Empirical evidence, also known as sense experience, is the knowledge or source of knowledge acquired by means of the senses, particularly by observation and experimentation.
We rely upon all parts of our bodies when gathering empirical evidence but we mostly rely on our brains to process the information that becomes the empirical evidence. To be more specific, we use our nervous system which is divided into central nervous system (brain, spinal cord) and the peripheral nervous system (mainly consists pf nerves) which are long fibres or axons that connect CNS to all parts of the body.
<span>The precision of scientific calculations is limited by the measurement that's the least precise out of all the measurements used in the calculation. When considering significant figures, the last answer should have the least significant figures out of all the measurements that entered into account and were able to be done with the most significant figures that could be directly measured. So, as more precise we are in measurements, more precise can be the final answer to a scientific calculation.</span>
The release of calcium ions initiates muscle contractions. ... The contraction of a striated muscle fiber occurs as the sarcomeres, linearly arranged within myofibrils, shorten as myosin heads pull on the actin filaments.
Answer:
Prokaryote: lack of membrane-bound nucleus, DNA in cytoplasm, single circular chromosome
Eukaryote: Membrabe-bound nucleus, DNA inside nucleus, multiple chromosome.
Explanation:
Prokaryotes are one of the two domains, which consists of organisms that do not possess a membrane-bound nucleus. Due to this fact, the genetic material (DNA) of prokaryotic organisms like bacteria is found located in their cytoplasm. The DNA is found as a single circular chromosome in a region called NUCLEOID.
On the contrary, eukaryotes are the second domains of organism characterized by their possession of a membrane-bound nucleus that houses their genetic material (DNA). All the DNA of an eukaryotic organism like plants, animals etc. are found inside its NUCLEUS. They are made up of multiple linear chromosomes.
