मानव द्वारा उपयोग किए जाने वाले चार विभिन्न प्राथमिक ऊर्जा संसाधनों की सूची बनाएं
<em><u>Crude oil, coal, wind and natural gas are all primary energy sources. Electricity is not a primary energy source, it's an energy currency (see electricity as an energy currency for an in depth discussion). Likewise, secondary fuels are also energy currencies and aren't primary energy sources, they must be made.</u></em>
Because as humans grow bigger, so does there brain. So the smaller you are, the smaller your brain.

Answer:
A) the concentration of calcium ions in the sarcoplasm of a resting muscle
Explanation:
Sarcoplasmic reticulum is a system of the membranous sac that is present around each myofibril and is filled with calcium ions. When muscles are in the resting stage, calcium ions are stored in the sarcoplasmic reticulum.
As the muscle action potential triggers change in voltage-gated calcium ion channels of the sarcoplasmic reticulum, the channels are opened to release the calcium ions in the sarcoplasm. Increased calcium ion levels in sarcoplasm make the muscle fibers to contract.
Removal of acetylcholine from the synaptic cleft ends the production of muscle action potential and calcium ions are moved back from the sarcoplasmic reticulum.
Hence, lower levels of calcium ions are maintained in sarcoplasm when the muscles are in the resting stage.
Answer:
C. fungus-like protist
Explanation:
The fungus-like protists are organisms that seem like plants, but are much more closely related to the animals. They tend to be parasitic, thus they use a host in order to be able to get the needed nutrition. Unlike the producers, the fungus-like protists are not capable of performing the process of photosynthesis, thus they do not produce their own food. Considering these characteristics, it is no wonder that they can mostly be found on dead plants from which they can feed upon.
