Answer:
I wasn't sure what you were asking
Explanation:
The fluid mosaic model explains various observations regarding the structure of functional cell membranes. According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.
The best answer would be:
Unconditioned stimulus
In Pavlov's experiment on conditioning the food was the unconditioned stimulus that triggers a reflex or natural behavior. Think of it like something that makes you do something automatically.
For example, the food. When the dog smells food, it salivates. This is unconditioned because without teaching the dog, it automatically responds by salivating.
Hey there! :D
If you were told to describe the science of something, that means you should describe how it works. One definition of science could be the understanding of how the world works. So, if someone asked you the science behind why Hydrogen Peroxide helps clean your cut or injury, you could say that it is because of a reaction between the proteins in your skin and the hydrogen peroxide. The fizzy oxygen bubbles are the product. In turn, it kills some of your somatic (body) cells, but also kills bacteria. That is an example of what someone means to describe the science of something.
I hope this helps!

Answer:
b) Forming zygots
Explanation:
A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.
