Answer:
the field of biology that studies the diversity of populations t the level of the gene. the frequencies of on allele (p) and the frequencies of another allele (q) in a a population all add up to 1.
Population genetics is the field of biology that studies the diversity of populations at the level of the genes, as it explains the genetic variation and their distribution among different individuals in the population.
What is the significance of population genetics?Generally, it has applications in conservation biology, medicine, and other fields of biology and helps to understand the genetic variation within and among populations and explain the evolution of organisms and how they adapt to different environments. It also explains the variation within endangered species and the genetic factors that contribute to disease susceptibility.
Hence, population genetics is the field of biology that studies the diversity of populations at the level of the genes, as it explains the genetic variation and their distribution among different individuals in the population.

Cones and flowers are the principal reproductive organs in vascular plants. However, successful reproduction is also dependent on roots, stems, and leaves as well. Evaluate each claim. Select ALL the statements that accurately describe the interplay between organ systems.
A) Fruits work with leaves to produce sugars using photosynthesis.
B) Nutrients needed for reproduction are absorbed from the soil from the root system. C) Nutrients absorbed through the roots are transported to the flowers via the xylem. D) Pollen necessary for reproduction is made in the leaves and transported via phloem.
E) Fruits contain large amounts of sugars produced in the leaves through photosynthesis.
Answer:
B) Nutrients needed for reproduction are absorbed from the soil from the root system.
C) Nutrients absorbed through the roots are transported to the flowers via the xylem.

The magnets point North when the Earth's magnetic field has (p2)
need some help :)
The magnets point North when the Earth's magnetic field has?
ANSWERI think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.
In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.
THE MAGNETIC REVERSALThe reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.

What process do scientists think explains the evolution of mitochondria and chloroplasts from bacteria
Scientists put their conclusions into this by creating th Endosymbiotic theory. The endosymbiotic theory describes how mitochondria and chloroplasts (cell organelles) came to exist in eukaryotic organisms. The endosymbiotic theory explains the evolution of mitochondria and chloroplasts. Before mitochondria and chloroplasts were organelles in a cell, they were free prokaryotic cells that were absorbed by eukaryotic cells.
The mitochondrion was originally a prokaryotic cell that could undergo aerobic respiration. After being absorbed by a eukaryotic cell, it developed a symbiotic relationship with its host cell.
The chloroplast was originally a prokaryotic cell that could undergo photosynthesis (eg. cyanobacteria). Like the mitochondria, the photosynthesizing bacteria became dependent on the host cell after being engulfed.
There is much evidence to support the endosymbiotic theory.
Both prokaryotes and chloroplasts/mitochondria have circular DNABoth have their own ribosomesBoth divide through binary fission (splitting into two)Both have their own cell membraneswhat do the letters A G C andT stand for

Visceral reflex arcs differ from somatic in that ________. visceral arcs involve two motor neurons visceral arcs contain two sensory neurons visceral arcs do not use integration centers somatic arcs contain one additional component that visceral arcs do not possess
Visceral reflex arcs differ from somatic in that : ( A ) Visceral arcs involve two motor neurons
Visceral reflex arcsVisceral reflex arc is the reflex arc in the autonomic nervous system that produces non-skeletal muscular response in certain internal organs ( heart and blood vessels ). While somatic reflex arc is a neutral pathway which occurs from the sensing to response of stimulus.
Hence we can conclude that Visceral reflex arcs differ from somatic in that : ( A ) Visceral arcs involve two motor neurons.
