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.

This is an active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.
faltersainse [42]

Answer:

Primary active transport

Explanation:

Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump  is an example  of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).

Answer:

Students who take a PE class and who will be eating sugary snacks before PE.

Explanation:

The control variable (or control group) is an experimental element which is constant or unchanged throughout the course of the experiment.

The option "students who take PE class and who will be eating sugary snacks before PE" will remain unchanged and constant because the whole point of the experiment is to see the effects on students performance in PE after eating sugary snacks.

Hope this helps :)
