Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces. genetic disorder is when these thing are not working properly.
Answer: cellular respiration reverses the overall photosynthetic reaction, but less efficiently. The useful energy output of respiration is less than the energy input required for photosynthesis.
Explanation:
overall photosynthetic reaction
Light energy + 6CO2 + 6H2O —> C6H12O6 + 6O2
cellular respiration
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy (as ATP and heat)
<h2>Evolution </h2>
Explanation:
A bottleneck genetic drift and micro-evolution have occurred in the given condition
- In bottleneck effect, inferior genotype is eliminated from a homogeneous gene pool due to strong natural selection pressure and changing environmental conditions and this leads to genetic drift as a result only a few most adapted genotype survives and flourish
- Micro-evolution is a type of evolution in which formation of new species occurs at a slow pace following phyletic gradualism
- Causes of micro-evolution are point mutation and recombination
<u>Epiphyseal plate</u> allows the diaphysis of the bone to increase in length
<u>Explanation:</u>
Epiphyseal plate is the structure that allows the diaphysis of the bone to increase in it’s length. After birth the they become the center of development for the bone to grow by ossification.
Ossification is a process where the bone increases in length. In the layer of hyaline cartilage, the epiphyseal plate the osseous tissue is grown. This helps the increase in the length of the bone. Usually growth is concentrated at the end of the bones

Theres a character minimum smh but i think its d pls check though g00gle is fr33
