Earth has a great variety of surface features that are caused by weathering and erosion. Which of the following describes a change due only to weathering?
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.

Why do temperatures on earth increase when the amount of carbon dioxide or methane in the earth system increases?
Answer:
The temperature increases when there is more energy in the room or wherever you are located
Explanation:
Hope this helps!
When the amount of carbon dioxide (CO2) or methane (CH4) in the Earth's system increases, it leads to an increase in temperatures on Earth due to the greenhouse effect. Here's how it works:
Carbon dioxide and methane are two examples of glasshouse gases, which trap heat in the atmosphere. Some of the sunlight that strikes the Earth's surface is absorbed and released as heat again.
Increased Greenhouse Effect: More heat is trapped in the atmosphere as glasshouse gases like CO2 and CH4 are present at higher concentrations. The amplified glasshouse effect describes this.
Global Warming: A phenomenon known as global warming is the outcome of the strengthened Glasshouse effect.
Climate Change: The Earth's climate system is significantly impacted by the rising temperatures brought on by global warming.

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

Copper is often found in wiring in homes. Why are wires not made of sulfur atoms, a nonmetal?
Wires are not made of sulfur atoms which is a non-metal as non-metals are generally bad conductors of electricity.
What are non-metals?
In a chemical reaction, non-metals, which are electronegative elements, frequently share or take electrons. Non-metals are characterized by physics as elements with a high band gap (activation energy), which makes them ineffective conductors of heat and electricity.
Non-metals also contain four or more electrons in their valence shell and are unattractive. Twenty of the known elements have been found to exhibit non-metallic characteristics.
Non-metals are extremely electronegative because they have more than four electrons in their outermost shell. When an ionic connection is formed, the non-metal ion receives a negative charge thanks to its electronegativity.
In a periodic table, as one moves from left to right, the number of electrons in the valence shell grows, increasing the non-metallic characteristic and decreasing the range of atomic radii.
Therefore non metals are bad conductors of electricity.

Why are no two estuaries alike?
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.

SUBMIT
B. it can compromise oxygen and nutrient delivery to muscles, which may cause cramps
Exercising right after eating can compromise oxygen and nutrient delivery to muscles, which may cause cramps. Therefore, option (B) is right.
What is exercise?Exercise is a physical activity that is performed to improve or maintain health and fitness, and typically involves structured and repetitive movements of the body. When you eat, blood flow is directed towards the digestive system to help with the absorption of nutrients from food. If you engage in exercise immediately after eating, blood flow is redirected away from the digestive system towards the working muscles, which can cause digestive discomfort and cramping due to a lack of oxygen and nutrients in the digestive tract.
It is generally recommended to wait at least 30 minutes to an hour after eating before engaging in exercise to allow for proper digestion and to avoid any potential discomfort or adverse effects on performance. Exercising right after eating is not likely to make your bones more susceptible to injury, cause you to sink in the water, or give you a bad headache.

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.

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.
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.
