Proteins and carbs known as glycoproteins on the outside of a cell are used in cell signaling, the immune system, and even reproduction. Glycoproteins are very important in the body!
The moments of energy and nutrients through living systems are different because
The movements of energy and nutrients through living systems are different because (1 point) energy flows in one direction, and nutrients recycle. energy is limited in the biosphere, and nutrients are always available.
Answer:
Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. As species become extinct, the variety of species in the biosphere decreases, which decreases biodiversity, Every organism plays an important role in the ecosystem to which it belongs.
Explanation:
One way would be to administer an IQ and then compare the results to other age group averages to determine a relative mental age.
Answer:
Answer B. Endosymbiosis
Explanation:
Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.
