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.

Answer:

A. Tissue

Explanation:

The cells join together to form tissues. So, option (A) is the correct answer.

Answer:

A. Tissue

Explanation:

Just as cells join together to form tissues

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.

Answer:

Water

Explanation:

A medium is the substance through which a wave can propagate. Water is the medium of ocean waves.

Answer:

The correct answer is - cells are the basic unit of life.

Explanation:

As it is given and also known that there are many unicellular organisms exists and they do not require the multicellular body to live their life or survival. Multicellular organisms are made up of various cells joined together to form a complex organization.

Anything less than a cell can not live or survive and also do not called a living entity. So, from above we can say the basic unit of the life is cell.

DNA ( Deoxyribose Nucleic Acid ) is a molecule.

and its where a bunch of atoms stuck together.

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.

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.

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.

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.

Answer:

D) Finches that eat plants all have very large beaks.

Explanation:

Finches that eat plants have very large beaks because plants are big in size which can only be eaten with large beak. Those finches that lives in the environment having nuts and seeds having large beaks due to the big size of seeds and plant parts so that's why we can say that finches who feeds on plants parts have larger beaks as compared to those finches who feeds on insects.

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]
