The shortening and broadening of pelvis in hominins was the indicative of habitual bipedal locomotion.
Hominins are the tribe that belong from the sub-family Homininae. They are considered as the first modern humans. They are believed to be our recent ancestors. Homo sapiens species is evolved from this tribe. The various anatomical evolutions in them were: erect posture , larger brains, bipedal motion, broadened pelvis, usage of tools and also they were known for communication.
Pelvis is the area between the lower abdomen and the hip bone. It comprises of bladder and rectum. Some of the reproductive organs of the males and females are also located in their respective bodies.

Answer: Behavioral genetics
Explanation: This concept indicates that our genes influence our environment and in return, the environment influences our genes. Behavioural genetics has therefore expressed gene-environment interactions on the behaviour of an individual.
Answer:
- New seedlings: histone acetylation
- After cold exposure: histone methylation
Explanation:
Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In <em>Arabidopsis</em>, vernalization is associated with histone modifications at <em>FLC</em> chromatin. The <em>FLOWERING LOCUS C </em>(<em>FLC</em>) is a MADS-box gene that acts as a repressor of flowering in <em>Arabidopsis</em>. Epigenetic modifications control the expression of the <em>FLC</em> gene. The <em>FLC</em> gene is expressed at low temperatures due to histone acetylation at <em>FLC</em> chromatin, and thereby the expression of <em>FLC</em> mRNA transcripts ensures that the <em>Arabidopsis</em> plant cannot flower. Subsequently, as the <em>Arabidopsis</em> plant is exposed to cold, <em>FLC</em> is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.

Answer:
Stage III Interpretation
Explanation:
There are three stages of perception process
• Exposure
• Attention
• Interpretation
During perception, the sensory receptors are active and they receive stimulus from their surroundings. However, the complete perception of any stimulus is interpreted by the brain because only brain is capable of differentiating between the sensory stimulus based on the pathway followed by them. On the basis of perceived information, action potential signals are generated that are sent back to the sensory organ (perceiving the stimulus at their end) for further responses.
