Answer:
Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel
Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.
The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.

How was life today similar and different to the Silurian period? ( animals, plants , organisms)
Answer:
The creatures developed in silurian period have evolved to live in sea bottoms.
Explanation:
Silurian life that is marine benthic which are bottom lying organisms belongs to the community of ecological zones that express themselves. As the gradients of temperature, pressure, and salinity. Consists of a community that is adapted to live in a darker region, used to lie in quieter environments that are in deep offshore water. These are much like the reef communities today as they do not tolerate excessive sediments. Prefer wave water that is shallow than 30 meters. These platforms are very gentle and are found over a hundred km gradients. Most of the fish represent the Silurian age and are widely distributed in marine environments. Examples of jawless fish, terrestrial fungi etc.on average how many toes does a human have? I think I have too many (not in a test, just wondering)

Is enzyme substrate complex concentration the product of enzyme concentration and substrate concentration?
Answer:
Yes
Explanation:
The enzyme substrate complex may be defined as the enzyme when interacting with the substrate at an active site and it produces a new product in the process. It is temporary molecule formed when the substrate comes in contact with the enzyme.
An enzyme is the molecule of a protein which acts like an organic catalyst and a substrate is a the molecule which interacts with the specific enzyme to form a product.
Therefore, the enzyme substrate complex concentration is the product of the substrate concentration as well as the enzyme concentration.
The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.

he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigmented phenotype. However, feeding silver salts to larvae results in adult flies that phenocopy the yellow phenotype. You are conducting epistasis experiments in fruit flies to understand the genetics of pigmentation. A rival research lab sends you a vial of yellow-bodied flies for your experiments. How can you tell whether these flies are mutants instead of phenocopies
Answer:
We could feed them with another type of food free of silver salts.
Explanation:
When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.
If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

Which is evidence of climate-forced sea level rise?
A. decreased temperature of oceans
B. submerging of low islands and coastlines
C. temperature changes for surface currents
D. increased carbon dioxide in the atmosphere
In this exercise we have to use the knowledge of climate changes that demonstrate the increase in the sea level, in this way we have that:
The submerging of low islands and coastlines or letter B.
The rise in sea level caused by global warming could reach 2 meters in height by the end of the 21st century. This rise in the oceans would leave thousands of kilometers of coastline at the mercy of flooding, jeopardizing the safety of 745 million people worldwide.
What could happen with sea level rise?The recent rise in sea level is a result of global warming through two main processes: expansion of sea water due to warming of the oceans, triggering its thermal expansion, and the melting of ice masses.

The two strands form a double helix linked by a series of paired bases. The base adenine is always linked to thymine and the base cytosine is always linked to guanine.
Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below
Complete question: Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below (the diagram is in the attached file)
What type of mutation is depicted in this sequence?
Answer:
The type of mutation is known as SUBSTITUTION.
Explanation:
Sickle cell anaemia is an inherited disease caused by abnormal shape of the red blood cell. This abnormal red blood cell contains less haemoglobin and cannot transport oxygen efficiently round the body. Sickle-shaped (abnormal) red blood cells result from a MUTATION in the gene that codes for hemoglobin.
Mutation is the random changes in DNA that alters genetic information and so introduce new characteristics. The different categories of mutations include:
--> Chromosomal mutation and
--> Point mutation.
SUBSTITUTION is a type of point mutation in which one base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand. From the diagram, a partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia, shows a substitution of an A for the middle T. This leads to GUA in the messenger RNA, which specifies the amino acid valine. The substitution of valine for glutamic acid at this particular position alters the chemistry of the hemoglobin such that it sticks together if it is not binding oxygen, creating sickling of the red blood cells.
