People who climb Mount Everest—the tallest mountain in the world—often need to carry oxygen tanks. The oxygen tanks help them breathe at the highest elevations. What creates the need for extra oxygen?
Can you write a more detailed explanation of why climbers need oxygen tanks as they near the top of Mount Everest?
Answers
Explanation:
When people get to higher attitude the amount of gas molecules in the air
becomes limited, since that happens it means that people will need more oxygen to have the blood flowing to be steady, so that's why people will carry portable oxygen tanks.
Bonus- "This makes it harder to breathe because you need to inhale"
Explanation:
This is because, without extra oxygen, climbing Mount Everest is a very big risk. Mount Everest is located where there can be extreme weather, steep and icy slopes, also deep colds that drop to -41℃. So it is a very good idea to bring extra oxygen.

Beth wrote the following description of the life cycle of non-flowering, seed-bearing plants. Read her description and find the mistake.
"Non-flowering, seed-bearing plants go through four major stages in their life cycles. The first stage is when the plant is a seed from a cone. The second stage is when the plant sprouts out of the seed and the cones begin to grow. The third stage is when the plant is a seedling. The fourth stage is when the plant is a bigger seedling."
What statement corrects the error in Beth's report?
There are five stages in the life cycle of non-flowering, seed-bearing plants, not four.
The first stage is when roots will grow out of the seed and down into the soil.
The third stage is when the plant sprouts out of the seed and the flower grows.
The fourth stage is when the plant is an adult plant growing leaves and cones which produce more seeds.

identify each of the cell structures and their function: centrosomes, aster, equator, cleavage furrow, cell plate, kinetochore fibers, spindle, microtubules and cytokinesis
Answers
Answer: Interphase
Explanation:
aster- they hold the two centrioles at the two opposite poles, and help the spindle apparatus to position during nuclear division.
equator- it divides the planet into a northern hemisphere and a southern hemisphere.
cleavage furrow- is an indentation that appears in a cells surface when the cell is preparing to divide.
cell plate- a plate that develops at the midpoint between the two groups of chromosomes in a dividing cell and that is involved in forming the wall between the two new daughter cells.
kinetochore fibers- the main function is to generate load-bearing attachments of sister chromatids to spindle microtubules during cell division.
spindle- is used to ensure the chromosomes are positioned properly inside the cell during mitosis.
microtubules- they regulate cell growth and movement, as well as key, signaling events which modulate fundamental cellular processes.
cytokinesis- the process by which one’s self physically divides into two cells.

Does the pattern in a food chain support the conclusion that climate change is caused by human activity and deforestion? Why or Why not?
Answers
Answer: No, it does not directly.
Explanation:
The pattern in a food chain cannot directly support the conclusion that climate change is caused by human activity and deforestation, as food chains only describe the transfer of energy and nutrients between different organisms in an ecosystem. However, the impacts of climate change and deforestation can disrupt food chains and have cascading effects on ecosystems, which can ultimately lead to the extinction of certain species and the loss of biodiversity.
Human activities, such as burning fossil fuels, deforestation, and agricultural practices, contribute to the emission of greenhouse gases, which trap heat in the atmosphere and cause global temperatures to rise. This increase in temperature can have a range of effects, including changes in precipitation patterns, rising sea levels, and more frequent and intense extreme weather events.
These changes can disrupt the habitats and food sources of many species, causing declines in their populations and even extinction in some cases. For example, deforestation can lead to the loss of habitat for many species, including those that are important components of food chains. Additionally, changes in precipitation patterns can affect the growth of plants and the availability of food for herbivores, which can then impact the populations of predators that depend on these herbivores for food.
In summary, while the pattern in a food chain itself does not provide direct evidence for the causes of climate change, the disruption of food chains and ecosystems due to human activities and deforestation can contribute to climate change and its impacts.
No, a food chain's pattern does not conclusively prove that human activity and deforestation are to blame for climate change.
The pattern in a food chain does not necessarily prove that human activity and deforestation are to blame for climate change. Natural processes, greenhouse gas emissions, changes in land use, and other factors are only a few of the many influences on the complex phenomenon known as climate change. While human actions like burning fossil fuels can raise greenhouse gas concentrations and deforestation can lessen carbon sinks and release stored carbon into the atmosphere, these factors cannot simply be attributed to the pattern in a food chain.
A thorough examination of the diverse scientific facts and evidence from numerous disciplines, such as atmospheric sciences, climatology, and earth sciences, is necessary to comprehend and handle climate change.

Scientists observed some fossils of the early ancestors of camels. Using the fossils they obtained, they prepared a phylogeny chart for camels. Based on this chart, what can you conclude about the relationship between modern camels (Camelus) and Aepycamelus?
Answers
Answer:
It is clear from a camel's phylogenetic tree that Aepycamelus and contemporary camels (Camelus) are closely related. The evolutionary links between several groups of creatures are displayed in phylogeny charts or evolutionary trees. It is based on traits that extinct species shared and fossils from those species.
Explanation:
One of the earliest known members of the camel family is known as Aepycamelus, and it is thought that Aepycamelus gave rise to contemporary camels (Camelus). The graph most likely demonstrates the close relationship between Aepycamelus and contemporary camels, as well as their shared progenitor. This information leads us to the conclusion that contemporary camels and Aepycamelus have a tight evolutionary connection and are related genetically.

4. What happens to a plant with low turgor pressure?
5. What must a seedling do in order to emerge through the soil?
6. Compare the turgor pressure of a cell to a water balloon.
7. If flowers begin to wilt, is there anything that can be done to save them?
Answers
Answer:
. How do forces affect both plants and animals?
Gravity affects everything, both living and non-living things. For animals on Earth (like you), gravity determines which direction is down and up.
. What forces act on or within plants?
Forces, including gravity, are constantly acting upon plants and cause them to be in motion. Plants can be in motion just like we are in motion.
What is turgor pressure?
urgor pressure is the force within the cell that pushes the plasma membrane against the cell wall
What happens to a plant with low turgor pressure?
Turgor pressure in plants. Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth.
What must a seedling do in order to emerge through the soil?
he most common pattern is where the cotyledons are raised above ground as the seedling emerges. The seedling forms a hypocotyl hook that pushes through the soil.
Compare the turgor pressure of a cell to a water balloon.
When the turgor pressure in a cell is high, it will be swollen and firm from the water inside.
If flowers begin to wilt, is there anything that can be done to save them?

Which is not a characteristic of an early succession plant?
A.) produces lots of seeds
B.) the seeds germinate best in shade
C.) small in size
D.) short-lived
Answers
Early succession plant has a characteristic of producing a lot of seeds, smaller size and short lived. Therefore, the correct statements are option A, option C and option D.
What are early succession plants?Early succession plants are plants that quickly adapts in areas that have been recently cleared and have harsh environments. These plants can easily grow in areas having low soil fertility, lack of water and high exposure to sunlight.
These plants produce a lot of seeds, are smaller in size, and short lived. High reproductive capacity, fast growth, tolerance to harsh conditions, short life cycles are other characteristics of an early succession plant.
Weeds like dandelions, annual rye grass and shrubs like fireweed are some of the examples of early succession plants. These plants have also the ability to fix nitrogen in the soil to improve the soil quality for plant growth. However, their seeds do not germinate best in shade.
Therefore, early succession plants produce lot of seeds, smaller in size and short lived.
