Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

How do both sodium and potassium ions travel
Answers
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.

Answer:
The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential. In each cycle, two potassium ions enter the cell while three sodium ions exit the cell . These ions travel against the concentration gradient. And this process requires ATP.

Answer:
false
Explanation:
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
Answers
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.

Answer:
A.
Explanation:
certain minerals form only under high heat and oressure that develop near volcano. That is why minerals vary among areas.
The option (C) is correct. Certain minerals form only in specific climates, and not all climates, are the same around the world.
What are minerals?A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.
Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.

Does DNA undergoes translation to produce proteins . RNA undergoes mutation to produce cell walls
Answers
Answer:
No
2. Yes
Explanation:
This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.
RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.

Answers
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.

Explain why when the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.
Answers
Answer: Each strand act as a template strand for another strand this way two strands are responsible for the production of two new strands. This way after the replication process two DNA molecules are produced.
Explanation:
S phase of the cell cycle is the synthesis phase of the cell cycle. This phase occurs after the interphase of the cell cycle. In this phase, the replication and synthesis of the DNA occur. The genetic material gets copied and doubled in this process before it enters into mitosis or meiosis. Each strand is utilized as a template strand for the synthesis of the complementary strand this way two molecules of DNA are produced. This way each cell contains a diploid set of chromosomes before it undergoes cell division into daughter cells in mitosis or meiosis.
Each strand act as a template strand for some other strand this manner strand is accountable for the manufacturing of new strands. In this manner after the replication system DNA molecules are produced.
S phase of the cell cycle is the synthesis section of the cell cycle. This section happens after the interphase of the cell cycle. In this section, the replication and synthesis of the DNA arise. The genetic material receives copied and doubled on molecular this system earlier than it enters into mitosis or meiosis.
Each strand is applied as a template strand for the synthesis of the complementary strand this manner molecules of DNA are produced. In this manner, every cell carries a diploid set of chromosomes earlier than it undergoes cell department into daughter cells in mitosis or meiosis.
What is the S phase?S phase (Synthesis Phase) is the section of the cell cycle wherein DNA is replicated, taking place among the G1 phase and G2 phase. Since correct duplication of the genome is essential to a successful cellular department, the techniques that arise for the duration of the S-phase are tightly regulated and broadly conserved.
Hence it states that the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.

A population of African lions share the same habitat. A small group becomes reproductively isolated
from the rest of the population (mating behaviors no longer match). What type of speciation is this?
a. Allopatric speciation
b. Sympatric speciation
C. Parapatric speciation
d. Peripatric speciation
Answers
Answer:
The correct answer is - B. sympatric speciation.
Explanation:
The allopatric speciation occurs in the population that is geographically isolated, parapatric speciation takes place due to reproductive isolation however they occupy distinct nice or habitat.
Peripatric speciation is shows resemblance to allopatric speciation in terms of preventing the exchange of genes however they occur in the small peripheral population.
Sympatric produces a reproductive barrier between the small population that shows change to the parent population.
