Answer:

Inherited characteristic.

Explanation:

When the offspring has a characteristic identical to parents and siblings, we call this characteristic inheritable.

Science explains this from the genes, responsible for encoding instructions that define the baby's traits. Like a lottery, the transmission of physical characteristics will depend on the combination of genes. There are more than 200 genes passed on from generation to generation. In this group, there are dominant, traits that manifest themselves more strongly, and recessive characteristics that do not manifest themselves.

Thus, it is possible to understand, for example, the predominance of the color of the father's brown eyes, compared to the mother's blue ones. If the brown color gene received from the father is the dominant one, the blue color will be "forgotten". In order to have blue eyes, given that the gene is recessive, it is necessary that not only the father, but the couple have the gene for blue eyes and that at the crossing this gene is captured from both.

Answer:

When an offspring's trait is identical to the parent and it's siblings, we say that it is a n inherited trait.

Explanation:

Inherited traits are when you get features from your parents which are passed on to your genes.

¿Cual de los siguientes solutos que pueden estar presentes en el liquido extracelular es transportado de acuerdo al modelo de me

kolezko [41]

Complete question:

¿Cual de los siguientes solutos que pueden estar presentes en el liquido extracelular es transportado de acuerdo al modelo de mecanismo propuesto en la ilustracion?

A) Etanol.

B) Calcio.

C) Glucosa.

D) Estrógeno.

E) Oxígeno.

Nota: La ilustración se encuentra como un archivo adjunto.

Answer:

Ión Calcio y Estrógeno son transportados por proteinas canal a traves de la membrana.

Explanation:

Durante el paso de sustancias al interior o exterior de la celula ocurren dos tipos de transportes. Transporte activo y pasivo. El primero requiere de energia ya que se produce en contra de un gradiente electroquímico. El segundo, por otra parte, no requiere de energía ya que sucede a favor del gradiente electroquimico.

El transporte activo es mediado por proteinas transportadoras que actúan como bombas transportadoras.

El transporte pasivo puede ocurrir por

difusión simple a traves de la bicapa lipídica (sin ningunaproteina que medie su paso),
difusión facilitada a traves de proteinas canales (estas proteinas tienen forma de poro hidrofílico y permiten el paso de sustancias de un lado al otro de la membrana celular sin sufrir modificaciones. Permiten el pasaje de iones actuando como canales ionicos y de hormonas o neurotransmisores),
o difusión facilitada a través de proteinas transportadoras o carriers (estas proteinas son altamente selectivas y sufren un cambio temporal en su conformación al hacer pasar una sustancia de un lado al otro de la membrana plasmatica).

La ilustración adjuntada muestra un ejemplo de proteina de canal facilitando el transporte de distintas sustancias.

A) Etanol. Transporte pasivo. Difusión simple a traves de la bicapa lipídica.

B) Ion Calcio, Ca²⁺. Transporte pasivo. Difusión facilitada a traves de proteina canal.

C) Glucosa. Transporte pasivo. Difusión facilitada a traves de proteina transportadora o carrier.

D) Estrógeno. Transporte pasivo. Difusión facilitada a traves de proteina canal.

E) Oxígeno. Transporte pasivo. Difusión simple a traves de la bicapa lipídica.

Which of the following does NOT affect the flow of groundwater through an aquifer ? a. porosity C. gradient b . chemical weather

creativ13 [48]

Answer:

b . chemical weathering

Explanation:

Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

2. Can the classification system change? If so, provide an example of a way it has changed in the past. (2 points)

Elis [28]

Yes, classification system is still evolving together with our knowledge.

But, before changing the name (e.g. of a species) it is important to collect and gather a wealth of information in order to support that change. Classification system is still evolving. The reasons for the changes are DNA analyzes. It is the new way for discovering relation between organisms and put them in the right context (classification used to be based on morphological characteristics).

Change in classification can be shown in an example of fungi. In the 90s fungi classification included only phyla Chytridiomycota and Zygomycota. Now theyhave been classified mainly on the basis of characteristics of their sexual reproductive structures. So, there are 7 phyla now: Microsporidia, Chytridiomycota, Blastocladiomycota, Neocallimastigomycota, Glomeromycota, Ascomycota, and Basidiomycota
