B = adds nucleotides
A = unwinds the DNA
C= joins Okazaki
D = tells where to build
C cause they won’t be identical to the parent since they are reproducing sexually
Answer:
The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport
Explanation:
The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.
Most of the digestion and absorption in the small intestine is accomplished by the duodenum; the longest portion of the small intestine is the ileum.
<h3>What is Digestion and Absorption?</h3>
Digestion stands for the complex function of turning the food you eat into nutrients, which the body utilizes for energy, growth, and cell repair required to survive. The digestion process also concerns creating waste to be eliminated.
Digestion stands for the breakdown of extensive insoluble food molecules into small water-soluble food molecules so that they can be immersed in the watery blood plasma. In particular organisms, these smaller substances exist absorbed via the small intestine into the bloodstream.
Absorption exists as a physical or chemical phenomenon or a procedure in which atoms, molecules, or ions penetrate some bulk phase – liquid or solid material. This is a separate process from adsorption since molecules undergoing absorption stand taken up by the volume, not by the surface.

Answer:
III-6
Explanation:
Obligate carriers, or obligate heterozygotes, are those individuals that may be unaffected clinically, but must possess a copy of the mutant gene. For autosomal recessive conditions, obligate carriers can be the offspring of a parental mating of two carriers (50% of offspring will also be carriers). They can also be produced by a parental mating of a carrier by an affected individual (50% of offspring will be carriers).
