Prenatal medical procedure in which high frequency sound waves are directed into a pregnant woman's abdomen

LuckyWell [14K]

Prenatal medical procedure in which high frequency sound waves are directed into a pregnant woman's abdomen is called ultrasound sonography.

Ultrasound imaging or sonography is often used in medicine as the nondestructive procedure to visualize muscles and many internal organs as well as fetuses during routine and emergency prenatal care..

What kind of monomers make up lipids

bogdanovich [222]

The kind of monomers that make up the lipids are the fatty acid and the glycerol.

Lipids or the fats are the organic compounds containing two kinds of monomers called the fatty acid and the glycerol. Fatty acids are the carboxylic acids made up of a hydrocarbon chain with a terminal hydroxyl group. Glycerol is an alcohol containing three carbon, five hydrogen and multiple hydroxyl groups (usually three) and it forms the back bone of all the lipids. The most abundant lipid called the triglycerides are the esters of fatty acids and glycerol.

Which of the following situations accurately describes a difference between a food chain and a food web? Select one:

Natasha2012 [34]

Lets look at your first question. A food chain is a linear (line) relationship between organisms. It shows who eats what and who gets eaten. The energy is passed up the chain from one organisms to the next. A food web is a series of interconnected food chains. It can show one organism being preyed upon by several predators. The answer choice A is really referring to an energy pyramid, but it is true in any ecosystem that only 10% of available energy is passed to the next trophic level. B and C are both true statements as well. D is completely false because 90% of energy is lost, not retained. So with that said, there is more than one correct answer here. I have included a diagram so you can see the difference between the two.

For Question 8, the key to understanding this is that sunlight is the main source of energy for any ecosystem. Plants (autotrophs) use the sunlight to convert it to sugars (glucose) which is a compound that heterotrophs can utilize. This process is called photosynthesis. :-)

Question 9: So in a food chain, you typically start with the producers (plants), then to the primary consumer, then secondary consumer, then tertiary consumer, and in some cases you may have a quaternary consumer. That is 4 links. However, we are forgetting the role of decomposers at all levels of this food chain, and that would add an extra link. In summary, you wouldn't typically see more than 5 links in a food chain.

I hope all of my explanations are helpful! Good luck! :-)
