Answer:

Los plasmodesmos forman una ruta importante para la comunicación entre las células vegetales. Regulan la comunicación de célula a célula, permitiendo así la diferenciación de órganos y tejidos vegetales.

Los plasmodesmos facilitan el movimiento de moléculas entre las células, desde pequeños productos fotosintéticos hasta grandes proteínas y ARNm. En el tejido vascular, los plasmodesmos son cruciales para el movimiento de nutrientes. También son cruciales durante el desarrollo porque, a diferencia de las células animales, las células vegetales no se mueven. Por tanto, la expresión correcta de genes tanto temporal como espacialmente es importante. Mientras que las células vegetales, como las células animales, son capaces de interactuar receptor-ligando para enviar señales a otras células, los plasmodesmos ofrecen contacto directo. Además, el tamaño de la manga difiere en diferentes tipos de células y tejidos vegetales. Por tanto, los plasmodesmos son un componente celular activo en el transporte intercelular, durante el desarrollo y en el tejido maduro.

Answer:

see below

Explanation:

amplification: MUTATION = a type of mutation

independent assortment: MENDELIAN = how different

genes independently separate from one another

when reproductive cells develop

nondisjunction: MUTATION = a type of chromosomal

mutation

translocation: MUTATION = another type of chromosomal

mutation

codominance: MENDELIAN = a relationship between two

genes where neither allele is recessive and both

are expressed

insertion: MUTATION = a type of mutation

radiation: MUTATION = causes mutations

virus: MUTATION = causes mutations as the virus

replicates

deletion: MUTATION = a type of mutation

law of dominance: MENDELIAN = one of Mendel's laws

of inheritance

sex linked traits: MENDELIAN = linkage is an exception

to Mendel's law of independent assortment

incomplete dominance: MENDELIAN = when none of the

factors of a gene is dominant and there is a blend,

such as a red flower crossed with a white flower

turns out pink

law of segregation: MENDELIAN = one of Mendel's laws

of inheritance

substitution: MUTATION = a type of mutation

When light is refracted, the degree of bending is determined in part by?

EastWind [94]

<span>Refraction happens when there</span> is a bending of path of a light wave as it passes across the boundary separating two media and the degree of bending is determined in part by the total change in velocity as the light<span> passes from one medium to the other. In addition, the change in speed experienced by a wave when it changes medium can result in a number of beautiful optical effects. </span>

You have to choose between playing a team sport and taking music lessons because the practices overlap. what economic concept do

trapecia [35]

Time is scare is the economic concept this dilemma demonstrate.

<h3>Why Time is scare?</h3>

The time is scare because there is an over lap between the team sport or doing the music instruction. This demonstrates that there is not enough time to meet demand.

Two of the tasks require more time than is available. Both team sports and music courses cannot be played because of the lack of time.

Although there is a strong need for time, two things cannot happen at once. The need for time is great, but there is nothing one can do about it; she must choose between the two options presented.

A solution that contains more solute than it would normally hold at that temperature is said to be

Vitek1552 [10]

Answer: supersaturated

Explanation: A supersaturated solution is a solution in which the dissolved solute is more than the solvent can hold at that particular temperature.

A solution is a substance which sontains a dissolved solute. A solution can be saturated, unsaturated or supersaturated.

A saturated solution contains the maximum amount of dissolved solute a solvent can hold at that temperature.

An unsaturated solution contains less amount of solute than the solvent can hold at that temperature, this means that more solute can still dissolve in the solution.

A supersaturated solution contains more solute that can be dissolved in the solvent at that temperature.

When you open the door to your house on a cold day, you feel a cold draft. What causes

wariber [46]

Answer:

4. Warm air from the inside moving toward the cold air outside.

Explanation:

A cold draft can be defined as the process in which a current of cold air is being drawn in from the outside. Also, it involves the process in which a current of warm inside air exits or leaves a building through an opening.

This ultimately implies that, when you open the door to your house on a cold day, you would feel a cold draft as a result of the movement between the warm air from the inside moving toward the cold air outside. The warm air that were trapped inside your house would escape through the door due to a difference between the outside (cold) and inside (warm) atmospheric pressure.

Hence, a difference in temperature and atmospheric pressure between the outside and inside air usually causes a cold draft.

<em>Additionally, air typically moves or travels from a region of high pressure to a region of lower pressure. </em>
