Why would a plant cell not burst while an animal cell would undergo cytolysis in a hypotonic solution?
The plant cell has a large central vacuole and creates a stronger exterior.
The plant cell has a rigid cell wall and the pressure from the central vacuoles causes the stiffness of the plant and animal cells do not have a cell wall therefore the boundary of the cell is weaker.
The plant cell is stronger because it has the chloroplast and causes a strong boundary that support the cell due to the glucose that is made from the process of photosynthesis.

What is the volume of a cube with a length of 3cm an a height of 4cm an a width of 10cm
Answer:
120 cm
Explanation:
volume is length x width x height so 3 x 4 is 12 and 12 x 10 is 120cm
Answer:
120 cm^3
Explanation:
V= width x length x height
3 x 4 x 10 = 120
and when you multiply centimeters,
cm x cm = cm^2
cm x cm x cm = cm^3
Hope this helps :)
Please Help, I Am Very Confused By This Question. Photos Are Linked!
PLEASE HELP -- Imagine protein X, destined to span the plasma membrane. Assume that the mRNA carrying the genetic message for protein X has already been translated by ribosomes in a cell culture. If you fractionate the cells, in which fraction would you find protein X? Explain by describing its transit through the cell.
Answer:
Protein X would be ultimately present in the subcellular fraction containing membrane fragments
Explanation:
It is possible to trace the synthesis and transport of a membrane protein by the following steps:
1- The amino acids of the membrane protein are joined together in the ribosome to form a polypeptide chain (in this case, the protein X).
2- A signal sequence of the growing polypeptide produces the binding of the ribosome to the membrane of the endoplasmic reticulum (ER) and the insertion of this polypeptide chain into the ER.
3-The protein is released into a vesicle from the ER to be exported to the Golgi complex.
4- The membrane protein is transported by the Golgi complex to the cell membrane by the formation of a secretory vesicle that fuses with the plasma membrane, thus being finally embedded in the lipid bilayer.
Protein X should be present in the subcellular fraction that comprise of membrane fragments
The fraction that should be measured the protein X:
Here the synthesis should be traced and the membrane protein transport should be applied by using the following steps:
Here the amino acids of the membrane protein should be connected together so that the polypeptide chain should be created. A signal sequence with respect to the polypeptide should be grown that generated the ribosome binding. Now the protein should be relased into the vesicle. At last, the protein of the membrane should be transported to the cell membrane.Learn more about cell here: https://brainly.com/question/13250146

A. Genes from both parents are interchanged, which increases the number of possible combinations that the offspring can receive.
B. Chromosomes from both parents are interchanged, which increases the number of possible combinations that the offspring can receive.
C. Genes from both parents are kept separate, which reduces the number of possible combinations that the offspring can receive.
D. Chromosomes from both parents are kept separate, which reduces the number of possible combinations that the offspring can receive.

How do ultrasound waves clean jewellery
Answer:
They use ultrasound waves and chemicals combined to create bubbles that "cling" to the foreign particles such as dirt, oil, and unknown substances.
Explanation:
Ultrasonic cleaners are useful for jewelry cleaning and removing tarnish. They use ultrasound waves and chemicals combined to create bubbles that "cling" to the foreign particles such as dirt, oil, and unknown substances. The high frequency waves are sent out and pull the contaminants off the object.
Answer:
Ultrasound waves and chemicals are combined to create bubbles that "cling" to foreign particles such as dirt, oil or other unknown substances. The waves are sent out to extract these particles.

Which of the following describes what might happen with a sudden increase in precipitation in the grassland biome? (4 points)
a
Rise in drought-tolerant plants
b
Salt and sediment deposition
c
Increase in plant and animal diversity
d
Nutrient loss and soil erosion
Increase in plant and animal diversity describes what might happen with a sudden increase in precipitation in the grassland biome. Therefore, the correct option is C.
What is precipitation?Precipitation is the phenomenon in which condensed water vapors falls on the earth's surface under the influence of gravity.
A sudden increase in precipitation in the grassland biome can provide more water for plants and support their growth, which can lead to an increase in plant productivity and diversity. This in turn can provide more food and habitat for animals, leading to an increase in animal diversity as well.
While there may be some nutrient loss and soil erosion as a result of increased runoff, the overall effect on the ecosystem is typically positive in terms of increased biodiversity. Salt and sediment deposition are not typically associated with an increase in precipitation in the grassland biome. Therefore, the correct option is C.

What is an example of ionization?
A. vegetable oil dissolving in water
B. table sugar dissolving in water
C. table salt dissolving in water
D. hydrogen chloride dissolving in water
Answer:
well.. I apologize if I'm wrong but I think it'd be C because ionization is when something basically can go into water and loose part of its' substance to become apart of the water and salt pretty much dissolves completely in water lol

Density - Mass / Volume
Density - Mass / Weight
Density - Volume / Mass
Density = Volume / Weight
Answer: Density=Mass/Volume
Explanation:
Answer:
[tex]density = \frac{mass}{volume} [/tex]
explanation :
here some examples
the mass of 20 cm³ of mercury is 272g. calculate it density of mercury.
[tex]density \\ = \frac{mass}{volume} = \frac{272g}{ {20cm}^{3} } [/tex]

Do multicellular organisms GROW? Do multicellular organisms DEVELOP
Answer:
It has physically increased in size. Often, growth of a multicellular organism occurs as more cells are created. In unicellular organisms (like bacteria), growth still occurs. ... For this reason, most biologists will tell you that development only occurs in multicellular organisms, not in unicellular ones.
If plant has the same amount of sunlight but less water, then the process of glucose would A- increase, B-decrease, C- stay the same

Another students says that the earth’s magnetic poles have flipped many times in the past. How would you evaluate their statement?
Question 18 options:
This is a true statement.
This false because the magnetic field is fixed and cannot change.
This is false because a compass always points at the true North Pole.
This is false because the magnetic field has only flipped once.
Answer:
True
Explanation:
As a matter of geological record, the Earth's magnetic field has undergone numerous reversals of polarity. We can see this in the magnetic patterns found in volcanic rocks, especially those recovered from the ocean floors. In the last 10 million years, there have been, on average, 4 or 5 reversals per million years.
Photosynthesis produces chemical energy and Cellular Respiration uses chemical energy. What type of chemical energy do they both use?
A. protein
B. sunlight
C. food
D. glucose
Answer:
Photosynthesis uses energy from the sun in terms of sunlight and cellular respiration uses ATP energy.
Photosynthesis uses energy from the sun and cellular respiration uses glucose to get ATP energy. Thus option B and D are correct.
what are the factors affecting photosynthesis ?
The process in which autotrophic plants use light energy from sun and convert it into chemical energy, and prepare their food in the form of glucose called as photosynthesis.
This chemical energy is created from water and carbon dioxide and stored as a sugar molecule, it occur in chloroplasts which has three pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll.
various factors influence photosynthesis like increase in light intensity causes higher rate of photosynthesis, Higher concentration of carbon dioxide increases the rate of photosynthesis, Temperature range between 25° to 35° C optimum for photosynthesis,
Thus option B and D are correct.
