1- Reactants (H = 2, O = 2)
Products (H = 2, O = 0)
2- Reactants (P = 4, O = 2)
Products (P = 2, O = 3)
So basically if it was H20, then there is 2 Hydrogen because the two is in front of the H and there isn’t a 2 in front of Oxygen.
However if it was H2O2, then there is two hydrogen and two oxygen because there is a two on both of the symbols which indicates how much reactants/products there is.
Hope this helps!
Answer:
3. haploid; diploid
Explanation:
Sperm is male gamete or often called male reproductive cell. During the process of spermatogenesis, reductional division (meiosis) occurs in the spermatocytes and spermatids are formed which further mature to sperms. Thus as a result of meiosis, their chromosome number is reduced to half and thus they become haploid cells. During oogensis, eggs are also formed as a result of meiosis which reduces the chromosome number and so eggs are also haploid.
When during fertilization, these two haploid nucleus of these cells fuse together, they form a diploid zygote.
D. 9
Notice that diploid cells
which 18 are the complete number of chromosome pair of the organism. This usually
happens under cell divison –mitosis which process of replicating oneself to
produce another like cell. Meiosis occurs in gametes, sex cells. Their respectively
called spermatogenesis (sperm cells) and oogenesis (egg cells). These cell
division –meiosis produces haploid cells, in which in words “half” from the
complete cell chromosome number, hence, these haploid cells only produce half number
or one set of chromosome (9) instead of the complete pair which in this case,
18.
Diffusion is a process that occurs when a substance such as water, molecules, and ions, which are usually needed for various cellular processes, enter and leave cells. The way that cell diffusion happens is by molecules moving from an area of high concentration to an area of low concentration. This usually occurs until both molecules have the same amount of the substance and it is distributed evenly.
