Answer:

Embryological evidence

Explanation:

Deuterostomes is a group that includes echinoderms, hemichordates, and chordates. Although these animals exhibit a wide variety of body plans, they share a mouth secondarily formed during embryo development, which it is believed to be an evolutionarily derived character present between a common ancestor and all its descendants (i.e., a synapomorphy). This oral cavity is formed by the invagination of the ectoderm layer opposite to the blastopore of the gastrula.

Use the drop-down menus to complete each sentence.
suter [353]

Answer:

The correct answer would be - 1. group 2.period 3. less 4. more

Explanation:

elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.  

At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.  

Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.  

As most responsive metals are put on the left half of occasional table.  

Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.
