Answer:

is a blind, neutral experiment

Explanation:

In Science, to have results in which you can trust, always need to be a comparative ( in this case the creatinine supplementation and the other powder). To be a serious experiment, need to have the same activities, duration and the participants need to "blind" to know which substance they are really taking, so they need to train as usual, and after some time the results will show if there is a significant difference.

Explain why the effect of stimulant and depressants do not necessarily counteract<br>each other​
Ivahew [28]

Answer:

Even though the symptoms of the stimulants and depressants are quite opposite, the causes of these symptoms are completely unrelated. A stimulant could cause one area of the brain to release a chemical and a depressant could affect a completely different area of the brain. They don't have to counteract each other.

Which of the following is not part of the male <br> reproduction system
Tomtit [17]

Answer:

The correct answer for the question is The Bartholin’s glands

Explanation:

The male reproductive system includes the primary organs which produce male gametes and the accessory organs which do not produce the gametes but are involved in the reproductive process. The Bartholin’s glands are located near to the vagina which is the structure associated with the female reproductive organs, therefore, is considered the part of the female reproductive system.

Further explanation:

The reproductive system is a system formed by the sex organs which work in a coordinated manner to facilitate the purpose of the sexual reproduction in humans.

The human reproduction takes place by sexual intercourse which involves the process of internal fertilisation.

The male reproductive system is a system of sex organs which involves the structures which produce the male gametes and the accessory organs which help the transfer of the gametes to the female sex organs.

The primary male gamete producing sex organs is known as the testis enclosed in the scrotum which provides a site for the sperm production and maturation. The sperms are produced by the process of spermatogenesis which takes place in the seminiferous tubules surrounded by the Sertoli cells which matures into sperms.

The epididymis is a narrow tightly coiled structure which provides the site for sperm maturation and the storage. The epidydymis connects the testis to the Vas deferens.

Vas deferens is the partially coiled tubular structure present which transfers the sperms to the ejaculatory tubules including the seminal vesicles, urethra and penis of the male reproductive structure.

The Bartholin’s gland or the Bartholin gland is located in the posterior position to the left of the vagina (a part of the female reproductive system) and is involved in the process of the production of the mucus which lubricates the vagina during sexual intercourse.
