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).

Select the correct answer.
Sea anemones are predatory Invertebrates with stinging tentacles that can paralyze many sea animals. The clownfish Is Immune to the sting of
the sea anemone and actually lives among its tentacles. The relationship is mutually beneficlal-the clownfish often lures meat-eating animals
over to the anemone, and the anemone beneflts from the meal. The clownfish often gets to eat
leftovers from the anemone's meal.
When the clown fish Is ready to lay eggs, It lays them near a sea anemone. How's this a reproductive strategy?
O A. The sea anemone protects the clownfish's eggs from predators.
O B. The sea anemone fertilizes the clownfish's eggs.
O C. The sea anemone provides nourishment for the clownfish's eggs.

Explanation:
The cells were kept in a dilute salt solution. They were then transferred to distilled
water.
Explain what will happen to each of these two cells when they are placed into distilled water.
When plant cells are placed in salt solution their appearance is different to when they are placed in distilled water. ... Therefore, water moves out of the cell across the partially permeable membrane by osmosis and the cell becomes flaccid as the cell membrane peels away from the cell wall
Select three examples of resistance to antibiotics that is due to an altered cellular target of the drug. Multiple select question. The activity of beta-lactamase Addition of acetyl-CoA to chloramphenicol Alteration of an enzyme involved in folic acid synthesis A change in the structure of 23S rRNA The terminal D-alanine of pentapeptide mutates to D-serine
Answer:
- Alteration of an enzyme involved in folic acid synthesis
- A change in the structure of 23S rRNA
- The terminal D-alanine of pentapeptide mutates to D-serine
Explanation:
Antibiotic resistance is the phenomenon by which microorganisms naturally have, acquire, or develop the ability to defeat the drugs designed to eliminate them. For example, trimethoprim is able to bind with the enzyme dihydrofolate reductase (DHFR) in order to inhibit the folic acid synthesis pathway. Sulfonamides (sulfa drugs) competitively inhibit the incorporation of para-aminobenzoic acid (PABA) into folic acid and thus also prevent the synthesis of folic acid. Ribosomes are organelles where proteins are synthesized. The 23S rRNA is a component of the large subunit (50S) of bacteria and archaea ribosomes. In consequence, it is expected that a modification in the structure of 23S rRNA alters protein synthesis. Finally, vancomycin acts by binding the terminal D-Ala-D-Ala residues of the polymeric lipid-PP-disaccharide-pentapeptides and thus inhibits cell wall synthesis in Gram-positive bacteria. In consequence, it is expected that a mutation at the terminal D-alanine that modifies this sequence alters the vancomycin binding site and thus also confers antibiotic resistance.
DNA replication and DNA synthesis are the same process.

Which of the following functions at the same organizational level as the kidney in the human excretory system?
A. skeleton
B. epithelial tissue
C. urinary bladder
D. a squamous cell
Answer:
urinary bladder
Explanation:
In biology, there are five levels of organization namely: cell, tissue, organ, system, and organism. A collection of one forms the other, starting from the smallest CELLS. The human excretory system consists of organs that make it up.
Kidney is one of the organs that make up the excretory system. According to this question, the urinary bladder is also an ORGAN, which means that the kidney and bladder as ORGANS are functioning at the same level of organization in the excretory system.

Which is an example of why the process of photosynthesis is important to life on Earth?- - Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
- Fungi use photosynthesis to decompose dead and decaying plant matter.
- Ectothermic animals use photosynthesis to convert sunlight into energy for cell functions.
- Green plants use photosynthesis to remove oxygen gas from the atmosphere and replenish the earth’s carbon dioxide.
Answer:
The correct answer is: A) Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
Explanation:
Photosynthesis is the process by which green plants, which include algae, take in the energy from the sun and combines it with carbon dioxide (and water) to form benificial sugars.
Photosynthesis refers to the process by which the green plants, as well as algae, utilize the energy from the sun in combination with the carbon dioxide as well as water to form simple sugars. This is how the harmful gas carbion dioxide can be destroyed and elimanated.

How many alleles are in the gene pool?
Answer:
40 b alleles
Explanation:
Only 40 b alleles are present in the gene pool, so genetic diversity is lower. The use of gene pools allows population geneticists to see variation and the influence of natural selection in detail.

where does reabsorbtion of glucose take place?
glomerulus
bowman's capsule
2nd coiled tubule
1st coiled tubule
Answer:
proximal tubule
Explanation:
Glucose reabsorption takes place in the proximal tubule of the nephron, a tube leading out of Bowman's capsule. The cells that line the proximal tubule recapture valuable molecules, including glucose.Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.
