Explanation:

The statement that best describes how the heart delivers oxygen to the body cells is: "The heart pumps oxygenated blood to the body cells." The heart's main function is to circulate blood throughout the body. The blood that the heart pumps to the body contains oxygen, which is used by the body cells for energy. The heart receives deoxygenated blood from the body, pumps it to the lungs to be oxygenated, and then pumps it back to the body to supply the cells with oxygen. Therefore, the heart's role is to deliver oxygenated blood, not air, to the body cells. The heart does not break down carbon dioxide into carbon and oxygen; this process occurs in the lungs during respiration.

If dinosaurs still roamed the Earth today, my life would be drastically different. To begin with, my daily commute would look a lot different. Instead of cars, trains, and buses, I would likely have to hop on the back of a triceratops or a pterodactyl to get around. I would also have to make sure that I am aware of my surroundings at all times because I could easily become a snack for a hungry T-Rex.

On top of that, my living situation would be quite different. Instead of living in a typical house, I would have to live in a treehouse to avoid being eaten. Furthermore, I would have to be prepared to adapt to my environment as dinosaurs would be a constant presence in my everyday life.

In terms of my diet, it would be quite different as well. Instead of eating burgers and fries, I would have to find ways to hunt dinosaurs in order to have a balanced meal. This would require a lot of skill and would be a huge challenge for me. Additionally, I would have to be careful to only hunt certain species of dinosaurs as some could be very dangerous.

Overall, my life would look very different if dinosaurs still roamed the Earth today. From my transportation to my diet, almost everything in my life would need to be adjusted in order to survive in this new environment.

Eating a more sustainable diet involves consuming food that is produced in a way that has minimal impact on the environment, such as plant-based foods, locally grown produce, and sustainably raised animal products.

Examples of sustainable foods that people can eat include fruits, vegetables, whole grains, legumes, nuts, and sustainably raised animal products such as grass-fed beef, free-range chicken, and wild-caught fish. Locally grown produce can also be more sustainable as it reduces the environmental impact of transportation.

Eating lower on the food chain can benefit both the environment and human health. . Additionally, reducing the consumption of animal products can decrease greenhouse gas emissions and other environmental impacts associated with industrial-scale agriculture.

B.The earth experiences high tides because the gravitational force of the moon attracts the water and solid earth, pulling them closer to the moon

Explanation:

The graph of the total number of species found in an area against the percentage of land under protection would show a positive correlation.

This is because as the percentage of land under protection increases, it is likely that there would be more resources available for species to thrive and more opportunities for habitat restoration and conservation efforts. Additionally, protected areas often provide important ecosystem services that support biodiversity, such as water filtration, carbon sequestration, and soil conservation.

However, it is important to note that the relationship between protected areas and biodiversity is complex and may depend on a variety of factors, such as the size and location of the protected area, the level of protection and management, and the characteristics of the species and ecosystems in question.

Growing crops in space is a complex and challenging process, but scientists are making significant progress in developing a self-sustaining food system for astronauts.

As we explore the possibility of living in space for extended periods of time, one of the crucial factors that need to be addressed is the provision of food for the astronauts. To this end, they are conducting extensive research and developing techniques to grow crops in space.

Growing crops in space is not an easy feat. Unlike on Earth, there is no soil, water, or air circulation in space, and plants need these resources to survive. Moreover, the microgravity environment in space affects plant growth and development, making it challenging to achieve a high yield of crops. Therefore, scientists are using innovative methods to overcome these challenges and create a self-sustaining food system in space.

One approach to growing crops in space is to use hydroponic systems. Hydroponics is a method of growing plants in nutrient-rich water without soil. This method is ideal for space because it requires less water than traditional farming and can be easily controlled.

In addition to using innovative growing techniques, scientists are also experimenting with different types of crops that can grow in space. Some of the crops being studied for space agriculture include leafy greens, radishes, tomatoes, strawberries, and wheat.

These crops are ideal for space because they grow quickly, require less water than other crops, and can be grown in hydroponic or aeroponic systems. By selecting the right crops and growing them in controlled environments, scientists hope to create a sustainable food source for astronauts in space.

The data that supports this idea is wildebeest grazing behaviours assist reduce grass height and prevent fire spread.

Evidence 1: Wildebeest's grazing behaviour lowers grass height and inhibits the spread of fires. As indicated in the article, grazers like wildebeest eat the grass and minimise the fuel available for flames, which prevents fires from spreading and destroying the trees.

