The answer should be all of the above, if it is not then the answer is A dichotomous key can help classify an unknown organism.
Hope this helps, if not, comment below please!!!!
The answer is called respiration. Hope this helps.
I suggest you to provide some options, as it's quite difficult to answer your question. Here is your answer: A long bone is covered externally with a sheath called the
periosteum, whereas the marrow cavity is lined with the <span>
endosteum</span>
. I've attached the illustration to make it clear for you
<span>Segregation
For a trait to show or express itself in an individual it must have two types of the same allele (for example P and p) showing on the chromosomes. The showing of both alleles on an offspring's chromosomes means that both parents have the same trait and that is why there is a chance for an allele to become dominant in other words to express itself in the offspring. However if only one allele is transferred in the genes of the offspring that means that the trait that the allele is responsible for, will remain unexpressed.</span>
Chromosomes exchange genetic material in step 3.
<h3><u>Explanation</u>:</h3>
The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.
The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. The step 3 shows the crossing over of prophase 1 of meiosis I. So, it shows the genetic difference between the offsprings and leads to genetic variation.
