Plasmodesmata can change in number, and when dilated can provide a passageway macromolecules

Plasmodesmata are essential for the intercellular transfer of both big informational macromolecules like proteins and smaller signaling chemicals in plant cells.

  • Plasmodesmata are membrane-lined structures that offer a high-conductance, aqueous channel for the transportation of information in the form of chemicals and macromolecules, such as transcription factors, from cell to cell.
  • The intimate interaction of the plasma membrane with the endoplasmic reticulum results in the formation of plasmodesmata.
  • The degree to which a particular cell acts as an individual or as a component of the entire organism is determined by the distribution and unitary conductance of plasmodesmata as well as other positional variables that affect development.

How does the endocrine system affect the excretory system?
Pachacha [2.7K]

Answer:

The right answer is Option A. It filters the blood that is used by the excretory system.

Explanation:

The endocrine system has great affect on the excretory system. It gives massages to the excretory system. When the amount of water is exceed in the body, the endocrine system send massage to the excretory system to produce more urine. And when the body has less amount of water, the

endocrine system send massage to the excretory system to produce less urine.

Throw some loght on dichloroindophenol chemical and its function in photosynthesis
madam [21]

Answer:

Dichloroindophenol chemical act as electron acceptor in photosynthesis

Explanation:

DCPIP (2,6-dichlorophenol-indophenol) in general is a dye of blue color which reduces to become colorless and hence act as an electron acceptor in the light reactions of photosynthesis

It is used to measure the rate of photosynthesis, because its reduction leads to identification of reducing agent (Diphenylcarbazide) in plant  that is produced at the time of photosynthesis with in the chloroplasts.

How is a frog disected?
Stella [2.4K]
<span>Lay the frog on its back, spread out its limbs, and pin them to the tray. Use forceps to lift the skin between the hind legs and make a small incision with a scalpel. Continue the cut up the center of the frog's body with scissors, being careful to cut through the skin only. Use forceps to hold the skin away from the muscle while you cut, if necessary. Make horizontal incisions just above the legs and just below the arms, then fold the resulting flaps back and pin them. (You may need to use a scalpel to help separate the skin from the muscle underneath as you fold it back.)Repeat the incisions as before, this time cutting through the muscle layer to a point just below the arms. Lift the muscle with the forceps to prevent cutting the organs underneath.When you reach the area just below the arms, turn your scissors and make horizontal cuts through the hard sternum. Repeat the horizontal cuts just above the arms, and then remove the bony strips entirely. Pin the remaining muscle flaps back, just as with the skin.<span>Look into the body cavity. The yellow finger-like projections on the sides are the fat bodies. It may be necessary to remove some of these in order to see the organs clearly. Likewise, a female specimen may have well-developed eggs filling the body cavity and obscuring the organs. Remove them as necessary.</span></span>

Which phrase describes a density-independent limiting factor that can affect
Alenkasestr [34]

The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).

<h3>What is a density-independent limiting factor?</h3>

A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.

These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.

Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.

Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.
