The assumption that was proven wrong after the invention of sonar is that sound does not travel well in water. Before the invention of sonar, it was believed that sound waves would be absorbed and scattered by the water, making it difficult to use sound for navigation and ranging. However, with the invention of sonar, it was discovered that sound can travel long distances underwater and be used to detect and locate objects, such as ships and submarines.

The distinguishing features of different disaccharides is the arrangement of different monomer units, the configuration of the anomeric hydroxyl group of each residue, the two specific sugar molecules and their stereo configurations. The correct option is (A). Only 1, 2, and 3.

There are a variety of sugars that make up carbohydrates. Glucose, fructose, and galactose are among the most prevalent monosaccharides. They make up a significant portion of the food we consume on a daily basis.

Disaccharides, on the other hand, are carbohydrates composed of two monosaccharides. The monosaccharides' arrangement, anomeric hydroxyl group configuration of each residue.

The two specific sugar molecules and their stereo configurations are all distinguishing features of different disaccharides.

The only feature that is not a distinguishing characteristic of disaccharides is the carbons that are involved in the linkage.  

Therefore, option A is the correct answer. Only 1, 2, and 3 are distinguishing features of different disaccharides.

Ballistochory. So it is called when the seeds are forcefully or explosively spread. The aim is to "throw" the seed from the parent plant as far as possible.

Explanation:

This is what is known by the violent and explosive dispersal of the seeds. The aim is to "throw" the seed from the parent plant as far as possible. (This works because the wind resistance is not high for seeds.)

Answer:

the dispersal of seeds by force

Explanation:

A couple who are both carriers of a recessively inherited gene has two children who both inherited the condition. 3/4 is the probability that their next child will be phenotypically normal. 1/4 has the chance of being diseased.

Inheritance is a mechanism by which the genes of parents pass down to their offspring. A gene "G" is dominant over "g," and Gg is the carrier for the disease but does not show the disease. If two parents are carriers (Gg) then there are two possible gametes from each that are G and g. Total four offsprings will be produced, out of four 3 are phenotypically normal and one is diseased. The punnett square is explained below.

Hence, 3/4 is the chance of producing a phenotypically normal child.

Of all these combinations of gametes, dpy unct with dpy unc will produce a Dpy non-Unc phenotype.

The Dpy non-Unc phenotype is the result of a double recessive mutation, where the worm is homozygous for the dumpy (dpy) mutation and heterozygous for the uncoordinated (unc) mutation. Therefore, to produce the Dpy non-Unc phenotype, we need to cross two worms that are heterozygous for the unc mutation and homozygous recessive for the dpy mutation.

Out of the given combinations, the only one that fulfills these criteria is:

dpy unct with dpy unc

In this cross, the first parent has the genotype dpy/dpy unct/unc, and the second parent has the genotype dpy/dpy unc/unc. Their offspring will have the genotype dpy/dpy unct/unc or dpy/dpy unc/unc, with a 1:1 ratio. Half of the offspring will have the Dpy non-Unc phenotype, and the other half will be Dpy Unc.

Trawling is the fishing technique most likely to damage habitat due to its impact on the seafloor, disturbance of sediment layers, and potential for high bycatch of non-targeted species.

Trawling is the fishing technique most likely to damage habitat due to its destructive nature. The dragging of nets along the ocean floor or midwater can physically harm bottom-dwelling organisms like corals and sponges, while also disturbing sediment layers and increasing turbidity. This disturbance can smother and disrupt the habitats of vulnerable species. Additionally, trawling often results in significant bycatch, capturing unintended species such as endangered or juvenile fish. This bycatch not only depletes populations of non-targeted species but also disrupts the balance of marine ecosystems. These combined factors make trawling more detrimental to habitats compared to other fishing techniques.

blood glucose-

"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."

"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."

body temperature-

" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."

"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."

"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."

"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"

The cells in the brain and spinal cord begin to die without constant perfusion within 4 to 6 minutes. The correct option is a.

Perfusion is the delivery of oxygen and nutrients to the tissues of the body through the bloodstream. If this blood supply is disrupted, the tissues may be deprived of oxygen, which can lead to cell death. The brain is particularly susceptible to damage from hypoxia (low oxygen levels), and if the blood supply is cut off for more than a few minutes, permanent brain damage or death can occur. Brain cells begin to die within 4 to 6 minutes without constant perfusion.

