Explanation:
covelant bonding occurs when pairs of electrons are shared by atoms.
Southwards parallel to the shoreline.
A geological course that is made up of the movement of sediments like silt, clay, shingle and sandd within a coast parallel to the shoreline, which is reliant on oblique approaching wind direction is called longshore drift. Oblique incoming wind restraints water along the coast, and so creates a water current which moves parallel to the coast.
Answer:
The way I would separate the shell fragments from the sand would be by using a filter. As shell fragments are larger than sand. So I would use a filter with 2 mm spaces to separate them. Now, for the sand separation from the water, I would heat the water so it would evaporate and connect a tube to another recipient making the sand stay in the first tube and the water vapor cools in the tube to precipitate in the other recipient. Three mixtures I have prepared at home are chocolate milk, coffee and cream, and lemon juice and tea.
Explanation:
To understand this answer we have to remember a few things. First, mixtures always have solute and solvent. The solvent is the most liquid component of the mixture and it can incorporate the more solid element in its composition to carry it. Now, there are several methods to separate them, barrier methods like filters are the first and more basic ones, as they are aimed to separated big solutes. While evaporation can be used to separate two very liquid elements. Like distillation of alcohol to separate the most concentrated oil from the alcohol.
Since the country has a smaller area and a large amount of people (although smaller than Australia) the ratio of land to people in New Zealand is much larger than the ration of land to people in Australia.
Answer;
C. A wall of stones and mortar
This would act as a model describing the cell membrane.
Explanation;
A cell membrane is made up of a phospholipid bilayer with embedded proteins.
A cell membrane hold the different components of the cell together and to protect it from the environment outside the cell. It acts as a boundary between the inside environment and the outside environment of a cell.
It regulates the materials that enters and exits the cell; through selective movement of substances in and out of the cell.
