Answer:
. Experimentation is the heart of science. Scientists ask questions, gather evidence, share ideas, and analyze data. In designing an experiment, the specific question (or questions) that the experiment is meant to answer must first be clearly identified.
Explanation:
<span><span>This
is because his hypothesis that an organism can pass on characteristics that it
has acquired during its lifetime to its offspring are not approved or </span>verified.
His hypothesis of the notion of inheritance of acquired traits was supplanted
by Mendelian genetics. Yet, because of the discovery of epigenetics and somatic
hypermutation interest in Lamarckism has continued.</span>
Answer:
1.) neurilemma (option f)
2.) nissil bodies (chromatiophillic substance)
3.) neurofibrilis ( option g)
4.) myelin ( option e)
5.) dendrite ( option d)
6.) collateral ( option c)
7.) astrocytes (option a)
8.) axon ( option b)
9.) Unipolar neuron (option i)
Explanation:
The neurological terms described above are different parts of a nerve cell or neurones. The nerve cells are the basic Structural units of the nervous system. They are highly specialised for transmitting electric impulses. They can also be grouped according to the number of processes they possess, for example, the UNIPOLAR NEURONS( those with one process only). Each neuron, however, is composed of the same basic parts which include:
--> The CELL BODY: they may be angular or oval in shape with a large nucleus and dense granulated cytoplasm. In the cytoplasm, rough Endoplasmic reticulum which contains CHROMATIOPHILLIC SUBSTANCE (nissil bodies) and Golgi apparatus are also seen.Network of threadlike structures known as neurofibrilis are also seen within the cell body and extending into axon.
--> DENDRONS: these are one or more extensions which branches to form many fine dendrites. The DENDRONS carry nerve impulses( action potential) that their dendrites receive to the cell body.
--> AXON: this is a long process which branches at it's free end to end in synaptic knobs. It carries electric impulses away from the cell body. Most times, a substance of Schwann cell known as MYELIN SHEATH which is composed of lipoprotein insulates axons and increases impulse speed.
Answer:
The first blank can be filled with tagging. One of the procedures for studying the movements, biology, and migration of animals is known as tagging of animals. Tagging is utilized to examine the long-range irregular and regular movements of animals and to identify their life-span. All kinds of mollusks, vertebrates, and insects can be tagged.
The second blank can be filled with designate their area as a national park. Designation of the areas as a national park is one of the methods of conserving animals, like a tiger.
