What are two biotic factors and two abiotic factors in the photo below.
In the tundra, what is the difference between the biotic and abiotic factors you saw in the image?
How do the biotic and abiotic factors you chose interact?
Answer:
the 2 biotic factors are the plants in the corner and the 2 reindeer
The 2 abiotic factors in the image are the water and the mountains
The difference between the biotic and abiotic factors is that the biotic factors are living and the abiotic factors aren't living things.
The water gives nutrients to the reindeer.
Explanation:
Biotic factor are living things Abiotic factor are non-living things (;
Muscle cells contract using ATP. There is little ATP in your blood stream. How do your muscle cells get ATP they need to contract and move you?
Answer: Aerobic ATP Production
Explanation: During everyday activities and light exercise, the mitochondria of muscle fibers produce ATP in a process called aerobic respiration. Aerobic respiration requires the presence of oxygen to break down food energy (usually glucose and fat) to generate ATP for muscle contractions

You are working in a lab trying to identify a new organism. It looks like a plant, but it could be a fungus. Which of the following tests would NOT be useful in determining which it is?
A. Testing to see if part of the organism grows underground
B. Testing it for Chloroplasts
C. Testing it to see if it absorbs food from the soil
D. Testing it for Chitin
Testing to see if part of the organism grows underground would not be useful in determining whether it is a plant or a fungus.
How other tests would help in determining the organism?Testing it for chloroplastsPlant and green algal cells have a structure called a chloroplast, which is where photosynthesis takes place.A plastid is a sort of body that is formed like a disk, an oval, or a circle and is used to synthesize and store food. Chloroplasts are one type of plastids. The green color of chloroplasts sets them apart from other types of plastids.If the given organism shows a positive test for chloroplast then it is a plant otherwise fungus.Testing to see if it absorbs food from the soilAlmost the majority of the water and nutrients consumed by terrestrial plants are taken up by their roots from the soil.Therefore if the given organism absorbs nutrients from the soil then it is a plant.Testing it for ChitinMost fungi, contain chitin. Alpha-chitin makes up the majority of these fungi's cell walls.If the given organism shows a positive test for chitin then it is a fungus.

how are babies produced specifically?
Answer:
Babies are made when special cells called sperm (produced by men) combine with cells called eggs (produced by women) in a process called conception. Each of these cells is produced by a process called meiosis which makes cells containing half the information of the parent.

Which part of the plant and animal cells in the animals does cellular respiration take place
cellular respiration in eukaryotic cells takes place in the mitochondria. Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP.
The ability of water to act as a solvent for so many substances is due to its _______.
Answer:
The ability of water to act as a solvent for so many substances is due to its structure, it can dissolve many ionic and polar molecules
Explanation:
polar nature Water's tendency to share electrons unequally makes it a polar molecule. The slight charge on either side of the water molecule allows it to bond (create a solution) with any atom with a positive or negative charge.

Which of the following examples of membrane transport requires energy from ATP?
a. Movement of Nations from a lower concentration inside the cell to a higher concentration outside of the cell
b. Movement of glucose molecules from a higher concentration outside of the cell to a lower concentration inside of the cell
c. Movement of water into a cell
d. None of the above
Answer:
Active transport uses energy to transport molecules across the plasma membrane. This uses energy from ATP. They also use pumps to get molecules in or out of the cell. Passive Transport does NOT use energy to transport molecules across the membrane.

A runner has a speed of 25 m/s. They see the finish line and speed up to 30 m/s. This happens in 5 seconds. If the runner has a mass of 75 kg, with what force did the runner cross the finish line? Show all work to receive full credit.
I know the answer is 75N but I don't know how to get 75N
Given parameters:
Initial velocity = 25m/s
Final velocity = 30m/s
Time = 5m/s
Mass of runner = 75kg
Unknown:
Force to finish the race = ?
Solution:
Force is defined as a pull or push on a body. According to Newton's first law, we can mathematically express force as the product of mass and acceleration;
Force = mass x acceleration
But we know that acceleration is the change in velocity with time, so;
Acceleration = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
So, force;
Force = mass x [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
Input the parameters and solve;
Force = 75 x [tex]\frac{30 -25}{5}[/tex] = 75N
The runner crosses the line with a force of 75N

Which value is most likely to be the pH of a salt that is formed by the reaction of a weak acid and a strong base?
2.0
6.8
7.0
8.7
Answer:
8.7 (D)
Explanation:
A weak acid (anything below 7 on a PH scale) and a strong base (anything above 7 on a PH scale). The strong base will counter act the weak acid and dominate it meaning the answer will be above 7 giving you 8.7
The correct answer is 8.7
What is pH?
pH is the measure of the acidity and basicity of a solution.
The pH scale usually ranges between 0-14 pH less than 7 are strong base pH more than 7 are weak acidsWhy other option are incorrect?From the given options the Option 8.7 is the value which is greater than 7 is a strong base Hence 8.7 is correct and others are incorrect.

In which column on the chart below would the information below best fit for a mode of reproduction, CANNOT REPRODUCE WITHOUT A HOST?
Answer:
B. Virus.
Explanation:
Hello.
In this case, since bacteria (A.) reproduce via asexual reproduction via mitosis and the animal (D.) and vegetal (C.) cells could reproduce via sexual or asexual reproduction depending on the organism, they do not need a host to start the replication of the DNA and therefore reproduce. In such a way, it is widely known that viruses need a host that facilitates the replication of their DNA or RNA (depending on the virus) since they only have their genetic information but they do not have neither the RNA nor the DNA polymerase that favor such process, that is why they need a host.

how does density affect refraction?
Answer:
Density of any substance or medium determine the amount of light that will be refracted.
Explanation:
Density of any substance or medium determine the amount of light that will be refracted.
The higher is the density of any medium, the higher will be the number of atom or molecules in a given medium and hence more obstruction will be produced for light. High density also causes high refractive index.
The light usually bends away from the normal when light travels from a region of low to high density and light bends towards the normal when light travels from a region of high to low density
1. Identify the layer of the atmosphere that is constantly being hit by photons, has very low pressure, and temperatures that decrease from 120° Celsius to -80° Celsius as you move down through the layer.
Answer:
Mesosphere
Explanation:
The Mesosphere is a layer of the atmosphere that is above the Stratosphere and below the Thermosphere. This is the third layer of the atmosphere. Some of its characteristics include;
1. It is constantly being hit by photons: These photons are in the form of meteors that constantly hit this layer of the atmosphere. Meteors which are particles of dust release light energy that makes them visible to the human eyes as shooting stars.
2. The layer is characterized by very low pressure. This makes the air here thin and as the altitude increases, the air becomes very cold.
3. Temperatures decrease from 120° Celsius to -80° Celsius as you move down through the layer: The temperature in this layer decreases as the altitude increases.
