one of which rolls its dung balls during the day and rests at night. The other rolls its dung balls at night and rests during the day. These species will not breed because of Temporal isolation.
When two species are divided based on when they operate, it results in the phenomena of temporal isolation. The difference in their mating seasons or the time of day they are active could be the reason for this divergence. This type of isolation reduces the likelihood of interbreeding between the two species, which may eventually lead to speciation.Because two species of beetles in the provided question are active at separate times of the day and do not cross-pollinate, it can be said that these species are exhibiting a temporal form of isolation.learn more about Temporal isolation here: https://brainly.com/question/469933

________ is a postexercise snack that has been shows to increase muscle glycogen stores and protein synthesis. a. Cheese b. Almonds c. Chocolate milk d. Bananas e. Whole-grain tortillas
The correct answer is Option c (Chocolate milk).
What is a good post-workout snack?When you work out, your muscles use their glycogen energy stores. Some of the muscle proteins also get damaged, especially during strength workouts. Therefore, after workout it is important to consume protein in combination with moderate carbohydrate.A diet rich in carbohydrates increases endurance performance because of the extra store of carbohydrates in the muscles and liver, called glycogen.Chocolate milk has everything you need after a workout—carbs, protein, fluids and electrolytes. Low-fat chocolate milk contains a combination of carbohydrates and protein which is just right for refueling weary muscles.Cottage cheese is an excellent source of both whey protein and casein protein which replenish muscles.Almonds provide protein, fiber and healthy fats.Bananas reduce inflammation and replenish muscle glycogen stores, ultimately promoting quicker recovery.Whole-grain tortillas provide fiber and protein.Learn more about post-exercise snacks here:

What are the major mechanisms of epigenetic genome modification?
The major mechanisms of epigenetic genome modification are DNA methylation, histone modifications, and non-coding RNA-associated gene silencing.
DNA methylation is the process in which there is an addition of methyl groups to the DNA molecule. When there is the presence of methyl groups on a gene , it is turned off. Thus, no protein formation takes place from that gene.
Histone modification is the process in which histone proteins, can be modified by the addition or removal of methyl or acetyl groups. DNA is wrapped around histone proteins, and histone proteins can be modified by the addition or removal of methyl or acetyl groups. Due to these modifications. it affects how tightly DNA is wrapped around histones and genes can be turned off and on.
Non -coding RNAs control gene expression by sequence specific interactions with regulatory regions.

Cholera toxin locks the Gs subunit into an active state, in that GTP is bound and cannot be hydrolyzed back to GDP to turn off the subunit. What effect will cholera toxin have in the cell
Cholera toxin locks the G-subunit into an active state, in that GTP is bound and cannot be hydrolyzed back to GDP to turn off the subunit. This leads to a subsequent activation and increase in adenylate cyclase inside the cell. This increases the level of cAMP which leads to cytolysis of the cell.
The cholera toxin is released from a bacteria known as vibrio cholera. This bacteria is gram-negative and releases this toxin into the body which leads to manifestations like vomiting, increased heartbeat, watery diarrhea, cramps in the muscles and a low blood pressure. When this toxin is released into the body. The toxin activates adenylate cyclase and increases its level. This in turn increases the level of cAMP. This initiates a signaling cascade which effects the osmotic pressure of the cell. This leads to subsequent cytolysis of the cell.

What feature would easily distinguish schist and gneiss from quartzite and marble?
Foliation is much better developed in most schists and gneiss than in most quartzites and marbles.
The major contrast between schist and gneiss is that schist is made of mudstone or shale, whereas gneiss is made of micas, chlorite, or other platy minerals. While Marble and quartzite the major difference is that marble is composed of calcite whereas quartzite is composed of quartz.
Schist is identified by its flat and large sheet-like grains it also has flat and elongated minerals such as talc or micas. Gneiss is a metamorphic rock formed by changing schist, granite, or volcanic rocks through intense heat and pressure.

Hutchinson's definition from 1957 is the finest one that can be found. An n-dimensional hypervolume known as an ecological niche is where a species can sustain a livable population. The tolerance boundaries must be understood in order to comprehend this. These are the constraints that place limits on the organism. For instance, if the outside temperature exceeds 55 °C, a dog will perish. Therefore, 55 °C is one temperature that a dog can tolerance limits for temprature in the dog is therefore 55°C.
specific niches ?
Systematics, ecology, conservation, public health, and other fields are increasingly using ecological niche modeling, or the assessment of the dimensions of a species' basic ecological niche, to forecast its worldwide spread. This method frequently (necessarily) relies on data that consists solely of presence records. Numerous modeling techniques have been developed in recent years to estimate these connected representations of a species' ecology, distributional biology, and evolutionary history. Despite this, many of these techniques lack a formal foundation in ecological and evolutionary theory. In this article, we lay forth a formal foundation for the collection of methods known as "ecological niche modeling," examine some real-world examples of how they can be applied, and explain how the results should be interpreted.

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enzyme important for efficiency in pcr?.
The use of a thermophilic DNA polymerase such as Taq polymerase prevents the denaturation of the enzyme during the heating that is important to separate the newly synthesized strand. So using this enzyme simplifies the PCR technique and increases its efficiency.
Taq DNA polymerase is highly efficient, when it reaches the optimum temperature, it becomes fully functional. It also has a half-life of over two hours (at 92°C), high amplification capacity, and it can add upto 150 nucleotides per second. It is "special" enzyme because it comes from the bacterium Thermus aquaticus, which lives in hot springs. It is therefore thermostable even at high temperatures, while other polymerases (e.g. E. coli) are not.

Understanding the impact of activity or exercise includes concentrating on unambiguous changes in muscles, cardiovascular, and neurohumoral frameworks that lead to changes in practical limit and strength because of aerobic exercise or strength. To work, our muscles need energy, which is delivered by chemical and hormonal cycles. During the 1910s Archibald Hill framed these cycles by investigating muscles from frogs. Contrary to the predominant view that mechanical development and chemical cycles were equal arrangements, Hill had the option to appear through estimations of intensity created by the mechanical cycles that these were postponed corresponding to the movement.

There are 3 possible genotypes: NN, MN, or MM. In a group of 500 people, the frequency of genotype NN is 40%. How many individuals would you expect to have the MN genotype
235 are the Individual numbers that would expect to have the MN type of genotype.
There are two equations necessary according to Hardy-Weinberg Equilibrium:-
p + q = 1
p² + 2pq + q² = 1
Let,
NN= p
NM=2pq
MM=q
So, according to the question, the frequency of genotype NN is 40%
40% of 500 = [tex]\frac{500*40}{100} = 200[/tex] Numbers of individuals
Frequency of individuals p = [tex]\frac{Numbers of individuals}{Total populations}[/tex] = [tex]\frac{200}{400} = 0.4[/tex]
Find p² by taking the square root of p.
√(p) = √(0.4)
= 0.632
So, pp + qq = 1
qq = 1 - pp = 1 - 0.63
q = 0.37
The allele frequencies in the population are known, now finding the frequency of heterozygous genotype.
By Multiplying 2 × p ×q to get heterozygous genotype
2pq = 2 × 0.63 × 0.37` = 0.47
