Differences in gene expression in multicellular organisms arise primarily from the regulation of gene activity, which is influenced by factors such as transcription factors, epigenetic modifications, and the cellular environment. These regulatory mechanisms allow cells to respond to internal signals and external stimuli, leading to distinct cell types and functions despite having the same DNA. Additionally, cell signaling pathways and interactions with neighboring cells play crucial roles in orchestrating gene expression patterns during development and in response to changing conditions.

The differences in gene expression in multicellular organisms are primarily driven by regulatory mechanisms that control when and where specific genes are activated or silenced. Factors such as transcription factors, epigenetic modifications (like DNA methylation and histone modification), and signaling pathways play crucial roles in this process. Additionally, environmental cues and cell-type specific factors can influence gene expression, leading to the specialization of cells and the development of distinct tissues and organs. This regulation allows for the diversity of functions and characteristics in multicellular organisms despite having the same genetic blueprint.
Zygote is the fertilized cell that grows into a multicellular organism in sexual organisms.The embryonic germ layer divides and differentiates into the complex multicellular organism.
Yes they are, zygotes themselves are the product of fusion between two haploid gametes. These gametes fuse in order to develop into a multicellular structure, which they are unable to do unless they fuse. The product of their fusion is a zygote which is able to develop into a multicellular structure.

All organisims are living because, they all have the same characteristics, we need to eat, sleep, have water, excreamate and urinate and that has (or can develop) the ability to act or function independently . Organisims are all mover the place, mammals,birds,reptiles,fungie,fish, plants anything with those characteristics. There are such things as bio organisims. bio organisims are things like rocks, shoes, desks, chairs who can not move independantly, eat, drink, sleep, excreamate or urinate and these objects are not organisims. Happy to help.
Yes, an embryo is multicellular. After fertilization, the single-celled zygote undergoes a series of divisions, leading to the formation of a multicellular structure known as a blastocyst in mammals. This multicellular embryo continues to develop through various stages, eventually forming different tissues and organs.
Sponges are not unicellular organisms but they are multicellular organisms.They belong to phylum Porifera. They lack tissue grade organization hence they are called Parazoa. Sponges are aquatic animal with pores in body . They possess following types of cells; pinacocytes , choanocytes ,amoeboid cells,spongioblasts and fibroblasts.

A way to develop a good facial expression would be to practice in a mirror. Find an image of a good facial expression you would like to mimic and practice it over and over again in a mirror until it is natural.
