What is the relationship between coronary artery disease and a heart attack?
A. Coronary artery disease is a symptom of heart attacks.
B. Heart attacks reduce blood flow to the heart and cause coronary artery disease.
C. Coronary artery disease can reduce blood flow to the heart and cause heart attacks.
D. Heart attacks occur when coronary artery disease is treated.
C) Coronary artery disease can reduce blood flow to the heart and cause heart attacks
CAD (or atherosclerosis) affects the vessels that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower. And due to inadequate supply of blood, the heart muscles get damaged. This can lead to a heart attack!
Mutations in which of the following cells would get passed on to the next generation?
I. sperm
II. Skin cell
III. Egg
IV. Neuron
A. II, III, and IV
B. III only
C.I and III
D. I, III, and IV
Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III

5. Shawn has a hypothesis that fungicides harm bee development. Using what you now know, describe an experiment to test Shawn’s hypothesis. Be sure your response includes what data should be collected and how you would collect it.
Answer:
Yes.
Explanation:
Yes, the fungicides harm bee development by causing changes in behavior, immune health, and reproduction etc. For verifying this hypothesis, we have to take two environments, in one environment fungicides are applied to the plants while on the other environment, there is no fungicide applied to the plants. Th result shows that the bees are affected and act abnormal where fungicides are applied as compared to those bees which are normal in behaviour and other features.

In Gregor Mendel's work with pea plants, he found that when a tall pea plant, with genes TT, was crossed with a short pea plant, with genes tt, that _____ % of the first generation of offspring plants were _____.
Answer:
In Gregor Mendel's work with pea plants, he found that when a tall pea plant, with genes TT, was crossed with a short pea plant, with genes tt, that _100_ % of the first generation of offspring plants were tall pea plant_.
Explanation:
After crossing the two types of plants, Mendel observed that among the F1 there were only tall variants, while the other variant (short) disappeared. Mendel named "dominant" the expressed variant. Mendel then let these new plants auto pollinate and observed the results in the second generation, F2. He saw that the short variant that had previously disappeared, reappeared again. Both tall and short plants were present in the F2. Mendel named "recessive" the second alternative variant.
Mendel explained his results by arguing that discrete factors were responsible for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each plant had a pair of factors -which he named alleles-, and that each factor coded for one trait -tall and short-. He thought that these factors -T and t- separate -segregate- during gamete formation. This conclusion is known as the segregation principle (First Mendels´ Low).
Apply logarithm to evaluate T given 644 204=400 000 (1+10%)^T,by first simplify the equation.
The value of T after applying logarithm to evaluate the function is 4.9988
Given the expression
[tex]644 204=400 000 (1+10 \%)^T[/tex]
Since 10% = 0.1, the expression becomes;
[tex]644 204=400 000 (1+0.1)^T\\644 204=400 000 (1.1)^T\\\frac{644204}{400000} =1.1^T\\1.61051=1.1^T[/tex]
Take the logarithm of both sides
[tex]log1.61051=log1.1^T\\log1.61051=Tlog1.1\\Swap\\Tlog1.1=log1.61051\\T=\frac{log1.61051}{log1.1}\\T=\frac{0.2069}{0.04139} \\T=4.9988[/tex]

If the time interval is 55 seconds, what is the distance to the epicenter?
what is 2 plus two and what is four plus four and what is five plus five and what is six plus six
Answer:
2+2=4. 4+4=8. 5+5=10. 6+6=12.
Explanation:
I'll just explain one? It takes around 360 pages to fully prove 1+1=2 so I'll just explain it the way I do. Draw some tallies. Draw 2 tallies and 2 more next to them. Count the total tallies, and you should get 4. (Sorry about this)

What is photosynthesis????
Explanation:
The process of green plants make their own food by present sunlight is called photo synthesis
I don't need follow or thanks but please subscribe to my mom channel
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.
Hope this helps!
Have a great day! :)

Explanation:Substrate-level phosphorylation is a type of metabolic reaction that results in the formation of Adenosine Triphosphate (ATP) of Guanosine Triphosphat (GTP) by the direct transfer and donation of a phosphoryl (PO3) group to Adenosine Diphosphate (ADP) of Guanosine Diposphate (GDP) from a phosphorylated reactive intermediate.
In glycolysis substrate level phosphorylation occurs in following two reactions
(i) 2molecules of 3-phosphoglyceric acid react with 2 molecules of ADP to from 2 molecules of 3-phosphoglyceric acid and 2 molecules of ATP.

what happens if we do not eat food ?
Answer:
If we do not eat food we will not get energy.
Answer:
When someone doesn't eat food, the effect might surprise you. That person will not die immediately, they might pass out and starve but you can go a long time with out eating, sometimes maybe a week! But that is what happens when you do not eat food, now if you do not drink water for a long time, you might actually die. Sometimes, you can't even spend a day without drinking water.
So, when you don't eat food you will not die, just starve. But when you don't drink water, you will die.

Assuming that you observed similar patchy bacterial growth pattern in plates "B-Amp, phage" and "C-LB, phage". The T4 phages greatly affected the growth of E. coli strain CR63 in the LB plate ("C-LB, phage" plate), creating a patchy bacterial growth pattern similar to the expected result in the ampicillin plate of strain BE with phage ("B-Amp, phage" plate). Besides experimental errors, describe the possible reasons why the bacterial colonies were isolated in these two plates. "B-Amp, phage" Plate (strain BE)?
Answer:
Some bacterias show a great resistance power to fight against T4 phages That leads to great growth in the medium given that resistance power may be given by plasmids As plasmids show the resistant genes that great work in the medium.
T4 phage is a virus that shows a lytic cycle after affecting bacteria and going to kill the bacterial cells in bacterial strain So no growth in LB media. Some bacteria are sensitive due to the lack of resistant genes therefore, their growth may affect by many factors of the medium. If the bacteria are recombinant, they show greater growth in the medium.
* B-Amp, Phage plate (strain Be), there is ampicillin, so inhibits the growth of bacteria but still there is patchy growth of bacteria and they still show the growth but due to presence of phage T4, they show patchy growth.
