1) Interphase is the longest phase and most of the cells are present in that very stage !!
2) Interphase is the longest phase and Anaphase is the shortest phase !! Interphase is the longest phase as in this phase the cells prepare themselves for dividing and it takes most of the time for gathering energy for division ; in this phase DNA also replicate !!
3)
Interphase: DNA replicates;
Prophase: Nuclear membrane starts disappearing and Centrioles go on opposite poles !! DNA condense to form Chromosome.
Metaphase: Chromosome attach to spindle fibre and starts to move to equitorial plate.
Anaphase: Centromere divide and half the chromatid goes on either pole
Telophase: Nuclear membrane starts to reassemble; Chrmosome goes to normal uncoiled state ; Other organelles starts appearing
Cytokinesis: Cell furrow forms and cell divides into two half.
4) In dividing cell nucleus membrane is absent while in non dividing cell the membrane is intact
5) Tip of the onion root is meristamatic cell which divides but if it is permanent cell ; there would be no division !!
Answer:
The correct answer is - observation.
Explanation:
Scientists like Si-Ling Chi, Aristotle, and Mary Anning developed various scientific processes and made discoveries that shaped the history of the world. such discoveries are discoveries related to silkworms and how to make cloth from their cocoons by Si-Ling Chi, developing the scientific method by Aristotle and Contribution to the field of paleontology greatly by Mary Anning.
All these scientists had a different type of skill and ability and one of the skills they had a strong power of observing the things or phenomenon work and many more other aspects of the scientific process.
Answer:
Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.
Explanation:
Rutherford concluded from his experiment that there are empty spaces present in most parts of the atom while a heavy positive charge is present in the nucleus of an atom due to which the tiny positively charged particles deflects because of positive-positive charge repulsion. Most of positively charged particles passes undeflected which indicated the presence of empty spaces in the atoms. The electrons revolve around the nucleus have no effect on the deflection of positively charged particles.
In this
case, when Alicia is being tickled by her older sister, the divisions of
the nervous system which are responsible for receiving the signals from her
sister’s fingers are called somatosensory cortex and anterior
cingulated cortex nervous system.
When you are touched lightly, the effect of having that ticklish
sensation is caused by the analysis of two regions of the brain. For example,
when our brain analyses the pressure of the touch, this is the work of
the somatosensory cortex. On the other hand, as
soon as something touches your skin, the signal sent from the skin's sensory
receptors also passes through the anterior cingulated cortex.<span>This is
where the pleasant feelings are governed. </span>
