Answer:

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes comes in pairs and are inherited as distincts units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominate or recessive traits.

How can a punnett square predict the traits of offsprings
Anna35 [415]

A punnet square predict the traits of offspring genetic crosses and test crosses.

<u>Explanation:</u>

In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.

The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by  genetic crosses. In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.

torisob [31]

Answer:

16) 6 electrons

17) 6 protons

18) 6 neutrons

19) 4 electrons

20) 6

Explanation:

There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.

sergey [27]

The presence of a controlled substance must be proven in both the blood and the organs before it can be considered as a cause of death.

Blood is a red colored fluid present inside the body. It is red due to the presence of a pigment called hemoglobin. The blood is responsible for the transport of substances across the whole body, like oxygen, hormones, carbon dioxide, waste material, etc.
