Answer: THE ANSWER IS FALSE.

Given our knowledge of ecosystems, we can confirm that the diverse habitats found at one location near the equator are due to the changes in elevation.

The effects that elevation has on the climate are what enable the diversity of habitats on a single mountain. As elevation increases, atmospheric pressure decreases. This decrease in pressure then causes a decrease in temperature.

The base of the mountain is a dry and hot habitat, while as we travel upwards towards higher elevation we see a transition in habitats into a more tropical forest style and then eventually an alpine tundra, further proving the claim that elevation lowers the temperature.

The correct answer is  a. absent spinal reflexes below the level of injury.

Explanation:

Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.

The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.

Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.

While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

The Earth's systems are interconnected and constantly changing, and these changes can have significant effects on the growth of life on Earth.

In the text "Changes on Earth and Changes in Life", the author discusses how changes in the Earth's atmosphere, geosphere, hydrosphere, and biosphere have shaped the evolution of life on our planet.

One example the text provides is the impact of changes in the atmosphere on the growth of life. During the early stages of Earth's history, the atmosphere was primarily composed of carbon dioxide and methane, which made it difficult for most life forms to survive.

However, as photosynthetic organisms evolved and began to produce oxygen, the atmosphere gradually became more hospitable for other forms of life to thrive. This allowed for the evolution of more complex organisms, including animals and humans.

The text also highlights how changes in the geosphere can affect the growth of life. For example, tectonic activity can create new land masses, change sea levels, and alter the distribution of nutrients in the soil, all of which can impact the survival and growth of different species

. Additionally, volcanic eruptions can release large amounts of gases and ash into the atmosphere, which can have immediate and long-term effects on climate and ecosystems.

Finally, the text discusses the impact of changes in the hydrosphere on the growth of life. For example, changes in ocean temperatures and currents can alter the distribution of marine life, while changes in freshwater availability can affect the survival of land-based species.

Overall, the text makes it clear that changes in Earth's systems have profound effects on the growth and evolution of life on our planet. Understanding these changes is crucial for predicting how different species will respond to ongoing environmental changes, such as climate change and habitat destruction.
