Answer:
The given blanks can be filled with vesicle, release, and blocking the action of enzymes.
Explanation:
The psychoactive are the drugs, which instigates the discharge of excitatory neurotransmitter as glutamate, and the antipsychotics diminish the excitation of the neuron. The mentioned drugs could enhance the effect of a neurotransmitter by inducing the leak of neurotransmitter due to the dissociation of a synaptic vesicle, by preventing the release of the neurotransmitter from the presynaptic membrane, and by obstructing the activity of the enzymes that usually breaks down the neurotransmitter.
Answer:
b. It allows gas exchange while preventing water loss
Explanation:
Amniotic eggs are the feature of land animals such as reptiles, birds, mammals, etc. The amniotic eggs have four extra-embryonic membranes. This semipermeable protective shell allows the exchange of respiratory gases but does not support the transport of water out of the egg.
The ability to maintain the water inside the egg while permitting gaseous exchange is the specific feature of amniotic eggs and allowed diversification of land animals in the land habitats.
Answer:
Invertebrates
Explanation:
Most of the fossils belong to invertebrates. Invertebrates make around 95% of all the animal species. Invertebrates do not have bones that are present in vertebrates. The soft body parts of invertebrates form impressions and their exoskeletons and shells also form fossils. Bones of vertebrates are scattered after the death of the organisms and makes their fossils rare.
Answer: Heat ---from a warmer substance to a cooler substance
Explanation: Heat can be transferred from a hotter substance to a cooler substance. This can be done through three methods;
Conduction, Convention, Radiation
Conduction- When substance is been heated movement of particles increases causing collision between hotter particles and cooler particles. This continue until the temperature is in equilibrium. Metal is a good conductor of heat.
Convention- It is often associated with liquid and gases. hotter area of liquid moves and meet with cooler liquid. The cooler liquid then takes place of the hotter liquid until equilibrium is attain. This occurs while boiling water
Radiation - It doesn't need a means of transmission. It is gotten from infared emission. Infared emission increases when temperature increases .
