What three (3) factors determine the reactivity of elements? Explain and give examples of each.

Ivenika [448]

Three factors that determine the reactivity of elements are the valence electrons are the electrons in the outermost electron shell of an atom. The number of electrons in an atom's outermost valence shell governs its bonding behaviour. That is why in periodic table the elements were put together according to their numbers of valence electrons.

METALS

The most reactive kind of metallic element is a metal from Group 1 sodium or potassium.

An atom in Group 1 has only one valence electron.

NON-METALS

A nonmetal tends to attract another valence electrons to attain a full valence shell.

In what way does crossing over influence the genetic variation of offspring?

gogolik [260]

Answer:

A and B are both correct.

Explanation:

Chromosomes from both parents are interchanged, which increases the number of possible combinations that the offspring can receive.

Which statements correctly describe the inheritance pattern for the alleles that control blood type? Check all that apply. IA is

Korolek [52]

Explanation:

both IA and IB are dominant- A and B groups show co-dominance

Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For co-dominance, both of a gene's alleles are present, and notable in the phenotype.

Blood glycoprotein alleles are crucial to blood type determination for the ABO system in humans- i does not lead to modifications, while IA leads to the modification of adding N-acetylgalactosamine to the H-antigen on red blood cells; and IB adds galactose

$I_{A} I_{B}$ = blood type AB while $I_{A} I_{A}$ = blood type A while $I_{B} I_{B}$ = blood type B. Since $I_{A} I_{B}$ are both dominant over ii, those with that allele have blood type O.

The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.
