Which direction does Xylem flow? Phloem?

Biology
1 answer:
PIT_PIT [208]3 years ago
4 0

Answer:

The movement of Xylem is unidirectional and phloem is bidirectional

Explanation:

The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.

Phloem transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure. ... Hence the water flows from regions of high turgor pressure to low turgor pressure and the direction can be upwards or downwards from the leaves based on the gradient.

During which process is ethanol produced?
Kipish [7]

Answer:

Alcohol fermentation

Explanation:

When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration

One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.

Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture

This process is taken advantage of to brew beer and wine.

pashok25 [27]

Answer:

The correct option is lamprey.

Explanation:

Lamprey is a kind of fish which lack jaws. They lack a true skeleton, but the cartilage is present in them. Due to lack of proper backbone, they look similar to snails. The lamprey reproduces by laying eggs in the water. Larvae tend to develop from these eggs. The lamprey releases its eggs only in freshwater. Only the mature lamprey live in the sea to act as a parasite and take food. For laying eggs, it travels to freshwater.
