Hope it helps!~ (Sorry I you get it wrong or I got It wrong-)

Explanation:

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. ... Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants.

~The Confuzzeled homan

Answer 2
Primary Succession follows the formation of new land surfaces consisting of rock, lava, volcanic ash, sand, clay, or some other exclusively mineral substrate.
This means that there is NO SOIL present. (Soil is a mixture of mineral material, decaying organic material, and living organisms. The area is barren in primary succession.)
Secondary Succession follows the destruction or partial destruction of the vegetation area by some sort of disturbance, like a fire, windstorm, or flood that leaves the soil intact.
Pioneer species initiate recovery following disturbance in both primary AND secondary successions. Pioneers "pave the way" for later colonists (plant species) by altering the biotic and abiotic environment
Climax community describes an end product of succession that persists until disturbed by environmental change. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees. Examples of Secondary Succession
Fire. Fire is one of the most common causes of secondary succession and is an important component for the renewal and vitality of many types of ecosystem. ...
Harvesting, Logging and Abandonment of Crop Land. ...
Renewal After Disease. ...
Gap Dynamics. Examples of Primary Succession
Volcanic eruptions.
Retreat of glaciers.
Flooding accompanied by severe soil erosion.
Landslides.
Nuclear explosions.
Oil spills.
Abandonment of a manmade structure, such as a paved parking lot. Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. ... Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. How does an area move from a sterile, barren wilderness to one full of life? Barren rock from beneath a retreating glacier, or due to a volcanic eruption. Low-growing plants such as mosses, ferns, and lichens begin to colonize. Fast-growing grasses, flow- ering plants, and small shrubs begin to take root. The ecosystem may have been stopped from reaching its full climatic climax or deflected towards a different climax by activities such as:
Cutting down the existing vegetation.
Burning as a means of forest clearance.
Planting trees or crops.
Grazing and trampling by domesticated animals.
Harvesting of planted crops. is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
The pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants. Primary succession is a change in vegetation which occurs on previously unvegetated terrain (Barnes et al. 1998). Examples of where primary succession may take place include the formation of new islands, on new volcanic rock, and on land formed from glacial retreats.

Explain how considerations for human health help drive environmental policy decisions.

Answers

Answer:

Humans impact the environment, which can, in turn, have an effect on human health. Pollution is caused by human activity, and it also affects human health. Air pollution can cause respiratory problems and water pollution can lead to digestive problems. As human health is affected by these issues, concern increases and policies are enacted that address the causes of the issues. These policies do benefit the environment, but are, in part, brought about by concerns over human health.

Answers

Answer:

C) The moon's shadow falls on Earth

Explanation:

I got it right on a quiz :)

During a solar eclipse the moon’s shadow falls on Earth. Hence option c is correct.

What is solar eclipse?

Solar eclipse is defined as the Moon blocks some or all of the Sun's light from reaching Earth as it travels between Earth and the Sun. Eclipses of the sun happen when the moon passes in front of the earth and the sun. Earth is covered in a shadow because the moon prevents the sun's light from reaching it. If the moon fully obscures the sun, it is said to be a total solar eclipse.

When the Moon travels directly between the Sun and Earth, a solar eclipse occurs, covering Earth's surface with its shadow. The Moon's orbit doesn't quite align with the Sun and Earth, thus its shadow typically crosses the planet either above or below.

Thus, during a solar eclipse the moon’s shadow falls on Earth. Hence option c is correct.

Which is required for both anaerobic respiration and aerobic respiration?
oxygen
O water
O mitochondria
O glucose

Answers

Answer: Glucose

Explanation: Substrate is always required. Glucose is the substrate. Anaerobic respiration in absence of o2 and aerobic in presence of o2.

Aerobic respiration totally converts glucose into carbon dioxide and water, whereas anaerobic respiration only fully converts glucose into lactic acid or alcohol (alcohol fermentation) (lactic acid fermentation). Thus, option D is correct.

What similarity in anaerobic and aerobic respiration?

The fact that glucose is used as the first molecule in both aerobic and anaerobic respiration is one of their similarities.

Additionally, both aerobic and anaerobic respiration result in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.

For a modest output of ATP, glucose is partially broken down in the cytosol during anaerobic respiration.

For a higher yield of ATP, aerobic respiration uses oxygen to completely break down glucose in the mitochondria.

Therefore, glucose is required for both anaerobic respiration and aerobic respiration.

What evidence partly supports the idea that the carbon in the cellulose of the tree is the same

O The carbon combined with oxygen to make CO2.

O A chemical reaction occurred that converted sugar from within the tree into starch.

O The oxygen in the cellulose is the same oxygen that was in the air.

O A chemical reaction occurred in which the carbon in the atmosphere became part of a sugar molecule.

Answers

If the oxygen in the cellulose molecule found in a tree is the same oxygen that was found in the air, it can be used as evidence to support that the carbon in the cellulose is the same as the one in the atmosphere.

Carbon fixation

Carbon, in the form of carbon dioxide, in the atmosphere is fixed into plant tissues as carbohydrates during the process of photosynthesis.

Oxygen is released during the process but the oxygen comes from the splitting of water.

Thus, if the oxygen found in the cellulose of a plant corresponds to the oxygen found in the atmosphere, it is an indication that the carbon in the cellulose is also the same carbon in the atmosphere.
