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 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.

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.

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.

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.

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.

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 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 1950s in America were marked by economic growth and cultural development but also by social inequality and political tension, showcasing the era's complex dual nature of prosperity and challenge.

Many people nostalgically reference "the good old days" when considering past historical eras. The 1950s in America are often remembered as a time of economic prosperity, political stability, and burgeoning cultural movements. However, this decade also presented significant social challenges and inequalities. While the post-World War II period saw significant industrial growth and the emergence of the middle class, there were also profound issues of racial segregation, gender inequality, and civil rights struggles. Tensions were heightened due to the Cold War and the fear of nuclear conflict. Women, minorities, and other marginalized groups faced systemic discrimination and fewer opportunities compared to their white, male counterparts. Therefore, the 1950s could be seen as a period of prosperity for some, but one of challenge and strife for others.

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:

I have chosen to use peppered moths and black moths as my example of adaptation.

The species called peppered moths is widespread in Britain and Ireland. This type of moth got its name due to the grey- and black-speckled pattern it has. This structural trait provides the peppered moths with camouflage when resting on tree trunks. A genetic mutation caused some of the moths to have almost black wings. However, moths with this mutation had a smaller population, because these forms were not completely camouflaged when at rest and predators could spot them easily. Thus, the population of the pale peppered moths was higher than that of the black moths.

The nineteenth century brought with it a lot of industrialization. The industrialization created a tremendous amount of soot and air pollution. This led to blackening of urban tree trunks and walls. So, black moths had better camouflage on tree trunks than the peppered moths did. Due to this, there was an increase in the population of black moths, and a decrease in the population of peppered moths as birds more easily preyed upon them because they were easier to see on the dark tree trunks.

Thus, the species of moth that adapted to the changing environmental conditions were survived.

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.
