6. Which of the following is a technique used by scientists to date fossils?
A fossilization scale
B. absolute dating
C. carbon imaging
D. plaster casting
Answer:
B. absolute dating
Explanation:
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.
Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events such as fossils by scientists.
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.

A. It produces body cells.
B. It causes alleles to go bad.
C. It prevents genetic problems.
D. It produces gametes/ sex cells.
Answer:
D. It produces gametes / sex cells.
Explanation:
Meiosis is a reductions division, so the source of the sex cells will produce the gametes, undergoing meiosis. The gametes will have half the number of chromosomes in a human body (23).

According to the evidence scientists have gathered, whales and hippos are more closely related than whales and fish. Describe the types of evidence a scientist uses to infer whether two species such as whales and hippos share a common ancestor.
The type of evidence that scientists use to infer ancestry includes morphological, molecular, and embryological evidence, and the fossil record.
What is evolution?
Evolution can be used to describe descendence from a common ancestor of two or more species.
The presence of homo-logous structures is indicative of common ancestry between different species.
These homo-logous structures can be observed during the embryo stage of organisms and the observation of the fossil record.

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.
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

Which of the following are enzymes involved in DNA replication? helicase DNA polymerase ligase all of the above
Answer:
All of the above
Explanation:
Helicase separates the two DNA strands to prepare them for replication. Without helicase, no replication would be possible, as the amino acids would not be accessible to be copied.
DNA polymerase is on the front lines of replication, directly copying the leading strand all at once. Because the lagging strand cannot be replicated in the same way due to its 3' to 5' orientation. DNA polymerase replicates in fragments while other enzymes fill in the gaps.
Ligase binds these fragments together to form a complete strand.
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.

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.

On the map, the state that is most likely to lose its forests due to mining is Montana, and Montana is located in the northern region of the United States. Here, there are both oil and forests, so for the oil mining, the forests are cut.
What is mining?Montana is a state in the western region of the United States and is known for its natural resources, including forests and minerals. The state has a diverse range of forest types, including coniferous forests, mixed forests, and deciduous forests, which provide important habitats for wildlife and recreational opportunities for people. However, Montana also has significant mineral and metal resources, including copper, gold, and silver, that are often extracted through mining. Mining can have significant negative impacts on forests and other ecosystems.
