Aspaceship is designed to support animal life for a multiyear voyage to the outer planets of the solar system. plants will be grown to provide oxygen and to recycle carbon dioxide.; since the spaceship will be too far from the sun for photosynthesis, an artificial light source will be needed. what wavelengths of light should be used to maximize plant growth with a minimum of energy expenditure? ; a) full-spectrum white light; b) green light; c) a mixture of blue and red light; d) yellow light; e) uv light

Mixture of blue and red light

Explanation:

This wavelength of light will maximize plant growth with minimum of energy expenditure compared to the rest of the options

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
