Answer: A scientific theory concerns nature and is supported by data collected through field observations and experiments.
Explanation:
Scientific theories are only established based on verified facts derived well organized research and experiments using data and other supporting evidences. Theories differ from hypothesis or philosophical sayings which lacks factual and reproducible evidences.
Mrs. Underwoods theory could best be deemed as an assertion because her theory lacks an established and reproducible evidence prepared from data or experimental research to back up or align with her theory.

A portion of a nucleic acid sequence is shown below.
Which term best describes this nucleic acid?
AGC TAT GCC AAA
The study of the gene is called genetics. Genes are always present in pair form.
The correct answer is DNA.
What is DNA?The DNA stands for deoxyribose nucleic acid.it stores all the genetic information and helps in the regulation of the formation of protein and hormones.In DNA, Adenine binds to the thymine and uracil in RNA.
In the question, it has the thymine nitrogenous base.
Hence, we can say that nucleic acid is DNA.

it is where one parent makes a clone of themselves through budding.
What are some "topics" to be considered when discussing the California Current
Ecosystem
Answer: Red tide events
Explanation:
Red tide events causing massive fish die-offs, unprecedented sea ice loss, erosion of coastal wetlands, and bleaching of coral reefs not only impact marine ecosystems but also communities, peoples' well-being, local businesses, and more.
These issues impacting ecosystems and people require solutions that consider ecosystems and people. These types of solutions are Ecosystem-Based Management, which considers social, economic, and ecological trade-offs when deciding how to address these issues.
How does a lack of water in an environment affect the amount of carbon dioxide a plant absorbs?
Answer:
the lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.

The lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth.
What is carbon dioxide?More rapid leaf area development and more total leaf area could translate into more transpiration.
Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.
Carbon dioxide (CO2) is a colorless gas with a sour taste and a slight harsh odor. It is one of the most significant greenhouse gases associated with global warming, but it only makes up a small portion of the atmosphere on Earth (roughly 3 volumes per 10,000).
Therefore, The lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth.

Many aquatic birds secrete waxy organic substances that repel water. The birds use these substances to coat their feathers. An analysis of these substances would reveal that they are composed mostly of…
•Lipids
•Carbohydrates
•Nucleic Acids
•nucleic Acids
Answer:
The correct answer would be - lipids.
Explanation:
Many aquatic birds secrete a waxy organic substance which coats their feathers and this substance allows their feathers to repel the water which is helpful for their flying even after floating in the water.
An analysis of these substances would tell that these substances are composed of lipids as lipids are the only macromolecules that are hydrophobic which means they try to avoid water and not allow water to pass through them.
what's the difference between dominant and recessive alleles
Answer:
The key difference between dominant and recessive alleles is that dominant alleles are the alleles that give the phenotype, masking over the other phenotype, while recessive alleles are the alleles that are suppressed by the dominant allele. Usually, a chromosome contains a number of genes, and they exist in specific places.

In Mendel’s garden, there were only either tall pea plants or short pea plants. How does this go against the widely accepted blending inheritance hypothesis?
Answer:
Mendel noticed plants in his own garden that weren't a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory.

can you create a punnett square for this question?
Answer:
The correct answer is 50%.
Explanation:
In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:
Punnett square:
R R'
R' RR' R'R'
R' RR' R'R'
It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%

Predict how the inability of a species to adapt within a changing environment may contribute to the extinction of that species.
Answer:
B
Explanation:
The Miller-Urey experiment simulated compounds present in the atmosphere of early Earth, lightning, and the evaporation and condensation of atmospheric water. What other information about the conditions on Earth during this time period would you want to know to improve the experiment?
Answer:
The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.
Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.

what do you think the earth looks like in areas with larger numbers of earthquakes and volcanoes
How Earth looks like in areas with larger numbers of earthquakes and volcanoes?
Earth's surface has not always looked like it does today. The movement of Earth's plates is responsible for changing the landscape in dramatic ways causing earthquakes, volcanic eruptions, and the formation of mountains, ocean trenches and mid-ocean ridges.Volcanoes are vents, or openings in Earth's crust, that release ash, gases and steam, and hot liquid rock called lava. On land, volcanoes form when one tectonic plate moves under another. Usually a thin, heavy oceanic plate sub-ducts, or moves under, a thicker continental plate.Learn more:
