Skeletal muscle is a muscle tissue used when running a marathon or blinking the eyes and formation of skeletal muscle comes from action and myosin muscle fibers. Smooth muscle are found in the wall of internal organs such as intestine and stomach. Contraction of the smooth muscle enable the organs to performs their function while cardiac muscle is commonly found in the wall of the heart. The contraction of the cardiac muscle enable the heart to beats and pumps blood.

The preservation technique that attempts to remove moisture is dehydration or drying of foods. Many types of food such as meat, fish are preserved for an unlimited period by removing the moisture. This way, the growth of microorganisms in the food is hindered. Dehydration is one of the oldest methods of food preservation. Equipment such as cabinet driers and vacuum driers are used in dehydration.

Desiccation, or drying, is a preservation technique that attempts to remove moisture. It controls microbial growth and prevents spoilage in foods.

Drying, also known as desiccation or dehydration, is a preservation technique that attempts to remove moisture. It can be achieved through methods such as sun drying, freeze-drying, or the addition of salt or sugar to decrease water activity in foods. Desiccation works by controlling microbial growth and preventing spoilage.

The leading hypothesis for the Permian extinction includes massive volcanic activity causing global warming and anoxic conditions, with further speculations on asteroid impacts and climate changes due to glaciation and warming.

The Permian extinction, occurring at the end of the Paleozoic Period, was the largest mass extinction on Earth, with drastic biodiversity losses both in the oceans and on land. Leading hypotheses for this cataclysmic event suggest that extended volcanic activity, which may have led to a runaway global-warming event, played a key role. This volcanic activity spewed enough basaltic lava, particularly in Siberia, to potentially induce severe warming, anoxic oceans, and a subsequent collapse of marine and terrestrial ecosystems.

Additionally, other speculations include asteroid impacts, similar to the one at the end of the Cretaceous period, and rapid climate changes caused by oscillations between glaciation and warming phases. These tumultuous conditions not only obliterated an estimated 96 percent of marine species and 70 percent of terrestrial species but also set the stage for the rise of new life forms in the Mesozoic Era, including the dinosaur's evolutionary lineage.

The carbon cycle is the movement of the carbon through the rock and sediment, the aquatic environment, land environments, and the atmosphere (including living organisms in all that).

Carbon is released from the plant into the atmosphere through the process of respiration in the form of carbon dioxide (CO2). Respiration is the process which is the reverse of photosynthesis. During respiration, the O2, taken in through stomata is used by the cells in the leaves to break down glucose into CO2 and H2O. The other way of releasing carbon from the plant into the atmosphere is by decomposition. Carbon can be stored as biomass in the roots of trees for many decades and then released back into the atmosphere by decomposition. Sometimes, dead plant matter accumulates faster than it is decomposed and the remains stay in underground deposits. When layers of sediment compress this matte,r fossil fuels will be formed and the carbon within those fossil fuels will be released during humane combustion processes.

Carbon is an important constituent of every living organism. The carbon cycle is the movement of carbon through sediment, water, and air to fulfill the requirement. The two ways in which carbon can get from a land plant to the atmosphere are cellular respiration and decomposition.

Carbon cycle is a biogeochemical cycle in which carbon is exchanged among hydrosphere, atmosphere, biosphere, and geosphere of the Earth. The two ways in which carbon can get from a land plant to the atmosphere are:

Therefore, respiration, decomposition, and combustion are some of the process through which carbon is exchanged between different systems of Earth.

The Golgi apparatus is responsible for modifying, packaging, and transporting proteins and lipids within the cell or for secretion outside the cell. It tags proteins with 'shipping addresses' and forms vesicles that carry them to their required destinations, also producing lysosomes for waste digestion.

The Golgi apparatus is an essential organelle found in eukaryotic cells that plays a pivotal role in processing, modifying, and packaging proteins and lipids. It receives proteins from the rough endoplasmic reticulum (ER) and adds 'shipping addresses' or tags to them. The Golgi then encapsulates these proteins into vesicles and dispatches them to their correct destinations within the cell or to the cell membrane for exocytosis. This function of the Golgi apparatus is critical for ensuring that proteins reach their required location to perform their cellular functions. Moreover, the Golgi is involved in the production of lysosomes, which are organelles that contain digestive enzymes to break down waste materials and cellular debris.

