Que semejanzas y diferencias tiene el microscopio y el de Robert hooke

Biology
1 answer:
Sphinxa [80]3 years ago
5 0

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.

A genotype is controlled by the sex cells combining to form an organism. True or False
myrzilka [38]

True

A genotype is the combination of genes in its DNA of the organism that determines its traits

Explanation:

Gametes from parents contribute different alleles of genes to their offspring. This why gametes carry only one copy of genetic material of the organism. They later fuse to form a zygote with a full genetic copy and capable of developing into an full organism.

Depending on which kind of alleles the parents pass down to the offspring will determine the offspring's genotype. The genotype of the offspring will, on the other hand, affect its phenotype which is the outward characteristic. An example is the sickle cell trait. If both gametes from the parents contribute the recessive alleles of the gene, then the offspring will be homozygous recessive for sickle cell genotype and this will show in the phenotype pf the person who will have sickle cell shaped blood cells.

A normal fault is formed from compressional stress. select one:<br> a. true<br> b. false
Dmitry_Shevchenko [17]

Answer: False.

Explanation:

A normal fault is a type of fault in which the hanging wall drop down in relative to the footwall. It is caused by tensional stress, when two block of rocks pull apart from each other. Normal fault normal happen in areas that are undergoing extension or stretching.

Reverse fault are caused by compressive stress.

Consider the following food chain: garden plants are eaten by snails, which are eaten by birds, which are eaten by the household
SIZIF [17.4K]
The garden plants and snails stay balanced as they are still being eaten. However, if the cat is removed, the birds will overpopulate and then the snail would be eaten and decrease faster which gives garden plants an increase in population due to the decrease in snails. Hope this helps!

Which of the following is an example of reproductive isolation? two populations of finches that cannot produce viable offspring
OverLord2011 [107]

The correct answer is A. Two populations of finches that cannot produce viable offspring

Explanation:

Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.
