Which of the following has had the greatest economic consequences for agriculture in recent years? (4 points)
Irrigating land
Intense storms
Melting ice caps
Overfishing oceans
One of the greatest economic consequences of agriculture in recent years is overfishing.
Economic consequences of agricultureAgricultural activities have led to overfishing.
Overfishing leads to a reduction in fish biodiversity and the loss of important species that could serve as food, drugs, or industrial materials for the use of man or his livestock.
Overfishing means that there will not be enough fish for humans in the nearest future. This may result in a malnourished human population.
Overfishing can also cause ecological problems such as disruption to food chains.

Which of the following best describes why in general there are more hares in the ecosystem than foxes.
In 1945 there was a major event that caused the number of hares to dramatically increase. That is why there continues to be more hares than foxes here.
Hares are a lot smaller than the foxes, so more of them can fit into different niches. They can hide better in all of the bushes and behind rocks.
This is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to support the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development
Answer:
C
Explanation:
The reason why there are more hares than foxes in the ecosystem is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to supports the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development.

Which of these causes evolution?
A. Random mating
B. Natural selection
C. No mating at all
D. Extremely large population sizes
Natural selection causes evolution. The correct option is B.
What is natural selection?Natural selection refers to the process that leads to the adaptation of organisms to their environment.
Natural selection forces either select for or against traits. Traits that aid organisms in adapting are selected for, while those that do not aid in adaptation are selected against.
Traits that are selected for are allowed to perpetuate in the population while those that are selected against gradually fade from the population.

mark me a brainliest tysmexplain why the metric system and si are important
Answer:
In simple terms, the metric system (which is the same as SI) is important because it's more coherent than the imperial system.
Explanation:
The metric system is far more used worldwide compared to the imperial system, where the imperial system is only officially used in three countries (U.S, Liberia, Myanmar).
There are multiple reasons why the metric system is important, but the most critical reason is that it's very easy to understand pertaining to calculations. The measurement system of SI is designed to make measurements/calculations easy to perform and understand. This is why scientists prefer using the metric system over imperial.
You can make some small comparisons:
--> Metric is consistently based on decimal numbers, while imperial uses different number systems (base 3, 8, 12, 14, 16, etc.,)
--> Metric works well with percentages, while imperial does not
--> Metric units are the same internationally, while some imperial units differ (i.e different pints, gallons, tons, etc.,)
There are fewer, simpler measurements in the metric system as compared to imperial where calculations start to get overcomplicated due to the amount of measurements/units in the system.
In layman's terms... metric is a boat on smooth water with perfect weather, while imperial is a boat on rough waters during a storm.
Question 11 of 30
Under ideal conditions, how do allele frequencies change over time?
A. The frequency of the recessive allele increases in each generation.
B. The allele frequency does not change from one generation to the
next.
C. The frequency of the dominant allele increases in each generation.
O D. The alleles eventually reach a 50/50 balance.
The frequency of the dominant allele increases in each generation. Thus, the correct option is C.
What is natural selection?Natural selection is a process in which more environment-adapted organisms tend to survive and reproduce more frequently than less environment-adapted ones.
Because rare alleles are typically found in heterozygotes, the initial increase in frequency of a rare, advantageous, dominant allele is faster than that of a rare, advantageous, recessive allele. Therefore, natural selection won't be able to "see" a new recessive mutation until it is prevalent enough to manifest in homozygotes.
Once a population is in Hardy-Weinberg equilibrium, its frequency distribution won't vary from generation to generation.
