Answer:
Gigantopithecus could stand on its hind legs, and the known jaws of Gigantopithecus widen towards the rear and proposed that this widening occurred to allow for the housing of a trachea (the ‘windpipe’ that connects the lungs to the mouth opening) when the skull was placed directly in top of the head like a human and not carried forward like a great ape.
Answer:
Light reactions and Calvin Cycle
Explanation:
The products of the light reaction become the products of the Calvin cycle (which is the dark stage) of photosynthesis. The light reaction is called so because it harnesses the energy of the sunlight photons to split water molecules into H+ and O- . The CO2 is then reduced to glucose using the H+ in the Calvin cycle without the need for sunlight - hence referred to as the dark reaction. The light reaction occurs in the grana while the dark reaction occurs in the stroma.
In sexually reproducing animals, once fertilization of the egg takes place, the ___________ exists as a single cell until cell division begins.
D) zygote
Answer:
If a species has a number of chromosomes 2n = 18, then its somatic cells have 16 autosomes.
Explanation:
Somatic cells are diploid, that is, they have the complete chromosomal charge, and it is represented as 2n. In organisms with sexual reproduction the chromosomes are divided into autosomes and sex chromosomes, which are 2.
<u>If a species has a number 2n = 18, it means that its somatic cells have 18 chromosomes, of which 16 are autosomes</u> and 2 are sex chromosomes. Autosomes contain the structural and functional characteristics of an individual, while the sex chromosomes determine sex.
