Answer:
all cells come from other cells
What is this called?
Answer:
phototropism.
The two organelles involved in cellular energetics are mitochondria and chloroplasts. While both organelles are involved in cellular energetics, they are only found in specific types of cells.
Mitochondria are found in both animal and plant cells, whereas chloroplasts are only found in plant cells. Organelles are specialized structures present inside cells that perform specific functions.
These functions can include metabolism, transport, and protection. Organelles are generally membrane-bound, meaning they are surrounded by a membrane that separates their internal components from the rest of the cell. Organelles work together in a coordinated fashion to maintain the overall health and function of the cell.
Cellular energetics refers to the processes by which cells obtain and utilize energy. This energy is used for a variety of functions, including movement, growth, and reproduction. The two organelles most closely associated with cellular energetics are mitochondria and chloroplasts.

It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance
When an object constructed has a natural frequency which is equal to the frequency of a nearby external vibration, the amplitude of the vibration of the object will increase due to the resonance effect which occurs because the external frequency matches up with the natural frequency of the constructed object.
The negative effect of resonance is the increase in the amplitude of the vibration of the object which might lead to the partial or complete collapse of the constructed object.
Hence we can conclude that It is risky to build something whose naturalfrequency is matched with external vibrations because of ; The effect of resonance

Answer:Most objects have at least one natural frequency of vibration. If a nearby object vibrates at the same frequency, it can cause resonance. Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.

Answer:
a. Sucrose is present in the plant cells that provide them energy and helps in the metabolic process of the plants. The pH of the plant cells will increase and their cellular environment becomes basic in nature. The uptake of sucrose is pH specific and the acidic condition in the environment allows the uptake of sucrose. The decrease in pH concentration in the environment increases the pH inside the cells.
b. The inhibitor of ATP inhibits the production and functioning of the ATP molecule. This effects the sucrose transport in the plant cells. As the sucrose movement requires the ATP and it is a active transport. The ATP inhibition decreases the sucrose uptake in the plant cells and the sucrose concentration decreases inside the plant cells.
Sucrose uptake in plant cells seems to require an acidic environment, brought about by the active transport of protons which requires ATP. An inhibitor of ATP regeneration would likely slow or stop this transport and, in turn, sucrose absorption.
The reported results suggest that the process of sucrose uptake in plant cells involves acidification of the surrounding medium prior to sucrose absorption. This can be explained by the proton-sucrose symport mechanism, in which protons (H+ ions) are actively pumped out of the cell in a process that requires ATP energy. When these protons combine with water (H2O) in the cell's environment, they form hydronium ions (H3O+), resulting in a lower pH or more acidic environment. Only after this acidic environment is established does sucrose uptake begin.
Based on this mechanism, introducing an inhibitor of ATP regeneration would be expected to decrease or halt this process, since ATP is required for the active transportation of protons. With less ATP, fewer protons will be pumped out, leading to a less acidic environment and, thus, lower sucrose uptake. This hypothesis is supported by how phosphofructokinase, a key enzyme in glycolysis (ATP production), is affected by low pH levels.

Answer: (5 differences)
A plant cell is larger than an animal cell. The shape of a plant cell is a fixed rectangular shape, whereas an animal cell is mostly round and irregular in shape. Plant cells store energy in the form of scratch while animal cells store energy in the form of complex carbohydrates and glycogen.
(5 similarities)
Image result for What are some of the differences and similarities between a plant cell and an animal cell
Both animal and plant cells are eukaryotic cells and have several similarities. The similarities include common organelles like cell membrane, cell nucleus, mitochondria, endoplasmic reticulum, ribosomes and golgi apparatus.
