The topic  is "compare aerobic and anaerobic physical exercise" :Continuous movement during aerobic exercise is powered by oxygen from your breath. Anaerobic exercise comprises quick bursts of intense activity that are powered by muscle energy.

Aerobic and anaerobic exercises are two types of physical activities that provide different benefits and require different energy systems to fuel them. Aerobic exercise is a low-to-moderate intensity activity that can be sustained for a prolonged period, such as jogging, cycling, or swimming.

Anaerobic exercise is a form of physical exercise that is characterized by short, high-intensity bursts of activity that rely on energy sources in the absence of oxygen. This type of exercise typically involves activities that are intense enough to cause a buildup of lactic acid in the muscles.

Answer:

Adaptations

Explanation:

Can be inherited through offspring from parents or an organism changes to adapt to an environment and stay alive in order to survive

The survival of the fittest is the quote given by Charles Darwin. The scientist explained the theory of evolution and how organisms transmit adaptable changes from one generation to another.

The correct answer is:

Option C. Adaptations

Adaptations are defined as the changes in the trait of an organism, which helps them to survive and reproduce more in the given surrounding. The evolution of organisms is influenced by environmental factors.

The adaptable changes are heritable, which help the respective generations of the organisms to survive and live longer. Example of adaptations is long necks of giraffe beaks of finches, and stream-lined body of aquatic animals.

Thus, the adaptations help the organism to live, survive, and reproduce more.

Answer: Three key parts of the recipe for evolution are variation, selection, and inheritance.

Explanation:

VARIATION:- The first part of the recipe is variation. Variation refers to the differences that exist between individuals within a SPECIES. These variations can be caused byGENETIC MUTATION, environmental factors, or a combination of both. Some variations may be advantageous and provide a better chance of survival, while others may be disadvantageous and decrease the chances of survival.

Selection: The second part of the recipe is selection. Selection refers to the process by which individuals with advantageous variations are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This is known as natural selection, and it is the driving force behind evolution.

Inheritance: The third part of the recipe is inheritance. Inheritance refers to the passing down of genetic traits from one generation to the next. Offspring inherit genetic traits from their parents, including any advantageous variations that their parents may have had.

The organisms get some energy, while the remaining energy is discharged as thermal energy into the ecosystem. In an ecosystem, as we proceed up the trophic levels, we notice that the amount of energy keeps decreasing.

This phenomenon happens as a result of an ecosystem's inefficient energy transfer from one trophic level to another. The majority of the energy is discharged into the atmosphere as heat. It is known that around 10% of the energy in an ecosystem moves from one trophic level to another.

Thus, we can state that while the organisms receive some energy, the remainder enters the ecosystem as thermal energy. The amount of energy in an ecosystem decreases as we move up the trophic levels, as can be seen.

I don't really understand your statement

Although it is believed that the Salk polio vaccine (IPV) is far less harmful than the Sabin polio vaccine (OPV). It's true.

There are two different polio vaccines available: the Salk vaccine, which uses a killed virus, and the Sabin vaccine, which uses a live but attenuated (or weakened) virus. Many nations switched to the safer IPV vaccine as a result of the possibility of OPV-associated paralytic polio. While IPV is less effective at preventing transmission than OPV5 because it triggers a considerably lower mucosal immune response, it is still quite protective against illness.

By using IPV-OPV instead of OPV, paralysis cases associated with OPV may be reduced by 54% to 100% without impacting vaccination rates, the frequency of significant adverse events, or humoral immunity. However, for some strains of polio, it might worsen mucosal immunity.

Community 1 has greater richness while community 2 has greater evenness.

Community number 1 has many trees of different species that are spread in the same region. In ecology, it is customary to call this situation richness, showing that the area is rich in species.

Community number 2 has different species in smaller numbers, as most of the trees present in the area belong to the same species. This means that this area has little diversity, but a lot of evenness.

Answer:

In biology, saltation (from Latin saltus 'leap, jump') is a sudden and large mutational change from one generation to the next, potentially causing single-step speciation. This was historically offered as an alternative to Darwinism. Some forms of mutationism were effectively saltationist, implying large discontinuous jumps.

Speciation, such as by polyploidy in plants, can sometimes be achieved in a single and in evolutionary terms sudden step. Evidence exists for various forms of saltation in a variety of organisms.

History

Further information: Alternatives to evolution by natural selection

Prior to Charles Darwin most evolutionary scientists had been saltationists.[1] Jean-Baptiste Lamarck was a gradualist but similar to other scientists of the period had written that saltational evolution was possible. Étienne Geoffroy Saint-Hilaire endorsed a theory of saltational evolution that "monstrosities could become the founding fathers (or mothers) of new species by instantaneous transition from one form to the next."[2] Geoffroy wrote that environmental pressures could produce sudden transformations to establish new species instantaneously.[3] In 1864 Albert von Kölliker revived Geoffroy's theory that evolution proceeds by large steps, under the name of heterogenesis.[4]

With the publication of On the Origin of Species in 1859 Charles Darwin wrote that most evolutionary changes proceeded gradually but he did not deny the existence of jumps.

From 1860 to 1880 saltation had a minority interest but by 1890 had become a major interest to scientists.[5] In their paper on evolutionary theories in the 20th century Levit et al wrote:

The advocates of saltationism deny the Darwinian idea of slowly and gradually growing divergence of character as the only source of evolutionary progress. They would not necessarily completely deny gradual variation, but claim that cardinally new ‘body plans’ come into being as a result of saltations (sudden, discontinuous and crucial changes, for example, the series of macromutations). The latter are responsible for the sudden appearance of new higher taxa including classes and orders, while small variation is supposed to be responsible for the fine adaptations below the species level.[6]

Explanation:

Rosalind Franklin produced critical x-ray crystallography data for the modern model of DNA.

The DNA double helix was first conceptualized by British physicist Francis Crick and American biologist James Watson in the early 1950s. In this scientific "marathon," they were the first to reach the finish line, while others like Linus Pauling (who discovered protein secondary structure) were also looking for the right model.

Watson and Crick gathered and analyzed previously obtained data, combining it in novel and illuminating ways, rather than doing brand-new tests in the lab. Rosalind Franklin, a scientist working in physicist Maurice Wilkins' lab, provided them with some of the most important hints about the structure of DNA. Franklin was a master of X-ray crystallography, a potent method for figuring out the structure of molecules. When a molecule, like DNA, is subjected to X-rays in its crystallized form, part of the rays are refracted by the crystal's atoms, creating a diffraction pattern that reveals information about the structure of the molecule.

Answer:

The correct answer is - there is a 12-Carbon ring in ATP synthase of species A whereas species B contains a 10-carbon ring.

Explanation:

ATP Synthase is a protein complex that catalyzes the transfer of the protons down the gradient build by the action of the electron system in the mitochondria and makes ATP from ADP molecules.

The higher number of carbon in ATP synthase will require more protons to rotate to produce 3 ATP in this process so, if species A has more carbon present it will take more protons and able to produce only 83% of ATP compared to species B.

Explanation:

The first organism is a Filter Feeder, which filters water to consume phytoplankton (microalgae).

The second organism is a Scraper/Grazer, which consumes leaves and algae and fungi on the leaf surface.

The third organism is a Shredder, which consumes algae on rocks.

The fourth organism is an Invertebrate Predator, which preys on small invertebrates.
