Functional regeneration of axons occurs more frequently in the peripheral nervous system (PNS) than in the CNS because of the
Functional regeneration of axons occurs more frequently in the peripheral nervous system (PNS) than in the CNS because of two main reasons which are-
The environment in the central nervous system is not suitable for the regeneration or repair of axons.The axons of the neurons in the CNS cannot upregulate genes for the growth or regeneration of the axons. Whereas the axons in the PNS can upregulate these genes to a much greater extent than the CNS.The central nervous system(CNS) and the peripheral nervous system(PNS), are the two branches of the nervous system in the body. The central nervous system consists of the spinal cord and the brain. While the peripheral nervous system consists of the nerves and neurons that arise from the spinal cord and the brain. It is difficult for axons to repair themselves in the central nervous system because these axons are present in and around the main structures that control the entire nervous system.

A separation technique that can detect proteins in a complex mixture with the use of antibodies directed against a protein of interest is
Northern blotting is the separation technique that can detect proteins in a complex mixture with the use of antibodies directed against a protein of interest.
Commonly used protein separation techniques include ion exchange chromatography, affinity chromatography, dialysis, ultrafiltration, size exclusion chromatography, and electrophoresis [sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), Isoelectric point electrophoresis, and chromatographic electrophoresis] are included.
Northern blot is a laboratory analysis method for testing RNA. In particular, purified RNA fragments are separated from biological samples (such as blood and tissue) by passing through a gel or matrix like a sieve with an electric current. This allows small fragments to move faster than large fragments.
Northern blotting is named because it resembles Southern blot, the first blotting technique named after biologist Edwin Southern. The main difference is that Northern blots analyze RNA rather than DNA.

what do you conclude from the study of embryos?
We can get a glimpse into an organism's evolutionary history through embryology. As an illustration, consider terrestrial vertebrates, which include mammals, birds, amphibians, and reptiles. There are numerous parallels between fish embryos and other animal embryos when we examine the early stages of the development of various groups of animals. All of these animal groups have gill arches in their developing embryos. These develop into functioning gills in fish embryos. They go on to develop into the morphological structures that make up our ears in the majority of terrestrial animals. This helps us understand how certain animal traits may have evolved from more basic ones. Cases like these add to the body of evidence showing that lobe-finned fishes are the ancestors of terrestrial mammals.
How does embryology prove evolution happened?Embryology offers no proof. The descriptive study of embryos is known as embryology. It has been discovered that embryos from all species have parts that should naturally belong to less advanced organisms. By the time the embryo develops into a fully formed live being, those structures have either vanished or changed into something more adapted to the particular environment. Because the ancestors of the species whose embryo we are investigating truly possessed such qualities and made use of them, we refer to them as atavistic features, from the Latin term for forefather. These traits are numerous. I'll name one. An embryonic human resembles an embryonic monkey almost exactly, down to the tail. Human genes guarantee (nearly invariably) that the tail resorbs, leaving just a little remnant with five tail bones, the coccyx, whereas the genes of the monkey ensure that it is still present at birth. Human embryos, as well as monkeys and many other animals, feature fish-like gill clefts. In our situation, they were born as more beneficial organs.
Therefore, embryology detects phenomena that call for justification. They would just be bizarre if they weren't. Every creature's embryology may be thoroughly examined to build a comprehensive picture that is perfectly compatible with evolution. That is but one piece of the puzzle of findings and information that support the hypothesis (i.e., explanation) of evolution.
To be fair, I should point out that there are alternative hypotheses that might account for the embryological findings as well as the variety and at the same time linear similarity of all living things, whether ancient and modern. Accepting these alternative explanations allows you to forget about learning anything and skip over years of fruitless inquiry in the fields of embryology, paleontology, biology, and anatomy. It also greatly simplifies the process of comprehension. All you need to do is put your trust in the scientifically illiterate authors from two centuries ago who, through no fault of their own, may have known nothing about biology, anatomy, or physiology because those fields didn't even exist at the time. As a result, they could have observed nothing and conducted zero research.
That does however require you to understand that the tens of thousands of scientists who have carried out all the work over the past 200 years have all been frauds, and that there is a massive global conspiracy devoted to disseminating lies and misinformation in order to enrage a small American sect known as creationists. even if the majority of those scientists practice religions similar to those of everyone else. Why? It must be to exact revenge on those hateful Christians, who have undoubtedly caused them terrible, unnamed suffering.

What is the study of embryos?Embryology is a branch of science that focuses on the conception, development, and growth of the embryo. For example, all vertebrate embryos have tails and gill holes.
It focuses on the prenatal stage of development, which begins with gamete creation, fertilization, zygote formation, embryonic and fetal development, and human birth.
The two main processes at work are growth and differentiation. These lead to the body's formation of distinctive tissues and organs that are specialized to perform certain activities.

Why f1 particles are named f1 particles
The F1 fraction derives its name from the term “Fraction 1” and FO (written as a subscript letter “o”, not “zero”) derives its name from being the oligomycin binding fraction. Oligomycin, an antibiotic, is able to inhibit the FO unit of ATP synthase.
hope this helps u :)
F1 particles are named so because they were first identified as the first generation of particles in a process known as "fractionation."
This process involves the separation and isolation of cellular components based on their size and density using centrifugation.
During experiments with mitochondria, scientists observed that when mitochondria were subjected to fractionation, two distinct types of particles were obtained: F1 particles and F2 particles.
F1 particles were found to contain the ATP synthase enzyme responsible for ATP synthesis in cellular respiration. Hence, they were named "F1 particles" to denote their status as the first fraction of particles isolated during this particular experiment.

Assume that you have discovered a new chemical mutagen that modifies guanine so that it mispairs with thymine when thymine is in the template DNA strand during DNA replication. However, this mispairing is limited to when the modified guanine is being added to the newly replicating DNA strand. When the modified guanine is in the template DNA strand it always pairs normally, with cytosine being added to the growing newly synthesized strand. What type of mutation would you predict would be caused by the new chemical mutagen
A-C base substitution mutation will be caused by the new chemical mutagen.
When A is in the template strand during the first round of replication, G is added to the new daughter strand as it pairs to A due to mispairing. It is assumed that this mispairing only occurs when the freshly duplicated strand is being joined to the modified guanine. C is added to the opposing strand during the second round of replication, when the daughter strand that contains G serves as a template for replication. Therefore, C has replaced A in the diagram.
