Homework Answers
Kelp attach themselves to rocks by means of a structure called holdfast.
Kelps are large brown seaweed that typically has a long, tough stalk with broad frond divided into strips. Despite its appearance, kelp is not a plant; it is a heterokont. Kelp grows in "underwater forests" in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago.
At the bottom of the kelp there are "roots"of the kelp known as holdfast . This root like structure enables the kelp to attach itself to a rock. At the holdfast, animals like sea urchins, brittle stars, sea stars, and sponges thrive. These holdfasts hold the kelp firmly attached to rocks, so that even when currents are at their strongest, kelp is no danger of being swept away.

Project managers have a tendency to want to carry the load themselves, even if it means working sixty hours a week. You were told to do everything within your normal working day. But, as a potentially good project manager, you probabll have the natural tendency of wanting to postpone some work until a later date so that you can do it yourself. Doing the activities, when they occur, even through transmittal or delegation, is probably the best policy. You might...

USING MATLAB...Write a function that creates a structure variable called createSpacecraft. The function should take four inputs, a number called mass (in kg), a number called fuel (in joules of energy), a number called orbit (in meters), and a number called engine (in newtons). It should return an output structure called spacecraft containing each of those values. Please ensure that both the function name, AND the names of variables within the spacecraft structure are exactly as instructed
