Land heats and cools more than water because ________.
Land heats and cools more because it has a lower specific heat capacity that water.
To answer the question, we need to know what heat is
What is heat?This is the amount of thermal energy in a body
What is specific heat capacity?This is the amount of heat required to raise 1 kg of substance by 1 °C.
So, the greater the specific heat capacity, the greater he amount of heat required.
Since land which has a specific heat capacity of less than 1 J/g-°C and water which has a specific heat capacity of 4.2 J/g-°C, thus, land heats and cools more because it has a lower specific heat capacity that water.
So, land heats and cools more because it has a lower specific heat capacity that water.

explain how RNA can serve as hereditary information
Answer: Genetic code (genes and genome) and the mechanisms of replication.RNA determines a cell’s function, synthesizing proteins and enzymes. Mutations, changes in DNA instructions, are the molecular basis of evolution. Nucleic Acids are the basis for the storage and transmissions of hereditary information in all cells.
Explanation:
RNA serves as the hereditary information for viruses that lack DNA. Although, typically single-stranded in most cells, in viruses they can be either single-stranded or double-stranded. Double-stranded RNA is an indicator or a viral infection.

write detail note on malaria 2 study
A detailed note on the malaria is discussed below:
What is malaria?A parasite that frequently infects a particular species of mosquito that feeds on people can result in the serious and occasionally fatal disease known as malaria. Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Humans can contract four different types of malaria parasites: Falciparum Plasmodium, P.
Female Anopheles mosquitoes carrying the Plasmodium parasite bite people to feed their own eggs, which is how the parasite is propagated. An infected mosquito injects sporozoites, or early stages of the parasite, into the host's bloodstream while it consumes its prey (often between twilight and sunrise). The sporozoites are transported by the blood to the liver, where they develop into schizonts, which are a type of parasite. Each schizont multiplies into thousands of merozoites throughout the course of the following one to two weeks. The merozoites escape the liver and re-enter the bloodstream where they assault red blood cells, continue to grow and divide, and eventually kill the blood cells.

O When a scientist finds a new way to test a hypothesis, experimental methods do not change.
O Theories may be revised over time as information is discovered or technology is developed.
O When a scientist finds a new way to test a hypothesis, the original theory is made into a law.
Answer:
Theories may be revised over time as information is discovered or technology is developed.
Explanation:
A scientific theory is a term used when a statement tries to explain a natural phenomenon of nature based on scientific facts. In short, a theory is the representation of a set of hypotheses that was confirmed through an experiment and that tries to explain a phenomenon, but leaves room for revisions and updates to its explanation.
For this reason, we can say that theories are reformulated, revised and even discredited, when the advancement of scientific knowledge and technology allows the creation of new studies that show a different explanation and more consistent with reality.

Answer:
Explanation:
해파리 (cnidarians) have a worldwide distribution. Despite most being harmless, some species may cause local and also systemic reactions. 처치 of 해파리 envenomation is directed at: alleviating the local effects of venom, preventing further nematocyst discharges and controlling systemic reactions, including shock. In severe cases, the most important step is stabilizing and maintaining vital functions. With some 차이점 between species, there seems to be evidence and consensus on oral/topical analgesics, hot water and ice packs as effective painkillers and on 30 s application of domestic vinegar (4%–6% acetic acid) to prevent further discharge of unfired nematocysts remaining on the skin. Conversely, alcohol, methylated spirits and fresh water should be 조심스럽게 avoided, since they could massively discharge nematocysts; pressure immobilization bandaging should also be avoided, as laboratory studies show that it stimulates additional venom discharge from nematocysts. Most 처치 approaches are presently founded on 상대적으로 weak evidence; therefore, further research (especially randomized clinical trials) is strongly recommended. Dissemination of appropriate 처치 modalities should be deployed to better inform and educate those at risk. Adequate signage should be placed at 바닷가 to notify tourists of the jellyfish risk.
