What problems still exist in using natural regeneration?

Biology

qwelly [4]3 years ago

Natural regeneration of forests and woodlands is the process by which new trees grow from seeds that have fallen and germinate where they have fallen.  The biggest problem with natural regeneration is that is unpredictable.  As a result, it cannot be used for commercial farming. For most of the last two or three hundred years, forests and woodlands have restocked by using transplants grown in nurseries. The young trees are planted in equidistant rows. This allows each tree the best possible change of optimal growth.

What type of inheritance involves genes that segregate and assort independently?
Butoxors [25]

Mendelian inheritance involves genes that segregate and <u>assort independently</u>.

Independent Assortment- According to Mendel's law of independent assortment, the alleles of two or more distinct genes are separately selected into gametes. In other words, an allele with one gene doesn't really affect the allele for another gene that a gamete acquires.

Genes- The fundamental genetic component transferred from parent to kid. Genes are composed of <u>DNA </u>sequences and are organized sequentially at specified sites on chromosome in the cell nucleus.

DNA- The molecule found inside cells that carries the genetic material necessary for an organism to grow and operate. This knowledge may be handed down from one generations to the next thanks to DNA molecules.

Imagine that a company is planning to build a new factory in your region that will provide hundreds of well-paid jobs, but will
Vesna [10]

I would support the factory if I lived 50 miles away from the planned factory location. However, I would be worried if I only lived one mile away from the planned factory, because of possible health effects, bad smells, and a potential decrease in property values.

<h3>What is Air pollution ?</h3>

Factories contaminate the air by blowing chemical vapors and smoke out through vents and smokestacks, and by burning waste in open dumps or incinerators.

  • Exhaust from generators, diesel trucks, and buses also fill the air with dangerous gases.

  • The amount of toxic gases that factories release into the air increases health and environmental damages. In factories, toxic materials and gases, like carbon dioxide and methane, are burned and pumped out into the atmosphere.

Que semejanzas y diferencias tiene el microscopio y el de Robert hooke
Sphinxa [80]

Answer:

- Microscopio de Robert Hooke: Aumento de 30X; monocular; con soporte rudimentario; enfoque de objetos transparentes y opacos

- Microscopio óptico actual: más sofisticado, binocular; compuesto por tres sistemas: sistema mecánico, sistema óptico (hasta 1.500 aumentos 1500 X), y sistema de iluminación.

Explanation:

El microscopio óptico fue el primer microscopio y marcó una nueva era en la biología y la medicina, siendo fundamental para la observación de estructuras celulares y subcelulares, lo cual permitió el desarrollo de diversas teorías tales como, por ejemplo, la teoría celular. La característica más importante compartida por los microscopios ópticos es el uso de la luz visible para visualizar las muestras. Los microscopios ópticos rudimentarios fueron popularizados en el siglo XVII, a partir del uso de Galileo Galilei. Posteriormente, en 1665, el científico inglés Robert Hooke usó su microscopio mejorado para observar muestras biológicas. El microscopio de Hooke era monocular y aumentaba la imagen 30 veces (30X), tenía un mejor soporte que los microscopios anteriores más rudimentarios, y podía enfocar tanto objetos transparentes como opacos. Actualmente, los microscopios ópticos están compuestos por tres sistemas: 1-sistema mecánico compuesto por piezas (es decir, una base, platina y brazo) donde están insertadas las lentes, un 2-sistema óptico compuesto por diferentes lentes conocidas como lentes oculares (microscopios binoculares) y lentes objetivos, las cuales permiten el aumento de las imágenes hasta 1.500 (1500X, con uso de aceite de inmersión), y 3-un sistema de iluminación para reflejar, transmitir y regular la intensidad de la luz.
