Answer:
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then, during DNA replication, the two strands in the double helix separate.
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
2. The small molecules move into the?
Facilitated diffusion, like passive diffusion, involves the movement of molecules in the direction determined by their relative concentrations inside and outside of the cell. ... They then undergo conformational changes that allow the molecule to pass through the membrane and be released on the other side.
Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion (or simple diffusion), osmosis, and facilitated diffusion

What is octopus?Octopuses are highly clever creatures that have mastered camouflage and have developed a variety of cunning strategies over tens of millions of years to evade or prevent potential predators. They are able to blend in with their surroundings' colors and textures, enabling them to remain undetected.
Octopuses can quickly flee if a predator approaches by launching themselves forward by ejecting water from a muscular tube known as a siphon. Additionally, octopuses have the ability to expel a cloud of black ink that hides them and impairs an intruder's ability to smell.
Therefore, The structural adaptation an octopus would use for movement is suction cups on limbs.

How might the interdependence of organisms in a specific habitat be
helped or harmed as a result of changes in the ecosystem over time?
Changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.
What is the effect of change in ecosystem over time on the interdependence of organisms in a specific habitat?Changes that occur in an ecosystem may occur as a result of natural or man-made causes.
Changes in an ecosystem may have positive or negative effects on the interdependence of organisms in a specific habitat.
For example in an aquatic habitat where certain species of fishes like sharks depends on smaller fishes like salmon to survive, if humans were to reduce the salmon population by overfishing, the sharks will be negatively affected as they may have to migrate to new hunting grounds.
However, some other fishes that are prey to shark may be able to grow more with the reduction on shark population in that area.
Therefore, changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

The kidneys help to regulate the salt balance of the body. Normally, more than 99% of the sodium filtered at the ____________ is returned to the blood. Most of this sodium is reabsorbed at the ____________ .
Normally, more than 99% of the sodium filtered at the glomerulus is returned to the blood. Most of this sodium is reabsorbed at the proximal tubule.
The glomerulus are enveloped networks of capillaries found in the nephron of the kidney.The glomerulus are responsible for filtering and purifying blood plasma (such as sodium, phosphorus and potassium).The efferent arteriole emerges from each glomerulus, from which arises a network of peritubular capillaries and descending vasa rectus.Efferent fibers stimulate renin release and proximal tubular sodium reabsorption, thereby affecting renal and systemic vascular resistance.Reabsorption of the initial charge of the main solutes takes place in the proximal tubule.The reabsorption of water throughout the nephron follows the reabsorption of solutes.67% of the filtered water is reabsorbed in the proximal tubule by osmosis, with the reabsorption of sodium coupled to other solutes at this level being the generator of the osmotic gradient.Therefore, we can conclude that the sodium filtered at the glomerulus is returned to the blood. Most of this sodium is reabsorbed at the proximal tubule.

I need help question 14
Answer:ok
Explanation:
The sequence by which electrons travel downhill during aerobic respiration. The se sequence has NADH, oxygen chain of transportation of electron, food and NAD.
Respiration (both aerobic and anaerobic) begins with glycolysis in the cytoplasm of a cell;
1 glucose molecule (C₆H₁₂O₆) is converted into 2 molecules of pyruvate in a 10-step process, consuming 2 ATPs and yielding 4 ATPs;
Additionally, 2 NAD+ molecules are reduced to NADH molecules;
In aerobic respiration, each pyruvate molecule then goes through the link reaction, getting converted to acetyl co-A in the mitochondrial matrix, producing 1 CO₂ molecule and 1 reduced NADH molecule;
Acetyl co-A then enter the Krebs or tricarboxylic acid cycle (TCA) where 2 CO₂, 1 ATP, 3 NADH (by reduction of NAD+) and 1 FADH₂ molecules are produced;
The NADH and FADH₂ molecules produced are electron carriers required for the electron transport chain (ETC);
The electron transport chain consists of 4 proteins within the inner mitochondrial membrane which are involved in the production of ATP by oxidative phosphorylation;
The first protein (C1) is responsible for oxidising NADH to NAD+, releasing energy used to generate the proton motive force (PMF) by pumping the protons (H+ ions) into the intermembrane space and the electrons released are transferred to a ubiquinone molecule;
The second protein (C2) is responsible for oxidising FADH₂ to FADH, also releasing energy used to generate the proton motive force (PMF) and, similarly to C1, the electrons released are transferred to ubiquinone;
The third protein complex (C3) transfers the electrons from ubiquinone to cytochrome C;
Finally, cytochrome C transfers these electrons to the fourth complex (C4), where they combine with free protons in the matrix and O₂ to to produce H₂0;
The PMF is then harvested via an ATP synthase protein where H+ flood back into the mitochondrial matrix, and the energy released is used to generate ATP from ADP and Pi;
ATP is now ready for use for bodily processes requiring it.
