Why do you think carbohydrates are used as a source if quick energy rather than fat?

1 answer:

3 0

1) carbohydrates cannot be dissolved easily unlike fats as they are insoluble in water.therefore the amount of energy given from carbohydrates lasts longer than fats 2)fats can be accumulated on the coronary artery(the artery which supplies blood to the heart)there lots of intake of fats can result in heart attack 3)carbohydrates are non sticky and from chain of compounds unlike fats.

Describe how energy flows in the ecosystem represented by this food pyramid how would you translate the pyramid into words?

Ilia_Sergeevich [38]

Energy flows from one animal or plant eating or getting eaten to the next anima above it. As for your translation, the crickets are eating the grass then are getting eaten by the secondary consumers and finally getting fed to the largest consumer and every time you go up in the food chain more and more energy is being passed on.

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s

inn [45]

Answer: 1. S = 0.77

2. R = 0.14

Explanation:

1. Selection differential is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. Response to Selection is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. Heritability is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

$h^{2}=\frac{R}{S}$

$h^{2}=\frac{0.14}{0.77}$

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.

What are some characteristics that green algae and kelp share?

tiny-mole [99]

Answer:

Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch.

In water, red light is fully absorbed at about 15 m, orange light is fully absorbed at about 30 m, yellow light is fully absorbe

zhuklara [117]

Answer:

The photosynthetic organisms of the water can survive at a depth of 100 meters due to the presence of blue light.

Explanation:

There are two colors which are responsible for the process of photosynthesis. These two colors are red and blue. Red and blue light of solar radiation is absorbed and green light is reflected back by the green pigment called chlorophyll. So in the depth of 100 meters in the water, blue light is present so plants can make their own food during photosynthesis.
