¿una barra de acero en puente de un camino de la alta montaña tiene una longitud de 50 cm cuando se encuetra a 30 C. Calcular que longitud tendra cuando su temperatura descienda a la -25 C ?
Answer:
L = 50,033cm
Explanation:
Para saber cuál es la longitud final de la barra de acero cuando la temperatura desciende, solo debemos aplicar la siguiente formula:
L = L₀ (1 + ΔT)
Donde:
L = Longitud final L₀ = Longitud inicial = Coeficiente de dilatación lineal del acero = 1,2x10-5 ΔT = Cambio de temperatura T₁ – T₀Entonces, considerando los datos brindados en el ejercicio problema, sabemos que:
L₀ = 50cm T₀ = 30ºC T₁ = -25ºC ΔT = -25ºC-30ºC = 55ºCL = L₀ (1 + ΔT)
L = 50 cm x (1 + (1,2x10-5 x 55ºC))
L = 50 x (1 + 0,00066)
L = 50,033cm

The narrator states that Dr. Taylor's work seems like it's from the "realms of science fiction." What did she mean by this statement?
Answer:
Growing organs and new body parts in a lab isn’t currently possible with modern medicine. Until now, we’ve only seen this kind of experiment prove successful in fictional stories and movies. If Dr. Taylor’s experiment is successful, it’ll be a huge leap forward for modern medicine.

Is air really dry? Or it’s just air
Answer:
It is just air
Explanation:
Answer:
It depends
Explanation: Dry air is a theoretical sample of air that has no water vapor. ... When the relative humidity drops below about 40% the air feels dry to skin. If very low relative humidities persist it can make the skin dry, lips chapped and can put more static in the air.

What would the complementary DNA bases for the strand ATTGAC be?
Answer: TAACTG
Explanation: Remember the base pairing rules: cytosine with guanine and adenine with thymine. To compliment the given strand, you'd have to choose the base that would pair with each individual nucleotide.
For example,
The pair to ACCTGAC would be TGGACTG.
Hope this helps,
Lacia
DNA bases for the strand ATTGAC is TAACTG which is the complementary base pairing rule adenine pairs with thymine and cytosine pairs with guanine.
What is DNA base pairing?Thymine, adenine, guanine, and cytosine are the four nitrogenous bases found in DNA. Adenine and thymine are joined by two hydrogen bonds, whereas guanine and cytosine are joined by three hydrogen bonds.
Base pairing that is complementary is what this is to create a DNA molecule, the DNA sequence of a gene must be copied, bases for the strand ATTGAC is TAACTG.
RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).
Therefore, DNA bases for the strand ATTGAC are TAACTG due to complementary base pairing.

A form of simple diffusion is Osmosis. In which direction will water flow in the process of Osmosis?
a- Water will flow away from the solutes, with the concentration gradient
b- Water will flow from low concentration to higher concentration
c- Water will flow with the solutes, against the concentration gradient
d- Water will flow towards the solutes (i.e. toward the higher salt concentration)
Answer:
Water will flow from low concentration to higher concentration.
Explanation:
Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction.
