A city was intensively sprayed with DDT to control houseflies. The number of houseflies was immediately greatly reduced. Each year thereafter, the city was sprayed again, but the flies gradually increased in numbers until 10 years later, when they were almost as abundant as they were when the control program began. Which explanation applies to this situation?The DDT killed most flies. The few that were already naturally resistant survived and passed this resistance on to their offspring.Flies from other areas moved in and replaced the ones killed by DDT.The DDT caused new mutations to occur in the surviving flies, resulting in resistance to DDT.The few flies that were affected by DDT but survived developed antibodies to DDT, which they passed on to their descendants.

Answers

Answer:

The DDT killed most flies. The few that were already naturally resistant survived and passed this resistance on to their offspring

Explanation:

Natural selection is evolutionary mechanism which favours traits of an organism that help him survive and reproduce. In the example, above,  naturally resistant DDT flies that survived after the use of pesticide had the favuoruable trait (resistance) by natural selection.

Coral habitat is diminishing world-wide at an alarming rate. From what you know about sponges, cnidarians and Ctenophores, why is the conceding from an ecological perspective?

Answers

Destruction of coral reefs would cause an imbalance in the ecosystem. Some species could be driven to extinction.  

Coral reefs are the base of the most diverse marine ecosystem in the world. They are often referred to as the ‘rainforest’ of the oceans and seas.  They provide shelter for cnidarians, sponges, crustaceans, and etcetera and provide hiding grounds from predators.

Which statement best supports the theory of evolution as a reliable explanation for the diversity of life? Scientists observed that many species have homologous structures. The original proposers of evolution had a huge amount of evidence. Scientists found that some traits are inheritable. It is the theory taught at the best research institutions.

Answers

Theory of evolution is based on natural selection. Presence of homologous structure supports this theory. Thus, first option is correct.

What are homologous structures?

Homologous structures can be defined as the structures that share the same basic shape but differ in functions.

Homologous structure are common in ancestry but they are thought to be modified or adapted for specific function.

Homologous structures are the part of divergent evolution since the same structure is modified for performing different function than its ancestor.

Forelimbs of humans and forelimbs of bat can be considered as homologous structures as they have same skeletal structure but both of these function differently.

Homologous structures are considered as an evidence to support the theory of evolution as homologous structures are selected on the basis of natural selection.

Thus, homologous structures are important in determining the course of evolution.

Bacteria in the soil converts this nutrient into a usable form. Plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant. An animal eats the plants, and the nutrient becomes part of the animal. When the animal dies, it decomposes, returning the nutrient back to the soil. Which cycle is being described? A. water cycle
B. carbon cycle
C. nitrogen cycle
D. phosphorous cycle

Answers

C. nitrogen cycle. Plants have to convert nitrogen into usable form to be used by living things. Cycling of nitrogen is happens through four processes: nitrogen fixation, decay, nitrification and denitrification.

1. Information in the environment that causes an animal to react is termed as:a stimulus.

2. The more complex an animal’s response to a stimulus, the more likely it is that the animal has (1 point)
many sensory neurons.

3. Of the following choices, the simplest form of nervous system is a 
nerve net.
