what is most likely to happen when water loses heat
Answer:
it will turn to ice
Explanation:
the potential energy in the molecules is reduced and they start to move alot slower, eventually they stick together and form ice
Describe how home heating and cooling has changed over time, and how it has remained the same.
The difference between an open and a closed circulatory system is...
Answer:
In the closed circulatory system, blood is confined to a heart and blood vessels, whereas in an open system, hemolymph (blood) moves from a heart through vessels into interconnected spaces called a "hemocoel."
Explanation:
An open circulation the blood is not blood vessels, it instead is pumped into a cavity called Hemocoel.
A closed circulatory system, the blood is pumped through vessels SEPARATE from the interstitial fluid of the body.

1. What is the purpose of transcription? Why does it have to occur?
Answer:
The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.

how long does it take for mitosis to complete? why will most of the cells you view be in interphase?
Answer:
Mitosis takes about 2 hours to complete :3
Most cells would be viewed in interphase because it's the most important part of the stage where G1, S, and G2 phase are there too :3
Explanation:
:3
The breaking down of glucose into two molecules; anaerobic process. Please help
Answer:
glucose is broken down in ten steps to two molecules of pyruvate which then enters the mitochondria where it is oxidized through the tricaboxylic acid cycle to carbon dioxide and water
Match the following terms describing electrical events with the correct phases of the cardiac cycle.
Question Selected Match
The ventricular muscle cells depolarize at the start of this phase.
During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold.
The ventricular muscle cells repolarize right before this phase.
The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase.
All Answer Choices
A. isovolumetric contraction
B. ventricular ejection
C. ventricular filling
D. isovolumetric relaxation
Answer:
1. Isovolumetric contraction.
2. Ventricular filling.
3. Isovolumetric relaxation.
4. Ventricular ejection.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The following terms describe the electrical events with the correct phases of the cardiac cycle in mammals (human beings);
1. Isovolumetric contraction: The ventricular muscle cells depolarize at the start of this phase. During this phase, the pressure in the atria is lower than the pressure in the ventricles while the pressure in the arteries is higher than the pressure in the ventricles.
2. Ventricular filling: During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold. It causes the atria to contract at the end of the phase.
3. Isovolumetric relaxation: The ventricular muscle cells repolarize right before this phase. During this phase, all of the four (4) cardiac valves are closed while all of the four (4) chambers are relaxed.
4. Ventricular ejection: The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. Also, the atrioventricular (AV) valves are closed while the semilunar valves are open.
Most fossilized bones have undergone the process of
A)unaltered preservation
B)carbonization
C)casting
D)perimineralization
Answer:
D. Perimineralization
Explanation:
After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals, typically silica, into empty spaces, producing a fossil.
