Answer:
1) Autotrophs transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) eat producers, make use of some of the energy, making from it their biomass.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy.
4) Decomposers (last order in the chain) recycle all the dead organic material and make use of some of the stored energy.
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.
From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.
Organisms that can use light, and turn it into organic matter according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, algae, and bacteria that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic web, heterotrophic organisms occupy the first, second, or third consumer level, after producers. There are different types of heterotrophic animals: carnivorous, herbivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
The progressive reduction of energy determines the number of trophic levels in the chain (4 or 5).
1) Autotrophs use water, CO2, and solar energy to produce O2 and glucose, by the process of photosynthesis and convert it into biomass. Producers transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) make use of some of this energy to survive, making from it their biomass. The rest of the energy is lost.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy. The rest of the energy is lost.
4) When different organisms die, decomposers (last order in the chain) recycle all the organic material and make use of some of the energy stored in their tissues. The rest is lost.

Describe the Cell Cycle [Interphase, G1 phase, S phase, G2 phase]
Explanation:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 pahse (cellgrowth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis.
Identify and describe the three ways the mutations affect organisms
Answer:
they may cause the development of a disease-causing allele
they may cause the development of a more beneficial allele
they, in some cases, may have no noticeable affect.
Explanation:
Answer:
Mutations may be beneficial, harmful, or neutral to organisms. If the change caused by a mutation is useful to the organism, then it is beneficial. If the change is damaging to an organism, then it is harmful. If the change is neither useful nor damaging, then the mutation is neutral.

investigate the conditions required for seed to germinate. keep the dishes at room temperature for a week.explain your observations
Dry cotton wool
wet cotton wool
covered with water
Explanation:
Starting off, the conditions required for a seed to germinate are:
warm temperatures, so that enzymes can act efficiently.water, for chemical reactions to place.oxygen, for respiration.Observations:
Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)
Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.
Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.

Jill is blood Type O. She has two older brothers (who tease her like crazy) with blood types A & B. What are the genotypes of her parents with respect to this trait?
Answer:
There you have it. Jill's parents are IAi & IB
Explanation:
one brother: Type B, one of the parents must have the IB allele
other brother: Type A,
other parent must have the IA allele & have a genotype of IAi.
Jill's parents are IAi & IB
Jill's parents have the genotypes IAi and IBi.
What is blood type?Blood type refers to the classification of blood based on the presence or absence of certain antigens on the surface of red blood cells. The most common system used for classifying blood types is the ABO system, which has four types: A, B, AB, and O.
If Jill's blood type is O, then she inherited an O allele from each of her parents. Since her two older brothers have blood types A and B, we can conclude that her parents are both heterozygous for the A and B alleles (IAi and IBi). This means that each parent contributed an i allele to Jill, resulting in her blood type O.

how do they treat patients with diabetes? where does the insulin come from? and how do people get insulin? help me please
People with diabetes need to take insulin to help process the sugar, or they can't use it and it stays in their blood. The insulin allows sugar into the cell to be used, which is why diabetics need to take insulin. Insulin is usually prescribed by a medical professional.

Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.

If i added 27 grams of salt to water and saparated the solution with a hot plate what amount of salt will be left behind
Answer:
27 grams
Explanation:
27 grams of salt would still be left behind.
The dissolution of salt in water is a physical reaction and the salt can be recovered by evaporating off the water using appropriate procedures.
Provided that no part of the salt/water mixture is lost during the process of evaporation, if 27 grams of salt was dissolved initially, the same amount of salt would be recovered at the end of the separation process.
