Answer:
Semen
Explanation:
Sperm is the male reproductive gamete produced by the testes. During copulation or sexual intercourse, the produced sperm moves along a tube called VAS DEFERENS or sperm duct. The sperm mixes up with fluid called SEMINAL FLUID produced in the accessory glands comprising of seminal vesicles, prostrate gland and the bulbourethral glands to form the SEMEN, which is ejected from the urethra (a tube that runs from the bladder to the penis) during ejaculation.
The seminal fluid that mixes up with the sperm serves to lubricate it for easy locomotion within the female reproductive parts and also provide nourishment for the sperm.
Answer:
D. archaeal membranes contain L-glycerol.
Explanation:
Archaea and eubacteria differ from each other with respect to the nature of membrane lipids. Lipids present in the membranes of the archaeans have the hydrocarbons derived from isoprene units. These hydrocarbons are branched and are attached to the glycerol with help of ether linkage. Ester linkages are present in eubacteria. The glycerol present in the archaeans is L- glycerol. Bacterial membranes have D-glycerol present in their lipids.
Answer:
it produces 38 atp from 1 molcule
Ganglion cells and Lateral geniculate nucleus.
- Ganglion cells: Also called ganglion neurons, are essential nerve cell for vision; they receive information from photoreceptors using bipolar, amacrine and horizontal intermediary neurons.
- Lateral geniculate nucleus: It is the primary processing center of the visual information received by the eye, in addition it is in charge of the regulation of the flow and intensity of the visual signals that are transmitted to the visual cortex.
