Balthazar's depression is being treated through a procedure in which electrodes are placed on both sides of his head and a brief current is turned on. the current triggers a seizure that lasts about a minute, causing his body to convulse. his treatment is known as:

The correct answer is electroconvulsive therapy or ECT.

Explanation:

The ECT refers to a medical treatment, which is most generally utilized in patients with bipolar disorder to severe major depression that has not reacted to other treatments. In this method, a brief electrical stimulation of the brain is performed, and the current instigates a seizure, which lasts for a minute, causing the body to tremble.

chlorophyll a: this is the most abundant pigment in plants. chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). it reflects green light strongly so it appears green to us.

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.
