Farah is doing an experiment that involves calculating the speed of a longitudinal wave. What will most likely happen if she increases the temperature in the room?

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.

What is not a dissolved gas present in the oceanA carbon dioxide

B hydrogen

C oxygen

D nitrogen

Answers

The correct answer is option B, hydrogen.

The majority of the atmospheric gases are found in the sea water solution. In supplementation to oxygen and nitrogen, the most profusely found gas in the atmosphere, that is, carbon dioxide is found in the ample concentrations in the ocean waters.  

However, hydrogen is not present, and if found it is found in minute concentration. Of the gases, nitrogen is the most abundant gas found in seawater, while oxygen is the second most abundant, and carbon dioxide is the most soluble gas, and one of the various constituents, which influences the pH balance of the ocean.  

The answer is B. hydrogen.

Which evidence provides support for the nebular theory. a) scientists have observed the formation of a distant solar system. b) the nebular theory has been proven mathmatically. c) astronomers have observed proplanetary disks around distant newborn stars. d) none of the above

Answers

Evidence that provides support for the nebular theory can be revealed by the third option C) astronomers have observed proplanetary disks around distant newborn stars.  Observing is the most reliable proof for any theory. I'm sure it will help! Regards.

Why are catfish and carp found at the mouth of a river, while trout are found nearer the source?

Answers

Answer:

The correct reason would be "the levels of dissolved oxygen at the mouth of the river and at the source of the river".

The mouth of the river is the region where it flows into the ocean, lake, another river, reservoir, sea et cetera. The level of dissolved oxygen in this region is too low to support great biodiversity.

Organisms like catfish and carp can survive here due to their low oxygen demand. For example, catfish can survive in water with an oxygen content of 2.5 parts per million.

In contrast, the level of dissolved oxygen is higher at the source of the river. Organisms like trout are found here due to their high oxygen need. For example, rainbow trout require minimum 5-6 parts per million dissolved oxygen for its survival.
Catfish and carp require less oxygen than trout. The mouth of a river usually has less oxygen and the area closer to the source has more oxygen, so since catfish and trout require more oxygen they typically are found at the source.

Which stage of the listening process might include an alert posture, appropriate facial expressions, and direct eye contact?selectingrespondingunderstandingrememberingevaluating?

Answers

I believe the answer is the responding stage; which is the fourth stage of listening whee one sues feedback to demonstrate to the speaker their thoughts.

The positive feedback; while the speaker is talking, might include, alert posture, direct eye contact, appropriate facial expressions, head nods and supportive phrases such as "go on" and 'uh-huh". After speaker talks might include requests for clarification or emphatic statements.
