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.

La Selva Biological Station and the Braulio Carrillo National Park in Costa Rica are an example of La Selva Biological Station and the Braulio Carrillo National Park in Costa Rica are an example of use of island biogeography theory in guiding conservation. poor planning in conservation efforts. use of corridor theory in guiding conservation. use of metapopulation dynamics in guiding conservation.
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).
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.

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.
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.

It is the label used to show which animals have been given hormones and artificially-made nutrients.
ООО
It deals with synthetic or superficial genes and traits like color, markings, size, and speed.
It is the opposite of natural selection, in which organisms adapt to their environments without human intervention
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.

5. The reactants and products for respiration are exactly the
same for a plant cell and an animal cell, the difference is
the _______
of the reactants.
Answer:
Source
Explanation:
Respiration, which occurs in all living organism, is the metabolic process by which organisms obtain energy (ATP) via the breakdown of their food substances.
The process of respiration in plant and animal cells is similar in the sense that reactants and products for respiration are exactly the same for both cells. The reaction is as follows:
C6H12O6 (glucose) + 6O2 = 6CO2 + 6H2O
The difference between this process in plant and animal cells is the SOURCE of the glucose or food molecule that is broken down. Plants get their food from PHOTOSYNTHESIS (autotroph) while animals get theirs by feeding on other organisms (heterotroph).

Suppose we have access to the four nucleotides which compose DNA: A, T, C and G. Placed into a sequence with one another, they form a code which can be read by the cell to provide a blueprint for the creation of proteins. When forming a sequence of three nucleotides, the sequences TAA, TAG, and TGA are codes to tell the cell to stop reading the DNA. Assume each sequence of nucleotides is equally likely to be formed.
A. How many possible ways are there to form a sequence of three nucleotides? - 64
B. Of the possible ways to form a sequence of three nucleotides, what is the probability to form a stop sequence? = 0.0469
C. What is the probability that a sequence that is not a stop sequence is formed? 64-3 = 61 61 = 0.983
D. For a three-nucleotide sequence, G is engineered to be in the third place. For the remaining two nucleotides in the sequence, C cannot be in the second place (for example CTG is allowed but not TCG). How many sequences can be formed?
E. Of the number of sequences found in Part D, what is the probability that a stop sequence is formed?
Answer:
The correct answer is :
A. we know there are four nucleotides and three sequence makes a triplet code then total possible ways are:
4^3 = 4×4×4= 64 ways.
B. The stop codons by 64 amino acid or triplet codes: TAA, TAG, and TGA then the probability would be = 3/64 = 0.0469
C. the probability that a sequence that is not a stop sequence is formed = total minus probability of stop codons:
64-3 = 61
61/64 = 0.953
D. G at end place and c should not be in the middle then:
the codes will be =
ATG
AGG
AAG
TTG
TGG
TAG
CTG
CGG
CAG
GTG
