An atom will usually form either an ionic bond or covalent bond with another atom but not both.
Ionic bonds are the kind of bonds that result when one atom transfers or gives up electrons and another atom receives them and adds them to its own energy shells.
An example is sodium metal and chlorine gas. Sodium gives up two of its electrons and Chlorine receives them and the two elements form an ionic bond to create sodium chloride, a new compound.
Covalent bonds are the kind of bonds formed when two atoms decide to share electrons. No atom gives up any electrons and neither does the other atom receive any. An example is water. An oxygen atom shares two of its electrons with two hydrogen atoms to form a molecule of water (H2O).
The nucleus of an atom contains the protons and the neutrons.
Answer:
Epiphyseal plate
Explanation:
The growth plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place.
Explanation:
<u>C. A red allele is present on both homologous chromosomes</u>
<u></u>
Homologous chromosomes are pairs of chromosome of similar lengths, banding patterns, and centromere positions, with genes at the same loci. For dominance, gene copies are present on both of the chromosomes; the dominat variant overrides the effect of the other recessive allele.
Further Explanation:
DNA molecules contain chromosomes that may have different forms called alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new alleles, impacting the associated mRNA, and thus the encoded protein.
Homozygous individuals have a chromosome containing two variants of the same allele. Dominant homozygous individuals bear two copies of the dominant allele, whereas recessive homozygous individuals hold two copies of the recessive allele.
