Answer:
Synaptic cleft
Explanation:
Synapse is the region where the impulse is conducted between two neurons. This occurs because two neurons are in maximum possible proximity to each other at the synapse.
However, there is no physical contact between two neurons even at the synapse. And a small space is present between two neurons at synapse. This gap is called the synaptic cleft. The neurotransmitters are released in this cleft.
Answer:
The answers are Flagella and Cilia.
Explanation:
Two different kinds of appendages may be found on eukaryotic cells that enable them to move. <u>Flagella</u> are long slender locomotor appendages that are usually single and few in number, whereas <u>cilia</u> are appendages that are numerous and short. These two differ on the length and amount.
Answer: Low, High, Lac repressor
Explanation:
The expression of the lac structural genes is low when lactose is absent from the culture medium and is high when lactose is added, because lactose binds to the lac repressor and inactivates it.
When Lactose is present the lac genes is expressed because the substrate lactose act as inducer and binds to the lac repressor and inactivate it. So the gene is expressed.
But in the absence of lactose, the lac repressor binds the DNA and prevent the expression of the lac genes
The correct answer is convection because the campfire warms the air around the person.
Convection refers to the transfer of mass motion of a fluid like water or air when the heated fluid is made to be carried away from the heat source, that is, carrying energy with it. Convection takes place when particles with an ample of heat energy in a gas or liquid move and occupy the place of constituents with less heat energy.
Heat energy is conducted from hot places to cooler places by the process of convection.
