Answer:
The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis, they do not contain chloroplasts.
Explanation:
Mitochondria are missing from root hair cells.
Root hair cells are specialized plant cells found in the roots of plants. Their primary function is to absorb water and minerals from the soil. To achieve efficient absorption, root hair cells have evolved specific structural adaptations.
Root hair cells are elongated and have a large surface area due to their elongated projections called root hairs. This increased surface area enhances their ability to come into contact with the soil, maximizing water and nutrient absorption. However, due to their focus on absorption and their short lifespan, root hair cells exhibit some structural simplifications, such as the absence of certain organelles.
One notable organelle missing from root hair cells is the mitochondria. Mitochondria are the "powerhouses" of cells, responsible for generating energy in the form of ATP through cellular respiration. Since root hair cells are mainly involved in absorption rather than energy production, they have a reduced need for extensive energy generation. As a result, they don't require as many mitochondria as other cells that are highly metabolically active.

Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.
Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.
Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.
during dna replication the chromosomes contract and the identical halves are called
Answer:
Explanation:
Sister chromatids
During DNA replication the chromosomes contract and the identical halves are called sister chromatids.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
In prokaryotes, DNA replication takes place in the cytoplasm, whereas it happens in the nucleus in eukaryotes.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The two identical copies of the DNA that are produced as a result of this replication are known as "sister chromatids," and they are connected to one another by a section of the chromosome known as the centromere.
Thus, the identical halves of chromosome is sister chromatid.

Carnivores that eat other animals is a situation which shows a biotic factor operating within an ecosystem. Thus, the correct option is D.
What are the biotic factors?
A biotic factor in an ecosystem is a living organism which shapes its surrounding environment. In a freshwater ecosystem, the examples of biotic factors might include aquatic plants, fishes, amphibians, and algae population.
An example of biotic factor should consist of living organisms such as the one "Carnivores that eat other animals". In this example, carnivores are the animals which eat other lower animals for their nutrition. Both the organisms are living hence are the biotic factors of an ecosystem.
Biotic factors of an ecosystem depends upon the abiotic factors for their survival such as water, climate, soil, temperature, and atmosphere, etc.

How does the biodiversity in a food chain compare to the biodiversity of a food web?
Answer:
ExpWhat is Biodiversity?
Biodiversity and food webs
Biodiversity is referred to as the web of life because many microorganisms, plants and animals interact with each other. The relationship among species is an important part of biodiversity.
A food chain is a sequence of who eats whom. The usual order of a food chain is sunlight, plants, herbivore, omnivore and/or carnivore. In one type of farming food chain, green grass and wildflowers use sunlight to grow in a field maintained by a farmer called a pasture. A Billy (boy) or Granny (girl) goat grazes on these delicious plants in the pasture. A goat or any other plant-eating animal is called an herbivore. Animals that rely on the farmer for food and protection are domesticated. In turn, the goat provides milk, meat and wool for the farmer, his family, and others. Humans are omnivores, as they eat plants and animals. The goat also provides fertilizer. Microorganisms decompose the goats’ poop or excrements, which provides fertilizers for the grass and flowers to grow. This is one example of a simple food chain based only on green plants, goats, microorganisms and humans. Millions of food chains exist around the world. Food Chain
Food chains that are related in an ecosystem form a food web. In forest ecosystems, many types of herbivores eat the trees and other plant life. Carnivores, or meat-eating animals such as tigers, lions, and wolves, prey on herbivores. They usually prey on wild animals. Sometimes, if the habitats or homes of carnivores are destroyed, they may also attack goats, sheep or cows for food. For example, in India, farmers may lose their goats to tigers; in Eastern Africa, cows may provide lunch for lions and in Western Canada, wolves sometimes attack the domesticated sheep. Carnivores are an important part of biodiversity because they regulate herbivore populations so that they do not eat their favorite plant species to extinction.lanation:

During the Flowing Water Model demonstration, observe the stream table while water is flowing through it. What do you notice? Record your observations on the lines below. You can use to Word Bank to help you describe what you see.
Answer:The speed of the water flowing downhill will be affected by the degree of incline, and any structures or topographical features in its path. The faster the water flows, the more erosion occurs. Water flowing downhill moves and deposits sand at the bottom of the river. The faster the water flows, the more sand will be deposited at the bottom. A delta at the mouth of a river forms in the same way. Although the formation of the “rivers” in this activity appeared very quickly, in reality rivers can take millions to billions of years to form a path from land to sea.

2. A volcano erupts 40 miles from an owl’s ecosystem. Ash from the eruption blocks sunlight over your ecosystem for several (7-10) months.
a. Explain what happens within the food web in the weeks that follow the eruption.
b. The ash clears and several more months go by. What do you think will happen to your ecosystem?
Answer:
a. Sunlight cannot penetrate through the ash clouds. thus photosynthesize won't occur. so the food chain will begin to collapse from the producer and primary consumer. owls will be out thinking that it's night. they will catch fish resulting in an imbalanced ecosystem. the aquatic population will decrease. then it's the doom days for owls. they will emigrate or will die.
b. the ecosystem will restore. that's how nature works.
The volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new ecosystem will grow after many months.
What is the ecosystem?The ecosystem has both biotic and abiotic components, and there are many food chains and food webs present in the ecosystem, so the volcanic eruption harmed the ecosystem and killed the populations present, but after many months, when the ashes from the volcanic eruption are cleared, a new population will grow and a new community will be seen.
Hence, the volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new community will grow after many months.

of the two cells represented in the figure, which would likely be more efficient at exchanging substances with the surrounding environment?
Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.
Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment.
While on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Answer:
The four types of economic assumptions that can negatively affect the environment are:
1. Natural resources and human resources are infinite
2. It grants an event in the future less value than one in the present; short-term costs and benefits are granted more importance than long-term costs and benefits.
3. All costs and benefits associated with an exchange of goods or services are borne by individuals engaging directly in the transaction (buyer and seller alone).
4. Economic growth is required to keep employment high and maintain social order.
