According to the idea that there is a limited amount of energy available in the body, what are considered to be the major physiologic processes wher an individual is in energy balance: O reproduction, cellular maintenance, body temperature regulation, growth and locomotion. O growth, reproduction, protein synthesis and body temperature regulation. O locomotion, growth, cellular maintenance and reproduction. O body temperature regulation, cellular maintenance and locomotion. cellular maintenance, growth and reproduction.

1)  Which two forces are most responsible for moving ions into and out of your neurons?     magnetic and electric     gravity and diffusion     reuptake and enzymatic movement     diffusion and electrostatic pressure 2)   The roughly 90-minute cycle of altertness during the day, which then also affects our sleep cycles at night, is called the     biological clock     basic rest activity cycle     circadian rhythm     intradial cycle

Part 1: Explain the term 'negative feedback', and use the example of blood glucose homeostasis to explain how a negative feedback loop works.

Tissues, Organs, & Systems Multi-cellular organisms have many cells that work together in specific ways, each group performing certain functions. When each group does its part, the organism gets everything that it needs. A Tissue is a large group of cells that all have the same purpose or function. Each kind of cell has unique characteristics such as shape, size, flexibility, color and texture. Nerve cell combined with other nerve cell to make nerve tissue. Muscle cell combined with other muscle cell to make muscle tissue. Bone cell combine with other bone cell to make bone tissue. An Organ is a group of tissues that work together to do a certain job for the body. Some of the human body’s organs include the stomach, lungs, heart, kidneys, brainand liver. Some of a plant’s organs include roots, stems, fruit and leaves. When several different organs join to meet the organism’s needs, they are working together in an organ system. There are several different organ systems constantly…

Endothermic animals can maintain consistent temperature conditions by generating, main- taining, and regulating their body heat. Under cold conditions, more body heat becomes lost to the environment. Endothermic ani- mals rely on different mechanisms that allow them to maintain their body heat. Which of the following mechanisms that occur in endothermic animals does not describe a mechanism by which they maintain their body heat under these types of conditions? A B с D Some endothermic animals hibernate during extreme environmental conditions, which decreases the rate of metabolic reaction and decreases heat loss. The tissues of the blood vessels of many endothermic animals can dilate and move closer to the skin, allowing for heat to move more readily into the environment. Shivering, which can occur involuntarily in most endothermic animals, produces rapid muscle contractions, which increase the rate of cellular respiration and thereby increase heat production. Layers of densely packed…
