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.

Answer: 1. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. 2. The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. A bacteriophage, or bacteria virus, injects its DNA into the bacteria. ... The DNA is then replicated when the bacteria undergo cell division. 3. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates. ... It then removes itself from the host cell's DNA and enters the lytic cycle. The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse). 4. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. brainliest?

Cichlids, a type of fish, were introduced to a lake around 200 years ago. Over the years, the fish have developed into two distinct groups. One group stays in the main lake and the other group resides in the streams that flow into it. Both groups of cichlids breed in the same streams at the same time of year. However, the groups are splitting into two genetically and physically different types of fishes. How would you classify this type of speciation
Answer:
sympatric speciation
Explanation:
Different sympatric species have the same closest ancestor and live in the same area but inhabiting different niches.
The steps for sympatric speciation are:
An ancestral species inhabit a geographic area.With time, different populations of the same species occupy different niches or microhabitats in this general area. As the microhabitats are different, they have different environmental pressures that are acting on each population.These pressures lead to the origin of differences between groups, which need to adapt to each environmentEach population suffers genetic changes due to environmental conditions. These changes are inheritable.With time, these differences drive to the final complete divergence of populations, becoming different species and reproductively isolated.In sympatric speciation, the interruption of genetic flow must be fast, and there must be differences in niches so no species can compete and displace the other species. Speciation occurs in the same distribution area of the original species. The new species originate in a place with no physical barriers but different environmental pressures.
In the exposed example,
The introduced Cichlid fishes 200 years ago → Original species and the common ancestor between the new derivated speciesThe lake → general geographic areaThe main lake and the streams → Microhabitats or niches with different pressures eachThe groups are splitting into two genetically and physically different types of fishes. They do not mate. There is no genetic flow between groups. → Speciation process.What is the answer please help no links I will report

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.
During a hectic moment in the ER, Robin received a needle stick from a hyperdermic used on the patient. She later was diagnosed with Hepatitis B. This would be an example of what type of transmission?
Answer:
Fomite Transmission
Explanation:
The type of transmission used as an example in this scenario would be Fomite Transmission. This is when an inanimate object that has been in contact with a disease becomes contaminated and then comes into contact with an individual. In this scenario, once the needle was used on the patient that had Hepatitis B it immediately became contaminated. Then by accidentally being stuck by the needle, Robin became infected as well as the disease was transmitted from the needle into her bloodstream.

d. G-A-C-A-T-C-C-G
Which sequence represents an inversion
mutation?
Answer:
1. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the complementary sequence is C-T-G-T-A-A-G-G-C (a).
2. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the insertion sequence is G-A-C-G-A-T-T-C-C-G (b).
3. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the deletion sequence is G-A-C-A-T-C-C-G (d).
4. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the inversion sequence is G-A-C-T-A-T-C-C-G (c).
Explanation:
The complementary sequence of DNA is a sequence of complementary nucleotides. The complement is a nitrogenous base that correctly pairs with the base that is given. In DNA, Adenine (A) correctly pairs with Thymine (T), and Guanine (G) with Cytosine (C). Therefore, the complement of A is T, and of C, is G.
The given sequence complement would be C-T-G-T-A-A-G-G-C since it's a sequence of bases that correctly pairs with the given sequence, G-A-C-A-T-T-C-C-G. [ G-A-C-A-T-T-C-C-G | C-T-G-T-A-A-G-G-C ] Notice that the first base in the sequences is G and C respectively. The next two are A and T. The paring is such that C complements G, and that A, T.
2. An insertion sequence is one in which there is an extra added nucleotide or codon. [ G-A-C-A-T-T-C-C-G ] Notice that there are three Triplets in this sequence. In a case where there is an extra nucleotide(s) or codon(s), such is termed an insertion mutation. When the given sequence is compared with the sequence in option b, G-A-C-G-A-T-T-C-C-G, you can observe an extra nucleotide [G - the fourth letter in the sequence]. Therefore, this sequence is called an insertion sequence.
3. Deletion mutation is an error in the DNA replication process that removes a nucleotide(s) from the genome. Hence a sequence that has a nucleotide(s) removed from the original sequence is called a deletion sequence. With the given sequence, G-A-C-A-T-T-C-C-G, the deletion sequence to this is G-A-C-A-T-C-C-G. [G-A-C-A-T-C-C-G ] Notice that one of the nucleotides, T, is missing.
4. Inversion mutation is a chromosome rearrangement in which a chromosome is reversed end to end. This involves breaking and rearrangement within a sequence. With the given sequence, G-A-C-A-T-T-C-C-G, an inverted sequence is G-A-C-T-A-T-C-C-G. [ G-A-C-T-A-T-C-C-G] Notice the first two nucleotides, of the second codon (....-T-A-T-...). The original sequence has....-A-T-T-...., but the new sequence here has...-T-A-T-.... Suggesting that the first two nucleotides were broken and rearranged end to end.
While having dinner, your little sister says she learned about energy and matter at school today and that the food you are eating and the energy you receive from it have been consumed and used previously. Your family is surprised by this and since you are the older sibling, they have asked you to explain whether your little sister is correct or not.
5-8 Complete sentences
Answer:
She is correct
Explanation:
The reason why she is correct because everything had come from something. For example, if a farmer is eating an apple, takes the seeds out, and plants them, the apple you are eating right now came from the farmer's apple. This means that it had been used previously. An example of it being consumed previously is if an animal had eaten an apple, put its feces on the ground, and left, the seeds from the apple will eventually grow. This could have been how your apple has grown. This could be an example of most foods we eat.
How is the formation of RNA similar to DNA replication?
Answer:
Both DNA replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while the DNA replication makes another copy of DNA. Both the process is involved in the production of new nucleic acids- DNA or RNA.
Explanation:
The formation of RNA is similar to DNA replication because both processes require an analogous enzyme (Polymerase).
What is DNA replication?DNA replication refers to the process of duplication of the genetic material before cell division (either mitosis or meiosis).
DNA replication requires different enzymes such as DNA polymerase, ligase, RNA primase and topoisomerase. Moreover, RNA replication or transcription also requires a nucleotide polymerase (RNA pol), which uses DNA as a template to generate complementary RNA.In conclusion, the formation of RNA is similar to DNA replication because both processes require an analogous enzyme (Polymerase).
