Answer
I'll assume this means adding additional oxygen to the atmosphere.
Paper airplanes now fly farther. With all that extra air, the air pressure near the surface increases significantly. Gliders, parachutists, birds and paper-plane hobbyists enjoy greatly improved performance.
Everyone gets better gas mileage. Oxygen-enriched air improves engine performance by producing hotter reactions and reducing the proportion of nitrogen, which reduces heat transfer (Page on Energy.gov)
Higher elevation Biomes become inhabited by more vertebrates. Areas such as the high Himalayas or high Andes are no longer off-limits to animals without special adaptations to increase their levels of hemoglobin.
Insects of unusual size. Many insects rely on gaseous diffusion to for respiration, therefore the maximum body size depends on the proportion of oxygen gas in the atmosphere. Most bugs get bigger, some smaller (see Atmospheric oxygen level and the evolution of insect body size)
Everyone feels more alert, active, and happier. All that fresh oxygen improve our cognition, alertness, and physical performance. As a result, most athletic records would likely be broken by oxygen-enriched athletes.
We get sick less often. Neutrophils, soldiers of the immune system, destroy bacteria by using NADP oxidase to pump ions into, and disrupt, intruding cell's membranes causing rupture. More oxygen, more oxidase. (Page on Nih.gov)
We die younger. Free radicals (i.e. O2-) are thought to exacerbate the aging process through Oxidative stress, which interferes in numerous cellular processes: protein production, DNA replication, intercellular communication, and are also thought to contribute to MS, Alzheimers, Parkinsons, and a host of other ailments.

Describe the two patterns used to describe carrying capacity: Peak phenomena and Sigmoid phenomena
Answer:
Peak phenomena- food resources guide population growth, but the natural tendencies that manage population size, like birth and death rates, don't stabilize the population. Sigmoid phenomena- reveals the carrying capacity at the stability point.
Explanation:
Answer:
According to quizlet it states, "Peak phenomena- food resources guide population growth, but the natural tendencies that manage population size, like birth and death rates, don't stabilize the population. Sigmoid phenomena- reveals the carrying capacity at the stability point."

What type of diffusion is aided with a transport protein?
a. Osmosis
b. Permeated diffusion
c. Facilitated diffusion
d. Osmotic diffusion
Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
Which of the following would contain the largest concentration of digestive enzymes?
cell membrane
ribosome
chloroplast
lysosome
The LYSOSOME contains the largest concentration of digestive enzymes. This organelle has an internal acidic pH required for these enzymes to carry out their functions.
The lysosome is a eukaryotic membrane-bound organelle that contains different types of hydrolytic enzymes to degrade cellular components.
This organelle (lysosome) is part of the endomembrane system, which also includes the endoplasmic reticulum, Golgi apparatus, transport vesicles and nuclear envelope.
The main functions of the lysosomal enzymes include degradation and recycling of cellular byproducts, and metabolic roles.

Which of the following refers to the just-noticeable difference between two stimuli?
A) Absolute threshold
B) Sensation
C) Perception
D) Difference threshold
E) Subliminal stimulus
Difference threshold refers to the just-noticeable difference between two stimuli (Option D). This difference represents the minimum level of stimulation that can be detected by an individual at least half the time.
An absolute threshold can be defined as the lowest level of a stimulus which can be detected by a person at least half the time.
In psychology, an absolute threshold is defined as the minimal amount of energy required to achieve the stimulation of the sensory receptors.
Stimuli from the surrounding environment include touch, light, sound, etc.

allowing water to enter the cell, and export material out of the cell?
Answer:
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Describe how photosynthesis transforms energy from sunlight to chemical energy?
Answer:
Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.

Lillian parents are farmers. There are two types of fertilizers on the market. Both brands claim to grow carrots fastest. Plan and design an experiment to help Lillian's parents. Identify the independent, dependent and a control variable
The experiment to help Lillian's parents will consist of planting various carrots using both kinds of fertilizers, and maintaining a constant carrot type, amount of light, and amount of water throughout each plant.
In order to perform an accurate experiment, we need to identify three kinds of variables:
Independent variableDependent variableControl variableIn an experiment, the Independent variable is one whose value does not depend on the others. What this means is that this variable will not react to changes that occur in others. In this experiment, the independent variable is the fertilizer, given that it is not affected by the species of carrot, type of soil, or any other variable present.
The dependent variable in an experiment is just the opposite, it is, as the name implies, a variable whose value depends on the other variables present. In an experiment, this variable represents the data that we seek to measure. For this experiment, the dependent variable is the growth rate of the carrots because it is affected by the amount of water, light, and type of fertilizer we use, as well as being what we wish to measure.
Finally, the last variable we must identify is that of the control variable, also known as the constant or standardized variable. This variable is of vital importance for the accuracy of any experiment. This variable corresponds to those factors which we maintain constant through each trial in the experiment, for the example above, it is the amount of water and light, as well as the type of carrot, Lillian's parents will use.

Wjy is the increase in atmospheric carbon dioxide dangerous?
Answer:
The gas inhibits the escape of heat from Earth’s
Explanation:
This is the main cause of global warming. They cause climate change by trapping heat and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
The earth temperature depends upon the balance between the incoming radiation from the sunlight and the energy that is reflected back to space. Carbon dioxide absorbs the heat sent to earth by the sun, it acts as an insulator of the earth and helps to keep the atmosphere warm and make suitable for life process.
But, when the concentration of carbon dioxide in the atmosphere is increased, it means more and more increase in the temperature of the planet and cause global warming and make the life difficult on the planet. As a result of that whole life on the earth would be in danger.
Answer:
If you increase carbon dioxide, the temperature can go up causing our earth to have global warming problems.
