What is Respiratory System?The respiratory system is the network of organs and tissues which helps with breathing that includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system. They work together to move oxygen throughout the body and to clean up waste gases like carbon dioxide.
Respiratory system consists of following parts like
Nose--> Mouth--> Pharynx --> Larynx --> Trachea --> Bronchi --> Bronchioles --> Alveoli
The respiratory system has many functions others than inhaling (breathe in) and exhaling (breathe out), it:
It allows talking and smelling.It warms the air to match the body temperature and moisturizes it to the moisture level the body needs.It transports oxygen to the cells in your body.It removes waste gases, including carbon dioxide, from the body when you exhale.It protects the airways from harmful substances and irritantsThus, following are the parts of Respiratory system:

Which organism carries out autotrophic nutrition
Answer:
Autotrophs is the answer
Example : plants
Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.
Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.
Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

in gel electrophoresis, a loading dye is usually added to the sample of dna to be loaded in the wells of the gel. why would this be important?
Answer:
Gel loading dye is typically made at 6X concentration (0.25% bromphenol blue, 0.25% xylene cyanol, 30% glycerol). Loading dye helps to track how far your DNA sample has traveled, and also allows the sample to sink into the gel. ... It is important to use the same running buffer as the one used to prepare the gel.

what organelle processes and sorts proteins to be shipped
Answer: The Golgi apparatus
Explanation: The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell.
The organelle that processes and sorts proteins to be shipped is the Golgi apparatus. The Golgi apparatus is a stack of flattened sacs that is located near the nucleus of the cell.
It is responsible for processing and sorting proteins that have been made by the endoplasmic reticulum. The Golgi apparatus modifies proteins, packages them, and then ships them to their final destinations.
The Golgi apparatus has three main functions:
Modification: The Golgi apparatus modifies proteins by adding sugars, phosphates, and other molecules to them. This modification changes the properties of the proteins and makes them more functional.
Sorting: The Golgi apparatus sorts proteins into different vesicles. These vesicles are then transported to different parts of the cell, where the proteins are used.
Shipping: The Golgi apparatus ships proteins to different parts of the cell by fusing the vesicles with the cell membrane.

A closed, rigid container with a given mass of helium gas is heated until the temperature is doubled.
Which of the following statements is TRUE?
A
The pressure of the gas is halved, because temperature and pressure is inversely related
B
The pressure of the gas also doubles, because temperature and pressure are directly related
C
The pressure of the gas is unchanged, because helium gas is lighter than the air outside the container.
D
The pressure of the gas is unchanged, because there is no relationship between temperature and pressure.
Answer:
i think the answer is B
Explanation:
Rabbits and sheep both graze on shrubs, grasses, and other plants. The sharp rise in the population of rabbits in a region may result in a shortage of plants for sheep to graze upon.
This relationship between sheep and rabbits is an example of _______.
A.
parasitism
B.
predation
C.
commensalism
D.
competition
The answer is D) competition.
We can see from the problem that the two animals are competing with one another. As the number of rabbits increases, the competition between the food source increases. This is why predators are important for the environment, as the level out the playing field for both animals.

What evidence of climate change on continents supports the theory of continental drift?
signs that glaciers existed in South Africa
similar coal fields on different continents
change in atmospheric temperature over time
same animal fossils found on different continents
Answer:
A
Explanation:
Edge2022
The evidence of climate change on continents that supports the theory of continental drift is similar coal fields on different continents. Hence option B is correct.
What is continental drift theory?The theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which began to break apart around 200 million years ago.
This idea was first proposed by German scientist Alfred Wegener in the early 20th century, who noticed the striking similarities between the coastlines of Africa and South America.
Coal is formed from the remains of plants that lived millions of years ago, and its distribution can provide clues about how continents were once connected.
Coal fields found on different continents that match in age and composition indicate that the continents were once joined together in a larger landmass.
This supports the theory of continental drift, which states that the continents were once part of a single supercontinent that later broke apart and drifted into their present positions.
This evidence suggests that coal-forming swamps once existed in locations that are now separated by oceans and that these locations were once connected.
Hence option B similar coal fields on different continents is correct.

What is fertilizer?
Outside matter added to the ground to help plants grow
Oxygen and water added to the ground
Inorganic matter
Nitrogen-fixing bacteria in the ground
Answer: 3
Explanation:
Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.
