B. heating a old home
In my opinion let’s just say if you have a old house and it starts getting very dusty. It would require more work to try fixing the heater.
It kind of depends.
<span>Spleen is also known as the graveyard of RBC, if it helps u
1.Stem cells in bone marrow make all blood cells. RBC lives about 120 days.
RBC are destroyed in Spleen. This process takes place as:
- RBCs are ruptured.
- Heme and globin portions separated.
- Globin > amino acids.
- Iron transferred in transferrin into the blood > into bone marrow for reuse.
- Heme > Biliverdin > Bilirubin > liver >small intestine.
2.Reticuloendothelial cells participate in the destruction of senescent RBC's. The spleen is a well suited site of RBC destruction given that cells must course through 2-3 micron apertures in the walls of splenic sinusoids, which is an ultimate test of cell pliability. Rigid cells are entrapped and phagocytosed. Intra-erythrocyte inclusions are removed during splenic circulation.
Destruction of RBCs happens within reticuloendothelial cells – NOT in the circulation. Globin and heme get recycled, porphyrin is degraded to bilirubin which is conjugated by the liver and excreted in the gut. Rate limiting step is conjugation. Indirect (unconjugated) bilirubin is result if this doesn’t happen.
Normally ~10% RBCs lyse while in circulation Þ Hgb gets released into circulation and rapidly disassociates into alpha and beta dimers which are bound by haptoglobin. The Hgb/haptoglobin complex is transported to the liver. If haptoglobin is depleted, free Hgb circulates and is filtered by the kidney. Free Hgb is either reabsorbed by renal tubular cells or excreted as free Hgb in the urine.
3. Another site reported that
RBC destroyed in liver and spleen, by macrophages. 2 million destroyed per second.
Hb is released and iron is recovered and returned to bone marrow.</span>
Seasonal changes in carbon dioxide concentration with the highest levels measured in May and the lowest levels measured in October will affect the photosynthesis rate due it is a reactant which is required during photosynthesis.
<h3>What are the photosynthetic chemical reactants?</h3>
Photosynthetic chemical reactants are those materials required to carry out photosynthetic reactions which include carbon dioxide and water molecules. These materials are used to generate simple carbohydrates such as glucose and oxygen.
Photosynthesis also requires sunlight to excite the electrons of chlorophyll molecules in order to generate chemical energy (glucose)
Therefore, with this data, we can see that the photosynthetic chemical reactants include both carbon dioxide and water, thereby fluctuations in the levels of these materials will affect the photosynthesis rate and thus may lead to a decrease and or an increase in the amount of photosynthetic products (i.e. oxygen and also glucose).

In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.
Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a signal). It can also be encrypted for safe storage and communication.
Answer:
I'm pretty sure that it's A
