Answer:
The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.
It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.
Because those are traces of life meaning that there was life living there once, that life wouldn't have been able to survive there with how Antarctica is now.
What are the answers given
First of all, the most common type of CNS neuron is the multipolar neuron meaning it has many dendrites and dendritic branches, a cell body or soma, and a single axon. The information flow through this neurons starting from receiving multiple impulses from multiple synapses since this kind of neurons has many dendrites. The signal will then flow in an anterograde manner meaning the multiple signals will flow towards the cell body or the soma to be integrated. Next is that the integrated signal will flow to the neuron's axon to be transmitted to other neurons.
The answer is <span>The flagellated sperm would not be able to swim to the eggs for fertilization.
</span><span>Their life cycle of mosses has alternation of generation -
a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid
gametes which fuse to form a diploid zygote. The zygote grows into diploid
sporophyte which produces haploid spores. The spores grow into gametophyte and
the cycle begins again.
</span>Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.
