2. BB = Blue (because there are two dominant alleles) Bb = Blue (because there is a dominant allele) bb = green (because there are two recessive alleles)

3. Tall eyeballs = TT, Tt. Short eyeballs = tt

4. A. Heterozygous round eyes = Rr, RR. Oval eyes = rr

B. (attached Punnett Square)

C. Rr, rr

D. Round Eyes = 50%

E. Oval Eyes = 50%

5. A. Patrick = TT, Patti = tt, Children = Tt

B.(2nd attached Punnett Square)

C. TT would be tall because there are two dominant alleles allowing the tall gene to be shown. tt would be short because there are two recessive alleles allowing the short gene to be shown. Tt would be tall because the dominant (tall) allele would be shown.

I just have a question, are you in seventh grade? I keep my binders from past years and I remember learning this, but don’t know if that’s the grade I learned it in, are you?

True or False: If one thing in a food web is affected, it will only probably affect the organism that directly relies on it for

joja [24]

Answer:

False

Explanation:

Due to the fact that all the organisms are connected in a chain, the energy flow would be affected and that would result in many organisms being deprived of energy they need and that creates a chain effect.

_______________ refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesio

dybincka [34]

Answer:

Liquefaction refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesion and mechanically fail to provide support during earthquake shaking.

Explanation:

Liquefaction occurs when an unbound material (usually sand), which is saturated in water, loses its resistance to shear due to intense and rapid vibration (earthquake), which breaks its granular structure by reducing its inter-granular pressure and flow like a liquid because of an increase in pressure.

Liquefaction usually manifests itself in loose, saturated and non-cohesive soils, formed by young deposits of sands and sediments of similar particle sizes. If the soil is dense there will be less chances of liquefaction. Older deposits, in general, are more dense and cohesive. At higher density, more interstitial pressure is needed for liquefaction to occur.

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answe

Ratling [72]

Answer:

The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.

Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.

BMR calculation = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)

In Harris Benedict Equation, BMR is multiplied by activity factor to determine calories need.

The activity factors in Harris Benedict Equation are:

for no exercise = 1.2

exercise for 1 to 3 days/week or light exercise = 1.375

exercise for 3-5 days/week or moderate exercise = 1.55

exercise for 6-7 days a week or hard exercise = 1.725

exercise for 2 times training = 1.9

So, calculation for my calorie needs is as following:

BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945

Calorie needs = BMR x 1.55

= 974.945 x 1.55

= 1511.16 calories

What’s the difference between starch and glycogen

MakcuM [25]

Starch is stored in plants and is present in Amylose and Amylopectin while glycogen is found in animals and is stored in the liver. Glycogen is an extensively branched chain of glucose molecule.
