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
Answers
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.

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?
Answers
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.

Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.

An animal with no natural enemy is a ____________.
Answers
Answer:
predator or a.pex predator
An animal with no natural enemy is an apex predator. Apex predators are also known as top predators or alpha predators.
They are species that reside at the highest level of the food chain within their ecosystems. They have no natural predators and primarily feed on other animals. Apex predators play a critical role in maintaining the balance and functioning of their respective ecosystems.
These predators are often characterized by their exceptional hunting skills, agility, strength, and ability to control the populations of their prey. They exert top-down control on the food chain by keeping the populations of lower-level consumers and herbivores in check, which in turn has cascading effects on the entire ecosystem. Thus, apex predators have no natural enemies.

Do your experiments suggest that mushrooms are decomposers (organisms that break organic matter down to simpler, inorganic matter)? Explain.
Answers
Answer:
Explanation:
As we know mushrooms help to decompose dead organisms, and it helps breaks down dead plants and or, dead animals so yes I would suggest that mushrooms are decomposers.
Mushrooms are decomposers because they are capable of breaking down dead and decaying organic matter into simpler and inorganic matter to synthesize their own food.
What are the advantages of Decomposers?Decomposers are only living forms that are capable of converting organic matter into inorganic one which is easily consumed by the roots of plants for their metabolism.
Mushrooms form a web of mycelium that expands deep into the soil to decompose dead organic matter with the help of their unique enzymes.
It also plays a key role in nutrient recycling and makes nutrients available to plants in inorganic forms.

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.
