Answer:
This is false.
Explanation:
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. ... Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen and iron, which were created by stars that existed before them.
1. Non random mating
In genetic equilibrium individuals must mate at random. However, in many species, individuals select mates based on heritable traits, such as size, strength, or coloration, a practice known as sexual selection.
2. Small population size
Genetic drift does not have major effects on large populations but can affect small populations. Thus evolutionary change due to genetic drift happens more easily in small populations.
<span>3. Immigration or Emigration
Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.
4. Mutations
Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.
5. Natural Selection
if different genotypes have different fitness, genetic equilibrium will be disrupted, and evolution will occur.</span>
Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple
The plants absorb light energy into chemical energy. This energy is used by the plant for fuel. The byproduct of photosynthesis is Oxygen. That is why plants are so beneficial for air quality
Answer:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life ...
