The calcium ion passes easily through the membrane of one cell but
cannot cross the membrane of a second cell. Which part of the plasma
membrane allows this substance to cross? *
- Phosphate groups of the phospholipid bilayer allow the ions to cross.
- The fatty acid tails of the phospholipids allow the ions to cross.
- Protein channels in the plasma membrane allow the ions to cross.
- Carbohydrate groups on the membrane allow the ions to cross.
Answer:
Protein channels in the plasma membrane allow the ions to cross.
Protein channels which are present in the plasma membrane of the cell allow the ions to cross the plasma membrane. Thus, the correct option is C.
Channel protein is a kind of protein which is found embedded in the plasma membrane of the cell. Channel proteins function similar to a pore and it allows the diffusion of small ions and water molecules through them. Channel proteins are lipoproteins and these are synthesized in the rough endoplasmic reticulum of the cell near the nucleus.
Ion channels are the transmembrane proteins whose canonical function is the transport of ions and molecules across the plasma membrane to regulate cell membrane potential and also play an essential role in neural communication, nerve conduction, and muscle contraction in the body.
Therefore, the correct option is C.

The fossils came from the same organism.
The fossils are from an ancestor of animal T.
The fossils are from animals that lived at the same time.
The fossils are from a descendant of animal T.
2. Why do organisms evolve?(1 point)
Organisms naturally select traits that help them survive and reproduce.
Organisms with traits that help them survive and reproduce in their environment pass on those traits.
Changes in the environment cause organisms to change.
Organisms make changes to help them survive and reproduce in their environment.
3. Scientists examine fossils from three different animals. They determine that all three animals share similar structures and record their observations as follows:
Animal A and animal B have somewhat similar structures.
Animal A and animal C have very similar structures.
Animal B and animal C have very similar structures.
The scientists use the similarities to determine the order in which the fossils should appear in the fossil record. Based on the scientists’ observations, which order is the most reasonable?