Evidence 2: Wildebeest migration patterns can result in a patchy mosaic of grass heights that influence how susceptible grass patches are to burning. According to the article, wildebeest migrate and produce a patchy mosaic of grass heights. This also means that some areas of the savanna are dense with more trees, while others have fewer trees.

As a result of their grazing practises and migration patterns, which support the preservation of a diversified ecosystem, wildebeest are a keystone species in the Serengeti. In the absence of wildebeest, grass height would rise, resulting in more frequent and destructive fires. The ecosystem's diversity would decline and the effect on the trees would be harmful.

Answer:

Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are the macromolecules that contain phosphorus. Phosphorus is an important component of the nucleotides that make up nucleic acids.

In DNA, the phosphate group is located on the 5' carbon of the sugar molecule, which is connected to the nucleotide base via a phosphodiester bond. The phosphate groups of adjacent nucleotides form the backbone of the DNA molecule.

In RNA, the phosphate group is similarly located on the 5' carbon of the sugar molecule, but RNA has a ribose sugar instead of a deoxyribose sugar. RNA also typically contains single-stranded nucleotides, rather than the double-stranded structure of DNA.

Overall, phosphorus plays a critical role in the structure and function of nucleic acids, which are responsible for storing and transmitting genetic information.

Answer:

Explanation:

Charles Darwin's theory of natural selection proposes that in a given population, individuals that possess advantageous traits have a better chance of surviving and reproducing, passing down these beneficial traits to their offspring. The activities in this unit, including Here Today, Peppered Moths, Fork Birds, and Unicorn Island, all provide evidence to support Darwin's theory.

Here Today is a simulation that models the process of natural selection. In this activity, students play the role of predators and prey in a simulated ecosystem. The predators have a higher chance of survival if they are better adapted to the environment, and the prey have a better chance of survival if they possess advantageous traits such as speed or camouflage. This activity demonstrates how advantageous traits are naturally selected over time as they confer a greater chance of survival.

Peppered Moths is a classic example of natural selection in action. The activity explores how changes in the environment, such as the increase in pollution during the Industrial Revolution, can have a significant impact on the survival of a species. The dark-colored moths had an advantage in the polluted environment, as they were better camouflaged against the soot-covered trees, and were therefore less likely to be preyed upon. This led to an increase in the proportion of dark-colored moths in the population, demonstrating how natural selection can result in a shift in the genetic makeup of a population over time.

Fork Birds is another simulation that models natural selection. In this activity, students play the role of birds that must compete for food resources. The birds with longer beaks are better adapted to extract food from deep crevices, while birds with shorter beaks can more efficiently extract food from shallow crevices. This activity demonstrates how natural selection can favor different traits depending on the environmental conditions and the available resources.

Unicorn Island is a fictional simulation that explores the process of natural selection in a fun and engaging way. In this activity, students design their own unicorns with different physical traits and compete against each other in a virtual ecosystem. The unicorns with advantageous traits, such as wings or strong horns, have a better chance of surviving and passing down these traits to their offspring, while unicorns with less advantageous traits are less likely to survive.

In conclusion, the activities in this unit all support Darwin's theory of natural selection by providing examples of how advantageous traits are naturally selected over time, resulting in a shift in the genetic makeup of a population. These activities demonstrate how natural selection operates in a variety of different contexts, from simulated ecosystems to real-world examples of environmental change.

(c) A cowbird removes an egg from a robin's nest and replaces it with one of its own. commensalism

(d) An orchid plant grows on the branch of a tree. The tree remains healthy.​ commensalism

Answer:

A: Mutualism

B: Parasitism

C: Commensalism

D: Commensalism

Explanation:

Mutualism is a relationship between two species of organisms in which both benefit from the association.

Commensalism is a type of relationship between two species of a plant, animal, fungus, etc., in which one lives with, on, or in another without damage to either.

Parasitism is a relation between organisms in which one lives as a parasite on another.

PART A: The yucca plant is necessary for the yucca moth larvae to live because it is their only source of sustenance. The moth pollinates the plant, and in return, the plant provides sustenance for the moth, creating a harmonious partnership.

PART B: Different types of biting lice, fleas, and louse bugs are commensals because they graze safely on avian feathers and the skin flakes shed by animals.

PART C: A female cowbird looks for other species' female birds that are busy depositing eggs in a quiet manner. After locating an appropriate host, the cowbird will break or take one (or more) eggs from the resident bird's nest while it is gone and substitute them with one (or more) of her own.

PART D:

Commensalism is the term used to describe the interaction between plants and orchids. When two species coexist, one of the species benefits while the other is unchanged.
