Explain the general distribution of life in aquatic systems as a function of chemistry, geography, light, depth, salinity, and temperature.

Answers

Different types of organisms can exist in a variety of aquatic environments due to the fact that they can vary significantly from place to place and that organisms within each water system will have evolved to adapt to their specific environment.

How does light affect aquatic life?

Sunlight plays a vital role in the ocean’s ecosystem. First, sunlight enters the water column, warms it, creates currents, and is then absorbed by phosphorous-rich phytoplanktons. Phytoplanktons use the energy captured by phototrophs (pigments like chlorophylls) to convert water and nutrients into organic matter.

Light availability determines the types of organisms that can live in a particular part of an aquatic environment. The deeper the water depth, the less light it can penetrate until there is no light at all.

The salinity of water affects its density which in turn affects the movement of ocean currents. It may also affect marine life which needs to regulate the intake of salt water. There is a relationship between salinity, temperature, and water density. Therefore, any change in temperature or water density will affect the salinity of the water in the area.

Water chemistry parameters (pH, dissolved organic carbon, and hardness) play a role in metal toxicity by influencing the bioavailability of aquatic species of metals in water.

Discuss the benefits and drawbacks of
using solar energy and wind energy.

Answers

Answer:

hmm I'd say something like "Solar and Wind energy systems are renewable sources and ultimately are healthier for the planet, the drawback is that other resources (i.e oil and coal) tend to be cheaper"

Answer:

Solar Energy:-

Benefits-

Solar power is completely cleanIt produces no air pollution, no water pollution, no greenhouse gas effects and carbon - free alsoNo harmful emissions are released when electricity is being produced by solar panels.It also reduces the need for finite resources.

Drawbacks-

Solar Energy Storage Is ExpensiveUses a Lot of SpaceIts Weather-Dependent, slthough solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.Initial cost of purchasing a solar system is fairly high.

Wind Energy:-

Benefits-

Wind is a domestic source of energyIt's a clean fuel sourceIt's sustainable and causes no harmful emissions. Wind energy is a green energy source and does not cause pollution.

Drawbacks-

Wind turbines are prone to noise disturbances.The wind is inconsistentWind turbines involve high upfront capital investment.Installation can take up a significant portion of land.

4. The human population has experienced unchecked growth for the past 200 years. What does "unchecked" mean? A. Slow b. At a steady rate c. Unrestrained d. Dangerous

Answers

Answer:

B

Explanation:

The correct option would be B

The human population experiencing unchecked growth for the past 200 years does not mean that there were no restraining factors that limit the population. Factors such as death, competition for resources, diseases, etc., were still present.

Despite the limiting factors, the population has been growing. Hence, the correct word to replace 'unchecked growth' would be 'at a steady rate'.

Slow and dangerous really have nothing synonymous with unchecked growth.

The correct option is, therefore, B.

The variable h represents the number of hours spent doing yard work and the variable d represents the amount of money earned how many hours spent doing yard work and the variable d represents the amount of money earned how many hours in all will it take Whitney to earn 15$

Answers

Answer:

[tex]4\frac{1}{11}[/tex] hours

Explanation:

Given

See attachment for graph

First, we determine the equation of the graph.

Pick any two points from the graph

[tex](h_1,d_1) =(18,168)[/tex]

[tex](h_2,d_2) =(36,366)[/tex]

Calculate the slope (m)

[tex]m = \frac{d_2 - d_1}{h_2 -h_1}[/tex]

This gives:

[tex]m = \frac{366 - 168}{36 -18}[/tex]

[tex]m = \frac{198}{18}[/tex]

[tex]m = 11[/tex]

The equation is then calculated as:

[tex]d = m(h - h_1) + d_1[/tex]

This gives:

[tex]d = 11(h - 18) + 168[/tex]

Open bracket

[tex]d = 11h - 198 + 168[/tex]

[tex]d = 11h-30[/tex]

So, the number of hours to earn $15 is:

[tex]d = 11h-30[/tex]

[tex]15 = 11h -30[/tex]

Collect like terms

[tex]11h = 15 + 30[/tex]

[tex]11h = 45[/tex]

Solve for h

[tex]h = \frac{45}{11}[/tex]

[tex]h = 4\frac{1}{11}[/tex]

Why did Gregor Mendel choose to use purebred plants in his experiments?
A They reproduce sexually.
B They exhibit only one form of a trait.
C They have a variety of traits.
D They reproduce asexually.

Answers

Answer:

B

Explanation:

Gregor Mendel chooses to use purebred plants in his experiments because they exhibit only one form of a trait. The correct option is B.

What is Mendel's experiment?

Mendel altered pure pea plant lineages. First-generation hybrids (F1) displayed dominant qualities like purple flower color while hiding recessive traits like white bloom color.

But in second-generation (F2) pea plants, recessive characteristics returned in a 3:1 ratio (dominant to recessive). Every pea plant has both male and female reproductive organs, and they all typically procreate by self-pollinating.

This was crucial to make sure that there were no other factors influencing the result of the cross when he crossed two plants with different features.

Therefore, the correct option is B, They exhibit only one form of a trait.

Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mitosis y meiosis

Answers

Answer:

la vida no podría continuar sin los procesos de división celular  

Explanation:

La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.
