The fossil record clearly shows that ________. the fossil record clearly shows that ________. large complex organisms evolved long before simple. nearly all species that have existed in the past still exist today. all species evolve from pre-existing species. new species appear suddenly and fully differentiated, without an ancestral species. several different species can hybridize to produce a single new species

Answered by answersmine AT 22/10/2019 – 02:35 AM I think the answer is all species evolve from pre-existing species. This was based on Charles Darwin’s Theory of Evolution which he learned during his expeditions.He identified that some fossils have similarities with other existing animals, in which he believed were a part of …

In Texas, the population of a species of bats is decreasing at a rate of -0.121 per year. The population was 34,000 in 2000. According to the function; A(t) = A0e^(kt), what is the predicted population in 2015?

Answer: Population of bats in year 2015 is 5536. Step-by-step explanation: The given function A(t) = predicts the population of bats after t years. Here A(t) = population after ‘t’ years            k  = growth constant            t = time in years …

Which is a good example of adaptive evolution? The red fox that inhabits farmlands and forests has a red coat, but its relative, the kit fox, lives in a desert has a sandy–colored coat. Two birds of the same species separate during their migratory flight. After several years, their descendants are quite different from each other. Two species of fish try to swim against the current near a waterfall. One survives, but the other doesn't.

Which principle states that two species in the same habitat cannot have the same niche? niche exclusion principle competitive exclusion principle habitat exclusion principle population exclusion principle

Answer: competitive exclusion principle The competitive exclusion principle suggests that no two species can occupy the same ecological niche (functional role an organism performs in an ecosystem like type of food, and habitat chosen for living) in the ecosystem, the one which is stronger and superior over the other is …

Which of the following is not true about the distribution of species? a. A species’ native range does not include areas where it was introduced by humans. b. Some species have a range they inhabit only for breeding. c. Seasonal ranges include areas where species are found for part of the year. d. All the organisms in an ecosystem share distribution patterns.

Answer: d. All the organisms in an ecosystem share distribution patterns. Explanation: Native range is what is known in biology as the areas where a species is naturally found, not places were humans introduced them, species have some range only for breeding, for example some frogs only go into the …

MULTIPLE CHOICE VERY EASY!!!!! Which statement about the members of a population that live long enough to reproduce is consistent with the theory of evolution by natural selection? A. They are the ones that are best adapted to survive in their environment. B. They will perpetuate unfavorable changes in the species. C. They transmit characteristics acquired by use and disuse to their offspring. D. They tend to produce fewer offspring than others in the population.

In tropical rain forest, the animals will have to deal with higher temperatures and greater rainfall. One example of an adaptation they might need is a thin, water-proof coat. This will prevent heat from becoming trapped inside their fur/hair/feathers, and the water-absorbing coating will allow water to stick to the …

The rate (in mg carbon/m3/h) at which photosynthesis takes place for a species of phytoplankton is modeled by the function p = 120i i2 + i + 9 where i is the light intensity (measured in thousands of foot-candles). for what light intensity is p a maximum?

The given function is: P = 120 i / (i^2 + i + 9) or P = 120 i (i^2 + i + 9)^-1 The maxima point is obtained by taking the 1st derivative of the function then equating dP / di = 0: dP / di = 120 (i^2 …
