The track the flow of electrons through the ETC.
D. Complex I, Ubiquinone, Complex III, Cytochrome C, Complex IV, Oxygen.
Flow of electrons in ETC:In the mitochondrial ETC, electrons flow when the reduced electron (NADH, FADH₂) are oxidized. In plants and other photosynthetic organisms, an ETC serves to oxidize NADPH. They travel down the electron transport chain, releasing the electrons that they once had. The end result is loads of energy, approximately 34 ATP (energy molecule).
Thus, the track of flow will be: Complex I, Ubiquinone, Complex III, Cytochrome C, Complex IV, Oxygen

The unusual patterns on a silk moths wings are one of the most stunning examples of mimicry in the wild,mimicry can protect the moth?
The question is incomplete. The complete question is as follows:
The unusual patterns on a silk moth’s wings are one of the most stunning examples of mimicry in the wild. Mimicry occurs when an organism develops a physical characteristic or behavior similar to a protective trait in another species. What do you think these moth wings mimic? Why do you think this kind of mimicry can protect the moth?
Answer:
The silk moth's mimic the physical characteristics such as changes in wings pattern that resemble another moth species that is dangerous or unpalatable to predators.
This unusual change in wings pattern provide camouflage to the silk moths and prevent predators. Predators get confuse because of the mimic spcies and consider them as toxic or untasty and won’t attack.
Answer:
The moth wings actually look like the eyes of a much larger animal. This mimicry may protect the moth from predators.

1. Which of the following is NOT a result of convection current? a) The air in a room is cooled by an air conditioner b) Wind blows towards the beach from the sea. c) The water in a kettle is heated and boils d) The wax covering an iron rod melts when the rod is heated.
Answer:
its D
Explanation:
because conduction happens through solids and the others are obviously conventional current
The wax covering an iron rod melts when the rod is heated ( D ) is not a result of convection current
Convection is the transfer of heat energy from an area of higher concentration to an area of lower concentration and it occurs in fluids and gases. while conduction is the transfer of heat energy from one object to another through the direct contact of the objects and this occurs between solids.
The transfer of heat from the heated rod to the wax covering occurs because of the direct contact the wax has with the heated rod therefore it is conduction and not a convection current.
Hence we can conclude that The wax covering an iron rod melts when the rod is heated is not a result of convection current

A female had tubular pregnancy and had to remove her oviducts. Will this affect her in anyway with respect to reproduction ? justify?
Reproduction will be highly affected.
Since there are two oviducts one will be removed as a result of the ectopic pregnancy.
Hence, there will be a defect in the carrying of the ovum from the ovary to the uterus. There will be delivery of the ovum only in the the unaffected oviduct. This can lead to non-fertility.
Ectopic pregnancy is a condition in which there is an implantation of the zygote in a location other than the the uterus.
What is the correct order of blood flow from the heart to the lungs in the fetal circulatory system? a. Ductus venosus, heart, vena cava, ductus arteriosus, arteries b. Vena cava, ductus venosus, heart, ductus arteriosus, arteries c. Ductus venosus, vena cava, heart, ductus arteriosus, arteries d. Vena cava, heart, ductus venosus, ductus arteriosus, arteries
Answer:
When the blood enters the right atrium, most of it flows through the foramen ovale into the left atrium. Blood then passes into the left ventricle (lower chamber of the heart) and then to the aorta, (the large artery coming from the heart).
Explanation:
Answer:c.
Ductus venosus, vena cava, heart, ductus arteriosus, arteries
Explanation:
The circulatory system consists of the heart and blood vessels. In a fetus, the circulation of blood is different from circulation after delivery largely due to the fact that the lungs are not in use, rather, the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.
Blood from the placenta is carried to the fetus by the umbilical vein. While some of this blood enters the fetal ductus venosus and is carried to the inferior vena cava, some others enter the liver. The blood from the inferior vena cava then moves into the right atrium of the heart. The foramen ovale, an opening between the right and left atrium in the fetus directs most of the blood flow from the right into the left atrium, thereby, bypassing pulmonary circulation. Most of the blood from the right atrium flows into the left ventricle and is pumped through the aorta to the rest of the body.
Some of the blood from the right atrium however, enters into the right ventricle and is pumped into the pulmonary artery. The ductus arteriosus which is a special connection between the pulmonary artery and the aorta in a fetus, directs most of this blood away from the lungs and into the arteries.
Which two characteristics describe all animals? multicellular and symmetrical multicellular and asymmetrical heterotrophic and multicellular heterotrophic and unicellular
Answer:
heterotrophic and multicellular
Explanation:
All animals are heterotrophic and multicellular. Heterotrophic means that the animals are unable to manufacture their own food. The animals are said to be heterotrophic because unlike plants, they cannot manufacture their own food. They depend on plants and other sources to derive nutrition and energy. Multicellular means made up of many cells. Animals are said to be multicellular because they are made up of different cells.
Answer:
All animals are heterotrophic and multicellular.
Explanation:
All animals are multicellular, they're not just made of one cell.
All animals are heterotrophic, they cannot make their own food like plants so they must rely on eating other organisms for food.
Also, the other answers don't fit.

The word anabolism refers to constructive, buildup, or synthesis reactions while the word catabolism refers to destructive, breakdown, or digestive reactions. What does it mean to say that in a cell, catabolism fuels anabolism?
Answer:
Anabolic reactions need energy.
Explanation:
Anabolic reactions (like the build up of fatty acids) are active processes and need energy. Catabolic processes like respiration will provide the ATP required to build up macromolecules. Thus, catabolism fuels anabolism.

Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron?
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.
This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.

Answer
Mice share a common ancestor with humans, homologousExplanation:
The DNA of humans and mice is almost 92% similar. This similarity indicates that mice share a common ancestor with humans. Mice have a tail, while humans have a tailbone. The tailbone is a homologous structure in humans.
The existence of similar genes (DNA) and pair of structures (tail and tail bone) between humans and mice is referred to as homology. The tail and tail bone that exist between the different animals are called homologous structures. Homologous structures are similar structures that can be found in different animals, indicating that the animals have evolved from a common ancestor. Homologous structures show a high degree of similarity in form but they may or may not have the same functions in the different animals.
The similarity in the DNA and the structures (tail and tail bones) that exist in humans and mice suggests that the two different specie are connected to a common ancestor.
