Answer: He didn’t grow a plant without fertilizer.

Explanation: Manu has nothing to compare his plant to. Meaning, he cannot prove that fertilizers help plants grow. He needs to grow a plant with and without fertilizer.

Helloyo!


Massive Star

They are typically greater then 8 molar masses. They typically have a quick main sequence phase, a short red supergiant phase and a death of a spectacular Cosmic event: Supernova. From there they can either become Neutron Stars or Black Holes

Medium-Sized Star

They usually have a Normal Main Sequence phase (Billions of years). From there they bevome Red Giants and expell their mass in a planetary nebula. From there they shrink and become white dwarfs first, then black dwarfs.

Verdadero o falso mediante el genotipo podemos determinar si existen dominancia en una característica
Murljashka [212]

Answer:

Verdadero

Explanation:

Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.

Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.

Genotipo:

  • Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)
  • Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)
  • Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)

Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.

Sin embargo, si tenemos los siguientes genotipos acompañando esta información:

  • MM--> Amarillo
  • Mm--> Amarillo
  • mm --> Rojo

Recién ahora podemos deducir que el caracter dominante es el amarillo.

Elan Coil [88]

Answer:Transpiration

Explanation: water cycle is the continuous movement of water on the Earth to ensure the availability of water.water is a universal solvent that is essential for the survival of living things.water cycle ensure that clean water is available.plants require water which is gotten from the soil.water is lost from the leaves of trees through transpiration.transpiration may also occur through the lenticels and stomata of stems.

the movement of water through the plant is called transpiration pull.this is responsible for the pull of water into the leaves.it increases the absorption of minerals from the soil and also cools the plant.

This water vapour that transpire from the plant,is condense as clouds, which then falls to the Earth as rain and the water cycle continue
