Answer:
Conversely, exhalation moves the diaphragm up into the chest cavity and reduces the space in it. This forces the air, which is dense with carbon dioxide at that point, out of the lungs and windpipe. It then exits the body either through the nose or mouth. Usually, this requires no physical effort from the body.

So its A
Since photosynthesis primarily takes place in the leaves, it is essential that glucose can be transported out of the
cell to other parts of the plant. The selectively permeable plasma membrane only allows certain molecules to
cross freely through the phospholipid bilayer.
Is glucose a molecule that is allowed to cross the selectively permeable membrane freely?
Answer: A
No, glucose passes through a channel protein with the concentration gradient via facilitated diffusion.

Many people feel the use of stem cells has great potential for scientific and medical progress, while others have been opposed to it. Today there is a great deal of debate about stem cell research using pluripotent stem cells from an embryo. Provide an argument for people in favor of continuing stem cell research. Include in your answer the uses of stem cell research and a suggestion for obtaining a source of stem cells without risk to life. (2 points)
Answer:
Stem cells can benefit humanity in a variety of ways, one, being the ability to develop into another cell. This is remarkable for people who have diseases and or health issues, requiring them to replace cells that they lack. Not only that, but they help treat diseases like stroke, heart disease and diabetes.
Feedback is always appreciated. Hope this helps you.
please what are the major branches of biology
Answer:
Botany, zoology, and microbiology.
Explanation:
1.The open area of DNA where replication or transcription can take place is called A.replication Bubble B.replication form c.replication strand d.replication origin
2. Once the two strands of DNA are separated, what prevents them from assuming their double- helical shape? A.Other proteins hold the strands apart B.They are too far away from each other C.Each strand has opposing charges, which keep them repelled D. All of the above
3.How does DNA polymerase move along each strand of DNA? A.Both move towards the replication fork B.Both move away from the replication fork C.One moves towards from the replication fork and the other moves away from it D.There is only one DNA polymerase on the DNA at a time
4.How can each copy of DNA at the end of replication be compared? A.Each copy is identical to each other B.Each copy is different from each other C.They are 90% similar D.They are 50% similar
5.In the event of a mismatched nucleotide , which molecule is able to backtrack , "proofread ," and correct the nucleotide sequence? A.DNA Proofreadase B.DNA Polymerase C.DNA Helicase D.DNA Primase
Answer:
1) Transcription Bubble.
2) Replication Forks
3)
Explanation:
1) The region of opened- up DNA is called a Transcription Bubble. In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complentary RNA transcript.
2) The Replication Forks hold the 2 separated strands of DNA apart, preventing then from assuming their double helix shape... in order to replicate all your DNA its faster to replicate DNA if your doing it in many different areas at the same.
3)Since DNA polymerase requires a free 3` OH group for initiation of synthesis, it can synthesize in only one direction by extending the 3` end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3`-5` direction, and the daughter strand is formed in a 5`-3` direction.
I don't know 4 and 5
The answers to the following questions are:
Replication bubble.Replication fork One moves towards from the replication fork and the other moves away from it..Each copy is identical to each otherDNA PolymeraseWhat is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
A particular kind of enzyme called DNA polymerase (DNAP) is in charge of creating fresh nucleic acid molecules that are copies of the original DNA. Polymers are huge compounds consisting of smaller, repeating units that are chemically linked to one another. Nucleic acids are polymers.

"What would railroads do if every state had different requirements for smokestacks or track width?"
Answer:
The train will move on the roads.
Explanation:
If every state had different requirements for smokestacks or track width, the trains should be run on the roads because if there is different requirement for track width, it is impossible to run same type of train on these tracks. One another act will be done and that was to make different types of trains for each state so that they can move on the tracks. But it is impossible for having different track width, it must be of same width.
Use Demetri's results to explain how temperature affects enzymes
Answer:
As with many chemical reactions, the rate of an enzyme-catalysed reaction increases as the temperature increases. However, at high temperatures the rate decreases again because the enzyme becomes denatured and can no longer function. ... As the temperature increases so does the rate of enzyme activity.

What formed between Australia and Antartica? What was the result of this?
Describe the events that occur during the cell cycle. Include what happens in each of the following stages: interphase, mitosis, cytokinesis.
Answer:
Cell cycle or cell division refers to the series of events that take place in a cell leading to its maturity and subsequent division. These events include duplication of its genome and synthesis of the cell organelles followed by division of the cytoplasm.
interphase-During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
mitosis-In cell biology, mitosis is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.
Cytokinesis-Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis. In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half.
