What factors can affect the blood flow of the cardiovascular system? How can this be prevented and resolved?

Answer:

1

Explanation:

Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs.

the answer is 1 i’m pretty sure

Answer:

copper

rubber

Explanation:

copper conduct electricity and rubber does not

Conductors are materials that permit electrons to flow freely from particle to particle. An object made of conducting material will permit charge to be transferred across the entire surface of the object.
An example of a conductor is - gold, copper, steel, sea water, silver.


An Insulator are any substances that block the flow of electrical or thermal currents.

Example of an insulator - Rubber, glass, oil, diamond & wood.

Answer:

Single use plastic is one of the most prevalent causes of pollution including environmental as well as water pollution. It has devastating impact on oceans, sea animals and hydrophytes. Therefore ban on single use plastic is very important.

Explanation:

we Plastic packaging serves several important functions in our modern lives, which are the primary reasons we rely on it: Protection: protects vulnerable products from damage whilst in transit and from contamination or damage by moisture, humidity, gases, microorganisms, insects and light.

Plastic bags have become a threat to the life of animals living on earth as well as in water. Chemicals released by waste plastic bags enter the soil and make it infertile. Plastic bags are having a negative impact on human health. Plastic bags lead to the drainage problem.

Pls give brainliest!

Single-use plastics are a glaring example of the problems with throwaway culture. Instead of investing in quality goods that will last, we often prioritize convenience over durability and consideration of long-term impacts. Our reliance on these plastics means we are accumulating waste at a staggering rate. We produce 300 million tons of plastic each year worldwide, half of which is for single-use items. That’s nearly equivalent to the weight of the entire human population.

Reducing plastic use is the most effective means of avoiding this waste (and the impacts linked to plastic production and use). Carrying reusable bags and bottles is one great way to avoid single-use plastics in our day-to-day lives; more on preventing plastic waste can be found below.

Recycling more plastic, more frequently, reduces its footprint. Polyethylene terephthalate, one of the most commonly recycled plastics and the material that makes up most water and soda bottles, can be turned into everything from polyester fabric to automotive parts. But a whopping 91 percent of all plastic isn’t recycled at all. Instead it ends up in landfills or in the environment. Single-use plastics in particular—especially small items like straws, bags, and cutlery—are traditionally hard to recycle because they fall into the crevices of recycling machinery and therefore are often not accepted by recycling centers.

Left alone, plastics don’t really break down; they just break up. Over time, sun and heat slowly turn plastics into smaller and smaller pieces until they eventually become what are known as microplastics. These microscopic plastic fragments, no more than 5 millimeters long, are hard to detect—and are just about everywhere. Some microplastics are even small by design, like the microbeads used in facial scrubs or the microfibers in polyester clothing. They end up in the water, eaten by wildlife, and inside our bodies. They’ve even made their way up to the secluded Pyrenees mountain range and down to the bottom of the Mariana Trench. For wildlife, microplastics can be particularly dangerous; when eaten they can easily accumulate inside an animal’s body and cause health issues, like punctured organs or fatal intestinal blockages.

Exposure to microplastics, as well as the chemicals that are added to plastics during processing, harm our health. Many of the chemicals in plastics are known endocrine disruptors,and research has suggested that human exposure could cause health impacts including hormonal imbalances, reproductive problems like infertility, and even cancer. The phthalate DEHP, as just one example from dozens, is often added to plastic goods like shower curtains and garden hoses to make them more flexible—but was also found to be a probable human carcinogen by the U.S. Environmental Protection Agency.
