The transformer is a static electric machine (because it contains no moving parts) belonging to the broader category of converters. In particular the transformer to convert the parameters of voltage (V symbol unit [V] volts) and current (symbols The unit [A] amperes) input than output, while maintaining constant the amount of power electrical (less the losses due to hysteresis and eddy currents). The transformer is a machine able to operate only in alternating current, because it exploits the principles of electromagnetism linked to variable flows. <span>The transformer has paramount importance in today's world: without it, the electricity transmission grids that connect power plants to millions of homes and industries could not function</span>

Explain how the result of meiosis and cytokinesis affects inherited traits
Anna71 [15]

Answer:

Meiosis is a type of cell division in which a single cell is divided into four daughter cells having half number of chromosome while cytokinesis is the division of cytoplasm.

Meiosis occurs only in sex cells which are responsible for the formation of new organism. Traits are transferred from parents to the offspring through the process of sexual reproduction. In sexual reproduction, sex cells i. e. sperm cells of male fuse with egg cell of female forming a zygote which turns into a new organism and traits are transferred from one generation to another.

Two brothers inherit different sets of alleles from their parents. what effect will they have?
lesya692 [45]
Depending on what trait the alleles carry, the brothers will have a different phenotype and a different genotype.
For example; Eye color. My sister is heterozygous, meaning she has brown eyes. I am homozygous recessive, meaning I have blue(green/hazel) eyes. We both have the same parents, I just happened to inherit both of the recessive eye color alleles from my parents whereas, my sister inherited both the dominant and recessive alleles. 

So, since the brothers inherited different sets of alleles, their genotype for a certain trait will be different.

Explanation:

Slave parents, in turn, sought to instill in their children a sense of loyalty to the slave community as a whole. They taught children to refer to other girls and boys as sister and brother
