Many aquatic birds secrete waxy organic substances that repel water. The birds use these substances to coat their feathers. An analysis of these substances would reveal that they are composed mostly of…
•Lipids
•Carbohydrates
•Nucleic Acids
•nucleic Acids
Answer:
The correct answer would be - lipids.
Explanation:
Many aquatic birds secrete a waxy organic substance which coats their feathers and this substance allows their feathers to repel the water which is helpful for their flying even after floating in the water.
An analysis of these substances would tell that these substances are composed of lipids as lipids are the only macromolecules that are hydrophobic which means they try to avoid water and not allow water to pass through them.

how does engineering impact the medical field give at least three examples
Answer:
Engineering has allowed for advancments in medicine far beyond what we thought was ever possible. One example is the ability to genomap, and from that new treatments and possibly cures for cancer are created. New tools are made that help in the everyday life of a medical provider, such as new clamps that can better grasp a vein or artery. Lastly, the development of new medicine through BioMed engineers has allowed for the treatment of kidney disease, and liver issues.

10) About 25% of the moon was visible on July 18th, what moon phase was occurring?
Answer:
(Lunar Phase)
Explanation:
In the movie “The Hunger Games,” the Capitol (a term used to refer to what we would call the government) produced genetically enhanced birds called jabber jays to spy on rebels. Unexpectedly, these birds bred with mockingbirds, creating a new hybrid bird called the mocking jay. The Capitol did not intend for this to happen, and the bird became a symbol of rebellion. What lessons can we draw about genetic engineering from these examples? Could a scenario like this, where a genetically engineered organism hybridizes with a wild animal or plant, happen in the real world? Why or why not?
Answer:
We can learn that crossing things that are not
together could lead to issues that could be avoided if not crossing them. Yes this could happen, it is possible to breed animals, like with dogs. Some breeds are more angry.

mention many ways to change how we use water, Which way do you think is the best and explain why.
Answer:
The easiest way to monitor the usage is to manage the water flowing into the home. (If you have a slow flow in your home now, you have much more incentive to watch your use!) - Take baths that consume ten times less water instead of taking a bath.
Explanation:
Ways to save the water:
Switch off the tap while your teeth are cleaned Insert your toilet cistern displacement unit to minimize the amount of water that is used with each flush Get a shorter tub. Short shower. Always use the laundry and dishwasher for maximum loads. Remove a drop tap. Build a drainage pipe with a water butt and water the plants Water the lawn instead of a pipe for watering.HELPPPP:

What are the environmental and economical
uses of soil?
Answer:
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.

landscape management attracts people to nature preserves and national parks what are the benefits to the wildlife in these areas?
Answer:
one benefits to wildlife in national and nature parks are, that there are is not hunting within the parks. not only does this protect the wildlife, it also sustains the balance of life. nature and wildlife parks allow a careful eye to be placed on the animals that are going extinct or are even victims of severe hunting. this allows this generation as well as their future offspring to be healthy and ensure safety. a benefit to the public would be the, scenic routes you can walk on a trail, besides walking and being outdoors, any contribution/ donations are ensured to go towards rehabilitation of the animals.
Explanation:
i made it up and it gave me 100%
Answer:
The benefits to wildlife in parks that humans create is that there is often no hunting allowed in those areas, as it is a recreational area for humans. This allows local wildlife populations to thrive without threat of hunters lowering their population. Organisms also can receive protections in parks if their population reaches a critical point in which they might have otherwise gone extinct. Furthermore they can create an area for injured animals who have undergone rehabilitation services to have an area free from large amounts of competition.

Answer:
Vultures, worms and crabs
Explanation:
Hope this helps
Three examples of detritivores are woodlice, dung flies, sea stars, etc.
What are detrivores?"Detrivores are heterotrophic animals that gain nutrients by consuming excrement as well as decomposing plant and animal materials". Detritus is the term for these items.
Detrivores are different from decomposers because decomposers cannot consume solid objects; instead, they release enzymes to break down and assimilate their meal on a molecular level. Earthworms, woodlice, sea stars, and millipedes are a few detrivores.
These are the animals that eat soil or other elements that are present in the soil or other material. So, they indirectly clean the environment by cleaning the material of the

Which amino acid sequence is coded for by the mRNA segment AUG-CCC-CAC-GAA-UAC?
Answer:
Met-Pro-His-Glu-Tyr
Explanation:
To discover what each amino acid sequence codes for, we have to look at a codon chart, a chart with all the possible amino acid combinations and what they code. After analyzing it, we can see that the sequence AUG codes for the amino acid methionine, CCC codes for the amino acid proline, CAC codes for the amino acid histidine, GAA codes for the amino acid glutamine, and UAC codes for the amino acid tyrosine.

What are melanin and carotene?
Suppose a person has one single mutation in their DNA and the first codon for the insulin gene now reads TAT instead of TAG. Using your codon chart, look up the amino acid that is coded for by the mutant DNA.
Answer:
Isoleucine
Explanation:
Using a codon chart, the gene TAT corresponds with AUA. U is Uracil and stands in place for Thymine since RNA does not use it. AUA results in the amino acid Isoleucine.
What is the shoal of sardines? What other fish can make shoals?
The shoals are often more than 7 km long, 1.5 km wide and 30 metres deep and are clearly visible from spotter planes or from the surface. Sardines group together when they are threatened. This instinctual behaviour is a defence mechanism, as lone individuals are more likely to be eaten than large groups.
The shoaling habit includes all the popular, common fish that belong to the Characin family (tetras), Cyprinidae family (barbs and danios) and Melanotaeniidae family (rainbow fish). There are even some species of catfish and cichlids that shoal.
Why do fish swim in shoals?Many kinds of fish prefer to swim together in groups called shoals. ... Shoaling can help fish because there are more eyes for spotting danger from predators or for finding food. Predators also find it more difficult to target a single victim in a big, moving group.
