Answer:
2. C - Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
5. D - A desert that has existed for millennia.
Explanation:
2. Predation (A) and fertility (B) are easy scratch-off answers -- given the situation of deforestation, these factors will not influence genetic diversity. Although eating patterns can lead to new adaptations, the best answer is C because it results directly from the issue at hand: deforestation.
5. To limit the amount of population diversity, you would have to maintain the same environment as much as possible. In other words, migration and isolation lead to the creation of new species per Darwin's theory of Natural Selection. For that reason, the only plausible answer here is D.
I truly hope my answers and explanations can help you on this assignment! Be blessed! Be awesome! You've got this!
Many scientific explanations for the origin of DNA and life have been proposed over the years. These hypotheses explain how
inorganic molecules became organic monomers, such as amino acids, sugars, phosphates, and bases. But this still didn't explain
where living things came from. If macromolecules were able to form on early Earth, this still leaves us with the question of how
the polymers would have become self-replicating, a basic criteria for life. There are several ideas but little certainty. Some of the
common ideas include: the RNA world hypothesis, the genes first hypothesis, and the metabolism first hypothesis."
Which of these statements is proposed by the genes first hypothesis?
A)
RNA is highly stable.
B)
The first life forms were self-replicating nucleic acids, such as RNA or DNA
RNA is able to store and pass on genetic information.
D)
RNA contains less nitrogen bases than DNA and thus, is a simpler molecule.
E)
Ribosomal RNA (TRNA) and transfer RNA (TRNA) are the primary molecules
responsible for protein synthesis.
The first life forms were self-replicating nucleic acids, such as RNA or DNA, RNA is able to store and pass on genetic information.
What is the difference between RNA and DNA?There are two differences that determine DNA from RNA,
(a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose, and
(b) RNA has the nucleobase uracil while DNA contains thymine.
Thus, options, A and C are correct, RNA is adapt of both storing genetic data and catalyzing chemical responses.

The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8. Which statement predicts how the stream's ecosystem will most likely be impacted? A The flow rate of the stream will increase B. The flow rate of the stream will decrease. с The number of fish in the stream will increase. D The number of fish in the stream will decrease.
The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.
What is the procedure to indicate the pH of the water stream?The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8.The flow rate of the stream will decrease. The number of fish in the stream will increase and the number of fish in the stream will decrease.
Acid rain is a form of rain with high concentration of hydrogen ions and is acidic in nature. pH of these rains is low and pH is the negative logarithmic of hydrogen ion concentration. It is known as power of hydrogen.
The animal which has the lowest value of pH will be able to tolerate the acid rain more and will be last to die. From the tolerance range of the animals, frogs has the lowest pH for survival which is 4 and it can bear more acid rain than the rest of the animals will be the last to die.
Therefore, The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.

Nondisjunction that occurs during meiosis II produces what?
Answer:
Both of these daughter cells will then go on to divide once more in meiosis II, producing 4 daughter cells, 2 with n+1 and 2 with n-1. Nondisjunction in meiosis II results from the failure of the sister chromatids to separate during anaphase II.

Arturo ran a 3,000-meter race. His running time from start to finish was 10 minutes. What was Arturo's average speed?
Answer:
300 meters/min
Explanation:
average speed = distance / time
(3000 m) / (10 min) = 300 meter per minute
if you need it in meters/sec then just multiply 10 by 60 first and then continue
(3000 m) / (600 sec) = 5 m/s

Outline the process of the Carbon Cycle.
Answer:
Carbon Cycle Definition
Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
Carbon Cycle Steps
Following are the major steps involved in the process of the carbon cycle:
Carbon present in the atmosphere is absorbed by plants for photosynthesis.
These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
