1. Reproductive isolation is essential for population divergence. The mechanisms of reproductive isolation are essential for speciation which is the process of development of new species from preexisting species.
Due to reproductive isolation individuals of the same population will acquire different types of genetic variations and mutations such that males and females of the isolated populations cannot reproduce with each other.
3. Mechanisms of reproductive isolation are temporal isolation, behavioural isolation, gametic isolation, ecological isolation, mechanical isolation, hybrid inviability, hybrid sterility and hybrid breakdown.
4. Species populations within the same habitat become reproductively isolated in sympatric speciation. This speciation is a resultant of polyploidy where an offspring develops with twice the number of chromosomes.
5. Allopatric speciation is also called geographic isolation and it is the most common type of isolation. A geographical barrier separates individuals of a species and the separated groups develop into new species.
Calculate the calories for a flour tortilla that contains 3 grams of fat, 2 grams of protein, and 17 grams of carbohydrate.
Answer: 103 calories
Explanation:
We know that carbohydrates contain 4 calories per gram, protein contains 4 calories per gram, and fat contains 9 calories per gram.
Given : A flour tortilla contains : 3 grams of fat, 2 grams of protein, and 17 grams of carbohydrate.
calories in 3 grams of fat = 3 x 9 = 27 calories.
calories in 2 grams of protein = 2 x 4= 8 calories.
calories in 17 grams of carbohydrate = 17 x 4 = 68 calories
Then , the total number of calories in flour tortilla will be
= calories in 3 grams of fat+ calories in 2 grams of protein +calories in 17 grams of carbohydrate
= 27+ 8+68 calories.
=103 calories.
Hence, there are 103 calories for a flour tortilla that contains 3 grams of fat, 2 grams of protein, and 17 grams of carbohydrate.
To calculate the calories in a flour tortilla, multiply the grams of each macronutrient by the number of calories per gram for that nutrient. Then, add up the calories from each macronutrient to find the total calories.
Explanation:To calculate the calories in a flour tortilla, we need to know the number of calories per gram for each macronutrient. Fat contains 9 calories per gram, protein contains 4 calories per gram, and carbohydrates contain 4 calories per gram.
Given that the tortilla contains 3 grams of fat, 2 grams of protein, and 17 grams of carbohydrates, we can calculate the total calories as:
Calories from fat = 3 grams x 9 calories/gram = 27 calories
Calories from protein = 2 grams x 4 calories/gram = 8 calories
Calories from carbohydrates = 17 grams x 4 calories/gram = 68 calories
Total calories = calories from fat + calories from protein + calories from carbohydrates = 27 calories + 8 calories + 68 calories = 103 calories

Seeing a snake, and then simultaneously running away from it and becoming frightened, is the sequence of events postulated by ________ theory. a) Plutchik's the Cannon-Bard b) Schachter-Singer c) James-Lange.
Answer:
A) the cannon bard theory.
Explanation:
the cannon bard theory is an emotion that reflects that trigger feelings and physical reactions at the same time. in this specific example fear would be a feeling and running would be a physical response. could also be described as fight or flight response.
Seeing a snake and then simultaneously running away from it and becoming frightened is the sequence of events postulated by Plutchik's Cannon-Bard theory. So option A is correct for the statement.
What are flight and fright responses?Plutchik's Cannon-Bard explained that both the emotions and the physical activities occur simultaneously in some instances. An example is seeing a snake and then simultaneously running away from it and becoming frightened.
Seeing a snake initiates a danger feeling, and as a result, the running starts, which is a physical activity. In such a flight-and-fright situation, many hormonal activities change in the body. The sympathetic nervous system regulates different organs, such as the heart and breathing rate, in such a situation. It also activates muscle functions in order to avoid situations such as running, etc. At the same time, other, less necessary functions of the body slow down, such as digestion.
Hence, seeing a snake and then simultaneously running away from it and becoming frightened is the sequence of events postulated by Plutchik's Cannon-Bard theory. So option A is correct for the statement.

