Answer:
CO2 + H2O ---SUNLIGHT--------> C6H12O6 + O2
Explanation:
In the process of photosynthesis, carbondioxide reacts with water molecules in the presence of sunlight forming glucose molecules and oxygen gas. The carbondioxide enters the plant body through small openings called stomata, these stomata opens when there is sunlight whereas water enters the plant body through roots from the soil and reaches to the leaves. In leaves both combine produces glucose which can be stored in different parts of the body and some oxygen is used by the plants in the process of respiration and extra is released through stomata.

The amphibian heart has a single, undivided ventricle, two atria, a sinus venosus, and a Conus arteriosus. Their sarcopterygian ancestors had hearts with all of these chambers, but the ventricle was partially divided and probably aided in separating pulmonary and systemic circulatory circuits. Check the following statements that could help us understand why amphibian evolution resulted in the loss of the partial ventricular septum.
A .The loss of the ventricular septum probably occurred because blood returning to the heart of amphibians bypasses the ventricle being shunted from the sinus venasus and right atrium directly to the pulmonary artery and lungs.
B. Loss of the partial ventricular septum reflects the fact that blood returning to the heart from the systemic circuit is often highly oxygenated because many amphibians rely on cutaneous and buccal gas exchange, as well as pulmonary gas exchange, much of the time.
C. Mixing of blood from the lungs with blood from the body in the ventricle is not a problem. Loss of the partial ventricular septum is not a problem because the spiral valve keeps systemic and pulmonary blood separate within the ventricle.
D. The Conus arteriosus of the amphibian heart receives blood from the right atrium and passes the blood on to the pulmonary circulation. This keeps oxygenated and nonoxygenated blood separate.
E. The slightly asynchronous contraction of left and right atria help keep systemic and pulmonary circuit blood separated in the ventricle.
Answers
Answer:
D. The Conus arteriosus of the amphibian heart receives blood from the right atrium and passes the blood on to the pulmonary circulation. This keeps oxygenated and nonoxygenated blood separate.
Explanation:
The conus arteriosus plays an important role in directing blood into the correct arterial arches in amphibian which keeps oxygenated and nonoxygenated blood separate from one another. The Conus arteriosus of the amphibian heart receives blood from the right atrium chamber of heart and passes the blood on to the pulmonary circulation which keeps oxygenated and nonoxygenated blood separate from each other and there is no need for partial ventricular septum.

Answers
Answer:
1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.
2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.

I did the science moon phases for this! I would explain if it showed the graph and everything.
Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.

6. Compare the DNA of an offspring to the DNA of its parents.
Answers
Answer: In DNA the parent duplicates itself through a process known as mitosis. Any offspring is going to have the same exact DNA as the parent. (same characteristics, everything).
The comparison of the DNA of an offspring to the DNA of its parents is determined by the fact that every offspring gets 50% of its genome from each parent, but it is always a different 50%.
How does the DNA of parents compare to that of offspring?In the process of sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote. In other words, an offspring inherits half of the genetic material from each parent. The children resemble their parents, but they are not identical to them.
During the process of meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets. Due to this, the difference in the genetic material or DNA sequences is occurred due to the process of variations between them while DNA copying.
Therefore, the comparison is made due to the mechanism through which every offspring gets 50% of its genome from each parent, but it is always a different 50%.

thankshope it helpsThe EKG is hooked up, and Mr. M's trace looks very abnormal. His heart rate is low. The T wave, which indicates repolarization of the ventricles, is unusually large and pointed and the QRS wave, which indicates the depolarization impulse’s passage through the ventricles, is widened or slowed. "That's a classic EKG for hyperkalemia (high blood potassium)!" The doctor gives Mr. M an injection of calcium gluconate. Calcium ions block the Na+ channels on nerve and muscle cells. How will this help counteract the effects of high blood K+? g
Answers
Answer:
This question lacks options, options are: Mr. M's cells are depolarizing too easily. Blocking Nat channels will make it harder for them to depolarize, bringing their sensitivity back to normal O Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Kt channels can stay open and his cells can repolarize properly. Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Na /K+ ATPase can move Kt out of the cell effectively O Blocking Na* channels cannot help- it will only make his cells fire less, and he already has a weak heartbeat. Mr. M's cells are not repolarizing properly. Blocking Nat channels will help them repolarize normally, bringing their resting potential back to normal.
The correct answer is ''Mr. M's cells are depolarizing too easily. Blocking Na+ channels will make it harder for them to depolarize, bringing their sensitivity back to normal.''
Explanation:
Calcium administration is an emerging treatment modality aimed at restoring the transmembrane electrical gradient of cardiac myocytes. It probably achieves this goal by reducing the resting membrane potential of cells. Calcium antagonizes the effect of hyperkalemia on cardiac conduction, that is, it antagonizes the effects of K on the heart. Its onset of action is immediate, in a few minutes. Calcium gluconate antagonizes the excitability of the cardiac membrane, that is, it decreases the excitability of the membrane and it does not affect serum levels, it is generally accepted that calcium should be administered when there are ECG changes associated with hyperkalemia.

g The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. it rises to the surface and absorbs wavelengths needed by aquatic plants it causes the water to become murky it decomposes endothermically causing the temperature of the water to decrease below the limits within which most aquatic organisms can live it causes oxygen depletion in the water it causes death of bottom dwelling organisms because it agglutinates and settles to the bottom, poisoning bottom dwelling organisms
Answers
Answer:
It causes oxygen depletion in the water
Explanation:
When the amounts of organic matter in the water are significant, the activity of aerobic bacteria and other decomposers increases.
Organic matter suffers decomposition in the presence of oxygen. Microorganisms degrade it while consuming dissolved oxygen in the process. Bacteria show fast and exponential growth, so the more organic matter, the more aerobic bacteria, and the less available oxygen in the water.
Organisms that usually inhabit these waters are affected by the lack of oxygen. Plants, algae, animals, and other invertebrates that need it to survive, find themselves limited in these environmental conditions. Eventually, they dye and contribute with more organic matter.
Little by little, sedimentation begins caused by the death of vegetables and animals, sinking in the bottom.
When oxygen disappears, anaerobic bacteria grow and act, producing fermentation.
