Count the number of new species that form in each group beginning at 60 mya (the first three species in each group were present

melamori03 [73]

Answer:

hello your question has some missing information attached below is the missing information

answer :

New planktonic larvae species = 10 species

New Non-planktonic larvae species = 26 species

Explanation:

calculate for the number of new species that form in each group

From the question it can seen that 3 species were present before 60 mya in each set

hence to calculate for the number of new species that form in each group

= Total number of species - number of species present at the beginning of 60mya

Group 1 ( New planktonic larvae species )

= 13 -3 = 10 species

Group 2 ( New Non-planktonic larvae species )

= 29 - 3 = 26 species

When the distance between the balls decreases, the size of the arrows increases. This shows that the gravitational pull

shepuryov [24]

True

Explanation:

The statement that when the distance between the balls decreases, the size of arrow increases because it shows the gravitational pull between the two balls which increases is true.

According to Newton's law of universal gravitation:

"The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of their separation".

Mathematically, the law is written as:

F = $\frac{G m_{1} m_{2} }{r^{2} }$
