Question reformatted:

Circle the word that best completes the statement about cell theory.

6. The cell theory states that:

i. All organisms are made of <em>organelles </em>/ <em>cells</em>.

ii. All existing cells are produced by other <em>living </em>/ <em>dead </em>cells.

iii. The <em>atom </em>/ <em>cell </em>is the most basic unit of life.

7. Cell theory is one of the great unifying theories of <em>biology </em>/ <em>chemistry</em>

Answer:

6. The cell theory states that:

i. All organisms are made of <em>cells</em>.

ii. All existing cells are produced by other <em>living </em>cells.

iii. The <em>cell </em>is the most basic unit of life.

7. Cell theory is one of the great unifying theories of <em>biology </em>

Explanation:

Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.

Which pair of terms could be used to describe the location of the nose when compared to the location of the eyes
stiv31 [10]

The pair of terms used to describe the location of the nose

when compared to the location of the eyes are medial and

inferior.

<h3>What is Location?</h3>

Location refers to the exact position of a particular object or

organism. In humans, location of different parts of the body

varies.

The location of the nose is medial to the eyes which means it is

found in the mid-line region of the eyes. The nose is also

inferior to the eyes as it is found in the lower region of where

the eye is located.

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 .
