Plant cells contain chloroplasts, which govern the photosynthesis in the cell.
Plant cells also have a large central vacuole, which is necessary to contain the water for photosynthesis.
These both benefit the cell as they provide for photosynthesis.
Answer:
four quadrant, nine regions, abdomen or superficial organ
Explanation:
The body ventral side consists of abdominal and pelvic cavities that are primarily the digestive and reproductive system. The four quardrants helps in determing the site for performing surgery, also location of tumors mass. The nine region provide the information about origin of pain associated with the particular organ located in the cavity.
The abdominopelvic cavity can be divided into a total of <u>four</u> quadrants or <u>nine </u>regions. The central point of reference for dividing the abdominopelvic cavity into quadrants or regions is the <u>abdomen or superficial organ. </u>
Answer:
e) directional selection
Explanation:
Directional Selection:
- The type of natural selection that favors one of the extremes of the phenotype spectrum, shifting the allele frequency to one direction
- This type of selection selects against intermediate and one of the extreme phenotypes.
- In this particular case, the increasing pollution has pushed the plants to evolve better acid tolerance.
- This indicates that if the environmental conditions worsen, only the acid tolerant plants will be able to survive.
* Another example is illustrated in the image. The graph shows the shifts in allele frequency.
Sneezing causes the release of endorphins, which are hormones that trigger the brain's pleasure center, thus giving us a brief “feel good” effect
