How can planting a large area of just one variety of plant cause problems for both a farmer and an ecosystem?
Answers
Answer:
Particular plants use particular nutrients from the soil. If you were to consistently plant a large number of plants, of the same species, in the same area. The plant will use all of the nutrients it needs, before the nutrients are replenished. This can cause a decrease in the farmer's yield. By doing this you also create a habbitat for pests. Some pests live off to certain plants, so if your not planting other crops, the pests will thrive. Plating a variety of crops is good because some plants will repel pests from other crops that the pests may be attracted too.

A mutation is least likely to affect a cell when the mutation --
Answers
A mutation is least likely to affect a cell when the mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.
What is the function of cells and mutation?As genetic materials, nucleic acids encode information about the cell's structure and function, its proteins, receptors, and so on. The mRNA that is formed from the gene has roles in the formation of the receptor, the enzymes, etc., so if any mutation happens to the gene that is in the coding region, then it can show its impact, but if the mutation is of the silent type, then it has no impact on the cell.
Hence, when a mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.

A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and molluscs is removed from the oceanic food chain to become part of another, slower carbon reservoir.
Answers
Answer:
Crustaceans and Molluscs play an important role in the oceanic carbon sink.
Explanation:
Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.
CO2 is not combustible. creates carbonic acid in the oceans. Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)If helpful, please mark as brainliest! =)

Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.
Humans circulatory system is similar due to presence of artrium and ventricles and different to other animals due to number of heart chambers.
How human circulatory system similar and different to other animals?Humans have a heart with two atria and two ventricles that prevents bactward flow of blood. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle that can push blood in two directions.

En una isla oceánica aislada hay una especie de pájaros, la
mayoría de plumaje gris. Una variedad con manchas blancas
constituye el 4% de la población. Esta característica se debe a un
gene recesivo (s) al del plumaje de color gris entero (S).
¿En qué frecuencia se encuentra el gene s?
a 0.3
b 0.2
c 0.1
d 0.05
Answers
Answer:
La frecuencia del alelo recesivo s es igual a 0.2 (opción b)
Explanation:
Datos disponibles:
Plumaje gris es el fenotipo dominantePlumaje con manchas blancas es el fenotipo recesivoS es el alelo dominante para plumaje griss es el alelo recesivo para plumaje manchadoVariedad manchada representa el 4% de la población.Si ejemplares con ala manchada y genotipo ss representan el 4% de la población, entonces los restantes 96% corresponden a ejemplares grises homocigotas dominantes SS y heterocigotas Ss. Las frecuencias fenotípicas serán:
Plumaje gris (SS + Ss) = 96% = 0.96Plumaje manchado (ss) = 4% = 0.04De acuerdo al equilibrio de Hardy-Winberg, la suma de las frecuencias alélicas equivale a 1, y la suma de las frecuencias genotípicas también equivale a 1.
Frecuencia del alelo dominante = pFrecuencia del alelo recesivo = qFrecuencia de genotipo homocigota dominante = p²Frecuencia de genotipo heterocigota = 2xpxqFrecuencia del genotipo homocigota recesivo = q²Entonces,
p + q = 1p² + 2pq + q² = 1Si la frecuencia genotípica del homocigota recesivo es 0.04, entonces la raíz cuadrada de ese valor es la frecuencia génica del alelo recesivo. Esto es:
q² = 0.04q = √0.04 = 0.2A partir de la ecuación p + q = 1, podemos calcular el valor de p.
p + q = 1
p + 0.2 = 1
p = 1 - 0.2
p = 0.8
Entonces la frecuencia genotípica del homocigota dominante es p²
p² = 0.8² = 0.64
Y la frecuencia genotípica del heterocigota es
2pq = 2 x p x q = 2 x 0.8 x 0.2 = 0.32
Para corroborar esto, la suma de todas las frecuencias genotípicas debe dar uno.
0.64 + 0.32 + 0.04 = 1
Usable fresh surface water is relatively scarce. To many people, streams and lakes are the most visible part of the water cycle. Not only do they supply the human population, animals, and plants with the freshwater they need to survive, but they are great places for people to have fun.
Answers
Answer:
True.
Explanation:
Usable fresh surface water is scarce. Freshwater is not in excess on our planet. We can find it on lakes, lagoons, rivers, and swamps, but it is only 3% of the totality of Earth's water. The importance of this water is that it is the one that is suitable for humans, a large number of plants, and animals. This is why there are different methods to store and distribute fresh water amongst all the population and places that need it. Besides, the places where freshwater is, are great for activities, such as swimming, sailing, rafting, diving, fishing, etc.
Since freshwater is scarce and has so many uses, we must take care of it.

The correct statement is B) Part 1 are consumers, Part 2 are producers.
What are the two parts of food chain?Part 1 of the food chain describes organisms that are the end of the food chain, which would typically be consumers or animals that feed on other organisms, including plants and other animals.
Part 2 of the food chain refers to something that passes energy to plants and animals. This is typically the sun, which provides energy through photosynthesis to producers, or plants, that convert light energy into chemical energy stored in food. Producers form the base of the food chain, providing energy to all other organisms in the ecosystem through the food they produce.

Which of the following might restrict the growth of a population?
O Mild winters
O Increased predation
o Increased numbers of prey
O Ample rainfall
30 POINTS!!!!
Answers
Answer: Increased predation, and mild winters.
Explanation: As the prey population increases, there is more food for predators. So, as the number of predators increases, more prey are captured.
Mild winters would cause all of the plants to die, therefore prey would also die due to lack of food and cause predators to die as well for the same reason.
Side note: It might also be ample rainfall but I didn't know if they meant ample rainfall as in flooding or not, if it means flooding then that could be an answer, too. And I also wasn't sure if this was multiple choice or not.
Good luck! :)

Explanation: rewrite it
The energy of ultraviolet and shorter wave lengths of light is absorbed by interaction with the molecules in the atmosphere.
Explanation:
If there were no molecules in the atmosphere the high energy waves from the sun would strike the surface of the earth. The result would be that perhaps no living thing could survive.
Ozone and other molecules absorb the energy from the sun and undergo chemical reactions due to the energy absorbed.
