Answer:
Amino acids.
Explanation:
Miller -Urey experiment was performed by creating the primitive earth condition in the laboratory. The main aim of this test was to determine the chemical origin of the life.
The electrodes was used to create the spark conditions and different gases like water, methane, ammonia, and hydrogen. The product was obtained after some days of the reaction. The amino acids like glutamic acid, glycine, α-alanine and β-alanine was obtained from the product of this experiment.
Thus, the correct answer is option (1).
Although a small amount of variety has been passed down from Neanderthals, most human variation is derived from what was present in the population of homo sapiens that initially appeared in Africa.
<h3>Genes are a good illustration.</h3>
Your skin and hair colors, among other characteristics, are influenced by the genes you inherit. The possibility exists that Emma's mother possesses two genes—one for brown hair and one for red hair—and may have given her one of them.
<h3>Relevance of genes</h3>
The formation and operation of your cells are governed by the instructions found in your DNA. The building blocks of the body are cells. A billion cells work together to form every component of your body. Chromosomes are the structural elements that hold genes in place.

Answer:
a. a plant cell undergoing cytokinesis
Explanation:
Cytokinesis is the process where the cytoplasm divides after mitosis to form two different daughter cells from the parent cell. Animal cell divides by just a cleavage formation. Plant cells have an additional step of formation of cell plate because they have cell wall.
At the end of anaphase and beginning of telophase when the two new daughter nuclei have just formed, cell plat formation begins. Secretory vesicles from golgi body come at equator of the dividing parent cell. These vesicles release all the materials required for cell wall formation. The materials start to form the cell plate which moves outwards till it reaches the division site of parent cell wall. Slowly cell wall arises from cell plate and cytokinesis occurs giving rise to new plant cells.
