Answer:

<em>TO Determine whether Organic or not Just take some crystals on the end of a spatula and then introduce it in a flame, if it is melts or burns without white vapors then it is an inorganic compound and if you see white vapors or smoky vapors, it is organic.

Juliette [100K]

Answer: Both the mouse and human beings are encoding the proteins having similar functions.

Explanation:

The CFTR gene in the mouse and CFTR gene in the human beings encode proteins that perform similar function,this is so because if the results are same then it means that both mouse and human beings are encoding the protein that have similar function.

Option A is incorrect  because both humans and mouse are eukaryotes so they have introns and because of that even if the gene sequences are different they can still encode protein.

Option B is incorrect because  amino acid sequences can be similar inorder to have the similar function. If glutamic acid is replaced by aspartic acid, it won't have different function the function will remain same. So, identical amino acid sequences are not required. They can be similar too.

Based on the concept of the global conveyor belt, what happens to ocean water as it moves from Antarctica to the equator?
marta [7]

What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.

<h3>Concept conveyor belt </h3>

The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.

As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.

Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is  It becomes less dense and rises to the surface.

What property makes phospholipids ideal building blocks for cell membranes?
Papessa [141]

Answer:

<u> They have hydrophilic heads and hydrophobic tails.</u>

Explanation:

Phospholipid membranes are comprised of a chain of lipids. These typically are arranged in a bilayer; the hydrophilic lipid heads are polar, and face outwards, while the hydrophobic tails are polar facing inwards.

The membranes are selectively permeable, and only allow the movement of small, non-polar molecules through the bilayer.
