What is the water intake of gymnosperms​
ad-work [718]

Answer:

Check down

Explanation:

Gymnosperms, like angiosperms (the flowering plants), differ from seedless plants (like mosses and ferns) in not requiring water for sperm to swim in to reach the egg. This means that the movement of pollen (male gamete) to ovule (female gamete) in seed plants relies on airborne transport, not water transport.

How would you describe the relationship that gravity has with mass and distance.
PSYCHO15rus [73]

Answer:

Mass does not affect gravity and distance has an indirect relationship.

Explanation:

The equation for gravity is, g = \frac{GM}{R^{2} }

where, G = gravitational constant

             M = mass of the planet

             R = distance between the bodies (object and center of planet)

so, gravity depends on the mass of planet,  not on mass of object

 and is inversely proportional to sqaure of distance.
