Answer:

A cell is the smallest unit of life.

Explanation:

Cell is the smallest and basic unit of all living organisms. Some organisms are unicellular i. e. made of one cell and some organisms are multicellular i. e. made of more than one cell. In Unicellular organisms, single cell perform all functions and activities of the cell such as excretion, reproduction and digestion etc, while in multicellular organisms, there are specific cells for each activity.

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.

Explain how primate hand features increase fitness and give one example. When writing about your example name the hand feature t
zalisa [80]

Answer:

Explanation:

The primates have a hand feature which increases their fitness in the tree environment are the opposable thumbs. The thumbs are the broadest digit of the hand. The thumb can move in different directions in comparison to the other digits of the hand. This is an advantage in primates to hold and grasp the objects with their hands.

The monkeys climbing on the trees grasp the branches of trees to move from one tree to another.
