Yes, it is true. If we do not take care of the plastic on our environment it will harm the environment, consequently harm our future.
Since plastics come from non-biodegradable resources, they cannot be degraded fast by the microorganisms or the sun. This leads to pollution of the environment. This pollution then disturbs vegetation, meaning we cannot plant properly on the soil full of plastic that could take many years to decompose.
Not being able to plant effectively will lead to starvation of wildlife and humans. Also the animals in the sea/ocean are affected by the plasic because they can suffocate from it, it also pollutes the water, disallowing sunlight to get throught deep sea, this will lead to death of fish in sea.
Plastic can also lead to economic losses because money is used to try and get rid of these plastics but more are being made at the same time.
What we can do to avoid all the impacts associated with plastic pollution:
1. Recycle plasic-If we can re-use the plastic after buying them we can actually avoid environmental and water pollution.
By recycling, we can also make some other things from plastics e.g mats for houses.

Describe Patterns Explain in your own words how sharks have changed throughout
their evolutionary history and suggest some reasons why these changes may have
occurred. Think about the shark species you saw in this lab and how they differ and how
they are the same.
Answers
Answer:
HOPE IT HELPS
Explanation:
Sharks have been around for over 400 million years, and throughout their evolutionary history, they have undergone a variety of changes. Some of these changes include the development of more streamlined bodies, the evolution of different teeth shapes and sizes, and the development of more efficient swimming techniques. These changes may have occurred due to a variety of factors, such as changes in the environment, changes in food sources, and competition with other species.
For example, the shark species I saw in this lab, the Great White Shark, has a unique set of adaptations that allow it to be an efficient predator. Its streamlined body and powerful tail allow it to swim quickly and efficiently through the water, while its sharp teeth and keen senses help it to locate and capture prey. Other shark species, such as the Hammerhead Shark, have evolved unique head shapes that help them to detect and capture prey in different ways. These adaptations may have evolved due to differences in food sources or competition with other species. Overall, the evolutionary history of sharks is complex and fascinating, and studying these patterns can help us to better understand how species adapt and evolve over time.
Sharks have undergone significant changes throughout their evolutionary history. Over millions of years, they have adapted and diversified to occupy various ecological niches in the marine environment. These changes can be observed in their anatomical features, reproductive strategies, and feeding habits.
One reason for the changes in sharks' evolutionary history is the need to exploit different food sources and habitats. Sharks have evolved different teeth shapes and jaw structures to suit their preferred prey, ranging from small fish to large marine mammals.
Additionally, changes in body shape and fin structure have enabled them to be efficient swimmers in different environments, such as open ocean or shallow coastal waters.
Another reason for evolutionary changes in sharks is competition and predation pressure. As new species emerge and ecosystems evolve, sharks have had to adapt to survive and thrive in changing conditions. Natural selection favors individuals with advantageous traits, leading to the emergence of new species and the extinction of less adapted ones.
In the lab, different shark species may exhibit variations in size, coloration, fin shape, and behavior. These differences reflect their evolutionary adaptations to specific environments and ecological roles.
Despite these variations, all shark species share common ancestry and basic characteristics such as cartilaginous skeletons, powerful jaws, and an efficient swimming ability, which have been refined over millions of years of evolution.

Additional question: how can the Social-Ecological Model help us with our daily food choices?
Answers
Answer:
factors that influenced daily food choices:
biological determinantseconomical determinantsphysiological determinantsphysical determinantssocial determinantsbehavioral determinantsExplanation:
Social -ecological system is the set of different factors which influence our living styles, our dietary habits, our dress choice etc. on a daily basis. In today's world, everything act is done by people are only based on its popularity or followed by trends. Similarly, our daily food choices are also influenced by the trends and our surroundings in which we live. There is the impact of multiple factors on our daily food choices.
Behavioral factors: behavioral factor is the most important factor which have a huge impact on our daily food choice. An individual health condition, behavior, attitude, work routine majorly influence the food choices. An individual personal preferences, likes and dislikes also influenced his food choices.Biological factors: these factors can influence individually as well as globally. Hunger, nutrient requirements, condition of safe food, health conditions are the major biological factors which play major role, when it comes to choose daily food. These factors can affect the global food preferences, for example in the pandemic of convid-19 food choice were similar of every individual globally. Economic factors: availability of food, cost of food, balancing of needs and demands also impacts our daily food choices. If cost are too high of basic food and the availability is only limited to certain people, it automatically impacts on the food choice of an individual. Social Factor: when we talk about social factors these are the group of different small factors like culture, work environment, school, colleges, religious preferences, friends circles, demographic conditions etc. our daily food choices are mostly based on the social factors because our likes and dislikes, meal patterns, our preference of food (cooked, raw, packages, cooking style etc.) Everything based on the impact of the surroundings. In schools and colleges, students are bound to eat what is available or what their friends prefer to eat. Religious backgrounds always choose as per their rulings. Traditional foods, cultural heritages also an impactful factor for our daily food choices.Physiological factors: mental health condition are also one of the important factor which can not be neglected when we choose our food to eat. A healthy individuals preferences will always be different from a sick person.Social-ecological model can help us with our daily food choices by giving us the knowledge of the factors and its healthy impact on our food choices which can lead us to a healthy life and prosperous environment.

