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.

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.

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.

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.

Explanation:

well of you use a cup to give a plant water you can measure how much it drinks

The measurable factors are A) How often a plant is watered, B) How much sunlight a plant receives, D) The actual number of new leaves on a plant.

Options (A) (B) & (D) are correct.

Measurable factors are those that can be quantified or expressed numerically. A) The frequency of watering can be counted and tracked over time. B) Sunlight can be measured in terms of intensity, duration, or light levels. C) "Seeing pretty leaves" is subjective and not quantifiable.

D) The actual number of new leaves is a concrete count, making it measurable. When studying or managing plants, it's essential to focus on quantifiable aspects, like watering frequency, sunlight exposure, and counts of observable changes, for accurate analysis and decision-making.

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.
