Answer:
Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments[1] and ecosystems, biodiversity, and natural resources[2][3] caused directly or indirectly by humans, including global warming,[1][4] environmental degradation[1] (such as ocean acidification[1][5]), mass extinction and biodiversity loss,[6][7][8][9] ecological crisis, and ecological collapse. Modifying the environment to fit the needs of society is causing severe effects, which become worse as the problem of human overpopulation continues.[10][11] Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth,[12][13] overconsumption, overexploitation, pollution, and deforestation, to name but a few. Some of the problems, including global warming and biodiversity loss pose an existential risk to the human race, and human overpopulation causes those problems.
Explanation:
The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities.[19] The atmospheric scientist Paul Crutzen introduced the term "Anthropocene" in the mid-1970s.[20] The term is sometimes used in the context of pollution emissions that are produced from human activity since the start of the Agricultural Revolution but also applies broadly to all major human impacts on the environment.[21] Many of the actions taken by humans that contribute to a heated environment stem from the burning of fossil fuel from a variety of sources, such as: electricity, cars, planes, space heating, manufacturing, or the destruction of forests.

The cell membrane performs several important functions in addition to separating the cytoplasm from the outside environment. It controls which molecules enter and leave the cell. The cell membrane is “selectively permeable,” which means it allows certain substances through and not others. One way that substances enter and leave the cell is through diffusion, the movement of particles from higher concentration to lower concentration. For example, if the concentration of salt molecules is higher inside the cell than outside, salt particles will move out of the cell. Diffusion is a type of passive transport, a movement of particles that does not require energy to occur. Facilitated diffusion is a kind of passive transport where proteins in the cell membrane help particles move from high to low concentration.
The cell membrane functions most like a?
Answer:The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.

Nancy is explaining why chlorophyll is classified as a plant pigment and how it is useful in photosynthesis. Which property of chlorophyll would be most appropriate for her to cite?
A. chlorophyll's ability to absorb light
B. chlorophyll's green color
C. chlorophyll's presence in chloroplasts
D. chlorophyll's reactivity with oxygen
Answer:
A. chlorophyll's ability to absorb light
Explanation:
Within the chloroplasts of plants, a complex biochemical mechanism, photosynthesis, takes place. Here, light energy is converted into chemical energy in the form of stable carbohydrates.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
In the chloroplast, the light-dependent and light-independent reactions in which sugars are formed occur. In the light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths.
Specifically, chlorophyll then forms photosystem complexes (PS I & PSII) with proteins- these absorb and transfer light electrons etc to other downstream reactions like photolysis and the electron transport chain.

Why is photosynthesis important for plants?
Answer:
Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration. It is important to note that not all plants photosynthesize. Some are parasites and simply attach themselves to other plants and feed from them.
Answer:
Photosynthesis is important for plants because it let them make their foods.

What arguments have been made with respect to the campaign for “clean coal”?
Answer:
Explanation:
Clean coal involves the use of technology to mitigate the health and environmental effects of burning of coal by capturing the emissions thereof. Since burning of coal (combustion) will normally release carbon or it's compounds; this is considered as a huge contributor to global warming, which is affecting lives on the planet. Thus, capturing combustion emissions such as carbon dioxide could help mitigate the effect of global warming.
Other gases emitted from the burning of coal are sulphur (IV) oxide, SO₂ and nitrogen oxides, which are huge causes of acid rain. SO₂ have been suggested to be removed from the atmosphere by flue-gas desulfurization while NO₂ has been suggested to be removed by selective catalytic reduction.
These arguments have been made to protect the earth and the lives that live on it since global warming and acid rain affect the lives of plants and animals while global warming affect the earth's climate.

If a person has a tidal volume of 550 ml and breathes at a rate of 14 times per minute, what is the minute ventilation rate?
Answer:
The minute ventilation rate = 7.7 Lpm
Explanation:
a) The tidal volume = 550 ml
Respiratory rate = 14 times per minute
Since minute ventilation (VE) is the total volume of gas entering (or leaving) the lung per minute, it is equal to the tidal volume (TV) multiplied by the respiratory rate (f).
This implies that Minute Ventilation = VE = TV x f
= 550 * 14
= 7,700 ml/min.
Therefore, the minute ventilation rate = 7.7 Lpm (7,700/1,000) or 7.7 liters per minute.
b) The ventilation rate is also known as the inhalation rate or breathing rate. It is the amount of air inhaled in a specified time period. Note that at rest, a normal person moves approximately 450 ml/breath * 10 breath/min or 4500 ml/min (4.5 Lpm).

