Biology

Sergio [31]3 years ago

<h3><u>Answer and explanation;</u></h3>
  • DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
  • <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
  • <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
  • Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.

Cannabis (marijuana) during pregnancy is dangerous for the fetus

During pregnancy, the active component of cannabis, which is THC (tetrahydrocannabinol), can go into the placenta and affect the fetus, including its birth weight (like the case in the question here) and brain function, reducing the baby's IQ and attention capacity.


Depending on the type of drug and the quantity consumed, it is also possible that the baby suffers from weaning at birth, that is to say from deprivation (inconsolable crying, irritability, tremors, feeding difficulties, etc.). .


Cannabis may also have longer-term effects in children (learning disabilities, behavioral problems, hyperactivity, etc.).

The trait of the dental gap is present in apes but absent in hominins.

<h3>What do you understand by hominins?</h3>

The term "hominin" refers to a group that includes all living humans, all extinct human species, and all of our direct predecessors (including members of the genera Homo, Australopithecus, Paranthropus, and Ardipithecus). Sahelanthropus, Orrorin, and Ardipithecus are the earliest hominins. Many characteristics that set humans apart from other primates were absent in the ancestors of the human lineage. Sahelanthropus tchadensis from the Chad and Orrorin tugenensis from Kenya are the oldest hominins that are currently known. The skull of Sahelanthropus, which dates to between 6 and 7 mya, is mostly complete, and there are also some additional fragmentary bones.
