Which of the following would likely move through the phospholipids of the
cell membrane most easily? *

CO2

Glucose

K+

Starch

Answer:

CO2

Explanation:

Oxygen and CO2 can move through the cell membrane through simple diffusion because they are small molecules.

It's possible that CO2 travels through the lipid bilayer far more quickly than any other molecule. Therefore, option (A) is correct.

According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Therefore, small and simple molecules like water, H2O , CO2 can pass through the cell membrane easily as it is partially permeable.

Suppose an individual giraffe could not reach high leaves on a tree
its neck was too short. Lamarck's theory would suggest that the giraffe could
undergo physical changes that would lengthen its neck simply by stretching
to reach the branches. What experimental result would disprove this?
E The necks of giraffes today are shorter than the necks of early giraffes.
G. Giraffes with longer necks prefer to eat leaves from higher branches.
H. Neck lengtı does not change when giraffes are fed branches at different
heights.
1. Giraffes with longer necks frequently produce offspring that also have
longer necks.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.

Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