Answer: (d) e^12
Explanation:
The relationship between the standard free energy change, ΔG, and the equilibrium constant, K at a particular temperature is represented Using the formula ΔG = -RTlnK, where G = -30, RT = -2.5 and [Pi] = 1
lnK = ΔG/-RT
lnK = -30/-2.5
lnK = 12
taking exponents of both sides
e^(lnK) = e^12
K = e^12
Dogs are widely used by the police as biological recognition systems to detect drug smuggling and drug caches. Yet recent evidence suggests that insects, rather than mammals, might be used more effectively in this capacity. In the 1950s, German biologist Dietrich Schneider developed the first method that enabled researchers to record activity in insect olfactory nerves and to identify the compounds or class of compounds that trigger a particular behavioral response. The position of the insect olfactory organs on the surface of its body allows for direct investigation of the system’s response. Schneider’s technique formed the foundation of an olfactory detection system based upon insects, a system that is at least as effective as the ones based upon mammals.Insects have olfactory systems that are very similar to those of vertebrates. Insects first detect odors via finger-like protuberances on the antenna, called olfactory sensilla. The odorant molecules pass through pores in the outer cuticle of the sensilla and become attached to an odorant-binding protein. This protein carries the hydrophobic molecules through the lymph fluid found inside the cell and attaches them to receptors on the dendritic projections of a sensory nerve cell. Finally, these receptors send signals to the central nervous system, allowing researchers to detect and interpret the responses.It can be inferred from the passage that insects would be less useful for helping researchers to detect drugs if which of the following were true?A) They were as accurate as, but not more accurate than, dogs in detecting drugs.B) Insect olfactory systems did not deliver odorants to nerve cells, as vertebrate olfactory systems do.C) Dietrich Schneider did not develop the first method that enabled researchers to record the activity in insect olfactory nerves.D) They did not have finger-like protuberances for detecting odors.E) The signal sent to the insect’s central nervous system did not allow researchers to classify the compound that triggered the response.
Answer:
B. Insect olfactory systems did not deliver odorants to nerve cells, as vertebrate olfactory systems do
Explanation:
if insect olfactory system did not deliver odorants to the nerve cell, there will not be any basis for their use in detecting drugs.
A flat, wide, white, fibrous sheet of connective tissue that attaches a flat muscle to a bone or to deep muscles is known as a/an ____.

Aponeurosis
Explanation:
Aponeurosis refers to the connective tissue elements that extend as a broad, flat sheet. Therefore, an aponeurosis refers to a sheet-like tendon that joins one muscle with another or a muscle with bone. Aponeuroses are the extensions of connective tissue that go beyond muscle fibers. They are different from tendons in shape. An aponeurosis is wide and flat. For example, epicranial aponeurosis is present at top of the skull between the frontal and occipital bellies of the occipitofrontalis muscle.
An aponeurosis is a flat, wide, white, fibrous sheet of connective tissue that attaches a flat muscle to a bone or to deep muscles.

