Answer:

* Benefits of positive genetic engineering :-

Genetic modification is a faster and more efficient way of getting the same results as selective breeding. Improve crop yields or crop quality, which is important in developing countries. This may help reduce hunger around the world.

* Benefits of negative genetic engineering :-

- Potential Harms to Human Health

- New Allergens in the Food Supply.  

- Antibiotic Resistance.  

- Production of New Toxins.  

- Concentration of Toxic Metals.

Explain how chromosome behavior during meiosis ensures transfer of parental traits to offspring
gizmo_the_mogwai [7]

Explanation:

During meiosis, sister chromosomes of a homologous pair separate into different cells during gamete formation . This mainly occurs in Metaphase I of meiosis where the homologous chromosomes line up the metaphase plate in their sets. Each chromosomes of a pair are then pulled to different poles of the cells separating them. Each of these chromosomes carries a set of alleles of a gene. Each cell/gamete, therefore, carried half the set of alleles of all genes compared to autosomal cells. There many combinations of these sets that can occur depending on the number of chromosomes the organism has.

These cells when combined with that of another parent during fertilization, form a zygote that grows and develops into a mature organism. The offspring will bear the characteristics of both parents because it inherits half a set of chromosomes from both parents.

¿Qué áreas del conocimiento me pueden <br> aportar a la ejecución del proyecto? para un huerto
tensa zangetsu [6.8K]

Answer:

Conocimientos que pueden resultar muy útiles al momento de planificar un huerto:

- biología vegetal (características de las plantas que queremos producir)

- agronomía (características del terreno utilizado)

- condiciones ambientales (meteorología), como así también la disposición del lugar

Explanation:

Para iniciar un huerto en casa es necesario tener en cuenta una serie de factores que pueden influenciar en gran medida el éxito del proyecto:

-Tener en cuenta las características de las plantas que queremos producir es fundamental para lograr un óptimo crecimento. Por ejemplo, plantas que no resisten las heladas podrían morir en ciertas regiones, con lo cual las plantas deberían encontrarse en estos casos protegidas durante su desarrollo (por ejemplo, mediante un invernáculo).

- Buscar lugares bien iluminados. La presencia de luz es un factor fundamental para el crecimiento de las plantas.

- Riego y/o precipitaciones: tener en cuenta las necesidades hídricas de las plantas que queremos producir.

- Suelo: utilizar tierra abonada suele ser la mejor opción para brindarle a las plantas la mayor cantidad de nutrientes y así garantizar un óptimo crecimiento. En el caso de usar macetas, la presencia de huecos o el uso de vermiculita puede ser de gran ayuda para permitir la escorrentia del agua.

- Espacio: es necesario tener en cuenta el espaciado entre plantas para que puedan crecer normalmente.

-Tener en cuenta las plagas (insectos, nemátodos, etc) que podrían afectar el crecimiento de las plantas.

How does wet and dry barometer work?? Thnx
tatiyna

Wet barometer - The tool works by measuring atmospheric pressure to predict incoming weather. Since the glass is only filled halfway with water, the other half is exposed to the atmosphere. When the outdoor atmospheric pressure rises, the pressure in the glass decreases, and causes the water to move down the spout.

Dry barometer - A Torricellian barometer (sometimes called a mercury barometer) is an inverted (upside-down) glass tube standing in a bath of mercury. Air pressure pushes down on the surface of the mercury, making some rise up the tube. The greater the air pressure, the higher the mercury rises.

I hope this helps!
