Which animal is often used to model human body systems?
pig
rabbit
cow
sheep
Answer:
Pig
Explanation:
Rabbit is often used to model human body systems
Recent advancements in mammalian and rabbit genomic studies have reaffirmed the rabbit as a prototype genetic system. They have genomes that are almost identical in size and are thought to have split 80 million years ago from a common origin.
Rabbits have counterparts to almost all human genes.

ayuda porfa :c
Answer:
La gestión del agua es importante ya que ayuda a determinar las expectativas futuras de riego. La gestión del agua es la gestión de los recursos hídricos bajo políticas y regulaciones establecidas. El agua, que alguna vez fue un recurso natural abundante, se está convirtiendo en un bien más valioso debido a las sequías y el uso excesivo.
Explanation:
La gestión de los recursos hídricos es un tema muy importante desde varios ángulos, como el desarrollo de masas de agua para el futuro, la protección de las masas de agua disponibles de la contaminación y la sobreexplotación y la prevención de disputas. Una cuestión primordial es el agua: su disponibilidad, calidad y gestión.

do you think your heart plays the biggest role in the process of getting your blood become rich in oxygen and transporting materials gases and other molecules to and from the different parts of the body?
WHY DO YOU THINK SO?
Yes. Absolutely. Without heart, no one can live. It helps in pumping of oxygen rich blood to all body cells and tissues. It also helps in transportation of various materials like potassium, sodium, calcium etc. in our body. The main function is that it helps in excretion of wastes.
Since blood is liquid and heart pumps it, the waste materials like CO2, gets diffused and becomes impure blood. Then it is taken to lungs for purification and again reused.
So, heart actually helps us indirectly in many ways.

What is the answer to the question 3
Answer:
D. the natural resources available in an ecosystem.
Explanation:
Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.

Underground mining removes minerals from deep in the earth. Miners use blasting to separate the "waste" from the mineral deposit. Which statement best describes
an environmental consequence of this process?
O Underground mining activities often cause noise pollution
O Acid mine drainage kills plants and animals around the mine.
O High salinity of wastewater reduces soil fertility and vegetation
O Soil is removed by the force and pressure of the drilling process.
Answer:
Acid mine drainage kills plants and animals
Explanation:
took the quiz :)
The correct answer as to the environmental consequence of using blasting to separate wastes from mineral deposit is noise pollution. The statement that best describe the process, therefore, would be that underground mining activities often cause noise pollution.
Blasting simply means to break something apart or to blow up something. When blasting is associated with mining, it usually involves the use of explosives. These explosives make loud noise when they are used in blasting.
Hence, blasting can be said to be a source of noise pollution to those staying close to the mining area.

Explain how increasing the temperature increases the rate of the reaction
Explanation:
The more the temp rises the more energy it generates. In a reaction there are molecules in which they bounce around and collide in order to form the reaction. With more energy being introduced the molecules will speed up and collide more often than what the speed was before which directly relates to why the rate of a reaction is increasing.

What is the function of a chloroplast? A. Gamete production B. Cellular respiration C. Fermentation D. Photosynthesis
Answer:
So i had these notes from a couple of days ago and I’d like to help u out
Explanation:
Photosynthesis
Carbon dioxide enters through the leaf which contains small pours called stomata. The carbon dioxide then enters the cells of the leaf.
Inside the cell carbon dioxide diffuses into the chloroplasts. Where photosynthesis takes place
Chloroplasts use energy from sunlight to transform carbon dioxide and water into sugar and oxygen.
The light reactions
Inside chloroplasts there are these flat membranous sacs called thylakoids.
Thylakoids are the place were light energy is converted into chemical energy in the first phase of photosynthesis the light reactions.
Photosystems
Photosystems are large complexes of proteins and chlorophyll (capture light energy)
Electron transport chain
This chain connects the two photosystems.
Electron carrier
These shuttle (transport that is mainly between 2 things going back and forth) electrons from one photosystem to another
Photosystem
One of the photosystems are used to absorb energy which then excites the electrons that then enter the electron transport chain. These electrons are replaced with electrons stripped from water creating oxygen as a byproduct.
The electrons on the chain
The energised electrons are flowing down the electron transport chain releasing energy that is used to pump hydrogen ions
Hydrogen ions
An atom or molecule that has a net electrical charge due to the loss of one loss or one gained electron.
The electrons on the chain
As the hydrogen ions get pumped out they are then absorbed into the thylakoids
In the photosystem on the right light energy excites electrons and this time the electrons are captured by an electron carrier molecule also known as NADPH
The high concentration of hydrogen ions inside the thylakoid powers ATP synthase producing ATPS the light reactions in the thylakoid have produced two products, ATP and NADPH.
Those two products then power the production of sugar in the Calvin cycle
THE CALVIN CYCLE (C3 Cycle)
The Calvin cycle takes place outside the thylakoids in the stroma (the thick fluid of the chloroplast).
At the beginning of the cycle
carbon dioxide molecules combine with molecules called rubp the resulting molecules go through a series of reactions powered by ATP and NADPH from the light reactions sugar molecules known as g3ps are produced.
G3ps
Most of the g3ps molecules are rearranged back into rubp’s that begin the calving cycle again.
The important product
Then some of the left over g3ps is the remaining g3p sugar, some g3ps are used to build glucose which can then combine into starch or even cellulose
Bits of left over g3ps are also able to break down by cellular respiration, which uses oxygen in the plants own mitochondria, this generates ATPS that can power other work of the plant.
The left overs
Excess oxygen diffuses out of the leaf through the pores while more carbon dioxide goes into the leaf pores.
