Why does osmosis not cause submerged water plants to swell up and burst?

The number of cells in an average-sized adult human is on the order of 10^14 cells. Use this information, and the estimate that

KengaRu [80]

IF:
Number of cells: $C = 10^{14}$
DNA lenght: $D = 2m = 12.42 * 10^{-4} mi$
Distance from Earth to Sun: $ES=93000000 mi = 9.3* 10^{7}mi$

Then:
a) Over how many miles would the total DNA from the average human stretch?
The answer is product of multiplication of the number of cells (C) and the DNA length (D):
Total DNA: $T = C*D$
⇒ $T = 10^{14}*12.42* 10^{-4} mi$
⇒ $T = 12.42* 10^{14-4} mi$
⇒ $T = 12.42* 10^{10} mi$
The total DNA from the average human will stretch $12.42* 10^{10} mi$

b) How many times would the total DNA from the average human stretch from Earth to the Sun and back?
The answer is concluded from the ratio of the total DNA length (T) and the twice (because of stretch to the Sun and back, thus, two directions) of distance from Earth to the Sun (ES) and :
Ratio: $R= \frac{T}{2*ES}$
⇒ $R = \frac{12.42* 10^{10}mi }{2*(9.3* 10^{7}mi)}$
⇒ $R = \frac{12.42* 10^{10}}{18.6*10^{7}}$
⇒ $R = 0.6677* 10^{10-7}$
 ⇒ $R = 0.6677* 10^{3}$
 ⇒ [tex]R = 667.7
Thus, 667,7 times will the total DNA from the average human stretch from Earth to the Sun and back.

GUANINE

Adenine always bonds with thymine, and cytosine always bonds with guanine.

In flowering plants, plasmodesmata are narrow channels through cell walls that connect the cytoplasms of adjacent cells. AN expl

The plant cells communicate across cell walls through Plasmodesmata.

how do plant cells communicate across cell walls?

Between tiny channels woven through the walls of neighboring plant cells, plant cells can communicate with one another through channels referred to as plasmodesmata.
These channels enable chemicals to move freely between cells, allowing plants to grow regularly and form tissues and organs.
However, plasmodesmata also act as entryways that viruses can employ to infect an increasing number of cells.
Given these advantages and disadvantages, plants must balance the permeability of their plasmodesmata in order to move materials from one cell to another while preventing the spread of infection.

An adolescent is brought to the ambulatory care clinic after being hit in the eye during a sporting event. There is no serious d

Tatiana [17]

<h2>Simple contusion </h2>

Explanation:

Simple contusion in eye

Simple contusion is also known as bruise or commonly known as black eye which is used to describe the discoloration that occurs around an eye after a trauma to the eye or surrounding tissues
It is caused by broken blood vessels under the surface of the skin is typically accompanied by swelling
A serious condition that can accompany a black eye is bleeding inside the eye, in the space between the back side of the cornea and the front of the iris which is called hyphema

Scleral hemorrhage

Scleral hemorrhage also known as subconjunctival hemorrhage
When small and delicate blood vessels break beneath the tissue covering the white of the eye (conjunctiva), resulting eye redness then this condition is known as subconjunctival hemorrhage
A subconjunctival hemorrhage usually is benign, causing no vision problems or significant eye discomfort despite its conspicuous appearance
But eye redness also can be a sign of other types of potentially serious eye conditions

How does the use of nonrenewable resources compare to the use of renewable resources?

Afina-wow [57]

Renewable resources as u can guess are resources which can be reused. for example, wind energy and hydropower.

however non renewable resources are things like coal which can only be used once
