denis-greek [22]

Answer:

Questions, hypotheses, and ideas should be tested against observable evidence.

Explanation:

Skepticism is extremely important, if not fundamental, in all areas of Science. This attitude is based on the belief that all questions, hypotheses, and ideas should be tested against observable evidence. Moreover, it allows scientists to <u>question and think thoroughly about all possibilities behind a phenomenon, instead of just 'believing' any observation or vague and non-supported reason that explains it.</u>

In addition, it allows researchers to investigate all possibilities and test numerous methodologies to be certain and gather enough evidence to explain this certain phenomenon.

Describe the structure of a neuron. Include the cell body, dendrites, and axon in your description. How does the structure of a
igomit [66]

Answer: A neuron has three main parts: dendrites, an axon, and a cell body or soma , which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.

The axon (tree roots) is the output structure of the neuron; when a neuron wants to talk to another neuron, it sends an electrical message called an action potential throughout the entire axon.

The features of neurons help them to carry out their function efficiently:

they have a long fibre (axon) so they can carry messages up and down the body over long distances

in a stimulated neuron, an electrical nerve impulse passes along the axon

the axon is insulated by a fatty (myelin) sheath - the fatty sheath increases the speed of the nerve impulses along the neuron

at each end of the neuron are tiny branches (dendrons), which branch even further into dendrites - the dendrites receive incoming nerve impulses from other neurons

Explanation:

Hope this is helpful!!

Why o we need a reverse compliment for pcr amplifying?
navik [9.2K]

Solution:

Since, DNA occurs as a double strand where each A is paired with a T and vice versa, and each C is paired with a G and vice versa. The reverse complement of a DNA sequence is formed by reversing the letters, interchanging A and T and interchanging C and G. Thus the reverse complement of ACCTGAG is CTCAGGT.

And DNA has two strands: Forward and reverse. Miseq is the technique to sequence the DNA for various purposes such as mutation detection, important for disease diagnosis. Hence, one need to find the mutations in both strands rather than only the forward to strand, to prevent false positives and other artifacts.  

This is the required answer.
