Answer:
There is a positive relationship between environmental policies and jobs and the economy.
Explanation:
The conclusion of the studies is that environmental policies increase employment in the industrial sector. It is because for reducing pollution, the industries does not use heavy machinery for increasing production so these industries uses labour to maintain its production capacity and for more production more labour is required which decrease the problem of unemployment while economy also increases due to more production of products in the industries.
You can carry out a test ,
1- take a sample of the air in a test tube
2-add limewater to the test tube
3- result : if it turns milky/cloudy it has microorganisms
4- reason: because every microorganism respires , and so it produces Carbon dioxide .
and limewater is the test to show the presence of Carbon dioxide .
Cells don't grow very big because they have to be able to diffuse through material easily. Also, when cells are small and plentiful they are easy to replace when damaged.
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.
