The answer that fits the blank provided above is STEROIDS. Steroids are fat-soluble signal molecules. This is one of the derivative compounds of cholesterol along with Vitamin D and bile salts. All steroid hormones are considered as a derivative of cholesterol. The answer for this would be option D.
Speciation, the evolutionary process by which new species are formed, is clearly responsible for the ultimate generation of species diversity over geologic time.
Genotype. A human being's genome is made up of approximately 3 billion base pairs which make up about 2000 genes. Individuals, however, differ slightly in the sequence of their DNA in some regions. This unique genome identity is the indivudual genotype. Sequence of DNA in a genome can nowadays be determined through sequencing using Next Generation Sequencing machines
Explanation:
Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ... Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.
Photosynthetic plants use carbon dioxide to generate and function. Plants need energy (glucose) to survive. They exist to absorb carbon dioxide from the atmosphere. One of their end products is oxygen. Animals take in oxygen and release carbon dioxide while the plants take in carbon dioxide and release oxygen. This is balance.
