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.
Answers
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.

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. .
Answers
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 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.

Do you think that governments should institute measures to control the human population? Please don’t send me those file things. Please just give me the answer.

The temperature is some 30C. The humidity stifling, the noise unbearable. In a yard between two enormous tea-drying sheds, a number of dark-skinned women patiently sit, each accompanied by an unwieldy looking cloth sack. They are clad in colourful saris, but look tired and shabby. This is hardly surprising - they have spent most of the day in nearby plantation fields, picking tea that will net them around two cents a kilo - barely enough to feed their large families.
Vivek Baid thinks he knows how to help them. He runs the Mission for Population Control, a project in eastern India which aims to bring down high birth rates by encouraging local women to get sterilised after their second child.
As the world reaches an estimated seven billion people, people like Vivek say efforts to bring down the world's population must continue if life on Earth is to be sustainable, and if poverty and even mass starvation are to be avoided. There is no doubting their good intentions. Vivek, for instance, has spent his own money on the project, and is passionate about creating a brighter future for India.
But critics allege that campaigners like Vivek - a successful and wealthy male businessman - have tended to live very different lives from those they seek to help, who are mainly poor women.
These critics argue that rich people have imposed population control on the poor for decades. And, they say, such coercive attempts to control the world's population often backfired and were sometimes harmful.
Population scare
Most historians of modern population control trace its roots back to the Reverend Thomas Malthus, an English clergyman born in the 18th Century who believed that humans would always reproduce faster than Earth's capacity to feed them.
Giving succour to the resulting desperate masses would only imperil everyone else, he said. So the brutal reality was that it was better to let them starve.
Rapid agricultural advances in the 19th Century proved his main premise wrong, because food production generally more than kept pace with the growing population.
But the idea that the rich are threatened by the desperately poor has cast a long shadow into the 20th Century.
From the 1960s, the World Bank, the UN and a host of independent American philanthropic foundations, such as the Ford and Rockefeller foundations, began to focus on what they saw as the problem of burgeoning Third World numbers.
The believed that overpopulation was the primary cause of environmental degradation, economic underdevelopment and political instability.
Massive populations in the Third World were seen as presenting a threat to Western capitalism and access to resources, says Professor Betsy Hartmann of Hampshire College, Massachusetts, in the US.
Which taxon includes the most specific characteristics?
Answers
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.

Choose the statement below that is true. Photosynthetic enzymes are denatured at high temperatures. Increasing temperature always increases the rate of photosynthesis. Too much carbon dioxide is toxic for plants. The main limiting factors are temperature, light intensity and oxygen concentration.
Answers
Answer:
The correct answer would be -
Photosynthetic enzymes are denatured at high temperatures
Too much carbon dioxide is toxic for plants
Explanation:
Temperature is a limiting factor for the rate of photosynthesis due to the fact the at high-temperature photosynthesis is affected as initially with an increase in temperature rate of photosynthesis but after a limit, it becomes constant and increasing above that will result in denaturing of the photosynthetic enzymes.
CO2 is also a limiting factor that limits the photosynthetic rate if too little or affects the photosynthesis in the too much amount by denying the O2 intake by soil and make leaves thick.
