How was bipedal locomotion important to hominin evolution?
WITCHER [35]

Answer:

Bipedalism freed the hands so they could be used to cart food,  make and use weapons and other advantages of freed hands.  Bipedalism is a much more efficient way to walk and run and this  fact is quantified.  Bipedalism raised the early proto-human above the horizontal so  he could see predators approaching.  Bipedalism is a much more efficient design to cool down  overheating bodies.

your welcome :)

True or False. By using cuttings, exact genetic characteristics can be maintained.​
Brrunno [24]

Answer:

It is true to say that by using cuttings, exact genetic characteristics can be maintained, because the cuttings retain the same genetic information about the plant from which they were extracted.​

Explanation:

Cuttings are buds or branches extracted from a plant to obtain a plant of the same species, through a type of asexual reproduction.

Once separated from the "progenitor" plant, the cutting is provided with a suitable medium for growth, and will have the possibility of growing roots, developing and growing as an independent plant, with the same genetic characteristics of the original plant, as if it were a clone.

In this reproductive process, man intervenes.

The seeds an evolutionary advantage for seed plants because seeds develop into adults without sxual reproduction.

<h3>What is the evolutionary importance of the seed?</h3>

Seeds play an important role in the dispersion of plant species, that is, they ensure that plants spread throughout the environment. In addition to guaranteeing a greater area of ​​domain for the species, competition between the newly born plant and the mother plant is also avoided.

Seeds allow the expansion of a type of plant around the world in addition to being a form of asexual reproduction that makes it unnecessary to join gametes.
