Answer:
d. All of the above exemplify the difference between a population and an individual.
Explanation:
A population is a group of individuals of the same species that live in a particular geographical area and are able to interbreed. A population is described with respect to several features such as death and birth rates, age structure, density, dispersion, change in the population size due to density-dependent and density-independent factors and the survivorship curve.
These features are not exhibited by a particular individual. Natural selection also works at populations. The evolutionary forces act upon populations to change their allele and genotype frequencies. Therefore, populations are the unit of evolution and change genetically over time, not the individuals. Population ecology studies the size of a populations and the trends and causes of changes in the populations over time.
Answer:
1) genetics
2) gregor mendel
3) easy to grow, can be shown year, used for similar studies
4) we are the parents produce offspring that would carry the same phenotype
5) he removed the anthers from the flowers
6) a trait or character is a feature of an organism.
7) the basic physical and functional unit of heredity
8) one of the possible forms of a gene
9) the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction.
10) “P” for parental generation.
11) F1 generation refers to the first filial generation
12) F2 second filial generation consists of the offspring from allowing the F1 individuals
13) The dominant allele is the one that gets expressed.The recessive allele is still there, it just isnt shown.

Answer:
Rocks or lava
Explanation:
In 1° succession there is no soil.. And the process of soil formation take very long time.
In 1° succession rocks or lava is present and lichens, soil erosion, wheathring of rocks helps in soil formation.