Think about the ecosystem that you live in. Write a response below describing it in complete sentences. Use each of these terms correctly in your description: community . population • ecosystem . individual .biotic abiotic
Answers
Answer:
Within an ecosystem, we can identify different levels of organization, such as individuals, populations, communities, and the overall ecosystem.
Explanation:
An individual refers to a single organism, such as a plant or an animal, living within the ecosystem. For example, a squirrel or a tree in your ecosystem would be considered individuals.
Populations are groups of individuals of the same species that live in the same area and interact with one another. For instance, if there is a group of squirrels living in your ecosystem, we can refer to them as a population of squirrels.
Communities include all the populations of different species living together in a specific area. In your ecosystem, there might be various populations, such as squirrels, birds, insects, and plants, interacting and coexisting with one another. Together, they form a community of different organisms.
The ecosystem encompasses both the living organisms (biotic factors) and the non-living components (abiotic factors) in a given area. The abiotic factors include things like sunlight, temperature, water, soil, and air. They influence the distribution and behavior of the organisms within the ecosystem. For example, the availability of sunlight and the temperature range in your ecosystem will affect the growth of plants and the activities of animals.
An ecosystem consists of the interactions between abiotic and biotic components in a specific area. Abiotic components include non-living factors like water, air, sunlight, temperature, and soil, while biotic components include living organisms like plants, animals, and microbes.
Populations of different species of plants, animals, and microbes make up the biotic components of an ecosystem. Each individual organism, whether a plant, animal, or microbe, interacts with its biotic and abiotic surroundings. The community of different species of organisms in an ecosystem all interact with each other to obtain food, shelter, or other necessary resources.
Some species form mutualistic relationships, while others may be in competition with each other for resources. Therefore, the ecosystem that we live in is the local community of living organisms interacting with the abiotic environment. These interactions between abiotic and biotic components of an ecosystem result in complex and dynamic ecosystems that can change over time.

The Chromosome 18 Inversion
Not all structural rearrangements of chromosomes produce nonviable, impaired, or infertile individuals. In rare instances, such a change can result in the evolution of a new species. In fact, a pericentric inversion in chromosome 18 appears to have contributed to the evolution of humans. This inversion is not present in our closest genetic relatives, the chimpanzees. Humans and chimpanzees differ cytogenetically by pericentric inversions on several chromosomes and by the fusion of two separate chromosomes in chimpanzees that correspond to chromosome two in humans.
The pericentric chromosome 18 inversion is believed to have occurred in early humans following their divergence from a common ancestor with chimpanzees approximately five million years ago. Researchers characterizing this inversion have suggested that approximately 19,000 nucleotide bases were duplicated on 18p, and the duplicated region inverted and reinserted on chromosome 18 of an ancestral human.
A comparison of human and chimpanzee genes in the region of this inversion indicates that two genes—ROCK1 and USP14—that are adjacent on chimpanzee chromosome 17 (which corresponds to human chromosome 18) are more distantly positioned on human chromosome 18. This suggests that one of the inversion breakpoints occurred between these two genes. Interestingly, humans and chimpanzees express USP14 at distinct levels in specific cell types, including cortical cells and fibroblasts. Perhaps the chromosome 18 inversion in an ancestral human repositioned specific genes and reset their expression levels in a useful way. Because both ROCK1 and USP14 encode cellular enzymes, a change in their expression could alter cellular function. It is not known how this inversion contributed to hominid evolution, but it appears to be a significant factor in the divergence of humans from other primates.
According to the passage, which of the following events are believed to have occurred after humans diverged from their common ancestor with chimpanzees?
a. Paracentric inversions occurred at several chromosomes, including human chromosome 18.
b. Two separate chromosomes underwent a pericentric inversion, then fused to form chromosome 2 in humans.
c. 19, 000 nucleotide bases were duplicated, inverted, and reinserted at human chromosome 18.
d. The ROCK1 and USP14 genes were duplicated in early humans, which increased expression of these genes.
Answers
The appropriate response is Early humans duplicated the ROCK1 and USP14 genes, which boosted their expression.
Pericentric inversion refers to the alteration of the normal gene sequence that happens on both sides of the centromere. Each arm of the chromosome has a break point as a result of this inversion. Breakage might happen at two different places.
Human evolution began following chromosomal pericentric inversion. Because of this inversion, humans and chimpanzees no longer share a common ancestor. On the human ancestor's chromosomal number 18, about 19000 nucleotide bases were duplicated, inverted, and then reinserted.
Therefore, alternative is the right response. Early humans duplicated the ROCK1 and USP14 genes, which boosted their expression.
