The described chemical interaction between vinegar and baking soda is an endothermic reaction since it involves the absorption of energy, which causes the mixture to become chilly. The correct option is A.
What is endothermic reaction?A chemical reaction that is endothermic is one that increases the system's enthalpy through a thermodynamic process. A system engages in this process by absorbing energy from the environment, primarily thermal energy.
As a result, an endothermic reaction causes the system's temperature to rise while the environment's temperature drops.
Bonds are typically formed during endothermic processes, which demand energy input. Entropy of the environment is reduced during endothermic reactions.
Endothermic reactions frequently entail physical rather than chemical changes. The potential energy of the products exceeds that of the reactants in an endothermic process.
Thus, the correct option is A.

• How do each of the representative organisms obtain glucose in order to perform cellular respiration?
• How do each of the representative organisms get rid of carbon dioxide, the waste product of cellular respiration?
• How are the processes of cellular respiration & photosynthesis connected? Use the representative organisms to explain your answer.
complete sentences, please
Answer:
Plants obtain glucose in the process of photosynthesis while animals obtain glucose by eating other organisms.
Explanation:
Plants obtain glucose in the process of photosynthesis while animals obtain glucose by eating other organisms. In plants, carbondioxide is used as a raw material in the process of photosynthesis but also small amount of carbondioxide gas is released during respiration from stomata present on leaves while animals has lungs which helps in the removal of carbondioxide gas from the body during breathing.
Cellular respiration and photosynthesis are opposite to each other. respiration is energy releasing process while photosynthesis is a process in which food is produced.

Ice cubes float in water because they are less
Answer: Ice floats because it is less dense than the water. Something denser than water, like a rock, will sink to the bottom. To be able to float, an object must displace fluid with a weight equal to its own weight. The fact that ice floats in water is a bit strange, because most substances are denser when they're solids.

Which of these is a disadvantage of hydroelectric energy ?
A. Is expensive to build or maintain
B. Has high power plant efficiency
C. Has a long power plant life span
D. Reduces greenhouse gas emissions
Answer:
A. Is expensive to build or maintain
Explanation:
Hydroelectric energy is a type of energy which is generated from the flow of water. In this energy, water is allowed to fall from a certain height on the turbine. The moving of turbine produces energy. The main disadvantage of hydroelectric energy is that it is very expensive and require high amount of money for the construction and maintenance of hydroelectric power plant. The machinery used for the production of hydroelectric energy is very costly.

Suzanne has a cat and uses a pet carrier to take her cat to the veterinarian. After a few years, the cat runs away and hides everytime suzanne gets the carrier out. Which beat describes the cats behavior?
Answer:
C. Conditioned
Explanation:
Based on the reaction that the cat is having it seems that the cat has a conditioned response to the carrier being out. This means that the cat has a learned response that is directly associated with a certain stimuli which in this case is the carrier. Since he has a bad experience with the carrier before, he now reacts in a scared manner every time he sees it.
Answer:
C. conditioned

Wooly mammoths became extinct thousands of years ago while other species of mammals that existed at that time still exist today. These other species of mammals most likely exist today because unlike the mammoths they
Answer:
4. had certain inheritable traits that made them to survive
Explanation:
The options are:
1. produced offspring that all had identical inheritable characteristics
2. Did not face a struggle for survival
3. learned to migrate to a new environment
4. had certain inheritable traits that made them to survive
The correct option would be option 4.
This is law of natural selection at play. According to this law, organisms that are better suited to an environment survive, multiply, and pass their survival genes to their offspring. Those that are weakly adapted to the environment usually fade off the environment gradually.
Hence, other species of mammals exist today most likely because they had inheritable traits that made them to survive the changing environment while mammoths became extinct because they were poorly adapted to changing environment.

An earthquake occurred at 6:35:10 am. At what time did the S-wave arrive at a seismic station 4000 km away?
Answer: Around 6:55:40 Am
Explanation:
The velocity of the S wave may depend on the density of the ground.
The speed can go from 1km/s to 8km/s, with an average velocity of 3.25km/s
Now, we can use the equation:
Velocity = distance/time.
Time = distance/velocity.
We have distance = 4000km
and velocity = 3.25km/s
time = 4000km/3.25km/s = 1230.77 seconds.
now, a minute has 60 seconds, so this is:
1230.77/60 = 20.5 minutes. or 20 minutes and 30 seconds
So the earthquake will reach the seismic station around
6:35:10 + 0:20:30 Am
6:55:40 Am

scientific concept for the water cycle
Answer:
Evaporation, condensation, precipitation, Surface Runoff, Infiltration, transpiration
Explanation:
There are six important processes that make up the water cycle. These are:
Evaporation
Evaporation is the process where a liquid, in this case water, changes from its liquid state to a gaseous state. Liquid water becomes water vapor. Although lower air pressure helps promote evaporation, temperature is the primary factor. For example, all of the water in a pot left on a table will eventually evaporate. It may take several weeks. But, if that same pot of water is put on a stove and brought to a boiling temperature, the water will evaporate more quickly.
During the water cycle some of the water in the oceans and freshwater bodies, such as lakes and rivers, is warmed by the sun and evaporates. During the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth.
Condensation
Condensation is the opposite of evaporation. Condensation occurs when a gas is changed into a liquid. Condensation occurs when the temperature of the vapor decreases.
When the water droplets formed from condensation are very small, they remain suspended in the atmosphere. These millions of droplets of suspended water form clouds in the sky or fog at ground level. Water condenses into droplets only when there are small dust particles present around which the droplet can form.
Precipitation
When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs. The raindrops fall to Earth.
As a result of evaporation, condensation and precipitation, water travels from the surface of the Earth goes into the atmosphere, and returns to Earth again.
Surface Runoff
Much of the water that returns to Earth as precipitation runs off the surface of the land, and flows down hill into streams, rivers, ponds and lakes. Small streams flow into larger streams, then into rivers, and eventually the water flows into the ocean.
Surface runoff is an important part of the water cycle because, through surface runoff, much of the water returns again to the oceans, where a great deal of evaporation occurs.
Infiltration
Infiltration is an important process where rain water soaks into the ground, through the soil and underlying rock layers. Some of this water ultimately returns to the surface at springs or in low spots downhill. Some of the water remains underground and is called groundwater.
As the water infiltrates through the soil and rock layers, many of the impurities in the water are filtered out. This filtering process helps clean the water.
Transpiration
One final process is important in the water cycle. As plants absorb water from the soil, the water moves from the roots through the stems to the leaves. Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation through plant leaves is called transpiration. In large forests, an enormous amount of water will transpire through leaves.
