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.
Answers
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.
What are the adaptation rabbits have in Himalayan?
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

Answers
Answer:
c. the yolk is the correct answer.
Explanation:
The yolk part of the amniotic egg provides food for the embryo.
The yolk sac is present inside the egg and it provides nutrients to the developing embryo.
The yolk is the main source of nourishment for the embryo and carries all the fat.
The yolk part provides protein, energy, and water to the embryo.
yolk part becomes the umbilical cord through which food reaches the fetus and waste substances are removed.

Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
Some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Answers
Answer:
The correct answer is "Some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited".
Explanation:
Antibiotic resistance is a serious health issue that occurs when bacteria gains resistance against certain antibiotics, which reduces or eliminates the effectiveness of the treatments. The best explanation for this phenomenon is that some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited. This happens particularly when people do not take the full treatment or take treatment without diagnosis. In consequence, the populations of bacteria are not fully eliminated, increasing the probability of survival for bacteria that randomly mutates towards resisting the treatment.
