An underground water supply has a depth of 200 m of water. Water seeps in at the rate of 4 cm / year . Water is pumped out at the rate of 1m / year . How long will this water supply last? To find the net water loss from an underground water supply, subtract the amount that seeps into the water sup ply from the amount removed from the water supply. How long will the water supply last if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year ?
Answer:
208 years.
Explanation:
The water supply last for 208 years if the water seeps in at the rate of 4 cm / year and water is pumped out at the rate of 1m / year. The water supply last forever if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year because the same amount of water enters the underground which can be pumped from the soil. If more water is extracted from the soil as compared to it seeps, so with the passage of time water concentration in the soil decreases and in the last it disappeared.

Identify which of the following will easily pass through the membrane? A.) Protein Hormone B.) Steroid Hormone C.) Charged Ion D.) Water
Answer:
Hope this helps a bit, sorry if it doesn't. Have a good day/night! :}
Explanation:
Steroid Hormone: It is thought that, because of their lipophilic nature, free steroid hormones enter target cells primarily by passive diffusion through the cell membrane. After gaining entry to the cell, steroid hormones act as ligands for nuclear receptors and alter gene transcription
Protein Hormone: Small uncharged molecules can diffuse freely through a phospholipid bilayer. However, the bilayer is impermeable to larger polar molecules (such as glucose and amino acids) and to ions. These molecules pass across membranes via the action of specific transmembrane proteins, which act as transporters.
Water/Ion: Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
A substance that will easily pass through the membrane is: B. steroid hormone.
What is a membrane?A membrane can be defined as the thin layer that separates the ineterior of a living cell from another, especially by forming its outer boundary or layers.
This ultimaetly implies that, a membrane provides protection for a living cell or an internal cell compartment from its environment.
In conclusion, a steroid hormone is a substance that will easily pass through the membrane.

True or False? Plants are key in the Carbon Cycle. Plants take in O2 and release CO2 into the Atmosphere.
Answer:
FALSE

They are key in carbon cycle, because CO2 an breathe out 02 ,while humans do the reverse of what they do
What would happen if the American bullfrog went extinct? NO LINKS!!!!!!!!!!!!!!!!!!
Answer: The death of frogs would send a ripple through the ecosystem. The number of animals that eat the frogs will die off, then the animals that eat them will go hungry, and their populations will be devastated as well. This would just keep going up the food chain
Explanation:
Invasive bullfrogs upset the balance of predator-prey interactions and competition for food and shelter, but they also may be worsening another ecological disaster in the amphibian world. ... The invasive American Bullfrog can act as a vector, harboring this fungus, with no ill effects, and spread it to other amphibians
hopefully this helps :)
¿Qué estructuras y organelas son exclusivas de las células eucariotas vegetales?, ¿cuáles son las funciones de cada una?
Answer:
Las estructuras y organelas que son exclusivas de las células eucariotas vegetales son: la pared celular, los cloroplastos, las vacuolas y los plastidios. Cada una de estas estructuras tiene distintas funciones.
Explanation:
Las células eucariotas vegetales tienen otro tipo de estructuras y organelas ya que tienen otro tipo de procesos, entre los cuales se encuentra la fotosíntesis.
Funciones:
Pared Celular: protege la membrana plasmática y toda la estructura celular. Tiene plasmodesmos a través de los cuales ingresan sustancias.
Vacuolas: almacenan sales, agua y productos residuales
Plastidios: le dan distintas características a las plantas. Algunos almacenan sustancias, otros definen su color.
Cloroplastos: son un tipo de plastidios y tienen un pigmento llamado clorofila.

Explanation:
a population of animals is split in half by a river before speciation is completed the two halves are rejoined when a drought causes the river to run dry how would this impact the two populations
A. speciation would still occur because the two halves would be too different genetically to interbreed.
B. traits that had developed through mutation would still exist only in one of the halves.
C. the two halves would be reproductively isolated.
D. individuals could now freely mate, and gene flow would increase. (this took so long to write please clap)
Answer:
D. Individuals could now freely mate, and gene flow would increase.
Explanation:
Since genes/traits are passed on from parent to offspring the gene flow would definitely increase. Since the population of animals is now brought back together by the drought, they now have more mates resulting in more and different genes combining. Therefore, the gene flow would increase.

pollination is an external process. why?
Answer:
It requires agents to carry the pollen anther to stigma.
Explanation:
Why is it important for a cell to be able to turn a gene off?
Answer:
Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.

process of how a seed grows into a plant
Answer: As it takes up more water, the seed expands and the seed coat cracks open. The embryo inside the seed is made up of a small shoot and a small root. The root is the first to emerge from the seed. As it grows, it anchors the plant to the ground, and begins absorbing water through the root.
