Continents has shifted millions and million years ago
Answer:
C. All of the answer choices are correct.
Explanation:
Option A is correct because the reproduction of the cell implies arrangement of chromosomes, making of proteins, organelles, cytokinesis and other cells process that need energy since the mitochondria is not working properly there isn't an appropriate organelle function ( option B).
Option D is correct because ATP is needed for the membrane proteins to undergo active transport. For example the sodium-potassium pump is crucial for the balance of ions. With no energy the protein involved in this process would not work.
<span>Jane's observation will be that in the transparent bottle, the algae and small plants present in the pond water release oxygen during photosynthesis, while in the dark bottle, photosynthesis doesn’t occur due to darkness. Therefore, oxygen in the transparent bottle is more than that in the dark bottle. In photosynthesis, photosynthesizing organisms, such are algae and small plants, use carbon dioxide and water and convert it into glucose and oxygen in the present of sunlight. Therefore, organisms in the transparent bottle can perform photosynthesis and consequently release oxygen. However, this is not the case with the dark bottle that cannot transmit the sunlight.</span>
(hi, i dont know about this one personally, but i found an answer somewhere else on the internet thatll hopefully help u)
Answer: They consist of long chains of C, H, and O.
Explanation:
In terms of chemical composition, lipids differ from nucleic acids and proteins because they mostly just contain carbon, hydrogen, and oxygen (except for phospholipids which of course contain phosphorous). In addition to those elements, proteins contain nitrogen and sulfur, and nucleic acids contain nitrogen and phosphorous.
Carbohydrates share the C, H, and O composition as lipids, but they differ in structure. Lipids are generally exist as triglycerides, which consist of a triple hydroxyl alcohol (glycerol) that has bonded to three long-chain carboxylic acids (fatty acids) in a triple condensation reaction. Carbohydrates on the other hand are made of carbon ring structures that either remain alone or polymerize into long polysaccharide chains.
<span>The space-filling model of a hydrogen molecule would be something like OO , two circles stuck to each other, even squished a little bit. The model for carbon dioxide would be like OOO, with the two circles on the sides a little bigger and squished into the middle circle. </span>
