plants cells would not not have been able to absorb these minerals ions from the pond by diffusion . explain why not
Answer:t hey cannot be absorbed by diffusion , because the minerals are in very low concentration. Instead, active transport is used. ... Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.

Which of the following describes how metamorphic rock forms?
A
Tectonic plate boundaries break apart an existing parent rock.
B
An igneous rock deep in the Earth is exposed to hot material.
C
Molten rock solidifies and hardens on top of the Earth’s crust.
D
A parent rock is baked and melted into liquid rock in the Earth.
An igneous rock deep in the Earth is exposed to high heat, high pressure, and hot mineral-rich fluids, by this process metamorphic rock forms, hence option B is correct.
What is a metamorphic rock?Metamorphic rocks are produced when rocks are exposed to high heat, and pressure, hot mineral-rich fluids, or maybe some combination of these factors, all these conditions are found deep on Earth.
In the deep of Earth, if an igneous rock deep in the Earth is exposed to hot material, this result forms a metamorphic rock.
This is also a result when rocks change their original shape and identity due to high heat or pressure, this pressure is only found deeper in the Earth.
Therefore, if an igneous rock deep in the Earth is exposed to hot material, it results in metamorphic rock.

Name 3 characteristics of each physical state of matter.
Solid:
Liquid:
Gaseous:
Answer:
solid: Has a definite shape and volume. liquid: Has a definite volume, but take the shape of the container. gas: Has no definite shape or volume. change of state: When matter is converted from one of the three states (example: solid, liquid, or gas) to another state.
Explanation:
Answer:
Solid:
High Density
Definite mass, volume, and shape
Solids are incompressible and rigid
Liquid:
No definite shape (takes the shape of its container)
Has definite volume.
Particles are free to move over each other but are still attracted to each other.
Gaseous:
They are easy to compress
They expand to fill their containers
They occupy far more space than the liquids or solids from which they form

PLS HELP ASAP Select the word that means how easily water can move through a substance. Lesson 2.03 o particles permeability porosity
Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
The water can easily move through a substance and it is called permeability. Hence, option B is correct.
What is permeability?The ability of molecules to pass through a biological membrane or barrier is known as biological permeability. Because cell membranes are selectively impermeable, substances cannot pass through the barrier without consideration. Some of the characteristics that affect permeability include polarity, hydrophobicity, charge, size, and shape.
The metabolic activities, survival, and potential use of the cell in both biotechnological applications and physiological systems are all greatly impacted by the cell membrane permeability, which controls the rate of solute transport into and out of the cell.
The water can easily move through a substance when the substance is permeable. Hence, option B is correct.

El factor Rh- (r) en humanos es una característica que se hereda como un factor recesivo. Determine el genotipo de los parentales de las siguientes familias: - 1er caso: Dos padres con RH+ (R) tienen 5 hijos de los cuales 1 presenta el factor Rh- . - 2do caso: Un padre con factor RH+ y una madre con factor Rhtienen 6 niños de los cuales 3 son RH+ y 3 son Rh- - 3er caso: Un padre con factor RH+ y una madre que presenta un factor Rh- tienen 6 niños de los cuales son todos RH+ . Compruebe los resultados en cada caso. Ayúdenme porfa, estoy desesperada
Answer:
Caso: Ambos padres heterocigostos, Rr (Rh+)Caso: Padre heterocigoto Rr (Rh+). Madre homocigota recesiva rr (Rh-)Caso: Padre homocigoto dominante RR (Eh+). Madre homocigota recesiva rr (Rh-)Explanation:
El factor Rh+ es expresado por un alelo dominante que llamaremos R (Genotipo RR o Rr)El factor Rh- es expresado por un alelo recesivo que llamaremos r (Genotipo rr)1er caso: Dos padres con RH+ (R) tienen 5 hijos de los cuales 1 presenta el factor Rh-
si al menos uno de los hijos presenta el factor Rh-, entonces debe haber recibido un alelo recesivo r de cada padre. Por tanto los padres deben ser heterocigotos para el tipo de sangre Rh.

F1) 3/4 =75% de la progenie es Rh+ (RR o Rr)
1/4 = 25% de la progenie es Rh- (rr)
2do Caso: Un padre con factor RH+ y una madre con factor Rh- tienen 6 niños de los cuales 3 son RH+ y 3 son Rh-
Entre los hijos de esta pareja hay algunos que muestran Rh+ y Rh-.
Si la madre es Rh-, entonces su genotipo es rr y solo tiene alelos recesivos r para pasar a la progenie.
Sabemos que el padre es Rh+, lo que indica que en su genotipo hay al menos un alelo dominante R. Puesto que la mitad de sus hijos tiene factor Rh-, podemos asumir que el hombre es heterocigoto para el tipo de sangre (Rr). De los contrario, de ser homocigoto dominante, toda la descendencia seria Rh+. El padre le hereda a la mitad de los hijos el alelo R y a la otra mitad el alelo r.

3er caso: Un padre con factor RH+ y una madre que presenta un factor Rh- tienen 6 niños de los cuales son todos RH+
Si la madre es Rh- su genortipo es rr y solo puede heredarle a los hijos alelos recesivos, r.
El padre es Rh+, con lo que inferimos que el genotipo tiene al menos un alelo dominante R. Puesto que todos los hijos de esta pareja son Rh+, podriamos suponer que el padre es homocigoto para el tipo de sangre Rh+, heredandole a los hijos solo alelos dominantes.
