Among the different forms of electromagnetic radiation emitted by the sun, which form is absorbed by plants for photosynthesis?.
Answer:
visible light is the em radiation absorbed by plants for the photosynthesis process.
The form of electromagnetic radiation that is absorbed by plants for photosynthesis is known as visible light. This is also known as photosynthetically active radiation (PAR).
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
Visible light lies in the visible spectrum of wavelength from 400 to 700 nm. This visible spectrum is a system where we study the properties of light. This spectrum defines the relationship between energy and wavelength.
Therefore, the visible light or visible spectrum is the form of electromagnetic radiation that is absorbed by plants for photosynthesis.

Concrete has a density of 2.30 grams per centimeter cubed. What is the
mass of a concrete block in kilograms that is 1000.Ocm x 1000.Ocm x 15.0
cm? *
Answer:
Explanation:
density=2.30 g/cm^3
volume=1000.0 cm*1000.0 cm*15.0 cm=15000000
now we know that
d= m/v
therefore
m=d*v
m=2.30*15000000
m=34500000 g
now we have to convert grams into kg
1kg=1000 g
34500000 g=34500000/1000
34500000 g=34500 kg

Why is biology so fun?
Answer:
Biology is a fascinating subject in and of itself. It has been my favorite subject to read about and study since I was an incredibly young child. Biology is unique in its complexity and the way living things interact with one another and with their environment. It is fascinating to consider that many of Earth's rocks and minerals came from living things. Chalk and limestone are the remains of small aquatic creatures, particularly shellfish, which died and fell to the seabed, where they were buried and compressed into rock. A limestone or chalk that has been subjected to elevated temperatures and pressures, for example, is metamorphosed into marble. The fact that flints started out as sponges is less well known. Mineralogy and geology on Earth would be quite different if there were no living things.

How does nondisjunction cause chromosome number disorders.
Answer:
Disorders of chromosome number include the duplication or loss of entire chromosomes, as well as changes in the number of complete sets of chromosomes. They are caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis.
Explanation:
Based on this picture, how do you think a DNA molecule makes a copy of itself? (Hint: Look at the bottom two “rungs” of the ladder.)
The figure is not found here but DNA makes copies of itself by a semiconservative process. It is part of DNA replication.
What is DNA replication?DNA replication refers to the process by which a DNA molecule multiplies to produce two identical DNA molecules.
The DNA molecule is a double helix that may be considered a ladder, where pairs of nucleotides are the ladder's rungs.
DNA replication is semiconservative because the new DNA molecules have a new DNA strand and one original strand.

1. Describe what DDT is and how does it impact the food web. 2. Do you think humans health can be affected by hazardous bioaccumulates in an ecosystem? Make sure you explain using a statement from the reading. 3. Do you think DDT is the only bioaccumulate that can affect the food webs of an ecosystem?
Answer:
1. DDT may alter the central nervous system of the animals living in an ecosystem contaminated with this synthetic insecticide, thereby affecting their food relationships
2. Yes, indeed it has been shown that the incidence of deaths by cancer is significantly higher in areas where DDT is used as an insecticide. Moreover, it also been shown that this compound alters the endocrine system of most animals.
3. DDT is a synthetic biomolecule insoluble in water and persistent in the environment, and it is therefore a severely hazardous formulation. Persistent organic pollutants include synthetic organochlorine pesticides (for example, DDT), industrial chemicals, especially toxic polychlorinated biphenyls such as those used in insulating fluids for transformers and capacitors and industrial hazardous substances, including polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF).
Explanation:
Dichlorodiphenyltrichloroethane (DDT) is an organochlorine substance originally used as an insecticide, which became infamous due to its environmental impacts. In 1972, the US banned the use of DDT; however, there are countries that still use it as an insecticide for the control of mosquitoes in endemic malaria areas.

Although the genes that cause LHON are found in cells throughout the body, LHON especially affects specific cells in the eyes and heart. Why do you think that tissues with these cells are among the first to fail as a result of defective mitochondria? How could a mitochondrial defect be related to vision and heart problems?Cite evidence
Answer:
Leber’s hereditary optic neuropathy (LHON) is defined as a disorder caused by a mitochondrial mutation that affects the visual and heart cells.
A defective mitochondria is the primary cause of the LHON because it causes mtDNA is involved in the encoding of ubiquinone oxidoreductase (subunits of NADH) that is the first complex of the electron transport chain. So, any defect or mutation in mtDNA causes neuronal defects.
Mitochondrial defect due to mutation in amino acid exchanges in ubiquinone oxidoreductase affects optic nerves causing loss of retinal ganglion cells (RGCs) and their axons that leads to vison loss.
Mitochondrial biogenesis is the process in which mitochondrial ATP produced, and ATP transfer to heart and defect in mitochondrial biogenesis causes defect in heart cells.

What is the most likely result of the wave being transferred from the rock/soil to the air? Group of answer choices
Answer:
Propagation waves that can alter the winds and generate tornadoes, even these waves can also propagate over water surfaces and generate large masses of water that are expressed in forms of giant waves or tsunamis.
