Answer;
-Elements, that are metallic (metals)
Experiment;
Metallic minerals contain metal in raw form.Metallic minerals occur in rare, naturally formed concentrations known as mineral deposits.These minerals contain metallic bonds.
Metallic bonding result from atomic nuclei and inner filed electron shells in a sea of electrons made up of unbound valence electrons or not equally shared
Metallic bonding yield minerals that are soft, ductile / malleable, highly conductive due to easily mobile electrons - metals, also non-directional bonding produces high crystal symmetry
The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful,Genetic drift<span> can cause big losses of </span>genetic variation for small populations, and A founder effect is an EVOLUTIONARY PROCESS THAT RESULTS FROM A FOUNDING EVENT. They are all similar because they all similar because they all <span>effect result in a small population with a subset of the genetic diversity of the original population. </span>
Through mitosis, daughter cells will maintain 20 chromosomses. Meisosis will create cells with 10 chromosomes.
Answer:
Prokaryotes do not have introns, eukaryotes have introns
Explanation:
Prokaryotes do not have introns, eukaryotes do. Introns are regions of DNA that are transcribed but not part of the final protein. They interrupt exons, which are the coding parts of the gene. These are only present in eukaryotes.
Introns need to be removed before the mRNA can be translated into the protein sequence. This occurs by a process called splicing. The splicing machinery binds the junction between introns and exons and excises the intron. The exons are then fused together to create the mRNA.
Other processing steps occur to the eukaryotic pre mRNA to prevent it from being degraded in the cell. This includes adding a cap to the 5' end of the protein, and adding a poly A tail to the 3' end. One these steps are complete, the eukaryotic mRNA is complete.
The prokaryotic mRNA undergoes transcription and translation simultaneously because it doesn't require these processing steps.
Cell division is when a cell under goes mitosis. Which divides in top to create another cell of the same kind.
In Gamete a haploid germ of either sex unites with the opposite sex to have sex and have a zygote.
