Which of these did your answer include?Each hydrogen atom is bonded to the oxygen atom with a single bond.
The oxygen atom has two lone pairs.
The molecule is bent.
Oxygen is more electronegative than hydrogen.
Each O-H bond is polar.
The molecule is asymmetrical.
The asymmetry and the polar bonds produce an overall molecular dipole.
The oxygen atom has a partial negative charge, and the hydrogen atoms have a partial positive
charge.

Answers

Answer 1
Answer:

The O2 atoms have a covalent bonding and are attracted to the electrons more strongly.  

  • The sharing of the electrons gives them water molecules a slightly negative change near the O2 atom. A slight positive change near the H2.
  • Hence the option D is correct.

Which organic molecule is digested into simple sugar?

Answers

Whilst inorganic molecules, such as the mineral calcium, are broken down into smaller molecules, they aren't broken down into simpler structures, because they are already in their simplest form. 

Large organic molecules such as starch need to be broken down into simpler forms - maltose and glucose respectively via digestion. Other organic larger molecules are broken down into simpler forms like protein to amino acids and lipids to fatty acids and glycerol etc. 

Glucose is one of several simple sugars (monosaccharides). 

Biological catalysts are what help to break down these large molecules (polymers) to simpler ones (monomers), they are called enzymes.

function. A more descriptive answer can be given if the "part" is defined.

Final answer:

The job a part does within an organism, whether it is a cell, tissue, organ, or organ system, is crucial for the life and health of the organism. Each part is designed to carry out certain functions, which collectively ensure the organism’s survival, growth, and reproduction.

Explanation:

The role a part plays within an organism, also known as its function, depends on whether the part is a cell, tissue, organ, or organ system. In a multicellular organism, all parts work together to maintain the life and health of the entire organism. For example, an organ such as the heart has the function of pumping blood to distribute nutrients and oxygen around the body.

Each part is uniquely designed to suit its function. A living organism is capable of performing all physiologic functions independently, and these functions are determined by the anatomy (structure) and physiology (functionality) of its cells, tissues, organs, and organ systems.

  1. Organization: This is a key function of life where organs are systematically arranged into organ systems. They work harmoniously to perform functions of an independent organism.
  2. Metabolism: All living organisms require energy to carry out their functions. This energy is provided by various metabolic reactions happening at cellular levels.
  3. Responsiveness and Movement: Organisms respond to changes in their environment and move towards or away from stimuli for survival.
  4. Development: Organ development, or organogenesis, is the process by which tissues form specific organs during growth.
  5. Reproduction: This is a fundamental feature of all life forms to ensure the continuity of life.
