Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
Answer:
B carbohydrates
Explanation:
Your cells convert carbohydrates into the fuel molecule ATP through a process called cellular respiration.
Considering the choices;
A. blood glucose level and pH
B. amount of light and temperature
C. amount of light and pressure
D.
temperature and pH
Answer;
D.
temperature and pH
The two factors affect an enzyme's operation the most is the temperature and pH.
Explanation;
Enzymes work best at optimum pH and temperature.
At low temperature for example the enzymes are inactivated while at high temperatures enzymes are denatured.
At optimal temperature and pH; the chemical reaction rate is optimal.
They are mostly habittated to watter because they requres oxygen more from water or there organ setup to do it works properly under water.
Oogenesis and spermatogenesis both involve the chromosomal-reduction divisions of meiosis,which takes the gametes from the full complement of chromosomes to the Haploid number of chromosomes. Meiosis is the type of cell division that take place in the gamete cells, where diploid cells of the germ lines undergo cell division to yield haploid cells, normally the gametes are made through this process, that is, the ovum through Oogenesis, and the sperm through spermatogenesis. During fertilization the two combines to produce a diploid cell once again that undergoes continuous mitosis to form a zygote.
