How will the increase in the tuna population affect the other populations? Be sure to explain whether the dolphin population, the squid population, and the herring population will change, and why.
Complete question:
Scientists have been studying four populations in one area of the Atlantic Ocean. In this area, both tuna and dolphins eat squid, and squid eat herring (a type of fish).
The data shows that recently the tuna population increased. How will the increase in the tuna population affect the other populations? Be sure to explain whether the dolphin population, the squid population, and the herring population will change, and why.
You will find the image in the attached files.
Answer:
Tunas´ population increasesSquids´ population decreases because more tuna eat themDolphins´ population decreases because there are fewer squids availableHerrings´ population increases because they do not suffer predation by squids.Explanation:
In the trophic web occurs a process of energy transference through different organisms placed at different levels. Each level feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
If any of the links change their population size (increasing it or decreasing it), it affects the superior links and the immediately anterior link.
In the exposed example of the trophic web, tuna feeds on squids. If the tuna population increases in size, there will be more individuals feeding on squids. Squids will be affected because too many animals are eating them, and they will not have enough time to reproduce and recover the normal population size. The mortality rate by predation is higher than the natality rate, meaning that the squid population will decrease.
Dolphins also feed on squids. But as the tuna population increases in size, competition for squid prey will be higher. Both species (tuna and dolphins) will compete for food. But tuna will eat more squids, and hence, dolphins will be affected and decrease in population size.
Usually, herrings are eaten by squids. But as the squids' population decreases, herrings will not suffer from predation, and their population will increase in size.
So, to sum up:
Tunas´ population increasesSquids´ population decreases because more tuna eat themDolphins´ population decreases because there are fewer squids availableHerrings´ population increases because they do not suffer predation by squids.

The nervous system is one system among several in the human body. In order to function, does the nervous system depend on other systems such as the muscular system or the respiratory system? Conversely, do these systems depend on the nervous system? Explain your reasoning for each answer.
Answer:
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.

Which taxon includes the most specific characteristics?
Answer:
Species taxon includes the most specific characteristics.
I hope this might be the answer for ur question ☺️
The most specific characteristics are seen in Species Taxon.
What is Taxon?Taxon is defined as the unit of taxonomy which are arranged in a hierarchy from kingdom to species.
The taxonomic classification was given by Carlos Linnaeus who is known as the Father of Taxonomy.
In descending order it is classified as:
Kingdom - Phylum - Class - Order - Family - Genus - Species
A taxon is usually known by a particular name and given a particular ranking and is given formal science name, its use is then governed by one of the nomenclature code specifying which scientific name is correct for particular grouping.
What is species?Species are the most specific taxon which share common traits and characteristics closely to each other and are capable of interbreeding.
It is the largest group of organisms in which any two individuals of the appropriate sexes or mating type can produce fertile offspring through sexual reproduction.
Types of species:
- Typological/ Morphological Species:
Individuals are having fixed properties as can be easily recognized by the modern taxonomist.
- Recognition/ Cohesion species:
Group of sexually reproducing organisms recognizing one another as potential mates.
- Genetically similar
- Phylogenetic/ Cladistics species:
These are the smallest group based on unique combination of character states in comparable individuals.
- Evolutionary species:
Set of species adapted to a particular set of resources called niche in the environment.
- Genetic Species:
Set of genetically isolated interbreeding populations.

Which of the following best supports the theory of continental drift?
A
South America and Africa have completely different rock layers.
B
A hurricane hits the Gulf of Mexico at the beginning of June.
C
Similar fossils are found on the coasts of South America and Africa.
D
North America and South America are connected by land.
Answer:
C
Similar fossils are found on the coasts of South America and Africa.
Continental drift is a hypothetical argument that affirms that the continents of the Earth shifted over the geological timeline. It says that the landmasses drifted over the oceans hence creating several continents and oceans.
The correct answer is:
Option C. Similar fossils are found on the coasts of South America and Africa.
The explanation for the correct answer is:
The continents either drifted away or clashed together to form present-day continents.Remains from similar species infer that South America and Africa used to be together.The theory of Pangaea states that all the continents were united once but due to a shift in tectonic plates the continents drifted apart.Therefore, alike fossils found in various continents supports the theory of continental drift.

Which of the following observations would provide the strongest evidence that two plants belong to different biological species?
A. There are variations in their RNA sequences.
B. The leaves and flowers show morphological differences.
C.They produce viable but sterile offspring.
D.They occupy unique habitats in an ecosystem. .
Answer:
the answer is C
Explanation:
Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.
The observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
The biological concept of species was developed by Ernst Mayr, who also develop the idea that species are metapopulation lineages.The biological concept of species states that mating between individuals of the same species produces viable offspring.The biological concept of species can be used to provide independent evidence for the presence of morphological and biological species.In conclusion, the observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).

what errors that could take place if a cell in m phase and g phase combine
Answer:
Explanation:
If a cell in the S phase come together and joined with a cell in the G1 phase, the nucleus of the G1 phase will suddenly jumped into S phase and this will result in the synthesis of DNA . If a cell then in the M phase joined with a cell in G1 phase, the nucleus of G1 will undergo mitosis and this will lead to the formation of a spindle and chromatin condensation even when duplication of chromosomes has not occur.

What is a kingdom?In biological classification, a kingdom is the second highest taxonomic rank below domain. It is used to group organisms based on their similarities and differences in characteristics and traits. The system of classification, known as Linnaean taxonomy, categorizes living things into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.
Each kingdom is defined by specific characteristics such as cell structure, mode of nutrition, and reproductive strategies. For example, the Monera kingdom consists of unicellular organisms with prokaryotic cells, while the Plantae kingdom includes multicellular organisms that produce their own food through photosynthesis.
The kingdom level of classification helps scientists understand the relationships and diversity of living organisms, which is important for fields such as ecology, evolutionary biology, and biotechnology.
