Answer:
Thanks to its high specific heat, water plays a very important role as a temperature regulator
Explanation:
The specific heat is the amount of heat needed per unit mass to raise the temperature one degree Celsius. The specific heat of the water is 1 calorie / gram. Water is one of the substances with higher specific heat and this is why water plays a very important role as a good temperature regulator.
Water changes its temperature, absorbs or loses a large amount of heat but only changes, either by increasing or decreasing its temperature very little. This property is essential for living beings as it reduces drastic changes in temperature. It also helps that our body does not overheat or over cool since this property helps us maintain thermal balance.
______ polymers can be produced in large quantities at low cost.
Electrical products
Explanation - Polymers of electrical products can be produced in large quantities and low cost. This type of polymer are non-conductive in nature. However, they very high heat resistance property. Polymers for electrical products can mold itself in various shapes and sizes and also can reach very minute areas.
Polymers vary from one item to another. Polymers for commercial packaging is different from polymers of electrical products. Thus, polymers need to be chosen properly according to the use and its effectiveness.
Synthetic polymers, such as plastics and rubbers, are cost-effective to produce and can be engineered for specific uses, from packaging to structural supports. They often have advantages over their natural counterparts and are essential in everyday life, although their non-biodegradable nature calls for effective recycling practices.
Explanation:Synthetic polymers can be produced in large quantities at low cost. The commercial production of synthetic polymers, such as plastics and rubbers, offer economic benefits over natural polymers. Through the process of polymerization, monomers are covalently bonded to form these large, complex molecules, which can then be tailored to have specific properties for diverse applications. High molecular mass polymers are used in a wide variety of consumer goods and materials such as clothing, medical devices, and structural supports experiencing corrosive environments.
Some common synthetic polymers include polyethylene, polyvinyl chloride (PVC), and polystyrene, which are derived from petrochemicals and possess properties that make them versatile and durable. Moreover, adding functional groups to polymers can drastically alter their properties. Recycling of polymers, particularly plastics, is important due to their non-biodegradable nature, which poses environmental challenges. This recycling helps minimize the usage of petrochemical resources and reduces environmental damage.

Help, please! When there is an imbalance in a body system, and the body cannot maintain homeostasis, how might other systems respond?
Answer:
When homeostasis is interrupted, your body may correct or worsen the problem based on certain influences, causing the insulin secreation to be stopped, can alter the blood pH, affect digestive system, and other problems.
Explanation:
Ok, when the is and imbalance in a body system, that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of the organism, causing deseases. Disease and cellular malfunction can be caused in two basic ways: by deficiency (when beneficial pathways are blocked) or toxicity (cells have an excess of a toxin that poisons the cell).
And when homeostasis is interrupted, your body may correct or worsen the problem based on certain influences: it can cause diabetes, where the endocrine system has difficulty to maintain the correct blood glucose levels, you might have a problem producing heat from the nutrients you take in, it causes insulin secretion to be stopped, the plasma pH (blood pH) can be altered by respiratory changes in the partial pressure of carbon dioxide, and other systems may present problems as well.
Other systems may respond by, The digestive system, For example, it helps the body maintain equilibrium by providing nutrients to the body and ensuring factors like blood sugars are maintained. The endocrine system also uses antagonistic hormones such as insulin and glucagon to maintain body homeostasis, And Since body systems are interconnected, then if one system fails to maintain homeostasis, then the other body system will be affected and will also attempt to adjust. An example is an increase in temperatures of the body that will affect digestive system because the enzymes of the body should work optimally at body temperatures.
ez.Gordon added a variety of liquids to a large beaker and allowed them to settle. Which list is ordered from most dense to least dense based on the picture?
Answer:
dish soap, vegetable oil, lamp oil
Explanation:
The substances with higher densities will sink below than those with lower densities.
There are three substances namely oil, honey and water in which the oil with the lowest density floats on the top of the water but the honey with the highest density settles at the bottom.
What is Density?Density is defined as the mass per unit volume of a substance where the symbol used for density is ρ, although the Latin letter D may also be used. Density is defined as mass divided by volume:
[tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]
where, ρ is density,
m is mass, and
V is volume
In the example above, the liquid is honey which is the densest liquid of the group that was analyzed where water is the second densest liquid analyzed which is heavier than oil and ethyl alcohol, and lighter than honey. Oil floats in water, which has a lower density than it does.
Thus, there are three substances namely oil, honey and water in which the oil with the lowest density floats on the top of the water but the honey with the highest density settles at the bottom.

