When an organism joins a new population, its genes become part of the new population's pool. How does this gene flow affect populations? Question 1 options: Gene flow between populations has no effect on the gene pool. Gene flow between populations increases genetic diversity over time. Gene flow increases the chance for reproductive isolation which can cause new species to form. Gene flow between populations decreases genetic diversity over time.
Answers
Whithin a single population, as migration and successfull reproduction occur, Gene flow between populations increases genetic diversity over time. Option B.
What is gene flow?
Gene flow is an evolutive force, together with natural selection and genetic drift.
Gene flow occurs in populations that express migration. This is, individuals from one population migrate to the other and vice versa.
For gene flow to occur, migration is not enough. Successful mating events must also occur, through which individuals from one population get to mate with individuals with the other population, and produce fertile offspring.
This is how the following generations will get genes from both populations.
Gene flow has the opposite effects of genetic drift.
• It increases variability within each population
• It reduces genetic heterogeneity between populations
Different populations experiencing gene flow tend to be more similar genetically because they are interchanging genetic material.
Assuming we are making reference to a single population, the correct option is B) Gene flow between populations increases genetic diversity over time ⇒ within a population.
As new individuals enter the population and reproduce, new genes are part of the population genome, increasing its diversity.

a fossil that is older than 200 million years old can be found on land due to plate tectonics
Answers
A fossil that is older than 200 million years old can be found on land due to plate tectonics.
Plate tectonics is the movement and interaction of large sections of the Earth's lithosphere (outermost layer of the Earth) over the asthenosphere (part of the Earth's mantle). This movement can cause the formation of mountains, oceans, and the breakup of continents over millions of years. The movement of plates can also result in the uplift and exposure of rock layers that were previously buried deep beneath the surface, including those containing fossils that are millions of years old.
Therefore, it is possible to find fossils that are more than 200 million years old on land due to plate tectonics, but the process of uplift and exposure of such rocks may take millions of years and require various geological processes.

Forested floodplain wetlands benefit from periodic flooding from rivers. When floodwaters spill into the wetland, they bring water and nutrients and leave both behind. But humans have often cut off floodplains from rivers by building roads, levees, berms, etc. Think about what would happen if a river could no longer flood into these areas. How would the resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream?
Answers
The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.
If a river can no longer flood into forested floodplain wetlands due to human interventions, it would have significant consequences for the downstream areas in terms of soils, hydrology, and life.Without periodic flooding, the increased amount of water and nutrients in the river would not be able to disperse and be deposited in the floodplain wetlands. As a result, downstream soils would experience a decrease in nutrient inputs, leading to decreased fertility and altered composition. The absence of regular flooding would disrupt the natural hydrological cycle, reducing the recharge of groundwater and altering the flow patterns in the river system. This could result in decreased water availability, increased erosion, and changes in the overall ecosystem dynamics downstream.The disruption of nutrient flows and hydrological patterns would also have a significant impact on the life forms downstream. Aquatic plants, fish, and other organisms that depend on floodplain wetlands for breeding, feeding, and shelter would face habitat loss and reduced food availability. This, in turn, could disrupt the food chain and impact the abundance and diversity of aquatic and terrestrial species in the downstream areas.The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.For more such questions on flooding

A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are shown in the graph below.
Graph shows heat, measured in Joules, radiated from an aquarium over time, measured in seconds. At 0 seconds, the energy, in the form of heat, is 1.2 Joules. At 5 seconds, the energy is 1.6 Joules. At 10 seconds, the energy is 1.3 Joules. Finally at 15 seconds, the energy is 1.5 Joules.
Based on this data, he concludes that the aquarium cannot be considered a closed system for this experiment. Explain why this conclusion is invalid.
A closed system exchanges both matter and energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system can exchange energy but not matter with its surroundings, and the scientist did not measure the movement of matter.
A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
A closed system exchanges all of its matter with its surroundings, and the scientist did not measure the movement of matter.
Answers
Answer:
The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.
Explanation:
The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.
It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.

Male organisms are more susceptible to genetic disorders linked to the sex chromosome then female because they have _______, and therefore, the law of dominance doesn’t apply
Answers
Because male creatures contain X and Y chromosomes, which are sex chromosomes, the law for dominance does not apply to them and they more susceptible to sex-related genetic diseases than female species.
Why are sex-related features more prevalent in males than females?Males only inherited one X chromosome, hence they only have one chance to receive the "good" allele because females contain two versions of an x-linked allele whereas males only carry one. Males are more likely than females to exhibit X-linked characteristics.
Why are sex-related genetic diseases exclusively inherited by women?That's because X-linked diseases are typically brought on by a lack of functional copies of a gene found on the X chromosome. Males are born with just one X chromosome. Hence, they just require one malfunctioning .

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How can the presence of one species in the same ecosystem assist another?A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.
The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.
