The
patellar reflex is the most common example or a spinal reflex. When the knee is
tapped, the nerve that will receives this stimulus sends an impulse to the
spinal cord and relay it to the motor nerve. This sources the quadriceps muscle
at the front of the thigh to contract and twitch up the leg. This reflex contains
simply two nerves and one synapse. The leg will start to twitch up on the other
hand the brain is just suitable aware of the tap and comprehends the situation.
<span>Subsequently the tap, the leg is routinely lengthy
once and comes to rest. The nonappearance of this reflex is problematical and recognized
as westphals sign this reflex might be lessened or absent in lower motor
neuron lesions and during sleep. </span>
Answer:
Snapper population is decreasing
Explanation:
The population is decreasing since the human population is increasing dramatically. As the human population increases, the demand for fish and seafood also increases since humans eat seafood and fish. As the demand for fish increases, fishermen fish for these snappers more often and in bigger loads. Snappers cant reproduce faster than these fishermen are hunting for them and so the population decreases
D.
The block of wood does not stop moving at any time as shown on the chart, so the answer can't be A. or C. and the speed is not increasing so it can't be B.
Sporophyte generation - It is found in both seed and seedless plant. Dominant phase of the life cycle of the seedless plants is diploid sporophyte while in seed plant male and female gametes fuses to produces a diploid zygote which develops into a sporophyte.
Pollination - It occurs in seed plants only
Sporophyte contains male and female reproductive structures - It is found in both seed and seedless plant.
Single fertilization - It occurs in both seed and seedless plant
Sperm cells transported by water to egg cells - seedless plant only
Microorganisms can be defined as the organisms which are seen with the aid of microscope. This category includes the bacteria, algae, fungi, protozoa and viruses. These microorganisms play an important role in the decomposition of the biological materials. The nutrients are also recycled by these microorganisms. the microorganisms bound in a soil serve this purpose. Moreover, the microorganisms, such as algae carry out the process of photosynthesis and make their own food.
Some of the microorganisms have complex relationships with different animals and plants both, which help in their survival.
Hence, the right options will be "carry out photosynthesis, decomposition, and nutrient recycling'.
