Bellwork: of the locations of earthquakes over the past 10 years were plotted on a world map, which of the following would be observed?
A. Earthquakes occur with the same frequency everywhere on Earth.
B. Earthquakes generally occur along the edges of tectonic plates.
C. Earthquakes most frequently occur near the middle of continents.
D. Earthquakes do not seem to occur in any consistent pattern.​

Answers

Answer: B.

Explanation:

It's not A, because earthquakes happen at different magnitudes depending on how the plates shift beneath them.

It's not C, because tectonic plates are scattered among the earth.

It's not D, since the pattern of earthquakes are dependent on the shifts of tectonic plates.

It's B because tectonic plates are the reason earthquakes happen. Everytime they shift or move, an earthquake occurs. There may be some earthquakes that are not near tectonic plates but the majority are, which is why the question uses the word "generally occur."

Two unlinked loci affect mouse fur color. nn or nn mice are agouti. mice with genotype nn are albino because all pigment production is blocked, regardless of the phenotype at the second locus. at the second locus, the a allele (agouti coat) is dominant to the a allele (black coat). what would be the result of a cross between two agouti mice of genotype nnaa?

Answers

The result of a cross between two agouti mice of genotype nnaa are albino offspring because mice with genotype nn are albino (pigment production is blocked by epistasis).

What is epistasis?

Epistasis is a genetic phenomenon where the presence of a gene variant alters a phenotype influenced by other genes.

A gene is epistatic when a variant (allele) can alter the expression of another gene in the same signaling pathway.

Epistatic interactions are very common in nature and many traits are influenced by this type of interaction.

Approximately how many kilograms (kg) of carnivore (secondary consumer) biomass can be supported by a field plot containing 1000 kg of plant material?

Answers

About 10 kilograms (kg) of carnivore biomass can be supported by a field plot containing 1000 kg of plant material.

What is an ecosystem?

An ecosystem is a self-supporting system consisting of living and non-living components.

In an ecosystem, a carnivore is a secondary consumer.

In energy flow in an ecosystem, 10% of biomass is transferred from primary producer to primary consumer, 10% from primary consumer to secondary consumers.

Thus, 1% of energy is transferred to the carnivore.

1% of 1000 kg = 10 Kg.

Therefore, 10 kilograms (kg) of carnivore biomass can be supported by a field plot containing 1000 kg of plant material.
