Answer:
Because it is a solid that has trapped air with the water molecules in cold temperature thus creating a hard solid.
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.
Answer:
The correct answer is (B) A larger area of the sensory cortex is associated with our lips.
Explanation:
All the sensory inputs that come from the body is received by the somatosensory cortex. Neurons are responsible for sensing the perception of touch, heat, pains, etc on any body part and pass the information to the somatosensory cortex where the information gets processed.
Our lips contain many nerve endings and nerves which makes it very sensitive towards touch, warm, and cold. So due to the large number of nerve in lips it is considered as an erogenous zone which states that this area is very highly sensitive. So the correct answer is B.
Answer:
Shows an inversely proportional relationship.
Explanation:
The Boyle's law belongs in the region marked X whereas the other circle belongs to Charles law. There is inverse relationship between the two circles or these two laws because in Boyle's law, temperature is constant while on the other hand, in Charles law pressure is constant instead of temperature. In Boyle's law, pressure of a gas is inversely with its volume whereas in Charles law, the volume of a gas is directly proportional to its absolute (Kelvin) temperature.
