<u>Answer</u>: A) Africa and South America only
As shown in the map, the fossil evidence suggests that Cynognathus lived on the modern day continents of South America and Africa. Thus, from this distribution and the fragmentation of the ancient landmass into today's continents, result in the distribution of Cynognathus offspring species also only within the continents of Africa and South America.
The correct answer would be B.(2nd one)
There are seven major classes of nutrients:
carbohydrates, fats, fiber, minerals, protein, vitamins, and water.
If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.
Answer:
Option A 400 individuals
Explanation:
Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.
N = (MxC) / R
Where N = estimated Number of individuals in the population
M = number of individuals captured and Marked = 200
C = total number Captured the second time (with and without a mark) = 200 and
R= number of individuals Recaptured (those with a mark) = 100
Thus, we have
N = (MxC) / R
= (200 x 200) / 100
= (40,000) / 100
= 400 individuals.
