Answer: subatomic particles: negative charges (electrons) distributed in a mass of positive charge.

Explanation:

1) John Dalton's model depicted the matter as the combination of tiny, indivisible particles, called atoms.

According to this model, atoms can not be created, destroyed, or divided into smaller particles.

2) When it was discovered that all forms of matter contained negative particles, by multiple experiments with cathode ray tubes, those particles where named electrons.

3) J.J. Thompson could determine that the mass of those negative charges was much smaller that the mass of the smallest atom (hydrogen). Concluding that existed smaller particles than the atom. Hence, Dalton's model was wrong: atoms was divisible into smaller subatomic particles.

4) Then J.J Thompson proposed the plum pudding model, in which the electrons (plums) are embeded into a uniform positive mass (pudding).

Which five statements about hemoglobin and myoglobin structure are true? Each iron atom can form six coordination bonds. One of
Ulleksa [173]

Answer:

Here's what I get  

Explanation:

Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen.  

TRUE

By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom.  

TRUE

Molecular oxygen binds irreversibly to Fe²⁺ in heme.  

False. It binds reversibly with heme.

Heme is composed of an organic protoporphyrin component and a metal atom.  

TRUE

Hemoglobin and myoglobin are heterotetramers.

False. Hemoglobin is a tetramer. Myoglobin a monomeric protein.

Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.

TRUE

Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.

TRUE
