Answer: Option A Idea model
Explanation:
The plasma membrane has a double layer of phospholipids with proteins dispersed throughout these layers. These proteins perform several functions, including molecule transport, enzymatic functions, and signal transduction pathways.
The plasma membrane of cells has a structure commonly referred to as a lipid bilayer. This bilayer consists of two layers of phospholipids. Each layer with one hydrophobic (water-fearing) end and one hydrophilic (water-loving) end. These form a double layer as the hydrophobic ends of each layer face towards each other, while the hydrophilic ends face outwards towards the aqueous environments inside and outside the cell. Proteins are dispersed throughout this lipid bilayer. These proteins serve various functions such as acting as channels or carriers for the transportation of molecules across the membrane, acting as enzymes, or functioning in signal transduction pathways or cell adhesion.

It may be due to the fact that there was an event that eliminated many of the individuals in species.
The term genetic variation refers to the occurence of organisms in a specie that are composed of different genotypes.
If the genetic variation in a population at the yellowstone park is decreased it may be due to the fact that there was an event that eliminated many of the individuals in species.

Answer: The answer is C It will move away from the second magnet because like poles repel.
Explanation: Like poles retract
Answer:
Short answer-False
Explanation:
A concentration gradient is the difference between
two concentrations
Active transport allows cells to transport molecules
against a concentration gradient
Diffusion results in a net overall movement from a low
concentration to a high concentration
In diffusion particles are moving around randomly in
all directions
Osmosis requires energy from respiration to be carried
out
Partially permeable membranes allow any molecules
to pass through them
Explanation:
a) True. The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse.
b) True. Active transport requires cellular energy to achieve this.
c) False. Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration.
d) True. For diffusion to work, the particles must be able to move around.
e) True. Osmosis requires energy from respiration to be carried
out.
f) False. Partially permeable membranes allow only water but not other dissolved substances to pass through.
Answer:
the animal will consume food and inhale oxygen and drink water. the cell will use the oxygen and water to break down the glucose to form energy or ATP
