The chemicals of life must have preceded the formation of life on earth. This is especially true in the formation of organic molecules especially DNA and RNA and amino acids. Spontaneous reactions in the oceans from chemicals from methane, water, hydrogen, ammonia, and etcetera, occurred in the waters. Energy from the sun and lightning strikes spurred these spontaneous reactions. These organic compounds in the waters when aggregated underwent formations to form photobionts, the precursors of life.
<span>The littoral is a zone identified in lakes and ponds and is the coldest because it is shallow and lacks nutrients to support life. This is False.</span>
Answer:
The endomembrane system includes the nuclear envelope.
Explanation:
The endomembrane is composed by the endoplasmic reticulum (ER) and the golgi apparatus. Its main function is to synthesize proteins (rough endoplasmic reticulum studded with ribosomes) proteins can also be modified in the ER of pass to the golgi apparatus where they can be modified and sort to be packed in vesicles to be exported to different parts of the body, for example hormones.
the nuclear envelope only holds the DNA and it´s not involved in protein synthesis.
Could u possibly give me any options or is it opionon based. let me know ill answer it in a jiffy:)
A.
Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient.
