Answer:
d. 6 molecules, 18 carbons total
Explanation:
In a Calvin cycle 3CO₂ is combines with 3 RUBP to form 6 molecules of glyceraldehyde-3-phosphate (G3P). One molecule of G3P has three fixed carbon atoms, Thus to make one molecule of six carbon glucose molecules will take two molecules of G3P. Therefore six turns of the Calvin cycle required to make one glucose.
So, as per question, 6 molecules of G3P will required 18 carbons.
The killer whales primarily feed on the secondary consumers in the oceanic food web.
Explanation:
Killer whales are the tertiary consumers and occupy the highest position in the ocean food web. They are predating carnivores and feed on secondary consumers like other fishes, marine animals like leopard seals, sea turtles, dolphins, sea birds, etc. These secondary consumers in turn feed on primary consumers like zooplanktons, small fishes etc which feed on the primary producers like phytoplanktons. The energy flow is highest at the primary producer level and decreases as it goes up to the consumer levels.
Answer:
A) its elliptical orbit and tilt on its axis
Explanation:
Earth revolves around the sun in an elliptical path. Its axis is tilted to about 23.5° from the vertical.
These two factors determine the global climate on the Earth.
Due to elliptical orbit, the earth is sometimes closer to sun than the rest of the time. When it is closer the global temperature rises by 5 degrees. Due to the tilt of the Earth, seasons occur. The hemisphere which points towards the sun has summers where as which points away has winters.
Thus, the long-term climate change is effected by elliptical orbit and tilt of the axis.
Mitosis occurs in both plants and animals. Only during telophase, in the process of cytokinesis that plant and animal cells differ. Therefore, the statements that apply are: Plant cells divide by means of a cell plate. Animal cells undergo furrowing in mitosis.
<h3><u>Answer;</u></h3>
Carbohydrate
<h3><u>Explanation;</u></h3>
- Carbohydrate is the macromolecule produced during photosynthesis for plant food. Carbohydrate is among the four major macromolecules, others being, nucleic acid, lipids, and proteins.
- During photosynthesis energy from the sun, together with water and carbon dioxide are used to make nutrients or organic compounds such as simple sugars like glucose.
- By using the energy from the sunlight and absorbing the water molecules from the soil, the plant produces glucose molecules. The glucose is a carbohydrate.
