What is the structural formula for unsaturated fatty acid?

Answers

The generic formula for an unsaturated fatty acid with only one double bond is R-COO–, with R representing the chemical grouping CH3(CH2)mCH=CHCH2(CH2)n. If m=n=7, this would represent the 18-carbon unsaturated fatty acid oleate (oleic acid).

Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.This would happen because

Answers

Answer:

moths would begin becoming lighter as the pollution is reduced

Explanation:

The color of the moths would begin becoming lighter as the pollution is reduced. This is because during the time of high amounts of pollution industrial melanism takes place and the moth's pigmentation becomes a darker tone. This is so that the moths are able to blend in better with its surroundings and survive. Pollution causes sulphur dioxide gas and dark soot deposits which have a greyish dark tone, thats why moths pigmentation turns darker. With pollution reduced moths need a lighter colored pigment to blend into lighter colored objects such as trees and leaves.

The color of the Moths will become lighter as a result of this due to the effect

pollution has on its color.

Industries and factories make use of fuel and when it is burned in generating

sets and other equipment it produces the compound known as Nitrogen

oxide.

The Nitrogen oxide has a brownish color which goes into the atmosphere

where the moths fly in  thereby contact with the gas darkens the color  to

shades of brown. A reduction in the discharge of the gas will lead to it

becoming lighter.

Receptors are needed for which type(s) of cell signaling?

Answers

Answer:

Cell-surface receptors are involved in most of the signaling in multicellular organisms. There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.

Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.

What are receptors?

Receptors are proteins, typically cell surface receptors, that bind to ligands and cause immune system responses.

Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.

Insulin receptors bind insulin, dopamine receptors bind dopamine, nerve growth factor receptors bind nerve growth factor, and so on.

If someone has a heavy weight on his or her chest, explain why after a short time it becomes difficult to breathe, even though the person’s mouth and nose are not affected

Answers

Answer:

When you breathe, air flows from your nose or mouth to your lungs, the lungs expand to allow the air in, and then they contract to remove the air from your body, then you exhale that air.

Then you can see that in the breathing process, your lungs need to expand. If you have a heavy weight on your chest, then the amount that your lungs can expand is really small, then the amount of air that they can have is smaller than normal. This is why is harder to breathe when you have a heavy weight on your chest.

In 2006, an Ethiopian researcher announced the discovery of well-preserved 3.3 million-year-old fossil of a young female hominid. Refer to Figure (F) below. Considering the Hominid trend of evolution, choose which skull would most likely be that most primitive of the three.

Answers

Answer:

Skull three

Explanation:

the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature

It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.

What is the basic evolutionary changes in the group mentioned ?

As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.

It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.

Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.

Explanation:

Technically they all make gluclose but different plants produce different amounts of it.

Yes, this statement is true.

Plants make same kind of sugar but the concentration of sugar is different.

All green plants produce sugars through photosynthesis, a natural process that turns sunlight into energy.Different parts of plants have different concentrations of sugars. These different concentrations form what are called concentration gradients. To move sugars to some areas or cells, up concentration gradients, plants need to use proton pumps, many which require phosphorus and other enzymes.

Which of the following is true about the role of genetic and environmental factors in human health?

A) Genes are the only factor affecting whether or not an idividual will contract a disease.

B) Genetic factors are more important than environmental factors in determining an individual's
personal health risks.

C) Individuals can influence their health by controlling their genetic traits.

D) Environmental factors determine whether or not all genetic traits lead to health issues.

E) Certain environments can lead to an increased risk of developing certain diseases.

Answers

Answer: E) Certain environments can lead to an increased risk of developing certain diseases.

Explanation: This is the most logical answer since environmental factors, such as pollution, can increase one's risk of developing certain diseases.

A. is incorrect because genetic factors are not the only things that affect individual health. One's environment also factors in. If one lives a healthy lifestyle, they can help prevent themselves from developing disease that are more "encouraged" by their genes. An example would be a genetic trait that increases one's risk for heart disease. One can work to avoid heart disease by utilizing a healthier lifestyle.

B. is wrong because environmental factors play an equal role in determining if one will develop some genetically linked diseases.

C. is incorrect because as it stands, one cannot control their genetic traits.

D. is incorrect because some diseases, such as cystic fibrosis and sickle cell anemia are genetically inherited diseases which cannot be prevented by environmental factors. This is not to say that environmental factors are independent of all genetically linked diseases, but not all diseases can be prevented by environmental factors.
