Raul plans to start jogging after being sedentary for 2 years. what is the first step he should take? make sure he is medically

Gekata [30.6K]

The right answer is: practice warming.

If Raul starts jogging after the cessation of activities for a reason such as lack of time, lack of desire, injury (or a pregnancy in women):
He must insist even more on warming up, it's twice as important when his body is not used to sport. The sensations felt will serve as an indicator. The more he warms up, the less body aches the next day.
Progressing slowly instead of doing too much exercise for your body.
Listen to his body and pay attention to injuries.

Which statement is true about the male reproductive system?

umka21 [38]

Answer:

C. The scrotum functions to keep the testes at an optimum temperature.

Explanation:

In order to understand the correct answer, we need to review basic anatomy and physiology of male reproductive system.

Testes also known as testicles are paired organs located in the scrotum (bag of skin and smooth muscle) suspended from the body. Testes are responsible for the formation of sperms. Scrotum keeps the testicles away from the body. It provides a temperature cooler than the body temperature which is necessary for formation of sperms (Spermatogenesis). Sperms mix with other secretions from various internal genital organs (prosate, Cowper's glands, seminal vesicles) to form semen. Sperms constitute a very small proportion of semen.

Semen is deposited by the penis into vaginal tract from where the sperms travel to uterus.

Coming back to the answer choices,

A. The testes produce semen.

Testes produce sperms and semen is formed after sperms mix with other secretions of organs of male reproductive system.

B. Sperm cells are the largest component in the composition of semen.

Sperms constitute a small proportion of semen. Other components of semen include fructose, fibrinogen, coagulants, cholesterol etc.

C. The scrotum functions to keep the testes at an optimum temperature.

This is the correct answer choice as scrotum keeps testicles away from the body at a suitable temperature for spermatogenesis.

D. The penis enables sperm to be deposited directly into the uterus.

Penis deposits semen into the vaginal tract from where sperms travel to the uterus.

Present an argument in favor of bioengineering.

GrogVix [38]

Bio-Engineering is the use of living vegetation, either alone or in conjunction with civil engineering structures and non-living plant material, to reduce shallow-seated instability and erosion.

Explanation:

DEVELOPMENT OF BIO-ENGINEERING:

In Germany and Austria wishes to use the low-cost local materials and traditional constructions due to their Financial restrictions of pre-war years 1930's

ADVANTAGES OF BIO-ENGINEERING:

Re-establishing vegetation and store the hydrology from the surface to control of accelerated erosion.

Cost-effective treatments:

landslides
Roadside failures
River stream banks
mining reclamation.

EXAMPLE:

GRASS PLANTING

Usually planting the large grass clumps in lines across the slope.

Horizontal lines are used to increase the protection against erosion.
