Answer:

The inside is becoming positive.

Explanation:

The membrane potential may be defined as the difference in the electric potential between the outside and inside of the cell. This potential difference is important for the conduction of nerve impulse.

The depolarization of the cell occur due to the movement of sodium ions inside the cell. The depolarization of the cell changes the membrane potential from -70mV to +30mV. The inside of the cell become more positive than outside of the cell.

Thus, the correct answer is option (a).

Deciding between recycling of conventional plastics and developing biodegradable plastics is a complex issue because:___________

Julli [10]

Answer:

Conventional plastics-

"Plastics are typically organic polymers of high molecular mass, but they often contain other substances."

Composition-

"Oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse due to being complex composites having varying levels of contamination.

Biodegradable plastics-

"They are largely manufactured from renewable natural resources, to produce biodegradable materials with similar functionality to that of oil-based polymers."

Explanation:

Complex Issue-

Diversity of biodegradable materials and their varying properties makes it difficult to make simple, generic assessments such as biodegradable products are all ‘good’ or petrochemical-based products are all ‘bad’.

Biodegradable packaging materials are most suitable for single-use disposable applications where the post-consumer waste can be locally composted.

klio [65]

Answer:

The rectus abdominis muscle is the muscle that is located at the front of the abdomen; it is most often referred to as the ''abs.'' The action of this muscle pulls the rib cage and the pelvic bone towards the middle of the abdomen, just like the movement when a person performs a sit-up or crunch.
