Answer:

Mitosis, interphase

Explanation :

Mitosis can be described as a process by which a cell replicates and makes two daughter cells. Every cell of the body other then the sex cells replicate by the process of mitosis.

Interphase can be described as a phase in which a cell make copies of its DNA in order for mitosis to begin. This phase has three stages:

G1 phase: The cells grows and produces more organelles and proteins.

G0 phase: This phase occurs when the cell does not have to carry out the process of mitosis.

S phase: the DNA is synthesized and other required machinery for mitosis is made.

G2 phase: The cell goes back to normal size.

Few seeds can be dispersed by more than one method of seed dispersal.’ Explain with suitable examples.

MrMuchimi

Answer:

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.

Gravity: A good example of gravity dispersal is the marigold flower. When they are ready, these seeds drop to the ground.

Wind: There are two types of wind dispersal adaptations, the floaters, and the fliers:

(wind) Floaters: The common dandelion is a good example of this type of seed dispersal.

(wind) Fliers: Maple seeds grow in pairs, but when they are mature, they separate, and a strong wind can pull them from the stem

Ballistic: Some common examples of this type of dispersal are garden peas. When the cells grow older, the result is that the pods break open and twist. This twisting actions pops the seeds lose and pushes them away from the pod.

Water: Coconuts have a husk that surrounds the seed. This husk is very buoyant and a coconut seed can float across hundreds of miles of ocean before washing ashore on a new island to germinate and grow into a tree.

Animals: there are also two types of these, hitchhikers and edibles. Seeds that stick to the outside of animals, or are spread when they go out the other end after being eaten:

Hitchhikers: Some examples are cockleburs and foxtail.

Edibles: These seeds are surrounded by good tasting fruit, like apples and peaches.

18. Penny: Used to measure mineral toughness; Cuprum penny's toughness is 3.

Hand Lens: Could be used to measure the hardness of the mineral; the glass can be used as a scratch platform; it can also be used to test the luster of the mineral tile; the mineral is rubbed in the glass portion of the tile and a powdery strike of the stone is given to distinguish the colour of the rock.

Geological hammer: Used to break down the mineral to assess whether or not it has cleavage, and to detect fractures

Pocketknife: Used to define mineral tenacity; the tenacity of the mineral can be silky, malleable, sectile, elastic, or flexible.

17. Volcanoes are holes or cracks in the lava-flowing crust of the earth. They are normally placed on the borders of tectonic plates as they are created as the plates clash and create gaps. In other words, volcanoes located at convergent-plate boundaries.
