Answer:

A thin, flexible, semipermeable barrier around the cell which regulates what enters and leaves the cell is cell membrane. The plasma membrane is another name of the cell membrane.

The plasma membrane is semipermeable because it allow only some molecules to enter and exit the cell. Small polar molecules can easily cross the plasma membrane along the concentration gradient diffusion.

For the passage of large, non-polar and charge molecules plasma membrane have carrier proteins which can be used to transport the molecules along the concentration gradient by facilitated diffusion or against the concentration gradient by active transport. Therefore, the correct answer is the cell membrane.

1. How does the inner core affect all of the Earth's other layers?

Artist 52 [7]

Answer:

With the heavy inner core, the earth's orbit and rotation will remain stable over the long term, giving us day and night and summer and winter. ... These swirling convection currents result in the earth's magnetic field which keeps us properly oriented for travel, and shields earth from deadly cosmic rays

Explanation:

The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.

What do phenotype and genotype have in common?

N76 [4]

They can both be used to identify organisms. Also, the phenotype of an organism is different depending on the genotype of the organism, making them relate to one another.

Hope this helps. Good luck! :)

How does the standardized taxonomic system provide a solution to the problem of communication between scientists who speak diffe

Nastasia [14]

Answer:

The Taxonomic Classification System provides a universal language to identify and classify species

Explanation:

The Taxonomic Classification System is a model that places all forms of life into hierarchical categories. These categories are organized in the following order: domain (i.e., Bacteria, Archaea, and Eukarya), kingdom (i.e., Archaea/Archaebacteria, Bacteria/Eubacteria, Protista, Fungi, Animalia, Plantae, ), phylum, class, order, family, genus, and species. The Taxonomic Classification System can be used to easily recognize a particular organism/species only by its genus and species name, which is known as binomial nomenclature.
