What is the shoal of sardines? What other fish can make shoals?
Answers
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.
Zebrafish (Danio rerio) is an important model organism in the field of genetics. 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%
Answers
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.

Which of the following best explains the importance of studying the ocean carbon cycle?
a. The oceans have a significant impact on the levels of atmospheric gases.
b. It is a new field of ocean science.
c. The ocean releases one quarter of the carbon dioxide in the atmosphere.
d. All of the above
Answers
Answer:
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:

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
Answers
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.

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%
Answers
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%.

landscape management attracts people to nature preserves and national parks what are the benefits to the wildlife in these areas?
Answers
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.

During passive transport, the molecules move from: *
A. Low to High Concentration (comfy --> crowded)
B. High to Low Concentration (crowded --> comfy)
Answers
Answer:
B. High to Low Concentration (crowded --> comfy)
Explanation:
Passive transport is defined as the transport of molecules from high concentration to low Concentration across cell membranes without using energy. Passive transport is based on the second law of thermodynamics. An example of passive transport is diffusion.
Hence, the correct answer is "B. High to Low Concentration (crowded --> comfy)".
Answer:
B. High to Low Concentration (crowded --> comfy)
Explanation:
In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.
