A very small percentage of all living organisms will become fossils, as the process requires specific and rare conditions. Fossil evidence shows that existing species at any time represent only about 0.2-2% of species that have existed. Extinction also contributes to the rarity of potential fossils.
Explanation:Considering all of the organisms living today, only a very small percentage will eventually become fossils. The process of fossilization is rare and occurs under specific conditions; remains must be covered quickly by sediments or preserved through other extraordinary means, such as being trapped in tree resin or frozen in glaciers. Given that fossils are critical for understanding the Earth's history and the evolution of life, their scarcity highlights their value for scientific research.
Based on scientific analysis, the average lifespan of a species based on fossil evidence is about 1-10 million years, suggesting that at any given time, existing species represent only a fraction—about 0.2-2%—of all the species that have ever lived. Furthermore, extinction is an ongoing process, affecting a significant portion of living species, which also influences the potential for organisms to become fossilized.

the diagram below represents the time a cell spends in the two main phases of the cell cycle. what is happening in the phase represented by the yellow area?
D) the cell is dividing
Answer:
The correct answer will be option-D.
Explanation:
The cell cycle is the sequential steps of events which explains the duplication of the genetic material and division of the cell into daughter cells.
It usually takes place in 24 hours where it is divided into four phases: Gap 1 (G₁), Synthesis phase, Gap 2 (G₂) and Mitotic phase (M phase). M phase can be marked easily as it takes place during the short period of time usually in one hour.
In the given question, the marked area represents the shortest phase or M phase during which cell divides its nucleus and cytoplasm, therefore, is considered the cell division phase.
Thus, option-D is the correct answer.

The planets closest to the Sun are the inner, or terrestrial, planets and are similar to Earth in some ways. They are rocky and dense, have few moons, no rings, and are relatively small. These planets also differ in many ways, as shown in the chart. For example, Venus is the hottest planet on the chart, even though Mercury is closer to the Sun. The temperature difference between Venus and Earth is significantly greater than the difference between Venus and Mercury, even though Venus lies close to midway between those two planets. Which statement elaborates on the cause of this wide range of temperatures between terrestrial planets?
The correct answer is - the atmosphere.
All of the terrestrial planets have atmospheres, but all them differ in their composition and density too. Venus has the highest temperature of the terrestrial planets, higher even then Mercury despite being closer to the Sun, because it has very dense atmosphere. Also, the key moment with the dense atmosphere of Venus is that it is mostly composed of carbon dioxide. The carbon dioxide is a gas that has the ability to trap the solar radiation into the atmosphere, so the more there is from this gas, the hotter it will be, and Venus has exactly that.

When scientists uncover a fossil, they record the precise location where the fossil was found. Does this location provide useful evidence for conclusions about the fossil and evolutionary processes?
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
B. No. Evidence for evolution comes only from body structures, not the environment of organisms.
C. Yes. Evolution occurs only in certain locations on Earth, and not others. D. No. Fossils and living species are distributed evenly across all of Earth's land and water.
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
Answer:
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
Explanation:
Data shows that presence or the absence of the continents and the islands provides evidence of the descent and shows us the specification of species. As the same species would be found in the same habitats that are capable of supporting a particular species in a geographical area as Africa or South America. Evidence have also been found in Australia that has marsupials like the kangaroos and quills that were not present in Africa and in small numbers in south America. Similarly, the fossils are found in areas know adjacent to each other and through the process of the continental drift, they diverged in wide geographical areas.As precipitation infiltrates into the subsurface soil, it generally forms an unsaturated zone and a saturated zone. In the unsaturated zone, the voids—that is, the spaces between grains of gravel, sand, silt, clay, and cracks within rocks—contain both air and water. Although a lot of water can be present in the unsaturated zone; why can't this water be pumped by wells?
A)
Soils, like clay, absorb water quickly.
B)
Sinkholes collect water above the water table.
C)
Land with no slope lets water runoff at a fast rate.
D)
Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Answer:
d
Explanation:
Answer:D) Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Explanation: Water in the subsurface soil zone is held together by capillary forces. It is also used by plants to carry out their life processes. The soil zone is crisscrossed by roots, openings left by decayed roots, and animal and worm burrows, which allow the precipitation to infiltrate into the soil zone. Water can also evaporate directly into the atmosphere.
which area would have the highest salinity
Answer: high rates of evaporation
Salinity is the measure of amount of salt dissolved in the water. The area with a plenty of run off will have very low salinity as the run off will take away the surface particles might be containing salt in it. The area with high rates of precipitation will have very low salinity this is because of the fact that the rainfall will take away the salts present on the surface to other location because of water erosion.
The area with high rates of evaporation will have highest salinity because the water or other liquid components gets removed from the surface leaving behind all the solid sediments which may also include salts.
Which of these statements is true of offspring from organisms that reproduce asexually?
Offspring are genetically identical to the parent.
Offspring are genetically different from the parent.
Offspring have no features like the parent.
Offspring have some features like the parent.
First, to be able to answer this, you need to know the definition of asexual and sexual organisms. On a quick basis, sexual organisms need to parents, male and female, to make a child. Asexual organisms, on the other hand, only need one parent to have an offspring. Sexual organisms have a mix of both of their parents DNA. Asexual organisms are a replica of the parent.
So, the correct answer is:
Offspring are genetically identical to the parent.
Answer: The answer is "Offspring are genetically identical to the parent."
