What happened to make the K-T boundary?
Answer:
A meteorite big enough to be called a small asteroid hit Earth precisely at the time of the K-T extinction. The evidence for the impact was first discovered by Walter Alvarez and colleagues. They found that rocks laid down precisely at the K-T boundary contain extraordinary amounts of the metal iridium

If two organisms have similar traits of DNA they probably
Answer:
4th Option, share a common ancestor.
Explanation:
If two organisms have similar traits of DNA they probably share a common ancestor is the most suitable option to fill the blank.
When the two organisms have similar traits of DNA they probably share a common ancestor.
Two organism have the same traits:When the genes are shared so it preserved the ancestor record where they share with each other and excludes the bacteria.
And, if the DNA is the same for two organism so they would share the a common ancestor.
hence, the last option is correct.

Which of the following is true about the coasts of North and South America? O A. Little industry is located along the coasts, B. There are few cities and the population is sparse. O c. A majority of the population is located there. D. People go to the coasts only when on vacation,
Answer:
The correct answer is C. In North and South America, a majority of the population is located on the coasts.
Explanation:
Historically, the vast majority of civilizations have sought to establish their urban centers around bodies of water, be they rivers or seas, that allow them a rapid expansion outward as well as channels through which to channel trade. Thus, it can be seen how throughout the world and especially the American continent, large cities and population centers are located primarily on the coasts. Examples of this situation are Vancouver in Canada, New York and Los Angeles in the United States, Rio de Janeiro in Brazil or Buenos Aires in Argentina.
why might patients who go into remission get a different type of cancer?
Answer:
Remission can be partial or complete. In a complete remission, all signs and symptoms of cancer have disappeared. If you remain in complete remission for 5 years or more, some doctors may say that you are cured. Still, some cancer cells can remain in your body for many years after treatment.

Answer:
Hard water can cause your dark clothes to fade faster than they should. ... Explanation:
You get those stains for the same reason you get similar-looking stains inside porcelain sinks and toilets – iron in the water. Household water containing a lot of iron may leave those stains on your clothes.
crabtree effect on glycolysis
Answer: 'At high fructose concentrations, respiration is inhibited while glycolytic end products accumulate, a phenomenon known as the Crabtree effect. It is commonly believed that this effect is restricted to microbial and tumour cells with uniquely high glycolytic capacities (Sussman et al, 1980).

For a typical human aorta, the diameter of the lumen is 30 mm and the thickness of the wall is 4 mm. Assuming a blood density of 1.06 gm/cc and a viscosity of 0.035 Poise, calculate the Womersley number if the heart rate is 70 bpm. Diameters for the carotid and femoral arteries of a typical human are about 0.8 cm and 0.5 cm, respectively. Compute the Womersley numbers for each of the arterial segments for the same heart rate and explain if the flows can be assumed steady or not.
Answer:
Womersley numbers : 22.25 , 5.96 , 3.72
Explanation:
Calculate the Womersley number if the heart rate = 70 bpm
For the Human Aorta
∝ = r [tex]\sqrt{\frac{wp}{u} }[/tex] ------ ( 1 )
r = radius = 15 mm = 0.015 m
w = 2πf = 2 * π * 70 = 439.82
p = density of blood = 1060 kg/m^3
u = 0.035 P = 3.5 cp = 3.5 * 10^-3 Ns/m^2
Back to equation ( 1 )
∝ = 0.015 * [tex]\sqrt{\frac{439.82*1060}{60*3.5*10^{-3} } }[/tex] = ( 0.015 * √466209.2 / 0.21 ) = 22.35
For Carotid artery
r = 0.8 cm / 2 = 0.4 cm = 0.004 m
w = 2πf = 439.82
Womersley number = ( 0.004 * √466209.2 / 0.21 )
= 0.004 * 1489.981 = 5.96
For Femoral artery
r = 0.5 cm / 2 = 0.25 cm = 0.0025 m
Womersley number = 0.0025 * √466209.2 / 0.21 )
= 0.0025 * 1489.981 = 3.72
The flow is unsteady because of the varying Womersley numbers

A 4-base deletion in the AAUAAA sequence in the 3' untranslated region of an mRNA that eliminates the AAU, thereby preventing RNA Polymerase from polyadenylating the mRNA, would have the effect of:
Answer:
decreasing the number of copies of the polypeptide translated from this mRNA
Explanation:
Polyadenylation refers to the addition of multiple adenosine monophosphates (i.e., a polyA tail) to an RNA molecule, usually a messenger RNA (mRNA). Polyadenylation is catalyzed by an RNA polymerase called poly(A) polymerase (PAP), which adds adenine nucleotides to the mRNA. In eukaryotic cells, polyadenylation is required to produce a mature mRNA which is then used as template for protein synthesis during translation. This posttranscriptional modification (polyadenylation) is known to stabilize the mRNA by preventing its degradation by exoribonucleases, i.e., enzymes that degrade RNA molecules by removing terminal nucleotides from 3' and 5' ends. In consequence, it is expected that a mutation that prevents polyadenylation of a target mRNA decrease the number of copies of the protein translated from this mRNA.

Why can't weeds take over the world? In other words, what limits the growth of populations?
Answer and Explanation:
Many elements can limit population growth. The main elements that can cause this are the lack of resources necessary for the life and development of living beings and the lack of space to be taken by them. In relation to weeds, these resources can be the availability of sun, amount of soil, soil fertility, availability of water and space. However, these plants are very resistant to the lack of these resources, and what most limits their growth is human interference.
Weeds are unfavorable to agriculture and other human activities. This makes humans fight the population growth of these plants using chemical products and even physical strategies. This interference prevents weeds from taking over the world.

Which event might disrupt a stable ecosystem?
A
Green plants use chlorophyll to produce food.
B
An invasive species enters the environment.
Consumers eat producers.
D
Predators kill prey.
Answer:
An invasive species enters the environment.
Explanation:
All other answers already naturally happen in an environment so they are stable. But if an invasive species enters, the ecosystem will be less stable because invasive species dominate ecosystems which isn't natural to the animals that live there. So for example, if someone introduced an invasive species to the ecosystem, it can cause many changes like if it was a predator, there'll be less primary consumers (the animals that eat plants) because the invasive species isn't natural to them.
Answer:
B
Explanation:
An invasive species enters the environment is the correct answer.
