Answer:
Phospholipids contain phosphate and glycerol in addition to fatty acids. They are the main component of cell membranes in all living things. Steroids are lipids with a four-ring structure. Some steroids, such as cholesterol, are important components of cell membranes.
1) all the possible genotypes are also identified by color in the image below :AABBAAbB or AABbaABB or AaBBaAbB or aABb or AabB or AaBbAAbb
aAbb or AabbaaBB
aabB or aaBbaabbThere are 9 different genotypes in total. These can be achived by mixing the alleles of both genes of each parent (just like it's represented in the square).
2) there are 4 phenotypes
-one with an allele A and allele B that would dominate the other. (AABB, aAbB, for example)
- one with all alleles recessive- aabb
-one with the recessive alleles in the gene A but heterozygotic/homozigotic dominant for gene B ( for example: aaBB)
-one with the recessive alleles in the gene B but heterozygotic/homozigotic dominant for gene A ( for example: Aabb)
3) <span>probability of having offspring with the aabb genotype: 1/16
Just by looking at the punnet square, you can see that only one has the aabb genotype, in all the 16 possibilities.

Embryo should be the answer

Almost the entire system of an embryo is made of cartilage,
whereas that of an adult is mostly made of bones.
<span>An </span>embryo<span> <span>is a
multicellular diploid eukaryote in an early stage of embryogenesis, or
development. In general, in organisms that reproduce sexually, an </span></span>embryo<span> develops from a zygote, the single cell
resulting from the fertilization of the female egg cell by the male sperm cell.</span>
<span>Biologically, an </span>adult<span> is a human being or other organism that has