The nervous system depends on a constant supply of glucose and oxygen to function properly. The spinal cord, like the brain, is part of the nervous system and requires adequate blood flow to function correctly. The duration for spinal cord cell death is unknown, but it is reasonable to assume that it is similar to brain cell death because both tissues have high oxygen and glucose requirements.

General Strain Theory, Social Control Theory, and Social Learning Theory are among the leading criminological theories that explain criminal behavior, delinquency, and the reasons why people deviate from the social norm.

General Strain Theory(GST) is a sociological theory that asserts that individuals' strain or stress can lead to criminal behavior. According to GST, three sources of strain; failure, negative stimuli, and separation can contribute to an individual's deviant behavior.

Example: Suppose a person is looking for work but is continually refused because of his age. This may cause the person to feel frustrated and may lead him to engage in criminal behavior.

Social Learning Theory asserts that people learn to be violent or non-violent based on observation and modeling from their environment, and people in their social surroundings. The theory argues that people will engage in criminal behavior if they think the benefits outweigh the negative consequences. the theory also suggests that people are more likely to be violent if they feel their environment encourages it.

Example: A child might be exposed to a parent who uses violence as a means of problem-solving. They may grow up believing that violence is the only way to solve problems and begin engaging in violent behaviors themselves.

Social Control Theory argues that people do not commit crimes or deviant behavior because they fear the negative consequences of doing so and they are less likely to engage in deviant behavior as they have stronger ties to society.

Example: A person may choose not to engage in criminal behavior because they fear the punishment that may come with it.

In conclusion, these three theories attempt to explain criminal behavior and deviant behavior from different perspectives. While General Strain Theory argues that strain or stress leads to deviant behavior, Social Control Theory suggests that people will refrain from criminal activity because of the consequences. Social Learning Theory asserts that people learn from their environment and the people in it and may model or imitate their behavior.

D. Most of the offspring plants will have purple stems, but some will have green stems.

Explanation:

These plants are heterozygous, which means that they have two different alleles of the same gene. One allele, the ANL one, is going to dominate over the other resulting in purple-stemmed plants, which is the color that ANL encodes for.

If we draw a Punnet Square, we can see that the majority of the offsprings will have purple stems, but some of them, the ones that have two recessive alleles, will have green stems.

Viral DNA is inserted into host DNA, and is replicated when the cell divides.

Virus is an infectious agent that cannot replicate on its own, but needs a host to do so. The virus has its own genes (DNA or RNA) surrounded by proteins. The virus then infects the cell and synthesizes its genes to form new viruses.

Viruses have three main parts: their genetic material, a protein coat that will protect this genetic material called a capsid, and a lipid bilayer that will surround the entire virus, which will be its envelope.

Therefore, we can confirm that viral DNA is inserted into host DNA, and is replicated when the cell divides.

Explanation:

The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion.

Answer:

The answer is A. 8 protons, 8 electrons, and 8 neutrons.

Explanation:

This is because Oxygen's atomic number is 8 and its atomic weight is 15.99 units. The atomic number is the number of protons in an atom. This means that there are 8 protons, along with 8 electrons, because the amount of electrons in an atom are equal to the number of protons (not including ions.) Additionally, to discover the amount of neutrons present in the given atom, you must take the atomic weight and subtract the atomic number (aka # of protons present). Once you subtract, you will be left with the number of neutrons. Since the atomic weight is 15.99, you will round it up to 16 and subtract 8, leaving 8 neutrons present. In all, it has 8 protons, 8 neutrons, and 8 electrons.

The cells that make up skeletal muscles are called muscle fibers.

Muscle fibers are specialized cells that make up skeletal muscles, also known as voluntary muscles. These muscle fibers are long, cylindrical cells that are bundled together to form muscle tissue. They are composed of numerous smaller units called myofibrils, which contain the contractile proteins actin and myosin. The arrangement of actin and myosin filaments within the myofibrils gives skeletal muscles their characteristic striated appearance.

Muscle fibers play a vital role in the contraction and movement of skeletal muscles. When a muscle is stimulated by a signal from the nervous system, the muscle fibers contract, generating force and allowing movement to occur. Each muscle fiber is innervated by a motor neuron, which releases neurotransmitters at the neuromuscular junction, triggering muscle fiber contraction.

The structure and function of muscle fibers enable them to generate force, exert control over movement, and support various activities such as walking, running, and lifting objects.
