Answer: As vertebrate animals, birds are ultimately related to all the other vertebrate animals that live or ever have lived on earth. But you may be surprised to learn that the family of vertebrates to which modern birds are most closely related is the crocodiles , which evolved, like dinosaurs, from a population of archosaur reptiles during the late Triassic period.

Several scientists travel to a remote coast to study the biodiversity of the area. How could the scientists calculate the species richness of the ecosystem?
A. counting the total number of different species
B. calculating the number of organisms in each trophic level
C. counting the total number of individual organisms
D. calculating the number of producers in the area
Answer:
A. counting the total number of different species
Explanation:
The only way to calculate the species richness in the ecosystem is counting the total number of different species. This is basically what species richness is, therefore it would be the best way to calculate it. Species Richness does not require that the scientists take into account the population of each species instead, each unique species found is counted as 1 towards the calculation of species richness.

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.
Explanation:
1. If a heterozygous individual (Aa) were crossed with another heterozygous individual (Aa), what
is the chance that their offspring would have a heterozygous genotype?
A 0%
B. 50%
C. 75%
D. 100%
Answer:
B
Explanation:
The chance that their offspring would have a heterozygous genotype is 50%. The correct option is B.
What is a heterozygous individual?In terms of genetics, being heterozygous means having inherited various alleles (variations) of a certain genomic marker from each biological parent. A person who has two copies of a genetic marker is said to be heterozygous for that marker.
When two heterozygous people are crossed, the offspring's genotype and phenotypic ratios will be predictable.
A person who is heterozygous for a gene has two distinct alleles. In this scenario, there would be a 50% probability that the person would inherit one allele and a 50% chance that they would receive the other allele.
There is a 1/4 chance of having children that are heterozygous for both genes.
Therefore, the correct option is B. 50%.

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.

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.
Give an example of 3 detrivores. On what do they feed?
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
Thus, examples are sea stars, sea cucumbers, dung flies, slugs, etc.

Answer:
Photosynthesis
Explanation:
is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!
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.

One of the first mutant genes to be studied in this species was golden. The mutant allele was discovered in a pigmentation mutant purchased from a pet store, which changed the color of the fish from the wild-type silver-white coloration to a pale golden color. Calculate the percent likelihood of golden offspring from a cross between a heterozygous wild-type male fish to a golden female fish a 0% b 50% c 25% d 100%
Answer:
b
Explanation:
Let the wild type trait, the silver-white, be represented by A allele and the mutant trait, the golden color, be represented by a allele.
Heterozygous wild-type male fish would be Aa
Golden female fish would be aa
Aa x aa
Aa Aa aa aa
2/4 Aa = silver-white
2/4 aa = golden color
Hence, the percent likelihood of golden offspring is 2/4 or 50%.
The correct option is b.
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.

d. All of the above
Explanation:
All of the given choices are reasons to study the ocean carbon cycle. The ocean occupies about 70% of the earth surface area and it plays important roles in carbon cycling.
The ocean acts as reservoir for carbon in many different ways especially due to the dissolution of this gas in it. It also releases a significant amount of carbon dioxide to the atmosphere due to the plethora of life within it. The field is also relatively new and more works must be done to understand this cycle.Answer:

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.
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.
