Answer:

The purpose of the Miller and Urey experiment was to see if organic compounds that could sustain life be created spontaneously in Earth's early atmosphere. They wanted to see if complex molecules of life (eg. Amino acids, etc.) could be created using natural chemical reactions when Earth had harsh conditions.

Answer:

Carbohydrates contain the elements of carbon, hydrogen, and oxygen, and only those elements with a few others.

Lipids/fat contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples include: fats, oils, waxes, and certain vitamins (such as A, D, E, and K).

Proteins contain carbon, hydrogen, and oxygen like the carbohydrates and lipids, but they also contain nitrogen and often sulfur and phosphorus.

Nucleic Acids are the large biomolecules that are essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA. Consisting of Nucleotides, which are the monomers made of three components: a 5-carbon sugar (a phosphate group and a nitrogenous base).

What kind of organism is a heterotroph?
Harman [31]
<span>These organisms are called autotrophs. Autotrophs are also called 'self-feeders,' and they are able to produce energy from sunlight and carbon dioxide and are therefore known as 'producers.' The only autotrophs that we know of are plants and some types of algae. This makes all other organisms heterotrophs</span>

The two popular measures for quantitatively determining if a process is capable are
luda_lava [24]

Answer:

The process capability ratio and the process capability index

Explanation:

The process capability ratio is calculated by dividing the difference of the upper and lower specification limits by six standard deviations. It is a ratio of specification to the process variation. It determines whether a process meets design specifications or not.

Whereas the process capability index measures the proportion of variation between centre of processes and the nearest specification limits.

These two are the statistical measure of a process capability which determine quantitatively that a process is capable or not.

What evolutionary mechanisms might account for the origin and persistence of cell-to-cell signaling systems in prokaryotes?
Fittoniya [83]

Answer:

Quorum sensing.

Explanation:

Quorum sensing may be defined as the phenomena by which the bacteria can detect the specific stimuli and respond towards the cell population density. This process helps in coordinating gene expression.

Quorum sensing is used in prokaryotes for the cell to cell signalling and cell communication as well. The main evolution of quorum sensing in bacteria was to relay the information and helps in cell signalling by releasing the specific toxins. From the evolutionary point, the organism that are capable of quorum sensing would survive more in their environment, adapt well in their environment.

Thus, the answer is quorum sensing.

_ are the group of organisms always found at the base of a food chain. explain why
Alecsey [184]

Answer:

Plants Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
