Following the evaporation stage of the water cycle, the evaporated water

Answers

The water cycle is the continuous movement of water on thesurface of the Earth. Its physical processes arranged in order involve:Evaporation, Condensation, Precipitation, Infiltration, Runoff, and subsurfaceflow. Following the evaporation stage is the process of condensation.Condensation refers to the transformation of water vapor into liquid waterdroplets in the air. When this happens, fog and clouds are formed on theatmosphere of the Earth.

The water cycle may cause temperature and climate changes inthe environment because of the series of energy exchanges that occur during itsdifferent stages. Aside from this, the cycle allows for the transportation ofliquid into different bodies of water around the world making it responsiblefor maintaining most life and ecosystems in the planet. It also reshapes thegeological features of the Earth (e.g. erosion and sedimentation)

Discuss the relative degree of protection of organs in the dorsal body cavity compared to the ventral body cavity

Answers

The study of a living being is called biology.

The correct answer is mentioned below.

What is the dorsal and the ventral side?

  • The back side is known as the dorsal side and the front side is the ventral side.

The human body consists of body cavities that allow the organs to be accommodated. There are primarily two types of body cavities: the dorsal body cavity and the central body cavity. The dorsal body cavity is a space filled with fluid that surrounds the spinal cord and the brain. It is located on the "dorsal" or "backside" of the human body.

These structures are protected by the "skull" and the "spine" or the "vertebrae." The skull protects the brain, while the spine protects the spinal cord. This cavity is covered by meninges, which also serve as protection. It mainly functions to protect the central nervous system of the body. The ventral body cavity is located on the "anterior" or "front side" of the human body. This consists of the abdominopelvic cavity and thoracic cavity.

These cavities consist of organs in the human trunk, such as the heart, lungs, intestines, reproductive organs, and the like. The thoracic cavity is protected by the "rib cage." Unlike the ventral body cavity, the dorsal body cavity is well-protected because it houses very important human organs and structures

Hence, the correct answer is mentioned as follows

Why is homeostasis important?

Answers

homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly.
“What is homeostasis and why is it important? Give an example of a body condition that must be controlled and how.

In order to remember the definition of homeostasis it is useful to memorise the mnemonic ‘MACIE’; the Maintenance of A Constant Internal Environment. Conditions in the body must be constantly controlled because cells depend on the body’s environment to live and function. The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly.

Conditions that must be controlled include temperature, blood sugar level and water content and they are all controlled by different hormonal and nervous systems.

For example, the maintenance of body temperature is controlled by the brain. The body’s temperature must be kept at 37 degrees because this is the temperature at which enzymes optimally function.

Temperature receptors in the skin detect changes in the external environment and pass this information on to the brain’s processing centre, the hypothalamus. The hypothalamus itself also has receptors that detect changes in the blood temperature. If the external/internal temperature changes, the hypothalamus will automatically trigger changes in the body’s effectors (sweat glands and muscles) to keep our temperature constant.

If we are too hot; glands in the skin secrete sweat onto the surface to increase heat loss by evaporation.

If we are too cold; arrector pilli muscles in the skin contract and cause the hair on our arms to stand up straight, trapping a layer of warm air next to the skin to reduce heat loss. It is the contraction of these muscles that causes the appearance of goosebumps when we’re cold.”
