Answer:
Looking at the sky during night is always an amazing scene. It takes our breath away, every time when we see the night sky with countless stars twinkling, full moon and planets. I always wished I reach those far planets travelling in space. The only way I can fulfill my dream is to become an astronaut. Astronaut is a person who is trained to travel in a spaceship to go to outer space. If I were an astronaut, I wish my first mission will be to the moon. However, I will have to undergo a very strict training to survive in space We all have seen the training videos of astronauts in DISCOVERY channel where they even undergo underwater training. Life in space will be different with zero gravity and so we will experience zero weight and will float freely. Wow!!!! that seems to be an exciting thing. But how we will eat and drink?
Explanation:
if you want to imagine about space
first of all you need to clear your mind
and you need to concentrate your mind on the space and imagine .if you are not getting anything then drink some water and repeat the same process . I hope you will be successful to imagine space ..
best of luck

The small intestine breaks down compounds, while the large intestine absorbs water
The small intestine stores food waste, while the large intestine removes food waste.
The small intestine takes In nutrients, while the large intestine eliminates waste.
The small intestine excretes Juices to digest food, while the large intestine absorbs nutrients.
Answer:
The small intestine takes in nutrients, while the large intestine eliminate waste.
Explanation:
Small intestine doea not break down compounds, it is stomach's job. It is good at absorbing nutrients. Large intestine does not usually absorb nutrient, it absorbs water and eliminate waste. So combine all of this, the best answer is the third one.❤️
The Trans-Pecos ecoregion in the western portion of Texas
receive less than 38 cm of rainfall a year and has little soil due
to overgrazing by farm animals. What catastrophic event is
most likely the cause the most weathering and erosion in the
least amount of time in this ecoregion?
1.Wildfire
2.Earthquake
3.Flood
4.Tornado
Answer:
3.Flood
Explanation:
Flood is the catastrophic event which is the main cause of the most weathering and erosion in the least amount of time in this ecoregion because there is no vegetation present in this region and the soil is vulnerable for erosion. Flash-flooding and rapid runoff are agents of erosion in the Trans-Pecos ecoregion of Texas whenever the rainfall occurs. Vegetative is very important for preventing soil erosion so the people of this region has to stop overgrazing in this area in order to avoid more erosion of the soil.

In an ecosystem, what are some living and nonliving things that affect the ecosystem?
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.
Explanation:
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. Some examples of living things are organisms such as plants, animals, fungi, and bacteria.
Define these types of relationships (symbiosis).
a. mutualism -
b. commensalism-
c. parasitism -
d. predator/prey -
e. competition -
Answer:
mutualism -Both species benefit
commensalism- One species lives with, on, or in another species (the host). The host species neither benefits nor is harmed from the relationship. The species that lives on the host is benefited.
parasitism - One species (the parasite) lives with, on, or in a host species, at the expense of the host species. Unlike in predation, the host is not immediately killed by the parasite, though it may sicken and die over time.
predator/prey -One species (the predator) hunts and kills another species (the prey)
competition -The struggle among organisms for the same limited resources in an ecosystem

Complete the table below to show the difference between active and passive transport. Put a “X” in boxes that satisfy the statement.
Answer:
Active transport:
requires energymolecules move from low to high concentration sidesNa+ and K+ move by active transportSimple diffusion:
molecules move from high to low concentration sidesmolecules pass between lipids small non-polar and polar moleculesFacilitated diffusion:
molecules move from high to low concentration sidesinvolves channel proteinsmove large moleculesExplanation:
Simple Diffusion is the pathway of only small molecules that freely move through the membrane by momentary openings produced by the lipids' movements. Diffusion is a slow process that requires short distances and pronounced concentration gradients to be efficient. An example of diffusion is osmosis by which water is the transported molecule. Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient. Glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.Simple diffusion and facilitated diffusion are both passive transport processes because they only depend on electrochemical gradients, so they do not need any energy to occur.
Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen. Molecules move from the lower concentration side to the higher concentration side of the membrane. Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential. An example of molecules moved by active transport are the Na and K.In Active transport, molecules or ions move against the concentration gradient by using energy from ATP.
What is Membrane transport?The transfer of molecules across the plasma membrane into or out of the cell.
There are two types of membrane transport,
1. Passive transport:
When molecules move along the gradient. It can be of two types,
Simple diffusion (via phospholipids)Facilitated diffusion (via channel protein)2. Active transport:
When molecules move against the concentration gradient, they require energy. Energy is given by ATP.
Therefore, in Active transport, molecules or ions move against the concentration gradient by using energy from ATP.

Read the following scenario to answer the following question. Avian influenza is a viral infection with few damaging effects that naturally occurs in wild birds. However, avian influenza is highly contagious and can quickly kill domesticated birds. Some human influenza viruses are similar to the avian influenza. People infected with avian influenza develop typical flu symptoms (fever, cough, muscle aches). However, symptoms may become more severe and life-threatening. If avian influenza evolves into a form that is easily transmissible from person to person, a global pandemic of widespread human death might occur. Which cells would be active during an immune response to a viral infection
Answer:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines.
Explanation:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines are the cells that are active during an immune response to a viral infection. These cells attack on the virus that is responsible for the infection. If the immune system is strong and these cells kills all viruses then no viral infection occurs while on the other hand, if these cells can't control the virus, the virus will cause infection in the body so these cells plays a vital role in prevention of infection.

state one adaptation of nephron in the kidney of a desert mammal
Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.
