he selective breeding of wild mustard has _________ _________ and produced at least four other vegetable crops.

Answers



Choices to this question are:
A) increased biodiversity B) decreased biodiversity C) maintained biodiversity D) eliminated biodiversity

It is letter 
A) increased biodiversity 
The selective breeding of wild mustard has increased biodiversity and produced at least four other vegetable crops.
Selective breeding fights the increasing issues of food security, urbanization, population growth and even shortages of energy and water. 

In a food web, each ____________ depends on the trophic level below it for energyA) Consumer
B) Decomposer
C) Detritivore
D) Producer

Answers

Answer:

The correct answer would be A) consumers.

Consumers are the organisms which depend on other organisms for their energy needs.

In a food chain, the consumer consumes other organisms present on lower trophic level.

For example, cow, deer, et cetera (herbivore) are the primary consumers which consume autotrophs or green plants which are present on lowest trophic level.

Similarly, lion, tiger, et cetera are the highest consumers which feed on organisms present on lower trophic levels such as cow, deer, giraffe et cetera.

A) Consumer

The consumer relies on the 
trophic level below it for energy to survive.

Which of the following is a condition that must be met for a population or an allele to be in Hardy-Weinberg equilibrium?A The population in question must be small
B Organisms must be free to migrate into or out of the population
C New mutations must be introduced to the gene pool at a consistent and unfluctuating rate
D Organisms in the population must express no mating preferences

Answers

The answer is D) Organisms in the population must express no mating preferences.

Some of the conditions that must be met for a 
population or an allele to be in Hardy-Weinberg equilibrium are:

1. The population must be very large - so A) could not be the right answer.
2. There must be no migration and population must be isolated - so B) could not be the right answer.
3. There must be no mutations - so C) could not be the right answer.
4. There must be random mating, which means there are no mating preferences - so, D) is the right answer.

You have been studying a large lake ecosystem. You learn that toxins have been dumped into the water. You predict that the population with the highest concentration of the toxin would be theducks
zooplankton
algae
predatory birds
small fish

Answers

The correct answer is predatory birds.  

The flowing of toxic chemicals and heavy metals into the water body when the agricultural, industrial, and human wastes run off or are discharged intentionally into the water body is known as biomagnification. These pollutants result in genetic mutations, disease, reproductive difficulties, birth defects, death, and behavioral modifications in various marine species.  

However, the extremity of the destruction varies significantly among the species. In various circumstances, the animals close to the top of the food chain are most influenced by the procedure of biomagnification.  

Several of the harmful toxins get settle at the lower level in a water body and are then consumed by the species, which feed or live on the bottom dwellers. As these constituents are not digested, they gathered inside the bodies of the species, which consumes them.  

It signifies that the higher level predators, like fish, birds, or marine mammals accumulate more harmful concentrations of toxic substances in comparison to the animals lower on the food chain. Thus, in the given case, the more concentrated amount of toxins would be found in the predatory birds.  


Final answer:

In a large lake ecosystem, the population with the highest concentration of the toxin would likely be the zooplankton. This is because they consume contaminated algae, transferring and concentrating the toxins in their bodies.

Explanation:

The population with the highest concentration of the toxin in a large lake ecosystem would likely be the zooplankton. Zooplankton are primary consumers that feed on algae, which is where the toxin would accumulate. As they consume contaminated algae, the toxin would be transferred and concentrated in their bodies.

Although other organisms like ducks, predatory birds, and small fish may also be affected by the toxin, the highest concentration is expected in the zooplankton because they have a direct dependence on the algae.

This scenario is applicable to a Biology class in High School, where students learn about ecological interactions and trophic levels.