Most deer mouse populations inhabit regions with dark soils. These deer mice have dark brown fur. Populations of deer mice found in the Sand Hills regions of Nebraska, which has tan colored sand instead of dark soil, have tan fur. Which statement best explains why the Sand Hills population of deer mice have tan fur, rather than the dark brown fur found in other populations of deer mice?
Answer:
Tan fur helps the mice protect themselves from predators
Explanation:
The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.
Answer:
Tan fur helps the mice protect themselves from predators

Describe what Bill Nye was trying to demonstrate by removing some of the blocks in his tower of blocks
Bill Nye's demonstration of removing blocks from a tower likely aimed to illustrate physics concepts such as structural integrity, distribution of forces, and stability and balance through the visual and interactive element of the blocks' arrangement.
When Bill Nye was removing some of the blocks in his tower of blocks, he was likely trying to demonstrate principles related to physics, such as the structural integrity of designs, the distribution of forces, or the concept of stability and balance.
For example, by removing blocks from different parts of the tower, he may have been showing how forces are distributed throughout a structure and what happens when that distribution is disrupted. The demonstration would illustrate that certain blocks, much like certain elements within a physical system, play a critical role in maintaining the overall stability and integrity of the structure. When these are removed or altered, it can lead to a collapse or change in the structure's behavior. The lesson behind such an experiment is foundational in understanding concepts like center of gravity, load-bearing capacity, and the importance of proper material and design in architecture and engineering.

Answer:
The correct answer is option B, that is, their predators had been killed off by the Permian extinction.
Explanation:
The avian dinosaurs and the mammals were small creatures, living under the pump of the dinosaurs that reign the world, however, also were ceasing the further enhancement in the development and the size of these species. At the termination of the Cretaceous era, due to the colliding of an asteroid on the Earth, all the dinosaurs got wiped out from the Earth's surface, with the only remaining one of the species of dinosaurs were the small avian species.
Due to the opening of lots of niches, the avian dinosaurs and the mammals briskly began to diversify, evolve, and become much bigger in size. The mammals won the race for supremacy and they became the most prevailing species on the Earth.
Answer:
◉ B. Their predators had been killed off by the Cretaceous-Paleogene extinction.

List four characteristics that are representative of most primates and lead paleoanthropology to conclude that primates share a common ancestry
Answer:
- prehensile hands and feet
- five digits and opposable thumbs
- flexible and limber shoulders and hips
- big and complex brains
Explanation:
The primates are the most intelligent animals collectively, and they include the most intelligent animal on the planet, the human. All of them share some common characteristics that lead the paleoanthropology to conclude that they share a common ancestor. Most of them have prehensile hands and feet, which is a rare among other groups of animals. Almost all of them have five digits on their hands and feet, possessing opposible thumbs as well, enabling them to grab things. The shoulders and hips are also much different than the other animals, being much more flexible and limber. The most important characteristic maybe is their brain, as it is abnormally large and complex when compared with other animals of the same sizes. Their complex brains enable them to perform numerous things that other animals can't even imagine, and eventually that large brain helped in creating the most intelligent animal on the planet, the human.
Primates share several characteristics that lead paleoanthropology to conclude that they have a common ancestry: opposable thumbs, forward-facing eyes, flexible hands and feet, and a large brain relative to body size.
Explanation:Primates share several characteristics that lead paleoanthropology to conclude that they have a common ancestry. Four of these characteristics are:
Opposable thumbs: Most primates have opposable thumbs, which allows them to grasp objects and manipulate their environment.Forward-facing eyes: Primates have eyes that are positioned at the front of their face, providing better depth perception and allowing them to accurately judge distances.Flexible hands and feet: Primates have long fingers and toes with flexible joints, allowing them to grasp and hold onto branches or objects.Large brain relative to body size: Primates have relatively larger brains compared to their body size, which is associated with their higher cognitive abilities.Learn more about Characteristics of primates here:https://brainly.com/question/32632913

Which of the following accuratelydescribes rill erosion?
A. Runoff from heavy rainfall forms narrow, shallow channels. B. A raindrop hits the ground and displaces the surrounding soil. C. Runoff removes soil and loose sediment in thin layers. D. Fast-moving water from heavy rainfall forms deep channels.
Answer:
A
Explanation:
When the surface runoffs are strong enough to cause sediment detachment and if the amount of sediment is within the load limit the runoff can carry, then these conditions are set for rill erosion. The rills are the narrow shallow strips that are formed for in the wake of the runoffs. They are formed from heavy downpours. The runoffs are fast but not as fast and strong as those in gully erosion.
Rill erosion is described as the process where runoff from heavy rainfall forms narrow, shallow channels known as rills across the land. This takes place when the water flows in small streams and erodes the soil, which is a common progression from sheet erosion.
Explanation:The correct answer to the question is A. Runoff from heavy rainfall forms narrow, shallow channels. This describes rill erosion, a common form of water erosion that often develops from sheet erosion. When runoff water accumulates and flows in small streamlets across the land, it creates these channels known as rills. If left unchecked, they can grow larger and potentially join together to form gullies, which are much deeper and more severe channels.
Rill erosion is distinct from rain splash erosion, where the impact of raindrops displaces soil particles, and from sheet erosion, where a thin film of water removes a uniform layer of soil. Unlike gully erosion, which is characterized by the formation of deep channels due to fast-moving water, rill erosion involves the development of smaller, more numerous channels that can gradually expand.
