We need to recycle our waste because Earth is a closed system with respect to
matter, and new matter does not enter the environment. Agree or disagree
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes. So, I am agree with this statement.
Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.

Answer:
The types of waves that emanate from and earthquake are the body waves (P-waves and S-waves), and the surface waves. The surface waves travel along the suface, and are are the slowest, even though they do the most damage in an earthquake. While the P-waves travel the fastest through solids, liquids, and gases. S-waves, however only travel through solids.

What are some benefits of farming for the society/environment?
Answer:
Pasture and cropland occupy around 50 percent of the Earth's habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality. in addition to preserving the earth's natural resources, sustainable agriculture benefits the environment through helping maintain soil quality, reducing erosion, and preserving water. Plants and trees in agricultural systems help to retain and add water to underground aquifers. ... Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time. Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world's working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.
Explanation:
The benefits are:
early agriculture
Morden agriculture's opportunity
Development in farming sustainability

Researchers continued to record the deer population for many years after the coyote reduction. After a few years of growth, the deer population stopped changing much and stayed consistent. What is the term that best describes the continued stability of the population in this ecosystem?
Exponential growth
Carrying capacity
Overshoot
Limiting factor
Carrying capacity is a constant that equals population size at the equilibrium point. The term that best describes the continued stability of the population is option B, carrying capacity.
---------------------------------
Populations that exhibit the logistic growth model depend on density.
Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate.
The population per capita growth rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get equal to each other.
Assuming that population size is N, when
N<K, the population can still grow. N approximates to K, the population´s growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density (for example, competition) or might be density-independent.
Dense-independent factors might be human impact or natural disasters (fires, volcanic eruption, flooding).
In the exposed example we have a small population of deer that could grow and increase in size because of the absence of its predator.
This deer population exhibited continuous growth until it reached a certain point in which it remained stable.
This point is the carrying capacity.
At this point N = K ⇒ the deer population stoped increasing its size because it reached the environmental maximal capacity.

Look at the table for energy used in activities. Ella does 2 hours of dancing a week, plays football for 1 hour a week, and goes swimming for 0.5 hours a week. She has a mass of 55kg. How much extra energy will she need a week in order to do these activities?
Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.
Ella, with a mass of 55 kg, does a series of activities in a week.
Let's calculate how much energy she needs for each activity in total.
DancingEllas does 2 hours of dancing a week, which consumes 18 kJ/kg.h.
2 h × 55 kg × 18 kJ/kg.h = 1980 kJ
FootballElla plays 1 hour of football a week, which consumes 25 kJ/kg.h.
1 h × 55 kg × 25 kJ/kg.h = 1375 kJ
SwimmingElla goes swimming for 0.5 hours a week, which consumes 20 kJ/kg.h.
0.5 h × 55 kg × 20 kJ/kg.h = 550 kJ
Total energy expenditureE = 1980 kJ + 1375 kJ + 550 kJ = 3905 kJ
Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

the enzyme dicer chops dsrna molecules into small pieces of
The enzyme dicer chops dsRNA molecules into small pieces of miRNA and siRNA. The correct option is B.
What is Dicer?
Dicer is an enzyme involved in RNA interference (RNAi), a cellular process that regulates gene expression.
Its primary role is to cleave double-stranded RNA (dsRNA) molecules into smaller fragments.
These fragments are typically around 21-25 nucleotides in length and serve as the building blocks for two types of small RNA molecules: microRNA (miRNA) and small interfering RNA (siRNA).
miRNAs are endogenous small RNA molecules that play a crucial role in post-transcriptional gene regulation. siRNAs are also small RNA molecules but are primarily involved in the defense against viral infections and the silencing of transposable elements.Thus, the correct option is B.

Environmental degradation must be reduced, so by the baseline data of the world's ecosystem must be researched.
What is the world's ecosystem?Ecosystem defines the interaction between living (biotic) components and nonliving (abiotic) components. A living system depends on nonliving factors around them.
Temperature, soil, and light are all components that are necessary for the living system to reproduce and survive. Plants can not do photosynthesis without light and also get minerals and water from the soil.
We need to understand the baseline of the world's ecosystem, so climate-changing conditions can be reduced. Global warming is a critical condition for the ecosystem and can be reduced by research.
Therefore baseline data on the world's ecosystem must be researched to improve environmental conditions.

Answer:
Fungus
Explanation:
Chitin is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi. This would point to it most likely being a fungal agent. Hope this helps!
Chitin is a natural polymer and a nitrogenous carbohydrate. The cell walls of fungus pathogens are formed of the N-acetylglucosamine polymer chitin.
What are pathogens?Pathogens are germs that enter, grow, and cause sickness in their host's body. It simply needs a host body to live.
Pathogens have the ability to circumvent the immune system. It likewise relies on body chemicals to survive. Depending on the kind, these bacteria can move from one host to another in a variety of ways.
What are fungus pathogens?The plant is home to millions of fungus species. Not all of them are pathogenic. Only roughly 300 of them are capable of causing disease. Fungi can be found on the surface of your skin or inside your food. They only cause illness if they overgrow.
Fungi have two protective layers, a membrane, and a cell wall, and they are difficult to destroy. The severity of a fungal infection might vary.
