lys-0071 [83]

Answer:

the size of Ca is the greatest ,then Mg is the greater on size than Be

Explanation:

if you make the  electron configuration for each of the elements, what  is the main  difference  u gonna see ?

Be 4   1s2/2s2

Mg 12 1s2 /2s2 2p6/3s2

Ca 20 1s2 /2s2 2p6/3s2 3p6 3d/4s2

see that all the elements are in the same group but are in different period

u gonna see the last electron valance shell in Ca are too far  from its nucleus but in  Be the last electrons are too close and more attracted to the atom's nucleus , so the size of Ca is the biggest then Mg then Be

Compare and contrast cytokines in animal and plant cells
GarryVolchara [31]
<h3>Answer:</h3>

Cytokinesis in animal cells occur by cleavage while in plants it occurs through the formation of a cell plate.  

<h3>Explanation:</h3>
  • Cytokinesis refers to the process through which the cytoplasm divide in animal and plant cells.
  • It occurs after the division of the nucleus.
  • Cytokinesis in animal cells differs from that in plant cells in that, in animal cells it occurs by cleavage while in plant cells cytokinesis occurs through the formation of a cell plate.
  • In animal cells, cleavage occurs as a result of the activity of actin and myosin which results to dividing of cytoplasm in to two.
  • In plant cells, cell plate is formed by the fusion of golgi bodies on the equator which will generate cell wall and the plasma membrane between daughter cells.

Is there energy available to transfer to the surroundings when bonds break? Justify your answer
storchak [24]

There is no energy available to transfer to the surroundings when bonds break as it's an endothermic reaction.

<h3>What is Endothermic reaction?</h3>

This is the type of reaction in which heat is absorbed from the surrounding and is involved in the breaking of bonds.

There is no energy available to transfer to the surroundings when bonds break because it's needed in the conversion of the reactant to product in a chemical reaction.
