kolezko [41]

Answer:

  • Random dispersion occurs with dandelion and other plants that have wind-dispersed seeds that germinate wherever they happen to fall in a favorable environment.
  • Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.
  • Clumped dispersions may also result from habitat heterogeneity. If favorable conditions are localized, organisms will tend to clump around those, such as lions around a watering hole.

forsale [732]

Answer;

Cycilc AMP

Explanation;

-Second messengers are molecules that relay signals received at receptors on the cell surface; such as the arrival of protein hormones, growth factors, etc., to target molecules in the cytosol and/or nucleus.

-Many of the chemical messengers such as hormones, that transmit messages from one cell to another never enter the target cell, these molecules are known as first messengers which work by binding to a specific receptor on the cell surface. The receptor then stimulates or inhibits the production of a so-called second messenger within the cell.

-The second messenger are small molecules such as Cyclic AMP, which activate an effector within a cell.

r-ruslan [8.4K]

Answer:

I would expect to see 3 bands after completing DNA gel electriphoresis and staining the gel.

Explanation:

The restriction enzyme Hind3 has two Recognization sites in the 400 base pair long DNA molecule.

     As a result the restriction enzyme Hind3 with generate 2 cuts in the target 400 base pair long DNA molecule.

     The number of 2 cuts in the target DNA molecule will generate 3 DNA fragments.From this point of view it can be stated that 3 bands will form after completing DNA electrophoresis and staining the gel.
