You recently identified a molecule that you believe is a primary messenger for a signal transduction mechanism. All you know about this ligand is that it is hydrophilic. Where would you expect to find initial interaction of the molecule with its receptor
Answer:
Receptor on the outer cell surface.
Explanation:
Hydrophilic signal molecules are the water soluble molecules, they are polar polar and therefore cannot pass through the non-polar center of the plasma membrane without any mediator. Water-soluble ligands bind to the extracellular domain of cell surface receptors. Signal molecules cannot enter the cell and thus plasma membrane receptor is required. Plasma membrane receptor form an important class of integral membrane proteins that transmit signals from the extracellular space into the cytoplasm. This group of signal molecules is quite diverse and most are based on amino acids. In some cases the unmodified amino acid is the signal molecule, in others the amino acid is modified into a derivative and in still others amino acids are combined into peptides and proteins.

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.

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.

¿Podrá la planta producir frutos dentro de una caja oscura?
Answer:
No.
Explicación:
No, la planta no podrá dar fruto en una caja oscura porque para su crecimiento la planta necesita luz solar y sin luz solar no se produce fotosíntesis y sabemos que en el proceso de fotosíntesis, las plantas preparan su propia comida y crecen en tamaño. Este proceso de fotosíntesis solo ocurre en presencia de luz solar, por lo que en la oscuridad no hay luz solar, por lo que no se produce la fotosíntesis y la planta morirá.
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.

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.

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

Answer:
the first one is Antigens and the second one is Antibodies
Explanation:
Antigen is usually present on the blood that determine the person’s blood type. While antibodies in the blood attack foreign blood not compatible with the antigens on the blood.
What are antigens?Blood group antigens seem to be either sugars or proteins that bind to various components of the red blood cell membrane. The antigens of the ABO blood group, for example, are sugars.
Whereas antibodies are present in the blood that determines certain antigens present in the blood that are non compatible.
