Answer and Explanation:
Lipids are non-polar molecules, so they do not interact preferentially with polar molecules but they can interact with each other. In a polar medium, such as water, the hydrocarbons in lipids aggregate each other, in order to minimize contact with surrounding polar molecules. The interaction between non-polar solutes with polar surroundings exclusion is called hydrophobic interaction.

When we doing Strawberry Extraction, why do we need to remove the air as much as possible before seal the bag?
to keep it preserved and delicious
Answer:
Why do we need to cool the mixture? DNases or restriction enzymes that destroy DNA are present in the cell's cytoplasm. They are there to protect the cell from invasion by viruses. Once the nuclear membrane is destroyed by the soap, the DNA is now susceptible to the DNases and will quickly be degraded.
Explanation:
When you added the salt and detergent mixture to the smashed strawberries, the detergent helped lyse (pop open) the strawberry cells, releasing the DNA into solution, whereas the salt helped create an environment where the different DNA strands could gather and clump, making it easier for you to see them.
Duplicate chromosomes line up (in a single line) during metaphase
Answer:
Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. ... These separated sister chromatids are known from this point forward as daughter chromosomes.

PHET skate park . Consider this equation: Kinetic Energy = ½ mv2. Which of those variables is changing as the skater moves up and down the track?
Velocity is the variable which is changing during motion of skater.
Impact of velocity on energyVelocity is the variable which is changing when the skater moves up and down the track because moving upward on the slope decrease the speed of the skater while on the other hand, velocity increases when moving downward on the slope.
Mass of the body which is skating remain constant or can't change with height. Mass is the amount of matter present inside the body so we can conclude that velocity is the variable which is changing during motion of skater.

2. Codominance: Diricrawls are plump, fluffy-feathered, flightless birds. Feather color
is co-dominant; FF have pink feathers, PP have purple feathers and mottled diriclaws (FP)
have both pink and purple feathers. Pink feathered diricrawls are very rare and prized by
collectors. If you breed a pink diriclaw with a mottled diricrawls, what percentage of their
offspring will be pink feathered? (show all of your work and use a Punnett square).
Answer:
The correct answer is - 50% or 1/2.
Explanation:
In codominance both alleles express their traits and blend to make new traits, there is no dominance or recessive pattern found. In this question, there is FF have pink feathers, PP has purple feathers and mottled diriclaws (FP). Then a cross between pink feathers and mottled diriclaws would produce offspring:
F F
F FF FF
P FP FP
Here two out of four have pink feathers. That is 50%
explain how the structure of ATP relates to its function
Answer:
ATP functions as the energy currency for cells. ... The structure of ATP is that of an RNA nucleotide with three phosphates attached. As ATP is used for energy, a phosphate group or two are detached, and either ADP or AMP is produced. Energy derived from glucose catabolism is used to convert ADP into ATP.

Why can mRNA leave the nucleus, but
DNA cannot leave the nucleus?
A. DNA is single stranded and is too long to leave the
nucleus.
B. RNA is singled stranded, DNA is double stranded, so
RNA is smaller than DNA.
C. DNA can leave the nucleus through special openings in
the nuclear membrane.
D. DNA and RNA can both leave the nucleus.
Answer:
B
Explanation:
Your DNA is stored in a double helix formation. Which means it has two long strands and would be too long to leave the nucleus. C and A are incorrect. DNA is double stranded, so we can eliminate A. There are NO special openings in the nucleus. Only the cell membrane. C is eliminated.
Option D is incorrect because DNA is transcribed into the cell membrane, there is no way for it to leave. RNA is a single strand.
mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.
What is DNA?DNA stands for Deoxyribonucleic acid. It may be characterized as a type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. These molecules allow this information to be passed from one generation to the next.
DNA is not a single-stranded structure. While RNA is present in a single stranded form in the cell. Due to this, the double-stranded structure of DNA seems longer than that of RNA to cross the nuclear membrane in the cell. As a result of this, RNA can easily leave the nucleus but DNA couldn't.
Therefore, mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.

¿Qué puedo hacer para que mis hijos tengan un ambiente sano, alimentos y recursos naturales suficientes?
Answer:
proteger el medio ambiente mediante la utilización de energías renovables, crear conciencia a través del uso sustentable de los recursos naturales, disminuir el consumo, reciclar y fomentar la utilización de compuestos biodegradables
Explanation:
La cultura del descarte en conjunción con el aumento creciente en la población mundial ha conducido a graves problemas ecológicos que afectan actualmente a la sociedad tales como, por ejemplo, el cambio climático, el cual plantea una preocupación muy seria acerca de las condiciones en las que recibirán nuestro planeta jóvenes y futuras generaciones. La mejor manera de garantizar un ambiente limpio, saludable y sostenible es fomentando el uso de energías renovables y simultáneamente reduciendo al mínimo el consumo innecesario de recursos (como por ejemplo, a través del uso eficiente del agua o electrodomésticos de bajo consumo energético). También reciclar materiales, utilizando materiales biodegradables y evitando compuestos no reciclables (tales como plásticos) representan buenas ideas para un mañana sin riesgos ambientales.

Why would cells from the same organism have different functions?
Answer:
Explanation: Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. ... When this factor cannot be expressed, these cells do not develop at all.
