There are 4 different animals at a farm. There are 19 more cows than Than sheep

19 ducks more than hens

So there are more hens than cows. How many animals are there in all.

Step-by-step explanation:

As per question

Cows - sheep = 19

Ducks - hens = 19.

One more relation between cow and hens should be given or given but data is missing. Necessary information is missing to find total number of animals. This is all one can do as per provided data.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
