Which adaptation helps polar bears maintain a constant internal temperature (thermal homeostasis) in cold weather? three layers of fur blubber finding shade underground white skin
Answer: Blubber
Explanation:
it makes sense and I took the test
The adaptation that helps polar bears maintain a constant internal temperature (thermal homeostasis) in cold weather is a thick layer of blubber.
Animals such as whales and polar bears have a thick layer of fat known as blubber. Polar bears can stay warm because of this thick layer of blubber. This layer of blubber insulates their body in order to keep polar bears warm during extremely cold winter conditions.In polar bears, body temperature is maintained at 37° C due to their two layers of fur and a thick layer of blubber that insulate them.In conclusion, the adaptation that helps polar bears maintain a constant internal temperature (thermal homeostasis) in cold weather is a thick layer of blubber.

Explanation:
What are 3 potential solutions to stop heat waves? (what solutions are cities looking at) IN DETAIL. Please I need ur help
Answer:
Explanation:
Increase shade around your home
Planting trees and other vegetation lowers surface and air temperatures by providing shade and cooling through evapotranspiration. Trees and vegetation that directly shade your home can decrease the need for air conditioning, making your home more comfortable and reducing your energy bill. Trees also protect your family’s health by improving air quality, by providing cooling shade for outdoor activities, and reducing exposure to harmful UV radiation.
Install green roofs
A green roof, or rooftop garden, is a vegetative layer grown on a rooftop. Green roofs provide shade and remove heat from the air through evapotranspiration, reducing temperatures of the roof surface and the surrounding air. Green roofs absorb heat and act as insulators for your home, reducing energy needed to provide cooling and heating (which decreases your energy bill), improving indoor comfort, and lowering heat stress associated with heat waves.
Install cool roofs
Cool (or reflective) roofs help to reflect sunlight and heat away from your home, reducing roof temperatures. This allows for your home to stay cooler, reducing the amount of air conditioning needed during hot days. According to a study conducted in California1,cool roofs can provide annual energy savings of almost 50 cents per square foot. Such energy savings can also result in better air quality in your community and fewer greenhouse gases emitted to the atmosphere.
Use energy-efficient appliances and equipment
Using efficient appliances and equipment in your home can help to lighten the load on the electric grid during heat waves, thus ensuring a more reliable supply of electricity to your community. When purchasing products, look for EPA’s ENERGY STAR label to help you make the most energy-efficient decision. You can find the ENERGY STAR label on more than 60 kinds of products, including appliances, lighting, heating and cooling equipment, electronics, and office equipment. Replacing your old appliances and equipment with ENERGY STAR-qualified products can also help save you money.
Check on your friends, family, and neighbors
Heat waves can be dangerous for people’s health and safety, particularly for the elderly, young, sick, and poor. Checking on your friends, family, and neighbors during hot days and making sure they have access to air conditioning or cooling centers will help to prevent heat-related illnesses and death.

Explanation:
Im pretty sure my answer is correct.
Apuk’we, the common cattail is a versatile native edible plant for the Ojibwe people of Minnesota. They are important to the ecosystem for many reasons. They help stabilize marshy borders of lakes and ponds, help protect shorelines from wave erosion, providing spawning areas for northern pike, provide cover and nesting sites for waterfowl and marsh birds such as the red-winged blackbird, are a food source for muskrats and beavers, and humans, too. However, where native cattails once stood, now there is a vast lawn of nonnative narrow-leaved cattails or their hybrid offspring. These new cattails are taking over wetlands once populated by the native cattails, decreasing the biodiversity in these areas.
What kind of ecological relationship exists between the native and nonnative species of cattails in the Minnesota wetlands?
A) commensalism
B) competition
C) mutualism
D) predation
Answer:
B) Competition
Explanation:
The native and non-native cattails are competing for the area.
Answer:
Predation
Explanation:
The way the question is worded, gives me the effect that the nonnative species of cattails predated the native species and ultimately, lowered their numbers.
I was torn between competition or predation, but it cannot be competition due to the effect it's having on the native species. In competition, there's obvious tension between the two, though in this scenario, the species is just lowered completely. There's a chance it could be competition though, I'm not really understanding the wording of the scenario given; that's just me though.
So, ultimately, it's predation.

Answer:
Prohibit the cutting of down of trees.
Plastics and non-biodegradeable to be recycled and not dumped to water bodies.
Introduction of carbon-tax.
Explanation:
Carbonmonoxide is the major cause of greenhouse gases which is a huge pollutant in the atmosphere. This gas when released into the atmosphere from human activities like cooking; factory activities and the rest oxidizes in the atmosphere to form Carbondioxide which takes about 40years to be completely depleted in the atmosphere; however- this tall trees would help to absorb this Carbondioxide which is used for photosynthesis.
2. Dumping of waste that cannot be decomposed goes into water bodies which pollute the water bodies and reduce marine life.
3. Introduction of carbon-tax to reduce unguarded discharge of carbonmonoxide into the atmosphere from economic or household activities.

Explanation:
Arteries must be thicker than veins to be able to withstand the high pressure the heart exerts as it pumps blood into them. As blood travels
through the body, this pressure decreases. Blood pressure is the lowest in the veins as the blood heads back to the heart.
Based on blood pressure differences between arteries and veins, which of these must be true?
OA Blood flow tends to be faster in arteries than in veins.
O B. Blood pH tends to be higher in veins than in arteries.
OC. Blood flow tends to be faster in veins than in arteries.
OD. Blood viscosity tends to be higher in arteries than in veins.
Answer:
A Blood flow tends to be faster in arteries than in veins.
Explanation:
Veins and arteries are both blood vessels i.e. conducts blood in the circulatory system. As rightly said in the question, the walls of the arteries are thicker and stronger than that of veins in order to be able to withstand the high pressure of blood that flows into it from the heart. The veins, on the other hand, has a lower blood pressure since blood flows back into the heart.
Based on this fact that blood flows forcefully i.e. high pressure, out of the heart into the arteries, blood will flow faster in the arteries i.e. with high speed which is responsible for the high pressure that the blood exerts on its wall.
Answer:
Option A
Explanation:
Blood flow which is characterized by its velocity tends to be faster in arteries than in veins and inversely varies as its cross-sectional area. Blood flow is faster in the arteries as it carries blood away from the heart at high blood pressure rate and this continues if the cardiac output is continually compensated for.
