Explanation:
Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.
Answer:
A
Explanation:
The correct answer would be that the sperms are changing chemical energy to kinetic energy.
In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells. Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.
The correct option is A.

According to the body-cover theory of phonation, which part of the vocal fold is not considered to be a portion of the cover
Answer: B. Thyroarytenoid muscle
Explanation:
The options include:
A. Epithelium
B. Thyroarytenoid muscle
C. Superficial layer of the lamina propria
D. Intermediate layer of the lamina propria
The cover-body theory of vocal fold vibration was published by Hurano in 1974 and he described the morphological structure of the vocal folds. He also divided them into the body and cover layer biomechanically.
The main substance of the vocal fold is regarded as the thyroarytenoid muscle. The muscle provides most of the mass of the vocal cord.

Part Two: Position Paper What's your position about building roads in the rainforest? Write a paper that explains your position. Use facts from your research to support your position. How would humans and different parts of Earth be affected by the construction? Is there any argument against your position?
Answer:
We should not be building roads in the rain forest. Some reasons behind this include trees produce oxygen, animals leaving their natural habitat would not survive, and it would only increase pollution. Research states that if pollution increases any more, the Ozone protecting us will deteriorate. Other research states that if animals lose their natural habitat and have to adapt to a new environment, they are not very likely to survive. And not surviving means that the food chain will break, affecting everything above it, and that could also include us. This concludes why we should not build roads in rain forests.
Explanation:
Sorry if its short, but here <3
No roads should be build in the rainforests.
What do you mean by rainforests?
"A luxuriant, dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall."It's a moisture dependent vegetation.Why no roads?To build a road a vast area full of vegetation will be cut down.This will adversely affect the climate and habitats of organisms living there.This will also result in scarcity of rainfall.This results in interference of humans on the habitat of that area.Hence, building of road should be avoided in rainforests.

After nervous stimulation stops, calcium ions returning to the sarcoplasmic reticulum prevent ACh in the synaptic cleft from continuing to stimulate contraction True False
Answer:
False.
Explanation:
Neurotransmitter release occurs from the nervous terminal or varicosities in the neuronal axon. When an action potential reaches the nervous terminal, the neurotransmitter is released by exocytose. The molecule binds to its receptor in the postsynaptic neuron, triggering an answer. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic response. To stop this process the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
• Enzymatic degradation/deactivation: There are specific enzymes in the synaptic space, which are in charge of inactivating the neurotransmitter by breaking or degrading it. The enzyme acetylcholinesterase prevents ACh from continuing to stimulate contraction.
• Reuptake: Receptors located in the presynaptic membrane can capture de molecule to store it back in new vesicles for posterior use. These transporters are active transport proteins that easily recognize the neurotransmitter.

7. Give two examples of biochemical reactions and explain how an organism uses ATP within the reactions.
Answer:
Because of its energy supply, ATP is necessary for all biological reactions.
ATP is employed both in salt and potassium pumping operations and in the cellular breathing mechanism.
Explanation:
The breakdown of glucose, which frees the cell's energy for life functions, is an example of a catabolic response. Endothermic reactions are called anabolic processes in organisms. The connection between amino acids and a protein is an example of an anabolic response.
If a cell needs energy, this link breaks into adenosine diphosphate (ADP) and a free molecule of phosphate... With an excess power of the cell, this energy is stored by creating ATP from ADP and phosphate. For any muscular contraction, ATP is needed for metabolic reactions.
-To break down one glucose into pyruvate molecules in Glycolysis 2 ATP molecules 4 ATP molecules are produced for a net addition of 2 ATP molecules.
-An inorganic carbon is converted into sugar by ATP in photosynthesis.
1 poi A student draws a diagram of a plant cell. The diagram is 40mm in width. The plant cell is 0.02mm in width. What is the magnification of the student's drawing? A. 0.005 B. 0.08 C. x200 D. x2000
Answer:
D. x2000
Explanation:
magnification = image(drawing size)/actual size
magnification = 40/0.02
magnification = x2000
The magnification of the diagram is x2000. So, the correct option is (D).
What is Magnification?Magnification is the process of magnifying something. It enlarge the apparent size and not the physical size. This type of enlargement is certainly quantifiable. It also refers to the action of visually enlarging an object with the help of lenses.
This concept exist in two forms-
1. By microscope
It makes small objects appear large
2. By telescope
It makes a distant object which appear closer and the images are more clear and defined.
The formula of magnification represents the ratio of the height of the image to the ratio of the height of the object.
Magnification = image/actual size
For given example, magnification = 40/0.02
magnification = x2000
Thus, the magnification of the diagram is x2000. So, the correct option is (D).

The transcription of genes in E. coli that lack a termination sequence require _______ factor to terminate transcription.
Answer:
rho
Explanation:
The Rho factor is a prokaryotic helicase protein that acts in bacteria to mediate the process of termination of transcription. In Escherichia coli, the Rho factor is a hexameric ring-shaped helicase and each subunit of this factor contains two domains involved in RNA binding and ATP hydrolysis. The Rho factor binds to the transcription terminator site on single-stranded RNA and then continues along the messenger RNA (mRNA) strand until it reaches the RNA polymerase, subsequently triggering its dissociation from the DNA and thus the termination of transcription.
