A farmer often sprays a certain kind of insecticide, a chemical that kills insects, on his plants to prevent locust bugs from eating all of his corn crops. One day there was a random change in the sequence of DNA in a locust egg cell. When the egg cell hatched, the locust was resistant to the insecticide (it would not be killed by it). Since that locust could survive and reproduce, natural selection occurred until the entire population evolved to become resistant.
A) Identify the variation that existed in the insect population. _________________________________
B) Identify the process that created this variation. _________________________________
C) Explain why the variations in the insect population would be passed on to the next generation.
D) Is this locust population likely to survive, why or why not?
Answer:
as they were living in that environment they adopted it and were able to in it ; the population was able to survive because they adopted it
How would the dynamic of an ecosystem and rate of evolution change there was an unlimited supply of resources, including food, space and water?
Answer:
The population will be large and evolution process is slow.
Explanation:
There will be large population of organisms present in the ecosystem and slow rate of evolution when there is unlimited supply of resources such as food, space and water etc because these resources are needed by the organisms to increase their population. There is also a slow rate of evolution when there are plenty of resources because limited resources also increase the chance of evolution and when there is no competition among organisms, the rate of evolution slower down.
When living things die, why are there only bones remaining after some time?
Answer:
When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.

The effect of cholesterol on membrane fluidity at physiological temperatures is to Choose one: A. prevent lateral movement of phospholipids and thereby decrease membrane fluidity in that region. B. maintain membrane fluidity due to exclusion of saturated glycerophospholipids. C. rigidify membranes by forming a complex that bridges the inner and outer leaflets. D. maintain membrane fluidity through its disruption of fatty acid packing.
Answer:
The correct answer is D. maintain membrane fluidity through its disruption of fatty acid packing.
Explanation:
Cholesterol is a steroid lipid and is a constituent of biological membranes. It regulates the fluidity of the membrane (so, option C is not correct). Since cell membranes are composed of another type of lipids, the phospholipids, which form a bilayer, cholesterol distributes between the phospholipid tails and avoids these molecules pack each other forming rigid clusters. Thus, the option which better explains the effect is D. maintain membrane fluidity through its disruption of fatty acid packing.

The dwarf phenotype is recessive to the tall phenotype in pea plants. When one tall plant and one dwarf plant are crossed together, 50% of their offspring are tall, and the other 50% displays dwarfism. What is the genotype of each parent in this cross?
Answer:
Tt (heterozygous tall) and homzygous short (tt)
Explanation:
This question involves one gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (tt). This means that dwarf phenotype is recessive to the tall phenotype in pea plants.
According to this question, a tall plant and a dwarf plant (tt) are crossed together. 50% of their offspring are tall, and the other 50% displays dwarfism. This is an equal ratio. Since the dwarf plant can only be "tt", the tall plant must be heterozygous "Tt" to be produced.
Hence, a cross between Tt vs tt will produce ½tall plants and ½short plant.
How to use informal assessment effectively to prepare for examination
Answer:
Kindly check explanation
Explanation:
The use of informal assessment while preparing for an examination could take various forms. Informal assessment include the use of actual grading of a set of questions which one decides to test his/her knowledge on in other to check or evaluate performance. Similarly, one may employ the use of a colleague or friend to set out a few likely questions from the subject or the use of previous test or examination questions to ascertain how well one has grasped or covered in the subject. Also, one could personally reminisce on the areas covered, frame likely questions in reasoning and check if the appropriate response could be proffered.
The phenotypic variation in behavior between the two populations can best be described as resulting from sexual selection sexual selection A natural selection natural selection B artificial selection artificial selection C genetic drift
About the question:
I failed to find the complete question. However, I propose the following answer and explanation according to the given statement.
Answer:
Natural selection
Explanation:
Natural selection is the product of the interaction between phenotype and environment, which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population.
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
In many cases, adaptations -as a result of natural selection-, can be correlated to environmental factors or selective pressures applied by other organisms or habitats. These organisms might change or modify their habits according to the environmental pressures that are acting on them. Natural selection favors these new habits and behavior. The better an organism can behave in an environment, the higher chances to survive.
In the exposed example, if assuming that these two populations belong to the same species, they might behave differently from each other if they are, for instance, occupying different niches, changing their feeding habits, competing with other species, among other factors. If these two groups are separated in space and/or time, they might receive different environmental pressures that lead them to change the original behavior to a new one. And as both groups are separated, those pressures probably differ, modeling a behavior adapted to a specific niche.
Answer:
The correct answer is natural selection.
what elements cycle between living and non living organisms?
Explanation:
The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Answer:
use of corridor theory in guiding conservation
Explanation:
Conservation corridors, also known as green corridors, are small fragments of wildlife habitat that are installed to connect fragmented habitats. It is believed that green corridors can maintain healthy genetic diversity levels by connecting habitat patches that otherwise would be isolated (i.e., these corridors increase gene flow between isolated populations). Thus, green corridors are used to alleviate the harmful effects of habitat fragmentation on population viability. Species that make use of green corridors can be classified into passage users, which occupy corridors during brief periods of time, and corridor dwellers, which occupy corridors during long periods (even all life).

O It alludes to the process of artificial insemination, a process of unnaturally planting a fertilized egg.
Answer: it deals with synthetic or superficial genes and traits like color, markings, size, and speed.
Explanation: a good example of artificial selection is breeding dogs. people mix breeds to get these kinds of quality’s.
Artificial selection is the opposite of natural selection, in which organisms adapt to their environments without human intervention. So, the correct option is C.
What is Artificial selection?Artificial selection, commonly known as selective breeding, is the intentional breeding of particular plants or animals by humans to advance certain desirable traits. On the other hand, natural selection occurs in the wild when organisms with favorable characteristics are more likely to survive and reproduce.
The term "artificial" in artificial selection refers to deliberate human manipulation of the reproductive process as opposed to allowing natural processes to occur. The use of nutrition, hormones or artificial insemination is not mentioned. A wide variety of traits, including color, markings, size, movement, and other physical or behavioral characteristics, are possible through artificial selection.
So, the correct option is C.
