Answer:
Its D, The cell membrane(also known a the plasma membrane) has a job in which it has to allow passage in and out of the cell. Therefore it can prevent harmful substances from entering the cell. Think of it as security, either allowing you access or denying you depending on if you're a threat
Food chains model energy flow through an ecosystem. Producers pump energy into an ecosystem from an environmental source, and this energy is then passed from one organism to the next.
Answer:
1. Jetty: Hard structure Built Perpendicular to the Shore, Can cause sand build-up on up drift side of the structure
2. Beach Nourishment: Brings in more sand to replace erosion.
3. Seawall: Hard structure that also provides flood protection, Prevents erosion by directing waves back to the ocean
Explanation:
Jetty is a hard and long structure that constructs of wood or concrete near the coastline, perpendicular to the shore that protects it from tides and currents which helps in preventing erosion. It can lead to build-up of sand on updrift side.
Beach nourishment is the process that replaces the sand or land that lost due to erosion and relensihsh the infrastructure of the coastline and protects the people and beach.
Seawall is also a hard provides protection from erosion by preventing the flood and pushes back the currents and tides to the ocean.
Answer:
2.94 × 10²⁰ N/C
Explanation:
Given that:
The nucleus of "Lead-208 has 82 protons,
with a radius (r) 6.34×10-15 m, &
each electric charge has a value of 1.60218 × 10^-19 C
∴ The formula for calculating an electrical field at the surface of the nucleus is:
Substituting our values into the equation above, we have;
E =
E = 2.93870499×10²⁰ N/C
E ≅ 2.94 × 10²⁰ N/C
Answer:
The answer however is yes you can, but you would probably die. The body mechanism for crying under water works just as fine above as below the water. So you can cry tears, they would just be mixed with the rest of the water.
