Answer:
A) Plants can’t photosynthesize at night.
C) Plants need ATP production for the entire day.
Explanation:
A) is correct. Photosynthesis occurs only in daylight hours.
B) is wrong. Photosynthesis peaks at noon when the sun is at its peak.
C) is correct. Plant respiration occurs both day and night.
D) is wrong. Photosynthesis begins at sunrise.
Answer:
When animals eat their food combine with oxygen, which produces energy for the animals to use for everyday activity and then gives off carbon. The carbon then combines with the oxygen to form carbon dioxide, which is then released back into the atmosphere as waste product when the animals breath.
Carbon Dioxide (CO2)
Hope this helps ;)
Headache and Fatigue.
Good luck! (:
Answer:
Explanation:
Im not 100% sure, but I think that because the snake venom gets stronger, other species that have adapted to the weaker venom have a harder time fighting it. For example, the honey badger can fight of snake venom with its very thick skin and ability to sleep it off. However, if the snake venom got stronger/deadlier, the honey badger would have a much harder time fighting it, and might die.
Answer:
152.88 solar unit.
Explanation:
The haploid genome content of the human cell is 3.3 x 10⁹ bp but the human cell is diploid.
So, the content of the diploid cell = 2 ×3.3 x 10⁹= 6.6×10⁹ bp/cell.
1 cell contains DNA = 6.6×10⁹ bp/cell.
10¹³ cell DNA content = 10¹³ x 6.6×10⁹ = 6.6 x 10²² or 6.6 x 10¹⁹ kilo base pairs.
1 kilobase pair of DNA = 340nm = 340 × 10⁻⁹m.
6.6 x 10¹⁹ kilo base pairs of DNA = 340 × 10⁻⁹ × 6.6 x 10¹⁹ = 2244 x 10¹⁰m.
1 meter= 6.2 ×10⁻⁴ miles.
2244 x 10¹⁰m = 6.2 ×10⁻⁴ × 2244 x 10¹⁰m = 13912.8 ×10⁶ miles.
1 solar unit = 9.1 x 10⁷miles.
Then 13912.8 ×10⁶ miles = 13912.8 ×10⁶ miles/ 9.1 x 10⁷miles = 152.88 solar unit.
Total human DNA in terms of solar unit = 152.88 solar unit
Thus, the answer is 152.88 solar unit.
