Aquatic organisms have external fertilization and reproduction is done through mating of male and female.
<h3>How do aquatic vertebrates reproduce?</h3>
All vertebrates reproduce through mating of male and female. Aquatic species generally have external fertilization, whereas terrestrial species usually have internal fertilization.
In conclusion, aquatic organisms have external fertilization and reproduce through mating of male and female.

Answer:
Genetic drift
Explanation:
Genetic drift is defined as the random change in allelic frequencies from one generation to the other.
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
Answer: The correct answer is- all the sugar maple trees that are present in a state park.
Population can be described as a group of individuals belonging to a particular species, which inhabit a particular area.
In this question, last option that is all the sugar maple trees that are present in a state park correspond to a particular population.
Other options have organisms occupying different areas across the world.
Answer:
Damage to one side of the occipital lobe causes homonomous loss of vision with exactly the same "field cut" in both eyes. Disorders of the occipital lobe can cause visual hallucinations and illusions.
Explanation
Image result for Damage to a small part of the occipital lobe would most likely result in a:.
Injury to the occipital lobes may lead to vision impairments such as blindness or blind spots; visual distortions and visual inattention. The occipital lobes are also associated with various behaviors and functions that include: visual recognition; visual attention; and spatial analysis.
The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall serving to protect the bacteria and which is not easily washed off.
<h3>What is the bacterial capsule?</h3>
The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall and which is not easily washed off.
The bacterial capsule is a layer of polysaccharides which are found outside the cell envelope, therefore, it is regarded as being part of the outer envelope of a bacterial cell.
The bacterial capsule is associated with being the cause of various bacterial diseases.
