Increased input to this cycle may be responsible for global warming.
carbon
potassium
nitrogen
phosphorus
Answer:
Carbon
Explanation:
Global warming is currently a great concern to the world. It is the process whereby the temperature of the atmosphere rises due to the effect of certain gases called GREENHOUSE GASES. Greenhouse gases are those gases that have the ability to trap and emit heat into the atmosphere e.g carbon dioxide, methane, CFC etc.
Carbon dioxide and methane, for example, are greenhouse gases that contain CARBON element in their structure. This implies that an increased input to the CARBON cycle may be responsible for global warming because more carbon input produces more carbon-based greenhouse gases, utterly leading to global warming.

Emphysema is a disease that damages alveoli describe how this disease would affect a persons ability to breathe then explain how emphysema would affect the concentration of oxygen and carbon dioxide in the bloodstream
Answer:
Emphysema is one of the lung disorders caused by damage to the air sacs in the lungs, which reduces the body's ability to take advantage of oxygen from the air. This results in inefficient breathing, because it takes extra effort to empty the air from the lungs. This disease progressively destroys the fibers that allow the airways to remain open. This problem causes the collapse of these pathways when a person exhales air. That is, the air that the lungs expel that contains carbon dioxide cannot get out, and consequently, the fresh, oxygen-filled air does not enter the lungs.
Explanation:
When we breathe, the air comes through the bronchial tree to a kind of small sacs called alveoli, which are located at the end of the bronchi and fill the lungs. From the lungs, oxygen is transported, through the arteries, to the different tissues and organs of the body. But, generally due to smoking, people with emphysema have damaged alveoli: the inner walls of these sacs weaken and break, which creates larger air spaces and therefore reduces the air exchange surface of the cells lungs. Consequently, the amount of oxygen that reaches the blood decreases and this can produce in the patient a sensation of shortness of breath, which is the frequent characteristic manifestation of this respiratory pathology. In the pulmonary alveoli, the oxygen in the air is exchanged for carbon dioxide in the blood. The walls of the air sacs are thin and fragile, so the injuries that occur in these air sacs are irreversible. Emphysema causes the alveoli - the small air sacs in the lungs that provide oxygen to the bloodstream - to weaken and they become less elastic. That means the body has difficulty getting enough oxygen or has excess carbon dioxide in the body.

My answer is down below. Don't directly copy because you will get plagiarism, and that's not what I want to happen to you. The only reason why I posted my answer is if you are in need of some help to think of things to write. Hope you enjoy it!
Explanation:
One of the sad things about this disease is that we currently do not have a cure for it. Which is very unfortunate for the people that end up getting it. There is some hope of relieving some pain, but there isn't a 100% cure. What emphysema does is it destroys the walls between your alveoli. What happens to your lungs? Well, it makes the lungs less able to absorb oxygen into our bloodstream and also remove carbon dioxide from our blood. The good news/bad news is that if you are diagnosed with emphysema you are likely to still live anywhere from 1-5 more years, which is pretty amazing that our body can last that long with damaged lungs.

Heredity is important to all living organisms as it determines which traits are passed from parent to child. Successful traits are more frequently passed along and over time can change a species. Changes in traits can allow organisms to adapt to specific environments for better rates of survival.
Explanation:
Look at the overall view of the onion root tip. Which phase does it look like most cells are in? Why are most cells in this phase?
Hello. You did not present the image to which this question refers, which makes it impossible for this question to be answered. However, I will try to help you in the best possible way.
I believe you are looking at cells from the tip of the root, in an experiment where the tip of the root of the onion was cut. To redo the tip of the root, the onion cells will undergo mitosis, which is the cell division where a cell originates from two identical cells.
Mitosis has five phases and all of them can be seen in the onion root cells according to the following characteristics:
1. Interphase: it is the moment when the cells increase in size and intensify their metabolic activity. The cells of the onion root will be in this phase when they appear as a completely dark and filled circle.
2. Prophase: The chromosomes condense and become visible and the cell membrane is flawed. In the cells of the onion root, you will be able to see this phase in cells that appear as an irregular circle, with a tangle of lines scattered inside.
3. Metaphase: The chromosomes condense further and connect to the spindle lines that are in the center of the cell. In the onion root cells, you will identify this phase in circles with a tangle of lines that are concentrated in the center of the cells.
4. Anaphase: The centromeres are separated and the sister chromatids migrate to the poles of the cell. You will be able to see this phase in cells that have a concentration of lines at both ends of the cell.
5. Telophase: the chromosomes are decondensed and the cell membrane is formed again while the cell separates into two. You will see this phase with the presentation of two cells.
To improve your understanding, the attached figure below shows how the cell appears in each phase.

When a volcano erupts, such as the Kilauea volcano in Hawaii, what do you think happens to the surrounding ecosystem? Explain how you think disruptions to the physical and biological components of the ecosystem would affect local populations.
Answer:
the surrounding ecosystem is nearly or completely destroyed this changes the physical and biological components of the system by killing any biological life and reshaping all structures with magma. this will affect the population by killing anything living haunting life for centuries until new life can start to form such as lichens to break down the hardened rocks nutrients into soil for life
The volcanic eruption of Kilauea volcano in Hawaii can have prolonging effects on the water and air quality, and in the livelihoods of the natives living in the surrounding region.
• The volcanic ash has been known to coat the highways, collapse roofs, ground airplanes, and put the natives at threat of developing respiratory ailments.
• The instantaneous influence of the eruption would be the destruction of wildlife and plant species.
• The pyroclastic flows, lava flows, and Kilaeua's discharge of toxic sulfur dioxide can lead to famine and ultimately the loss of livestock and other animals.
Thus, serious consequences would result due to the eruption of Kilauea volcano.

What organic molecule contains a carboxyl functional group and an amino functional group?
A. DNA
B. carbohydrate
C. lipid
D. protein
The basic amino group (NH2), the acidic carboxyl group (COOH) and the specific organic R group (or side chain) for each amino acid make up an organic molecule known as an amino acid. Thus, option D is correct.
What is Structure of protein?
The linear arrangement of amino acids within a peptide or protein constitutes its fundamental structure.
Conventionally, a protein's main structure is described from amino-terminal end to carboxyl-terminal end. Ribosomes in cells are most frequently responsible for protein production.
Peptide bonds are created when amino acids condense to form protein structures. The main structure of a protein is its arrangement of amino acids.
The dihedral angles of the peptide bonds determine the secondary structure, while the folding of protein chains in space determines the tertiary structure.
Therefore, a protein organic molecule contains a carboxyl functional group and an amino functional group.
