behavior is not passed from generation to generation and must be taught to offspring or developed through experience
It is true that behavior is not passed from generation to generation and must be taught to offspring or developed through experience.
What is behavior?Behavior refers to the actions or reactions of an organism in response to internal or external stimuli. It encompasses a wide range of activities, from simple reflexes and automatic responses to more complex and deliberate actions that are shaped by learning, experience, and social and cultural factors.
While genetic factors can play a role in some behaviors, such as instinctual behaviors that are critical for survival (e.g. the reflex to blink when something comes close to the eye), the vast majority of behaviors are learned through experience or taught by parents or other individuals.

Echinoderms ________. are most often found in freshwater environments have an exoskeleton of hard calcareous plates digest their food outside of the organism circulate hemolymph in their water vascular system often use tube feet to move around in their environment
Echinoderms are characterized by their exoskeleton of hard calcareous plates, water vascular system, and tube feet for movement.
Echinoderms are a group of marine animals. They possess an exoskeleton made of hard calcareous plates, which provides them with protection and support.
Their unique water vascular system is responsible for circulating hemolymph, a fluid that transports nutrients and oxygen, throughout their body. This system also powers their tube feet, which are small, flexible appendages that help echinoderms move around their environment.
Additionally, echinoderms digest their food outside of their body by releasing digestive enzymes into the surrounding water, breaking down the food before ingesting it. This adaptation allows them to consume larger prey items or scavenge on decaying matter more efficiently.

Evolution has yielded some novel predictions is True.
Evolutionary theory has led to a number of novel predictions, many of which have been supported by subsequent empirical evidence. For example, evolutionary theory predicts that species should be adapted to their environments, and this has been supported by a wealth of data on the morphology, physiology, and behavior of organisms. Evolutionary theory also predicts that species should share common ancestry, and this has been supported by the fossil record and molecular phylogenetics.
Additionally, evolutionary theory predicts that species should exhibit certain patterns of variation and distribution, and this has been supported by studies of biogeography and population genetics. Overall, the success of evolutionary theory in making these predictions provides strong evidence for its validity and utility as a scientific framework.

Evolution is a well-founded theory that produces many novel predictions. It can lead to the emergence of multicellularity in single-celled organisms and can predict certain aspects of human behavior. The process involves organisms adapting to their environment, and sometimes results in successful adaptations due to random genetic changes.
Explanation:True, evolution has indeed yielded some novel predictions. Consider the claims about the evolution process which highlights its ongoing nature. The combined use of strong and weak selection demonstrated that evolution, under artificially imposed conditions, can lead to the emergence of multicellularity in single-celled organisms. In addition, evolution can make a host of predictions about human behavior, such as memory, mate choice, kin relations, parenting and social organization.
Evolution didn't come without its share of misconceptions. One such view was that evolution is entirely random. However, evolution actually results in organisms adapting better to their environment. On the other hand, another misconception is that evolution produces perfectly fit organisms. The reality is that evolution causes random changes in the genetic code, which can sometimes, not always, lead to successful adaptations.
Furthermore, scientific evidence supports the belief that evolution is an ongoing process in all organisms, including prokaryotes. Thus, evolution is a well-founded theory backed by robust fossil evidence and shared DNA sequences, even though it's a process that cannot be directly observed today.

Explanation:
If there is NO SELECTIVE SURVIVAL based on shell thickness within a population of snails, what happens to shell thickness in response to crab predation? The average shell thickness increases within each generation, but there is no change in shell thickness from generation to generation. There is evolution by natural selection of shell thickness, and average sheil thickness increases every generation. There may be evolution of shell thickness, but not through natural selection and not necessanly toward thicker shells. There is no change in shell thickness within the population.
If there is no selective survival based on shell thickness within a population of snails, there will be no change in shell thickness within the population.
In a population of snails, if there is no selective survival based on shell thickness, it means that the thickness of the shells does not provide any advantage or disadvantage in terms of survival and reproduction. In this scenario, there would be no driving force for natural selection to favor individuals with specific shell thicknesses.
Without selective pressure from crab predation, there would be no differential survival or reproductive success associated with shell thickness. As a result, the frequencies of different shell thicknesses would remain relatively stable from generation to generation.
While there may still be variation in shell thickness within the population due to genetic and environmental factors, there would be no consistent directional change in the average shell thickness over time. Any changes in shell thickness would be random or due to factors other than natural selection.
Therefore, if there is no selective survival based on shell thickness, the population of snails would exhibit no change in shell thickness over generations.

