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.

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.

How does Bill define a Gene?
Answer:
DNA, genes and chromosomes are inside every cell in your body. ... Bill defines a gene as a piece of a DNA molecule.
Explanation:
the particles of a gas are
Answer: Low Density
Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states. Their low density gives gases fluidity, which allows gas particles to move rapidly and randomly past one another, expanding or contracting with no fixed positioning. The average distances between the molecules are large enough that interactions between molecules don't interfere with their motion.
Indefinite Shape or Volume
Gases have no definite shape or volume.The random movement of gas molecules allows them to expand or contract to assume the volume of the container holding them. Therefore, a gas's volume refers to the space of the container in which its molecules have range to move. This property results in gases occupying more space than they would in their liquid or solid state. Gases also contract and expand by predictable amounts depending upon changes in temperature and pressure.
Compressibility and Expandability
The low density of gases makes them compressible since their molecules can be positioned far apart from one another. This allows them to move freely to fit into the gaps of space between them. Just as gases are compressible, they are also expandable. The freedom of gas molecules causes them to take the shape of any container in which they are placed, filling the container's volume.
Diffusivity
Given the large amounts of space between gas molecules, two or more gases can mix quickly and easily with one another to form a homogeneous mixture. This process is called diffusion.
Pressure
Gas molecules are in constant motion. They exert pressure, or force per unit area, on the interior surface of their container. The pressure varies according to the amount of gas confined to a given container's volume, the temperature and the pressure.
Explanation:
These are the 5 properties of gas, they don't have particles, they have properties.

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%
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.

Explanation:
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.

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.
