The most common blood type in the United States is _________. What blood type is safe for a person with this blood type to receive
Answer:
Type O
Explanation:
Type O is the most demanded blood type in hospitals, both because it’s the most common and because O-negative blood is a universal donor type, meaning it is compatible with any blood type. Conversely, type AB-positive blood is called the universal recipient type because a person who has it can receive blood of any type.

Answer:
The answer is If we did an experiment in which the iodine solution was placed in the baggie and the starch solution was in the breaker the iodine would move out the baggie. Once the iodine makes it way out the baggie the starch would change color.

1 Why are Steno's principles important?
2 What clues can scientists use from fossils to determine the age of rock layers?
3 Why is uniformitarianism useful?
4 How do scientists create a geologic history of an area?
5 Fossils give scientists the ability to look back in time. How do they do this?
6 As they study rock layers, what do scientists learn?
7 How are geologic timescales created?
8 The earth has three main kinds of rock. Describe them.
9 How are sedimentary rocks formed?
(I reposted this cuz someone tried to scam meh.
Answer:
1) Steno's principles are important because, he deduced that rocks were laid down in vertical order just as sediments are laid down today, under water.
2) Scientists use a technique called radiocarbon dating to find out the age of the fossils.
3) Uniformitarianism is the principle that we can infer long term trends from those we have observed over a short period. In its stronger sense it claims that processes operating in the present can account, by extrapolation over long periods, for the evolution of the earth and life.
4) The geologic record is the history of Earth as recorded in the rocks that make up its crust. ... The way these strata are arranged and what fossils are in them give scientists clues about what Earth was like billions of years ago.
5) Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.
6) By studying rocks up close, we can learn all sorts of things about Earth's layers, including how old they are (how long ago that layer of the Earth formed), what type of rocks make up each layer (and what the properties of those rock types are), and what minerals form the rocks in each layer
7) The geologic time scale was developed after scientists observed changes in the fossils going from oldest to youngest sedimentary rocks.
8) Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
9) Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension

Answer: Eukaryotic
Explanation:
why do animal cells have more mitochondria than plant cells
Answer:
I believe it's due to the movement and use of energy.
Explanation:
Plants tend to move much less than any animal, even if that animal didn't do very much. Plants don't chase and hunt down prey, but leopards do. Therefore, more mitochondria will benefit the animal who moves, versus the plant that does not.
Mitochondria are energy producers, which plants don't necessarily need more of.

This image from the EPA shows the projected benefits and costs from the most recent amendments to the Clean Air Act. A net improvement in economic welfare is projected because cleaner air leads to better health and productivity for American workers. It also reduces medical expenses for air pollution-related health problems.
alternative pie chart showing comparison of benefits and costs of Clean Air Act Amendment programs
Based on your findings in parts A to C, write a summary paragraph evaluating the Clean Air Act in terms of cost and effectiveness. Cite evidence for your reasoning.
Answer:
One of the health hazards that suprised me is that outdoor pollution is associated with hearth attacks. I know that outdoor pollution causes lung problems whether that's asthma attacks or bronchitis, but I didn't know about heart attacks. Apparently, air pollution can trigger heart attacks, stroke, and irregular heart rhythms. People who are already at risk for these conditions are more likely to have any of those. Air pollution causes damage to the inside walls of your blood vessels, causing them to become narrower and harder. Along with that, there are many different positives and negatives that came from the Clean Air Act some of which are:
Positive Outcome :
Cleaner lungs.
Decreased asthma and allergies symptoms.
Improved skin appearance.
Helps digestion.
Psychological and emotional stabilizer.
Better mood and normalized sleep patterns.
Reduce chances of lung, heart, and arterial diseases.
Negative Outcome :
According to the EPA, when we are exposed to high levels of hazardous air pollutants for an extended period of time .
We face a greater risk of suffering serious health effects, including respiratory diseases, neurological disorders, reduced fertility, damage to our immune system, and increased risks of getting cancer.
I believe that it was effective and there was definitely a purpose to this Act because even though our air pollution is getting worse each day, I'm sure that it isn't as bad as it could be if the Act wasn't put in place.
a greasy and dirty pot results after cooking. this will be cleaned by dishwashing detergent. how does the soap work?
A detergent works by solubulizing grease and forming an emulsion of the grease with water.
A detergent is commonly used as a cleaning agent. Every detergent consists of a hydrophobic tail and a hydrophilic head. The hydrophilic head is capable of interaction with water hence the detergent can dissolve in water. Its hydrophobic tail is capable of interaction with grease.
A detergent works by agglomerating its molecules into micelles which dissolve the grease. Mechanic scrubbing completely eliminates the grease creating an emulsion with water.

The inner medulla of the kidney is ________ to the loop of Henle and therefore, water leaves the loop at the descending limb and collecting duct.
Answer:
The Renal Medulla
Explanation:
The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections.The Loop of Henle (LoH) is a long, straight, tubular segment connecting the proximal tubule to the distal convoluted tubule and lies parallel to the collecting ducts. The LoH descends from the cortex or medulla (depending on the size/length of the nephron) into the papilla of the kidney.

Explanation:
A fellow student asks, "How is
it possible that six feet of DNA
can fit inside a single,microscopic nucleus of a cell?" If you
were to unravel a ball of yarn,
it would probably be able to circle
around your house (that's a
long distance!). Use this
comparison to answer
your fellow student's question.
Answer:
DNA is wrapped around proteins known as histones to form chromatin. Packing the DNA into nucleosomes condenses the DNA approximately sevenfold. It can be further organized by winding the chromatin into more compact structures. Coiling the chromatin around itself decreases the space it occupies by another sixfold or so. Through a series of similar compacting strategies, the entire genome can fit inside the nucleus of a single cell.

do identical twins have the same fingerprints
Answer:
no
Explanation:
Identical twins do not have identical fingerprints, even though their identical genes give them very similar patterns. ... Small differences in the womb environment conspire to give each twin different, but similar, fingerprints. In fact, each finger has a slightly different pattern, even for your own fingers.
Explain why interactions between organisms are important.
Answer:
Species interactions form the basis for many ecosystem properties and processes such as nutrient cycling and food webs. The nature of these interactions can vary depending on the evolutionary context and environmental conditions in which they occur.
