Regulation of opening and closing of stomata
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.
The Spanish scientist should bear in mind that the production of eggs of salmon is dependent on lots of factors apart from the temperature. These factors include type of water, nutrients, etc. If these factors are also set constant then, the scientist can expect the same result from his friend.
Answer:
CAAGGUCUC
Explanation:
In an RNA strand, the bases would be Thymine, Uracil, Guanine and Cytosine.
The difference in the bases between DNA and RNA is that in RNA the complementary base of thymine is uracil, but in DNA the complementary base of thymine is adenine.
