Why do metals dissolve in acids?
Answer:
In water or acids, the metals trade places with hydrogen. The hydrogen escapes as a gas, and metal atoms, no longer attached to the object from which they came, dissolve in solution.

What is an example of absolute threshold in psychology?
Answer:
In hearing, absolute threshold is the smallest level of tone you can detect, considering you have normal hearing and there are no interfering sounds. For example, you might not be able to hear someone whispering from 20 feet away, but if that person speaks to a normal voice, it may reach your absolute threshold.

Beaker A contains 6 liters of water and 1 osmole of glucose. Beaker B contains 10 liters of water and 2 osmoles of glucose. Which one has the greater osmolarity and by how much?
From the ratio of glucose osmole to the volume of water in the two beakers, beaker B would have the greater osmolarity.
The term osmolarity refers to the number of particles of solutes or osmoles of substances per liter of solution.
In this case, the osmolarity of beaker A can be calculated as;
1 osmole/6 liter
= 0.167 osmolar
The osmolarity of beak B can be calculated as:
2 osmoles/10 liter
= 0.2 osmolar
Thus, beaker B with 0.2 osmolar has the greater osmolarity when compared to beaker A with 0.167 osmolar.
More on calculating concentrations can be found here: rainly.com/question/17329736
Answer: B
beaker A is 0.16 Osm/L and Beaker B is 0.2 Osm/L Beaker B has a greater osmolarity by 0.04 Osm/L

Question 13 of 34
Which of the following is a type of polar attraction?
A A metalic bond
8. A hydrogen bond
C. An ionic bond
A covent bond
Answer: A) Hydrogen Bond
Explanation:
A hydrogen bond occurs when a hydrogen (H) is covalently bound to a more electronegative atom or group forms an electrostatic attraction to another electronegative atom bearing a lone pair of electrons. This is possible due to the polarity of the H-electronegative atom bonds.
Question 1: Some cells produce and secrete high levels of digestive proteins. Which organelles would you expect to be abundant in those cells, and why? Question 2: Explain how active transport helps a nerve cell maintain its resting potential. Question 3: The Atlantic cod is a common fish of the Atlantic Ocean that must drink seawater to meet its water needs. Explain how active transport helps the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions, which are abundant in seawater. ( Will Mark Brainliest). No Nonsense Answers.
Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body
Explain why glucose continues to enter a cell, even when the concentration inside the cell might be higher than outside.
How many ions can move through a protein channel per second (on average)?
Do protein channels have specificity? (i.e. Are they specific about what they let cross the membrane or can any molecule go through any channel?)
Explain how the sodium/potassium pump works. Why does this process require ATP?
Answer:
1)ATP. The concentration of glucose inside of a cell is higher than the concentration outside of that cell, yet glucose continues to enter the cell. ... Two solutions are separated by a selectively permeable membrane that is not permeable to glucose.
2)For transport efficiency, channels have an advantage over carriers in that up to 100 million ions can pass through one open channel each second—a rate 105 times greater than the fastest rate of transport mediated by any known carrier protein.
3)The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in.
in which form of reproduction are fewer offspring produced?
mitosis
asexual reproduction
binary fission
sexual reproduction
Answer:
The answer to this question is B.) asexual reproduction
Explanation:
Hope this helps :) !!!!!!!!!!!!!!!!!
In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.
What is asexual reproduction?
Asexual reproduction is defined as the mode of reproduction in which only single parent is involved and in asexual reproduction fewer offspring are produced. There are several types of asexual reproduction and these are binary fission, spore formation, vegetative reproduction, and fragmentation.
Reproduction has been defined as the process that has been carried out by the living organisms and during the process of the reproduction the living organisms produces their own young ones and feed them. Reproduction has the supreme quality of the living things.
There has been two types of the reproduction and these are the sexual as well as asexual reproduction. The process of the reproduction in which two parents has been involved has said to be sexual mode of reproduction and the process of the reproduction in which only single parent has been involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.
