the most often the start of a scientific investigation. is observation
The answer is lipids.
<span>The macromolecules with the highest number of carbon-hydrogen (C-H) bonds are the lipids. The one of the main functions of the lipids is energy storage, therefore, they contain many C-H bonds which contain potential energy. Although carbohydrates can also store energy, they contain much oxygen .
So, he will need mostly black and red balls for a model of lipids.</span>
Answer:
Plants use cellular respiration to harvest the energy stored in the molecules
Explanation:
Plants, just like any other living organisms, need energy to power their cellular processes. Therefore plants also perform cellular respiration by burning energy molecules like glucose. The difference with plants, unlike animals, is that they make their own glucose from abiotic factors like sunlight and carbon dioxide. They do this through the process of photosynthesis. Animals have to consume ready-made glucose that emanated (directly or indirectly)from plants.
Answer:
The nuclear pore complex is a huge structure composed of about 30 different pore proteins, and its central channel has a diameter of approximately 10-40 nm, which is large enough for even very large protein complexes. For this reason, it is unnecessary to unfold the protein, which can pass through the pore in its native state.
Explanation:
- Protein transport into the endoplasmic reticulum (ER) or mitochondria requires unfolding of the protein and threading the amino acid chain through a channel or pore into the organelle.
- In contrast, protein transport into the nucleus does not require unfolding of the protein.
- This is because, nuclear pore complex is a huge structure composed of about 30 different pore proteins, and its central channel has a diameter of approximately 10-40 nm, which is large enough for even very large protein complexes. For this reason, it is unnecessary to unfold the protein, which can pass through the pore in its native state.
Answer:
Explanation:
Hot tubs are vulnerable to contamination because of there high temperature and open-top body which makes it a good environment for some bacteria (such as Legionella) to grow.
The addition of chlorine to a hot-tub does not fix this issue because chlorine (and other common disinfectant) easily breakdown in high water temperature and thus cannot operate at the high temperature of the hot tubs.
