Place the following in correct sequence from simplest to most complex: 1. molecules 2. atoms 3. tissues 4. cells 5. organs

Lera25 [3.4K]

Answer:

Simplest to complex

Atoms, molecules, cells, tissues, organs

Explanation:

An atom is the smallest or basic unit of any substance or thing. therefore, it is simplest among given.

Two or more atoms joined together to form molecules. Therefore, molecules are complex than atoms.

Cell is the basic unit of life and a cell is made of many molecules and compounds. So, cells are more complex than molecules.

Several cells organised in a definite way to form tissue, so tissues are group of cells and perform a definite function inside a living thing. So, tissues are more complex than cell.

Organs consist of several cells and tissues and perform a specific functions. Therefore, organs are the most complex structure among given.

Therefore order from simplest to complex is as follows:

Atoms, molecules, cells, tissues, organs

Which of the following is false about a neutral atom of hydrogen?

Nesterboy [21]

Answer: Option (C) is the correct answer.

Explanation:

A neutral hydrogen atom is defined as the atom in which electrons are resent in their ground state only.

Basically in a neutral atom electrons are present in their parent shell.

For example, atomic number of hydrogen is 1 and electronic configuration of a neutral atom of hydrogen is $1s^{1}$ .

Hence, it means there is only one electron present in its valence shell. So, in order to attain stability it will readily react with another atom to gain or share an electron.

Thus, we can conclude that the statement it is less chemically reactive than an atom of aluminum (Al), is false.

Which of the following will likely result in a misfolded protein (mark all that apply)?

Anna007 [38]

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Below are the choice that should accompanied your question above:

<span>1) Mutation resulting in aberrant STOP codon
2) Mutation in DNA sequence
3) Mutation in splice site
4) Mutation in promoter

I think the answer should be

</span>1) Mutation resulting in aberrant STOP codon
2) Mutation in DNA sequence