Explanation:
Cardiac output (flow) is determined by a pressure gradient and a resistance g. Which of these variables do you think contributes most to the very large increase in flow in this athlete?
Answer:
Cardiac output depends on the resistance mainly of the cardiac muscle walls.
Explanation:
The resistance of cardiac tissue also depends on its ability to distend in the sarcomero, that is, on the initial length of the contraction, the greater this, the greater the resistance, the greater the pumping efficiency, but the greater cardiac wear, this Situation occurs in people who are athletes or athletes since they have higher cardiac output but greater efficiency at the time of blood ejection, this is how they oxygenate the tissues better.

QUESTION:
Evolution never occurs in a straight line. There are always branches and nodes that can be seen along the way. Based on the image, which two statements are true?
ANSWER CHOICES (have to pick 2 answers)
A. All organisms have had one common ancestor in the past.
B. Chimpanzees are more evolved than all other organisms.
C. Gorillas share an extinct ancestor with bonobos.
D. Humans and chimpanzees are equally evolved.
E. Orangutans are unrelated to gorillas or bonobos.
The correct answer iare A. All organisms have had one common ancestor in the past, and C. Gorillas share an extinct ancestor with bonobos.
Explanation
The image shows an evolutionary tree that resulted in species such as the chimpanzee, orangutan, gorilla, bonobo, and humans. This tree shows nodes, which are the points shown on it. These nodes represent an extinct species as a common ancestor of the species of the next node that are connected to it. Therefore, the correct answers are A. All organisms have a common ancestor in the past, this statement is true because all the species shown in the tree are the result of different divisions of a first species that lived 13 million years ago. The second correct statement is C. Gorillas share an extinct ancestor with bonobos. Because in the graph it can be seen that 6 million years ago there was a node/species that is the common ancestor of the gorilla and the bonobo.

Based on your knowledge of on-site centralired storage of nuclear waste, what do you feel is the most appropriate long-term solutionShould radioactive spent fuel roda be moved to and stored Yucca Mountain? Defend your decision using evidence.
Answer:
Yes
Explanation:
Because
The Yucca Mountain repository is the proposed spent nuclear fuel (SNF) and high-level radioactive waste (HLW) repository where both types of radioactive waste could be disposed. If constructed, it would use a tunnel complex approximately 1000 feet below the top of Yucca Mountain and about 1000 feet above the aquifer underlying the repository. The basic idea of geologic disposal is to place carefully packaged radioactive materials in tunnels deep underground. To achieve this, the Yucca Mountain repository would utilize a mixture of natural and engineered barriers to isolate the waste from the surrounding environment.
It is statutorily limited to containing 70,000 metric tons of spent nuclear fuel and high-level waste, unless a second repository opens during its operational lifetime.

compare amd contrast the working of a kidneys and the artificial dialysis
Answer:
Based on these data, the blood presented weekly to an average dialysis system in centre-based care in ANZ = 325 ml/minute (i.e. 0.325 L) x 60 minutes x 5 hours x 3 treatments/week = 292.5 litres.
Scroll back for a moment and compare: two normal kidneys receive 10,000 litres of blood/week but a dialyser (the artificial kidney) in ANZ gets a measly 300 litres to play with, if it's lucky.
Yet, while that is clearly a stark difference, the comparison in the US is even starker!
The average calculation for a centre-based patient in the US is: 400 ml/minute (i.e. 0.4 L) x 60 minutes x 3.5 hours x 3 treatments/week = 252 litres; a low volume by ANZ standards, even after (my view) the higher access-damaging pump speeds used in the US have been factored in.
To compare these differences in another way, in ANZ only 292/10,000 = 2.93% of the blood presented in a week to two normal kidneys is presented for dialysis. In the US, it is even less: a paltry 2.52% (= 252/10,000).
What about home-based dialysis?
As a comparison, many home patients, especially in ANZ, perform up to 8-9 hours (mean = 8.5 hours) of overnight, while-asleep dialysis for an average of 5 nights/week. Most who undertake these schedules also run access-friendlier pump speeds of 225-250 ml/minute (mean = 0.2375 L). This provides 0.2375 x 60 x 8.5 x 5 = 605 litres/week for dialysis.
In the US, the most commonly used home profile seems to be a 400 ml/minute x 2 hour/treatment x 6 treatments/week program; this is the one that is most often delivered by the NxStage system, a low-flow system that, by its design, offers less efficient solute clearance compared to the ANZ-preferred single-pass systems. Thus, US home patients under this model present 0.4 L x 60 minutes x 2 hours x 6 treatments/week = 288 litres/week to a less efficient system. While this “short daily” home model clearly presents more blood for dialysis per week than does US centre-based practice, it is still less than the average ANZ centre-based volumes and compares even less favourably with the 600+ litres/week that are presented to the more efficient single-pass systems used by many/most ANZ home dialysis patients.
