How do mammals conserve their heat?
Answer:
with hair or fur
Explanation:
All mammals are endothermic. They conserve body heat through their hair and fur.
What are endothermic animals?Those animals that can regulate their body temperature are known as endothermic or warm-blooded animals. They can survive even when the temperature fluctuates during seasonal changes. They can live in various climates.
When the body temperature of a mammal increases too high then this condition is called hyperthermia, and body temperature reduces too low, then it is called hypothermia.
Hypothalamus is a part of the brain that maintains the temperature of the body, it is responsible for heat production and heat loss. In mammals, heat generates during cellular metabolism. This process is called thermoregulation.
Hence, this is how mammals conserve their body heat.

One theory of early life on Earth states that the first life forms did not use oxygen for respiration and were unable to make their own food. Based on this theory, which types of organisms were most likely present?
aerobic, autotrophic bacteria
aerobic, heterotrophic bacteria
anaerobic, autotrophic bacteria
anaerobic, heterotrophic bacteria
Answer:
Early organisms would have to be anaerobic, as air was likely non existent. This rules out the first two options.
Autotrophic can be called producers, and heterotrophic can be called consumers.
The question states that "did not use oxygen for respiration and were unable to make their own food"
Only one option satisfies the question:
anaerobic, heterotrophic bacteria
Answer:
Anaerobic, heterotrophic bacteria

C. as you move up the structure the group becomes more specific
D. as you move down the structure, there are fewer organisms in each group
Answer:
D. as you move down the structure, there are fewer organisms in each group.
Explanation:
When we move down from kingdom to species, the number of organisms decreases because more closely related organisms are placed down the group. There are fewer kingdoms that have a large number of organisms in it and has less similarities among them and when we move down, the number of organism decreases in number and at the end there are few organisms are present in it which is more closely related to each other.
