El efisema pulmonar,provocado princioalmente por el consumo de cigarro, es una lesion que genera destruccion de los alveolos y, por lo tanto, zonas en las que no se produce el intercambio de gases ¿que consecuencias puede tener esta lesion en el organismo?
Answer:
El enfisema pulmonar disminuye la cantidad de tejido pulmonar, disminuyendo de este modo la cantidad de oxígeno que llega a la sangre (hipoxemia). El enfisema está asociado a diferentes trastornos incluyendo infecciones respiratorias recurrentes, pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores.
Explanation:
El enfisema pulmonar es una enfermedad causada por la destrucción de los alvéolos pulmonares la cual está asociada a un aumento en la dificultad para respirar. Las principales causas de esta enfermedad son la exposición continua al humo del cigarrillo y otras sustancias nocivas para la salud, como así también a contaminantes presentes en la atmósfera. El enfisema pulmonar va progresivamente destruyendo las paredes alveolares pulmonares y los vasos sanguíneos que las recorren, disminuyendo así la elasticidad pulmonar, aumentando la proporción de aire que recorre los pulmones y de este modo también aumentando la distensibilidad pulmonar. Esta enfermedad disminuye la capacidad de oxigenar la sangre, generando una sensación constante de falta de aire (disnea) y cuadros progresivamente más severos de hipoxemia. Cuando el enfisema pulmonar se encuentra en grado avanzado, la única opción viable es el reemplazo del órgano dañado mediante un trasplante pulmonar. El enfisema puede estar asociado a infecciones respiratorias recurrentes (resfriados, gripe), pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores (tobillos, pies y piernas).

Answer:
Lipids
Explanation:
read textbook
Fatty acids are a component of lipids macromolecules.
Fatty acids and lipidsFatty acids are a component of lipids. Lipids are a diverse group of macromolecules that include fats, oils, phospholipids, and sterols. Fatty acids are the building blocks of lipids.
They are long hydrocarbon chains with a carboxyl group at one end. Fatty acids can be saturated (no double bonds) or unsaturated (one or more double bonds).
When combined with glycerol, fatty acids form triglycerides, the most common type of lipid used for energy storage in organisms.

When a cell is deprived of oxygen, its lysosomes tend to burst and release their contents into the cell. As a result of this, that cell will Group of answer choices undergo cell division. recycle damaged organelles. produce replacement lysosomes. undergo self-digestion and die.
Answer:
The correct answer is - undergo self-digestion and die.
Explanation:
Lysosomes are cell organelle that is membrane-bound and has digestive enzymes in them. These cell organelle help in digesting cells that are worn out, ruptured cells deprived of oxygen by bursting themselves.
Its bursting nature also helps in digesting and killing antigens and microbes. It is a very essential cell organelle that helps in digesting and killing damage cell parts or cells.
When a cell is deprived of oxygen, its lysosomes tend to burst and release their contents into the cell, the cell will undergo self-digestion and die.
Explanation:
Lysosomes are cell organelles that are membrane-bound and contains digestive enzymes. These cell organelle help in breaking down cellular waste. When the cell is deprived of oxygen they burst themselves and release their content. It is a very essential cell organelle that helps in digesting and killing damaged cell parts, microbes, antigens, or cells.So, from this we can conclude that when a cell is deprived of oxygen, its lysosomes tend to burst and release their contents into the cell, the cell will undergo self-digestion and die.

The carrying capacity for a population of frogs in a rainforest ecosystem is 840 frogs, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for 212 frogs?
4 frogs per year
29 frogs per year
158 frogs per year
314 frogs per year
Answer:
4 frogs per year is the answer
In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K).
Formula used: dN/dT= rN{1-N/K}
Given: k= 840 frogs
N= 212, r= 1 year
To find: r=?
Solution:
putting value in equation:
dN/dT= rN{1-N/K}
dN/dT = 1 x 212 {1-212/840}
so, dN/dT= 158.57 ( approx)
Final answer: The correct option is (c)
158 frogs per year
Thus, we can conclude that 158 frogs per year will be the population of frogs.

ou have isolated a previously unstudied protein, identified its complete structure in detail, and determined that it catalyzes the breakdown of a large substrate. You notice it has two binding sites. One of these is large, apparently the bonding site for the large substrate; the other is small, possibly a binding site for a regulatory molecule. What do these findings tell you about the mechanism of this protein
Answer:
These findings tell us that possibly this protein has an enzymatic function, that is, it is an enzyme.
Its function can be catalytic as well as analytical.
The substrate binding site should be the largest, while the other regulatory site is the smallest.
Explanation:
This happens since hormones regulate their enzymatic activity through inhibitory sites.
They have another smaller binding site, where when an inhibitory molecule binds, it deforms the morphology of the protein causing it to no longer bind to its substrate at the binding site, therefore they inhibit the chemical reaction that is happening within the enzyme. both catalytic and analytical.
I need to know what which weathering it is
Answer:
the answer is D
Explanation:
Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off.

Ion pumps and phagocytosis are both examples of ________. endocytosis passive transport active transport facilitated diffusion 9. Choose the answer that best completes the following analogy: Diffusion is to ________ as endocytosis is to ________. filtration; phagocytosis osmosis; pinocytosis solutes; fluid gradient; chemical energy
Answer:
6. integral proteins
7. down; concentration
8. active transport
9. osmosis; pinocytosis
Explanation:
An integral protein is a protein that is permanently attached to a biological membrane. Some examples of integral membrane proteins include, for example, the insulin receptor, cell adhesion proteins (e.g., integrins), glucose permease, etc. Diffusion, also known as passive transport, refers to the process by which a substance/molecule tends to move from an area of high concentration to an area of low concentration. Moreover, osmosis is a type of diffusion by which a solvent (e.g., water) moves across a semipermeable membrane from a region of lower concentration to a region of higher concentration. Active transport refers to the movement of molecules/substances across a biological membrane against a concentration gradient. There are two types of active transport: primary active transport and secondary active transport. The primary active transport depends on a source of energy (e.g., ATP) for movement, whereas secondary active transport depends on electrochemical gradients to transport substances with the help of membrane transport proteins (i.e., cotransporters). Active transport involves ATP pumps that move ions into and out of the cell. Finally, endocytosis is the process by which cells absorb external material by engulfing them in transport vesicles, whereas pinocytosis refers to a type of endocytosis involving fluids that contain many solutes.

gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answer:
wind generated power plants. they have the lowest efficiency because it is not always windy and the wind varies everyday, thus the wind turbines will generate different amounts of electricity each day. They also can be very noisy and cause noise pollution. Wind Plants need good land place and these are mainly found in rural areas far from the city that the electricity is needed.
