Homework Answers
Answer: option c is correct option
Species A might brach i to two or more species
Cladogenesis means branching suggested by Charles Darwin that some individuals of a species converted into another species while intial will also exist this leads to more no. Of species and hence species diversity formed.

Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? (5 POINTS) A: Climate change happens so fast, that there is not enough time for species to migrate to cooler areas. If they would migrate any faster natural selection could not keep up with them. B: The building plan of plants and animals is too complex. They cannot cope with the...

Bacteria of species A and species B are kept in a single environment, where they are fed two nutrients. Each day the environment is supplied with 19,860 units of the first nutrient and 31,950 units of the second nutrient. Each bacterium of species A requires 4 units of the first nutrient and 5 units of the second, and each bacterium of species B requires 1 unit of the first nutrient and 6 units of the second. What populations of each...

5. A paper published this year concluded that the giant Chinese paddlefish should be declared officially extinct. (15 pts) a. We often agree on the year an old species goes extinct, but we rarely agree on the year new species arises. Why? b. Why might we expect mass extinctions to be followed by adaptive radiations? c. Much of our evidence for mass extinctions come from shelled, near-shore organisms. Give two reasons for this. Reason 1: Reason 2: d. Suppose one...
Climate change is a threat to the existence of many species.
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

A native species of earthworm (species 1) has an Imax of 0.5, and a carrying capacity of 50 worms per square meter of soil. An invasive introduced earthworm species (species 2) has an I'max of 0.0, and a carrying capacity of 100 (per square meter). The niches of these two earthworms overlap to some degree, such that a2i = 0.8 and a2 = 0.6. Which of the following equations best describes the population growth rate of the invasive species, when...
