Answer:

Coelom

Explanation:

The extensive body cavity (coelom) is modified to form several specialized regions. Two subdivisions of the coelom are the perivisceral coelom and the water-vascular system.

What structure holds the two sister chromatids together as they prepare for cell division.
otez555 [7]

Two sister chromatids are held together by the centromere

<h3>The Chromosome</h3>

The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.

Each of the sister chromatids carries an allele of the same gene.

The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

Which mutations is most likely to cause a phenotypic change?
melomori [17]

The question is incomplete. The complete question is as follows:

Which of the following mutations is most likely to cause a phenotypic change?

A) a duplication of all or most introns

B) a large inversion whose ends are each in intergenic regions

C) a nucleotide substitution in an exon coding for a transmembrane domain

D) a single nucleotide deletion in an exon coding for an active site

E) a frameshift mutation one codon away from the 3' end of the nontemplate strand

Answer: D) a single nucleotide deletion in an exon coding for an active site

Explanation:

Deletion or insertion of a single nucleotide in an axon coding for an active site is called frameshift mutation.

The sequence of codons is read during translation, in order to synthesize a amino acids chain and form a protein from the nucleotide sequence. Frameshift mutations occur when the usual codon sequence is broken by the deletion or addition of one or more nucleotides. For example, if only one nucleotide is removed from the axon sequence during the RNA splicing process, then there will be a disrupted reading frame for all codons before and after the mutation. This may result in several incorrect amino acids being introduced into the protein. Disruption in protein sequence will cause phenotypic change.

Hence, the correct option is D) a single nucleotide deletion in an exon coding for an active site .

Answer:

coarse-grained

Explanation:

Intrusive rocks have a coarse grained texture. Extrusive Igneous Rocks: Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface. These are the rocks that form at erupting volcanoes and oozing fissures.
