Are humans really cold blooded? Please, thank you

Humans can't be cold-blooded. Cold-blooded animals are animals whose body temperature is not constant, and the body temperature of humans is constant at around 37. In fact, almost all birds and mammals are warm-blooded, and the body temperature is constant.

Humans are also a member of the mammals. Moreover, the ancestor of human beings, Australopithecus, is also a warm-blooded animal. Cold-blooded use on people is just a curse word, which means that people have no emotions and will not have biological significance.

1.Because cold-blooded animals do not need to use their own energy to warm or cool down, cold-blooded animals of the same weight only need 1 10-1 3 energy to survive compared to warm-blooded animals, and therefore only need relatively little food. Because they are more likely to accumulate enough energy, cold-blooded animals also have a shorter reproductive period.

2.Most of the time, hot-blooded animals can drive cold-blooded animals to extinction, because hot-blooded animals have more time to find food. Although cold-blooded animals are more efficient at converting food into growth than hot-blooded animals, hot-blooded animals can grow continuously (cold-blooded animals will stop growing when food is extremely scarce or the temperature is very low) until they reach adult size.

3.A person's body temperature is constant. According to Darwin.

The doctrine is that because of natural selection, there may have been cold-blooded human beings before, but because they could not adapt to the environment and were eliminated, furthermore, the constant movement of our heart is an important reason for blood circulation to all parts of the body, which is an important reason for constant temperatureWish.

We often say cold-blooded in our lives, which refers to a person's ruthlessness, and we often say that people are hot-blooded youth, which seems to be very contradictory, in fact, this is our conventional saying, but specifically if you want to say that people are physiologically hot-blooded or cold-blooded, I think that the scientific listing regulations are constant temperature, and our distinction between hot and cold is only for people's psychological and spiritual distinctions!

No, at most some people are ruthless enough and their blood is cold enough, and most people are hot-blooded.

No, humans are primates, warm-blooded animals.

No, humans are primates, homeotherms.

Cold-blooded animals are: turtles, snakes, lizards, frogs, salamanders, sharks, crocodiles, bats, octopuses, starfish, etc.

Cold-blooded animals are commonly known as ectotherms. Animals whose body temperature changes with outside temperature. This property is called ectothermic. Animals other than birds and mammals are cold-blooded.

The body temperature of small aquatic animals is roughly equal to the outside temperature, but the body temperature of large animals, especially terrestrial animals, is quite different from the outside temperature.

Frogs** moist animals, because of the evaporation of the body surface, the body temperature at rest is slightly lower than the air temperature, and changes with humidity and air current. Almost all animals other than sedentary living have so-called behavioral thermoregulation, which is called temperature selection, in which they move to a place with a suitable temperature.

Insects, or reptiles, can change direction toward sunlight as their body temperature changes, allowing them to regulate their body temperature to some extent (exothermia).

In addition, some animals can provide a fairly high body temperature (internal temperature) through the heat generated by muscle activity. Lively swimming fish, or flying insects, their body temperature can be 10-20 times higher than the outside temperature. When it is cold, butterflies and moths flap their wings before flying in preparation for raising their body temperature.

Social insects such as bees use muscle movement and water evaporation to regulate the temperature of the hive.

The metabolic-body temperature curve of cold-blooded animals is like the reaction rate-temperature curve of enzymes, i.e., the metabolic rate increases with temperature. The maximum value is reached at the optimum temperature, but drops sharply at the high temperature. Various physiological processes and reaction speeds exhibit the same temperature dependence.

Cold-blooded animals are much more tolerant to changes in body temperature than homeothermic animals, but when the body temperature drops acutely, they cannot carry out life activities and enter hibernation.

Many people love pets, not only because of their cute appearance, but more importantly, because of their sense of companionship. Most people will choose cats and dogs with strong interaction, and only a few people will choose to raise some non-mammals, such as fish, insects, reptiles, etc.

Fish, amphibians, reptiles are all cold-blooded animals, cold-blooded animals are ordinary people, the common name for them, and their scientific name is ectothermic, their body temperature will change with the change of temperature to better adapt to the environment.

Like turtles, snakes, lizards, sharks, crocodiles, bats, octopuses, starfish, these animals are cold-blooded animals, and the reason why they are called cold-blooded animals is because these animals can change their body temperature with the outside temperature.

Cold-blooded animals are also called ectotherms, when the external environmental temperature rises, the metabolic rate in the animal increases, on the contrary, when the outside temperature decreases, the metabolic rate in the animal slows down, such as snakes, lizards, and turtles burrow into burrows or hibernate when the temperature is low.

Cold-blooded animals are actually ectotherms whose body temperature changes with the change of temperature. Common cold-blooded animals are snakes, crickets, and most of the rest are cold-blooded except for mammals and birds.

Cold-blooded animals include snakes, crocodiles, turtles, baby fish, etc. These animals are called cold-blooded because they do not have a thermostat system in their bodies, or because they regulate their body temperature through their actions.

