Bond [772]2 years ago
7 0

Answer:

Both:

-They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues.

Cartilage:

-Cartilage is thin, avascular, flexible and resistant to compressive forces.

-Cartilages are soft and flexible components present in ear, nose and joints.

Bone marrow:

-Bone is highly vascularised, and its calcified matrix makes it very strong.

-Bones are hard and tough which gives the structural framework of the skeleton in the body.

Why is carbon ideal for making different compounds?
In-s [12.5K]

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

Tails of phospholipids that don't like water
densk [106]
Those tails are called hydrophobic. You can note the etymology: hydro= water, phobi = fear, aversion, dislike.

Phospholipds' tail is a long non polar chain, made of Carbon and Hydorgens, that rejects water (a polar solvent) and is attracted to non-polar compounds (oil for example).  That is why that tails can atract dirt.

Two different compounds are formed by the elements nitrogen and oxygen. The first compound, compound P1, contains 64.17% by mass
xz_007 [3.2K]

Answer:

Explanation:

To solve the problem, we must know the kind of compounds we are dealing with.

For the first compound, P1 and second compound P2:

                                N                       O                         N                     O

Mass percent       64.17                 35.73                  47.23               52.79

Atomic mass          14                      16                         14                    16

Number of

moles            64.17/14            35.73/16            47.23/14    52.79/16      

                            4.58                  2.23                     3.37                  3.30

Simplest

ratio                 4.58/2.23            2.23/2.23             3.37/3.30         3.3/3.3

                              2                           1                             1                        1

                             

P1 compound is N₂O

P2 compound is NO

These are the compounds,

   In N₂O = 28:16

          NO = 14:16

This is the ratio of nitrogen to a fixed mass of oxygen for the two compounds.

1. What first prompted James Watson's desire to solve the structure of DNA?
GuDViN [60]

<u>Explanation:</u>

1. It was as a result of a blurry picture of the DNA eye made by scientist, Maurice Wilkins, this glimpse of the DNA made James Watson even more curious about the DNA.

2. They were considered an unlikely pair due to their age difference of about 12 years. Seemed unlikely because there was a 12 year age difference. However, they are considered a perfect team to solve the structure since James Watson has a strong background in biology, while Francis Crick is an expert in x-ray crystallography.

3. Other researchers also racing to find the structure include;

  • Rosalind Franklin, and
  • Linus Pauling.

4. It is important to note that the data provided by Rosalind Franklin enabled Watson and Crick to better understand the chains that make up the DNA.

5. In the year, 1962 they were awarded the Nobel prize in Physiology and Medicine. They were only three recipients because at the time they were the only living early contributors to the study of the DNA.
