Answer: A,C,D
Explanation:
Element in the same group shared similar chemical behaviour and resemble each other because of the same number of valency electron they have. Example group one element have a valence electron of one.
Because of the same Valency electron they react in a similar way.
Example Group 1 have one valence electron and therefore Ionize readily to form positive electron this occur when they donate their valence electron leading to the formation of electrovalent compounds this is applicable for all group one element. Hence,
Elements in the same group have similar properties and react the same
Also, because element in the same group share the same property in chemical behaviour they are said to belong to one family.
Element in the same group do not have the same energy level because their electron tends to increases down the group and therefore energy level increases and not constant for all elements.
Dear Sappysmith21, each molecule/compound of table sugar has 12 carbons, 22 hydrogens, and 11 oxygens.
The stem is most likely made up of vascular tissues. The main vessels present on vascular tissue are the xylem and phloem. These two tissues work as pipes for the transport of water and nutrients inside the stem. Xylem transports water and some nutrients from the roots. The Phloem <span>transports the soluble organic compounds that were produced during </span>photosynthesis from the leaves, and in the case of the cactus photosynthesis happens on the actual stem,<span> to the rest of the plant.</span>
Cytokineses completes in telophase.
<u>Explanation:</u>
cytokinesis is the process by which the cell cycle takes place by dividing the cytoplasm. In a cell, mitosis is always accompanied by cytokinesis In a typical cell, although in some cells like Drosophila embryosand vertebrate osteoclasts mitosis takes place without the process of cytokinesis. Cytokinesis usually starts in anaphase and completes in telophase, thereby reaching completion and there is a begging of next phase called interphase.
Telophase is the last completed stage of mitosis. The name is derived from latin word telos which means end. At this phase the sister chromatids will be reaching the opposite poles. the dissolution of the kinetochore microtubules and the continuous elongation of the polar microtubules occurs at telophase.
Chemical reactions involve the reactants' undergoing a chemical change to become products.
