) 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.

What is Groundwater?
Groundwater is the reservoir of water this water accumulates in the ground surface or subsurface of the earth's crust through tiny pores and fractures in the rocks.
The source of water are streams of rivers, oceans, lakes and large depositing is because of water from the rain and melting of the snow. It is a source of freshwater in nature.
Thus, option "B" is correct.

How is mitosis different in plants and animals?
Answer:
The main difference is cell plate formation and how they form the daughter cells during cytokinesis. In plants, they lack centrosomes. A new cell plate will form between the daughter cells for the future cell wall. In animal cells the cell membrane will rather constrict to separates the parent cell into the daughter cells. Plants also do not undergo cell furrowing, unlike animals cells.

Answer:
Normal Eyes = 75%
Heart eyes = 25%
Explanation:
3 of the offspring in that punnet square have at least 1 dominant allele. And if an offspring has at least 1 dominant allele then it should have the dominant trait( which is normal eyes ). But if it only contains recessive alleles then it would have the recessive trait (which in this case would be heart eyes).
What has to be the genotype of an organisms alleles for its recessive traits to appear?
Answer:
2 recessive traits (two lower cased letter if that is what you are referring to)
Explanation:
since the dominate trait can appear if the allele has 1 dominate and 1 recessive, a allele must have 2 recessive genes. (b,b) would work but (B,b) won't work

Green plants are called producers because they take energy from sunlight and produce
food in which the energy is stored. From there the energy goes to organisms that eat the
plants, called consumers. Animals that eat only plants are called herbivores. An easy way to
remember this is to think of herbs like basil, rosemary, and oregano.
Herbivores are in turn often eaten by another kind of consumer called predators, or
carnivores, which means "meat-eaters." These organisms get energy from eating the flesh of
other animals. Animals who eat both plants and meat, like humans, are called omnivores,
which means "everything-eaters.”
Eventually, even predators die. When they do, tiny fungi and bacteria consume the remains
of their bodies. These tiny organisms, called decomposers, get their energy from the flesh
of the dead bodies. Decomposers such as bacteria leave behind only the most basic elements
in the body, like carbon, nitrogen, and phosphorous. These elements are then washed into
the soil by the rain, and the food chain starts all over again.
Which of the following is an example of an omnivore?
Answer:
humans
Explanation:
humans are example of omnivore

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

The igneous activity in Yellowstone National Park is associated with what tectonic setting?
convergent oceanic-continental plate boundary
convergent oceanic-oceanic plate boundary
intraplate setting
divergent plate boundary
Answer:
Inter-plate tectonic setting.
Explanation:
inter-plate tectonic setting is associated with the igneous activity in near proximity to a plate boundary which makes this location of Yellowstone National Park geologically very active, means the numerous gazers, volcanoes, earthquakes, faults occurs in the surrounding area so that's why we can say that the igneous activity in Yellowstone National Park is associated with Inter-plate tectonic setting.

In which biome do herds of caribou and reindeer migrate in and out? A. tropical rainforest B. desert C. Mediterranean/chaparral D. tundra
Answer:
During the summer, they spread across the tundra in smaller groups to feed. In fall, they group together again into larger herds for breeding. They stay in these larger groups throughout their winter migration to the “taiga” regions which are the areas just south of the tundra.
