How does the process of gel electrophoresis produce DNA fingerprints? An electric current sorts DNA nucleotides according to their bases. O An electric current cuts a DNA strand into segments of various lengths O An electric current causes segments of DNA to move at different rates O An electric current supplies a charge to uncharged segments of DNA
Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

Group of answer choices
hydrosphere and biosphere
atmosphere and hydrosphere
hydrosphere and geosphere
atmosphere and biosphere
Answer:
hydrosphere and biosphere
Explanation:
The spheres of the Earth are lithosphere, biosphere, atmosphere, hydrosphere etc. Hydrosphere refers to the collection of all the water bodies on the surface of the Earth e.g oceans, lakes, rivers etc. On the other hand, biosphere refers to the collection of life on Earth e.g plants, animals, microbes etc.
In this question, Water availability is said to impact plant growth and the animals who depend on plants for food. These water availability and the living organisms (plants and animals) it impacts are interactions between the HYDROSPHERE AND BIOSPHERE.

Summary of the cell membrane structure.
Answer: The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell. The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.

What is a gene?
a section of a protein that codes for DNA
the alternate version of a trait
the visible trait in the F1 generation
a section of DNA that codes for a specific trait
Answer:
A gene is an order of nucleotides in DNA or RNA that encodes the structure of a gene product, either RNA or protein. During gene expression, the DNA is copied into RNA. The RNA can be directly functional or be the standard template for a protein that performs a function.

Which is the correct order the steps of the Cell Cycle:
A. Cytokinesis-Mitosis-Interphase
B. Mitosis-Interphase-Cytokinesis
C. Interphase-mitosis-Cytokinesis
Answer: C. Interphase-mitosis-Cytokinesis .
Explanation: Interphase is the "beginning" of the cell cycle, in this process, the cell prepares to go through the division process. Mitosis follows, and cell division occurs. Finally, cytokinesis sells up the process.

Answer:
The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life.
Explanation:
As carbon dioxide gas levels in the atmosphere increase, the temperature will
1. decrease
2. increase
3. stay the same.
4. The temperature on Earth is not affected by carbon dioxide gas.
Answer:
2. Increase
Explanation:
Carbon dioxide acts as a greenhouse gas that keeps the heat of the Earth from escaping back into space, much like how the glass of a greenhouse makes it nice and warm and steamy for plants.
Answer:
INCREASE
Explanation:
when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.
Which carbon compounds are formed over the course of the Calvin cycle? In what form of sugar to cells
store carbohydrates? (Hint: it is a product made AFTER the calvin cycle)
Answer:
The molecules of ADP and NAD+, resulting from the reduction reaction, return to the light-dependent reactions to be re-energized. One of the G3P molecules leaves the Calvin cycle to contribute to the formation of the carbohydrate molecule, which is commonly glucose (C6H12O6).
Explanation:
In the course of Calvin cycle, carbon dioxide molecules (CO₂) are combined with each other and with the electrons and protons from NADPH to form glucose (C₆H₁₂O₆). The glucose formed is stored in the form of starch.
What is Calvin cycle?Calvin cycle is a series of chemical reactions which convert carbon dioxide and hydrogen-carrier compounds into glucose. The carbon atoms used to build carbohydrate (glucose) molecules comes from carbon dioxide gas which is exhaled by animals.
The molecules of ADP and NAD⁺, resulting from the reduction reaction of Calvin cycle, returns to the light-dependent reaction to be re-energized. One of the G-3-P molecules leave Calvin cycle to contribute to the formation of the glucose molecule (C₆H₁₂O₆). This carbohydrate is stored in plants in the form of starch.

With three foods available, natural selection has favored Flock , which has increased the most in the
first three generations. Meanwhile, Flock has declined the most because its beak was the least
successful phenotype for the food available.
Natural selection has favored flock X the most.
Flock Z has declined the most.
Natural selection will favor the one who will adapt to its environment.What is natural selection?Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable.This variation means that some individuals have traits better suited to the environment than others.Organisms which will better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.This process causes species to change and diverge over time.

What is the role of mutations in creating variation in bird beak types?
Answer:
In order for a bird's beak to evolve into different a types, a mutation must occur first.
Explanation:
All evolution relies on mutations or changes to the DNA. Bird beaks adapt to the environment to be better suited to obtain food. A bird that used to have a pointy beak for stabbing bugs might move to an area with an abundance of seeds. Their DNA mutates so that their offspring can have short beaks to pick up seeds.

DNA:
DNA means deoxyribonucleic acid. It is a biological molecule that stores genetic information in living cells. DNA encodes the genetic information that is passed across to offsprings in all living cells. The genetic information is stored in the nucleotide base sequence that makes up the DNA molecule. Since DNA (genetic material) is present in every living organism, therefore, DNA can be found in humans, butterflies and trees.Learn more at: https://brainly.com/question/12499113?referrer=searchResults

What is the correct order to make a protein?
Answer:
The correct sequence of events in protein synthesis is transcription, then translation.
The correct order to make a protein is DNA >> RNA >> protein.
During gene transcription, a specific fragment of DNA (i.e., a gene) is used as a template to create a complementary RNA molecule known as a messenger RNA molecule.
Subsequently, this messenger RNA is then used as a template to create a polypeptide chain (i.e., a protein) in the ribosomes by a process called translation.
In conclusion, the correct order to make a protein is DNA >> RNA >> protein.
