Plants maintain homeostasis by keeping their stomata open just enough to allow photosynthesis to take place but not so much that they lose an excessive amount of water.
When plant cells use the food they make, the cells respire, taking in oxygen and giving off carbon dioxide.

Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.
Hope this helps!
Answer:
b. It converts messages that are received from the central nervous system into involuntary reflexes.
Explanation:
The somatic nervous system (SNS) is part of the peripheral nervous system (SNP), which is responsible for transmitting motor and sensory information both back and forth to the central nervous system (CNS).
The main function of the somatic nervous system is to connect the central nervous system to the organs, muscles and skin. This allows us to perform complex movements and behaviors. Somatic neurons carry messages from the external areas of the body that are directly related to the senses. The information captured by the sensory systems is transmitted to the central nervous system. The CNS then sends signals through the nervous networks of the somatic system to the muscles and organs.
Under a microscope, gram-positive bacteria (when dyed with the gram stain) appear in purple-colored structures due to the peptidoglycan cell wall.
<h3>What are gram-positive bacteria?</h3>
Gram-positive bacteria are microorganisms (bacteria) that may be colored with crystal violet stain due to the presence of a peptidoglycan-based cell wall.
In conclusion, under a microscope, gram-positive bacteria (when dyed with the gram stain) appear purple-colored structures due to the peptidoglycan cell wall.
