An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
No change. Change happens only when placed in a culture media.

In the picture attached to this question, the two diagrams above did not show very well but I believe that the first diagram contain four dots, which means that the correct option is A.
Carbon has six electrons, that is why 6 is its atomic number is 6 . In writing electronic configuration, two electrons are usually placed in the most inner shell while the other shells will have 8 electrons each. In the case of carbon which has 6 electrons, only four will remain after 2 electron has been put in its inner shell. Therefore the number of electron in its outermost shell will be four.
Answer:
correct.
Explanation:
cell will proceed to S phase for the duplication of chromosomes.
Explanation:
It's a piece of cake. Here we are provided with the information that a human cell with a chromosome number of 46, undergoes meiosis, what number of chromosomes will be in each daughter cell.
To solve this question first you must be aware about the word meiosis. Meiosis is a type of cell division. It's end product results in the formation of four daughter cells each having half the number of chromosomes as that of the parent cell.
Did you notice? That formed daughter cell will have half the number of chromosomes as that of the parent cell. Hence, 23 chromosomes will be in each daughter cell.
