The probability that Phil and Claire's next two children will both have Tay-Sachs is 6.25%.
Both Phil and Claire are carriers of the Tay-Sachs gene, meaning they each have one normal copy of the gene and one mutated copy. When two carriers have a child, each child has a 25% chance of inheriting two copies of the mutated gene and therefore having Tay-Sachs. The probability of having two children with Tay-Sachs in a row is (0.25) * (0.25) = 0.0625, or 6.25%. This means that there is a 6.25% chance that their next two children will both have Tay-Sachs.

How do you classify amino acids as acidic basic neutral polar or neutral nonpolar?
According to the characteristics of the side chain, each amino acid is categorised. The groups are classified as being polar (hydroxylic, amidic, sulfur-containing), nonpolar (aliphatic and aromatic), acidic, or basic.
You can categorise amino acids as nonpolar, polar acidic (also called acidic), polar basic (often called basic), or polar neutral by using the following rules, with two exceptions. We'll look at two outliers, but keep in mind that the change from nonpolar to polar neutral occurs gradually (like the colours of a rainbow), so other sources may classify amino acids differently. There are nine nonpolar amino acids, and they all have aromatic rings or aliphatic (hydrocarbon) chains. The side chain of polar acidic amino acids (2) has a carboxylic acid (or carboxylate) group (R group).

the genetic code is: redundant. a quadruplet code. comprised of codons which usually differ at the first position.
Codons usually differ at the first position, which provides the opportunity for subtle changes in the genetic code to occur.
The process by which data encoded in genetic material (DNA or RNA sequences) is converted into proteins is governed by the genetic code. It is how the body transforms the DNA instructions into the constituent parts of proteins. Codons, which are sequences of three nucleotides, make up the genetic code (the building blocks of DNA). Twenty amino acids can be coded for by each of the 64 available codons.
Due to the redundancy of the genetic code, many codons can encode the same amino acid. Redundancy makes it possible for changes in codon usage to occur without having an effect on the finished protein, providing some evolutionary flexibility. Similar to a quadruplet code, each codon in the genetic code is made up of four nucleotides.

A substance is moved ______ its concentration gradient using the energy of ______ .
A substance is moved against its concentration gradient using the energy of an electrochemical gradient.
The cell must employ energy to transfer substances against a concentration or electrochemical gradient. This energy is derived from adenosine triphosphate (ATP), which is produced during the cell's metabolism.
Pumps are active transport systems that function against electrochemical gradients. Small particles are continually passing across plasma membranes. In the face of these passive motions, active transport maintains ion and other chemical concentrations required by live cells.
These processes may use a large portion of a cell's metabolic energy supply. For example, the majority of a red blood cell's metabolic energy is utilized to maintain the cell's essential balance of external and internal sodium and potassium levels.
Because active transport systems rely on a cell's metabolism for energy, they are vulnerable to various metabolic toxins that disrupt ATP supply.
There are two ways for transporting tiny molecules and materials with low molecular weight. Primary active transport transports ions across a membrane and generates a charge differential across the membrane, which is directly dependent on ATP.
Secondary active transport is the movement of material caused by the electrochemical gradient generated by primary active transport and does not require ATP directly.
