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.

Salt marshes typically sit above the high tide mark this is false.

They haven't positioned the excessive tide mark but instead withinside the region. Because they are weak and have a low grip on them thus settling bove will cause loss.

This marsh habitat is an open ruled through those decreased flowers – there are, in fact, not often any bushes determined withinside the salt marsh.

Thus it is clear that Salt marshes typically sit above the high tide mark this statement is false.

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.

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

Answer:

Two estuaries are not alike because their characteristics are base on the local climates,freshwater that flow into it, water currents and the pattern of tidals.

Explanation:

Estuary refers to the area or region where fresh water a stream or river join and meet with salt water from ocean or sea. Therefore the fresh water from river then mix with the salt water from ocean and thus form what is called brackish water.

Two estuaries are not alike because they have different local climates, different fresh water that flow , different water current and different tidal patterns.

Answer:Estuaries are bodies of water and their surrounding coastal habitats are typically found where rivers meet the sea. Estuaries harbor unique plant and animal communities because their waters are brackish — a mixture of fresh water draining from the land and salty seawater.

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.

The figure is not found here but DNA makes copies of itself by a semiconservative process. It is part of 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.

Answer:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Weathering and erosion constantly change the rocky landscape of Earth.

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).

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.
