Explain how wildfires help restore soil nutrients to forest ecosystems.

Answers

Answer:

Wildfire help restore soil nutrients - Wildfire kills off the soil organisms that consume soil nutrients. Wildfires restore soil nutrients by decreasing the amount of underbrush in forests that contribute to nutrient loss. Wildfires break down organic material faster than decomposition, thus renewing soil nutrients more quickly.

Explanation:

Wildfire help restore soil nutrients by eliminating soil organisms that consume soil nutrients and decomposition of materials that help to renew soil nutrients.

What is soil nutrients?

Why are Canada’s Evergreen Forests considered “Earth’s Northern Lungs”? (think about the photosynthesis equation)

Answers

Answer:

Although trees have responded to global warming in the past‐ to temperatures higher than they are now- the rate of change predicted in the 21st century is likely to be unprecedented. Greenhouse gas emissions could cause a 3°-6°C increase in mean land surface temperature at high temperatures and temperatures latitudes. Despite this, few experiments have isolated the effects of temperature for this scenario on trees and forests. This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level. Adaptation to varying temperatures revolves around the trade- off between utilizing the full growing season and minimizing frost damage through proper timing of hardening in autumn and dehardening in spring.

B. The ecosystem can only support two offspring, reducing the fitness of both populations
C. The population of starlings have limited resources to care for their young
D. The starlings have fewer habits options and fewer offspring, reducing their fitness

Answers

Answer: C

Explanation: The population of starlings have limited resources to care for their young. This is why starlings can give birth to so many. The answer is C.

What is Stabilizing Selection?

The term Stabilizing Selection is unlike disruptive selection (diversifying selection) that tends to favor extreme traits when changes occur, stabilizing selection is defined as changes in population genetics in which extreme traits are not favored, rather, traits that are of intermediate variants are most favored and selected for.

In the scenario given, traits of producing fewer starlings or more are extreme traits that are not favored and have reduced fitness. Intermediate variants of producing moderate number of starlings that have high fitness demonstrates the type of selection that is referred by the term called stabilizing selection.

Therefore, Most Swiss starlings produce four to five eggs in each clutch. Starlings producing more than this have reduced fitness. The statements best explains this situation is the population of starlings have limited resources to care for their young. Thus, option C is correct.

There are many reasons why all humans do not perceive sounds similarly in our environment, including adaptation, hearing loss and/or deafness.
For 2A-2D, first determine whether the scenario is an example of sensory adaptation, conduction deafness, sensorineural deafness, and/or central deafness.
Second, for the scenarios that are examples of deafness, explain briefly how the scenario leads to deafness (i.e., how does the scenario alter normal auditory processing). If you have selected sensory adaptation as an answer, explain briefly why the scenario does not fall under the categorization of deafness. Use your own words to briefly explain - simply listing definitions is not sufficient. (2.5 points each for matching, 5 points each for correct justification)
2A. Listening to excessive loud noises everyday over years that causes loss of stereocilia
2B. Hearing construction outside when it first begins, but no longer noticing the sound minutes later
2C. Difficulty understanding speech, but no damage to ears or ability to understand nonverbal sounds
2D. A hole in the tympanic membrane caused by an ear infection

Answers

Answer: 2A Sensorineural deafness

              2B Sensory adaptation

              2C Central deafness

              2D Conductive deafness

Explanation: The human ear is divided into 3 parts:

Outer Ear: auricle, ear canal and tympanic membrane;Middle Ear: eardrum, tympanic cavity and ossicles (malleus, incus and stapes);Inner Ear: oval window, semicircular ducts (attached to cochlea and nerves), cochlea and auditory tube;

The Sensorineural deafness is a type of deafness caused by a damage in the inner ear, either the cochlea or the auditory nerve. It can happen because of medicine toxicity, exposure to noise along the years etc.

So, from the scenarios above, 2A is consistent with sensorineural deafness  since stereocilia are hair cells of inner ear.

Sensory adaptation is a phenomenom that happens when an individual's sensory receptors is exposed to a stimuli for a prolonged period of time. For example, the situation described in 2B. It is not considered deafness because it is not caused by a damage in any part of the ear.

Central deafness is a very rare case of deafness. The damage in this type of deafness is in the brain and not in any of the 3 parts of the ear. That's why the scenario in 2C is the example of this.

Conductive deafness is the second most common type of ear problem and it occurs in the outer ear. One of the causes is blockage in the ear canal by the ear wax, external bodies, osteomas (bone growth) or otitis (oute ear infection). An example of this type of deafness is scenario 2D.

For backstroke, you have to lay on your back. When I was on a swimming team, we'd always go on the diving blocks for all strokes except for backstroke.

Backstroke is the swimming stroke in diving that is not recommended to start a race

There are different types of swimming strokes such as

Butterfly Backstroke BreaststrokeFreestyle

The backstroke involves the use of the back on water for movement. This

stroke has a main advantage which is the ability of the swimmer to  breathe

well in water as his nose aren't always submerged in it.

The backstroke isn't however recommended to start a race as there is the

Explanation:

Answer:

Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth.

1. Form hypothesis: How does temperature affect oxygen concentrations?

If you're correct then I'll give you brainliest! c:

Answers

Answer:

Hello!!! Princess Sakura here ^^

Explanation:

First things first if we are going to form a hypothesis it doesn't matter if it is correct hypothesis are supposed to get tested.

So anyways....

I believe that the solubility of oxygen will decrease as the temperature increase.

I believed that because as temperature increases molecules start to move faster and move farther away from each other.

Temperature can have a significant impact on the concentration of oxygen in various environments. 1) Solubility of Gases, Oxygen Dissociation, Biological Processes.

Here's a step-by-step explanation of how temperature affects oxygen concentrations:

1. Solubility of Gases: The solubility of gases, including oxygen, in a liquid like water is affected by temperature. Generally, as temperature increases, the solubility of gases decreases. This means that at higher temperatures, less oxygen can dissolve in water or any other liquid.

2. Oxygen Dissociation: In the context of the human body, temperature affects the dissociation of oxygen from hemoglobin in red blood cells. As temperature increases, the affinity between oxygen and hemoglobin decreases. This means that oxygen is more readily released from hemoglobin and made available to tissues and organs. Conversely, as temperature decreases, the affinity between oxygen and hemoglobin increases, making it more difficult for oxygen to be released.

3. Biological Processes: Temperature also affects the metabolic rates of organisms. Generally, as temperature increases, metabolic rates increase, leading to higher oxygen consumption. For example, in aquatic ecosystems, warmer water temperatures can enhance metabolic rates of aquatic organisms, leading to increased oxygen demand. Conversely, lower temperatures can slow down metabolic rates and reduce oxygen demand.

It's important to note that the specific effects of temperature on oxygen concentrations can vary depending on the system or environment being studied. Different factors such as pressure, salinity, and the presence of other substances can also influence the relationship between temperature and oxygen concentrations.
