The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.
What is the organ system?The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.
Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

Which model represents a possible chemical reaction
Answer: A I think
Explanation: I'am really sorry if i'am wrong
Can anyone help me with these please
Answer:
6. Current = 8.33 Amps
7. Energy = 1200 Joules
Explanation:
Given the following data;
6. Power = 1000 Watts
Voltage = 120 Volts
To find the current flowing through;
Power = current * voltage
1000 = current * 120
Current = 1000/120
Current = 8.33 Amps
7. Power = 900 Watts
Time = 45 minutes to hours = 45/60 = 0.75 hours
To find the energy consumption;
Energy = power/time
Energy = 900/0.75
Energy = 1200 Joules
25 POINTSSS AND BRAINLY THE SELECTED ANSWER IS WRONG BTW
Answer:
The second option
Explanation:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.

Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated
A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.
What is Mutation?A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.
According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.
A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.
Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

beak shape, camouflage, and webbed feet are all examples of which type of adaptation
Answer:
beak shape: used to help an animal eat food like tearing apart food or either cracking nuts.
Camouflage: the color or shape of an animals body helps it blend into its envierment.
weebbed feet: help animal's propel themselves through the water with ease. This can help the animal swim faster to
catch prey or escape a predator. Also, if an animal has to swim long distances,
webbed feet can help it save energy so it can swim farther.

The evolutionary pathways of five species are represented in the diagram below.
Present
{
Past
Whích statement is best supported by the diagram?
А.
Species T and Species U are related to species X
B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.
