Answer:
The three anatomical structures that, in order, contribute to the production of mature sperm are the epididymis, seminal vesicle and prostate.
Explanation:
The sperm and the first seminal fluid are produced and found initially in the seminiferous tubules of each testicle. From there they move on to several structures that contribute to the maturation process:
- Each <u>seminiferous tubule </u>drives the sperm to the epididymis, through the vas deferens, where the sperm can be for a long time and complete their maturation process.
- From the epididymis, the sperm pass to the seminal vesicle, which produces more seminal fluid to give nutrients to the sperm and facilitate its movement.
- Finally, and before being expelled outside, the seminal fluid receives the prostatic secretion in the prostatic urethra, a viscous and whitish liquid that completes the seminal fluid content.
The process of maturation of sperm is of importance for the process of sexual reproduction.

Bird skeletons are very delicate, and therefore, difficult to be preserved. The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.
The overexpression results in increased micro vessel density and lesion size in mice with induced endometriosis.
Endometriosis is a benign gynecological disorder.
- it's far characterized through the ectopic presence of endometrial glands and stroma out of doors of the uterine hollow space and is carefully related to dysmenorrhea, pelvic pain, and subfertility.
- In endometriosis, the involvement of vascular endothelial mobile growth issue (VEGF) and different angiogenic mediators has long been recognized endometriotic angiogenesis entails numerous pathways and the blockade of simply one single pathway won't effectively suppress Endometriosis
- Slit is a secretory glycoprotein which include 3 members, Slit1, Slit2, and Slit3, and become at first found to be secreted repellents in axon steerage and neuronal migration It has been shown to be an endogenously available inhibitor of leukocyte chemotaxis.
- receptor for Slit is the protein Roundabout (ROBO), which currently includes 4 members (ROBO1-4)

Answer:
I think the answer is the first option, more reliable and harder to use.
Explanation:
I think this because technology is expensive and the most reliable thing we have right now so the other options don't make sense.
Answer:
Arteries
Explanation:
There are three main types of blood vessels: veins, arteries, and capillaries. Arteries are the blood vessels that carry the oxygenated blood from the heart to various body parts. Veins pick the deoxygenated blood and deliver it to the heart to be oxygenated.
Arteries are the blood vessels with thick walls and no valves. Blood is pumped with higher pressure from the heart into arteries. The pulmonary artery is the only exception that carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
