Answer:
These are just the answer key. You will have to fill in the lower half of the questions yourself. I did not consider 32% and 1.6% approximately the same but the answer key did.
Hope this helps:)
Explanation:
The box’s measurements are: length = 50 cm, width = 25 cm, and height = 25 cm. The measurements of the block are: length = 10 cm, width = 10 cm, and height is 5 cm.
Out of 100 marble drops or shots, the marble hit the block 32 times.
volume of the box = 50 × 25 × 25 = 31250 cm 3
volume of the block = 10 × 10 × 5 = 500 cm 3
Ratio = 500/31250 = 0.016 × 100 = 1.6%
The volume of the block is 1.6% of the volume of the box
Ratio = 32 hits/100 shots = 0.32 × 100 = 32%
The block was hit 32% of the time.
Percentages will be similar and both be small percentages

What two parts of a nucleotide do not change throughout the structure of DNA?
Answers
Answer:
The second portion of the nucleotide is the sugar. Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA.
Explanation:
thanks me and follow me
Five-carbon sugar (deoxyribose sugar) and phosphate moiety are the two parts of a nucleotide which do not change throughout the structure of DNA.
What are Nucleotides?Nucleotides are the organic molecules which are consisting of a nucleoside molecule and a phosphate moiety. They serve as the monomeric units of the nucleic acid polymers- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all the different life-forms on the Earth.
Nucleosides are made up of nitrogenous bases and pentose sugar. There are changes at the nitrogenous bases in the different nucleoside molecules however, there are no changes in the pentose sugar and the phosphate moiety of the molecule.

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
Answers
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.

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.
Answers
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.

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.

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.
Answers
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
