<span>In a ecosystem,rocks are an example of an abiotic factor because they are not a living part of the environment.  From context of the statement, an abiotic factor is the non-living part of the environment in a ecosystem.</span>
        
                    
             
        
        
        
 
<span>The answer is Haploid spores germinate to give rise to protonema, which later develops into a sporophyte.</span>
A protonema (plural: protonemata) is a
thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte life
cycle..
<span>A haploid gametophyte ( each of whose cells contains a fixed number of
unpaired </span>chromosomes)  gives rise to a <span>diploid sporophyte</span>,.
Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes
that grow into sporophytes. 
 
        
             
        
        
        
Answer:
d. BB
Explanation: The only possible phenotype would be BB because if you draw a Punnett square you see that you get BB, BB, BB, and BB so that is the only posssible genotype.
 
        
             
        
        
        
<h2>Answer and Explanation </h2>
The cell respiration is a process in which the sugar molecules in the human body are broken into a form of energy which can be utilized by the cell. The cell respiration is needed to build up the adenosine triphosphate (ATP) and then it releases waste products from the cell. For this biochemical process, the cell uses oxygen hence, this process is also called aerobic respiration.
 
        
        
        
Several months after split-brain surgery, the number of incidents of conflicts between the two hemispheres diminishes. Conflicts between the two hemispheres eventually diminish because the left hemisphere suppresses the right hemisphere's interference.
