Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."
------------------------
After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.
Mendel named dominant the expressed variant.
Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.
He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.
Mendel named recessive the second alternative variant.
Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.
These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.
He thought that alleles separate -segregate- during the process of gamete formation.
The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

how do you propagate trees
Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.

The different forms matter can take are referred to as states or countries.
Answer:
Three States of Matter
Learning Objective
Describe the three states of matter
Key Points
Matter can exist in one of three main states: solid, liquid, or gas
The states of matterThis diagram shows the nomenclature for the different phase transitions.
Solids
A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.
In crystalline solids, particles are packed in a regularly ordered, repeating pattern. There are many different crystal structures, and the same substance can have more than one structure. For example, iron has a body-centered cubic structure at temperatures below 912 °C and a face-centered cubic structure between 912 and 1394 °C. Ice has fifteen known crystal structures, each of which exists at a different temperature and pressure.
A solid can transform into a liquid through melting, and a liquid can transform into a solid through freezing. A solid can also change directly into a gas through a process called sublimation.
Liquids
A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid because the pressure is higher than the triple point of the substance. Intermolecular (or interatomic or interionic) forces are still important, but the molecules have enough energy to move around, which makes the structure mobile. This means that a liquid is not definite in shape but rather conforms to the shape of its container. Its volume is usually greater than that of its corresponding solid (water is a well-known exception to this rule). The highest temperature at which a particular liquid can exist is called its critical temperature.
A liquid can be converted to a gas through heating at constant pressure to the substance’s boiling point or through reduction of pressure at constant temperature. This process of a liquid changing to a gas is called evaporation.
Gases
Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container. Gas molecules have enough kinetic energy that the effect of intermolecular forces is small (or zero, for an ideal gas), and they are spaced very far apart from each other; the typical distance between neighboring molecules is much greater than the size of the molecules themselves.
A gas at a temperature below its critical temperature can also be called a vapor. A vapor can be liquefied through compression without cooling. It can also exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid).
A supercritical fluid (SCF) is a gas whose temperature and pressure are greater than the critical temperature and critical pressure. In this state, the distinction between liquid and gas disappears. A supercritical fluid has the physical properties of a gas, but its high density lends it the properties of a solvent in some cases. This can be useful in several applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacturing of decaffeinated coffee.
Phase Changes –What does a phase change look like at the molecular level? This video takes a look at the molecular structure of solids, liquids, and gases and examines how the kinetic energy of the particles changes. The video also discusses melting, vaporization, condensation, and freezing.

Crabs, pilchards, blennies and snappers are the examples of secondary consumers.
Crabs, pilchards, blennies and snappers are considered as secondary consumers because they feed on primary consumer which feed on producers such as plants and algae. Secondary consumer are those organisms which feed on herbivorous organisms or primary consumers.
They can feed on producers due to different digestive system so we can conclude that crabs, pilchards, blennies and snappers are the examples of secondary consumers.

Which of the following statements about the law of independent assortment is correct?
A. It is the reason that dominant alleles are visible in the organism's phenotype.
B. It is the consequence of having two copies of each chromosome in somatic cells and one copy in gametes.
C. It describes the inheritance of different genes relative to one another.
D. It describes the inheritance of different alleles relative to one another.
The statement about the law of independent assortment which is correct is: C. It describes the inheritance of different genes relative to one another.
Independent assortment can be defined as a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
This ultimately implies that, the inheritance pattern of different genes with respect to another gene is given by the law of independent assortment.
In conclusion, the law of independent assortment describes how different genes separate with respect to another gene during the development of reproductive cells.
