In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell. Thus option B is correct.
What are the function of plant cell wall ?
Plant Cell wall is composed of cellulose which is a sugar which is a rigid structure that provides support and protection to the plant cell from any external damage.
Mechanical strength can be provided due to the presence of skeletal framework in cellulosic microfibrils.
The various shapes of plant cell due to cell wall, the additional wall component include pectin and/or lignin
Growth of plant cell can also depends on the elastic and plastic nature of cell walls.
The transport of intracellular substances between plant cells can be done by cell wall.
It occurs in two ways such as apoplastic and symplastic transport.

Answer:
A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease.

Mitosis is a type of cell division. organize the images below to show the steps of mitosis.
Answer:
The correct order is F, E, C, G, H, A, D, and B (look at the image in the attached files)
Explanation:
Interphase: Stages G1, S, and G2. At this point probably, the chromatin duplication has already occurred, but it is still lax or dispersed. It has not condensed yet. Two pairs of centrioles are outside the nucleus (FIGURE F) Prophase: Centrioles move forward to the opposite poles of the cell. Chromatin is condensed and individual chromosomes are now visible. The nuclear membrane breaks into many pieces. Spindle apparatus -microtubules- forms. (FIGURE E)Metaphase: The polar and the kinetochore fibers drive each individual chromosome to the equatorial plane. This stage ends when all the chromosomes are completely arranged in the medial area. (FIGURE C)Anaphase: Sister chromatids separate and move to the opposite poles of the cells, driven by the microtubules. In each pole, there are a pair of centrioles (FIGURE G and H). Telophase: The nuclear membrane rearranges. Each sister chromatid becomes now a new chromosome. There is a pair of centrioles outside each of the nuclei. (FIGURE A)Cytokinesis occurs at the end of the cell division. The rest of the cell is divided into two new daughter cells. Each daughter cell is an identical copy of the other cell, with the exact same genetic material (FIGURE D). Decondensation of the genetic material of each new cell (FIGURE B).Answer:

demonstrating?
A. mechanical energy
B. potential energy
C. kinetic energy
D. two of the above
The correct option is C.
Kinetic energy.
Explanation:
It is kinetic energy because the chemical energy stores in food is converted to kinetic energy and this is because kinetic energy is the energy in motion.
When a person is running, the energy the person is using is kinetic energy because is the energy the person possess by virtue of his body in motion and it is the energy required to accelerate a body with mass from rest.

The chemical equation for photosynthesis suggests that blowing on a glass of water placed in a sunbeam will produce glucose and oxygen.
Compare the chemical equation to actual photosynthesis and explain why no reaction occurs. Explain your answer in 1-2 sentences.
(2 points)
Answer:
Plants need chlorophyll to conduct photosynthesis
Explanation:
The process of forming food and energy through the plants in the presence of some inorganic compounds and sun energy is called photosynthesis.
No reaction will occur when the glass of water is placed in the sunbeam.
The reaction can be explained as:The experimental reaction will include water and atmospheric carbon as the reactant and in the presence of the sunbeam should have produced glucose and oxygen molecules. The actual photosynthetic reaction also includes carbon dioxide and water as the reactants but the process occurs in the presence of the plant pigment called chlorophyll.So, when air is blown in a glass of water in the presence of sunbeam then no photosynthetic reaction will occur as the glass does not contain the photosynthetic pigment called chlorophyll.Therefore, the reaction will not occur because of the absence of chlorophyll.

The white of an egg consists mostly of a protein called ovalbumin. Under normal circumstances, ovalbumin is a sphere-shaped molecule, and the egg white is clear and runny. Why does the cooked egg appear solid and white?
Answer:
Because ovalbumin is denaturated.
Explanation:
When a protein is heated, denaturation occurs. This is a process in which the protein loses its conformation and structure, so we can observe changes in color and viscosity. Before heating, egg white is clear, traslucent and runny. When heated, it turned opaque, in a solid state. This changes indicate that the protein ovalbumin has been denaturated, so it changes its structure and properties.
in general, how does temperture affect the speed of sound in air
Answer:
Air molecules have more energy at higher temperatures, which means they vibrate faster. This allows the sound waves to also travel faster because they are propelled by collisions between the molecules.

Why did the travel agent tell the producer of the video to plant a certain number of trees when he
booked a flight? In your answer, explain how trees affect the carbon cycle
Answer:
The producer booked a ticket on an airplane. When he flies, the plane will add a certain amount of CO2 to the atmosphere. One way to remove CO2 is by planting trees. We know that trees take in CO2 from the atmosphere during photosynthesis. The producer can help keep his travel plan carbon neutral by planting a related number of trees. The trees offset the carbon released into the atmosphere by the airplane.

How'd it go?
Explanation:
During a visit to a desert ecosystem, a student observes the
following:
• A hawk eats a snake.
• A lizard eats a fly.
• A tortoise eats small patches of grass.
• A snake eats a mouse.
Based on student's observations of how each of these organisms
obtain's energy, which of the following statements is the best
conclusion?
A. The hawk is a primary consumer.
B. The grass and the desert tortoise are both primary
consumers.
C. The lizard is a tertiary consumer.
D. The lizard and the snake are secondary consumers
Answer: D) The lizard and the snake are secondary consumers.
Explanation:
Producers are organisms that, simply put, produce their own food. All photosynthesizing plants are considered to be producers. Animals cannot be producers.
Primary consumers eat producers.
Secondary consumers eat primary consumers.
Tertiary consumers eat secondary consumers, and so on.
The lizard eats a fly, which is a primary consumer. This makes the lizard a secondary consumer.
The snake eats a mouse, which is a primary consumer. This makes the snake a secondary consumer.
A) is incorrect because the hawk is a tertiary consumer.
B) is incorrect because grass is a producer, not a consumer
C) is incorrect because the lizard is a secondary consumer
Answer: D. The lizard and the snake are secondary consumers .
Explanation;
Option A is not correct because the hawk is a secondary consumer.
Option B is not correct because the grass is not a primary consumer.
Option C is not correct because the lizard is a secondary consumer.
This leaves us with option D: the snake is a secondary consumer (it eats the mouse) and the lizard is a secondary consumer (it eats the fly). This, option D is the correct answer.

What sort of information do you think should be sent to alien civilizations?
We could send aliens information that is good about us not the bad things. Don't share weaknesses, because that could probably lead to some bad things. We should share valuable info with the aliens.
Answer:
Information about how much we know.
Explanation:
If alien life ever gets a chance to communicate with us and we have a chance to communicate with them then we must show them how much knowledge we hold so they can better understand our customs and what to show us. We will probably show them the key sciences such as Math, Science, Biology, Phycology, Astrology, Astronomy, and our knowledge of technology. We will first show them simple problems we know like 2+4 and 1+1. After we will show them huge amounts of our psychological capabilities like our vast arrays of calculations and formulas. This is just a small fraction of our knowledge we will show them.
