Ok so answer for 5 would be
5) a mimicry could be a great fully helpful adaption because as an example, the butterfly’s that blend in with trees, or the butterfly’s that look like birds, can either scare away predators or they can blend in.
6) as an example, a blue tongue skink has a blue tongue which is very common in venomous animals. Whenever said skink is threatened, it puffs up, opens its mouth, and hisses. When most predators see the tongue, they assume it’s venomous/poisonous because of the bright color. Another example would be milk snakes who look like coral snakes to scare away predators
For each molecule of glucose consumed, the Krebs cycle occurs: D. twice
1 glucose --> 2 pyruvate, each one entering the Krebs as acetyl-CoA
Answer:
A. Duodenum
Explanation:
Duodenum is the first part of the small intestine which receives bile juice, pancreatic and intestinal digestive juices. The digestive enzymes present in these juices completes the process of digestion.
The lining of the duodenum has numerous finger-like projections called intestinal villi. The villi are specialized to absorb the digested food by providing increased surface area for the process of digestion. Hence, among the given options, the absorption of digested food occurs in duodenum.
You have given no demonstration based on your microscopic investigation so I cant tell you the answer to the question. I will try to help you by elaborating how to decipher..
Three terms hypotonic, hypertonic and isotonic are used when referring to two solutions separated by a selectively permeable membrane.
The hypertonic solution has a great concentration of OAS than the solution on the other side of the membrane. It is described, therefore, as having a great osmolarity. The hypotonic solution has a lower concentration of OAS, or osmolarity, than the solution on the other side of the membrane. When the two solutions are at an equilibrium, the concentration of OAS being equal on both sides of the membrane, the osmolarities are equal and are said to be isotonic.
The net flow of water is from the hypotonic to the hypertonic solution. When the solutions are isotonic, there is no net flow of water across the membrane.
If red blood cells are placed in a solution with a lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell; such a solution is hypotonic to the cells.
So, look at the information and data you have on your microscopic investigation and use these guidelines to tell you which is which.
Answer:
Since boron only has two electron shells, it is about as capable of gaining electrons as it is of losing electrons, so it behaves as a metalloid. The other elements in this group have more electron shells, so it is much easier for them to lose their valence electrons and they behave like metals.
