what are the limitations of the respiratory system?

Answers

Answer 1

Answer:

Having gills, or the ability of gills.

Explanation:

Our lungs can't filter out water and use the oxygen in the water, sadly.

And, we can't hold our breath for that long, compared to other mammals (the only way that we can hold our breath for a long time is if we breathe in pure oxygen).

Which of these zones of the ocean is most hospitable to life?
O A. Epipelagic
O B. Abyssopelagic
O C. Hadalpelagic
O D. Bathypelagic

Answers

Answer:

A.

Explanation:

The zones of the ocean which is most hospitable to life is the epipelagic zone. Thus, the correct option will be A.

What is the epipelagic zone?

The Epipelagic zone can be referred to as the uppermost layer of the ocean. Epipelagic zone is located between the surface and the 600 feet in depth of the ocean. The Epipelagic Zone is also known as the Sunlight Zone. It is the region of the ocean which sits on the continental shelf in the oceans.

Epipelagic zone is in this thin layer which the process of photosynthesis takes place. The epipelagic zone of the ocean only represents about 2 to 3% of the entire ocean zone, beyond this zone, light is too dim for the process of photosynthesis to occur. This is the reason why, the epipelagic zone is the most hospitable zone of the life in oceans.

Therefore, the correct option will be A.

A mutation that causes abnormal cell division can result in
1.) cystic fibrosis.
2.) clogged arteries
3.) sickle cell anerna aneria
4.) skin cancer.​

Answers

Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

So 4) skin cancer

The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.

What can happen if a mutation results in aberrant cell division?

Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. A tumour can form as a collection of malignant cells enlarges.

hence, skin cancer

Proteins are made from information found in genes, and proteins regulate a number of vital processes, including cell growth. Protein function can be altered by genetic alterations. Certain kinds of genetic changes to proteins result in healthy cells can become cancer.

Explain how Earth’s atmosphere affects solar radiation

Answers

Answer:

Explanation: Three atmospheric processes modify the solar radiation passing through our atmosphere destined to the Earth's surface. These processes act on the radiation when it interacts with gases and suspended particles found in the atmosphere.

The three main atmospheric components that absorb radiation are ozone, carbon dioxide, and water vapour. The sun's UV energy, which is detrimental to the majority of living organisms, is absorbed by ozone. Without the atmosphere's protective barrier, sunlight would cause our skin to burn.

What Earth’s atmosphere affects solar radiation?

29% of the solar energy that strikes the Earth is returned to space as a result of reflection, largely from clouds but also from other brilliant surfaces and the atmosphere itself. Approximately 23% of the energy entering the environment is absorbed by atmospheric gases, dust, and other particles.

Therefore, The solar radiation that enters our atmosphere and is directed toward the Earth's surface is altered by three atmospheric processes. When radiation interacts with gases and suspended particles in the atmosphere, several processes impact the radiation.

Answers

Answer:

to study earth's past climate

Answer:

Explanation:

Air bubbles and dust get trapped in ice as it forms. And the ice in some places, like Antarctica, has stayed frozen for over a million years. Scientists drill holes in the ice and remove ice cores. Each year's worth of ice forms a layer within the core.

The material trapped in ice layers gives information about the climate at that time. Scientists study the layers to learn about past temperatures and precipitation. They can learn how the amount of carbon dioxide in the atmosphere has changed over time. The layers also reveal when events such as volcanic eruptions have taken place.

Ecological success is valuable to understand, because it can change the biodiversity within an ecological community. Being able to teach a topic to a peer can demonstrate mastery! Explain the sequence of events that occur in secondary succession as you would to a friend who had not yet learned about the process.

Answers

Answer:

Secondary succession is a process in which a given area is disturbed, being re-colonized by other organisms following this process.

Explanation:

Secondary succession steps:

1- An area suffers a disturbance (e.g., fire, flood, earthquake, etc).

2-The process of disturbance destroys the food chain by removing primary producers (e.g., plants)

3- The vegetation grows back (i.e., first grasses and after higher trees). This process is known as recolonization  

The secondary succession can regenerate an ecosystem in less than 50 years after disturbance. The first species re-established during secondary succession are the animals capable of living in disturbed habitats.

Secondary succession refers to the re-grow of species and the establishment of new ones in areas where a perturbation occurred leaving fertile good soil.

---------------------------------

Succession is a term used to refer to colonization and subsequent changes.  

Colonization drives the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.

When talking about succession, we refer to changes produced in the composition and structure of communities after a perturbation.

When a perturbation occurs -like fires, floods, earthquakes- and removes part or all of the aerial vegetable life forms, we talk about secondary succession.

In secondary succession, after the perturbation occurrence, the soil remains good and fertile, carrying viable spores, seeds, and roots of surviving species.

With time these species emerge and re-grow, colonizing the area. Also, new species can arrive at the open space, establishing there for the first time.  

So, step by step,

1) A perturbation must occur in a community.

2) The perturbation damages or eliminates aerial parts of vegetable species. But the soil, which remains fertile, managed to protect seeds, spores, and roots of the species that used to live in these areas.

3) With time, these species regrow, and new species arrive in the area.

4) A new community emerges.

The prefix cyto- means “cell.” The suffix -logy means “study.” How does knowledge of these word parts help define cytology?

Answers

They help because cytology is the study of cells. Knowing that the suffix cyto means cell and the suffix logy means study we can conclude that cytology is the study of cells.

Cytology is the study of cells, and understanding the terminology's components aids in its definition. The Greek word "kytos" which meaning "cell" is whence the prefix "cyto" gets its name.

What is the meaning of the word ?

The Greek word "logia" (which meaning "study") is where the suffix "-ology" comes from. So, "cytology" can be defined as "the study of cells" when used collectively. The study of cell structure, function, and pathology is the focus of the biological field known as cytology.

Cells must be examined under a microscope and subjected to a variety of analyses to determine their structure and function. As a tool for identifying cancer cells, diagnosing diseases, and researching the impact of medications on cells, cytology is a crucial area of science.

Additionally, it is employed to research how cells form and behave intracellular communication in a living organism.

what is four the terrestrial planets​

Answers

Mercury, Venus, Earth and Mars

Answer:

Explanation:

Terresterial comes from the greek work "terra", which means Earth. So when you hear the word "terresterial " think that it means "like Earth". More specifically, it means that a planet is SOLID, like the Earth is. So, to figure out the answer to your question, let's list the planets starting with the ones closest to the sun and work out way out toward deep space. We can also describe each planet a bit as we list them.

Mercury - Closest to the Sun and, because of that, its very hot here. A lot of the ground on this planet is lava made of molten metal which is a liquid BUT there is also solid ground so it is terresterial. ✓

Venus - 2nd closest to the Sun. There is ground here, so it's terresterial. ✓

Earth - 3rd closest to the sun. There is solid ground here too so... Terresterial ✓

Mars - Also Solid. Terresterial ✓

Jupiter - Jupiter is made of Gas. If you went there, there would be nothing solid to walk on, but instead simply pass through it like it was a cloud. Therefore it is NOT terresterial

Saturn - Also a "Gas Giant" plant. (They are called gas giants because these planets are huge! You could fit 764 planet Earths inside of Saturn and over 1300 Earths could fit inside Jupiter!) Gas = NOT terresterial

Uranus - Another Gas Giant. Not terresterial

Neptune - The last of the gas giant planets and the furthest from the Sun. Again, its made of gas so its... not terresterial!

If you have trouble remembering the order, try memorizing this:

   "My   -   Very  -  Epic - Mother - Just  -  Served  -   Us   -   Nachos"
