Which position must the moon be in for you to see a full moon on Earth?
Answer:
the entire day side of the moon.
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.

D: Steam
At an incineration facility, 90% of the garbage's volume is lost. The last 10% is in the form of Ash.
What do you mean by Incineration facility?An Incineration facility may be defined as a facility that tolerates municipal solid wastes and disposes of them through the method of combustion.
When this facility tolerates the wastes, approximately 80 to 90% of its volume gets lost. The remaining is left in the form of ash. It is formed just bottom of the incinerator unit.
Therefore, it is mentioned above.

5.) Morgan buys a male python from a snake dealer who tells him that the snake carries the albino allele. Morgan mates the snake with an albino female, and ten normally pigmented offspring are produced with zero albino offspring. Morgan rushes back to the snake dealer and demands his money back stating that the male he bought is not heterozygous for the albino allele because all of its offspring had normal pigmentation. Is Morgan’s position supported by genetic theory? Why?
From the illustration, Morgan's claim could be valid and his position is supported by genetic theory.
Dominant/recessive allelesIt can be inferred from the claim of the snake dealer that albinism in male python is a recessive trait. If this claim is true, let us assume that the albino allele is represented by b and the alternate form is B.
The genotype of the snake Morgan bought will be Bb as claimed by the dealer.
Morgan mated Bb snake with an albino snake which would be bb.
Bb x bb
Bb Bb bb bb
Thus, the mating should have produced albino to non-albino snakes in the ratio 1:1.

Explanation:
what molecules do plants take in for their energy needs
Answer:
Photosynthesis is the process by which plants produce food. Plants use their leaves to trap light energy during photosynthesis. Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to manufacture cellulose and starch, among other things.
Another explanation:
Also, photosynthesis is a chemical reaction that takes place in a plant's leaves and requires both chlorophyll and light energy. Chlorophyll in leaves aids in the conversion of carbon dioxide and water into oxygen and glucose during photosynthesis. Glucose serves as a critical source of nutrition for the plant.

Answer:
C
Explanation:

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.

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
