Within the water cycles, where do individual water molecules stay for the least amount of time?A: in the atmosphere


B: in the ocean


C: in deep groundwater


D: in shallow groundwater

Answers

Answer:

A: in the atmosphere

Explanation:

  • As the air is a mixture of gases and the air is continuously in motion as the water molecules are then evaporated or quickly get concentrated and condense and hence they get transformed very quickly thus for the least amount of time the water molecule is present in the air.
  • The air current picks and drops the molecules to far and distance off place and hence they tend to remove the molecules or shift them from one place to another.

Angiosperms _____. have flowers have cones are nonvascular are seedless

Answers


Angiosperms have flowers.

Angiosperms are plants which produce flowers and are thus commonly referred to as the flowering plants.

All angiosperms  produce flowers at some stage in their life. Flowers are important to the angiosperms  because they serve as the reproductive organ for the plant, providing a means for the plant to propagate itself. 

Angiosperms are the largest group of plants on earth. They account for approximately 80% of all known living plants. There are about 270,000 known species of angiosperms that live on the earth today.

How does a frogs tympanic membrane work

Answers

It works just like a human tympannic membrane. They hear sounds through this structure as sound waves vibrate against the membrane. The men rane acts like a drum skin.
A frogs tympanic membrane, or tympanum, is the circular patch of skin directly behind its eye that we commonly call its eardrum. It functions much like our eardrum does - the tympanum transmits sound waves to the middle and inner ear, allowing a frog to hear both in the air and below water. 

Which mechanism do sponges possess that makes a predator think twice before attacking it?

Answers

Answer:

Sponges come under phylum Porifera. They exhibit cellular levels of body organization and are inactive in nature. The sponges are known to generate and discharge some kind of toxins. The discharging of the toxins may perform various activities like shielding themselves against the parasites and predators. However, these toxins are also considered to harm other sponges.  

This mechanism of sponges makes a predator think two times before attacking it. The sponge will generate toxins, which could disorder the metabolism of any species that try to eat them. However, the majority of the predators possess the tendency to detect the toxin via their sense of smell, and thus, helps them in avoiding the sponges.  
Sponges possess the defense mechanism of releasing toxins that make a predator
