Answer:
When we observe the position of a star its position changes over the course of a year. It will return to the same position a year after the first measurement. This effectively proves that the Earth is in orbit.

The pesticide is sprayed, and only those that can withstand it survive while the others perish. Those who can withstand it generate offspring who can withstand it.
Pesticides have the potential to pollute lawn, water, as well as other vegetation. Herbicides can be poisonous to a variety of different organisms in contrast to insects and plants, such as birds, fish, helpful invertebrates, and quasi plants. staying inside the rooms where bug sprays are being used or bringing inside household items designed for the outdoors.
Pesticides have the potential to pollute turf, water, soil, and other plant life. In addition to destroying weeds or insects, pesticides can be poisonous to a variety of other animals and plants, including fish, birds, beneficial insects, and non-target plants. residing in the areas where foggers are utilized or bringing indoor-use items inside your home. Any substance "designed for avoiding, eliminating, repelling, or reducing any pest" is referred to as a pesticide.

During embryonic development of animals, tissue layers form. This process of embryonic tissue development is called Gastrulation.
A sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. By contrast, the second electron resides in the deeper second electron shell, and the second ionization energy required for its removal is much larger: +4562.4 kJ per mole. Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet.
Answer : According to the octet rule, sodium wants to lose an electron.
Explanation :
The given element is sodium with atomic number 11 that means it has 11 electrons.
The electronic configuration of sodium will be,
From the electronic configuration, we see that one electron of sodium present in its outer energy level. Sodium can be lose one electron easily for the stable electronic configuration.
According to the octet rule, sodium has the tendency to lose one electron and form positive ion with the charge (+1).
Hence, according to the octet rule, sodium wants to lose an electron.
