Leaf need water and minerals and root helps to take it from soil and passes it through stem.
stem also holds leaf in place.
hope this helps
They are genetically and reproductively isolated. For the mule the specific isolation mechanism is termed as "Hybrid Inviability", where the postzygotic isolating mechanism prevents the hybrid from passing on their genes. A zygote may form with the sperm and egg, but the embryo will dies after a few cell divisions. The genetic information from male and female parents is insufficient to carry the organism through morphogenesis. *There are rare documented cases of a mule producing a viable offspring.
Answer:
Please see below
Explanation:
The reason behind this is the phenomenon of natural selection. The deleterious mutations do not provide a survival advantage so they are selected against, which results in these type of mutations to not be passed on - rather, they eventually get eliminated from the population.
I would say Spruce because they don't reproduce A-sexually like the other 3 options.
Answer:
Genetic drift decreases the genetic diversity within a specie's population. Genetic drift is a change in the allele frequencies due entirely to random chance and probability and is more likely to affect smaller populations and groups than larger ones. Genetic drift can also play a role in the development of a new species.
