Answer:

The orange is analogous to the Earth in having a relatively dense centre (mantle/core) and a much less dense skin (crust).

Answer:

A good anology is an oarnge because it has a thin/semi hard "crust" while the inside is much softer and bigger

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.

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.

The type of evidence that scientists use to infer ancestry includes morphological, molecular, and embryological evidence, and the fossil record.

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.

Answer:

i think it's GAATTC

Explanation:

The DNA strand above is cut with a restriction enzyme at the restriction site 5’-GAATTC-3’. The enzyme makes a staggered cut between the two T’s of the restriction site is GAATTC.

An isolated bacterial protein known as a restriction enzyme cleaves DNA at sequence-specific locations to create DNA fragments with a known sequence at each end.

For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.

There are at least 3,000 restriction enzymes, and they are all really cool. Each of these enzymes snips a certain DNA sequence, regardless of whether the DNA comes from a mouse, a bacterium, a fungus, or a human.

Therefore, The DNA strand above is cut with a restriction enzyme at the restriction site 5’-GAATTC-3’. The enzyme makes a staggered cut between the two T’s of the restriction site is GAATTC.

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.

Answer:

California

Explanation:

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.

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.

Hence, 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.

Answer:

Evolution provides evidence as to how animals such as birds are related to much older animals. Over time, species evolve and adapt to their surroundings to suit their habitat. Thus many different species pop up. This all doesn't happen in the blink of an eye, though.

Natural selection, which occurs during the process of evolution, has led to the presence of different species on the earth. Over time, individuals that have characteristics that make them more adapted to their environment have a higher chance of surviving and reproducing, passing those favorable characteristics on to their offspring.

The growth and diversification of different types of living species from ancestors during the history of the Earth is known as evolution. It is the development of heritable traits of biological populations through the processes of natural selection, genetic drift, and gene flow over many generations.

At every level of biological organization, including the species level, individual organisms, and molecules such as DNA and proteins, evolutionary processes give rise to diversity. By showing how genetic variation, natural selection, and other factors differentiate organisms over time and eventually give rise to new species, evolution shows why there are so many different species on Earth.

Therefore, Natural selection, which occurs during the process of evolution, has led to the presence of different species on the earth.
