explain how the structure of a cell´s membrane is related to its function.
Answer:
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
The structure of cell membrane helps in being selectively permeable that play a major role in regulating the entry and exit of molecules into and out of the cell.
The cell membrane is a biological membrane that makes the barrier between the interior of all cells and the outside environment. It is composed of a phospholipid bilayer with embedded proteins.
Due to phospholipid bilayer that has hydrophilic heads toward outside and intercellular matrix and hydrophobic tails in the middle, it is selectively permeable to ions and organic molecules:
It forms a physical barrier between the cell and the external environmentselected necessary molecules to pass through itregulates the entry and exit of molecules into and out of the cell. permits the entry of vital molecules like water, oxygen and amino acids, glucose into the cellthese molecules are crucial for various life processesmetabolic waste products are expelled through the cell membrane.it provides signals from one cell to another.Thus, the major function of cell membrane is due to its structure.

Explain how surface mining affects plant life
Answer:
Surface mining destroys all plant life in the area the mine occupies. Plants living in the area where the surface mine is to be located are removed. ... All three types of mines cause some damage to the environment.
Explanation:
IF THIS HELPS MARK AS BRAINLIST
Surface mining destroys vegetation and affects soil strata. Mining disrupts to topsoil microorganisms. Reclamation operations that dilute topsoil with subsoils can degrade soil.
What is surface mining?Surface mining is a type of mining in which the soil and rock covering the mineral deposits are removed. It's the other way to mine underground. The rock on top is left in place, and the needed minerals are taken out through shafts or tunnels.
Surface mining can hurt fish and aquatic resources by causing erosion and sedimentation, drying up wetlands, rerouting and channelizing streams, and putting toxic chemicals into the surface water and aquifers.
This will further disrupt plant life on surface.

How do ocean currents affect weather in areas close to shore?
Answer:
Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region.

When a molecule other than water moves from an area of high concentration to an
area of low concentration with the use of a protein it is an example of what type of
passive transport.
Osmosis
Facilitated diffusion
Active Transport
Diffusion
Answer:
Osmosis
Explanation:
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
This direction is from high concentration to low concentration, this will create equilibrium.

how many chromosomes are represented by these eight strings of beads shown in the picture?
Answer:
4
Explanation:
1. Which of the following is a characteristic associated with an organism's niche but not with its habitat?
a. climate
b. soil quality
c. place in the food web
d. location within the ecosystem
A characteristic that is associated with an organism's niche but not with its habitat is the place in the food web. Thus, the correct option for this question is C.
What is Habitat?Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In a more simple sense, habitat may also be characterized as an area where the basic demands of an organism are fulfilled like food, space, and mating partner.
According to the context of this question, a pace in the food web determines the position and the type of food that an organism naturally eat or consume. As it connects the organisms with the source of energy.
But in reality, it does not describe any characteristics of the habitat to which a particular organism belongs. This is because the food web is the pictorial representation of organisms on the basis of their food habit and nature.
Therefore, a characteristic that is associated with an organism's niche but not with its habitat is the place in the food web. Thus, the correct option for this question is C.

Explain how bacteria become resistance to
antibiotics, supporting Darwin's theory..
Answer:
They adapt over time to the antibiotics.
Explanation:
Because of Darwin's theory of natural selection, the bacteria that are resistant to antibiotics will multiply whereas the ones that don't survive will die off. Over time, the species will only consist of those bacteria that are resistant, because they are the ones that survived. Hope this helps!
Answer:
Since bacteria reproduce at a very fast rate, they can also develop mutations; creating new strains. Some bacteria might become resistant to certain antibiotics because of these mutations. The evolution of the bacteria supports Darwin's theory of evolution !

Which description identifies a factor that influences the flow of water through the plasma membrane of a human cell?
A. The size of the phospholipids and proteins composing the plasma membrane
B.the concentration of solutes on either side of the plasma membrane
C.the presence or absence of a cell wall outside the plasma membrane
D.the number of contractile vacuoles on the surface of the plasma membrane
Answer:
A
Explanation:
Osmosis refers to the movement of water molecules across a selectively permeable membrane. During this process, water molecules move from an area of high concentration to an area of lower concentration.
A factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).Osmosis is a type of passive transport mechanism that does not require energy to occur.During osmosis, water diffuses through a selectively permeable membrane from an area of high water concentration to an area of lower water concentration.In an isotonic cell, the concentration of solutes and water molecules is equal on both sides of the plasma membrane.In conclusion, a factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).
