Hi,

A ball thrown in the air has the highest potential energy when it is at the top of its trajectory, because it is at the point at which it has maximum vertical height and its vertical velocity is 0 (its not moving up or down at that point)

Hope this helps,

Jeron

During ________ an egg ruptures from the follicle, leaving behind the ______________ which secretes estrogen in preparation for
Dominik [7]
The correct answer is "ovulation" and "corpus luteum" respectively. In ovulation, the egg ruptures from the mature follicle (called the Graafian follicle). This process is preceded by the sudden rise in luteinizing hormone. The follicle now becomes the corpus luteum, actually does not secrete estrogen, it secretes progresterone which prepares the uterine lining for pregnancy.

A marine ecologist counts the number of crabs in three different intertidal regions that are each two hectares. The crab counts
romanna [79]

Answer:

Density is nearly 3 cabs per hectare

Explanation:

Given -

There are three three intertidal regions.

Area of each intertidal region is 2 hectares.

Number of crab in the intertidal regions are as follows -

Intertidal region I - 7

Intertidal region I - 2

Intertidal region I - 6

Sum of crabs in all three regions is equal to

7 + 2+ 6\\= 15

Total area of all three intertidal regions is equal to

2 + 2+ 2\\= 6 hectares

Now density per hectare is equal to total population of crab divided by total area of all the three intertidal regions

Density = \frac{15}{6} \\= 2.5

Density is nearly 3 cabs per hectare
