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.

) Name the 3 polymers of carbohydrates and describe the structure and function of each of them.
Answer:
The correct answer is - starch, glycogen, and cellulose.
Explanation:
Polysaccharides are the name of the polymers of carbohydrates that have long chains of monosaccharides connected together. Carbohydrates like starch, glycogen, cellulose, are long polymers of monosaccharides.
Starch produced by plants and is a long-term storage form of sugar. Starch is also the major source of food and is made of two major polysaccharides amylose, linear polysaccharide of α-1,4-linked d-glucopyranose with a few branches of α-1,6 linkages, amylopectin, amylopectin possesses a branched structure with α1–4 as well as α1–6 glycosidic linkages.
Glycogen is a polymer of glucose residue with α-1,4 glycosidic bonds and after every 10 residues, there is branches off via α-1,6 glycosidic linkages. It is the second storage form of energy.
Cellulose is the structural polymer that is made up of unbranched chains of glucose molecules linked via beta 1-4 glycosidic bonds every second glucose is inverted in this polysaccharide.

how can we differentiate between strong and weak acids using indicator?
Answer:
simple...
Explanation:
If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid
What happened to make the K-T boundary?
Answer:

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.

The definitions in the attachment is numbered accordingly as follows:
1. Electrophoresis
2. Polymerase Chain reaction
3. DNA probe
4. Chromosome
5. Restriction enzyme
Explanation:
1. Gel electrophoresis is a biological technique used to separate DNA fragments according to their size and charge using electric current passed through a gel matrix containing the samples.
2. Polymerase chain reaction, commonly known as PCR, is a molecular technique developed by Kary Mullis. It is used to make million copies i.e. amplify of a specific segment of DNA from a very small amount of DNA.

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

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.

Scientists have determined that Earth's interior has layers with different properties. One property is that the inner core is solid. Which of the following statements can be used as evidence to support this property?
Answer:
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius.[1][2]

The internal structure of Earth
There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle. Information about Earth's core mostly comes from analysis of seismic waves and Earth's magnetic field.[3] The inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at the inner core's surface is estimated to be approximately 5,700 K (5,430 °C; 9,800 °F), which is about the temperature at the surface of the Sun.[4]
