Lack of light and animals affect the rate of photosynthesis
Answer:
Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).
Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.
In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.
Answer: Potassium-40 decays into argon gas over time.
Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.
Potassium-40 undergoes decay following first order kinetics as given below:
Answer: A) Balding
Explanation:
Balding is the most common pshysical change in middle-aged men.
Generally speaking, men between 35 and 40 years old develop a state of baldness that although it is not aggravated, it is notorious. Some men even begin to lose their hair at an earlier age, approximately 25 years old and older, although in those cases it is very likely that the cause is a genetic tendency.
Normally, after a certain age range (stated above) the hair fiber begins to lose strength and said follicles simply do not allow hair growth so fast as they did when the individual was younger.
