2.1 a) nectar b) to produce seeds c) pollen is made in the ovary
Answer:
Proteins play a fundamental role for life and are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge amount of different functions.
The passage of DNA to proteins begins with the step of transforming genetic information into an intermediary between DNA and protein. This intermediary is called messenger RNA (mRNA). The difference between DNA and mRNA is that the second corresponds to a very small fraction of all DNA, consists of a single chain (it is no longer a “zipper” but a strand), and that Thymine (T) is replaced by the Uracil (U). This fraction corresponds to the stretch of DNA that contains the sequence necessary to ultimately synthesize the protein.
Answer:
Both options are valid, since in the hypothesis of the savanna it was argued that humans acquired bipedalism to be able to self-supply their food more effectively, and to have less body surface area exposed to the sun.
Explanation:
The saban hypothesis is believed to have originated in the saban, with the Austrolopitecus africanus being forced to affect this domain, which is why it acquired this adaptation mechanism.
The savanna had high grasslands, which also led to collaboration in this regard since they could be better camouflaged.
In addition, the human began to defend with the limbs of the upper limb, triggering the canines to decrease in size since it is not used as a defense mechanism.
The canine is a tooth that helps to tear carnivorous food, that is why the human also begins to have a more varied diet of fruits and seeds and that it can reach and take the bones of the tree to increase its height due to bipedalism.
<h2>Functions of elbow joint </h2>
Explanation:
- The elbow joint should be rotated laterally.
- This is because the elbow is basically a pivoted joint, however, it has the extraordinary capacity to turn the distal arm in pronation and supination
- These exceptional movements, alongside a wide scope of dynamic exertional powers, incline the elbow and its structures to critical wounds, especially with tedious movements
- Understanding the life systems and the physical powers of development will help in diagnosis
- Hence, the right answer is "elbow joint should be rotated laterally on an (AP), when the radial head is slightly superimposed over the proximal ulna on the first effort"
