The four organic molecules are listed below. Which ones do you get from the foods you eat? Check all that apply.
Carbohydrate
Nucleic Acids
Proteins
Lipids
Answer:
Carbohydrate, proteins, and lipids
Explanation:
The organic molecules that can be derived from eating foods are carbohydrate, proteins, and lipids.
Carbohydrates are general derived from starchy foods such as grains, proteins are derived from eating of foods that are rich in proteins such as meat, milk, etc, while lipids are derived from eating fat/oil-based foods such as butter, avocados, etc.
Nucleic acids are not derived directly from foods. They are monomers of proteins and hence, they are only derived from breaking down proteins.
Which answer below correctly identifies the type of change and the explanation for the separation of the iron with sulfur? physical change because even though a color change occured, each solid maintained its original properties, which could be seen as soon as the magnet was applied physical change because no temperature change was observed, which would be an indicator of chemical change chemical change because a color change was observed, which indicated that a new substance was formed chemical change because the results depended on the interaction of two substances
Answer:
[tex]\boxed{\mathrm{view \: explanation}}[/tex]
Explanation:
Physical change because even though a color change occured, each solid maintained its original properties, which could be seen as soon as the magnet was applied.
Speration of iron with sulfur will not change the properties of the metals, the magnet can be used to check. The color overall changes.
A physical change where each solid maintained its original properties when the magnet was applied is an explanation for the separation of the iron with sulfur. Therefore, the correct statement is option A.
What is physical change?The separation of iron from sulfur is an example of physical change. A physical change is a change in the physical state without the change in its chemical composition. The iron and sulfur can be physically mixed together and are both solids.
When a magnet is applied, the iron is attracted towards magnet, thereby, separating itself from the sulfur which is also a physical change, as it only causes a change in the appearance not in the chemical composition.
However, chemical changes are due to a change in the chemical composition of a substance that results in the formation of a new substance.
Therefore, physical change is an explanation for the separation of the iron with sulfur.

List the types of UV radiation
from least harmful to most
harmful.
Explanation:
UVC (100-280 nm)
UVB (280-315 nm)
UVA (315-400 nm)
The UV radiation from least harmful to most harmful is UV-A, UV-B, and UV-C. The correct option is A.
What is UV radiation?The sun and artificial sources, such tanning beds, both emit ultraviolet (UV) radiation, a type of non-ionizing radiation.
Although it helps humans in some ways, such as by producing vitamin D, there are also potential health hazards. The sun is a natural source of UV radiation for us.
UV rays come in three varieties: UVA, UVB, and UVC. Despite being the least powerful, UVA rays hasten the ageing of skin cells.
Sunburns and skin cancer can be brought on by UVB rays, which are a little stronger. Sun UVC rays are absorbed by ozone and do not go to the ground.
Thus, the correct option is A.

Explain why hormones are able to travel through the body but only affect certain cells.
Answer:
Hormones are able to travel the body but only affect certain cells because only those target cells have receptors for that particular hormone. Some hormones bind to receptors on the surface of target cells. Others enter the cells and bind to receptors in the cytoplasm or nucleus.
Explore the evidence supporting commonly held beliefs about proteins. 1. Gluten is toxic for everyone and should be avoided — no amount of gluten in the diet is considered safe. 2. Athletes and people who are very physically active need to eat a lot more protein than the average person. 3. Most Americans don't get enough protein in their diet
Answer:
Support the answer with the third point but mention not too take too much or they'd die.
Explanation:
Proteins are essential for the main physiological processes of life and perform functions in every system of the human body.
A protein’s shape determines its function.
Proteins are composed of amino acid subunits that form polypeptide chains.
Enzymes catalyze biochemical reactions by speeding up chemical reactions, and can either break down their substrate or build larger molecules from their substrate.
The shape of an enzyme’s active site matches the shape of the substrate.
The introduction of plastics in to the marine environment has also contributed to what other damages to planetary boundaries. Mark all that
apply
a. Biodiversity loss due to marine animals which are killed through entagling in or consuming plastic waste which reaches the ocean.
b. Biomagnification of mercury pollution in to the food chain through microplastics which absorb the mercury and are then
consumed.
c. An increase in ocean acidification through plastics leeching low pH contaminants in to the water.
d. An increase in carbon dioxide emissions which contribute to climate change through the use of fossil fuels in producing and
shipping plastic products.
Answer:
Option-A,B and D
Explanation:
Plastic pollution is one of the major threat to the ecosystem on Earth. The increased amount of plastic in the ocean has affected the aquatic ecosystem as it is the cause of the increased number of aquatic animals.
The animals consume the floating plastic of the ocean or get entangled in plastic waste.
The consumed plastic waste becomes a threat to these individuals. The microplastic consumed by the fishes, crabs can disrupt the food chain as it can cause biomagnification.
The plastic products production and transport to various parts of the world also cause harm as these activities involve the use of fossil fuels which leads to an increase in the concentration of carbon dioxide.

what will happen when tendons is removed
Answer:
Tendon release, also known as tenotomy, is a surgical procedure that involves cutting through or disconnecting a tendon to allow for a greater range of movement.
The procedure is used to relieve tight or shortened muscles. In some cases, the tendon is re-routed to maintain muscle function.
This procedure is usually reserved for conditions that don’t respond well to conservative nonsurgical treatments. Tendon release surgery is ideal for infants with clubfoot, or for older patients who develop tightened or shortened muscles due to cerebral palsy or other neuromuscular disorders.

Diffusion across a semi permeable membrane
Paragraph plz
Answer:
This is the movement of molecules and ions from one medium to another,based on the concentration gradients, diffusion distant and area exposed. The plasma membrane is made up of phospholipid-bi-layer, to regulate what passes through.
However,because most of the molecules that diffuses across the membrane are small,non-polar, the bi -layer can not restrain their movements. O2, CO2 and lipids cross this barrier with ease by simple diffusion. However, polar molecules are restricted from passing through..
