The arrows in the chart above represent the movement of carbon between four reservoirs: the ocean, plants, fossil fuels, and the

atmosphere. The numbers in the blue boxes show the gigatons of carbon moving each year. More carbon is moving into the vegetation for photosynthesis than is moving out to the atmosphere via respiration. This means that the vegetation reservoir is a carbon sink, taking in more carbon from the atmosphere than it is releasing to the atmosphere. A carbon source is the opposite. A reservoir that behaves as a carbon source releases more carbon to the atmosphere than it takes in.
Consider the statements listed here. Do they accurately describe potential changes in the model? Choose all that are correct:

1 - Deforestation would result in a decrease in the carbon sink.
2- Increased use of alternative energy sources such as solar and wind energy would 3 3 - result in a decrease in released or sourced carbon.
4 - If we consider non-industrialized countries, the model would remain the same.
5 - If global warming continues, we would expect a change in the amount of carbon found in the ocean reservoir.
6 - Combustion of fossil fuels acts as a carbon sink.
7 - All carbon in the atmosphere is made by humans.

Answer:

Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.

2 The second most important lifestyle change is to eat less meat, with particular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.

List the cell organelles involved in energy generation for the cell.
kompoz [17]

Answer:

Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

Define homeostasis autotroph and mitochondria
Hatshy [7]
Homeostasis is the equilibrium of a cell.

Autotrophs make their own food through photosynthesis.

Mitochondria undergoes cellular respiration and is often referred to as the "powerhouse of the cell".

The question is incomplete. Here is the complete question.

Read each description below regarding the dual innervation of the ANS. Then click and drag each into the appropriate category base on whether it is an example of antagonic or cooperative innervation.

The sympathetic division stimulates mucus production by salivary glands while the parasympathetic division stimulates enzyme secretion.

The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate.

During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

Antagonistic:

Cooperative:

Answer: <u>Antagonistic:</u> The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate; The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

<u>Cooperative:</u> The sympathetic division stimulates mucus production by salivary glands while the parasympathetic division stimulates enzyme secretion.; During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

Explanation: The peripheral nervous system is divided in <u>Somatic Nervous System (SNS)</u> and <u>Autonomic Nervous System (ANS)</u>. The first is responsible for sensory input and voluntary motion.

Autonomic Nervous System is divided into <u>Sympathetic and Parasympathetic divisions</u> and is controls the fight-or-flight and rest-and-digest situations. Usually, an organ with sympathetic and parasympathetic innervations have antagonic function, such as the heart rate -  one system causes the heart rate to increase while the other stimulates the rate to decrease. However there are cases in which the combination of the 2 systems cause an increase of stimulation, producing similar effects.

Analysing each category above, it is deductable that when the sympathetic stimulates mucus production and parasympathetic, enzyme secretion and when the parasympathetic stimulates arousal and sympathetic, orgasm, in both cases, they have cooperative innervation.

On the other hand, when sympathetic stimulates increase in heart rate and parasympathetic, decrease in the rate, as stated before, and one stimulates constriction of the pupils and the other, dilation of the them, those are examples of having antagonic innervation.

How are the hydrogen bonds in water responsible for many of the molecules unique characteristics?
DiKsa [7]

Hydrogen bonds exhibit the stronger intermolecular force, and water is a polar molecule, so the hydrogen bonding create strong forces which take more energy to break (causing the surface tension of water), and due to the polarity water molecules “stick” to one another which causes the edges to rise up in a tube, forming a meniscus
