Which of the following describes a phenomenon that occurs when we observe plants that wilt?
A. The roots begin to rot, causing them to no longer uptake water.
B. The xylem releases all its water.
C. The stomata close, cutting off transpiration and gas exchange.
D. The plant begins absorbing oxygen and releasing carbon dioxide into the atmosphere.
The xylem releases all its water when we observe plants that wilt.
Answer: Option C
Explanation:
Wilting is a process where the plant loses its rigidity and droops down. To understand it better the water is absorbed through the roots and aids in the functioning of the plant. The excessive water is stored inside the vacuole when during water scarcity releases water.
But during the drought conditions the water is lost completely causing the leaves to shrink. The xylem starts releasing all its water leaving a less surface area. Hence the leaf shrinks and wilting occurs.
Sophia wrote an equation to represent the revenue of a movie theater for one day. She let x represent the number of child tickets sold and y represent the number of adult tickets sold. If a child ticket costs $4, an adult ticket costs $6, and the total revenue for the day was $420, which equation could Sophia use to represent the number of child and adult tickets that were sold?
6 x + 4 y = 420
4 x + 6 y = 420
4 x + 6 y = 840
6 x + 4 y = 840
Answer:
4x + 6y = 420
Explanation:
since x is number of child tickets and y is adult tickets, and $4 is the cost of child tickets and $6 is the cost of adult tickets, that eliminates A and D.
The question also states "for one day", so that elimates C, which C is the equation for two days.
This leaves 4x + 6y = 420

what term means living matter
Answer:
Living’ is something that is alive, something that can grow, move, reproduce, respire and carry out various cellular activities. To understand what is living, we need to look into the features of a living thing in detail. What is Living? Living things are made up of cells and are capable of carrying out various cellular activities.
Explanation:
In your biology class, there was a discussion about climate change. You learned that human activities are changing the composition of Earth's atmosphere, and that levels of greenhouse gases like carbon dioxide (CO2) have been increasing sincepre-industrial times. Your teacher stated that the atmospheric buildup of CO, and other greenhouse gases is largely the result of human activities such as the burning of fossil fuels. One student in your class disagreed. He said that the increase in human populations worldwide is causing the higher level of CO,. His argument is that as people exhale, they release CO, from cellular respiration; more people, more COy. Your class erupted in discussion, and your teacher has asked that you choose a side and research the argument. Working in small groups, create short documentary (3-5 minutes) about how respiration and fossil fuel burning are similar processes. Use data and evidence from peer-reviewed sources to make a claim regarding whether or not one (or both) of these processes can be the root cause of climate change.
Answer:
Below
Explanation:
While your classmate is correct in that respiration does cause the release of CO2, it's inaccurate to say that it has contributed to climate change, and it's especially inaccurate to say it has contributed to the same extend as the use of fossil fuels.
Let's break it down shall we:
When a human breathes, they release 35,000 to 50,000 ppm (parts per million) of CO2 with every exhale. On average, we breathe out 20,000 times a day. Multiply that by the amount of people on Earth, about 7.8 billion, you get 1.716x10^14 breaths a day. Therefore, you have that times 50,000 ppm of CO2 released. That sure is a lot, however, let's look at how much carbon dioxide is released from coal alone in a day. In general, the world consumes over 8.5 million tons of coal a year, and in the US alone 14,000 tons are burnt in one day. When you burn one pound of coal, around 2 pounds of CO2 is released, as the carbon of the coal mixes with the oxygen requiring it to burn. Therefore, 28,000 tons of CO2 is put into the environment from coal alone (not even including all of the other fossil fuels like natural gas and oil), showing how extensive the CO2 burning of fossil fuels is.
Additionally, I want to address the point of increased human population leading to more CO2 from respiration. Consider this, with more people, there is more need for agriculture. Aka, we need to grow more plants in order to sustain our growing population. Plants grow using photosynthesis which needs Carbon Dioxide to begin. Therefore, as our population grows, the amount of CO2 taken from our atmosphere in order to sustain our population actually shows that growing population doesn't necessarily relate to more CO2 from exhalation overall.
14. Which words from the passage show the author's bias toward monarch butterflies? A "Eventually, monarchs reach homes as far north as Canada." B "Most monarch butterflies never live more than two months." c "These beautiful creatures are amazing to watch..." D "They beat their wings slowly and glide so they do not tire too easily."
Answer: C: "These beautiful creatures are amazing to watch."
Explanation: Bias is where an author adds their personal opinion on a topic such as this one on monarch butterflies. Sometimes, authors use bias and it gets away from the facts and the credibility that the topic should bring. In option C, the words "beautiful" and "amazing to watch" steers the reader away from the actual topic with their personal opinions. The other options from the passage include facts about the monarch butterflies and resisting the urge to add comments about how beautiful or interesting they are.

Please help ASAP ill give brainliest to the correct answer!
Answer:
C
Explanation:
<3
A section of a chromosome that contains instructions for building a protein.
What is a gene?A gene is a specific section of DNA, a long molecule that carries genetic information, located on a chromosome. Genes contain the instructions that cells use to make functional molecules called proteins.
Proteins are large molecules that perform a wide variety of functions in the body, including speeding up chemical reactions (as enzymes), building and repairing tissues, and helping to fight infections.
The process by which genetic information in a gene is used to build a protein is called gene expression.
Thus, genes play a critical role in determining the traits and characteristics of an organism, and they are essential for the proper functioning of cells and tissues in the body.
