Answer:Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall
Explanation:
Answer:
No
Explanation:
Animal cells have cell membranes, but not cell walls. Cell walls are much more structured and are only present in plant cells who also have a cell membrane.

Describe fully what will occur if a plant cell is placed in a solution that has a higher water potential than the cell. Use the following terms in your answer.cell wall, freely permeable, partially permeable, cell surface membrane, vacuole, tonoplast, cytoplasm, solute potential, pressure potential, water potential, turgid, osmosis, protoplast, equilibrium
Answer:
tortinos
Explanation:
hot pizza rolls
When the plant is placed in the higher water potential, the water will diffuse from the higher water potential to the lower water potential and make the plant cell turgid. As a result, the plant cell will swell.
What is the plant cell in a hypotonic solution?When a plant is placed in a hypotonic solution, that means the plant cell has less water potential than the outer side, and as a result, the water will flow from a higher water potential to a lower one. The plant cell membrane is partially permeable, and water will diffuse from the outer to the inner, causing the cell to exert more pressure on the cell wall and swell.
The vacuole will swell too in such a case, and the movement of water is called osmosis. The hypotonic solution has less solute potential, and the flow of water will continue until equilibrium is maintained.
Hence, this is the osmosis process, where the water will flow freely from the outside to the inside of the cell cytoplasm and make the cell turgid.

The graph below represents the effect of enzyme concentration on the reaction rate.
Based on this graph, what can you conclude about the relationship between enzyme concentration and the rate of starch chemical reaction? (ASK 1a1)(DOK1)
Question 4 options:
a. The reaction rate decreases as the enzyme concentration increases
b. The reaction rate increases as the enzyme concentration decreases
c. The reaction rate increases as the enzyme concentration increases
d. The reaction rate is indirectly proportional to the enzyme concentration
Answer:
C
Explanation:
Increasing enzyme concentration will speed up the rate of a reaction, as long as there is substrate available to bind to.
Rate of reaction is directly proportional to the enzyme and substrate concentration. Therefore, option (C) is correct.
What is enzyme- substrate complex ?
An enzyme-substrate complex is what happens when a substrate attaches to an enzyme's active site during a chemical process. Aspects including temperature, pH, co-factors, activators, and inhibitors can affect an enzyme's activity.
A substrate is placed into the active site of the enzyme, or the location where weak bonds can form between two molecules. An enzyme substrate complex is created, and the enzyme's pressures on the substrate cause it to react and turn into the reaction's intended product.
Therefore, option (C) is the correct option as long as there's enough substrate for enzyme to bind and convert to product.

Are the Earth's seasons caused by the differences in the distance
from the Sun throughout the year or the tilt of the Earth's axis?
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Silicon Valley in the San Francisco Bay Area is often called the tech center of the world. The region gets its name from the silicon used in computer chips that were widely manufactured there. Today, this region houses many of the largest computer hardware, software, internet, and digital communication companies in the world. Identify and explain two ways in which an earthquake in this area could affect people in other parts of the world.
Answer:
One way an earthquake could affect people is by disrupting the electric power lines in Silicon Valley. A lack of power could disrupt or shut down major websites that people around the world rely on.
Secondly, an earthquake could cause severe damage to digital communication companies. If that happened, many businesses around the world would suffer. They might not be able to properly access, use, or update the computer applications they rely on for their businesses.

Viruses are particles that Select one: a. contain DNA or RNA which can be injected into a cell. b. have an exterior coat composed of protein. c. can contain an enzyme which catalyzes the reaction to make DNA from the viral RNA. d. All of these answer choices are correct.
Answer:
d. All of these answer choices are correct.
Explanation:
Viruses have an exterior coat composed of protein, the capsid. Inside of it, there is DNA or RNA. When the virus has RNA, it has an enzyme that allows the synthesis of DNA from RNA. This type of virus is a retrovirus since it does the inverse process, from RNA, it gives DNA and not the other way round.
First, as the capsid has proteins, it attaches to a receptor in the cell's membrane. Then the DNA or ARN enters the cell taking it as a host since it uses the cell's structure to replicate the viral DNA and make viral proteins and DNA that then it assembles to form new viruses that will be released to infect other cells.

Consider a major environmental change (like antibiotics entering a person's body). If there are not organisms in a population that have traits that allow them to still continue to survive to reproduce, what would likely happen to that population?
Answer:
The population (of the bacteria) will reduce
Explanation:
This question appear a little confusing because of the structure of the second sentence. However, it appears to describe how an antibiotic works. Antibiotics work against bacteria by either making the environment toxic for the bacteria (which kills it) or inhibiting the growth/reproduction of the bacteria. Both patterns will eventually lead a sharp reduction in the population of the bacteria. Even if what the antibiotic does is to inhibit the reproduction of the bacteria, this act provides the body with an opportunity to fight the "unreproductive" remnants of bacteria thereby leading to the reduction of population of the bacteria.

Answer:
battery
Explanation:
Any source of electricity, the battery, or the power supply is there to maintain the potential difference across a conductor.
To measure this difference we use VOLTMETER - Instrument for measuring potential differences, voltage differences. It is called a voltmeter as it allows the measurement of the potential difference or voltage that exists between two points belonging to an electrical circuit. The voltmeter, therefore, detects the voltage.

Three that live in the savanna are lions, giraffes, and elephants. Choose two of these animals. For each one, describe an adaptation that has enabled it to survive in the savanna. Then tell which which animals in the population would be more likely to survive if a dry season was unusually long.
Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.
