The immediate source of the intracellular fluid surrounding all human body cells is capillaries.

Interstitial fluid forms the immediate environment of all cells.

What are capillaries?

Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.
They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.
Capillaries are delicate blood vessels that exist throughout your body.
They transport blood, nutrients and oxygen to cells in your organs and body systems.
Capillaries are the smallest blood vessels in your vascular system.

In 3-5 sentences, construct an argument for why more cities should incorporate green roofs. (4 points)

expeople1 [14]

Green roof do have several advantages over ordinary roofs as follows.

<h3><u>Explanation:</u></h3>

Green roof are defined as the roof over which a thin layer of soil is placed to grow a thin layer of grass or other plants. This have several advantages as follows:

A. Green roof help in reducing water logging in roofs, thereby reducing the dampening of the concrete, and increasing the longevity of the roof.

B. It is actually energy saving, by reducing the summer temperatures by evaporation and transpiration. It also maintains a warm room temperature in winter by reducing the heat loss.

C. It's also actually low in budget. Its initial cost is more than ordinary roof, but the maintenance cost is very low, if not nill.

D. Its a place for recreational activities. Greenery in urban areas are very rare sight, which can be met through this project.

E. Green roofs provide a chance for urban agriculture.

Dos condiciones anormales en el hombre, que son las cataratas y la fragilidad de huesos son debidas a alelos dominantes. Un homb

SpyIntel [72]

Answer:

La probabilidad de:

a) Tener un hijo completamente normal, cchh = 25%

b) Que tenga cataratas y huesos normales C-hh = 25%

c) Que tenga ojos normales y huesos frágiles ccH- = 25%

d) Que padezca ambas enfermedades C-H- = 25%.

Explanation:

<u>Datos disponibles:</u>

Alelo dominante C expresa cataratas
Alelo recesivo c expresa visión normal
Alelo dominante H expresa fragilidad de huesos
Alelo recesivo h expresa huesos normales

Los posibles genotipos para cada característica entonces son:

CC y Cc ----> Cataratas
cc -------------> Ojos normales
HH y Hh ----> Huesos frágiles
hh--------------> Huesos normales

Sabiendo esto, podemos deducir los genotipos del hombre y la mujer involucrados en la cruza.

Hombre con cataratas y huesos normales, tiene genotipo C-hh
Padre del hombre tiene ojos normales, cc

El padre del hombre es homocigota recesivo, expresando ojos normales. Esto significa que solo pudo heredarle al hijo (el hombre) un alelo recesivo, c. Pero el hombre expresa cataratas, lo que significa que porta también un alelo dominante, probablemente heredado de la madre. Entonces el hombre es heterocigota para el tipo de ojos. Y puesto que tiene huesos normales, sabemos que es homocigota recesivo para esta característica.

Genotipo del Hombre: Cchh

Mujer sin cataratas y huesos frágiles, tiene genotipo ccH-
Padre de la mujer con huesos normales, hh

El padre de la mujer tiene huesos normales, implicando que su genotipo es homocigota recesivo y que solo puede heredarle a la progenie alelos recesivos. La mujer tiene huesos frágiles, lo que supone que heredó el alelo dominante de su madre. Puesto que recibió un alelo dominante de la madre y uno recesivo del padre, la mujer es entonces heterocigota para la característica en cuestión. Ella también tiene visión normal, lo que significa que su genotipo para esta característica es homocigota recesivo.

Genotipo de la mujer: ccHh

Sabiendo los genotipos de ambos integrantes de la pareja, podemos realizar la cruza:

Cruza: Hombre x Mujer

Parentales) Cchh x ccHh

Gametas) Ch, ch, Ch, ch (hombre)

cH, ch, cH, ch (mujer)

Cuadro de Punett)

Ch ch Ch ch

cH CcHh ccHh CcHh ccHh

ch Cchh cchh Cchh cchh

cH CcHh ccHh CcHh ccHh

ch Cchh cchh Cchh cchh

F1) Genotipos y Fenotipos:

4/16 = 1/4 = 25% CcHh, Cataratas y huesos frágiles
4/16 = 1/4 = 25% ccHh, Ojos normales y huesos frágiles
4/16 = 1/4 = 25% Cchh, Cataratas y huesos normales
4/16 = 14 = 25% cchh, ojos normales y huesos normales
