Answer:
Burning of woods has a negative impact on the climate.
Explanation:
Burning of woods for heating has a negative impact on our climate because it releases carbondioxide gas which is a greenhouse gas that trapped the reflected solar radiation and leads to global warming. We have to used alternative methods for heating such as electric heater instead of burning of wood which produce no pollution and can fulfill the requirement of heating so from the above discussion we can say that the activity has a negative impact on the environment.
The element selenium has the atomic number of 34 while aluminium has atomic number of 13. The electronic configuration of selenium is 2, 8,18, 6 while that of aluminium is 2, 8, 3. This means that, selenium has six electrons in its outermost shell, this allows selenium to have variety of valence numbers. Aluminium on the other hand has only three electrons in its outermost shell. Aluminium will be more ready than selenium to give away its valence electrons in order to attain the octet form. Selenium belongs to the group VIA while aluminium belongs to group IIIA. The group that an element belongs to determine the number of electron in its outermost shell.<span />
Answer:
when vesicles cluster at the future plane of division
Explanation:
Cytokinesis is the process whereby the cytoplasm of a cell divides into two. This process of cytokinesis occurs after nuclear division i.e. division of the nucleus. However, cytokinesis differs in plant and animal cells.
In plant cells, the separation of the cytoplasm involves the formation of a cell plate. The process begins when a structure called phragmoplasts carry vesicles to the cell plate. In other words, vesicles cluster at the future plane of division (cell plate).
Answer:
B because it's a hypertonic solution... that means it's concentrated so water moves out of the cell into the solution
