Embryos go through various stages that suggest the animal’s evolutionary process.
its right
Embryos help scientists that Embryos go through various stages that suggest the animal’s evolutionary process.
What is structural evidence for evolution?Observing anatomical features shared between organisms (including ones that are visible only during development) can indicate that they share a common ancestor.Structural evidence can be compared between extant (currently living) organisms and the fossils of extinct organisms.EmbryologyEmbryology is important to understanding a species' evolution since some homologous structures can be seen only in embryo development. For example, all vertebrate embryos, from humans to chickens to fish, have a tail during early development, even if that tail does not appear in the fully developed organism.Thus, we can conclude that embryos go through various stages that suggest the animal’s evolutionary process.

The can occur if a small group of organisms migrates to a new location and becomes isolated from the rest of the population.
Answer:
Over time, a series of random occurrences can cause an allele to become more or less common in a population. This is called Genetic drift.
When a population is severely reduced by an environmental disaster such as a fire, the result is a Bottleneck effect due to the reduced genetic diversity of the survivors.
The Founder effect can occur if a small group of organisms migrates to a new location and becomes isolated from the rest of the population.
Explanation:
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.
Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.
Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.
The bottleneck effect -a case of genetic drift-, mostly affects smaller populations after the occurrence of a natural disaster or some human action -such as extensive hunting, for instance-. These events might act as a pressure that reduces significantly the number of individuals in a population. In these situations, some alleles are lost, and the survivors have a different genetic charge than the one of the original population. There might be a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.Select a hypothesis above that would help restore equilibrium and explain your reasoning.

D. New species form due to isolation
Answer:
A. Charles Darwin.
B. Homologous structure
C. Adaptation.
D. Speciation.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
A. Charles Darwin: he developed the theory of natural selection based on certain evidences. Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
B. Homologous structure: it involves similar anatomical structures that are having common ancestry or from the same lineage.
C. Adaptation: it is an inherited trait that allows individuals to survive better.
D. Speciation: it is an ecological and biological process through which new species are formed due to isolation.

Explanation:
:) answer mom
The charge of object y will be positive since it will have excess proton and less electron.
What is positive charge?A positive charge is obtained when an atom losses its electron usually a metal. It simply defines the excess of proton in an atom or deficient of electron in an atom.
If object x acquires a negative charge, then object y must have supplied the excess electron to it.
Thus, the charge of object y will be positive since it will have excess proton and less electron.

B. The Crocodile gets its teeth cleaned and the Plover gets food
C. The Crocodile gets protection and the Plover gets food
D. Crocodile gets food and the Plover gets cleaned
Answer:
B.
Explanation:
Egyptian plovers and crocodiles have a unique symbiotic relationship. Crocodiles can’t use dental floss, they get food stuck in their teeth. All that food rots their teeth and probably causes some pain. When a crocodile feels the need for a good tooth cleaning it will sit with its mouth wide open. The Egyptian plover bird sees the invitation, and if one is nearby it will fly into the mouth of the crocodile, eat the food stuck in its teeth, and fly away unharmed.
