Answer: Option C is false.
Archaea are not multicellular but they are unicellular.
Explanation:
Archaea are unicellular, microscopic organisms and have similar structure with bacteria.
They are prokaryotes and do not have cell organelles and Nucleus but they have cell wall which lack peptidoglylcan.
They have membranes that enclose lipids. They are obligated anaerobes that live in environment with low oxygen like water and soil.
Examples include methane loving methanogens, halophiles( salt tolerant), thermophiles (heat tolerant ) and pschrophiles ( cold dwelling). They are mostly found in extreme environment.
For photosynthesis you will need co2 water and sunlight to produce oxygen and glucose
Answer:
The person was born in 2005 B.C. (Before Christ). Therefore, he was 5 years old in 2000 B.C, 10 in 1995 B.C, and 15 in 1990 B.C.

Answer:
It is a trait highly influenced by environmental factors (i.e., it has low heritability)
Explanation:
In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.
