Every known living organism on Earth is classified and named by a set of rules. Those rules are used by all scientists around the planet. The taxonomic way of classifying organisms is based on similarities between different organisms
When classifying organisms, scientists look at many characteristics some of which are the number of cells, coll structure or body form

In addition to glucose the cell needs to drive cellular respiration:
A oxygen
B carbon dioxide

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! =)

Why is it helpful for frogs to have bulging eyes?
Answers
Answer:
It is helpful for frogs to have bulging eyes because it allows them to see in all directions such as in front of them, to the sides, and partially behind them. The frog's eyes that are positioned above their head give them a field of vision of almost 180 degrees, this helps them spot predators and prey easier and quicker.

But the parents of many of your patients cannot afford the cost of vaccinations. You hear of a new approach that would reduce the cost to a fraction of its current price: genetically modified fruits and vegetables that contain various vaccines. By simply eating a banana, a child could be protected against disease without getting a shot!

What is Genetically Modified food?
Genetically modified foods are also known as GM foods or genetically engineered foods or bioengineered foods. These are produced from organisms whose DNA has been altered using genetic engineering methods.
These are derived from organisms whose genetic material (DNA) which has been modified in a way which does not occur naturally, e.g. through the introduction of genes from a different organism.
There are several benefits of GM foods in agriculture like
1. Increased crop yields
2. Reduced costs for food or drug production
3. Reduced need for pesticides
4. Enhanced nutrient composition and food quality,
Thus, encouraging patients to eat genetically modified fruits and vegetables which protect them from getting sick. So, the correct option is (A).

Part #2: This passes energy to plants and animals.

C) Part 1 are producers, Part 2 is the sun
D) Part 1 are producers, Part 2 are consumers

Answers
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.

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.

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

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.
