Larvae of the Diamondback moth feed on cauliflower paleo Aunt Farmers commonly used pesticides to repel them all from the cauliflower plants the larvae of the Diamondback moth arnab resistant various types of pesticides which statement best describes how the larvae became resistant?
Answer:
Mutation.
Explanation:
Mutation is the factor that is responsible for the acquiring resistance of various pests against pesticides because in mutation the genetic makeup of the organism changes which has no effect of the chemicals applied on them. Repeated use of the same type of pesticides to control a specific pest can cause changes in the genetic makeup of a pest that leads to another form of pest which causes pesticide resistance in the new type of pest so we can say that mutation is the main cause of resistance in pests.

What is the difference between natural selection and selective breeding? Then, give examples of natural selection and selective breeding?
Natural Selection is when traits are "naturally" selected for, because "survival of the fitttest." Example would be a species becoming bigger over time, because the smaller animals of that species were more likely to be eaten by predators. Natural selection is when the "best" trats are passed down due to chance
Selective breeding is if an outside forece (like a dog breeder) "chooses" a triat to be passed down. Example, instead of breeding a brown dog with a white dog, the breeder breeds two black dogs together in orer for the litter to all have black fur

Which of the following occurs during
Prophase?
Answer: Nuclear envelope breaks down!
Answer:
During prophase, chromosomes condense and exit the nuclear envelope to align during metaphase. Anaphase follows metaphase, and is characterized by the separation of sister chromatids. Telophase is the final mitotic stage, during which the cell prepares for cytokinesis.

C.) Photosynthesis.Explanation:
I checked the chemical equation as well as the diagram, and it looks accurate.
The chemical equation for photosynthesis is:
6CO2+6H2O → C6H12O6+6O2.
So your answer is correct.
In plants, photosynthesis is used to convert light energy from sunlight into chemical energy (glucose).
Carbon dioxide, water, and light are used to make glucose and oxygen.

Provide one reason that preventing fusion of multiple sperm with one egg in sea urchins has provided a survival advantage over evolutionary time
Answer:
To produce a healthy offspring.
Explanation:
To make a healthy offspring is the reason that is responsible for preventing fusion of multiple sperm with one egg in sea urchins because if more sperm are fused with one egg, faulty segregation of chromosomes occurs during cell division that leads to the production of nondiploid cells due to which no further development occurs. So by avoiding such type of faults in the cell, only one sperm will fuse with egg not multiple sperms.
That is one reason that preventing the fusion of multiple sperm with one egg in sea urchins has provided a survival advantage over evolutionary time to produce healthful offspring.
To make a healthful offspring is a purpose this is liable for stopping the fusion of more than one sperm with one egg in sea urchins due to the fact if greater sperm are fused with one egg, defective segregation of chromosomes happens for the duration of the molecular department that results in the manufacturing of nondiploid cells because of which no similar improvement happens. So through averting such sort of faults withinside the molecular, best one sperm will fuse with egg now no longer more than one sperms.
What are offspring?The making of the reproduction is a brand new organism produced through one or greater parents.

A. A resource that is so scarce (in restricted quantity) that it limits the size of a
population is called a limiting factor. Any single resource can be a limiting factor
to a population size. For example, the amount of water available can affect the
number of plants that can grow in an area.

In what ways do humans affect the different trophic levels in ecosystems on Earth?
Answer:
Our results contrast with research conducted in protected areas that suggested human effects in the food web are primarily predator-mediated. Instead, human influence on vegetation may strengthen bottom-up predominance and weaken top-down trophic cascades in ecosystems.
Explanation:
Humans affect the different trophic levels in ecosystems on Earth through destroying it via activities such as habitat destruction, pollution etc.
What is Ecosystem?This refers to all the organisms and the physical environment with which they interact.
Humans have destroyed most of the trophic level through predator mediated activities but however have increased the producers through agricultural processes.

Read this Pulmonology Consult excerpt:On physical exam, the patient is alert. He takes occasional pauses when he says long sentences, but otherwise, he is not in any distress. He has an occasional cough during his exam. His skin is pink and dry, and his lips are moist. His heartbeat is regular in rate and rhythm, without a murmur. On lung examination, he has whispered pectoriloquy on the right side with decreased breath sounds. He does not have any retractions or nasal flaring noted. His liver and spleen are not large.According to the excerpt, what was found upon lung examination on the right side?A. "Whispered pectoriloquy" - a chest that protrudes like the keel of a ship when the patient whispersB. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is presentC. "Retractions" - reverberations in the chest when it is struckD. "Retractions" - a dull sound in the chest when it is struckE. "Whispered pectoriloquy" - a chest that is hollowed out when the patient whispers
Answer:
B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present
Explanation:
Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.
Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.
Whispered pectoriloquy is used to detect vocal resonance. It is used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.

1) You are studying the uptake of a certain molecule into cells that produce no ATP. You discovered
that it in fact does become transported into the cell. To further your research, your colleague
decides to do the same experiment but supplies the cell with ATP. He discovers that the cell
transports more of the molecule intracellularly.
a. Describe the difference in transport between your experiment and his. Explain. (10pts)
b. What characteristics must this molecule have in order to use both types of transport?
(10pts)
Answer:
Your cell use passive transport whereas your colleague cell use active transport.
Explanation:
There is a great difference in the type of transport between your experiment and his because you provide no ATP to the cell for transport means you use passive transport in which the cell moves molecules without the use of energy while on the other hand, your colleague provides ATP to the cell means the cell transports molecules with the use of energy so the cell use active transport. The characteristics of molecules have the presence of both type of cells which do both type of transport.

Answer:
The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?
Explanation:
The layers of the atmosphere are determined based on air temperature, the energy in the air molecules comes from the sun, which increases the temperature of the atmosphere.
What are the layers of atmospheres?There are different layers of the atmosphere. There are seven layers of atmosphere. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The sun is the only source of energy for the atmosphere. It provides heat or thermal energy and which is acquired by different molecules and these molecules convert this energy into other forms of energy.
Thus, the energy contained in the molecules of the air is derived from the sun, which raises the temperature of the atmosphere, which in turn determines the layers of the atmosphere.
