Two chromosomes have the following segments, where - represents the centromere: K L M • N O P Q R S T U V • W X Y Z What type of chromosome mutation would result in the following chromosomes? K L M • N O P Q R S T U V • W Z

deletion

Explanation:

The type of chromosome mutation that will make the chromosome segment  K L M • N O P Q R S T U V • W X Y Z  to become K L M • N O P Q R S T U V • W Z is deletion of nucleotide bases.

Mutation is generally defined as a change to the DNA sequence of an organism and this can happen by outright deletion of one or more nucleotide bases, insertion of new bases, inversion of base sequence or substitution of one or more nucleotide bases with another.

Deletion is the outright removal of segments of chromosome or DNA sequence.

In the segment K L M • N O P Q R S T U V • W X Y Z, the removal of the two nucleotides 'XY' will result in the segment K L M • N O P Q R S T U V • W Z.

Hence, the type of chromosomal mutation is deletion of segments.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
