Explanation:
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 explanation best describes why sexually reproducing organisms have greater genetic
variation than asexually reproducing organisms?
Helppp
Answer:
think of it this way lol
Explanation:
In asexual reproduction, you are essentially producing clones of the parent. There is no genetic variation between parent and offspring - think of mitosis.
In sexual reproduction, you have several chances for genetic variation. The first occurs in meiosis 1, when homologous pairs line up and crossing over occurs. Then in meiosis 2, different combinations of chromosomes (some from mother, some from father) could end up in the gamete cells. Finally, when the gametes (egg and sperm/spore) come together in fertilization, that represents a brand new combination of chromosomes, and therefore alleles, than either of the parents had.
2. Which fruit provides an analogy as to the thickness of the

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
Through which of the following processes is energy formed in the form of glucose?

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.

HELP PLEASE ! Which statement best describes the result of meiosis?
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).

D. the joining together of exons to form the gene

Most genetic diseases are caused by recessive alleles. Why? (1 point)
A) Recessive alleles are never expressed, so they confer no disadvantage to survival.
B) Dominant alleles that cause disease are removed from the population over time, but recessive alleles can
persist indefinitely in the population.
C) Genetic diseases occur only in heterozygous gene pairings.
D) The statement is untrue. Genetic diseases are most commonly caused by dominant alleles

B is the answer beacuse yeah sorry if wrong
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!

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.
