Explanation:
Uses/Advantages of Renewable Energy
It can be used to generate electricity e.g. hydro energy
It is used for cooking at homes e.g. wood/biofuel.
It enables the growth of our crops e.g. solar energy.
It facilitate movement of people and goods from one place to another e.g. fuel, diesel, natural gas.
Renewable energy lasts a life time
Renewable energy is clean and does not cause pollution
Renewable energy is cheap once it is fully installed
Misuses/Disadvantages of Renewable Energy
It can be used to produce nuclear weapons e.g. atomic bomb
It can cause flooding through overflowing of dams
Wind can be disastrous e.g. storms
Answer:
Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughtercells. In plants , this occurs when acell wall forms in between the daughter cells. In animals , this occurs when a cleavage furrow forms.
1.) D- phloem is Bi-directional and can flow upward or downward
2.) C- it transports the water from the roots to the stems and leaves
3.) A- capillary action <span>is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity, so it can flow upward through the tissue
4.) B- It conducts the sugar and other metabolic materials downward from the leaves
5.) A- </span><span>The roots </span>have a type of cell called a root hair cell - these project out from the root into the soil. The water<span> absorbed by the root hair cells passes through the plant in xylem tubes, and eventually reaches the </span>leaves<span>.
6.) A- It transports </span> water<span> from roots to shoot and leaves, but it also transports some </span>nutrients. It is Uni-directional though and can only flow upward.
