Why would it be useful to extract and observe DNA?
Answer:
The ability to extract DNA is of primary importance to studying the genetic causes of disease and for the development of diagnostics and drugs. It is also essential for carrying out forensic science, sequencing genomes, detecting bacteria and viruses in the environment and for determining paternity.
Explanation:
Why are advantage traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce
Because they come from recessive genes
Because they come from dominant genes
Because the traits is an acquired phenotype

Write a hypothesis about the worms and lima bean plants. Be sure to answer the lab question, “How can the presence of one species benefit another in the same ecosystem?”
Hypothesis: If plants are grown in soil containing worms, then . . .
Answer:
A decomposing creature can decompose the bad items from a plant such as maybe dead leaves this would benefit the plant and the worm so their relationship would be considered Mutualism
Explanation:
The worm is a decomposing creature so it decomposes things like dead bugs and dead leaves and other items.
The relationship between the worm and plant is a mutual relationship because they are both being benefitted.
Of course, you will need to reword this answer but you may use it!

what is a DNA
what does DNA stand for
Answer:
Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Deoxyribonucleic acid
Explanation:
hope this helps...
Answer:
DNA is short for Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In other words, whenever organisms reproduce, a portion of their DNA is passed along to their offspring.
Why is a seedling related to a mature plant ??
(Pls answer)
Answer:
A seedling is a small plant with few leaves that is vulnerable to the elements. Eventually the seedling changes into a young adult plant. At this stage, the plant is bigger and may have more leaves. Thin branches will develop on young adult trees.

Achieving Anastasia’s Dream
Part 1
Remember Anastasia? To refresh your memory, she is a high school science teacher who has the dream of traveling the world. Anastasia decides that if she teaches a science course online, she will be able to work from anywhere in the world if she has an internet connection.
To construct her course, Anastasia needs to put together a rough course calendar. Her course is going to be on biology or the study of living organisms. The course has eight sections, with each section covering three to six subtopics. Each subtopic takes a week to cover.
Here are the sections in the course. To help Anastasia out, do some research online and find at least three subtopics for each section. (You could look at websites such as k12.com or textbook publishers such as Houghton Mifflin Harcourt or Prentice Hall to see what topics are typically covered in these types of courses).
Biology Foundations
Cells
Energy and Transport
Reproduction and Cell Division
Classical Genetics
Molecular Genetics
Human Body Systems
Ecology
That is a lot to fit in! Anastasia needs her course to consist of 36 weeks’ worth of lessons. Create a 36-week chart to help Anastasia fill in her lessons so that she knows when each topic will be covered. Fill in the subtopics that you found and spread them out evenly so that all topics are covered in Anastasia’s 36-week period. Anastasia will use your chart as a course calendar. Don’t forget that one subtopic takes a week to cover. Some sections may take more weeks to cover than others, depending on the number of subtopics included, and that is just fine!

Which of the following is evidence for continental drift?
A. There is one continent on Earth. .
B. Places with hot climates once had glaciers. C. There are no mountains in Africa.
D. North America has no volcancus.
Explanation:
its b i think if its right your welcome if its not let me know
The evidence for continent drift theory is that places with hot climates once had glaciers. Therefore, option B is correct.
What is continental drift theory?According to the Theory of Continental Drift, the continents of the Earth move relative to one another and appear to be drifting over the ocean floor together.
Wegener constructed a ring around the south pole using the regions that had been ice-covered. The conclusion of the theory is, Over the past 300 million years, the continents have drifted to their present locations after having formerly been a single, bigger continent.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift. Hence, option B is correct.

Grassland ecosystems in Texas have evolved to depend on periodic fires to return nutrients to the soil and encourage plant reproduction. Humans have prevented fires in many of these grassland areas, resulting in plant and animal communities with little diversity. Wildlife biologists often recommend purposefully starting fires called prescribed burns, which are monitored and controlled, in grassland ecosystems every 3 to 4 years. These biologists observe greater diversity in plant and animal life in the years following a prescribed burn. What natural processes are the biologists attempting to imitate
Answer:
Succession
Explanation:
The biologists were attempting to imitate succession.
Succession refers to a gradual change to the structure and species composition of a community over a period of time.
A newly colonized environment such as a bare rock forms a community is said to be in primary succession. Thereafter, the structure and composition of the community keep changing until a relatively stable community, otherwise known as climax community, is established.
Secondary succession happens when a disturbed community tries to regain its original dynamics in terms of species composition and structure. A climax community is often less diverse than a community that is still in active succession.
Hence, the biologists were attempting to imitate succession by burning/disturning a relatively stable, less diverse climax community of grassland in order to realize a more diverse community that will undergo secondary succession.

Succession

Answer: Stratum Corneum
Epidermis. The epidermis is the thin outer layer of the skin. It consists of 3 types of cells: Squamous cells. The outermost layer is continuously shed is called the stratum corneum
Explanation:
stratum corneum
The epidermis has no blood supply and depends on diffusion from the dermal cells for its metabolic needs. The dead-cell layer of the stratum corneum provides the protection from water loss that allows vertebrates to dwell on land
