Some body please help me
Answer:
D. Lipids
Explanation:
A lipid is any of various organic compounds that are insoluble in water. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.
Lipids are an efficient source of energy (9kcal per gram) that the body stores in relative abundance. They also play an important role as building blocks for cell membranes, hormones, and physiologically active substances.

The beginning of the Cambrian period marks an important event in animal evolution - the appearance of organisms with ________.
Answer:
The beginning of the Cambrian Period is marked by the evolution of hard body parts such as calcium carbonate shells. These body parts fossilize more easily than soft tissues, and thus the fossil record becomes much more complete after their appearance.
explain how genetic engineering of plants and animals can be both beneficial harmful to the environment and to people.
Answer:
Genetic engineering of both plants and animals can cause food to be more abundant and can restore nitrites to soil in the case of plants and animals can create more stable environments by eradicating invasive species, however, there are concerns about improperly modified crops causing cancer in humans, they may overtake the genetically "pure" crops in the area, and animals have the concern of ethics and cancer.
Explanation:
Genetic engineering is generally seen as the future of food. It can serve as a cure for world hunger, causing enough food to be produced in a small enough space to provide for most of the world and causing plants to adapt to inhospitable growing conditions, however, there are concerns. For one, when genetically modifying animals, there may be the concern of how much body mass you can ethically put on an animal before it becomes torturous. You also have to worry about animals genetically processed to produce more meat developing cancerous growths due to their predisposition to gain more mass quickly, however this can be remedied. Animals, on the positive end, can be designed to feed off of invasive, harmful species. Plants may overtake their genetically "pure" cousins, however that is not necessarily a bad thing, as plants are equipped to evolve anyway, and it's quite possible you're just giving the plants a head-start.

Gated ion channels for sodium and potassium open and close in rapid succession, causing the neuron to depolarize and then return to its normal resting level, during each:
Given what we know, we can confirm that this process happens in between each action potential.
What is an action potential?The action potential is the rapid polarization and depolarization of cells and cell membranes when they receive an impulse. In this case, the action potential is used to open and close the gated ion channels for sodium and potassium.
Therefore, we can confirm that gated ion channels for sodium and potassium open and close in rapid succession, causing the neuron to depolarize and then return to its normal resting level, during each action potential.
