Answer:

The most appropriate answer would be D) crossing over of homologous chromosomes during meiosis.

Crossing over is the event that takes place during the pachytene stage of prophase 1 of meiosis 1.

During this event, genetic material is exchanged between the non-sister chromatids of the homologous chromosomes.

The homologous chromosomes assemble near each other in a synapsis. The tetrad or bivalent is formed during this period.

The point of contact where the actual exchange of genetic material takes place is termed as chiasma.

Crossing over results in new combination of genes different from either parent.

Amphiarthrodial joints display ___ movement than synarthrodial joints.
Misha Larkins [42]
The answer to this question would be more movement.

The amphiarthrodial joint is a joint that you will found in the rib cage. This joint doesn't have a synovial cavity and only allow a little movement.
But synarthrodial joints movement is practically zero. The example for <span>synarthrodial joint would be suture in your skull. Skull joint in adult can't move so its volume can't be changed.</span>

Neurons that carry impulses from the eyes to the spinal cord and brain are called 5. motor neurons carry impulses from the brain
earnstyle [38]
<span>4. The neurons that carry impulses from the eyes to the spinal cord and brain are called the Sensory neurons. Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.

 5. Motor neurons carry impulses from the brain and spinal cord to and from the Muscles and glands. The motor neurons transmit impulses from the spinal cord to skeletal and smooth muscles, and therefore directly control all of our muscle movements. There are two types of motor neurons, those that travel from spinal cord to muscle (lower motor neurons) and those that travel between the brain and spinal cord (upper motor neurons)

6. The neuron's cell body has short, branched extensions called dendrites. Dendrites are tree-like extensions at the beginning of a neuron that help increase the surface are of the cell body. They receive information from other neurons and transmit electrical stimulation to the soma (cell body). They are also covered with synapses.

7. In most animals and of different neurons are clustered in bundles called nerves Axons and dendrites. Axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal. The larger the diameter of the axon, the faster it transmit information. Most neurons have only one axon, they transmit impulses from the cell body and also may or may not have a myelin covering.

8. The insulating membrane that surrounds a single axon in some neurons is called the Myelin sheath. The myelin sheath is a protective covering that surrounds fibres called axons, the long thin projections that extend from the main body of anerve cell or neuron. It is composed of proteins and lipids. The main function is to protect and insulate these axons and enhance their transmission of electrical impulses.</span>