Can someone help me briefly describe the main similarities and differences between prevalence and incidence in the paragraph below. In lay terms, I am having trouble with prevalence and incidence terms.
The shrimp cocktail and Romaine lettuce salad are most likely to be the infective items because more people who ate them later became sick with gastrointestinal symptoms.
The total number of persons who ate the shrimp cocktail and Romaine lettuce salad and later became sick with gastrointestinal symptoms is 48+46=94.
The total number of persons who ate the shrimp cocktail and later became sick with gastrointestinal symptoms is 48+10=58.
The total number of persons who ate the Romaine lettuce salad and later became sick with gastrointestinal symptoms is 46+61=107.
The total number of persons who ate the shrimp cocktail is 57+140=197.
The total number of persons who ate the Romaine lettuce salad is 57+77=134.
The total number of persons who did not eat the shrimp cocktail is 77+35=112.
The total number of persons who did not eat the Romaine lettuce salad is 140+35=175.
The percentage of persons who ate the shrimp cocktail and later became sick with gastrointestinal symptoms is 94/197=47.7%.
The percentage of persons who ate the Romaine lettuce salad and later became sick with gastrointestinal symptoms is 107/134=79.9%.
The percentage of persons who did not eat the shrimp cocktail and later became sick with gastrointestinal symptoms is 10/112=8.9%.
The percentage of persons who did not eat the Romaine lettuce salad and later became sick with gastrointestinal symptoms is 61/175=34.9%.
Explanation:
Based on the percentages, the shrimp cocktail and Romaine lettuce salad are most likely to be the infective items.
The total number of persons who ate the shrimp cocktail and Romaine lettuce salad and later became sick with gastrointestinal symptoms is 94. This is the highest number of persons who became sick after eating a specific food item or combination of food items. The percentage of persons who became sick after eating the shrimp cocktail and Romaine lettuce salad is also the highest, at 47.7%. This indicates that the shrimp cocktail and Romaine lettuce salad are most likely to be the infective items.
Prevalence and incidence are both measures used in epidemiology to understand the occurrence and distribution of diseases within a population.
While they are related, there are key differences between the two:
Prevalence: Prevalence refers to the total number or proportion of individuals who have a specific condition (in this case, gastrointestinal symptoms) within a population at a given point in time. In the provided paragraph, the prevalence is calculated as the total number of persons who became sick after eating the shrimp cocktail and Romaine lettuce salad, which is 94.
Incidence: Incidence, on the other hand, refers to the number or rate of new cases of a specific condition (in this case, gastrointestinal symptoms) within a population over a specified time period. In the given paragraph, the incidence is not explicitly calculated, as it requires tracking new cases over time. However, it can be inferred that the number of new cases would be lower than the prevalence since it only considers individuals who recently became sick.
In summary, prevalence measures the total number or proportion of individuals with a condition at a specific time, while incidence measures the number or rate of new cases over a defined time period. Both measures provide valuable information about the occurrence and impact of a disease within a population.

Suppose Jennifer is a horticulturist that specializes in the cultivation of orchids. She houses the orchids in a temperature-controlled and humidity-controlled greenhouse. A salesman approaches Jennifer and attempts to sell her a special fertilizer that promises to increase flower production Jennifer, who dabbles in genetics, insists that the fertilizer will have no effect on flower production. She has calculated the narrow-sense heritability of flower production in her orchids and found it to be 0.98. Jennifer claims that a narrow-sense heritability of 0.98 indicates that 98% of the variance in flower production is determined by genetic differences, so a fertilizer would have little effect on flower production in the orchids The salesman disagrees with Jennifer and continues to assert that the fertilizerll increase flower production. Who is correct and why? O Jennifer is correct. Environmental conditions did not previously impact flower production so it is unlikely that a fertilizer will alter the effects of the genetic factors O Jennifer is correct. High heritability of a trait indicates that only genetic differences within a population will account for a trait.O The salesman is correct. Environmental factors will still affect an orchid with a high heritability of flower production O The salesman is correct. High heritability of a trait within a population does not exclude new environmental factors from affecting the trait.
Jennifer is correct. A narrow-sense heritability of 0.98 indicates that 98% of the variance in flower production is due to genetic differences within the population. This means that environmental factors, such as the application of a fertilizer, will have little effect on flower production in her orchids.
This is because the majority of the variance in flower production is already determined by genetic factors, and any changes in environmental conditions would have little impact on this genetic component.
Additionally, Jennifer's use of a temperature-controlled and humidity-controlled greenhouse already ensures that the environmental conditions are optimal for orchid growth and flower production. Therefore, the introduction of a fertilizer would not significantly alter the existing environmental conditions and would not lead to a noticeable increase in flower production.
In summary, Jennifer's understanding of the high heritability of flower production in her orchids and its implications for the potential impact of a fertilizer on flower production is correct. The salesman's assertion that the fertilizer would increase flower production is unlikely to be true given the high heritability of the trait.

What if the light intensity was 1000, but the only available wavelengths was 400. What do you predict would happen to the ATP production, and why?
ATP production depends only on intensity of light and not on wavelength of light.
The production of plant food, the size and color of leaves, and flowering are all impacted by light intensity. Plants that are grown in low light typically have spindly growth and leaves that are light green. Similar plants cultivated under intense lighting typically have shorter, better branches and larger, dark green leaves.
Lack of light causes the plants' leaves to yellow, their stems to weaken, and their leaves to shrink. Lack of light causes plants to eventually lose their color and perish. The growth of plants can potentially be harmed by excessive light exposure. One of the many elements influencing plant growth is light.

Answer:
relies on the evaluation of dreams and the unconscious desires.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
This ultimately implies that, the manner in which living organism such as humans look and behave is largely dependent on both the traits inherited from their parents and the environment in which they grew up or stayed.
Hence, the behavioral genetics approach relies on the evaluation of dreams, unconscious desires, twin, family, and adoption studies which are used to investigate the gene possessed by living organisms or their environment interactions.
