Answers
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.
Thus, the answer for blank 1 is antigen, and for blank 2 is antibody.

You are comparing two samples of the octopus genome, one from an octopus that can make ink (sample 1), and one from an Octopus that can't
make ink (sample 2). You notice the one who can't make ink has a mutation Sample 1: ATTACAGTACTGGCA Sample 2: ATTACAATACTGGCA
Looking at the sequences carefully you determine it is a
mutation
A. Insertion
B. Substitution
C. Deletion
D. Inversion
Answers
Substitution Mutation
Explanation:
It can’t be deletion or addition as the base pairs of DNA haven’t shifted to the right or left.
If they had the second sequence would have an extra/one less base pair which isn’t the case.
It can’t be an inversion, as that’s where the base pairs from the opposite DNA strands are inverted/switched.
If it was inversion, you would have had a C instead of an A for Sample 2.
This is due to complementary base pairing where guanine bind with cytosine and adenine binds with thymine.
Therefore, this only leaves substitution as a viable answer.

Answers
Answer:
its b i took the test
Explanation:
Subduction describes convergent boundaries.
What is convergent boundaries?Lithospheric plate borders that are convergent are those where the plates are moving in the same direction. These regions' plate clashes have the potential to cause earthquakes, volcanic eruptions, and crustal deformation.
The thicker, less dense continental plate pushes aside the thinner, more dense oceanic plate when the two plates contact. Subduction is the process by which the oceanic plate is pressed into the mantle.
The oceanic plate is pushed into regions with increasing temperatures as it falls. Materials in the subducting plate start to approach their melting temperatures and partial melting starts to take place at a depth of around 100 miles (160 km).
Therefore, Subduction describes convergent boundaries.

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.
Answers
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

Answers
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?
Answers
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:
The correct answer is - option C.
Explanation:
A longitudinal wave with higher vitality have more noteworthy plentifulness. Abundancy is the separation between the covering and trough of the wave. The crust is the topmost layer of the wave while trough is present at the bottom portion of the wave.
In the event that the separation among crust and trough of the wave is higher so the amplitude is likewise more prominent and we can say that the wave contains a high measure of vitality and the other way around. The state of the structure of the wave simply like a hill.
