A student is given a small amount of unknown tan-colored liquid substance. This unknown liquid is placed into a glass of water and mixed. Despite mixing, the tan liquid remains separated from the water and collects as a large droplet at the top. Which of the macromolecule groups is this liquid MOST likely to be a member of?

Answers

This liquid substance most probably be a member of the group of lipids. Liquids which do not dissolve in water are called hydrophobic substances. Nonpolar substances exhibit this effect. Lipids are a class of large molecules or macromolecules which are hydrophobic. Lipids include cholesterol, fat, and phospholipids.

Answer:

Why did Juliet's parents think she was crying in Act IV of Romeo and Juliet?A. because Romeo was banished
B. because Tybalt was dead
C. because she didn't want to marry Paris

Answers

Juliet's parents thought she was crying in Act IV of Romeo and Juliet because Tybalt was dead. The correct answer is B.

Option B, because Tybalt was dead, is the right answer.

The urge following why Romeo all of a sudden wanted Tybalt dead on the earth that he murdered Mercutio, his dearest friend. Romeo requires Tybalt dead as recoupment for him killing Mercutio. He confirms this when he states, "Now, Tybalt, take the "miscreant" back repeatedly that late thou gave me, for the soul of Mercutio, is nevertheless a small path over our crowns, waiting for thine to linger including him. Either I or Thou or both of us must go with him".

In their experiment to form a primitive living cell, Urey and Miller set up various flasks with water vapor and the gases CO2, CH4, and H2. One flask also had electrodes to generate spark; another flask had electrodes to generate spark; another flask had everything but electrodes. Which of the flasks showed presence of coacervates, and why?A: only the flask with the electrodes because the electrodes were a source of electricity that simulated lighting.
B: only the flask without electrodes because the electricity generated from electrodes would have destroyed the coacervates.

Answers

The correct answer should be A.only the flask with the electrodes because the electrodes were a source of electricity that simulated lighting.

According to their experiment, only the flask with the electrodes could show presence of coacervates because it needed an energy source in order to fully simulate earth's early atmosphere.

Which explanation is most likely the reason for the evolution of a larger brain in humans?The size of the human brain increases the more it is used.
A larger brain allows humans to solve complex problems.
The size of the human brain has changed randomly over time due to mutations.
A large brain increases humans’ ability to fight and survive disease.

Answers

The most likely reason for the evolution of a larger brain in humans is that the size of the human brain increases the more it is used. The correct option is A. Evolution findings show that as the activities of man increase and as he advance in using his brain to develop new things that are needed for his convenience, the brain size also continues to increase.

Answer:

A large brain allows humans to solve complex problems.

Explanation:

The large brain in humans has enabled them to solve a complex problem in of the real world and also enabled them to survive more as compared to humans with the smaller brains.

In seven million years the size of the human brain is tripled. That allows them to store and process a huge amount of information and also help to interact with the people in the surrounding better.

Hence, the correct answer would be option B.

Cellular respiration is best associated with the: A.) Golgi apparatus. B.) ribosome. C.) mitochondrion. D.) chloroplast. E.) microtubule.

Answers

Answer:

Explanation:

Cellular respiration is best associated with the organelle mitochondrion.

Final answer:

Cellular respiration is associated with the mitochondria, where cells generate energy by breaking down glucose and other food molecules

Explanation:

Cellular respiration is best associated with the mitochondrion (option C). This is an important cellular process that enables cells to generate energy by breaking down glucose and other food molecules in the presence of oxygen. The mitochondria in our cells carry out this process, converting the chemical energy in food to a form the cell can use. While the Golgi apparatus, ribosome, chloroplast, and microtubule have crucial roles within the cell, they are not directly related to or responsible for cellular respiration.
