The right answer is D.
A gamete is a generally haploid reproductive cell specialized in fertilization, or gamy (that is to say, able to fuse with another gamete, complementary type if necessary), in eukaryotes.
The process that carries out the fusion of two gametes is called fertilization or gamy, it is the complementary event of meiosis. Fertilization produces a new single cell, called a zygote, whose chromosome number has doubled to 2n.
Answer:
Reflexes are not a function of the spinal cord.
Explanation:
The spinal cord is part of the central nervous system and is made up of neurons that go along it (from the end of the brain stem almost to the bottom of the spine).
The spinal cord receives incoming messages from the peripheral nervous system (including the sensory neurons) and pass on messages from the brain to efferent neurons (motor neurons at muscles).
The spinal cord contributes to learning as it passes on the info received from sensory neurons (that there is an obstacle in the path) to the brain and passes on the response from the brain to the muscles (to lift the foot up higher).
The spinal cord is essential for integration as it passes on sensory information to the brain to determine motor output.
Reflexes are when sensory information is quickly sent straight to motor neurons to move. It does not need to go to the brain (hence does not need to go to the spinal cord) for the reaction as it would be too slow. This is seen when someone who is paraplegic (paralysed at lower torso) can still move their leg in response to the doctor tapping their knee even when they cannot forcibly move their legs.
Therefore reflexes are not a function of the spinal cord.

How do pseudopods work?The Function of Pseudopods. Pseudopods are actually extensions of the cytoplasm, or the thick liquid that is inside organisms like amoeba. The organism can change the shape of the pseudopod, making it move, appear, and disappear. The pseudopods are used in movement and as a tool to capture prey.
To easy remember it,
Phloem, has the (f) sound, so it carries food and nutrition like sugars all around the plant, up and down movwment.
while Xylem carries water and minerals, from down the soil up to the plant, only up movement.
