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

Which of the following changes demonstrates a chemical property? *
O A substance breaks in half
A substance combusts (burns)
O A hammer bounces off a substance
O A substance floats in water

Answer:
The correct answer is B. Combustion is a chemical change. When a substance is burned, it forms new substances. Therefore, combustibility is a chemical property because it can only be observed when a substance undergoes a chemical change.
Explanation:
Hope that helps!
Answer:
The answer would be "A substance combusts (burns)".
Explanation
All of the other options are basic physical changes that don't alter the substance on a molecular level, whereas burning a substance permanently changes the molecular makeup.
Imagine a glucose molecule entering the cell membrane. Would that
molecule be able to reach the mitochondria faster if the cell had a smaller
volume or a larger volume? Explain.
Answer: THE TRANSPORT OF A MOLECULE FROM THE CELL MEMBRANE TO THE MITOCHONDRIA WOULD BE FASTER IN A CELL WITH A SMALLER VOLUME BECAUSE THERE WOULD BE LESS DISTANCE TO TRAVEL

Glucose is a simple sugar that constitutes of carbon, hydrogen and oxygen atoms. It is the most abounding monosaccharide out of all the carbohydrates.
The glucose molecule will move actively to the mitochondria from the cell membrane if the membrane has a smaller volume.
The reason for the answer is:
Smaller the cell size less will be the covering space, hence the molecule will move less distance to reach its target.Mitochondria uses glucose molecules and generates carbon dioxide as the waste material.It is not always beneficial for the cell to be larger sometimes smaller cells can be more dynamic.Therefore, the glucose molecule will travel faster when the cell membrane has a small volume.

Why did life first occur in the oceans and not on Earth’s surface?
Answer:
I think because many more bacteria and cells and etc were first like created in the water, they they developed and made bigger and bigger living organisms
Answer:
Because God decided that he was gonna make animals first and he started with the ocean and then land and sky. He then made Adam to take care of all of the animals. But saw that he was lonely and made Eve with one of his ribs. He then put them in the garden of Eden with a tree that was forbidden to eat from. The tree of knowledge of the good and evil. One day eve was walking by the tree when a serpant asked her why they didn't eat from it. She replied by saying that God asked them to not eat from that tree. The serpant told Eve that God just doesn't want them to be knowledgeable like him. She took a bite of the apple and then gave some to Adam. They then realized that they were naked and made clothing from animal skin. This was what created sin. They tried to hide from God but he already knew and he banished them from the garden with angels and a fire sword at the enterance. He went to the serpant and cursed him for telling Eve to eat from the tree. Adam and Eve went on their way and had 2 boys. Cane and Abel.

A wildlife biologist and her team counted 150 lizards in a 25 km area. What is the population density
Given parameters:
Number of lizards = 150 lizards
Area of the study = 25km²
Unknown:
Population density = ?
Solution:
Population density refers to the number of organisms per area in a particular location.
Mathematically;
Population density = [tex]\frac{Total Population}{Area}[/tex]
Population density = [tex]\frac{150}{25}[/tex] = 6lizards/km²
The population density of the study area is 6lizards/km²
What is the difference between a species, a population,and a community
Answer:
A species is a group of organism that share genetic heritage and are Also able to interbreed.
Population can be defined as the total number of organism of the same specie living together in a habitat.
Community is made of all the population of living organisms that exist together in a habitat.

A seismograph station is located several thousand kilometers from an earthquake’s epicenter.
Explain the order that the S and P waves will arrive at the station.
By using the characteristics of the S and P waves explain why they arrive in the order they do.
Answer:
The P waves will arrive at the station first because they travel the fastest at an average of 6.1 km/s. The S waves will arrive second, traveling slower at approximately 4.1 km/s. The two different waves would have arrived 3 minutes apart, based on the S-P Wave Interval Chart.

Metalloids that can conduct electricity at high temperatures are
called
Metalloids that can conduct electricity at high temperatures are called semiconductors.
Semiconductors are a group of elements that have properties intermediate between those of metals and nonmetals. They have some characteristics of metals, such as being able to conduct electricity, but also some characteristics of nonmetals, such as having lower conductivity than metals.
At low temperatures, semiconductors have very low conductivity. However, at high temperatures, they can conduct electricity more effectively. This is because at higher temperatures, the thermal energy causes more electrons to break free from their atoms and become available for conduction.
One example of a semiconductor that can conduct electricity at high temperatures is silicon. Silicon is widely used in electronic devices, such as computer chips and solar cells, due to its ability to control and amplify electrical signals.
In summary, metalloids that can conduct electricity at high temperatures are known as semiconductors. They have properties intermediate between metals and nonmetals and can conduct electricity more effectively at high temperatures. Silicon is an example of a semiconductor commonly used in electronic devices.

Which of the following terms are used to indicate that cell membranes will allow only certain molecules to pass through without assistance?
A. Selective Permeability
B. Open Bilayer
C. Homeostatic Membrane
D. Temporary Permeability
The plasma membrane separates the cell from the outer environment. It only allows the movement of certain molecules through selective permeability. Thus, option A is correct.
What is selective permeability?Selective permeability is the property that allows the movement and transportation of the molecules inside the cell through active or passive transportation.
It is seen in the plasma or the cell membrane of the cell as it allows only certain specific molecules to enter or leave the cell. It is important for the protection of the cell.
This allows the exchange of the nutrients and waste produced in and out of the cell. The selective permeability is the semi-permeability that is due to the lipid bilayer of the membrane.
Therefore, option A. the cell membranes are selectively permeable.
