Answer:
b. typify a population in which all ages have an equal chance of surviving. → YES
e. are typical of annual plants → YES
Explanation:
Different species have survival curves differently shaped. In general terms, there are three different survival curves.
- Type I. Mortality often occurs at the end of the cycle, representing species with low mortality. Organisms exhibiting this type of survivorship curve have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.
- Type II. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care.
- Type III. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.
Type II survivorship curves:
a. are characteristic of humans and elephants → No, this is Type I curve
b. typify a population in which all ages have an equal chance of surviving. → YES
c. indicate a high mortality rate in the very young. → No, this is Type III curve
d. show that very few young are produced, that each is given parental support, and that most individuals live a relatively long life and die of old age. → No, this is Type I curve
e. are typical of annual plants → YES
Answer:
ample sunlight
steady nutrient supply
Explanation:
Neritic zine is the shallow end of deep water bodies.
This end receives stable temperatures of about 24 degrees celsius.
This area permits photosynthesis since light penetrates to the bottom, this is the reason why planktonic plants survive here.
The region has got steady salinity and because of its favourable nature, it has got many living organisms.
Answer:
B. Constants
Explanation:
Constants are the factors that stay the same throughout the entire experiment no matter which group. The definition of a constant is "a situation or state of affairs that does not change." this furthers the point that constant is the correct answer because they don't change in the experiment.
