Answer:
d. One additional neutron
Explanation:
Phosphorus-32, a radioactive variant of phosphorus, possesses 15 protons and 17 neutrons.
Conversely, Phosphorus-31, the most prevalent isotope of phosphorus, contains 15 protons and 16 neutrons.
This indicates that one isotope has one more neutron than the other.
In trees and other plants, the presence of a cell wall gives the organism a protective barrier, contributing to its stiffness and rigidity, whereas animals lack this structure, allowing for greater movement.
Answer:
Exocrine glands are characterized by discharging their secretions into duct systems.
Explanation:
Exocrine glands:
These glands transport their secretions through a network of ducts that ultimately connect to the body's exterior. This means there is a direct continuity between the interior surfaces of the glands and their duct system with the external surfaces of the body (like the skin).
Examples of exocrine glands include gastric glands, salivary glands, and sweat glands.
Exponential Population Growth
Explanation:
The exponential population growth model forecasts that the per capita growth rate, r:
d. remains unchanged as the population enlarges.
A population is said to experience exponential growth when there are no constraints on its increase. All individuals have plentiful resources at their disposal, and the population showcases its inherent rate of growth. This is often termed geometric growth, where the rate of increase is reflected as a constant fraction or exponent applying to the entire population.
Answer:
Paraquat serves as a herbicide.
Explanation:
Coral bleaching wasn't induced by paraquat since it is a herbicide aimed at eliminating weeds, not algae. Coral hosts small algae essential for its coloration, hence applying paraquat wouldn't affect these algae, thus preventing coral bleaching. In contrast, if a different chemical that targets algae is used, it results in coral bleaching and turns the coral white.
