If you were 6’6 1/2 tall, about how many meters tall would you be
Luden [163]

Answer:

1.99metres

Explanation:

Foot and inches are measurements of heights. A height measurement of 6’6 1/2" means I am 6 foot and 6.5 inches tall.

Firstly, we need to convert the foot and inches measurement to all foot.

Since 1 foot = 12 inches

Then, the 6.5 inches is 6.5/12

= 0.5416foot

We add this to the existing feet measurement, i.e. 6 foot + 0.5416 foot

= 6.5416 foot.

Hence, 6'6.5" means 6.5416'

Now, we convert the foot measurement to metres.

1 foot makes 30.48 cm

Since 100 cm makes 1 m

30.48 cm will be 30.48/100= 0.3048m

Hence, 1 foot = 0.3048m

6.5416 foot = 6.5416 × 0.3048 m

= 1.9938

Therefore, a height measurement of 6’6 1/2" is 1.99 metres tall.

There is a block of genes in the order ABCDEFG on a chromosome. A duplication takes place between, but not including, genes B an
anastassius [24]

Explanation:

ABCDECDEFG

Duplications involve the production of one or multiple copies of a specified region of the genetic code

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly condensed and wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.

Duplications involve the production of one or multiple copies of a specified region of the genetic code.

Like other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This  variation refers to the genetic characteristics present within a species. Mutations are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage.
