energy level which makes them highly reactive with water and halogens.

"These" should be referring to Alkali Metals.

They include metals such as Lithium, Sodium, Potassium etc.
They're classified as Group I elements because they all have one outmost shell electrons. This is why these metals are so reactive because they only need to lose one electron in order to achieve the octet of electrons (or duplet for Lithium), which means complete outmost shell electrons (2 or the 1st shell, others are 8). 

The reason why they're especially reactive to Halogens (Group VII) elements are that Halogens have 7 outmost shell electrons, which only needs one more electron in order to get to the octet of electrons. So, if an Alkali metal reacts with a Halogen, the metal would give one of their electrons to the Halogen, that way, both of the elements can have an octet of electrons (or duplet).

On which of these issues is public opinion less likely to affect policymaking?
11Alexandr11 [23.1K]

Public opinion is less likely to affect fiscal policy making.

There are a number of variables that affect the formulation of a country's fiscal policies, the most important being domestic demand and economic growth.

Public opinion is therefore not a relevant factor that affects the formulation of these policies, it affects more social and environmental policies, for example.

For a better understanding of fiscal policy, we must understand the concept of taxation.

Taxation is a financial obligation on individuals and organizations, whose main objective is to improve the economy and public services so that there is a fairer and more equal society.

Some examples of taxes:

  • Income tax
  • payroll tax
  • sales tax

Therefore, public opinion is more likely to affect the formulation of social and environmental policies than fiscal policies. Because it is capable of instituting new ideas and social awareness that can directly affect legislation.

What is the essence of the catalase test?
garik1379 [7]

Explanation:

Catalase test demonstrate the presence of an enzyme called catalase, that catalyses the release of oxygen from hydrogen peroxide. It is used to tell the difference between the non-catalase producing bacteria from those bacteria that produces an enzyme catalase. Catalase is produced by the bacteria that respire using oxygen. If an organism produces catalase, bubbles of oxygen are produced when hydrogen peroxide is added to it.

Cardinal flower has scentless, bright red flowers that are long and tubular. What is the most likely pollinator of this plant?
Bond [772]

Answer:

Hummingbird

Explanation:

Pollination is the process by which pollen grains are transferred from anther of a flower to stigma. It is a vital process required for reproduction of new plants.

Cardinal flower has two upper petals and three lower spreading petals. All the petals combine to form a tube at the base. Hence the flowers get a tubular shape. Insects can not enter the tubular flower easily so humming birds usually pollinate these flowers. The hummingbirds feeds on its nectar and pollinates the flower in the process.
