A block of wood has a mass of 120 g
and a volume of 200 cm3. What is the density of
the wood?

Answer:

Proteins are composed of amino Acids

Answer:

Nucleic acids are made from smaller building blocks known as nucleotides.

The main function of nucleotides: is to form polynucleotides, which are strands of genetic information that can wrap around each other to form a DNA double helix.

Explanation:

Answer:

The breakdown of glucose (C6H12O6) has a free-energy change of -686 kcal per mole of glucose decomposed. - Catabolism is linked to work by a chemical drive shaft: ATP. To keep working, a cell must regenerate its supply of ATP from ADP and inorganic phosphate.

Answer: Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is a cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.

Answer:

cellulose

Explanation:

lipids are fats oils or waxes. cellulose is a fiber

Answer:

cellulose    

Explanation:

Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.

Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.

Proteins

Explanation:

After water, Proteins are the next most abundant substances in the human body.

In adult men , 60% of body is comprised of water whereas in women , 55% of body is comprised of water.

Protein makes up around 20% in body and is present in every cell.

Proteins are large complex molecules and play critical roles in the body. They do most of the work in their cells and required for structure functions and regulation of body tissues.

Proteins are made up of smaller units called amino acids, which are attached to one another in long chains.

There are 20 different types of amino acids that can be combined to make a protein.

The sequence of amino acids determines about each protein’s unique 3-dimensional structure and its specific function.

Amino acids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes.

Functions of Proteins:

1. As an Antibody-  Bind to specific foreign particles such as bacteria and virus to help protect the body.

2. As an Enzyme- Carry out thousands of chemical reactions taking place inside the cell

3. As a Messenger- Transmit signals to coordinate biological processes between different cells, tissues and organs.

4. As a Structural Component- Providing structure and support to cells.

5. Transport/Storage- Binding and carrying atoms and small molecules within cells and throughout the body.

Answer:

your answer is B.  The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.

Explanation:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