With regard to the functioning of the thyroid gland, which is an essential element for the manufacturing of thyroxine and triiodothyronine?
Answer:
The correct answer is- iodine
Explanation:
Thyroid glands is an important endocrine gland of the body which release hormone called thyroid hormone in the blood. It plays an important role in metabolism, brain development, and function, muscle control, etc.
The active form of thyroxine is triiodothyronine and the formation of thyroid hormone requires the availability of iodine. Four iodine atoms are present in thyroxine and 3 is present in triiodothyronine. Without iodine, they can not be produced.
Therefore iodine is the essential element that is required for the manufacturing of thyroxine and triiodothyronine.
Steroid hormones exert their action by ________. A. entering the nucleus of a cell and initiating or altering the expression of a gene B. binding cell receptors and initiating cAMP activity C. entering the cell and activating mitochondrial DNA D. activating the hypothalamic release of regulating hormones
Answer:
The correct option is A. Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.
Explanation:
Steroid hormones are derived from cholesterol and regulate multiple biological processes. All steroid hormones exert their action by crossing the plasma membrane and by binding with their respective intracellular receptors. They stimulate cell growth in a very different way, their lipophilic nature gives them the ability to cross lipid barriers, so, without the need for extracellular signals, these hormones can easily enter the cell, cross the cytoplasm and reach the nucleus. There they bind to specific receptors that are associated with DNA promoter regions, modifying their structure and promoting the expression of the genes under their control.
Steroid hormones work by entering the nucleus of a cell and initiating or altering the expression of a gene. They do this by forming a hormone-receptor complex with specific receptors in the cytoplasm before going into the nucleus.
Explanation:Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene. Unlike many hormones that bind to receptors on the cell surface and initiate a signal cascade, such as cAMP activity, steroid hormones can pass through the cell membrane because they are lipophilic. Once inside the cell, they bind to specific receptors in the cytoplasm, forming a hormone-receptor complex. This complex then enters the nucleus and binds to specific genes, initiating or altering their expression, thus influencing the cell's function. It is no the case that these hormones would activate mitochondrial DNA or instigate the hypothalamic release of regulating hormones.

Which refers to the movement of a piece of one chromosome to another nonhomologous chromosome?
Answer:
Translocation
Explanation:
Translocation is a chromosomal abnormality (mutation) in which a chromosome breaks and a portion of it reattaches to a different chromosomal location. It can occur during the formation of sperms and eggs during meiosis.
Translocation is of two main types: 1. Reciprocal location, in which two fragments break off from two different (non-homologous) chromosomes and switch places.
2. Robertsonian translocation, in which an entire chromosome (usually acrocentric) becomes attached to another chromosome (acrocentric) at the centromere to form a metacentric chromosome.
Translocation can either be BALANCED, where no genetic information is missing or additional. Hence, there is an even exchange with no adverse effect on the affected individual or UNBALANCED, where the exchange of chromosomal material is unequal resulting in an extra or missing genes.

In classical conditioning, if the conditioned stimulus is repeatedly presented without the unconditioned stimulus, what will likely occur?
A. stimulus generalizationB. stimulus discriminationC. extinctionD. spontaneous recovery
Answer:
C - Extinction
Explanation:
Extinction is the gradual removal or cessation of a learned behavior. It usually occurs when the behavior is not reinforced.
Classical conditioning can be defined as a process in which a conditioned stimulus becomes paired with an unrelated unconditioned stimulus in order to elicit a conditioned response (behavior) from the subject.
It was a process incepted by Ivan Pavlov.
In classical conditioning, if the conditioned stimulus is repeatedly presented without the unconditioned stimulus, the conditioned response is gradually eroded until it becomes extinct and forgotten.
In classical conditioning, if the conditioned stimulus is repeatedly presented without the unconditioned stimulus, extinction will likely occur.
option c is correct
Explanation:In classical conditioning, if the conditioned stimulus is repeatedly presented without the unconditioned stimulus, extinction will likely occur.
Extinction refers to the gradual weakening and eventual disappearance of the conditioned response when the conditioned stimulus is no longer paired with the unconditioned stimulus. This occurs because the conditioned stimulus no longer predicts the unconditioned stimulus, and the learned association weakens over time.

B. Inserting pieces of DNA, which will result in pest or disease resistance in a crop.
Explanation:
A genetically modified organism (GMO) is an organism in which the genetic material has been changed using techniques of genetic engineering . Genes have been transferred within the same species, across species (creating transgenic organisms) and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered or knocked out.
Creating a genetically modified organism is a long process. The gene that genetic engineers wish to insert into the host organism must be isolated and fused it with other genetic elements. A number of techniques are available for inserting the isolated gene into the host genome. Recent advancements using genome editing techniques like CRISPR-Cas9 that can be used to edit genes within organisms have made the production of GMO's much easier.
