The difference between Prokaryotic cell and Eukaryotic cell are;
[tex]\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or} & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \ membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}[/tex]
Explanation:
Prokaryotic cells
The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells
Eukaryotic cells
Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell

Besides the interaction between animals and plants, what other factors may be involved in the carbon and oxygen cycles?
Answer: .co2
Explanation: co2
The other factors which are involved in the carbon and oxygen cycles are air, ground, respiration, and photosynthesis.
Which factor contributes to the carbon cycle?
Explanation: Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
How do plants and animals interact with the carbon cycle differently from one another?Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood, and leaves decay bringing the carbon into the ground.

What is an example of the strong force in action
Answer:
A magnet keeps a cabinet door closed. The Sun pulls on Earth as Earth moves around the Sun. The protons in the nucleus of a carbon atom are held together.So this is an example of the strong force in action.
There are 4 fundamental types of forces:
1. Electromagnetic
2. Gravitational
3. Strong
4. Weak
You asked about strong force, the strong force keeps quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons.
During the Cardiovascular Function Labster simulation, cardiac output did not increase as much as oxygen consumption rate (which increased 8x), what is the most likely mechanism that could allow increased oxygen delivery by the cardiovascular system
Answer:
An increase in the rate of oxygen that has been removed from hemoglobin could increase the supply of oxygen by the cardiovascular system.
Explanation:
Hemoglobin is a protein, present in the cardiovascular system, whose main function is to remove oxygen from the lungs and take it to the tissues of the human body. Therefore, the more oxygen is removed from the hemoglobin, the greater the oxygen supply. This applies even in the situation presented in the question above, where cardiac output did not increase in the same way as oxygen consumption. In this case, if oxygen consumption is high, the removal of oxygen from the hemoglobin must be increased to supply this consumption.

PLS HELP BIG GRADE 5. Water stored in a reservoir is used to generate electricity as it flows down and into a river. The river flows to the ocean, where it evaporates to form clouds. Rain falls from the clouds into streams that flow into the reservoir.
Which location of the water has most potential energy? Assume the amount of water in each place is the same. These are the locations: 1. where it enters the river from the reservoir, 2. when it is in the ocean, 3. when it is in the reservoir, and 4. when it is in the clouds.
1. Where it enters the river from the reservoir.
2. When it is in the ocean.
3. When it is in the reservoir.
4. When it is in the clouds.
Explain your answer.
Answer: Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.
Explanation: Hydroelectricity can be defined as the generation of electricity by utilizing the speed of water stream in a reservoir of water. The high speed water current is used to move the water turbine the energy produced in the turbine can be used to generate electricity by the generator.

The parachute was invented 4,000 years ago, when Chinese observers noticed that air resistance slowed free-falls. Legend states that a safe jump was made from a granary using two bamboo hats. In the 800s, Abbas Ibn "Armen" Firnas jumped off a tower in Cordova (Iberian peninsula) using a large cloak like a wing.
2. Give one possible reason why the population decreased in 1990 after it had reached its
carrying capacity
1 I
Answer: The population exceeded its carrying capacity because there were more resources available so many deer reproduced and the population quickly exceeded the carrying capacity.
Explanation:
When the population size exceeds the carrying capacity, the population must decrease. One possible reason is the lack of available resources to support this population size.
What is Carrying Capacity?
A growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
The population growth per capita rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Carrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
If the population size, N, is inferior to K ⇒ the population still grow. When N approximates to K ⇒ the population's growth speed decreases. When N=K ⇒ the population reaches equilibrium, When N is superior to K (N>K) ⇒ the population must decrease in size because there are not enough resources to maintain that size.So when the population size exceeds K, carrying capacity makes the population decrease in size. This is because there are not enough resources for this population to survive.
Probably this population's size exceeded the carrying capacity because there were available resources and animals were not predated by any other species. So this population kept growing until they exceeded the carrying capacity level.
Once they did it, the environment could not support this population size, probably because of the lack of available resources, so the population had to decrease in size. Mortality rate must have increased while natality rate must have decreased.
One possible reason is the lack of available resources to sopport this population size.