Cold-blooded animals are animals that do not have an internal thermostat system. Generally uneven body temperature, or actions to regulate body temperature, such as lizards, chameleons, crocodiles, snakes, ......

Ectotherms (commonly known as cold-blooded animals) are animals that are other than mammals and birds, and most of the animals on the earth are ectotherms. Because there is no mechanism for regulating body temperature in the animal's body, the ectothermic animal can only rely on its own behavior to regulate the emission of body heat or absorb heat from the external environment to increase its own body temperature.

When the temperature of the external environment rises, the metabolic rate of the animal increases, and the body temperature gradually rises, and they passively leave the unfavorable environment; When the temperature of the external environment decreases, the metabolic rate of the animal also decreases, and the body temperature gradually decreases.

When we often talk about cold-blooded animals, we refer to people who lack feelings or have no feelings, and from such a point of view, the answer is naturally no. The second refers to low-temperature animals, such as snakes. In nature, the higher the rank of the animal, the closer it is to a homeothermic animal, and man, as a relatively advanced mammal, belongs to the homeothermic animal.

So the answer is also no. That is, man is cold-blooded and is wrong.

Cold-blooded animals are animals that cannot maintain a constant body temperature (cannot maintain a constant body temperature) in their own body, and must maintain their body temperature by irradiating the sun. So cold-blooded animals generally do not move at night. It is dominated by vertebrates, reptiles and amphibians.

Humans are not cold-blooded animals (they cannot regulate their own body temperature) Cold-blooded animals are reptiles and amphibians.

No, humans are homeotherms.

Because he is calm, he is cold-blooded, because he is bold, so hot-blooded, it all depends on a person's personality, and being cold-blooded is not necessarily a bad thing, because he is very calm and calm, but his EQ has decreased a lot, and he is showing it in a cold form to people, and the landlord must have been splashed with cold-blooded cold water

Cold-blooded animals are a common name for ectotherms. This animal is referred to hereafter as "ectothermic". Animals whose body temperature changes with the outside temperature are called ectotherms.

With the exception of birds and mammals, all animals are ectotherms, but they are not unable to fully control their body temperature. Ectotherms are able to change their body temperature by seeking a cool or warm environment, and they lack the physiology to maintain a certain body temperature, such as a well-established heart.

Ectothermic animals are animals that do not have an internal temperature control system, and they cannot maintain a constant temperature (cannot maintain a constant body temperature) in their own body, and they must maintain their body temperature by irradiating the sun, or regulate their body temperature by acting. So ectotherms are generally not nocturnal. Larger ectotherms, such as snakes and crocodiles, need to bask in the sun in the morning to raise their body temperature so that they can move, so they are almost always active during the day and rest at night.

Although the number of ectotherms in the same environment can be dozens of times that of homeotherms, the adaptability of ectotherms to the environment is weaker than that of homeotherms. Homeothermic animals, for example, can overcome the adverse factors of the environment and have a longer time and a wide range of space to obtain food.

Ectothermic animals are animals that do not have an internal temperature control system, and their body temperature cannot be kept constant, so they need to irradiate the sun.

to maintain body temperature, or to regulate body temperature by action. So ectotherms are generally not nocturnal. Larger cold-blooded animals such as snakes and crocodiles need to bask in the sun in the morning to raise their body temperature so that they can move, so they are almost always active during the day and rest at night.

In general, homeothermic animals are able to control and adjust their body temperature by controlling the internal heat generated by their bodies. When the environment changes, homeothermic animals can maintain their internal body temperature constantly. Humans are also a type of homeothermic animal, and the constant temperature of humans is normal at 37 degrees Celsius.

In order to maintain the constancy of body temperature, homeothermic animals have evolved a variety of functional tissues suitable for their living environment, such as feathers, fur and sweat glands, through natural selection and selection nature. Both hair and feathers can keep you warm during the cold winter months; Also, in the hot summer, animals.

The sweat glands can secrete sweat, which can make the heat in the animal's body be dissipated in time to maintain the normal body temperature of the animal. Because homeothermic animals can maintain a constant body temperature all the time, they have a wider range of activities, and will not be affected by the normal environment of nature and climate change, and can live more freely in different environments.

This is because this animal needs to maintain its body temperature by basking in the sun.

Because their body temperature is not maintained at a constant temperature all the time.

It is perceived as cruel and devoid of any feelings.

Because the temperature of their blood changes with the environment.

Because they can't control their own temperature.

Because it is perceived as cruel.

Because they're not homeotherms.

Cold-blooded animals are for us humans and other homeothermic animals, homeothermic animals can speed up or slow down the metabolism in the body according to the problems outside the body to maintain the constancy of the question, such as sweating when it is hot, goosebumps when it is cold, and so on.

However, some animals do not have this kind of regulation skills, and their body temperature will change with the changes in the surrounding environment, just like a cup of hot water in the refrigerator will slowly become cold, cold blood does not mean that his blood itself is cold, but because he does not have the physiological function to regulate the temperature in the body. For example, snakes and other reptiles and amphibians.

They don't have any feelings, they don't know how to be grateful.

That's because they're ectotherms.
