Explanation: because it occurs in the nucleus
what would happen if DNA replication it didn't occur?
Answer:
If DNA replication does not occur, then the cell cycle (Mitosis and Miosis) will not proceed to the next stage and the subsequent division will not happen. It will lead to cell death.
Simply put, without cell replication, cells can’t divide and they eventually die out.

Importance of soil pollution
Answer:
Besides air pollution, four other important types of pollution are soil, water, waste, and noise pollution -D.
Noise pollution comes from being overly loud compared to other species. Humans create a lot of noise pollution in cities where there is a lot of things going on and with that we create a lot of damage to the environment.
Explanation:Hope it's helps you ! : )
Answer:
Soil pollution causes a chain reaction. It alters soils' biodiversity, reduces soil organic matter and soils' capacity to act as a filter. It also contaminates the water stored in the soil and groundwater, and causes an imbalance of soil nutrients.

Many of the rocks of the canyon wall
appear as horizontal bands. What do the
bands indicate about the way the rocks
formed? PLEASE ANSWER QUICK
Many of the rocks in the canyon wall the horizontal bands originate from erosion in their formation.
The hypotheses about the formation of canyonsThe hypotheses about the formation of canyons revolve around the movements of tectonic plates and the uplift of certain areas, that is, when a place is “lifted” by the force of tectonism.
With this information, we can conclude that many of the rocks in the canyon wall the horizontal bands originate from erosion in their formation.

The La Brea Tar Pits in Los Angeles are the site of millions of fossils from the ice age. Woolly mammoths, giant sloths, dragonflies, and other plants and animals from this era have been found in these pits.
Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angeles today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. Why do you think this is the case? What can scientists learn about Los Angeles’ climate history by studying the specimens found in these tar pits?
Answer:
231 species
Explanation:
More than one million bones were recovered in 1906. These bones represented 231 species of vertebrates and there were 234 species of invertebrates.
Los Angeles climate is relatively stable for over 50,000 years. The fossils of more than 180 insects were preserved in La Brea Tar Pits. The climate warming probes a link for evolution of Ice Age predators.
Explanation:
Mammals like sabertooths and mammoths both are extinct because Its reliance on large animals has been proposed as the cause of its extinction, along with climate change and competition with other species, but the exact cause is unknown.

In which stage of the cycle of a flowering plant does the plant produce seeds through pollination?
Answer:
maybe fertilisation
Explanation:
When the pollen reaches another flower, it travels to the ovary where it fertilises the egg cells to make seeds. This process is called fertilisation. These seeds are scattered by animals or the wind.
Answer:
I believe it would be the reproductive stage. In this stage of life, the plant begins to flower, aswell as fertilize and then produce the seeds.

Explanation:
A population of fish lived in a large lake. During a storm, a huge landslide occurred, bringing a large amount of land into the lake and splitting the lake into two bodies of water. Over many years, the fish population in each body of water evolved. The two fish populations can no longer breed together.
Is the speciation above an example of allopatric speciation or sympatric speciation? Explain how you know by referring to the definition of each.
Answer: Allopatric speciation
Explanation: Because in allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.
I searched it up and both don't fit this 100% so I am kinda just making a guss because the first part on this sounds right but the 2nd part doesent and on the other one the first part sound wrong but the 2nd part sounds correct.
Sorry if its wrong.
The given example shows allopatric speciation, because due to a storm, a huge landslide occurred, bringing a large amount of land into the lake and splitting the lake into two bodies of water.
What is allopatric speciation?A period of geographic separation causes groups from an ancestral population to diverge into distinct species in allopatric speciation. Without any geographical separation, groups from the same ancestral population diverge into distinct species in a process known as sympatric speciation.
While parapatric or sympatric populations live in the same habitat, allopatric populations are physically isolated from one another.
Therefore, while sympatric species share a single ecological niche, parapatric populations occupy different environmental niches and are thus divided by ecological variables.

Which of these does NOT explain why humans and other mammals breathe through lungs, unlike amphibians and other animals that take in oxygen through simple diffusion?
A. Large animals need more oxygen than small ones.
B. Oxygen can only pass through a constantly wet membrane.
C. Mammals have fewer cells than other types of animals.
D. Warm-blooded animals need a lot of oxygen to regulate their body temperatures.
Answer: B
Explanation: Frogs have a moist, permeable skin, which can transfer gasses such as carbon dioxide and oxygen. Humans have dry skin that is impermeable to gas exchange, so almost all gas exchange takes place in the lungs. This means human lungs must be more efficient than frog lungs
Answer:
B
Explanation:
it is so due to osmosis because molecules of oxygen can move through a semi permeable membrane or a permeable membrane and wet membrane is an example

Answer:
plants For example, phototropism is the plant's response to stimulus, i.e. sunlight. A plant hormone “auxin” keeps the plant's direction towards the sun by activating the growth in a particular part of a stem. Similarly, gravitropism in plants responds to the stimulus, i.e. gravity

Darwin’s finches have different beaks in terms of size and shape to be able to eat different food sources like insects, nectar, and seeds. Cactus finches have longer, more pointed beaks to probe cactus flowers compared to their relatives, the ground finches.
If a plant disease killed a large portion of the cacti on the Galapagos islands, what would the future populations of finches look like in terms of beak size and shape? Use your knowledge of natural selection to determine which option is most likely.
A. Cactus finches would compete for food with ground finches and exhibit competitive exclusion, so the beaks of future generations would be similar to whichever finch outcompetes the other.
B. Ground finches would survive and pass on their shorter and wider beaks, so there would be a higher proportion of finches in future generations that have short and wide beaks.
C. Ground finches would survive and pass on their beaks, but they would mate with the remaining cactus finches, creating a new hybrid that is somewhere between short versus long and narrow versus wide.
D. Cactus finches would compete for food with ground finches and exhibit resource partitioning, so the beaks of future generations would not change.
Answer:
The Answer should be B
Explanation:
The Knowledge of natural selection to determine which option is most likely Ground finches would survive and pass on their shorter and wider beaks, so there would be a higher proportion of finches in future generations that have short and wide beaks.
What is natural selection and example?
Natural selection is the procedure in nature by which organisms sufficiently adapted to their environment survive and replicate more than those less adapted to their environment.
For example, treefrogs are sometimes eaten by snakes and birds.
