A class of lipids derived from cholesterol are called steroids.
Steroids are important large class of biological molecules which are significant components of cell membrane and signaling molecules.
The answer is <span>C) crossing over.
</span>The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. If it is known that homologous chromosomes are present only in the meiosis I, it is expected that crossover is occuring meiosis I.<span> Homologous chromosomes pair up in the prophase. Therefore, meiosis prophase I is the phase in which chromosomal crossover occurs. Chromosomal crossover is process that </span>helps make meiotic cells genetically <span>different.</span>
Answer:
Glycolysis is a linear metabolic pathway of enzyme-catalyzed reactions that convert glucose into two molecules of pyruvate in the presence of oxygen or into two molecules of lactate in the absence of oxygen.
Explanation:
Answer:
Let's organize this with the four biomolechules:
-NUCLEIC ACID (Nucleotides, Polynucleotides, Phosphodiester linkages)
-LIPIDS (Fatty acids, Triacylglycerols, Ester linkages)
-PROTEINS (Polypeptides, Pepptide bonds, Aminoacids)
-CARBOHYDRATES (Monosaccharides, Polysaccharides, Glycosidic linkages)
Explanation:
It is your circulatory system that takes nutrients and oxygen to cells and takes CO2 from them
