Hypothesize why only one genus and species remains in the hominin group
laiz [17]
<span>Modern humans have been around for a very short period of time. There are differences in race, asian people tend to be smaller, stuff like that. The problem is different races marry and those genes mix. If Asians only married pure blood Asians, Africans only married and procreated with other Africans thanks in hundreds of thousands of years different sub species would most likely start to occur. Seeing as how human population is all connected today, that won't happen.</span>

Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as monohybr
Mademuasel [1]
Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring.  True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.

As we know three most common house hold fuse value sare 3A,5A and 13A.
Reptile [31]

The list of household electrical appliances categorized according to their power consumption and what fuse they will use are:

<u>3A Fuse </u>

  • A table lamp,
  • Computer
  • Blender,
  • Refrigerator  
  • Deep freezer etc.

For every appliance that is rated between 700 and 3000 watts, it's plug should have a 13-amp fuse installed onto it.

<h3>What is a fuse value?</h3>

A fuse rating is the amount of current required to blow (break) the fuse. When a fuse blows, it disconnects power from an electrical system.

The fuse rating is generally printed on the fuse itself. The fuse rating is often expressed in 'amps,' which is the standard measurement for electrical current.

<h3>Why are electrical fuses important?</h3>

If an appliance malfunction results in an excessive current flow, the fuse shuts off the circuit.

If something goes wrong, this safeguards both the wiring and the appliance. A wire that melts easily is within the fuse.

How is energy from flowing water different from iron,petroleum or coal ?
Sati [7]
The energy produced from flow of water or "Hydro-power" is different to energy produced from iron, petroleum and coal as it is a clean and renewable form of energy. Hydro-power is derived from the kinetic energy of the natural flow of water like in the case of a water mill whereas the other forms listed require combustion of the fuel source that produces harmful gases leaving a negative impact on the environment. Also, hydro-power is one of the cheapest forms of energy production.  
However, it should be noted that large-scale production of electrical energy from flowing water known as "Hydroelectric Power" uses man-made dams to store water in lakes as a source of potential energy. These dams can also have a negative impact on the environment as the natural flow of water is restricted. Some scientists also suggest that the construction of a dam leads to an increase in the number of earthquakes in and around the area of construction.
