Answer: The correct answer is they form an ionic bond by exchanging an electron.

Explanation: There are 2 types of bond that can be formed between the elements.

1. Ionic bond: These bonds are formed when there is a complete transfer of electrons from one element to another. The element which donates an electron is a n electropositive element and an element which accepts an electrons is an electronegative element.

2. Covalent bond: These bonds are formed when there is sharing of electrons between two elements.

Lithium is the 3rd-element of the periodic table having electronic configuration: $1s^22s^1$

This element can easily loose 1 electron.

Fluorine is the 9th-element of the periodic table having electronic configuration: $1s^22s^22p^5$

This element can easily accept 1 electron.

Hence, these elements form ionic bond because there is complete transfer of electrons from lithium to fluorine. As, only 1 electron is getting transferred from lithium to fluorine. Therefore, the correct answer is they form an ionic bond by exchanging an electron.

What role does cellular respiration play in the carbon cycle

baherus [9]

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Which of the following is a true statement about diffusion?

mafiozo [28]

The correct statement is this one: Molecules move from areas of high concentration to areas of low concentration.

This is true also for diffusion outside of organisms, for example diffusion of gases in a room.

The other options are false.

Consider the levels of organization of the biological world, and place each of these items in order from smallest level of organ

Zina [86]

Answer:

The correct answer will be option-

Hydrogen (atom) →water (molecule)→ liver (organ) →skin (cell) →elephant (organism) → wolf pack (population) → tropical rainforest (ecosystem) →planet Earth (Biosphere).

Explanation:

The biological level of organization is the arrangement of the matter from the smallest to the largest in the hierarchy.

The smallest unit of matter is the atom which forms the molecules. These molecules together form the organelles which aggregate and form the basic unit of life called cell. The cells aggregate-gate and perform the same functions to form tissues which together form the organs. These organs constitute the organ system which forms the organisms. The organism together forms the population which form the community. The community becomes a part of the ecosystem which forms the largest level called the biosphere.

On the basis of this, the given options are arranged.
