Someone PLEASE help me I don’t remember this.

Answer: genotype: Ee phenotype: two small eyes.

genotype: RR' phenotype: pink eyes

genotype: GB phenotype: green and blue splotches

genotype: cc phenotype: straight

genotype: Tt phenotype: has tail

genotype: Ss phenotype: sharp teeth

genotype: FF' phenotype: three toes

genotype: ww phenotype: white

genotype: YY phenotype: pointy

genotype: nn phenotype: two ears

genotype: Ll phenotype: long

Explanation: hope this helps (the uppercase letters are dominant genes. the lowercase letter are recessive genes. for a recessive gene to show up in a phenotype you need 2 lower case letters such as cc or ss. for a dominant gene to show up in phenotype you need either 1 or 2 uppercase letters such as Cc or SS. Codominant genes present both colors in the phenotypes i.e. a brown and white cow. incomplete dominance is when neither gene is dominant so a mix of the 2 are present in the phenotype i.e. a pink rose. A regulatory gene controls the expression of a gene

What occurs when a coordinate covalent bond is formed between nitrogen and hydrogen in the ammonium ion, NH4+?

NeX [460]

Covalent bonds are formed when electrons are shared between elements that are nonmetals. The ammonium ion, NH+4 , would have covalent bonds because both nitrogen and hydrogen are nonmetals. ... So, the bond between this particular hydrogen atom and the central nitrogen is a dative covalent bond.

Match these items. 1. moles per liter of solution solute 2. spreading out Keq 3. substance being dissolved diffusion 4. general

Degger [83]

Answer:

1. moles per liter of solution - Molarity

2. spreading out - diffusion

3. substance being dissolved- solute

4. general equilibrium constant - Keq

5. the substance doing the dissolving in a solution - solvent

6. solubility product constant - Ksp

Explanation:

Number of moles of substance being dissolved in one liter of solution is defined as molarity

Solute is the substance which is dissolved and solvent is the substance into which the solute is dissolved. For example salt is solute and water is solvent.

Ksp defines the solubility product constant which indicates the equilibrium between a solid and solution and the number of ions of solid required to achieve this equilibrium.

Keq depicts the scenario where reactant and product concentrations are constant in a chemical reaction.

Hence, the correct match is

1. moles per liter of solution - Molarity

2. spreading out - diffusion

3. substance being dissolved- solute

4. general equilibrium constant - Keq

5. the substance doing the dissolving in a solution - solvent

6. solubility product constant - Ksp
