Answer:500
Explanation:density=mass/volume.
Just substitute 50 and 10 in your equations and you’ll get your answer (mass).
50=m/10
(10)50= m/10 (10)
500=mass
The soil quality will most likely increase. There is a significant correlation between carbon emission and soil quality, as it has been proved that when one increase, the other those that too, because of the multiple beneficial effects that minor carbon emission have on the whole eco system. Those benefit can be different but the result will be almost the same.
Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
<u>Aerobic Respiration</u>
- Occurs in the presence of free oxygen.
- Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
- Respiration occurs in the mitochondria.
- Takes place in two steps or stages: Krebs cycle and electron transporter chain.
- Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
<u>Anaerobic Respiration </u>
- Occurs in the absence of free oxygen
- Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
- There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
- Lactic fermentation produces lactic acid and 2 ATP
- Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
- The whole anaerobic process occurs outside the mitochondria.
Answer and Explanation:
12. The water has a lower osmotic pressure than the cell sap of the root hairs. Due to the osmotic difference water is drawn by osmosis across the cell wall and cell membrane into root hairs. Water moves by osmosis into adjacent cortex cells and their osmotic pressure is lowered drawing water by osmosis. Water passes to the successive cortex cells and through the endodermis to the xylem vessels. At the leaves, the xylem passes into the petiole and then into the veins of the leaf. Water leaves the veins and enters the cells of the spongy and palisade layers.
13. Food and other manufactured material are translocated by the phloem. They enter the sieve elements through plasmodesmata connecting them to adjacent companion cells which are sites of high metabolic activity. The manufactured food are translocated through sieve tube along the cytoplasmic strands.
