Mollusks
Mollusks is the group of invertebrates that made up the majority of the Marine species. Their bodies tend to not divided into segments like other organisms.
Answer:
A. What causes some people to be color-blind?
Explanation:
This is something that could be tested with different variables including DNA, or past family medical history.
Species with more likely homologous structures share a common ancestor.
- D. share a common ancestor.
<h3>What are example homologous structures?</h3>
The most correct definition for homology would be: They are structures of individuals, of different species or not, that were inherited from a common ancestor. The human arm is homologous to the horse's front leg. The bat's wing is homologous to the whale fin.
With this information, we can conclude that homologous have same embryological origin of structures from different organisms, and these structures may or may not have the same function

Answer:
Sometimes molecules cannot move through the cell membrane on their own. These molecules need special transport proteins to help them move across the membrane. Facilitated diffusion is the diffusion of substances with the help of transport proteins in the plasma membrane. These special proteins are called channel proteins or carrier proteins, and they are attached to the cell membrane. In fact, they go through the cell membrane, from the inside of the cell to the outside. Facilitated diffusion is used for molecules that cannot diffuse rapidly through cell membranes on their own, even when the molecules are moving from high to low concentration areas. An example is the sugar plants and animals use for energy, called glucose. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient so it does not require the use of cellular energy.
