. If a substance changes form one phase to another, is it still the same substance?
gladu [14]

Answer:

Yes

Explanation:

A phase change does not change the chemical make-up of a substance.  Phase changes are typically temperature dependent, and change only the movement and physical arrangement of the atoms and molecules in the substance.  Water, for example, is composed of two hydrogen atoms attached to an oxygen atom by covalent bonds.  That stays the same whether the water is solid (ice), liquid (water), or gas (steam).  The chemical structure of water does not change as it goes through the different faces.  It's still water.  What does change is the speed at which the molecules move and how far apart they are as a result.  Water vapor consists of molecules moving quickly and at random.  As temperature drops, water molecules slow down.  Since water is slightly polar, hydrogen bonds form between the molecules bringing them closer together.

Based on these concepts, choose statements that correlate Mendel's four postulates with what is now known about genes, alleles,
Vikentia [17]

Answer:

Explanation:

Mendel four postulate is Principles of Paired Factors, Principle of Dominance, Law of Segregation which is Mendels First Law of Inheritance and Law of Independent Assortment which is Mendel’s Second Law of Inheritance.

The six possible outcome are,

3. Alleles segregate from each other during gamete formation at anaphase I gene assorts independent of each other during gametes formation.

4. Some genes have dominant and recessive alleles. Allele of a gene can either be dominant or recessive in its form

7. Unit factors occur in pairs , allele of a gene occur in pair

Dominant alleles can become codominant alleles during mitosis, when two allele both finds expression in the phenotype of an organism they are codominant

8. One gene pair separates independently from other gene pairs independent assessment of gene.

5. Different gene pairs on nonhomologous chromosomes will separate independently from each other during meiosis.
