Why is the elimination of feaces not an excretory process?
Answer:
Feaces is a product of egestion. It is not directly formed from the major organs responsible for excretion (liver, kidneys, lungs and skin) and hence is not a result of metabolic reactions. That is why, feaces are not an excretory product.

Which of the following would be the best definition of diffusion? The movement of molecules....
- from an area of higher concentration to an area of lower concentration
-using energy
-down the concentration gradient
-from an area of lower concentration to an area of higher concentration
-using energy
-up a concentration gradient
-from an area of low concentration to an area of high concentration
- without energy
- up the concentration gradient
-from an area of higher concentration to an area of lower concentration
-without energy
-down the concentration gradient
Answer:
-from an area of higher concentration to an area of lower concentration
-without energy
-down the concentration gradient
Explanation:
Simple diffusion does not require energy. This is likely what the question is referring to.
An example of simple diffusion:
If you blow up a balloon and then poke a small hole in it. The air will leak out from the high concentration inside the balloon to the low concentration outside of the balloon. It does not require any energy to be put it--it leaks out on its own as long as there is a hole.
Answer:
-from an area of low concentration to an area of high concentration
- without energy
- down the concentration gradient
Explanation:
The movement of molecules from an area of low concentration to an area of high concentration, without energy, down the concentration gradient is correct.

the managed consumption of natural resources to prevent their depletion or environmental destruction
the deployment of fossil fuels to environments that previously did not have access to such resources
ways in which individuals are able to conserve native animal and plant species
Answer:
B.
Explanation:
Sustainable practices are all about the managed consumption of natural resources to prevent their depletion or environmental destruction.
What is sustainability?It refers to the management of resources in such a way that their depletion is prevented and the environment is conserved in the process.
Sustainable practices include actions targeted at conserving resources to prevent abusive or wanton use and ensure that the future heritage is intact.
For example, cutting down trees for construction and following it up with the planting of other trees is a sustainable practice. By doing so, trees will not get depleted in the forest.

what happens if plant protoplasts are placed in distilled water
Answer:
Protoplasts are plant cells that have had their cell walls removed. What happens if plant protoplasts are placed in distilled water? A They get larger and become turgid.When the plant protoplast is placed in distilled water ; It becomes Turgid
When protoplast is placed in a distilled water, the distilled water flows into the protoplast and this makes the protoplast to become turgid and this is due to absence of the plants cell wall and also the difference in the concentration of the contents of the protoplast and the distilled water. Protoplast represents the plant cell without the presence of the cell wall.
Hence we can conclude that when the plant protoplast is placed in distilled water it becomes Turgid.

Barrera que delimita a la celula y que contiene sus organelos y los productos generados dentro de la misma , a traves de ella entran nutrientes y expulsan desechos
Answer:
Membrana celular
Explanation:
La membrana plasmática o membrana celular, presente en todas la céluas, la protege y encierra a distintas organelas, que al estar aisladas deñexterior, funcionan como una unidad difereciada. Aun asi, cada célula mantiene comunicación con otras células a partir de esta membrana. Esta estructura, a parte, permite el paso de sustancias desde y hacia el iterior celular. Moleculas necesarias para el adecuado funcionamiento de la celula ingresan a la misma, mientras que otras destinadas a exportación, desechos, mentenimiento del equilibrio, etc, salen al espacio intercelular. Las membranas biológicas estan formadas por una bicapa lipídica. los lípidos se posicionan de manera tal que las cabezas hidrofilicas apuntan hacia el exterio e interior celular, mientras que las colas hidrofóbicas se disponen hacia el interior de la bicapa. Las membranas celulares son fluidas, es decir que las moleculas que la componen tienen la capacidad de moverse.
Dentro de la célula, e incluidas en el citoplasma, hay varias organelas que también se encuentran delimitadas por membrana, tales como nucleo, reticulo endoplasmático, aparato de golgi, mitocondrias, cloroplastos, vacuolas y vesiculas. El contenido de estas organelas se encuentra aislado del citoplasma gracias a la contención de la membra.

2. From the fossil evidence shown, how did the forefeet change over time?
3. From the fossil evidence shown, how did the skills change over time?
4. How might the environment in which each of these species lived have affected the evolution of horses?
Answer:
1: 50 million years
2: The forefeet changed over time by the bones merging into one to create the hoofed feet that we are used to today.
3: Their teeth and skull changed over time to better fit the environment and food they fed on. Their feet and hight changed based on the physical requirements of the environment like walking across dense forests vs open prairies and how they had to move to access food.
4: The environment affected the way the horses evolved because they had to evolve to better fit and survive/thrive the new environments they lived in.

invasive species lack natural predators and take resources away from native species
invasive species release toxins into the environment
invasive species cannot adapt to their new environment
invasive species like to proliferate (reproduce)

1. How are seasons connected to the annual CO2 cycle?
CO2 in the atmosphere decreases during the growing season and increases during the rest of the year, which leads to maximum buildup in April and May before photosynthesis begins to take over again.
There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.

Give any 2 significance of nitrogen cycle to green plant
Nitrogen is the most abundant element in our planet’s atmosphere. Approximately 78% of the atmosphere is made up of nitrogen gas (N2).
Plant uptake of nitrogen compounds
Once nitrogen is converted into compounds like ammonium and nitrate, these can be taken up from soils by plants and then the nitrogen can be used to form macromolecules like proteins and nucleic acids.
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
As part of these life processes, nitrogen is transformed from one chemical form to another. The transformations that nitrogen undergoes as it moves between the atmosphere, the land and living things make up the nitrogen cycle.
Fixation
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:

Las plantas transforman la luz del sol a través de unas células llamadas: a) Estomas. b) Cloroplastos. c) Raíces. d)Clorofila.
Respuesta:
La respuesta correcta es: b) Cloroplastos.
Explicación:
Los cloroplastos son organelas que se encuentran en las células vegetales y son responsables de realizar el proceso clave para la supervivencia de estos seres vivos: la fotosíntesis.
La fotosíntesis consiste en la transformación de sustancias inorgánicas a materia orgánica gracias a la energía proveniente de la luz solar. Esta materia orgánica será utilizada para la producción de los nutrientes requeridos por las células de la planta.
Los cloroplastos constan de una envoltura conformada por dos membranas y por unas vesículas llamadas tilacoides donde se encuentran las moléculas que participan en la transformación de energía lumínica a energía química que ocurre durante la fotosíntesis, por ejemplo la clorofila (que es un pigmento verde que le da a la planta su característico color).
