Answer: Cell
Explanation:
The cell is the structural and functional unit of life. It is the the most basic level. A life starts from a single cell.
When a male and female gamete(germ cell) fuse together they form zygote. Firstly it is a single cell surviving inside the mother's womb.
Then differentiation takes place and the cell keeps on dividing to form different tissue layers and then organs form which makes a complete baby. Hence, zygote and germ cell are cellular level of organization.
Answer:
The correct option is A. Matter is conserved during the burning of wood
Explanation:
One of the major theories of matter states that the amount of mass at the start of a reaction is equal to the amount of the mass at the end of the reaction.
As in Joan's study, he shows that the amount of carbon atoms remain 840 during each of the combustion reactions. The number of carbon atoms in wood at the start of the reaction was equal to the number of carbon atoms in carbon dioxide at the end of the reaction. Hence, Joan's model supports the theory that matter is conserved during the burning of the wood.

Answer:
Triploid egg
Explanation:
Triploid, with three copies of each chromosome. When a diploid sperm fertilizes a haploid egg cell it causes a triploid zygote, which leads to the chromosomalabnormalities in the zygote.
Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
