NO evolution is not real cuz it states that a fish can just choose it dosent want to be a fish anymore so it changes that dosent make sense
Answer:
1. lactic acid, 2. varicose veins or spider veins, 3. posture, 4. muscle fibers, 5. range of motion, 6. muscle myofibrils
Explanation:
1. usually happens during anaerobic metabolism reactions, there is sufficient O₂ to decompose the glucose and glycogen formed during exercise.
2. these veins are common in older women and usually are formed as a result of standing for too long. The semi-lunar valves weaken in the leg, and therefore blood does not get caught in those valves but escapes downwards and then collects resulting in those thick or swollen looking veins, or it is hereditary.
3. this is the manner in which you keep your body and its muscles in place or basically how one 'carries their body.'
4. the human skeletal muscle is made of these muscle fibres which add density and support to the bones along with the veins and nerves
5. this is the specified amount of movement a body is able to do, each individual has a different range of motion, the older one gets, the less of a range there is present.
6. is kind of a 'monomer' for muscles, it is the 'basic unit' and is rod shaped. Each rod has thick and thin filaments within them.

Answer:
Postzygotic reproductive barriers
Explanation:
Post-zygotic reproductive barriers are the adaptations developed in the organism which occur after the zygote (fertilization product) has been formed.
The Post-zygotic barrier involves the hybrid inviability which refers to the reduction on the viability of the offspring and hybrid sterility or that is the production of the fertile reproductive barriers.
The production of mule by the mating of horse and donkey results in the infertile mule which is considered the mechanism of the post-zygotic barrier.
Thus, Postzygotic reproductive barriers are the correct answer.
Most of earth’s fresh water is stored in polar ice caps/ glaciers
