Answer:
1. Fluorine (7 electrons) => c. steals 1 electron
2. Calcium (2 electrons) => a. gives away 2 electrons
3. Oxygen (6 electrons) => d. steals 2 electrons
4. Lithium (1 electron) => e. gives away 1 electron
5. Xenon (8 electrons) => b. neither gives away nor steals any electron
Explanation:
Given the following valence electrons of the atoms listed above, each atom can be matched to its corresponding number of electrons it can steal or give away as they form bonds and attain a stable state:
1. Fluorine (7 electrons) => this will steal 1 electron from another atom to attain a stable state when it comes to make the number of electrons 8.
2. Calcium with 2 valence electrons, will give away this 2 electrons in its outer shell to be stable and form bond with another atom that will accept these 2 electrons.
3. Oxygen with 2 valence electrons, will steal 2 electrons to make the electrons in its outer shell 8, as it bonds with another atom to become stable.
4. Lithium will give away 1 electron to become stable when it combines.
5. Xenon with 8 electrons in its outer shell is in a stable state and kind of inert. It doesn't need to receive or steal any electron from or to any other atom in this state.
A very strong relationship. I'll take the easiest example :the bees. They are so important for our planet. Without them, we and all living creatures on earth would be on track to dispariton. Let me explain why. At first, the bees need the nectar from flowers to make honey ( source of food ). As they pollen from flower to flower, they transport pollen on their tiny little legs and in this way, they help the plants to reproduce themselves. If, for some reason, there will be no more bees. Plants and flowers will not thrive, plants will be eaten without having contribued to the productivity of the species and they will go out. No plants, no more veggies or fruits for herbivorous and humans, no more herbivorous no more food for carnivorous, etc. Also, without plants, there will be less oxygen on our planet. Slowly the fauna and flora will die on earth and then it will be our turn. That is why relationships with plants and insects are so important. Plants produce oxygen for all of us and they are a natural and healthy source of food and insects help plants to survive and thus save the species.
Answer:
True.
Explanation:
Almost all organisms have the same codons. These codons make them unique so having the same ones means each organism has a shred of uniqueness.
B. a cell with two distinct nuclei
Telophase is the last phase of mitosis and then cytokinesis
Answer:
Deoxyribonucleic acid (DNA)
Explanation:
the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction
