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.

What are the 3 main processes common between terrestrial and aquatic ecosystems?
Answer:
Three main processes that are common between these are that they both make food through photosynthesis, they both perform transpiration, and they both need sunlight in order to process chemical energy.
I really hope this helped and have a great day! :)
The process that are seen in both terrestrial and aquatic ecosystems are;
Transpiration process
Photosynthesis for food synthesis
Energy through sunlight.
An ecosystem can be regarded as geographic area which contains plant as well as animals with other organisms and weather and landscape and they all carried out different functions so that bubble of life is formed.Ecosystem could be terrestrial as well as aquatic ecosystems.An aquatic ecosystem can be regarded as types of ecosystem containing body of water. In contrast to terrestrial ecosystems that is associated to land, there are Communities of organisms that their dependent is on each other as well as the environment all live in aquatic ecosystems.Aquatic ecosystems could contains body of oceans as well as lakes rivers, and stream.Terrestrial ecosystem can be regarded as community of organisms that dominate land, as well as interactions that exist between biotic as well as abiotic components in a given area. Some of terrestrial ecosystems are tundra, taigas as well as temperate deciduous forests and tropical rainforests.Some of the processes that can be attributed to both terrestrial and aquatic ecosystems are;
Making of their food could be through photosynthesis, this is the process whereby plant makes their food through the energy from sunlight.Sunlight is required as a source to process energy. Transpiration can be regarded as process involving movement of water through a plant, this could also encompass the evaporation of this water from aerial parts which could be in the leaves as well as stems and flowers.Therefore, both terrestrial and aquatic ecosystems have some process in common.

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.

What is HIV?HIV stands for Human Immunodeficiency Virus which is defined as a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS which stands for acquired immunodeficiency syndrome. There is currently no effective cure, while once people have HIV, it remains with it for life.
HIV can spread through sexual contact, illicit injection drug use or sharing needles, contact with infected blood, or from mother to child during pregnancy, childbirth or breastfeeding. HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle.
So, the correct option is A.

True or False: Atmospheric nitrogen (N2 gas) is easily taken up and used by plants and animals.
Answer:
False
Explanation: im only in the 8th grade
A plant requires minerals and nutrients for its growth. There are two types of nutrients on the demand of requirements, These nutrients are as follows:-
Micronutrient MacronutrientPlants totally depend on nitrogen for their functioning but atmospheric nitrogen is poisonous to the plant.
Hence there are various microbes that convert the atmospheric nitrogen to its amides which are non-poisonous and easy to absorb.

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)

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.

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.

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.
