The carbon footprint can be decreased by a great amount if the incandescent bulbs are replaced with the compact fluorescent bulbs. The compact fluorescent bulbs uses approximately seventy five percent less energy than the incandescent bulbs as they do not use heating mechanism to light. This leads  to less emission of the green house gases and thereby reducing the carbon footprint.

Hence, the correct answer is 'option a - replacing incandescent bulbs with compact fluorescent bulbs'.

After the energy crisis of the 1970’s and the OPEC oil embargo, the US _______.
Anastaziya [24]

The Americans resorted to energy and gas-saving measures to cope with the embargo and the high price of oil.  The competition posed by non-OPEC members also contributed to the drop in oil prices and this affected the Arab economy who also took up austerity approaches to address the matter.  The prices of oil later stabilized in the 1980s.

k0ka [10]

Answer:

True

Explanation:

The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by  via impulses transmitted through the sympathetic nervous system, and also secondarily  through catecholamines secreted from the adrenal medulla.

Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.

DOMAINS AND KINGDOMS
iVinArrow [24]
For the first question, a unicellular eukaryote with autotrophic features (meaning it can produce its own food) will be from either Domain Bacteria and Domain Eukarya, but since Domain Bacteria is not in the choices, then Domain Eukarya is the answer. Domain Archaea are yes, unicellular organisms, but they are not eukaryotes and they do not possess autotrophic features. Domain Eukarya have photosynthetic protozoans (i.e. Diatoms).

For the second question, in Kingdom Fungi, you chose that fungi can either be unicellular or multicellular, which is true, for instance yeast and mushrooms respectively. Fungi are heterotrophic as they cannot produce their own food. The other answer is that fungi are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.

For the third question, in Kingdom Protista, you chose that protists can either be unicellular or multicellular, and this is true in the case of amoebas and kelp respectively. Protists can be both heterotrophic and autotrophic. The other answer is that protists are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.
