\(\rightsquigarrow\) Global warming is a part of climate change and is partially caused by increased greenhouse gases from burning of fossil fuels, deforestation, agriculture, and other industrial causes.
\(\rightsquigarrow\) The Earth's temperature had already warmed by 1°C compared to pre-industrial levels. This temperature rise may appear small, but small rises in temperature translate into big changes for the world’s climate.
\(\rightsquigarrow\) This is because the amount of extra energy needed to increase the world’s temperature, even by a little, is vast. This extra energy is like force-feeding the global climate system.
●⏩Hotter days
●⏩Rising sea level
●⏩oceans are warming
\(\rightsquigarrow\) Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.
\(\rightsquigarrow\) Rising sea levels will lead to coastal flooding on the Eastern Seaboard, especially in Florida, and in other areas such as the Gulf of Mexico.
\(\rightsquigarrow\) Forests, farms, and cities will face troublesome new pests, heat waves, heavy downpours, and increased flooding. All those factors will damage or destroy agriculture and fisheries.
\(\rightsquigarrow\) Disruption of habitats such as coral reefs and Alpine meadows could drive many plant and animal species to extinction.
\(\rightsquigarrow\) Allergies, asthma, and infectious disease outbreaks will become more common due to increased growth of pollen-producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.
Why can Dry food such as instant noodles, biscuits and potato chips be stored for a long time
Answers
Answer:
Dry foods such as instant noodles, biscuits and potato chips can be stored for a long time because they contain very little moisture. Moisture is what causes food to spoil quickly. Dry foods that contain less than 10 percent of moisture are the perfect candidates for long-term storage. Anything higher than ten could be difficult. 13% is a crucial number, with any foods higher than that posing too high of risk towards bacteria, mold, and fungus growth.
To store dry food properly, it should be kept in a cool and dry place. The storage temperature helps determine the length of storage; the higher the temperature, the shorter the storage time. Dried foods are susceptible to insect contamination and moisture reabsorption and must be properly packaged and stored immediately.

Why or why not? Cite evidence from this text, your own experience, and other literature, art, or history in your answer.
Answers
Answer:
The speaker in the passage is afraid of making the wrong decision when it comes to taking a job offer. This fear has caused him to become indecisive and hesitant, as he weighs the potential risks and rewards of each option. While fear can sometimes be a useful tool in making us more cautious and thoughtful, it can also lead to paralysis and indecision. In my own experience, I have found that fear can help me to carefully evaluate my options and make informed decisions, but only when I am able to manage my fears and not let them overwhelm me. Examples from history and art demonstrate the ways in which fear has both hindered and motivated individuals, highlighting the complex and multifaceted nature of this emotion.

What is the length of BD?
Answers
In the given figure, the length of BD is 14. The correct option is A.
What is the length?Length is the measurement of the extent of something from one end to another, end. The SI unit of length is a meter (m).
Given, that AB is twice the length of BC
BC = CD
DE is a triple of CD
The length of AE is 19
Let's assume BC and CD = x
We have to calculate the length of the CD.
AB = 2x
DE = 3x
Putting the values:
2x + 3x = 49
7x = 49
x = 49 / 7
x = 7
BC and CD = x
7x + 7x = 14x
Therefore, the correct option is A. 14 regarding the given line.

A set of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. find each value, given its distance from the mean.
Answers
The value of each score from the z-score can be calculated using x = 45 + 8.3z
How to determine the distance from the mean?The given parameters are:
Mean = 45Standard deviation = 8.3The z-score is calculated using:
\(z = \frac{x - \mu}{\sigma}\)
This gives
\(z = \frac{x - 45}{8.3}\)
Multiply both sides by 8.3
x - 45 = 8.3z
Add 45 to both sides
x = 45 + 8.3z
Hence, the value of each score from the z-score can be calculated using x = 45 + 8.3z

When the show first aired, it seemed that Khanz knew Khanyi as well as a fan would—through television and social media posts. But it didn't take long for their relationship to grow.
