Answer:
A. Neurotransmitters can act as ligands.
B. Acetylcholine is a neurotransmitter. It can bind to an acetylcholine receptor on the surface of a cell. If this receptor is also a sodium channel, we would call acteylcholine a ligand and its receptor a ligand gated receptor.

Explanation:
Neurotransmitter are chemicals that transfer signals between neurons and nerve cells. They control some physical and physiologocal activity such as appetite, food.
Acetycoline is an example of neurotransmitter and it is located in the parasympathetic nervous system. Ligand are substance that form complexes with biomolecule. They serve biological purpose with this biomolecule.
This ligand binds to target site. Neurotransmitter act as ligand by binding to receptor in the postsynaptic neuron and acetycoline a type of neurotransmitter can also serve as ligand they bind to acetycoline receptor on cell surface.
Answer:
Today, one second is defined as “9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom”. That's a mouthful.
Answer:
The answer is A
Explanation:
The road fragmented the habitat and now the turtles are not able to breed
Insects (Insecta) are the most diverse of all animal groups. There are more species of insects that there are species of all other animals combined. Their numbers are nothing less than remarkable, both in terms of how many individual insects, as well as many species of insects that are. In fact, there are many insects that is not very known how to count them all, the best thing we can do is to make calculations.
Approximate scientists who can be as many as 30 million species of insects alive today. To date, they have identified over 1 million. At any time, the number of live insects on our planet is amazingly, some scientists estimate that for every human being alive today, there are 200 million insects.
The success of insects as a group is also reflected in the diversity of habitats in which they live. Insects are more numerous in the land such as deserts, forests and grassland environments. They are also numerous fresh water such as ponds, lakes, streams and wetlands habitats. Insects are relatively scarce in habitats marine, but are more common in the waters brackish, like marshes and mangrove
Good luck!
Answer:
The correct answer is 20 years.
Explanation:
It is given that the growing rate is 2% or 2/100 = 0.02
This rate got increased to 150%
The formula for exponential growth is:
A = Pe^rt
Let the initial population be 100%
150 = 100.e^0.02*t
3/2 = e^0.02t
1.5 = e^0.02t
After taking log from both the sides:
ln(1.5) = 0.02t * ln(e) [ln(e) = 1]
ln(1.5) = 0.02t
t = ln(1.5)/0.02
t = 20.27
Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.
