Answer:

A, B, C and E

Explanation:

A – (True) Gymnosperms can reproduce through the rupture of the pollen sac, releasing innumerable pollen grains, which carried by the wind, can reach the eggs found in female strobiles, this process constitutes the pollination, which in this case occurs through the wind.

B – (True) There are reproductive branches in the modified leaf gymnosperms known as strobiles, in some species strobiles are well developed and known as cones. The seeds are formed on the surface of the cones.

C – (True) Gymnosperms are part of the category of vascular plants, which have sap-carrying vessels, whose main function is the transport of water and nutrients.

D – (False) The seeds of gymnosperms are not protected by fruits, so they are known as "naked seeds".

E – (True) Gymnosperm spores can be produced by both <u>reproductive strobiles</u>. Male strobiles are smaller, male spores are produced inside.

Female strobiles are much larger and are known with pine cones and produce female spores.

4. The water cycle is balanced because
Sergeu [11.5K]

Answer:

hello!

Explanation:

The water cycle is critical not only to weather, but to life on earth.  Rain is necessary for the survival of plants and humans.  

Condensation is necessary for cloud formation.  Evaporation is necessary to cooling and keeping a good balance of water vapor in the air.

The water on Earth now is the same water that’s been on Earth since the beginning.  

What makes that feat possible?  The water cycle.  The water cycle is the process that re-circulates water so we can have bodies of water as well as clouds and precipitation.

The first step of the water cycle is evaporation. About 85% of the water vapor in the air comes from water that evaporated from the oceans.  The other 15% comes from evapotranspiration, which is a catch-all term for water that evaporates from over land.  

This includes water vapor produced by plants during transpiration, water from lakes, streams, puddles and soil moisture, direct evaporation of snow and even water vapor from the breath of animals.  

The second step of the water cycle is condensation. Now that the atmosphere is full of water vapor, that water vapor condenses into water droplets.  Sometimes, like early in the morning, the water vapor condenses on the grass as dew and seeps back into the soil, ready to be evaporated again.  

But most of the water vapor condenses higher up in the air and forms clouds. Once the water droplets are in a cloud, two things can happen.  Either the cloud will dissipate and the water droplets will become vapor again, or the cloud will grow and it will begin to precipitate.

The third and final step of the water cycle is precipitation. Precipitation includes all water that falls from the sky, both in liquid and frozen form, which reaches the ground.  

Once the precipitation makes its way to the ground it can end up soaking into the ground, run off into streams and lakes, become snow cover, be used by plants, be inhaled by animals or fall directly back into the ocean. Then the water cycle can begin again and continue for millions of years to come.

Elanso [62]

Jane Goodall was making observations on chimpanzees.

<u>Explanation: </u> 

Jane Goodall spent years with the chimpanzees of Gombe. It all started when she found a chimp who was hungry and wonderfully used a twig of the branch to take the termites of the tree and feed on it. Goodall was fascinating to see a chimp think and behave like a human.

She observed the animal so closely and took note of each behavior. She was so passionate about the chimps that she overcame all the hurdles to find out the redefined mankind.
