The common ancestors of birds and mammals were very early (stem) reptiles, which almost certainly possessed 3-chambered hearts. Birds and mammals, however, are alike in having 4-chambered hearts. The 4 chambered hearts of birds and mammals are best described as homoplasies.
<h3>
What about homoplasies?</h3>
- It is more frequently a modified version of an inherited characteristic.
- For instance, the scales that were already present in its reptilian parent led to the evolution of feathers in birds.
- Similar to reptiles, mammals developed fur from their predecessors' scales.
- The same set of data can typically yield more than one potential cladogram.
- Different species of legged lizards developed into snakes and lizards with limbless bodies.
- Natural selection does not affect a sizable number of mutations.
- They came to the conclusion that reptiles, birds, and mammals all descended from the same ancient reptilian progenitor.

Not sure if this is the format you want it in but
F1:
Genotype: RWHh, RWHh, RWHh, RWHh
Phenotype: basically all of them would have the roan coat and they would be hornless
F2:
Genotype: WWHH, RWHh, RRHh, RWhh
Phenotype: one will have a white coat and hornless, roan coat and hornless, red coat and hornless, roan coat and horned
Hope this somewhat helped
Answer:
so here correct option is A. 5
Explanation:
solution
as number of population groups live in a definite area is called diversity
so here in 1 there is only 2 groups of population
and in 2 there is 3 types of population groups
and in 3 there is 2 type of population groups
and in 4 there is 4 type population group
but they are not not evenly abundant and population of 1 group that is much less
so it might be a foreign population group
so here in 5 there is 4 type of population group which means it has higher diversity compare to other
so here correct option is A. 5
Commensalism is the term you are looking for
Answer:
Homeostasis involves maintaining a balance of several factors that make a cell healthy.
Explanation:
The cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
