natulia [17]

Answer:

A punnet square can be described as a diagram which is made to check the outcomes of a cross.

To check the probability of the offsprings of a cross between homozygous dominant thumb shape parent with a homozygous recessive thumb shape parent, let's draw a punnet square:  

        t              t

T    Tt            Tt

T    Tt            Tt

The results of the punnet square depict that:

Genotype: All of the offsprings will be heterozygous for the thumb shape trait. Tt will be the genotype.

Phenotype: All of the offsprings will show the thumb shape like the thumb shape of the dominant parent.

Imagine that part of a population of South American finches is blown by a storm onto an island far offshore and manages to survi
lina2011 [118]

Answer: The observation "A" leads us to conclude that the finches populations are from two different species

Explanation:

According to the biological concept of species, <em>a set of individuals are from the same species if they are able to reproduce and leave fertile offspring</em>. This is key so one species can be successful and perpetuate through time. If they cannot leave descendants, then the species will be extinct. However, it’s possible that two individuals from different species mate and have descendants, but they cannot leave fertile offspring. When they are from different species, the offspring will be sterile and it is called a hybrid.  

In the case of the South American finch, the island's finch population and mainland's finch population belong to different species because their offspring is sterile. To have different features, as different feather's color, or to have other dietary preference is not enough to say that they are different species. This is because within the same species, individuals can have variations. For example, we can different eye color and belong to the same species.

Compare the physical and chemical properties of a compound to those of the elements of which it is composed
zepelin [54]

Answer:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water H_2O

2H_2O(l)\rightarrow 2H_2(g+O_2(g)

Physical property is defined as the property of a substance which becomes evident during physical changes. Water is liquid at room temperature whereas hydrogen and oxygen are gases at room temperature.

Chemical property is defined as the property of a substance which becomes evident during chemical changes. Water reacts with metals to form bases, hydrogen reacts with metals to form hydrides and oxygen reacts with metals to form oxides.
