Answer:700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range.
Explanation:The wavelengths of the visible spectrum are usually between 400 nm and 700 nmn with the the rays of red light having a longer wavelength, and blue light rays having shorter wavelengths. The red light has a low frequency of about 405–480 THz and , blue light has a higher frequency in the range of 620–680 THz. This is due to the inverse relationship between wavelength and frequency which also occurs betwwn wavelength and energy of light rays with the red light having less photon energy of about 1.65–2.00 eV and the blue light with high energy photons of about 2.64–2.75 eV.
Red light can be employed in the photosynthesis in plants as it helps in formation of flowers and the production of fruits. Blue light also is important in the production of chlorophyll and can cause a healthy and strong stem and leaves in excess exposure.
Answer:
B
Explanation:
Carbon Dioxide is one of waste produced from Our cells during respiration. The circulatory system carries Carbon Dioxide from cells either in haemaglobin in RBC or plasm. The Carbon Dioxide being carried to blood cappilaries near alveoli before diffused into alveoli and then being removed away by respiratory system in the process of respiration while we exhale
Answer:
A-) 8 Atoms
B-) 6 Atoms
C-) 16 Atoms
D-) 24 Atoms
Explanation:
A) Na (1 Atom) C2 (2 Atoms) H (1 Atom)O4 (4 Atoms)
1 + 2 + 1 + 4 = <em>8 Atoms</em>
B) H (1 Atom) 2F( 2 Atoms) 2B (2 Atoms) Li (1 Atom)
1 + 2 + 2 + 1 = <em>6 Atoms</em>
C) 2 He2 (2 Atoms) P (1 Atom) S1 (Atom) O4 (4 Atoms)
2 . ( 2 + 1 + 1 + 4 ) = 2 . 8 = <em>16 Atoms</em>
D) 3 He2 (2 Atoms) O4 (4 Atoms) P (1 Atom) H (1 Atom)
3 . (2 + 4 + 1 + 1 ) = 3 . 8 = <em>24 Atoms</em>

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.
