Answer:
A. the rise and fall of the tides. 
C. a dropped object always falls toward Earth. 
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth. 
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object. 
 
        
             
        
        
        
The question is incorrect. The correct question is as follows:
The prosthetic group of hemoglobin and myoglobin is _______?
The organic ring component of heme is _______?
Under normal conditions, the central atom of heme is ________?
In ________ the central iron atom is displaced 0.4 A out of the plane of the porphyrin ring system.
The central iron atom has _______ bonds: ________ to nitrogen atoms in the porphyrin, one to a _______ residue and one to oxygen.
Answer:
The hemoglobin is an important protein that transport oxygen in the body and contains the pigment that gives the red color to the red blood cells. The myoglobin protein is responsible for transport of oxygen in muscles.
The heme molecule acts as prosthetic group for both myoglobin and hemoglobin. The porphyrin ring is present in heme molecule. The iron molecule especially Fe2+ is present in heme molecule. The deoxyhemoglbin states occur when the central atom is displaced 0.4 Å. The iron central atom can form six bonds and forms four bonds with the prophyrin of nitrogen and one bond with histidine molecule. Histidine acts as a buffer fir the blood. 
 
        
             
        
        
        
Answer:
b
Explanation:
First, let us look at the result of crossing the two genotypes Mmpp and mmpp.
Mmpp will give the gametes Mp, Mp, mp, and mp
mmpp will give the gametes mp, mp, mp, and mp
The two sets of gametes can thus be lined up on both axis of the Punnet's square as shown in the attached image.
Genotypes of the offspring: 8 Mmpp and 8 mmpp
<u>Since the two genes follow simple Mendelian inheritance pattern, the 2 genotypes automatically equates to 2 phenotypes in the ratio 1:1.</u>
<em>Hence, the correct option is </em><em>b</em><em>.</em>
