Which of the statements below correctly compares features of plant and animal cells?
Plant cells have a cell membrane, while animal cells have both a cell wall and a cell membrane.
Plant cells have ribosomes only on the rough ER, while animal cells have ribosomes in the cytoplasm.
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles.
Plant cells have chloroplasts but no mitochondria, while animal cells have mitochondria.
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.
What are vacuole?Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole. The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.
Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.
Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.
Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.
Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.
The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.
Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.
The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.

Explanation:
How will a solution change if a base is added?
The hydroxide ion concentration will decrease and lower the pH.
The hydroxide ion concentration will decrease and raise the pH.
The hydrogen ion concentration will increase and lower the pH.
The hydroxide ion concentration will increase and raise the pH.
Answer:
As the concentration of hydrogen ions in a solution increase, the more acidic the solution becomes. As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. ... Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls, and vice versa.

How is nuclear energy generated?
Answer:
Nuclear energy is generated either by Fission of a nucleus into two or more fragments , or by Fusion of two nuclei into one. The nuclear energy is used to superheat steam and then drive a rotor axle inside a generator and then generate electricity.
Answer:Nuclear power comes from nuclear fission
Explanation:Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
Describe the general temperature of ocean currents near the equator and the poles.
Answer:
Currents flowing away from the Equator are generally warm.
Explanation:
That is because the Equatorial regions is the source of warm air and water. Ocean currents flowing from the Equator thus carry this warm water with them. The most prominent example is the Gulf Stream in the Atlantic Ocean, which runs most of the way to the North Pole and brings mild winter climates in its wake to adjacent coastal areas. In the Pacific Ocean the Alaska Current likewise carries warm water northward making Anchorage, Alaska much milder in winter than inland areas with the same latitude.

why velocity is regarded as a vector quantity?
Answer:
Because velocity has magnitude and direction, speed is not a vector quantity since it only has magnitude
For example, if a car is moving backwards with a speed of 40m/s
Your velocity is - 40m/s
Speed is 40m/s

explain what density is. How is it different from weight and mass?
Hey there! I'm happy to help!
Density is how much mass there is per amount of space. The formula for it is mass divided by the volume. How much mass is there per (per means divide) amount of space?
Think of it like a room in a house. If the room only has one person, it isn't going to be very dense with people because there is only one person in the entire room. If there were 100 people, it would be very crowded in that room and the whole room would weigh a lot more. If we make our room the size of a huge convention hall though, 100 people wouldn't make it very crowded,. and it would be less dense. So the amount of people (mass) and the size of the room (volume) affect density.
In that sense, density is kind of like how crowded a thing is.
A hollow watermelon has less density than one that isn't because a watermelon that isn't hollow has more substance inside of it (more mass).
Mass is a factor of density because it measures how much of something there is. It can be related to the people in the room.
Weight is mass but with gravitational influence. A watermelon in space is going to weigh less than a watermelon on Earth because in space there is no gravity and it is floating around, but it will still have the same density just like our room full of people would still be crowded even if the people weighed nothing and were floating around.
On Earth though, we measure mass with terms like pounds, kilograms, etc. We use the term mass over weight because it is more scientifically accurate when calculating density.
