Answer:
Option (D)
Explanation:
The entropy is usually defined as the measure of the total thermal energy of a system per unit temperature. This amount of energy is used in performing valuable work. In simple words, it can be said that entropy is related to the disorder or degree of randomness of a particular system. This entropy concept gives proper information regarding the direction along which natural change occurs and is frequently observed in many present-day events.
Thus, the correct answer is option (D).

Mixed cranial nerves containing both motor and sensory fibers include all EXCEPT which of the following?
a. facial
b. oculomotor
c. trigeminal
d. olfactory
Answer:
The correct answer will be option-D
Explanation:
Cranial nerves are the twelve type of nerves of the peripheral nervous system which innervate or supply to the structures of the neck and head. Mixed cranial nerves are a type of cranial nerves which contain mixtures of both sensory and motor fibers or nerves.
The main nerves of the mixed cranial nerves are the facial nerve, glossopharyngeal nerves, trigeminal nerves (control mastication muscles) and the oculomotor (control eye movement). The olfactory nerves transmit the sense of smell to the nasal cavity and are not considered the part of the mixed cranial nerves.
Thus, option-D is the correct answer.
The cranial nerves containing both motor and sensory fibers include facial, oculomotor, and trigeminal. However, the olfactory nerve is purely sensory, containing no motor fibers.
Explanation:The cranial nerves that contain both motor and sensory fibers include several, such as the facial, oculomotor, and trigeminal nerves. However, the olfactory nerve is the exception. The olfactory nerve is purely sensory and is responsible for our sense of smell. Therefore, it does not contain any motor fibers, making it the correct answer to the question.

6. Use the results of your observations to explain the roles of muscles, tendons, bones, ligaments, cartilage, and joints in the back-and-forth movement of the lower chicken wing.
Answer:
Explanation:
Muscles are the main form of movement within the wing, extending and contracting the wing, similar to the movement in an arm. Tendons are strands of tough connective tissue that connect the skeletal muscles to bones. Tendons move the wing up and down, allowing for flight and vertical movements. Without tendons, muscles and bones are independent from each other, so by connecting muscles and bones, whenever a muscle contracts or moves, the bone moves as well. Once the bone and muscle have the ability to move together, the body itself can thus be moved in different ways. Muscles also initiate body movements, and, being attached to the bones by the tendons, it controls the movements of the chicken wing by being pushed back and forth. Ligament is the type of connective tissue that connects bones to other bones. The ligaments will allow the bones to move and still keep the bones together in the joint. Cartilages are composed mostly of long, stringy collagen fibers that create bands of tough, fibrous connective tissue. They connect bone to bone at joints and function to reduce friction and protect the ends of the bones when the joint moves. Joints connect the bones together and creates flexibility of the movement being controlled by the muscles and tendons.
Final answer:
The musculoskeletal system includes muscles, tendons, ligaments, bones, cartilage, and joints, which collaborate to enable movement. Muscles contract to move bones, which are connected at joints by tendons and stabilized by ligaments, while cartilage prevents bone friction.
Explanation:
The musculoskeletal system is composed of muscles, tendons, ligaments, bones, cartilage, and joints, all working together to facilitate movement. When a muscle attached to a bone via a tendon is pulled, the resulting movement of the bone at the joint is because the muscle exerts a force, causing a specific action such as flexion or extension, depending on which muscle in the antagonistic pair is contracted. For example, when pulling a muscle in the chicken wing, it flexes at the elbow joint, a process known as flexion. The tendons, which are robust and connective, serve as points of attachment for the muscles to the bones, ensuring efficient transfer of force. Ligaments help stabilize the joints by connecting bone to bone, while cartilage reduces friction between bones at the joints, facilitating smooth motion.
Within a chicken wing, just like in the human body, the tendons are tightly connected to the muscles and bones. When dissecting a wing, one can observe the connection between the tendon and muscle, the muscular activity inducing motion in the wings, and the role of cartilage as a shock absorber and enabler of smooth joint movements. Blood vessels are found between the muscles, providing them with the necessary nutrients.
Ligaments connect bones at the joints, muscles are connected to bones with tendons that allow for movement, and cartilage fills spaces between bones, preventing them from scraping against one another. The skeletal system must work cohesively to sustain movement and provide support and protection to the body.

