55. In cocker spaniels, black coat color (B) is dominant over red (b), and solid color (S) is dominant over spotted (s). If Bb S
s were crossed with Bb ss, the chance that a black solid individual would be produced is a. 3/16. b. 1/3. c. 9/16. d. 3/8. e. 1/16.
1 answer:
Answer:
d. 3/8
Explanation:
Black coat color (B) is dominant over red coat color (b) and solid color (S) is dominant over spotted color (b).
BbSs was crossed with Bbss
BbSs x Bbss
Offspring:
<em>2 BBSs black, solid</em>
<em>2 BBss black, spotted</em>
<em>4 BbSs black solid</em>
<em>4 Bbss black, spotted</em>
<em>2 bbSs red, solid</em>
<em>2 bbss red spotted</em>
Total black solid = 6
Hence, the chance that black solid individual would be produced = 6/16 = 3/8.
The correct option is d.

Answer:
<u>B) decreased rates of photosynthesis</u>
Explanation:
Plants, phytoplankton, algae, and other microorganisms photosynthesize using energy in the form of solar radiation. Photosynthesis is a chemical process that's integral to these organisms, which are called producers.
They combine light energy from solar water and carbon dioxide, in a complex process that produces chemical energy in the form of glucose.
Photosynthesis is a rate-limited reaction; it depends on various factors including carbon dioxide availability and light intensity. When light is limited, the rate of photosynthesis decreases due to its slowing effect on the light-dependent reaction in photosynthesis, occurring in the chlorophyll.
