How can we absorb earth’s heat

Biology
1 answer:
Llana [10]2 years ago
5 0

Answer:

Radiation.

Explanation:

The sun radiates the heat while the atmosphere takes up a good 70% of it. The remaining 30% is absorbed by the plants, ocean, and the organisms that are exposed to the sun.

You have isolated a new mutation in the T4 bacteriophage rII A gene and you map its location within the gene by recombination fr
pantera1 [17]

Answer:

A lethal mutation, thereby the resulting phenotype is not observed .

Explanation:

Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).

Biotechnology is best defined as what?
Lubov Fominskaja [6]
My answer -

<span> Biology is the study of living organisms. Biotechnology involves creating solutions to problems using living organisms. It's more like how mechanical engineering uses machines to solve problems or how computer engineering uses computers to solve problems.

The problems that biotechnology works to solve can range from medical treatments (like stem cells) to advancements in agriculture (disease or drought resistant plants, food with higher nutritional value) to industrial processes (bacteria developed to replace toxic compounds used to make paper, bacteria and algae that produce biofuels).

P.S

Happy to help have an AWESOME!!!! day :)

Which statement describes a characteristic of a spiral galaxy?
artcher [175]

Answer:

If your just looking for a description here you go.

Explanation:

Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

Hope this helps.

Una carga de 50 N unida a un resorte que cuelga verticalmente estira el resorte 5cm. El resorte se coloca ahora horizontalmente
ELEN [110]

Answer:

-110 N

Explanation:

Una carga de 50 N unida a un resorte que cuelga verticalmente estira el resorte 5cm. El resorte se coloca ahora horizontalmente sobre una masa y se estira 11cm. ¿Qué fuerza se requiere para estirar ese resorte en esa cantidad?

Solution:

La constante de resorte (k) es la relación entre la fuerza (F) y la extensión (d) como resultado de la fuerza aplicada, por lo tanto:

k = F / d

Dado que F = 50 N, d = 5 cm = 0.05 m. Por eso:

k = F / d = 50 N / 0.05 = 1000 N / m

La fuerza (F) requerida para provocar un estiramiento de 11 cm se da como:

F = -kx

x = 11 cm = 0,11 m. Por eso:

F = -kx = -1000 * 0,11 = -110 N

El signo negativo significa que el objeto se tira hacia el resorte.
