If you collected a piece of cell coating found directly external to a eukaryotic plasma membrane, and chemical tests showed that

it was made of cellulose, you would expect to see plasmodesmata if observed with an electron microscope.

Answer:

True.The cellulose must have been conveyed to the surface by the plasmodesmata through  contraction and relaxation of plasmodesmata  openings  for  movements of substances in and out of the cells.

Explanation:

Plasmodesmata are tiny cylindrical channels;  which pass through both the secondary and primary  cell walls of plant. They  are  lined by plasma membranes in plant cells; they are living passages .They connect  the cytoplasm of adjacent cells to one another, to form a continuous network for transport of certain substances across cells; aiding  effective cell communication.

<u>Structurally, they are produced in plant cells  when fragments  of the Endoplasmic Reticum  of the parents cells get trapped in the cell wall meant for formation of  new daughter cells during cell division.</u>

Answer:

True

Explanation:

The observed cell is a plant cell because of presence of cellulose coating on cell membrane. The plasmodesmata are the a layer between cell and cell membrane of plant cells that is porous in nature and enables communication between cell and outside environment. It is obvious to find this with cellulose coating. These plasmodesmatas have same function as gap junction animal cells.

Pacific nw tree octopus where does it live
ella [17]

The correct answer is - temperate rainforests of the Olympic Peninsula.

The Pacific northwest tree octopus is a fictional animal, thus it does not exist in the present, nor there is any proof that such a creature existed in the past, though there's every chance that it can evolve in the future.

According to the description of this fictional octopus species, unlike the octopuses we know, it is actually amphibious. This basically means that this octopus is able to live in the water, but also be terrestrial. It has developed from the octopuses in the East Pacific, and it started mostly to live on land, or rather on trees. It has used its eight tentacles in order to be able to have a perfect tool and easy arboreal life, swinging from one branch to another, being able to cover longer distances very easily, and manage to hunt with relative ease.

Which of the following is not a possible effect of increasing carbon dioxide levels in the atmosphere? a. increase in water cont
dolphi86 [110]

Answer:

C. Cutting down forests.

Explanation:

Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.

The effects of an increase in CO2 concentration in the atmosphere is as follows:

- increase in water contamination and floods

- ocean acidification

- reduction of cold-related deaths

However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.

When blood volume increases to the point that cardiac cells are stretched, the heart releases what natriuretic hormone?
Yuri [45]
The answer to this question would be: Brain Natriuretic Peptide(BNP) and or Atrial Natriuretic Peptide(ANP)

Both BNP and ANP can be found in heart tissue. But BNP is more frequently used because its level is higher, thus the laboratory result could be better. Both BNP and ANP has diuretic, natriuretic and antihypertensive effect that can counter the fluid overload in congestive heart failure. That is why they are secreted when the cells are stretched.
