Your question is rather unclear but from what I can tell either there were not an even amount of Petri dishes or some of them were left open while others were not.
1. peripheral resistance
2. vessel elasticity
3. blood volume
4. cardiac output
Answer:
The correct answer would be a loss of sensation to pressure and touch.
The dorsal column-medial lemniscus pathway abbreviated as DCML refers to the sensory pathway of the central nervous system (CNS) which transmits sensations of vibration, fine touch, proprioception, and two-point discrimination from the skin as well as joints.
Thus, injury to the dorsal column would result in the loss of sensation to touch and pressure.
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
