Which of the following is the largest particle in soil? A-clay B-sand C-silt D-humus

Biology
1 answer:
Akimi4 [234]3 years ago
7 0

Well the soil classification is usually done on the basis of particle sizes and composition of soil.

<span>Clay </span>usually consists of particles less than 0.075 mm in size. It is a sticky soil and shows great changes in volume with variation in its water contact. It also shows considerable strength when air dried.

<span>Silt </span>has larger particles than clay and are mainly inorganic in nature. The particle size is less than 0.075mm and exhibits slightly plastic or non plastic behaviour.

Humus is soil consisting of dead and decaying organic matter. It is mainly organic in content but some inorganic particles may be mixed in it. The top soil in a tropical forest may be considered as humus.

Describe how the complete oxidation of 1 mole of glucose can generate 32 ATPs. You should include i) products of anaerobic glyco
inn [45]

Answer:

Explanation:

1.During glycolysis,four molecules of ATP are formed,and two are expended to cause the initial phosphorylation of glucose to get the process going.This gives a net gain of two molecules of ATP

For every glucose molecule that undergoes cellular respiration, the citric acid cycle is carried out twice; this is because glycolysis (the first stage of aerobic respiration) produces two pyruvate molecules per glucose molecule. During pyruvate oxidation (the second stage of aerobic respiration), each pyruvate molecule is converted into one molecule of acetyl-CoA—the input into the citric acid cycle. Therefore, for every glucose molecule, two acetyl-CoA molecules are produced. Each of the two acetyl-CoA molecules goes once through the citric acid cycle.

The citric acid cycle begins with the fusion of acetyl-CoA and oxaloacetate to form citric acid. For each acetyl-CoA molecule, the products of the citric acid cycle are two carbon dioxide molecules, three NADH molecules, one FADH2 molecule, and one GTP/ATP molecule. Therefore, for every glucose molecule (which generates two acetyl-CoA molecules), the citric acid cycle yields four carbon dioxide molecules, six NADH molecules, two FADH2 molecules, and two GTP/ATP molecules. The citric acid cycle also regenerates oxaloacetate, the molecule that starts the cycle.

While the ATP yield of the citric acid cycle is modest, the generation of coenzymes NADH and FADH2 is critical for ATP production in the final stage of cellular respiration, oxidative phosphorylation. These coenzymes act as electron carriers and donate their electrons to the electron transport chain, ultimately driving the production of most of the ATP produced by cellular respiration.

Drag each tile to the correct location on the table.
RideAnS [48]

Answer:

Kidneys : helps in forming urine

Ureter : They are connected to kidney and by peristaltic action transports urine from kidneys to bladder .

Urinary bladder : It is an hollow sac that holds the urine .

Urethra : transports urine from the bladder to outside of the body .

Explanation:

The human excretory system consists of   : Kidney ,ureter ,urinary bladder and urethra .The figure is shown below .

Now , as far as functions are concerned we have :

Kidneys : They have excretory units called nephrons that  further  consist of :

  • Bowman's capsule
  • PCT (Proximal convoluted tubule )
  • DCT (Distal convoluted tubule)
  • CT (collecting tubule )

In nephrons urine is formed and via ureter it is transported to a hollow sac like structure called  urinary bladder .

This bladder has muscles that cant remain contracted up to longer period )and then voluntary and involuntary it is excreted through urethra .

The process of passing urine is called Micturition .
