DNA is a double stranded molecule that belongs to a group of larger molecules (macromolecules) called NUCLEIC ACIDS.
Nucleic acids are formed by joining together many smaller molecules called NUCLEOTIDES.
Nucleotides consist of:
- Pentose sugar (pentagon)
- Phosphate group (circle)
- Nitrogenous (rectangle)

Answers
Answer:
A: gene flow
Explanation:
have a nice day
The notes describe gene flow. Therefore, option (A) is correct.
What is gene flow?Gene flow is the transfer or exchange of genetic material, specifically genes, between different populations of the same species. It occurs when individuals from one population migrate or disperse to another population and successfully reproduce, introducing their genes into the gene pool of the receiving population.
Gene flow can happen through various means, such as the movement of individuals, migration, or the dispersal of pollen or seeds. It is an important mechanism in evolution as it facilitates the transfer of genetic variation between populations. By introducing new genetic material, gene flow can increase genetic diversity within a population and reduce genetic differences between populations.
Gene flow can have significant impacts on the genetic makeup of populations, influencing their adaptability, genetic structure, and evolutionary trajectories. It can counteract the effects of genetic drift and natural selection, promoting the sharing of beneficial.

How does a cladogram represent hypothesized evolutionary relationships?
Answers
Answer:
A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. Cladograms represent hypotheses about the evolution of organisms and are subject to revision when theories are disproved and additional data become available.
Explanation:
When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released.
Which identifies the energy transformations that take place in Anna’s body as this process takes place?
A.) Mechanical energy is converted to kinetic energy, which is then converted to potential energy.
B.) Chemical energy is converted to thermal energy and electrical energy.
C.) Electrical energy is converted to chemical energy and thermal energy.
D.) Mechanical energy is converted to potential energy which is then converted to kinetic energy.

What do you already know about photosynthesis and cellular reputation? (At least three sentences) BRAINLIEST INVOLVED AND
Answers
I'm not sure what YOU already know about photosynthesis and cellular respiration.... however, you SHOULD know that the two are beautifully linked to one another!
Photosynthesis equation:
6CO2+6H2O -> C6H12O6+H2O
Cellular respiration
C6H12O6+H2O -> 6CO2+6H2O
Notice something? The substrates of one equation are the products of the other! We rely on plants for their photosynthetic reactions - and plants benefit from us (not really because there is already a TON of CO2 in the atmosphere) from our cellular respiration
***we like their oxygen and they like our carbon dioxide!

Thus bacteria can be attacked by antibiotics but viruses cannot.
Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria.

Describe using scientific terms, how plants turn sunlight into energy? Make sure to refer to chemical equation to photosynthesis and discus the reactants and products.
Answers
Answer:
Explanation:
Photosynthesis is the process plants use to convert sunlight into energy. Oxygen is produced as by-product of photosynthesis when the water absorbed by plants is 'split'. It is one of the most important reactions on the planet because it is the source of nearly all of the world's oxygen.
Answer:
- Possible Answer #1: The chemical process that coverts sunlight into energy is called photosynthesis. This is represented with the equation 6CO2 + 6H2O → C6H12O6 + 6O2. (Carbon dioxide + water + a source of light energy = oxygen and glucose. Using the pigment chlorophyll found in plant cells, the plant is able to produce glucose (the main source of ATP) by developing both carbon dioxide, water, and light energy into products that help support the cell's function. Oxygen is the waste product excreted by the plant as a direct result of photosynthesis itself.

Exocytosis is a process by which cells A. remove bulk material from the cell via wosicions
B. remove bulk material from the cell via pores C. bring bulk material into the cell via vesicles D. bring bulk material into the cell via pores
Answers
B. remove bulk material from the cell via pores
Exocytosis is the process by which cells B. remove bulk material from the cell via pores
The prefix, "exo" suggests "out" or "external". Also, the suffix, "cytosis" relates to anything that has to do with cells.
Exocytosis in concise terms can be described as the movement of large polar molecules and waste materials out of a cell through pores by active/bulk transport mechanism. This mechanism is the opposite of endocytosis.
The process involves:
the formation of an encapsulated membrane, which is a vesicle formed within the cell containing the packaged materials that is to be expelled.the vesicle is moved to the cell membranethe vesicle is expelled through the pores and the contents are released out of the cell.See attachment for image showing the mechanism of Exocytosis.
Thus, the right option is B. remove bulk material from the cell via pores.

Edith Widder: Glowing life in an underwater world
1. On her first open-ocean dive in the Santa Barbara Channel, Widder says she dove down to 880 feet and turned off her lights. Explain why she did this and how she described what she saw?
2. If you happen to be on a ship and go to use the bathroom at night without turning on the light, why does Widder explain you might think you are having a “religious experience”?
3. Why are most people who are studying bioluminescence today focused mainly on the chemistry behind it? What does the Nobel Prize have to do with this?
4. What makes bioluminescence an important factor of survival for so many animals? Provide one example Widder gives to explain this.
5. Why is Widder dissatisfied with the way we explore the ocean? What are the two main ways we learn about what lives in the ocean that she describes?
6. How does Widder tell the difference between the species she observes in the deep ocean? Give an example of a species she identifies based on this observation.
Answers
Answer:
1. She turned off the lights because she knew that she would see a phenomenon of animals making light called bioluminescence. She described that she was totally unprepared for how much there was and how spectacular it was. She saw chains of jellyfish that were pumping out a lot of light; and puffs and billows of what looked like luminous blue smoke and sparks of blue light from the thrusters.
2. The head on ships which are the toilets on ships are flushed with unfilltered seawater that often has bioluminescent plankton on it. So, if you stagger into the haed late at night and you're toilet-hugging sick, that you forget to turn on the light, you my think that you're having a religious experience.
3. They are focusing on the chemistry because these chemicals have proved so incredibly valuable for developing antibacterial agents, cancer fighting drugs, testing for the presence of life on Mars, detecting pollutants in our waters which is how it is used at ORCA. In 2008, the Nobel Prize in Chemistry was awarded for work done on a molecule called green fluorescent protein that was isolated from the bioluminescent chemistry of a jellyfish, and it has been equated to the invention of the microscope, in terms of the impact that it has had on cell biology and genetic engineering.
4. What makes it important for the survival of many animals is for the animals that are trying to avoid predators by staying in the darkness, light can still be very useful for the three basic things that animals have to do to survive: and that's find food, attract a mate and avoid being eaten.
5. The primary ways that we know about what lives in the ocean is we go out and drag nets behind ships. The other primary way is we go down with submersibles and remote-operated vehicles. Doing that there are bright lights and thrusters that disturbs the animals and makes then go away.
6. She was able to tell the difference between the species by the types of flashes they produced like the big explosions, sparks, are from a little comb jelly.
