Answer:
<u>True</u>
Explanation:
|ndeed, Psychologist Abraham Maslow's sought to describe hierarchy in which the average (or most) humans place their needs. In other words, he believes we as humans have basic needs which we long to satisfy.
On the ranking or hierarchy, according to Maslow the need humans satisfy first is their physiological need. Here's the full hierarchy:
Physiological Needs
↓
Safety Needs
↓
Love/Belonging Needs
↓
Esteem Needs

Self-Actualization
A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. Robert Hooke was the first Biologist who discovered cells
two types of cell
1) Prokaryotes
2) Eukaryotes
Characteristics of Cells
1) Cells provide structure and support to the body of an organism.
2) The cell interior is organised into different individual organelles surrounded by a separate membrane.
3) The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth
i need more information
sorry
good luck thoooo
1) Chemical reaction
CH3 CH2 OH + O2 ---> CH3COOH + H2O
It is balanced
2) Molar ratios
1 mol CH3 CH2OH : 1 mol O2 : 1 mol CH3COOH : 1 mol H2O
3) Conversion of 7.6 grams of ethanol to moles
Molar mass of CH3CH2OH = 2 * 12g/mol + 6 * 1 g/mol + 16 g/mol = 46 g/mol
moles = mass / molar mass = 7.6 g / 46g/mol = 0.165 mol
4) Use of proportions with the molar ratios:
1mol CH3CH2OH / 1mol O2 = 0.165 mol CH3CH2OH / x => x = 0.165 mol CH3CH2OH.
5) Conversion of 0.165 mol O2 to grams
mass in grams = number of moles * molar mass = 0.165 mol * (2 * 16g/mol)
mass = 5.28 g ≈ 5.3 g
Answer: 5.3 g
Infrared radiation is the only one with wavelengths longer than the wavelengths of visible light. X-rays and gamma rays are known to be shorter than visible wavelengths, and cosmic waves are only high energy particles. I hope this helped. And sorry about the late answer...
