Why can an animal survive longer without food?

1 answer:

5 0

It depends on the type of animal, but if, for example, you're talking about one lower on the energy pyramid (like a chicken, for example) then this is because of the energy distribution. When an animal consumes something else, it absorbs about 10 percent of the energy of that creature.

So, lets say a plant has 1000 units of energy. Then a bug comes along, and eats the plant, absorbing 100 units (10 percent) of that energy. Then, a chicken eats the bug, absorbing only 10 units of that energy. Finally, a human eats the chicken, getting only 1 unit of the original energy.

The reason that something like a bug has to eat less than a human, is because it gets more energy directly from the plant.

11. A sample of bromine gas has a volume of 236.5 Land

Xelga [282]

According to Charles' law, when the gas is heated to 684 K, the new volume is 338.4 L

Explanation:

Charles' law states that the Volume of an ideal or fixed amount of gas, at constant pressure is directly proportional to Temperature (in kelvin). V∝T

V 1/T 1=V 2/T 2 here, V 1= 236.5 L, T 1= 478 K, T 2= 684 K. Find V 2?

V 2 = V 1 × T 2 ÷ T 1

V 2 = 236.5 L× 684 K ÷ 478 K

V 2 = 338.4 L

Observer each image of the punnet square and list the two phenotypes and the probability of each phenotype occurring.

Marta_Voda [28]

Answer:

In the crossing of two hybrid plants for the color flowers trait can be seen that the phenotypes are purple flowers and white flowers and in the descendants the phenotypes, genotypes and probabilities are purple flowers Bb (50%), purple flowers BB (25%) and white flowers bb (25%).

Explanation:

For the flower color trait, the dominant allele is purple (B) and the recessive allele is white (b). The planted cross shows two purple hybrid flowering plants (Bb) and the offspring can be seen in Punnet square:

Crossing: Bb X Bb

Alleles B b

B BB Bb

b Bb bb

The results in the offspring are:

Plants with purple heterozygous flowers Bb 50%.
Plants with pure purple flowers BB 50%.
Plants with white flowers bb 25%.
