Genotype- gives your the genetic expression of an organism, while phenotype is the physical expression of an organism
Answer:
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are ultimately recycled in the ecosystem while the energy is ultimately lost from the ecosystem to the universe at large. Energy in any ecosystem ultimately comes from the Sun
Explanation:
By the way, I LOVE BIOLOGY!
the characteristics of prokaryotes are:
- Lack an organised nucleus and other membrane organelles
- Found in a central part of the cell which is known as the Nucleoid
- The cell wall of the prokaryotic cell acts as an extra layer of protection as it can help maintain dehydration and the cell shape
(Got the information from my biology notes!)

Answer:
B. 26amu
Explanation:
The nucleus of an atom in an element contains protons, electrons and neutrons. The proton number equals the electron number in a neutral atom. The proton number is also called the atomic number, denoted by Z.
The mass number also called Atomic mass unit (amu) in this case, of an element is the sum of the proton number and the neutron number in the atom of that element. The mass number is denoted by A.
Hence, A = Z + N
Where A = Mass number
Z = Proton (atomic number)
N = Neutron number
In this question, N is 11 while Z is 15
Hence, the mass number of the element in the question, in AMU, is 15 + 11 = 26amu.
