Explanation:
Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body's oxygen level might drop include: During intense exercise.
There is a system of naming species in biology called binomial nomenclature. It is based on the use of two Latinized names for the identification and classification of each species and was created by the Swedish botanist Carl Linnaeus in the 18th century.
In this system each species is given a separate two-part scientific name, consisting of a genus name (the first part) and a species epithet (the second part). The species epithet is written in lower case, but the genus name begins with a capital letter. When written by hand, names are either underlined or printed in italics. Additionally, whenever a scientific name is used in prose, the full name is often italicized.

black fur
Himalayan Rabbit
A scientist shaved an area of white fur on the back of a Himalayan rabbit and placed an ice
pack over the shaved area. The shaved area grew black fur.
Which of these best explains why the hair that grew back where the ice pack was placed was
black and not white?
F The genes for black hair were activated by specific temperatures.
G The white hair mutated to black hair as the rabbit's body temperature decreased.
H The coat color changed from white to black with the age of the rabbit.
3 White hair only grows during certain times of the year.
Rabbits regulate their body temperature by using their ears. A fever or a dip in body temperature could be indicated by extremely chilly or hot ears. Thus, option F is correct.
In general, rabbits thrive in cooler climates. In the fall, rabbits stop shedding their fur and develop a thick coat of fur that keeps them warm in the winter. Low temperatures of 32 degrees don't really bother them.
Strong back legs offer rabbits the speed they need to run away from predators. Their feet have fur on the bottoms for warmth and strong claws for traction.
The white hair only grows in cold temperatures. Just because they put an ice pack on the rabbit does not mean that it's cold.
Therefore, The genes for black hair were activated by specific temperatures

Answer:
F. The genes for black hair were activated by specific temperatures
Explanation:
The white hair only grows in cold temperatures. Just because they put an ice pack on the rabbit does not mean that its cold.
b. stratosphere
c. mesosphere
d. thermosphere
Auroras occur in the "thermosphere".
The thermosphere lies between the exosphere and the mesosphere.It is a district of expanding temperature in Earth's climate that is situated over the mesosphere.
The thermosphere significantly helps in ensuring the earth and making space investigation and present day types of correspondence conceivable. It additionally supports and ensures life on the planet. It reuses water, retains the sun's energy, and makes a moderate temperature.
The aurora (Northern Lights and Southern Lights) generally present in the thermosphere. It is a natural electrical marvel described by the presence of streamers of rosy or greenish light in the sky, particularly close to the northern or southern attractive shaft. The impact is caused by the communication of charged particles from the sun with iotas in the upper atmosphere.
Auroras occur in the thermosphere. Therefore, the correct option is D.
The Northern Lights, or aurora borealis, and the Southern Lights, or Aurora Australis, are natural light displays that occur in Earth's upper atmosphere. The thermosphere, the uppermost part of Earth's atmosphere, is where most of them occur. Several hundred kilometers to about 80 kilometers (50 mi) above the Earth's surface is where the thermosphere begins. Auroras are generated when charged solar particles such as electrons and protons interact with Earth's magnetic field and strike atoms and molecules in the thermosphere.
Therefore, the correct option is D.
