Answer:
true
Explanation:
Penicillin is a bacteria so it means it causes the production of antibodies which then boost the immune system.
It is like vaccination; small doses of the inactive form of the infection is injected into the body in order for the body to create antibodies resistant to such infection(thereby boosting the immune system).
Hope it helps.
Answer:
atoms
Explanation:
everything is made from atoms
Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.
Answer:
Calcium voltage gated ion channels
Explanation:
There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).
The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles to release acetylcholine via exocytosis into the synaptic cleft.

Answer: D) The lizard and the snake are secondary consumers.
Explanation:
Producers are organisms that, simply put, produce their own food. All photosynthesizing plants are considered to be producers. Animals cannot be producers.
Primary consumers eat producers.
Secondary consumers eat primary consumers.
Tertiary consumers eat secondary consumers, and so on.
The lizard eats a fly, which is a primary consumer. This makes the lizard a secondary consumer.
The snake eats a mouse, which is a primary consumer. This makes the snake a secondary consumer.
A) is incorrect because the hawk is a tertiary consumer.
B) is incorrect because grass is a producer, not a consumer
C) is incorrect because the lizard is a secondary consumer
