Answer:
I wasn't sure what you were asking
Explanation:
The fluid mosaic model explains various observations regarding the structure of functional cell membranes. According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.
a 4.24 kg marble slab has a volume of 1564 cm^3. what is it's density in g/cm^3? give you answer to the nearest tenth
Thhe density of the marble, given the data from the question is 2.7 g/cm³
What is density?The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can obtain the density of the marble. Details below
How to determine the density of the marbleThe following data were obtained from the question:
Mass of marble = 4.24 Kg = 4.24 × 1000 = 4240 gVolume of marble = 1564 cm³Density of marble =?The density of the marble can be obtained as follow:
Density = mass / volume
Density of marble = 4240 / 1564
Density of marble = 2.7 g/cm³
Thus, the density of the marble is 2.7 g/cm³

Answer: D
Explanation:
c) In dense rainforest, plants that grow close to the forest floor tend to have lower rates of photosynthesis than the very tall trees. Suggest why this might be.
Answer:
The reason why plants that grow close to the forest floor tend to have lower rates of photosynthesis is because sunlight is a vital component in the production of glucose. Using logic, you can see that the tree cause larger shadows to form—blocking sunlight.

Explanation:
describe the motion of the particles
of a liquid when heat added.
Answer:
Hope this helps!
Explanation:
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
Answer:
The liquid turns into a gas and the particles move around freely and fast.

Sample Response: Federalists believed in a strong central government. They argued in favor of separation of powers: the division of the government into three separate branches whose powers balance each other. They felt this would be necessary and helpful. On the other hand, Anti-Federalists were fearful that the separation of powers would not equally balance power. They did not believe that this separation could occur in a fair way.
Answer:
This represents a conflict Federalist vs antiferalists
Explanation:
Federalists and anti-federalists were two groups formed during the conventions to decide how the country would be governed and to decide the nation's legislative body through the federal constitution.
The federalists were represented by John Adams, Alexander Hamilton and George Washington who preached the need to establish a central government divided into three spheres that complemented and acted on different elements. The anti-federalists, on the other hand, led by Patrick Henry, believed that federalism gave the president too much power, allowing him to act like a king and that he could abuse power, in addition to exploiting the nation.
The ideological differences of these two groups led to many discussions and conflicts, but it ended with the adoption of federalism in the country.
Top predators are often keystone species in their habitat. Explain what happens to the biodiversity of an ecosystem when a top predator is deliberately removed from the ecosystem in which it lives.
Answer:
The ecosystem will fall out of balance.
Explanation:
The ecosystem will fall out of balance because once you remove the top predator, the plant eaters will grow in numbers, they will eat all of the vegetation, and will either need to adapt or die. Predators are very important, as is everything in the food chain

Organisms become extinct for many reasons. All BUT one is reason for extinction. That is
A) adaptations.
B) over-hunting.
C) climate change.
D) habitat destruction.
Answer:
A) Adaptations
Explanation:
If a species learns to adapt to their environment, then they will not become extinct
Answer:
adaptation
Explanation:
When a organism adapts to its surroundings it docent become extinct instead it survives. It wouldn't make sense that if it were to adapt then it would be extinct. While over hunting is a cause of extinction and so is climate change if the organism is not well adjusted to any temperature. Habitat destruction is also a cause of extinction because it kills the organisms home causing them to not have anywhere to live. So adaptation is the correct answer.

If you have had chicken pox once, you are not likely to get it again. What could be the reason for this?
Explanation:
Our blood will have antibodies specific to the chicken pox antigen.
Answer:
You may not get chickenpox twice, but VZV could make you sick twice. Once you've had chickenpox, the virus remains inactive in your nerve tissue. Although it's unlikely you will get chickenpox again, the virus may reactivate later in life and cause a related condition called shingles.
