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

Biology

Ivenika [448]3 years ago
6 0

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.

Hoe do compounds differ from elements
pogonyaev
Compounds are made up of elements.

Elements are the ones we pull straight out from the periodic table.

For example:
H2O, HCl, NaCl, NaOH --> these are all compounds

H, N, B, Ne, Na, Cl, O, K --> these are all elements.

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern
Keith_Richards [23]

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.

<h3>What are homeotic genes?</h3>
  • Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
  • These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
  • Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
  • Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
  • The loss of function of any of the gene changes the body pattern and affects the development.

10. A mutation in which types of cells would only affect the organism and not future generations?
Alborosie

Answer:

Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.
