Answer:
E) 2
Explanation:
The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.
Answer:
Endothermic
Explanation:
Amphibians are ectothermic organisms. Ectothermic animals are coldblooded animals. From the options above, the correct answer is endothermic because amphibians are not hot blooded and are never endothermic.
So let’s substitute that into the
third equation and solve for B. B = H + T B = 9 + (9 + 1/2B) B = 18 + 1/2B Then
subtract 1/2B from both sides: 1/2B = 18 Multiply both sides by two: B = 36 Now
we know the value of B and the value of H. Substitute this back into the second
equation and solve for T. T = H + 1/2B T = 9 + (1/2)36 T = 9 + 18 = 27 Step 4:
Plug all values of H, T, and B into the final equation. Total length of fish =
H + T + B Total length of fish = 9 +27 + 36 = 72.
This indicator is an estimate of the amount of space on the earth that an individual uses in order to survive using existing technology. This space includes the biologically productive land and water area that produces the resources consumed by that individual such as food, water, energy, clothing, and building materials. It also includes the amount of land and water required to assimilate the wastes generated by that person. In other words, the ecological footprint measures a person's demand on the bio-capacity of the Earth.
Answer: if i want to breed a rose and i don't have a certain kind of rose, i have to cross between them until i have a kind of rose that express the phenotype i was looking for. Once i've got it, i'll try to cross it with another rose and generate more species like that to cross with the rose that express the phenotype, this favors to generate a specie that have a pure phenotype.
Explanation: The answer is explain by the Mendel's laws.
Mendel's second law:
if you have two roses that are heterozygous and you cross them, their offspring have a 25% probability of generating a homozygous phenotype for a certain recessive characteristic (such as the rich smell of roses that is not a dominant character), 50% of generate heterozygotes with a dominant phenotype, and 25% generate other homozygotes with a dominant phenotype.
Once the offspring with the recessive homozygous character are obtained, it is possible to start making crosses between those of a recessive nature and there Mendel's first law applies
All the homozygous recessive individuals that are crossed will have a 100% homozygous recessive offspring.
Also, if you cross heterozygotes with another heterozygotes the offspring will be 100% heterozygotes
