Answer: Nervous system
Happy to help; have a great day! If you liked my answer, please give me Brainliest :)
The brain sends appropriate responses to muscles and glands through the nervous system.
When the brain responds to messages by sending appropriate responses to muscles and glands, it does so through the nervous system.
The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. The brain plays a vital role in processing these signals and sending out appropriate responses.
For example, when you touch a hot stove, sensory receptors in your skin send a message to your brain, which then signals your muscles to quickly retract your hand. This quick and automatic response is coordinated by the nervous system.

Answer:producers convert light energy into chemical energy
Explanation:
B. temporal
C. behavioral
D. selective
hybridization
hand pollination
genetic engineering
2. Which process is the opposite of inbreeding?
pollination
hybridization
seed production
genetic engineering
Answer:
1. The correct answer would be genetic engineering.
With the help of genetic engineering the breeder would select, isolate, and transfer the gene (responsible for vitamin production) from the carrot plant cell to the potato plant cell.
It is then followed by cell and tissue culture to grow the plant with the desirable character. Lastly, plant breeding is done to yield the transgenic line.
2. The correct answer would be hybridization.
Inbreeding refers to the breeding of closely related animals or plants over many generations.
In contrast, hybridization is the practice of breeding in which organisms of different varieties or species are cross-breed to produce a hybrid breed or variety. It helps in transferring a desired character from one variety to the other.
2) Mercury
3) Earth
4) Mars
Please explain
The planet that has the lowest average density is Mars. The correct option is 4.
The entire mass of a region divided by the total volume of that region yields the mean or average density.
By multiplying each compound's density by its volume and then dividing the result by the sum of all the volumes, one can determine the mixture's average density.
The average density of different planets is:
Venus; 5.2
Mercury; 5.4
Earth; 5.5
Mars; 3.9
So, the lowest density out of these planets is Mars. Density is something's concentration. If the density is low, the weight of the object will be low. When placed in water, an object will float if its density is lower than that of the water, whereas it will sink if its density is higher.
Therefore, the correct option is 4) Mars.