The correct answer is by increasing the rate of respiration and heart rate.

The conditions in the body are monitored, to maintain a steady internal environment. This is known as homeostasis. The conditions, which must be monitored, include water content, the temperature of the body, level of carbon dioxide, and blood sugar level.

Homeostasis is the sustenance of the steady internal environment. Automatic control systems all through the body maintain water and temperature at constant levels that are needed for the cells to work adequately.

Answer:

by increasing the respiratory rate

by increasing the heart rate

Explanation:

study island said:

Feedback mechanisms allow the body to maintain homeostasis. For example, the body responds to an increase in skeletal muscle cell activity by increasing the heart rate and respiratory rate.

Increasing the heart rate allows oxygenated blood to be delivered to muscle tissue at a faster rate, while increasing the respiratory rate allows the carbon dioxide produced during cellular respiration to be eliminated more quickly from the body.

Answer:

Homologies and vestigial structures  are two evidences of the evolution of how DNA and comparative anatomy used to show relatedness

Explanation:

Living organisms have characteristics that make them similar to others, which may suggest that at some point in the history of life on Earth, they shared a common ancestor. When we look at the limbs of a crocodile and a rat, for example, we find that, despite their differences in morphology, they are quite similar in anatomy, suggesting that they may be related. In this case, we say that the characteristic is homologous, that is, it has a similar embryonic origin, but it does not always perform the same function.

Trace structures are structures that are atrophied and have no apparent function in an organism. The presence of these organs can be interpreted as evidence of evolution, since the structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.

Evidence for evolution are Fossil Record, Homologous Structures, DNA and Molecular Evidence. DNA and Comparative Anatomy to Show Relatedness as DNA Sequencing, Molecular Clock.

1. Fossil Record: The fossil record provides evidence of how species have changed over time. Fossils of extinct organisms help to establish transitional forms, showing the gradual changes and relatedness between different species.

2. Homologous Structures: Homologous structures are anatomical features in different species that share a common ancestry but may have different functions. These similarities suggest a common evolutionary origin. Comparative anatomy studies these structures and their patterns of variation across species.

3. DNA and Molecular Evidence: DNA and molecular analysis have revolutionized our understanding of evolution. By comparing the DNA sequences of different species, scientists can determine their degree of relatedness. Similarities in DNA sequences provide evidence of common ancestry and evolutionary relationships.

2) DNA and Comparative Anatomy to Show Relatedness:

1. DNA Sequencing: DNA sequencing allows scientists to compare the genetic material of different species. The more similar the DNA sequences are between two species, the more closely related they are thought to be. For example, humans and chimpanzees have a high degree of DNA sequence similarity, indicating a close evolutionary relationship.

2. Molecular Clock: Molecular clock analysis uses DNA mutations to estimate the time when two species diverged from a common ancestor. By comparing the number of genetic differences between species and the mutation rate, scientists can approximate the time of divergence and infer relatedness.

3. Homologous Genes: Just as there are homologous structures, there are also homologous genes. These are genes that are shared between different species because they were inherited from a common ancestor. The study of homologous genes provides strong evidence of shared evolutionary history.

4. Comparative Anatomy: Comparative anatomy examines the similarities and differences in the anatomical structures of different species. Homologous structures, such as the bones in the limbs of vertebrates, reveal common ancestry and relatedness.

5. Embryonic Development: Comparing the embryonic development of different species can reveal similarities in early stages, providing evidence of shared ancestry. For instance, the early embryos of fish, reptiles, birds, and mammals share common features, suggesting a common evolutionary origin.

Answer & explanation:

When we refer to macronutrients, we talk about proteins, carbohydrates and lipids.

In a meal, carbohydrates are usually in greater quantity than proteins and fats, and are primarily used as fuel for metabolic processes.

