Answer:

d. Their gene sequence is less well conserved than their structure.

Explanation:

The fundamental definition of a protein family is that they need to be homologous or share strong sequence identity/similarity.

Whereas a protein superfamily encompasses proteins that may not be homologous but share similarities in their structures.

antiseptic1488 [7]

Answer:

In winter, the forest is extremely cold. The roots of the evergreen plants are unable to access water. The needle-like structure of these trees minimizes water loss from transpiration. The needles are also dark in color. The color allows them to absorb maximum sunlight for photosynthesis. Even with little food, the animals in the biome can access food from these trees. Squirrels can eat the seeds from the pinecones. Crossbill birds have special beaks that allow them to access the seeds. Moose eat sappy twigs. They’ve also adapted to build fat reserves to help them survive the harsh winter. Some animals hibernate, and others migrate to warmer places to survive the winter. During summer, the long days allow abundant photosynthesis. So, there’s increased plant growth accompanied by increased insect activity. Trees with seasonal leaves develop new leaves. Birds that had migrated return during the summer, when food is readily available. The plants and animals work as a system to obtain an adequate food supply throughout the year.

What are some reasons why common names are insufficient for naming animals? answer in a short paragraph form and include at leas
lana66690 [7]

Answer:

Scientific names of animals use both the genus and species name, which is much more specific than common names, and gives more information.

For example, using the name cat just tells us that the animal is a cat

however, the scientific name felis catus, tells us that the species is catus and the genus is felis
