Mantle convection describes the movement of the mantle as it transfers heat from the white-hot core to the brittle lithosphere. ... Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.Aug 11, 2015
Cell membrane is a thin line.it controls the movement of materials into and out of the cell. it is partially permeable,that is,it allows only certain materials to pass through.
I presume your question is, how many chromosomes would be found in the resulting daughter cells of meiosis?
If parent cell has 16 chromosomes, the first division in Meiosis of the cell will result in 8 chromosomes, and the second division (I.e. the separation of the sister chromatids of the 8 chromosomes) results in 8 daughter chromosomes.
The number of chromosomes in each cell resulting from meiosis is 8.
Hope this helps! :)
Answer:
The elemental is required in very small amount. (Ans. A)
Explanation:
Trace element is also known as micro-nutrient. It is also defined as any chemical element required by living organisms in a minute or small amounts which is usually part of the vital enzyme (cells produced by catalytic protein).
Exact needs of trace elements vary among species, like commonly required plant trace elements are cooper, zinc, manganese, boron, and molybdenum. Animals commonly required iodine, manganese, and cobalt.
Absence of necessary plant trace elements required by plants in the soil causes deficiency disease, lack of animal trace elements used by animals in the soil may not harm plants, but, animals feeding on those plants develop their deficiency disease.
So, the adjective trace means that the elemental is required in a very small amount.
1.) similar fossils were found on different continents.
2.)the continents seemed to fit together; they were like a spread apart puzzle.
3.)geographical features and mountain ranges lined up with the same rock composition
4.)glacier grooves in rocks led him to trace them out to where they started
