Isolation is defined as the ecological, anatomical, physical or functional barriers that prevent reproduction between individuals of different species. In the specific case, it refers to a mechanical isolation is defined as the lack of a correspondence between the structure of the genital organs, in the specific case, either the isolation because of having differences between the means of pollination.

Lipophilic hormones function by activating cAMP.
AveGali [126]

Answer:

Option B

Explanation:

Water soluble hormones associate with the G protein of cAMP. This G protein is intra-cellular i.e found inside the cell.  

However in case of lipid derived hormones, the hormone has to diffuse through the cell across the plasma membrane to bind to DNA or the intra-cellular receptors.This regulates the gene transcription and induces protein production that affects the cell functioning for a long time.

Hence, option B is correct

BLUEFIN TUNA: replace with pole or troll-caught Yellowfin tuna, Albacore tuna, Wahoo
Bluefin is the king of the sea. It is the fattiest, richest fish in the sea. Bluefin’s unique flavor contributes to its great appeal. However, we have eaten our way through this species’ ranks and have forfeited our ability to consume this fish. It is a taste that may be lost for many generations to come, maybe forever. However, in most preparations Bluefin can be substituted by pole or troll-caught Yellowfin tuna which, although not quite as elegant, is a great eating experience. For preparations such as grilled tuna, try to seek out pole or troll-caught Albacore or even the tuna cousin Wahoo.

ATLANTIC FARMED SALMON: replace with Wild Alaska Salmon
Substituting for farmed Atlantic Salmon is easy: look for the great quality salmon options from Alaska. All five species of Salmon from Alaska are great stand-ins for farmed salmon. Experiment with the different species to find the one that you like the best. King Salmon is the richest, Sockeye the gamiest, Coho the most balanced, Pink the lightest, and Chum is the most similar to farmed Atlantic Salmon in flavor.

IMPORTED SHRIMP: replace with Oregon Pink shrimp, Alaska shrimp species, or some U.S. farmed shrimp
There are some FANTASTIC shrimp out there that nearly no one knows about. Oregon Pink Shrimp are a delicious product that is very inexpensive and very convenient. Available all year round as a frozen product, these work well in soups, salads, cocktails, sandwiches, nearly every preparation you can imagine. They are smaller than the warm water shrimp but are clean and sweet in flavor and a real treat. Alaska coonstripe, northern and sidestripe shrimp, and spot prawns are all rated “green”. Coonstripe shrimp and spot praws are caught with pots/traps, unlike most shrimp which are caught with destructive bottom trawls. There are some farm raised shrimp options available from U.S. producers which are great eating. They are only a little more expensive and you can eat well knowing that you are supporting not only eco-friendly practices but also helping to create jobs for American
Are the substitutes or alternative products more or less expensive

If you walk through a busy crowd and feel a few different people bump and push past you as they walk by, which skin receptors wo
Likurg_2 [28]

Answer:

Mechanoreceptors would be activated

Explanation:

The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.
