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

Which among the following mineral groups, if any, contain silicon: halides
carbonates or sulfides? Explain.
Answer:
The correct answer is: none of these mineral groups contain silicon.
Explanation:
The only minerals that contain silicon are the Silicates, for example, SiO2 (silica).
Halides are minerals that consist of a combination of elements from the seventh group that can form salts (like fluorine or chlorine), with other elements such as calcium and sodium. For example: NaCl (sodium chloride).
Carbonates are compounds that contain carbon and oxygen, for example, CaMg(CO3)2 (dolomite).
Sulfides consist of sulfur with another element. For example: ZnS (zinc sulfide).
Why should muscles not be dissected at the points of origin and insertion
Answer:
The muscles should not be dissected at the points of origin and insertion due to the fact that the cell structures present here are a typical in nature .
Explanation:
The origin is where the muscle joins the stationary bone. The insertion is where it joins the moving bone. ... At the bone, the fibres of the tendon are embedded in the periosteum of the bone. This anchors the tendon strongly and spreads the force of the contraction, so the tendon won't tear away easily.
Most chemicals necessary for life dissolve in what?
Don't answer if you don't know.
Answer:Water is considered the “universal solvent” and it is believed that life cannot exist without water because of this. Water is certainly the most abundant solvent in the body; essentially all of the body's chemical reactions occur among compounds dissolved in water.
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. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Leaves are a plant's major site of photosynthesis and gas exchange
with the atmosphere. True or False?
Answer:
True
Explanation:
The cells in a middle layer of leaf tissue called the mesophyll are the primary site of photosynthesis. Small pores called stomata—singular, stoma—are found on the surface of leaves in most plants, and they let carbon dioxide diffuse into the mesophyll layer and oxygen diffuse out.

A. The starling parents do not care for their young, reducing their fitness
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
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.
Hope this helps!
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.
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.

Explain how wildfires help restore soil nutrients to forest ecosystems.
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.

1. Form hypothesis: How does temperature affect oxygen concentrations?
If you're correct then I'll give you brainliest! c:
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.
