Explanation:
Fat is stored in adipose tissues. They are mostly found around the internal organs and beneath the skin. The organs are padded and thermal insulation is provided. Fat serves as a form of energy storage.
Explanation:
Atoms having a valence shell containing eight electrons are stable. The propensity of every other atom is to attempt to reach this state. Chemical processes are used to transform atoms into this state when they do not already have 8 electrons in their valence shell. By giving up their valence electrons, metals having one, two, or three can generate positive ions. Their valence shell becomes empty when they lose electrons from it. The following shell is now the valence shell, which has eight electrons. To finish their valence shells, nonmetals like chlorine must gain electrons. By gaining electrons, they change into negative ions. Covalent bonds are created by these positive-negative ions. Additionally, nonmetals create covalent bonds in which atoms exchange valence electrons with one another, increasing the number of valence electrons in each element to eight. Noble gases don't need to conduct any chemical reactions because they already have eight electrons in their outer shell. They are gases with one atom.
Explanation:
Fruit is made up of mature ovaries. The seeds contain the embryo. The fruit has seeds inside of it. The appropriate circumstances allow seeds to sprout.
Explanation:
That was a simple one to make you feel more confident! The cell wall is only found in plant cells and is completely permeable. It encircles the cell and aids in keeping it in shape. Because it is cellulose and extremely hard, it contributes to preserving the cell's turgidity.
Explanation:
This query has to do with evolution. Geographic isolation leads animals to evolve into separate species over time through mutation and genetic drift, a process known as allopatric speciation. Geographic separation does not take place in sympatric speciation. Both processes involve natural selection and mutation.
Explanation:
The unit of charge is coulombs. The rate at which electric charge flows is measured in amperes, the unit of current. Resistance is measured in ohms and voltage in volts.
Explanation:
Isotopes are identical atoms of the same element with different mass numbers. The same atomic number denotes the same number of protons. However, since the mass number is the sum of the number of protons and the number of neutrons, the number of neutrons varies, changing the mass number. Because they have the same atomic number, isotopes exhibit similar chemical characteristics. The difference in mass causes their physical characteristics to differ.
