Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a

dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. whats the students scientific question

Answer:

The student has observed That artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he infers that compost will make his plants grow faster than they grow in plain soil. that artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he is first that compost will make his plants grow faster than they grow in plain soil

Which best describes the life cycles of moss and angiosperm?
jonny [76]

Ans. Option (IV).

Mosses can be defined as non-vascular, flowerless plants that are found in shady or damp regions and reproduce via haploid spores. During reproduction in moss, haploid male gametes or spores are released into surrounding environment that fuse with female spores to form zygote that develop into mature sporophyte.

Angiosperms are vascular, flowering plants that reproduce by seeds. During reproduction in angiosperms, haploid male gametes or pollen grains are released into surrounding environment that fuse with female gametes or eggs to form zygote that develop into seed.

Thus, the correct answer is option (IV).

Generally speaking, what effect does temperature have on the solubility of gases in liquids?
MrRa [10]

With the increase in temperature, solubility of gases in liquid decrease.

Option A

<h3><u>Explanation:</u></h3>

Gases are soluble in liquid but it's solubility depends on temperature and pressure. As the temperature increases, the solubility of gases decrease. It is because with the increase in temperature, the kinetic energy of both the molecules of gas and the solvent increase. This leads to increase in molecular vibration and this makes the gas molecules escape the solution.

This makes the gas solubility vs temperature graph have a hyperbolic curve. As the temperature increases the solubility decrease and vice versa.

1.-La actividad consiste en que identifiques un ser vivo de tu comunidad, ubícalo en alguno de los niveles tróficos y posteriorm
ArbitrLikvidat [17]

Answer:

1.Ratón: se ubica en el segundo nivel trófico, es un consumidor primario que se alimenta de semillas

semillas (productores)---->ratón (consumidor primario)-->serpiente(consumidor secundario) --->zorro(consumidor terciario)

2.

  • Hay 4 niveles tróficos.
  • En el primer nivel se encuentran los productores.
  • En el segundo nivel se encuentran los consumidores primarios, estos se alimentan de los productores.
  • En el tercer nivel se encuentran los consumidores secundarios, los cuales se alimentan de los consumidores primarios
  • En el cuarto nivel se encuentran los consumidores terciarios que se alimentan de los consumidores secundarios.
  • Al consumir lo que se encuentra en el nivel anterior obtienen energía para subsistir y mantener el equilibrio del ecosistema.
  • Los niveles tróficos son los lugares que ocupan un determinado grupo de seres vivos en relación a otros por la energía que tienen y que pasan al siguiente nivel. Se ve en la cadena alimentaria, donde la energía que se obtiene de los nutrientes del nivel anterior siempre es destinada a seres mas grandes en tamaño, es decir que están en el siguiente nivel trófico y necesitan mas energía.

Explanation:

El ratón es un animal herbívoro, es decir que se alimenta de plantas y hierbas, por ende se ubica en el segundo nivel trófico porque consume a los productores. Estos últimos reciben este nombre porque producen su propio alimento a diferencia del resto de los niveles en donde los seres vivos se alimentan de animales o insectos que estén en niveles inferiores.

La energía que obtiene el ratón al consumir a los productores se utiliza en el metabolismo y en las diferentes reacciones que hacen que se mantenga vivo hasta que este es consumido por otro animal transfiriendo la energía al siguiente nivel. Esta cadena sigue hasta llegar al consumidor terciario. En todos los niveles intervienen los descomponedores que degradan los restos de los seres vivos para obtener energía y nutrir la tierra, de esta forma comienzan nuevamente la cadena alimentaria.

Cells in culture will absorb amino acids form the surround culture medium. If radioactively labelled glycine,
Norma-Jean [14]

Answer:

A

Explanation:

Radioactively labelled amino acids will be found in the ribosomes. These are the organelles that are the site of protein synthesis.

Amino acids are taken up into the cytoplasm from the surrounding cell culture medium. Amino acids are then bound to tRNAs (with the enzyme aminoacyl-tRNA synthetases) and taken to the ribosome, where they are assembled into a polypeptide chain by the translation machinery.
