Which discovery supports the hypothesis that evolution of the lactase-persistence trait was driven by the use of milk in pastoralist cultures
The lactase-persistence mutations are roughly as old as the oldest milk-holding vessels or pots.
Lactase persistence:
Lactase persistence is an example of natural selection, which can cause some humans to continue the activity of the lactase enzyme in adulthood also.
The hereditary examinations and studies propose that the established mutation related to lactase persistence began a long time back, in populaces that started domesticating and dairy cultivation during the Neolithic age when pastoralist populaces started to utilize milk for their livelihood. As found and studied that “the lactase-persistence mutations are roughly as old as the oldest milk-holding vessels.” The cultural and social activities of dairying and drinking non-human milk gave an environment wherein lactase persistence was favorable. DNA proof demonstrates that mutation in the lactase gene emerged in these populaces around a similar time.

The action potential spreads through an axon by Group of answer choices depolarizing adjacent membrane to threshold, triggering another action potential. inflow of potassium ions and outflow of sodium ions. a non-decremental of graded potential. a decremental of graded potential.
The action potential spreads through an axon by depolarizing adjacent membrane to threshold.
K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.learn more about action potential here: brainly.com/question/6705448

Answer:
option C
option C
Explanation:
we know that gravity is strongest when two large objects are near each other--so, when the asteroid reaches point C (which is shown to be closest to the sun), the pull of gravity will be greatest.
We also know that the attraction/pull of gravity slows down objects, so, the asteroid will be going slowest at its point of strongest gravity--which we have determined to be point C

What are the key important things you need to know about dna
For revision notes
Answer:
Nucleic acids are the organic materials present in all organisms in the form of DNA or RNA.
These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and phosphate groups that are linked by different bonds in a series of sequences.
Explanation:
“DNA is a group of molecules that is responsible for carrying and transmitting the hereditary materials or the genetic instructions from parents to offsprings.”
DNA is known as Deoxyribonucleic Acid. It is an organic compound that has a unique molecular structure. It is found in all prokaryotic cells and eukaryotic cells.
The four roles that DNA plays in the cell are:
(1) storage of information via the genetic code so that cellular processes can be initiated and maintained.
(2) the generation of genetic variation through mutation and recombination.
(3) The copying and replication of genetic information so that it can be passed onto daughter cells. It is this function that makes DNA the molecule of inheritance.
(4) gene expression. The transcription and translation of genetic material to produce proteins, enzymes and other gene products necessary for growth and life.

You are comparing two samples of the octopus genome, one from an octopus that can make ink (sample 1), and one from an Octopus that can’t make ink (sample 2). You notice the one who can’t make ink has a mutation. Sample 1: ATTACAGTACTGGCA Sample 2: ATTACAATACTGGCA
Looking at the sequences carefully you determine it is a __________ mutation.
A. Insertion
B. Deletion
C. Substitution
D. Inversion
The mutation is the modification or change in the nucleotide bases of the genetic material. From the sequence of the octopus, it can be said that it is a substitution mutation. Thus, option C is correct.
What is a substitution mutation?A substitution mutation is the type of mutation where the single nucleotide base is substituted with another base like in sample 2 of the octopus incapable of producing ink, the base G is substituted by base A.
It is not an insertion mutation as no new base is added nor it is a deletion as no base was removed from the original sequence. It also is not an inversion mutation as no two bases have switched their places.

After a mass extinction event, the organisms that survive face unique circumstances in which there are fewer predators and more resources available. This is termed Adaptive Radiation.
Adaptive Radiation
Adaptive radiation, which occurs when an environmental change makes new resources available, modifies biotic interactions, or creates new environmental niches, is a process in evolutionary biology wherein animals rapidly diverge from an ancestral species into a variety of different forms.This process culminates in the speciation and phenotypic adaptation of numerous species with various physical and physiological features, all descended from a single ancestor.

If mutant HMGN2 proteins were unable to bind their substrate and then erroneously mobilized to nucleoli, these proteins would be found in the sites of Ribosome production.
In this case, mutant HMGN2 proteins deploy inadvertently to nucleoli. The nucleolus, a bulky, globular structure inside the nucleus of eukaryotic cells, houses ribosomal DNA. Here, the pre-ribosomal RNA (rRNA) gene is solely translated into a single template that is then processed to produce mature rRNA by RNA polymerase I. As a result, the nucleolus is the only location where RNA polymerase I can work.Additionally, ribosomal subunit maturation and assembly take place in the nucleolus. The cytoplasm produces ribosomal proteins from mRNA, which are then carried into the nucleolus where they interact with newly produced rRNA to generate the precursors to the 40S and 60S subunits.learn more about HMGN2 proteins here: https://brainly.com/question/884041

The main immediate source of ATP is creatine phosphate.
The answer is option b.
Creatine phosphate gives about the first 15 seconds of ATP at the beginning of muscle contraction.
Anaerobic glycolysis produces small amounts of ATP within the absence of oxygen for a quick duration. Aerobic metabolism makes use of oxygen to provide much greater ATP, permitting a muscle to work for longer intervals.

Red blood cells become crenated in a(n) ____________ solution. hypertonic hypotonic hydrostatic isotonic
Red blood cells become crenated in a hypertonic solution. Therefore, option (A) is correct.
In a hypertonic solution, solutes outside red blood cells are greater than within. To equalise the concentration gradient, red blood cells release water. Red blood cells shrink and become crenated.
In a hypotonic solution, solutes outside red blood cells are lower than within. Hemolysis occurs when water enters cells, swelling and perhaps bursting them.
Solute concentrations outside and within red blood cells are equivalent in isotonic solutions. Water does not migrate, and red blood cells remain normal. The term "hydrostatic" does not refer to a red blood cell-affecting solution in a hydrostatic solution. Therefore, option (A) is correct.
