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.

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

Answer:
Velocity
Explanation:
Given the change in positive (direction) over time we are given the velocity formula.
V = Change in direction/Change in time
Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.

Where in a cell would you most likely find DNA?
Your answer is → compartment within the cell called a nucleus
In a cell, DNA would most likely be found inside the nucleus which is known as the controlling center of the cell.
What is DNA?DNA stands for Deoxyribonucleic acid. It is considered the most common genetic material of living organisms. The genetic information of a particular organism is encoded with these segments, known as DNA.
The process of transcription is initiated within the nucleus of the cell which transforms DNA into mRNA. It is known as the brain of the cell. Due to compartmentalization in eukaryotic organisms, a well-defined nucleus has appeared which helps in the transfer of genetic information from one generation to the next.
Therefore, the nucleus is the region where DNA is most likely found within the cell.

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

Which of the following choices is a component in the community of a wetlands
ecosystem?
A. Water
B. Sunlight
C. Soil
D. Frog
Answer: Water
Explanation:
A community is the occupied space by a population of two or more species. Water is a community component of a wetland ecosystem. Thus, option A is correct.
What is a wetland ecosystem?Wetland is a type of ecosystem that comprises water reservoirs and has an excess of stored water in the form of bogs, marshes, and swamps. A wetland ecosystem includes many biotic and abiotic factors that interact and live together.
The wetland ecosystem is characterized by the presence of water throughout all the years. It is a valuable ecosystem that absorbs excess precipitation so as to avoid flooding and soil erosions. Hydrology, soils, and biology are the main components of the ecosystem.
Therefore, option A. water is the component of the wetland ecosystem.

Which characteristic best explains why lentic ecosystems are more responsive to seasonal changes than lotic ecosystems?
Photosynthetic organisms keep lentic ecosystems warmer during the winter season.
Lentic ecosystems are susceptible to temperature due to their low dissolved oxygen.
Lotic ecosystems have low nutrient levels, making them more sensitive to temperature.
Lentic ecosystems tend to have smaller volumes of water compared to lotic ecosystems.
Lentic ecosystems tend to have smaller volumes of water compared to Lotic ecosystems.
Lentic ecosystem consists of still (stagnant) volume of water and good examples include ponds,lakes, basins etc.
Lotic ecosystem , on the other hand consists of a flowing volume of water and examples include seas, oceans, rivers etc.
The Lentic ecosystem usually is usually still and is affected by seasonal changes as it contains smaller volume of water when compared to the Lotic ecosystem which has a high volume.
Seasonal changes such as summer or winter affects the Lentic system easily as the small volume of water gets heated up and frozen easily which encourages more evaporation and freezing respectively.
