Blend the banana peels with coffe grounds and egg shells to make a homemade fertilizer!
<span>Answer
1. electrical signal travels toward the heart
2. signal by the nodes in the atrium</span>
3. the atria contract<span>
</span>4. signal received by the atrioventricular node
5. signal transferred to the ventricles
6. the ventricles contract
Heart has a pacemaker that will continually send a signal. The primary site of the pacemaker is at the sinoatrial node, on the top right atrium. This node will send a signal to atria (which will cause it to contract) and to the atrioventricular node.
Atrioventricular node located between atrium and ventricle. It will send the signal to the ventricle(by the bundle of his) and cause it to contract.
Answer:
Chromosomes contain very large genetic information which would take many hours to replicate with only one origin.
Explanation:
Human cells are eukaryotes, meaning that the genetic information is compressed in chromosomes, that at the same time are contained in the nucleus. As the replication requires all the genetic information to be copied, the length of it would take several hours to complete this task. Therefore, with many origins of replication, this process happens faster and more effectively.
The graph pictured shows bacterial growth, in a petri dish, in which no additional resources are added over time, The graph pictured shows bacterial growth, in a petri dish, in which no additional resources are added over time.
<h3>How does the bacteria actually grow in the petri dish?</h3>
Sterile powdered agar with nutrients can be mixed with moisture, heated and then rushed into empty petri plates or ready-to-use dishes can be purchased.
The undigestible agar is a gelatin-like substance with a semi solid surface on which the bacteria can grow while they engulf the added nutrients
Thus, option "D" is correct.
