Answer:
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Explanation:
Answer:
Chromatin
Explanation:
The DNA, which is the genetic material in virtually all living cells is found in a long chain of polynucleotides. This long nature of the DNA will prevent it from fitting into the nucleus of eukaryotic cells. Hence, the cell devises a way to make this work by forming a structure called CHROMATIN.
Chromatin is formed when the long DNA molecule wraps around a set of proteins called HISTONE. Histones bind to the DNA molecule, which could are the core of the proteins to form a NUCLEOSOME structure. Each nucleosome is the basic unit of Chromatins. This nucleosome undergoes further coiling to form the CHROMATIN, which eventually forms the chromosomes the genetic material is transferred as in the nucleus.
Answer:
I think it is the secondary consumers which the energy goes back to the soil
Answer:
shark are slow evolving species because of lower gene flow and rate if reproduction.
Darwin finches undergo divergent evolution
Explanation:
Sharks have evolved slowly because of following reasons –
a) Lower rate of reproduction
b) Restricted gene flow because of isolated habitat such as stretches of deep water
c) Staying close to the eggs and hence guarding them throughout their life thereby allowing no cross mating.
d) Lower rate of mitochondrial DNA (mtDNA) evolution
Darwin’s finches show divergent evolution as different species of finches originated from a common ancestors. The beak size of finches vary form one species to other because of different diet habits
I) According to FDA there are about 38 toxic contaminants of bottled water may include, Chloride, Coliform, Arsenic, Iron, Manganese, phenols, Dissolved solids, Zinc,and Flouride. It is the work of FDA to allow certain levels of these contaminants in bottled water. Higher levels than the recommended levels may be toxic and dangerous to human beings.
ii) These contaminants are from different sources, for example chloride ions or chlorine is from the disinfectant used to treat water since the compounds are chloride compounds and also other byproducts of chlorine based disinfection. The CfCs is from the plastic making the bottle if water is exposed to sunlight.
