Explain what the greenhouse effect is, use diagrams if you wish.
Include:
-Radiation from the sun absorbs earths heat
-Some emitted
-Trapped by the greenhouse
Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

X-rays carry a small risk of damaging DNA which can lead to cancer. Why are they still used by doctors?
Answer:
Despite the risk of DNA damage and cancer production, X-rays are still used by doctors because the benefit of this diagnostic study outweighs the risk, which in most cases is very low.
Explanation:
Diagnostic radiology studies, such as X-rays and CT scans, are procedures that use ionizing radiation to obtain images of the inside of the body. Prolonged or constant exposure to this type of radiation is harmful because there is a risk of producing damage to DNA and can lead to the development of cancer.
However, the use of X-rays and CT scans are non-invasive diagnostic methods whose information provides an accurate diagnosis of a disease and, when well used, has a very low risk of organ damage.
Ionizing radiation is measured in milisieverts (mSv) and exposure from radiologic studies is in the range of 0.1 to 10 mSv per study. The amount of ionizing radiation a person is expected to receive per year from exposure to their environment is in the order of 3 to 5 mSv per year, so diagnostic imaging studies involve a low risk of organ damage.
Doctors continue to use X-rays as a diagnostic study, despite the risk of cancer and DNA damage, because the benefit —accessible, noninvasive, and cost-effective— far outweighs the risk.
What are some benefits to evolutionary adaptations?
Answer:
1.A new species
2.Adding to world population
3.More to learn
Explanation:
whats this,in order?
Answer:
1. Individuals in a species vary in characteristics because of differences in their genes.
Individuals will be born with various characteristics due to their genes for instance some people are short and other are tall.
2. Individuals have to compete when resources (such as food) are limited.
Resources are generally limited so individuals would have to compete t get those resources and survive.
3. Individuals with variations that help them get more of the resources are more likely to survive.
Some of the characteristics that these individuals have which are different will give them an edge and enable them to get more resources and thus survive.
4. Individuals that survive can pass their genetic variations on to their offspring.
The individuals that survive will now have offspring and will pass on their genes to their offspring which give give them the same edge their parents had.
5. Over time, there are more individuals with the variations that are well adapted to the environment.
Eventually there will be more of those offspring that can adapt as opposed to those who couldn't and keep dying out.
Describe what happens to water particles when ice metls.
Answer:Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water. In the melting process, the water molecules actually absorb energy.

explain how science uses fossil evidence to support the theory of evolution
Answer:
they compare fossils to other fossils to see if skeleton changes are observed in a species over time it indicates that there is genetic change going on within the species
Answer:
Science uses fossil evidence to support evolution theories because you can link similar fossils among creatures from millions of years ago, to the living creatures of today.

Which of the following are ways that the respiratory system works with the immune
system to keep humans from getting sick? (Choose all that apply
1.) Coughing involves a quick contraction of the diaphragm muscle, forcing air
through the respiratory pathway, and dislodging mucus or other harmful
particles
2.) Alveoli transfer bacteria and viruses to the bloodstream to be disposed of.
3.) Cilia function like a filter, trapping dust and pollen in the nose,
4.) Mucus traps bacteria and viruses to be removed or swallowed.
Answer:
1.) Coughing involves a quick contraction of the diaphragm muscle, forcing air
through the respiratory pathway, and dislodging mucus or other harmful

3.) Cilia function like a filter, trapping dust and pollen in the nose,
4.) Mucus traps bacteria and viruses to be removed or swallowed.
Explanation:
Coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.
What is Respiratory system?The respiratory system is defined as the network of organs and tissues that help us breathe which includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system where these parts work together to move oxygen throughout the body and clear out waste gases like carbon dioxide.
Respiratory system works in that way with the immune system by keeping the human from getting sick by bacteria and viruses are removed or swallowed by mucus, while the cilia act like a filter, trapping dust and pollen in the nose.
Thus, coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.

1. How does your DNA differ from other peoples?how is it similar
2.How does your DNA differ from a strawberries DNA? How is it similar
Answer:
1.DNA is more than 99% similar between any two people. All the differences in how we look, feel, behave and the differences in our health are due to less than 1% difference
2.In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA that means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see.

Explain enzyme-substrate specificity.
[tex]\purple{\tt{\huge{Answer}}}[/tex]
substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product
