The answer is epididymis.
Epididymis is a tightly coiled mass of thin tubes that carries sperm from the testes to the ductus deferens in the ale reproductive system. Sperms matures as they pass through the epididymis so that they are ready to fertilize ova by the time they enter the ductus deferens. During the ejaculation stage of emission sperms are moved from the testes and the epididymis, where they are stored, to the beginning of urethra.
Answer:
true
Explanation:
When your eyes are not covered and you are in an area with good lighting, then opening your eyes would certainly be a necessary thing to do to be able to see and this makes your vision to be normal.
According to Leo Gross, you can have a normal vision if you are 20 feet away from a particular spot and you see what a normal person sees on that same spot. There is the Snellen chart one is also expected to read in that position, so maintaining a normal vision means someone has 20/20 vision.
Answer:
1. Green beetles and red beetles exist in the environment.
2. Birds that eat the beetles move into the environment.
3. Red beetles are eaten by birds, but green beetles aren’t eaten.
4. Green beetles pass on their color trait to future offspring.
5. The entire population of beetles eventually becomes green in color.
Explanation:
According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.
Answer:
no because they do not require oxygen to breath and they are only one celled organisms.
