Answer: Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out
Explanation: All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.

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.

What do coral reefs and estuaries have in common?
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.

At rest the lens of the eye will be more round when the ciliary muscles are contracted true or false
Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.

write out the pathway that a drop of blood takes, starting in the right ventricle. As you describe the path, include the names of the blood vessels and the valves, and indicate if the blood is oxygenated or deoxygenated g
Answer:
The correct answer is - Right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, arteries, arterioles, capillaries, venules, veins, vena cavae
Explanation:
Throughout the vascular system or cardiovascular system, the drop of deoxygenated blood moves through right atrium and right ventricle to the lungs within the pulmonary arteries. Then the oxygenated blood transfers via pulmonary veins t the left atrium of the heart that pumps the oxygenated to the rest of the body by the left ventricle through the aorta.
Arteries help in the flow of the systemic circulation then blood moves from arterioles to capillaries. The deoxygenated blood is returned through the veins to the heart that come to the superior and inferior vena cava and back to right atrium and cirlculation repeat again.

The two elements, in looking at their atoms, have a total of 51 protons between them are Magnesium and Aluminum and Lithium and Scandium so option d. both A and B.
What are protons?
The protons are + charges particles found in the nucleus of the atoms.
NO. of protons in :
Magnesium and Aluminum- Magnesium has total of 12 proton and Aluminum has 13 total protons. Lithium and Scandium- Lithium has 3 and Scandium has 21So total no. of protons= 12+13+3+21= 50.

characteristic could have caused the sharpest decline?
A hibernation during the winter
B mobility on land and in the air
C conversion of sunlight into food energy
D different fur coloring in summer and winter
Answer:
c
Explanation: all other traits are irrelevant and could reply to any part o the food chain, c means that the plats have dropped, meaning that the things that eat the plants wot be able to eat the plants, (primary consumers)and the secondary consumers wont be able to eat the primary consumers,then the tertiary consumers wont be able to eat the secondary consumers. In simpler terms it would cause a chain reaction that would detonate the whole foodchain.

Use the information gathered in the A Three Point Test Cross animation to answer the question. Genes H and K are linked and are known to be 3.5 m.u. apart on the same chromosome. What is the recombination frequency between H and K
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, crossing over or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/loci located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/loci (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.
Refer to the Biochemistry in Focus section of your text for this chapter to answer this question. A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I
Answer:
Complex II
Explanation:
The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.

Explain how the lymphatic system is adapted for the transportation of the lymph
Answer:
The lymph capillaries feed into larger lymph vessels. The lymph vessels that receive lymph fluid from many capillaries are called collecting vessels. Semilunar valves work together with smooth muscle contractions and skeletal muscle pressure to slowly push the lymph fluid forward while the valves prevent backflow.

Answer:
C. Eukaryotic because it has a nucleus
Explanation:
All living organism have been classified into a wide category called DOMAIN, which consists of Eukarya, Prokarya, and Archaea. Living organisms are classified into each of these domains mostly based on whether or not they possess NUCLEUS in their cells.
Domain Eukarya known as Eukaryotes are made up of organisms that possess a membrane-bound NUCLEUS in their cell. According to this question, some students looked at pond water with a microscope and saw both prokaryotic and eukaryotic organisms. The organism displayed in the attached image is EUKARYOTIC simply because it has a NUCLEUS.
