Which best describes why gel electrophoresis works
Answer:
Scientists can determine the size of DNA fragments through a process known as gel electrophoresis. ... Large DNA molecules move slower and can be observed at the top of the gel, whereas smaller DNA fragments move faster and are seen at the bottom of the gel.

Explanation:
It could be that both the parents were heterozygous, meaning having a dominant and recessive allele for example Aa..after these are paired you would see that they will form a white fur offspring.

qué ventajas le trajo al ser humano el poder andar en 2 patas.
Answer:
The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".
[tex]{\sf{\boxed{\boxed{\tt\green{Las \: ventajas}}}}}[/tex]
La gran cantidad de ventajas que trajo el bipedalismo significó que todas las futuras especies de homínidos llevarían este rasgo. El bipedalismo permitió a los homínidos liberar completamente sus brazos, lo que les permitió hacerEnglish:
The advantages
The host of advantages bipedalism brought meant that all future hominid species would carry this trait. Bipedalism allowed hominids to free their arms completely, enabling them to make and use tools efficiently, stretch for fruit in trees and use their hands for social display and communication.#CarryOnLearning
What is cell wall???
Answer:
You can simply define the cell wall as a semi-rigid thick protective structure that surrounds the cell membrane of some types of cells for protection and defining the shape of the cell. The cell membrane alone cannot provide the required rigidity or strength. All living organisms are composed of cells.
How does mining impact the enviorment
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
Answer:
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust

What is a likely consequence
of this type of mutation?
A. The gene would result in a shorter
protein, possibly causing problems.
B. The gene would have a protein that
was too long, possibly causing problems.
C. The gene would be unaffected.
D. This would most likely be a positive
change.
Answer: it’s a
Explanation:
Just answered it
Most likely the consequence of this type of mutation is The gene would result in a shorter protein, possibly causing problems. Thus, option "A" is correct.
What is mutation?Mutations are the change in the nucleotide sequence of genetic material due to substitution, deletion or insertion of the nucleotides leading to changed protein.
There are many types of mutations.
If a mutation causes no effect on the protein produced, it is known as the silent mutation. It is usually due to substitution of one nucleotide with the same type of nucleotide as in glycine glycine mutation.
Thus, option "A" is correct.

The pieces made in replication are
assembled to complete the new virus
particles
The new viral nucleic acid and viral
proteins are replicated
The virus attaches to the host cell.
The original virus releases a protein that
causes the cell wall to burst (lysis), killing
the cell and releasing viruses.
The host's DNA is disassembled and the

Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain. e. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.
Complete question:
Which of the following statements is NOT correct about the flatworms?
A. There are three complete tissue layers.
B. Flatworms may be either free-living or parasitic.
C. Flatworms have a sac body plan, with only a mouth and no anus.
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
E. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.
Answer:
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
Explanation:
Flatworms are inferior organisms, meaning that they do not have nerves concentrated in a brain. Their nervous system is, in general, composed of nerve cords forming a net. The arrangement depends on each of the groups. They have one or more pairs of primitive eyes, which function is to find the light. These eyes cup-shaped and are composed of pigmentary cells.
Flatworms have bilateral symmetry. Their body is plane dorsoventrally and can be divided into two specular halves by the sagittal plane. This plane crosses through the body from the anterior extreme to the posterior extreme. The frontal plane divides the body into two different halves, the ventral one with the mouth and the dorsal one.
These organisms only have one opening in their bodies directed to the digestive system, which is the mouth.
Flatworms are aquatic and, most of them are marine animals, although there can be a few groups that inhabit freshwater. Some species might even be terrestrial. Most of them are free-living organisms, but there are also some parasitic forms.

El vapor se puede transportar a través de la atmosfera. A medida que el vapor se enfría , el agua se condensa en gotitas y forman y forman nubes y da como resultado
Answer:
Precipitación.
Explicación:
El agua se mueve del cuerpo de agua a la atmósfera debido al proceso de evaporación en forma de vapor. A medida que los vapores de agua se enfrían, el agua se condensa en gotitas y forma nubes que resultan en precipitaciones en forma de lluvia y nevadas. Los vapores de agua se vuelven más pesados cuando se condensan y debido a su cuerpo pesado no pueden permanecer en la atmósfera por lo que caen a la tierra en forma de lluvia y nevadas.
