Fossil Fuels, Coal, and Gold
Answer:
Cell
Explanation:
Glial cells and neurons are the two types of cells that make up the nervous system. Four tasks are carried out by glial cells, which make up the nervous system's supporting framework: Give the neurons structural support. protect the neurons. A neuron is a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites. Three components make up neurons (nerve cells), which perform the integration and communication processes. Axon terminals, dendrites, and axons. The cell body, also known as the soma, is their fourth component and is responsible for the fundamental functions of neurons. In the illustration to the right, a "typical" neuron is depicted. The neuron, a specialized cell created to send information to other nerve cells, muscle cells, or gland cells, is the basic functional unit of the brain. Neurons are nervous system cells that communicate information to other nerve, muscle, and gland cells. Axons, dendrites, and a cell body make up the majority of neurons.
Answer:
The wing of butterflies compared to that of birds and bats show <u><em>analogy</em></u>.
Explanation:
In the field of biology, analogy can be described as organisms which might have the same function but different biological origin. As we know, all of the flying animals have wings to fly. But all these organisms might not have a common origin. When comparing bats and birds to butterflies, we can see that butterflies have two pair of wings whereas, bats and birds have a single pair. Also, there are many other differences like the wing of a bird has feathers while butterflies do not have feathers.
The menstrual cycle is governed by hormonal changes. In the follicular phase, an increase amount of estrogen occur, follicles begun developing, and one or two become dominant. After some time, the Lutenizing Hormone increases, causing the follicle to release an ovocyte (ovulation). Progesterone is then produced in large amount resulting in the change of the uterine lining for preparation of the implantation of an embryo to establish pregnancy. If implantation does not happen, Progesterone & Estrogen decreases. <span>The hormone drop causes the uterus to shed its lining in a process termed menstruation</span>
