When you hear talk of evidence for evolution, the first thing that frequently comes to mind for most people is fossils. The fossil record has one important, unique characteristic: it is our only actual glimpse into the past where common descent is proposed to have taken place. As such it provides invaluable evidence for common descent. The fossil record is not "complete" ( fossilization is a rare event, so this is to be expected), but there is still a wealth of fossil information.
Answer:
The mutation will be fixed by genetic drift.
Explanation:
Genetic drift is the change in the allele frequencies in a population that occur randomly. It is an evolutionary process (like natural selection), that is associated with the reduction in genetic diversity by the fixation of rare allelic variants and neutral mutations. In this example, this point mutation is neutral since, according to data, the population is evolving by genetic drift. Moreover, it is also important to note that a mutation that involves one nucleotide is also called Single Nucleotide Polymorphism (SNP).
Answer:
Los virus son más pequeños y no son células. A diferencia de las bacterias, necesitan un huésped como un humano o un animal para multiplicarse.
Las bacterias son organismos vivos unicelulares. Tienen una pared celular y todos los componentes necesarios para sobrevivir y reproducirse.
Los virus no se consideran "vivos" porque requieren una célula huésped para sobrevivir a largo plazo, para obtener energía y para reproducirse.
Explanation:
Answer:
it Changes according to the receptor.
Explanation:
Every cell has different receptors in the membrane, these receptors are specific, but different receptors can read one signal molecule, according to the receptor, this molecule can activate or inactivate different path ways.
Let me put it this way, if I give the same message to a botanist and a gardener they both are going to read it in different way even knowing it is the same.
Deforestation is one major concern with harvesting wood. There are also all types of organisms that lose their habitats.
