Sand is a granular material composed of finely divided rockand mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.[1]
The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastalsettings is silica (silicon dioxide, or SiO2), usually in the form of quartz. The second most common type of sand is calcium carbonate, for example, aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean.
Sand is a non-renewable resource over human timescales, and sand suitable for making concrete is in high demand.[2] Desert sand, although plentiful, is not suitable for concrete, and 50 billion tons of beach sand and fossil sand is needed each year for construction.

The simplest answer would be to look at a punnet square. it gives you the random chance that a trait gets passed on to offspring. it's made off probability of dominant and recessive genes. But it's random in the end.
Answer:
The correct answer would be - AUGCUUAUC
Explanation:
The new mRNA strands are made by the process called transcription that involves an enzyme that helps to copy a segment of DNA or gene to produce a new RNA strand that encodes for the protein. In this process, a new RNA strand copied the complementary to the sequence of DNA strand. It means adenosine is copied into its complementary form uracil in RNA, Thymin to adenosine, cytosine to guanine and guanine to cytosine.
Original strands: TACGAATAG
new RNA strand: AUGCUUAUC
Answer:
The dihybrid ratio we expect in the offspring is 9:7.
Explanation:
This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.
So in this case of complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.
