Answer: Cross breeding

Explanation: Cross breeding can be defined as the method by which two plants can be crossed to produce the desired character and compensate the useless characters shown by the plants individually.

Suppose a plant produces pink flower but small slower and another plant produces white flower but big flower.

If we want big pink colored flower then, these two plants can be crossed among each other so to produce the desired characters and hide the useful characters.

PLZ HELP!
Setler [38]

Answer:

The answer is RNA

Explanation:

Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.

Do you notice a pattern in the charge for elements in each group? Explain.
MrRissso [65]

Answer:

Below are some patterns in the charge for elements in each group.

Group 1 elements : 1 valence electron and form ions with charge +1

Group 2 elements : 2 valence electrons and form ions with charge + 2

Group 3 elements : 3 valence electrons and form ions with charge + 3(there are some exceptions as well)

Elements in groups 4 and 5 are unpredictable also the D block elements consist of multiple oxidation states..

Group 6 elements : 6 valence electrons, form ions with charge -2

Group 7 elements: 7 valence electrons, form ions with charge -1  

The octet rule is being followed, the elements form either ionic bond or covalent bond to fulfill it.

eg: when a K atom forms a K+ ion, the ion has the same electron configuration as the noble gas Ar (argon).

When an O atom gains 2 electrons to form the O²⁻ ion, the ion has the same electron configuration as the noble gas Ne (neon).  

Note: Boron (B) is in Group 3 but doesn't form ions.

Place the following compounds in order of increasing strength of intermolecular forces. HF H2 CH3Cl
Scorpion4ik [409]

Answer:

H2 < CH3Cl < HF

Explanation:

The intermolecular forces are the forces that bond the molecules together in a substance. There are three types of these forces:

  1. Dipole induced -dipole induced, or London dispersion -> Is the weakest and is presented in nonpolar molecules, in which a dipole is induced and so the molecules are joined together;
  2. Dipole-dipole -> Is stronger than the London dispersion and occurs in a polar molecule. In this case, the dipole already exists (partial positive and negative charges), so the poles are attracted;
  3. Hydrogen bond -> It's the strongest and is formed when the hydrogen is bonded with a higher electronegativity element (F, O, and N).

So, the molecule of H2 is linear and formed by the same element, so, is nonpolar, and has London dispersion forces. The molecule of CH3Cl has 3 nonpolar bonds (C-H), and one polar bond (C-Cl), so it's polar and has dipole-dipole forces. And the HF molecule has hydrogen bonds.

*A polar bond is a bond formed by elements with different electronegativities.
