I think at Approximately 7 years the child should be able to use each hand independently. Hand control is the ability by a child to accurately use and manipulate objects, utensils, tools and even finger in isolation for functional tsak performance.
A gamma ray consist of gamma radiation.
Answer :
The animals are categorized into 2 groups - eukaryotes and prokaryotes. The microbes like bacteria are coming under prokaryotes. They are unicellular organisms and without a true nucleus.
Viruses are the connecting link between the living and non - living. They are smaller than bacteria. The microbes less than 100 micrometer can't be seen by the naked eye. They can only visible under a microscope.
Viruses like polio, flu virus sizes are 10nm. But some of the viruses are also less than 10nm. The size of bacteria is 1 micrometer. The viruses are 10 times smaller than the bacteria.
The eukaryotic organisms are more advanced and multicellular. Their cell size is larger than bacteria and viruses. The red blood cells under the light microscope are 8 micrometers. The typical animal cells like sperm are 60 micrometers and a skin cell is 30 micrometers. The plant cell for example pollen is 90 micrometers.
The eukaryotic cells sizes are more than prokaryotes like bacteria.
Answer:
This is the specific heat capacity
Explanation:
The specific heat capacity of water is the quantity of heat energy needed to raise the temperature of 1 g of water by 1 degree.it is due to the aggregation of hydrogen bonding holding water molecules together.
Therefore,large quantity of heat energy is needed to be supplied to raise the temperature of water.
This is an advantage for earth temperature because a significant rise in the earth temperature,would not affect the earth because the ocean would have absorbed the heat.Therefore regulating the earth temperature within the narrow limits
However,during summer little heat is released by the ocean and this cools the earth,this is because the specific heat capacity of the ocean is higher than that of the land,thus as the ocean warms up slowly its warms the earth.
Its ok to use regular ear cleaner if your ear is filthy. I would recommend limiting the use of saline.
