Explanation:
Infrared, is much more different compared to Bluetooth and WiFi. Infrared uses, as the name infers… the infrared spectrum of light. It is basically red light which is not visible to our human eyes. Unlike radio waves, infrared cannot pass through walls and other obstructions, so the applications are usually limited to devices that are within Line-Of-Sight or where light can travel
Much of the coordination of vertebrate body functions via chemical signals is accomplished by the endocrine system.
The endocrine system is an information system composed of hormonal feedback loops that are secreted directly into the circulatory system by the body's endocrine glands and regulate distant target organs.
In vertebrates, the hypothalamus is the centre of neuromodulation of all endocrine systems. The main endocrine glands in humans are the thyroid and adrenal glands.
The study of the endocrine system and its disorders is called endocrinology.
The glands that send signals to each other in sequence are often referred to as the hypothalamic-pituitary-adrenal axis.
In addition to the specialized endocrine organs mentioned above, many other organs that are part of other body systems have secondary endocrine functions such as bones, kidneys, liver, heart and gonads.
For example, the kidneys secrete the endocrine hormone erythropoietin. Hormones are amino acid complexes, steroids, eicosanoids, leukotrienes, or prostaglandins.

C. During prophase I, SEGMENTS of chromatids are exchanged between homologous chromosomes.
The efferent (efferent means outgoing) arterioles are the blood vessels, which carry the blood away from the glomerulus. From the anastomotic capillaries into the cortex, which are also known as peritubular plexus the efferent arterioles bring the blood to the capillaries present in the medulla or vasa recta.
Hence, the correct answer is efferent arterioles.
An animal body plan that is triploblastic and coelomate has three main layers of tissue during development.
<span>The germ layers are tissue layers which develop early in embryonic life, through the process of gastrulation. During gastrulation, a hollow cluster of cells-blastula reorganizes into two primary germ layers: an inner layer- endoderm, and an outer layer, - ectoderm which interact to produce a third germ layer - mesoderm. Together, the three germ layers will give rise to every organ in the body. For example, ectoderm will form skin, endoderm will form digestive tract and mesoderm will be involved in the formation of visceral organs like the stomach.</span>
