If a plant looks purple, which light color is causing the plant to photosynthesize?
Green
O Purple
O Blue
Red
Answer:
Purple
Explanation:
To perform photosynthesis, violet light is the most important color, and it's from these wavelengths that plants get most of their energy. The reason for this is because out of the visible spectrum, red light is the longest wavelength light that the photosynthesis process can use, but it has the least energy
describe enzyme in washing
Answer:
Enzyme washing or "bio stoning" is a textile manufacturing technique in which cellulase enzymes are applied to denim. As with traditional stone washing, the intended effect is a faded appearance and softer feel. Because the technique relies on biotechnology, enzyme washing is considered an example of textile bio-processing.

Cellular respiration release CO2 and photosynthesis absorbs CO2. These two reactions are part of which biogeochemical cycle?
A. Carbon cycle
B. Water cycle
C. Phosphorus cycle
D. Nitrogen cycle
Answer:
A
Explanation:
A. Carbon cycle
Cellular respiration is the metabolic reaction that occurs in the cells of organisms. Cellular respiration and photosynthesis both add carbon dioxide to the biogeochemical cycle. Thus, option A is correct.
What is a biogeochemical cycle?The biogeochemical cycle is the process that transfers and moves the abiotic chemical factors through the various spheres of the earth. It includes carbon, water, nitrogen, phosphorus cycle, etc.
The process of cellular respiration releases carbon dioxide as the waste gas into the atmosphere that gets consumed by the plants to make energy that gets eaten by the organism that again releases the carbon dioxide. This cycle of carbon goes on from the producer to the consumer in the ecological chain.
Therefore, cellular respiration and photosynthesis contribute to the carbon cycle.

How do geologists study direct evidence of Earth’s interior?
by collecting drill core samples of Earth’s crust
by measuring seismic wave activity
by analyzing how living things survive
by recording changes in climate patterns
Answer: A
Explanation: E2022
Geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option, as the seismic waves are waves of energy that travel through the earth's interior.
What are seismic waves?Geologists use various techniques to study the Earth's interior, but one of the most important is the measurement of seismic wave activity. Seismic waves are generated by various sources, such as earthquakes, volcanic eruptions, and human-made explosions. The waves travel through the earth's interior and can be detected by seismic instruments such as seismometers. Seismic waves come in two main types: body waves and surface waves. Body waves are waves that propagate through the earth's interior, while surface waves travel along the earth's surface. Body waves are further divided into two types: P-waves and S-waves.
Hence, geologists study direct evidence of Earth's interior by measuring seismic wave activity, which is the second option.

Ddt was widely used as a pesticide for 20 years. Its use was banned after studies showed severe side effects were evident in humans, the environment, and animals as a result of ddt. Which reason best explains why the side effects of ddt were so harmful?.
Answer:
One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.
Which compound can only be made if it has access to magnesium ions?
Answer:
Hope it helps
Explanation:
Green plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.Plants need minerals for healthy growth. They are absorbed through the roots by active transport as mineral ions dissolved in the soil water.Magnesium ions and nitrate ions are needed by plants. A plant will not grow well if it cannot get enough of these ions, and it will show symptoms of mineral deficiency. Fertilisers are used to replace minerals used by plants.
Nitrogen fertilisers - such as ammonium nitrate and ammonium phosphate - provide plants with water-soluble sources of nitrogen that they can absorb through their roots. They allow farmers to increase the yield and quality of their crops. However, overuse can cause problems. Eutrophication happens when excess nitrate (or phosphate) enters rivers or lakes from fields. This can lead to the death of fish and other aquatic animals.

Identify the term that best describes the process of collecting a tissue sample from the endocervix and the exocervix with a sampling device that is placed directly into a liquid fixative instead of being spread onto a glass slide.
The term that is used to describe the process of collecting a tissue sample from the endocervix is liquid-based Pap.
What is endocervix?Endocervix is the inner part of the cervix which links the cervix to the uterus.
To examine the cellular structure of the endocervix, a pap smear examination is carried out.
When the pap smear is placed directly into a liquid fixative instead of being spread onto a glass slide it is called a liquid-based Pap.
