Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis
The answer your looking for is B different patterns of gene expression
The question is not clear
Answer:
The correct answer would be - 1. group 2.period 3. less 4. more
Explanation:
elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.
At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.
Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.
As most responsive metals are put on the left half of occasional table.
Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.
<span>Evidence about ancient climates indicates that
</span>glacial ice once covered much of what is now India and Australia
There was once glacial where these countries are located now due to heat it all melts
so correct option is A
hope it helps
