, and Q be distinct collinear points with PQ=3.Dilation from point O with scale factor 4.Solution:
Scale factor=Side length of image/corresponding side of original figure
Segment P'Q' is the image of segment PQ and the scale factor is 4.
4=P'Q'/ PQ
It is given that PQ=3
4=P'Q'/3
Multiply both sides by 3.
4*3=P'Q'
12=P'Q'
Therefore, the length of the image segment P'Q' is 12 units.

How does increased soil salinity contribute to desertification?
Answers
Answer: Among the engines of desertification is soil salinization, which is the result of the accumulation of soluble salts in the arable land layers (LUO et al., 2017). As a consequence, there is plant poisoning and increased osmotic pressure on the vegetation inserted in salinized areas.

Answers
Answer:
The world most dominated language is one of the major internet's homogenizing effect on global language patterns.
Explanation:
Countries having world power are most likely providing better network system which are mostly used by them and as a result of this they will be dominating the internet language patterns which leads to the internet's homogenizing effect on global language patterns.
The homogenizing effect of the Internet on global language standards is through the English language, which is widely used on the Internet.
English is a language recognized worldwide as a means of global communication, as it is an easy language to learn and used in business transactions and tourism for example.
Therefore, the dominance of the development of network technologies and the fact that the US is a global power also influence the homogenizing effect of English as a global language and the pattern of use on the internet.

Points O, P, and Q are not collinear and form ∠POQ. Point R is on OP−→− between points O and P. Line l passes through R parallel to PQ¯¯¯¯¯¯¯¯. Line l intersects OQ−→− at point S. Use paper to draw a diagram to represent the situation described.
Which other pairs of segments have lengths in the same ratio as RS to PQ? Select all that apply.
Answers
Answer:
The answer is below
Explanation:
Two triangles are said to be similar to each other if the ratio of their corresponding sides are in the same proportion.
Given triangle ORS and triangle OPQ. ∠ROS = ∠POQ
∠ORS = ∠OPQ (corresponding angles are equal). Also, ∠OSR = ∠OQP (corresponding angles are equal)
Therefore using angle angle similarity theorem, we can say triangle ORS is similar to triangle OPQ.
Therefore:
ratio of RS to PQ = ratio of OR to OP = ratio of OS to OQ