Carbohydrates have on average 4 kcal per gram (or 17 kJ/g), proteins also have 4 kcal/g, but fats are approximately 9 kcal per gram (or 37 kJ/g).

Thus, fats have a higher energy charge compared to proteins and carbohydrates, although they are not primarily used as cellular fuel.

The answer is B. This is called genetic shift. The pups with advantageous traits are able to survive until the age of reproduction hence able to pass their genes to the next generation. Few and fewer pups with disadvantageous traits will get to reproduce hence the allelic frequencies of the shark population will shift in favour of increased hunting efficiency.

The xylem transports water and provides structural support, the phloem transports sugars, the vascular cambium facilitates secondary growth, and the epidermis protects the plant and minimizes water loss.

Below are the primary functions of the xylem, phloem, vascular cambium, and epidermis:

An edge dislocation of atoms experience tensil, shear and compressive strains. Moreover, tensile strain produce a direct stresses and compressive strain produce in a body when two equal and opposite forces try to compress the body. Meanwhile, shear strain is produce under a shear stress where the body displace transversely from its original position.  

Final answer:

Atoms surrounding an edge dislocation experience strain due to the extra half-plane's distortion of the crystal lattice. This leads to compression above and tension below the slip plane, contributing to various types of strain and understanding plastic deformation by slip.

Explanation:

The atoms surrounding an edge dislocation experience various forms of strain due to the disruption of the normal lattice structure. For a positive edge dislocation, the presence of the extra half-plane causes atoms above the dislocation to be put in compression, while those below the slip plane are in tension. This condition creates a stress field around the dislocation, where the stress is compressive above the slip plane and tensile below it. The strains experienced include the strain caused by the increase or reduction of bond angles, the strain due to eclipsing bonds on adjacent atoms, and the strain caused by the repulsive interactions among atoms attempting to occupy the same space. This phenomenon is fundamental in understanding the process of plastic deformation by slip, where blocks of crystal slide over each other due to dislocation motion under stress, without requiring the simultaneous breaking and reforming of all bonds along a plane.

Answer:

"Those who doubt the effectiveness of this treatment for pain attribute the pain relief to a placebo effect: if a patient believes something will reduce their pain, they will experience some relief."

Explanation:

There is no scientific evidence to prove the healing effect of acumpulture, so some people do not believe it to be a reliable method when relieving pain. The above shows why people who do not believe in the healing power of acupulture believe that those who undergo this treatment really feel a relief from pain. People who do not believe in acupuncture relate this relief to the placebo effect.

Placebo is any substance without pharmacological properties, administered to persons or groups of persons as if it had therapeutic properties. The placebo effect happens when people believe so much that a (ineffective) treatment will work that it actually works.

Answer:

c. warmer than present

Explanation:

The Mesozoic Era (Meso = Middle and Zoic = Life) is marked by the emergence of dinosaurs and encompasses the period from approximately 250 to 65 million years ago. It is divided into three periods, from oldest to most recent: Triassic, Jurassic and Cretaceous. This era was warmer than the present.

Its onset is marked by a large mass extinction of unknown causes and the formation and fragmentation of Pangeia. The enhancement and extinction of dinosaurs is also a striking fact of this era called the “age of dinosaurs” because that was when they developed most. It is also in this Era that the first flowering plants and the first birds appear.

Answer:

✔ Analogous structure

Bird wings and dragonfly wings are both used for flight.

✔ Homologous structure

Clams and snails both have similar muscle structure even though the muscles do different jobs.

✔ Homologous structure

Human and giraffe necks both have 7 vertebrae because we are related.

✔ Homologous structure

The flaps of a Venus flytrap have a similar makeup to oak leaves.

Analogous structures, unlike homologous structures, originated in response to a similar environmental challenge and are similar in function but not structure. Therefore, Bird wings and dragonfly wings are both analogous.

In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.

Examples of similar structures include the wings of flying creatures like bats, birds, and insects, as well as the fins of fish and penguins. Similar structures can be seen in other animals and plants as well, such as those seen in sweet potatoes and potatoes, both of which serve as food storage.
