how does the size of a hydrocarbon molecule affect the viscosity of a hydrocarbon?

Answers

Answer:

Fuels with large hydrocarbon molecules are more viscous than fuels with small hydrocarbon molecules

Explanation:

Viscosity refers to runniness of a liquid. Fuels with large hydrocarbon molecules are more viscous as longer chains of large hydrocarbon molecules are easily entangled. Fuels with small hydrocarbon molecules are comparatively viscous as shorter chains of small hydrocarbon molecules are less likely to become entangled.

300 million years ago, wisconsin was once covered with rock, while West Virginia was covered with swamps. Why do you think west virginia today produces a lot of bad and oil, while wisconsin does not?

Answers

Answer:

Because of the number of organisms present.

Explanation:

It has been discovered that oil was formed through the accumulation and conversion processes that occurred to the remains of dead animals in the soil.

And since the west Virginia was covered by swamp in about 300 million years ago, it probed to having more animals than that of Wisconsin that was covered by rocks, therefore the possibility of having oils.

Develop an argument from evidence on how human activity can lead to ocean acidification? Further explain what we can do, as humans, to decrease the amount of ocean acidification occurring in aquatic environments.

Answers

Answer

Ocean acidification results from the solubility of CO2 in oceans increasing the H+ concentrations, and depletion of bicarbonates concentrations.

Therefore, human activities which increases the concentration of CO2 in the atmosphere, will raise the atmospheric  CO2 concentration. CO2 is constantly being absorbed by green plants maintaining   its concentration through carbon cycle,Therefore massive deforestation  which removes green plants, cutting  down photosynthesis is one of human activities which  raises CO2 levels of the atmosphere.The CO2 dissolves in  the oceans to raise its acidic levels.Lower pH.

Another source is fossil fuels emissions which add more CO2 to the atmosphere.

What's the most common type of mutation observed in living populations, and what impact does it have on natural selection?

Answers

The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.

Explanation:

(Fill in the blank) In comparing DNA and structural characteristics between plant species, the similarities that appear may indicate a ____________________ __________________between them. (Think of evolution)

Answers

Answer:

(Fill in the blank) When comparing DNA and structural characteristics between plant species, the similarities that appear can indicate a genetic adaptation to a particular environment, between them.

Explanation:

The evolution of the spice indicates that there were changes in the environment where these plants were able to adapt genetically, and not only that but they transmitted it in their generations, that is why many manifest the same genetic code, if this gene was inherited among them it means that the species EVOLVED.

Otherwise, those genes that generate benefits for the plants but are not transmitted in the parent plants will not be considered as an evolutionary change of the species but individual of the plant.

The genetic changes produced by modifications in the environment translate into phenotypic changes, thus generating a more suitable species with a greater chance of survival.

Draw conclusions: Substances that contain carbon and are produced by living things are

called organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water, carbon dioxide, oxygen, and ammonia, are called inorganic.

Some living things, called producers, can produce the organic materials they need (like food) from inorganic matter. All other organisms are consumers; they consume organic matter since they cannot make it themselves.

Do your results show you that trees are producers or consumers?

its a gizmo lol

Answers

Answer: Yes.

Trees are producers

Explanation:

Trees are producers because they have the ability to produce organic materials like sugar.

Trees have green pigments called chlorophyii on their leaves, this pigment trap light energy from the sun and uses carbondioxide and water to photosynthesized in order to produce sugars. Trees undergo a process called photosynthesis which is a process where by green plants uses light energy from sunlight with water and carbondioxide to produce sugars.

Once trees produce sugars, other organism cannot synthesized their own food on their own, so they largely depend on trees for organic materials. Theses organisms are herbivores and sometimes omnivores.

Therefore, Trees are producers.