The sarcomere shortens when the myosin heads of the thick filaments. True or false
Answer:
True
Explanation:
A muscle tissue get shortened only when the sarcomere changes structurally. Myosin form cross bridges with the actin as they head towards the thick filament. Myosin then pulls the thin filaments and shortens the sarcomeres thereby shortening the skeletal muscles. This process continues till the active sites on actin remain exposed and there is ample availability of calcium ion and ATP.
Hence, the given statement is true
Suppose a new form of DNA polymerase III is discovered that does not require a primer to begin synthesis of a new strand. All other properties of the enzyme remain unchanged. If this new enzyme were to be expressed in the same organism that normally expresses DNA polymerase III, what would no longer be necessary to completely replicate all of the cellular DNA?A. DNA polymerase IB. telomeraseC. DNA ligaseD. DNA helicaseE. single strand-binding protein
Answer:
The correct answer will be option-A
Explanation:
DNA replication is the process of making replicas of the DNA from the parent DNA strands mediated by the replication enzymes and the ATP.
DNA polymerase is the enzyme which adds a nucleotide to the 3' end of the growing polypeptide chain thus synthesizing the DNA strand in 5' to 3' direction.DNA polymerase requires an RNA primer sequence and DNA polymerase I to add nucleotides.
Since in the given question, a new DNA polymerase III does not require RNA primer which helps in the synthesis of the Okazaki fragments or the lagging strand, therefore, the cell will also no longer require DNA polymerase I as DNA polymerase I fill the gaps between the Okazaki frangments.
Thus, option-A is the correct answer.

In the experiment of Avery, McLeod, and McCarty, the addition of RNase and protease (but not DNase) to the DNA extracts yielded which of the following outcome? Select one: a. Prevented the conversion of type S bacteria into type R bacteria.b. Allowed the conversion of type S bacteria into type R bacteria.c. Prevented the conversion of type R bacteria into type S bacteria.d. Allowed the conversion of type R bacteria into type S bacteria.
Answer:
The correct answer will be option-D
Explanation:
Avery, McLeod, and McCarty performed the experiment to test the chemical nature of the transforming principle.
The transformation experiment was performed by the Griffith in 1928 which results in the transformation of the avirulent R bacteria strain to virulent S bacteria as S bacteria released a transforming chemical in the solution which transformed the R bacteria to S bacteria.
Since DNase help digest the DNA molecules present in the solution therefore this showed that the transforming principle which turned the R bacteria to S bacteria is DNA.
Thus, option-D is the correct answer.
Avery, McLeod, and McCarty found that adding protease and RNase, but not DNase, to DNA extracts enabled the conversion of R bacteria into S bacteria, concluding that DNA is the transforming principle.
Explanation:In the Avery, McLeod, and McCarty experiment, the scientists aimed to determine the molecule responsible for the transformation of bacteria. Proteins and nucleic acids from the S strain were isolated and introduced to the R strain after being subjected to enzymes that degraded each component. It was found that the addition of protease (which breaks down proteins) and RNase (an enzyme that digests RNA) did not prevent the conversion of R bacteria into S. However, when DNase (which degrades DNA) was added, the transformation did not occur. This led to the conclusion that DNA was the transforming principle.

What would be the expected frequency of dewlap extensions a pushups in males while in the presence of females and a predator vs versus. in the presence of a female alone?
A) Higher frequency for dewlap extension and lower frequency for pushups
B) Lower frequency for both dewlap extension and pushups.
C) Higher frequency for both dewlap extension and pushups
D) Lower frequency of dewlap extension and higher frequency for pushups
Answer:
B
Explanation:
The correct answer is option B
B) Lower frequency for both dewlap extension and push ups.
After a predatory attack, both dewlap extension and pushup decreases whereas during mating with the female both dewlap extension and pushup tend to increase. So, from the above comparison we can say that expected frequency of dewlap extensions a pushups in males while in the presence of females and a predator decreases.
The frequency of dewlap extensions is expected to be lower and pushups higher in the presence of both a female and a predator due to the need to balance courtship and predator avoidance. X-linked recessive traits are more frequently observed in males, a recombination frequency of 0 indicates perfect linkage, and a frequency of 0.5 shows independent assortment.
Explanation:The expected frequency of dewlap extensions and pushups in males while in the presence of females and a predator versus in the presence of a female alone would likely differ based on the context of the situation. In the presence of a predator, it is reasonable to expect that the males might suppress typical courtship behaviors like dewlap extensions to avoid attracting attention, thus resulting in a lower frequency of dewlap extension. However, pushups might be used more frequently in a defensive or territorial display to discourage predators. Therefore, the answer could be D) Lower frequency of dewlap extension and higher frequency for pushups. This context-based behavior allows the individual to balance the needs of reproduction with survival.
Review question specifics:
X-linked recessive traits are observed more frequently in males than in females because males have only one X chromosome, thus any recessive trait present on that X chromosome will be expressed, while females have two X chromosomes and a recessive trait would have to be present on both to be expressed.A recombination frequency of 0 corresponds to perfect linkage and violates the law of independent assortment, indicating that two genes are so close together on a chromosome that they do not get separated by recombination.A recombination frequency of 0.5 corresponds to independent assortment and the absence of linkage, which means that the genes assort independently of each other, as they are on different chromosomes or far apart on the same chromosome.14 peas are generated from parents having the green/yellow pair of genes, so there is a 0.75 probability that an individual pea will have a green pod.
