Answer:
gymnosperms produce male cones and female cones, and the pollen from a male cone fertilize the egg inside a female cone
Answer:
3) B
4) A
5) B
Explanation:
3) Sun heats up the air of a particular region due to which the air heated rises up ( as hot air is lighter than cool air ). When the hot sir rises , the cool air from other region comes there & like this wind blow.
4) A toaster uses electricity to produce heat in order to toast bread So here the electric energy is converted to thermal energy.
5) Windmills , Hydroelectricity dams & Ethanol plants have turbines & turbines do have a generator which is to be rotated . When the generator is rotated , electricity is generated.
Answer:
Due to the earth spherical shape, different latitudes of the planet receive varying solar energy levels from the sun. This is due to the differences in how the sun rays hit the earth surfaces and differences in the length of atmosphere the rays have to travel before they reach the earth's surface.
The equatorial regions get the most energy levels from the sun hence their atmosphere gets heated faster and the hottest. The air mass in this latitude, therefore, gets less fast dense and begins to rise. The cooler and denser air mass from the poles rushes in, through the lower atmosphere, to replace the void of the rising air.
When this air mass also gets heated, it too begins to rise. Remember the initial air mass cooled as it rose into the upper atmosphere. This now makes it denser than the air mas below it. As the hotter air mass begins to rise from below it pushes the cooler air mass above laterally. After the lateral movement, the air mass begins to sink slowly as it moves towards the poles because the incoming air mass gets denser than the local air mass.
The lateral movement of the convection current moving to the north is deflected to the north-west due to the Coriolis effect of the earth rotation while the lateral movement of the convection current moving south is deflected to the south-west. These pockets of convection currents are called Hadley cells.

Answer:
<u>Basal cells</u>
Basal cells divide faster than needed to replenish the cells being shed, and with each division both of the two newly formed cells will often retain the capacity to divide, leading to an increased number of dividing cells.
Im srry if its wrong :(
Answer:
Yes
Explanation:
Mycorrhizal network. Mycorrhizal networks (also known as common mycorrhizal networks or CMN) are underground hyphal networks created by mycorrhizal fungi that connect individual plants together and transfer water, carbon, nitrogen, and other nutrients and minerals.
