Answer:

Rainwater is very important in my area, we use it for crops, animals and for everyday essentials. It's collected in jars and kept stored, it can be filter then boiled to extract any bacteria. Then I usually sit it outside in the sun to grab the suns energy. This saves me a lot of money on utilities like my water bill for example. It's safe for everyone and poses no threat to the environment.

Explanation:

This is a natural alternative for anyone who loves nature and alkaline water

Imagine that y-axis of each graph describes the rate of photosynthesis. Which of the graphs represents the
astraxan [27]

Answer:

a. <u>A</u><u> describes the effect of light intensity on photosynthesis.</u>

Explanation:

In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.

The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:

  • carbon dioxide concentration,
  • ambient temperature
  • and light intensity

It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as <u><em>the intensity increases steadily, so does the rate</em></u>- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.

Beyond this point, either the supply of <em>carbon dioxide or the temperature</em> limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.

Can someone write the first paragraph
Katena32 [7]

Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D

How are the dark reactions dependent on the light reactions
andre [41]
Light-independent reactions (dark reactions). Light reactions need light to produce organic energy molecules. Dark reactions make use of these organic energy molecules.
