<span>Genes -- and, thus, the traits they code for -- are passed from parent to offspring. From generation to generation, well-understood molecular mechanisms reshuffle, duplicate, and alter genes in a way that produces genetic variation. This variation is the raw material for evolution.</span>
Answer: option c is the correct one

2)Plantae=>autotrophic multicellular eukaryotes with cell wall
Answer:
C. two tetramers of histone proteins
Explanation:
The nucleosome core particle is responsible for packaging DNA in the chromosomes. The protein components that make up the nucleosome core are two tetramers of histone proteins. One of which is composed of two units each of histones H2A and H2B, while the other one is composed of two units each of histones H3 and H4. Thus making up the entire protein component of the nucleosome core.
Answer:
Option (d).
Explanation:
Anagyrine is ab alkaloid that is mainly responsible for the crooked calf syndrome. This chemical effects have been tested on the cattle, goats and sheep.
The researchers has found that anagyrine can work as a teratogen. This chemical can cause birth defects in an individual. The angyrina when ingested by woman causes birth defect during early pregnancy.
Thus, the correct answer is option (D).
Yes this true and they are known as ABIOTIC FACTORS. Some examples are:
• Soil
• Temperature
• Air
• pH
• Water
