Only two <span>structures are possible for a square planar molecule with a formula of AX2Y2.
Those two structures are CIS and TRANS structures.
</span>If two groups attached to the carbons of the double bond are on the same side of the double bond, they are considered<span> </span>cis<span> alkene but if they lie on opposite sides of the double bond, they are </span>trans<span> .</span><span>
Hope it helps.</span>

Scientists can determine relatedness amongst organisms via way of means of evaluating partial amino acid sequences. The desk suggests 4 partial amino acid sequences from 4 organisms.
<h3>What is determine relatedness?</h3>
Presently, the maximum customary technique for building phylogenetic timber is a technique referred to as cladistics. This technique kinds organisms into clades, organizations of organisms which are maximum intently associated with every different and the ancestor from which they descended.
Scientists can now decide relatedness via way of means of evaluating the frequency of nucleic acid bases (the G + C content), carry out nucleic acid hybridization to decide the diploma to which DNA sequences are the same, carry out nucleic acid sequencing, or carry out different superior molecular techniques.

Enzymes are not destroyed or altered in chemical reactions therefore can be used more that once.
I believe group of cells working together and or performing the same task can be categorized also as a specialized tissue.
