Answer:

Adding fluoride to the water supply reduces the incidence of tooth decay. Fluoride protects teeth from decay by demineralization and remineralization. Too much fluoride can lead to dental fluorosis or skeletal fluorosis, which can damage bones and joints.

if you had to explain to someone the difference between heat and temperature, how could you use one of the following to demonstr
Rainbow [258]

Answer:

We associate paper money or points in video games, as molecules that make a heat transfer or an increasin in its temperature.

Explanation:

The meaning of heat is associated with an energy transfer, where for example if we put a spoon in a cup of hot drink, the drink will be transferring heat to the spoon. It is a transfer of energy between two bodies due to a difference between their temperatures.

Temperature is associated with the movement of kinetic energy of the molecules. When the temperature is higher, the kinetic energy is higher, so as more detained they are, temperature will be lower.

If we take paper money as molecules, the greater movement of money explains that we have an increase in temperature (we would be hot), even if we think of video games, for example gambling where as more points we gain, we generate an increase in the movement of "molecules".

When we use paper money to buy something we are doing a heat transfer.

We can associate terms to the Thermodynamic where

Heat = Internal energy + work

For clearance would be

Internal energy = Heat - Work

The money we use less the work we do keeps our internal energy. If in a gambling video game, we earn points over and over again, when withdrawing the prize we perform "heat transfer".

How do cells reproduce? ∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵
lora16 [44]

Answer:

Cells divide to reproduce. There are two primary methods used, one for somatic cells, which compose the organism’s body, and one for reproductive cells, or gametes.

Scientists call the process of somatic cell division mitosis. Mitosis has six distinct steps in which the cell organizes and copies the DNA in the nucleus. Once copied, each new cell has its own copy of the DNA. The six steps of mitosis are prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Some authorities consider the non-dividing portion of the cell’s lifecycle, known as interphase, to be one of seven steps involved in mitosis; however, interphase cells are not actively dividing.

Sex cells, such as sperm or eggs, must divide differently. Sex cells only possess one-half of the DNA that makes up a new animal. That way, when they combine, the resulting organism gets half of its DNA from its mother and half from its father. Because sex cells only want half of the DNA in each cell, they go through a different division process called meiosis. In meiosis, the cells split a second time, which yields four daughter cells rather than two as with mitosis; however, this provides each daughter cell with 23 chromosomes in contrast to the 46 chromosomes in somatic cells.
